Certain facilities are equipped to handle TBI better than others; initial measures include transporting patients to an appropriate treatment center. Both during transport and in hospital the primary concerns are ensuring proper oxygen supply, maintaining adequate blood flow to the brain, and controlling raised intracranial pressure (ICP), since high ICP deprives the brain of badly needed blood flow and can cause deadly brain herniation. Other methods to prevent damage include management of other injuries and prevention of seizures. Some data supports the use of hyperbaric oxygen therapy to improve outcomes.

Neuroimaging is helpful but not flawless in detecting raised ICP. A more accurate way to measure ICP is to place a catheter into a ventricle of the brain, which has the added benefit of allowing cerebrospinal fluid to drain, releasing pressure in the skull. Treatment of raised ICP may be as simple as tilting the patient's bed and straightening the head to promote blood flow through the veins of the neck. Sedatives, analgesics and paralytic agents are often used. Hypertonic saline can improve ICP by reducing the amount of cerebral water (swelling), though it is used with caution to avoid electrolyte imbalances or heart failure. Mannitol, an osmotic diuretic, appears to be equally effective at reducing ICP. Some concerns; however, have been raised regarding some of the studies performed. Diuretics, drugs that increase urine output to reduce excessive fluid in the system, may be used to treat high intracranial pressures, but may cause hypovolemia (insufficient blood volume). Hyperventilation (larger and/or faster breaths) reduces carbon dioxide levels and causes blood vessels to constrict; this decreases blood flow to the brain and reduces ICP, but it potentially causes ischemia and is, therefore, used only in the short term. Administration of corticosteroids is associated with an increased risk of death, and so it is recommended that they not be given routinely.

Endotracheal intubation and mechanical ventilation may be used to ensure proper oxygen supply and provide a secure airway. Hypotension (low blood pressure), which has a devastating outcome in TBI, can be prevented by giving intravenous fluids to maintain a normal blood pressure. Failing to maintain blood pressure can result in inadequate blood flow to the brain. Blood pressure may be kept at an artificially high level under controlled conditions by infusion of norepinephrine or similar drugs; this helps maintain cerebral perfusion. Body temperature is carefully regulated because increased temperature raises the brain's metabolic needs, potentially depriving it of nutrients. Seizures are common. While they can be treated with benzodiazepines, these drugs are used carefully because they can depress breathing and lower blood pressure. TBI patients are more susceptible to side effects and may react adversely or be inordinately sensitive to some pharmacological agents. During treatment monitoring continues for signs of deterioration such as a decreasing level of consciousness.

Traumatic brain injury may cause a range of serious coincidental complications that include cardiac arrhythmias and neurogenic pulmonary edema. These conditions must be adequately treated and stabilised as part of the core care for these patients.

Surgery can be performed on mass lesions or to eliminate objects that have penetrated the brain. Mass lesions such as contusions or hematomas causing a significant mass effect (shift of intracranial structures) are considered emergencies and are removed surgically. For intracranial hematomas, the collected blood may be removed using suction or forceps or it may be floated off with water. Surgeons look for hemorrhaging blood vessels and seek to control bleeding. In penetrating brain injury, damaged tissue is surgically debrided, and craniotomy may be needed. Craniotomy, in which part of the skull is removed, may be needed to remove pieces of fractured skull or objects embedded in the brain. Decompressive craniectomy (DC) is performed routinely in the very short period following TBI during operations to treat hematomas; part of the skull is removed temporarily (primary DC). DC performed hours or days after TBI in order to control high intracranial pressures (secondary DC) has not been shown to improve outcome in some trials and may be associated with severe side-effects.

It is important to begin emergency treatment within the so-called "golden hour" following the injury. People with moderate to severe injuries are likely to receive treatment in an intensive care unit followed by a neurosurgical ward. Treatment depends on the recovery stage of the patient. In the acute stage the primary aim of the medical personnel is to stabilize the patient and focus on preventing further injury because little can be done to reverse the initial damage caused by trauma. Rehabilitation is the main treatment for the subacute and chronic stages of recovery. International clinical guidelines have been proposed with the aim of guiding decisions in TBI treatment, as defined by an authoritative examination of current evidence.

Pharmacotherapy is the utilization of drugs to treat an illness. There are several different drugs that have been used to alleviate symptoms experienced after a head injury including anti-depressants such as amitriptyline and sertraline. Use of these drugs has been associated with a decrease in depression and increased functioning in social and work environments. An antidiuretic called Desmopressin Acetate (DDAVP) has also been shown to improve memory performance in patients

Recent studies have examined the preventative effects of progesterone on brain injuries. Phase III trials are currently being conducted at 17 medical centers across the United States. Preliminary results have shown a 50% reduction in mortality in those treated with progesterone and showed an improved functional outcome.

Overall, the efficacy of pharmacotherapuetic treatments is dependent on the treatment being used and the symptoms being targeted by the treatment.

Most head injuries are of a benign nature and require no treatment beyond analgesics and close monitoring for potential complications such as intracranial bleeding. If the brain has been severely damaged by trauma, neurosurgical evaluation may be useful. Treatments may involve controlling elevated intracranial pressure. This can include sedation, paralytics, cerebrospinal fluid diversion. Second line alternatives include decompressive craniectomy (Jagannathan et al. found a net 65% favorable outcomes rate in pediatric patients), barbiturate coma, hypertonic saline and hypothermia. Although all of these methods have potential benefits, there has been no randomized study that has shown unequivocal benefit.

Clinicians will often consult clinical decision support rules such as the Canadian CT Head Rule or the New Orleans/Charity Head injury/Trauma Rule to decide if the patient needs further imaging studies or observation only. Rules like these are usually studied in depth by multiple research groups with large patient cohorts to ensure accuracy given the risk of adverse events in this area.

Patient education has been shown to be one of the most effective ways to decrease secondary symptoms seen with closed-head injuries. Patient education often includes working with a therapist to review symptom management and learn about returning to regular activities. Educational initiatives have also been shown to decrease the occurrence of PTSD in head-injury survivors.

According to the recommendations made by the Quebec Task Force, treatment for individuals with whiplash associated disorders grade 1–3 may include non-narcotic analgesics. Non-steroidal anti-inflammatory drugs may also be prescribed in the case of WAD 2 and WAD 3, but their use should be limited to a maximum of three weeks. Botulinum toxin A is used to treat involuntary muscle contraction and spasms. Botulinum toxin type-A is only temporary and repeated injections need to take place in order to feel the effects.

According to a year long follow-up study in 2008 on 186 patients, the WAD-classification and Quebec Task Force regimen were not linked to better clinical outcomes.

After exclusion of neck injury, observation should be continued for several hours. If repeated vomiting, worsening headache, dizziness, seizure activity, excessive drowsiness, double vision, slurred speech, unsteady walk, or weakness or numbness in arms or legs, or signs of basilar skull fracture develop, immediate assessment in an emergency department is warranted. After this initial period has passed, there is debate as to whether it is necessary to awaken the person several times during the first night, as has traditionally been done, or whether there is more benefit from uninterrupted sleep.

Physical and cognitive rest should be continued until all symptoms have resolved with most (80–90%) concussions resolving in seven to ten days, although the recovery time may be longer in children and adolescents. Cognitive rest includes reducing activities which require concentration and attention such as school work, video games, and text messaging. It has been suggested that even leisure reading can commonly worsen symptoms in children and adolescents and proposals include time off from school and attending partial days. Since students may appear 'normal', continuing education of relevant school personnel may be needed.

Those with concussion are generally prescribed rest, including adequate nighttime sleep as well as daytime rest. Rest includes both physical and cognitive rest until symptoms clear and a gradual return to normal activities at a pace that does not cause symptoms to worsen is recommended. Education about symptoms, their management, and their normal time course, can lead to an improved outcome.

For persons participating in athletics, the 2008 Zurich Consensus Statement on Concussion in Sport recommends that participants be symptom-free before restarting and then progress through a series of graded steps. These steps include:

- complete physical and cognitive rest

- light aerobic activity (less than 70% of maximum heart rate)

- sport-specific activities such as running drills and skating drills

- non-contact training drills (exercise, coordination, and cognitive load)

- full-contact practice

- full-contact games.

Only when symptom-free for 24 hours, should progression to the next step occur. If symptoms occur, the person should drop back to the previous asymptomatic level for at least another 24 hours. The emphasis is on remaining symptom free and taking it in medium steps, not on the steps themselves.

Medications may be prescribed to treat sleep problems and depression. Analgesics such as ibuprofen can be taken for headache, but paracetamol (acetaminophen) is preferred to minimize the risk of intracranial hemorrhage. Concussed individuals are advised not to use alcohol or other drugs that have not been approved by a doctor as they can impede healing. Activation database-guided EEG biofeedback has been shown to return the memory abilities of the concussed individual to levels better than the control group.

About one percent of people who receive treatment for MTBI need surgery for a brain injury. Observation to monitor for worsening condition is an important part of treatment. Health care providers recommend that those suffering from concussion return for further medical care and evaluation 24 to 72 hours after the concussive event if the symptoms worsen. Athletes, especially intercollegiate or professional, are typically followed closely by team athletic trainers during this period but others may not have access to this level of health care and may be sent home with minimal monitoring.

People may be released after assessment from hospital or emergency room to the care of a trusted person with instructions to return if they display worsening symptoms or those that might indicate an emergent condition such as: change in consciousness, convulsions, severe headache, extremity weakness, vomiting, new bleeding or deafness in either or both ears.

Though no pharmacological treatments exist for PCS, doctors may prescribe medications used for symptoms that also occur in other conditions; for example, antidepressants are used for the depression that frequently follows mTBI. Side effects of medications may affect people suffering the consequences of mTBI more severely than they do others, and thus it is recommended that medications be avoided if possible; there may be a benefit to avoiding narcotic medications. In addition, some pain medications prescribed for headaches can cause rebound headaches when they are discontinued.

Management of post-concussion syndrome typically involves treatments addressing specific symptoms; for example, people can take pain relievers for headaches and medicine to relieve depression or insomnia. Rest is advised, but is only somewhat effective. Physical and behavioral therapy may also be prescribed for problems such as loss of balance and difficulties with attention, respectively.

Symptoms remaining more than six months after trauma is labelled Whiplash syndrome. The main purpose with early rehabilitation is to reduce the risk for development of Whiplash syndrome. Early rehabilitation for whiplash depends on the grade category. It can be categorized as grade 0 being no pain to grade 4 with a cervical bone fracture or dislocation. Grade 4 obviously needs admission to hospital while grade 0-3 can be managed as outpatients. The symptoms from the potential injury to the cervical spine may be debilitating, and pain was reported to be one of the biggest stressor events experienced in daily living, so it is important to begin rehabilitation immediately to prevent future pain.

Current research supports that active mobilization rather than a soft collar results in a more prompt recovery both in the short and long term perspective. Furthermore, Schnabel and colleagues stated that the soft collar is not a suitable medium for rehabilitation, and the best way of recovery is to include an active rehabilitation program that includes physical therapy exercises and postural modifications. Another study found patients who participated in active therapy shortly after injury increased mobilization of the neck with significantly less pain within four weeks when compared to patients using a cervical collar.

Active treatments are light repetitive exercises that work the area to maintain normality. Basic information is also given to teach the patient that exercises as instructed will not cause any damage to their neck. These exercises are done at home or under the care of a health professional. When beginning a rehabilitation regimen, it's important to begin with slow movements which include cervical rotation until pain threshold three to five times per day, flexion and extension of the shoulder joint by moving the arms up and down two to three times, and combining shoulder raises while inhaling and releasing the shoulder raise while exhaling. Soderlund and colleagues also recommend that these exercises should be done every day until pain starts to dissipate. Early mobilization is important for preventing chronic pain, but pain experienced from these exercises might cause psychological symptoms that could have negative impact on recovery. Rosenfeld found that doing active exercises as often as once every waken hour during one month after trauma decreases the need for sick leave three years after trauma from 25% to 5.7%.

Passive treatments such as acupuncture, massage therapy, and stimulation may sometimes be used as a complement to active exercises. Return to normal activities of daily living should be encouraged as soon as possible to maximize and expedite full recovery.

For chronic whiplash patients, rehabilitation is recommended. Patients who entered a rehabilitation program said they were able to control their pain, they continued to use strategies that were taught to them, and were able to go back to their daily activities.

Prevention of MTBI involves general measures such as wearing seat belts and using airbags in cars. Older people are encouraged to reduce fall risk by keeping floors free of clutter and wearing thin, flat, shoes with hard soles that do not interfere with balance.

Protective equipment such as headgear has been found to reduce the number of concussions in athletes and improvements in the design of helmets may decrease the number and severity further. New "Head Impact Telemetry System" technology is being placed in helmets to study injury mechanisms and may generate knowledge that will potentially help reduce the risk of concussions among American Football players. Self-reported concussion rates among U-20 and elite rugby union players in Ireland are 45–48%. Half of these injuries go unreported. Changes to the rules or enforcing existing rules in sports, such as those against "head-down tackling", or "spearing", which is associated with a high injury rate, may also prevent concussions.

Stingers can be prevented by wearing protective gear, such as butterfly restrictors, designed to protect the head and neck from being forced into unnatural positions. This equipment is more feasible in positions where unrestricted head and neck movement is not required, such as American football lineman, than in positions like quarterback, where such movement is integral. Regardless of equipment, it is important to report even minor symptoms to an athletic trainer or team physician, and to allow appropriate recovery time.

In children with uncomplicated minor head injuries the risk of intra cranial bleeding over the next year is rare at 2 cases per 1 million. In some cases transient neurological disturbances may occur, lasting minutes to hours. Malignant post traumatic cerebral swelling can develop unexpectedly in stable patients after an injury, as can post traumatic seizures. Recovery in children with neurologic deficits will vary. Children with neurologic deficits who improve daily are more likely to recover, while those who are vegetative for months are less likely to improve. Most patients without deficits have full recovery. However, persons who sustain head trauma resulting in unconsciousness for an hour or more have twice the risk of developing Alzheimer's disease later in life.

Head injury may be associated with a neck injury. Bruises on the back or neck, neck pain, or pain radiating to the arms are signs of cervical spine injury and merit spinal immobilization via application of a cervical collar and possibly a long board.If the neurological exam is normal this is reassuring. Reassessment is needed if there is a worsening headache, seizure, one sided weakness, or has persistent vomiting.

To combat overuse of Head CT Scans yielding negative intracranial hemorrhage, which unnecessarily expose patients to radiation and increase time in the hospital and cost of the visit, multiple clinical decision support rules have been developed to help clinicians weigh the option to scan a patient with a head injury. Among these are the Canadian Head CT rule, the PECARN Head Injury/Trauma Algorithm, and the New Orleans/Charity Head Injury/Trauma Rule all help clinicians make these decisions using easily obtained information and noninvasive practices.

Since cerebral swelling presents a danger to the patient, treatment of cerebral contusion aims to prevent swelling. Measures to avoid swelling include prevention of hypotension (low blood pressure), hyponatremia (insufficient sodium), and hypercapnia (increased carbon dioxide in the blood). Due to the danger of increased intracranial pressure, surgery may be necessary to reduce it. People with cerebral contusion may require intensive care and close monitoring.

The first-line treatment for a muscular strain in the acute phase include five steps commonly known as P.R.I.C.E.

- Protection: Apply soft padding to minimize impact with objects.

- Rest: Rest is necessary to accelerate healing and reduce the potential for re-injury.

- Ice: Apply ice to induce vasoconstriction, which will reduce blood flow to the site of injury. Never ice for more than 20 minutes at a time.

- Compression: Wrap the strained area with a soft-wrapped bandage to reduce further diapedesis and promote lymphatic drainage.

- Elevation: Keep the strained area as close to the level of the heart as is possible in order to promote venous blood return to the systemic circulation.

Immediate treatment is usually an adjunctive therapy of NSAID's and Cold compression therapy. Controlling the inflammation is critical to the healing process. Cold compression therapy acts to reduce swelling and pain by reducing leukocyte extravasation into the injured area. NSAID's such as Ibuprofen/paracetamol work to reduce the immediate inflammation by inhibiting Cox-1 & Cox-2 enzymes, which are the enzymes responsible for converting arachidonic acid into prostaglandin. However, NSAIDs, including aspirin and ibuprofen, affect platelet function (this is why they are known as "blood thinners") and should not be taken during the period when tissue is bleeding because they will tend to increase blood flow, inhibit clotting, and thereby increase bleeding and swelling. After the bleeding has stopped, NSAIDs can be used with some effectiveness to reduce inflammation and pain.

A new treatment for acute strains is the use of platelet rich plasma (PRP) injections which have been shown to accelerate recovery from non surgical muscular injuries.

It is recommended that the person injured should consult a medical provider if the injury is accompanied by severe pain, if the limb cannot be used, or if there is noticeable tenderness over an isolated spot. These can be signs of a broken or fractured bone, a sprain, or a complete muscle tear.

Treatment has traditionally been splenectomy. However, splenectomy is avoided if possible, particularly in children, to avoid the resulting permanent susceptibility to bacterial infections. Most small, and some moderate-sized lacerations in stable patients (particularly children) are managed with hospital observation and sometimes transfusion rather than surgery. Embolization, blocking off of the hemorrhaging vessels, is a newer and less invasive treatment. When surgery is needed, the spleen can be surgically repaired in a few cases, but splenectomy is still the primary surgical treatment, and has the highest success rate of all treatments.

Initial care in the hospital, as in the prehospital setting, aims to ensure adequate airway, breathing, cardiovascular function, and spinal immobilization. Imaging of the spine to ascertain presence of SCI may need to wait if emergency surgery is needed to stabilize a life-threatening injury. Acute SCI merits treatment in an intensive care unit, especially injuries to the cervival spinal cord. Patients with SCI need repeated neurological assessments and treatment by neurosurgeons.

If the systolic blood pressure falls below 90 mmHg within days of the injury, blood supply to the spinal cord may be reduced, resulting in further damage. Thus it is important to maintain the blood pressure using a central venous catheter, intravenous fluids, and vasopressors, and to treat cases of shock. Mean arterial blood pressure is measured and kept at 85 to 90 mmHg for seven days after injury. The treatment for shock from blood loss (hypovolemic shock) is different from that for neurogenic shock, and could harm people with the latter type, so it is necessary to determine why someone is in shock. However it is also possible for both causes to exist at the same time. Another important aspect of care is prevention of hypoxia (insufficient oxygen in the bloodstream), which could deprive the spinal cord of much-needed oxygen. People with cervical injuries may experience a dangerously slowed heart rate; treatment to speed it up include atropine and electrical cardiac pacing.

Swelling can cause further damage to the spinal cord by reducing the blood supply and causing ischemia, which can give rise to an ischemic cascade with a release of toxins that damages neurons. Thus treatment is often geared toward limiting this secondary injury. People are sometimes treated with drugs to reduce swelling. The corticosteroid drug methylprednisolone is commonly used within eight hours of the injury, but its use is controversial because of side effects. Studies have shown high dose methylprednisolone may improve outcomes if given within 6 hours of injury. However, the improvement shown by clinical trials has been inconclusive, and comes at the cost of increased risk of serious infection or sepsis, gastrointestinal bleeding, and pneumonia. Thus organizations that set clinical guidelines have increasingly stopped recommending methylprednisolone in the treatment of acute SCI.

Surgery may be necessary, e.g. to relieve excess pressure on the cord, to stabilize the spine, or to put vertebrae back in their proper place. In cases involving instability or compression, failing to operate can lead to worsening of the condition. Surgery is also necessary when something is pressing on the cord, such as bone fragments, blood, material from ligaments or intervertebral discs, or a lodged object from a penetrating injury. Although the ideal timing of surgery is still debated, studies have found that earlier surgical intervention (within 24 hours of injury) is associated with better outcomes. Sometimes a patient has too many other injuries to be a surgical candidate this early. Surgery is controversial because it has potential complications (such as infection), so in cases where it is not clearly needed (e.g. the cord is being compressed), doctors must decide whether to perform surgery based on aspects of the patient's condition and their own beliefs about its risks and benefits.

In cases where a more conservative approach is chosen, bed rest, cervical collars, immobilizing devices, and optionally traction are used. Surgeons may opt to put traction on the spine to remove pressure from the spinal cord by putting dislocated vertebrae back into alignment, but herniation of intervertebral disks may prevent this technique from relieving pressure. "Gardner-Wells tongs" are one tool used to exert spinal traction to reduce a fracture or dislocation and to immobilize the affected areas.

Stingers are best diagnosed by a medical professional. This person will assess the athlete's pain, range of head and neck motion, arm numbness, and muscle strength. Often, the affected athlete is allowed to return to play within a short time, but persistent symptoms will result in removal. Athletes are also advised to receive

regular evaluations until symptoms have ceased. If they have not after two weeks, or increase, additional tests such as magnetic resonance imaging (MRI) can be performed to detect a more serious injury, such as a herniated disc.

The order of treatments applied depends on whether the athlete's main complaint is pain or weakness. Both can be treated with an analgesic, anti-inflammatory medication, ice and heat, restriction of movement, and if necessary, cervical collar or traction. Surgery is only necessary in the most severe cases.

Treatment for brachial plexus injuries includes orthosis/splinting, occupational or physical therapy and, in some cases, surgery. Some brachial plexus injuries may heal without treatment. Many infants improve or recover within 6 months, but those that do not have a very poor outlook and will need further surgery to try to compensate for the nerve deficits. The ability to bend the elbow (biceps function) by the third month of life is considered an indicator of probable recovery, with additional upward movement of the wrist, as well as straightening of thumb and fingers an even stronger indicator of excellent spontaneous improvement. Gentle range of motion exercises performed by parents, accompanied by repeated examinations by a physician, may be all that is necessary for patients with strong indicators of recovery.

The exercises mentioned above can be done to help rehabilitate from mild cases of the injury. However, in more serious brachial plexus injuries surgical interventions can be used. Function can be restored by nerve repairs, nerve replacements, and surgery to remove tumors causing the injury. Another crucial factor to note is that psychological problems can hinder the rehabilitation process due to a lack of motivation from the patient. On top of promoting a lifetime process of physical healing, it is important to not overlook the psychological well-being of a patient. This is due to the possibility of depression or complications with head injuries.

Options include operative or non-operative treatment. If the dislocation is less than 2 mm, the fracture can be managed with casting for six weeks. The patient's injured limb cannot bear weight during this period. For severe Lisfranc injuries, open reduction with internal fixation (ORIF) and temporary screw or Kirschner wire (K-wire) fixation is the treatment of choice. The foot cannot be allowed to bear weight for a minimum of six weeks. Partial weight-bearing may then begin, with full weight bearing after an additional several weeks, depending on the specific injury. K-wires are typically removed after six weeks, before weight bearing, while screws are often removed after 12 weeks.

When a Lisfranc injury is characterized by significant displacement of the tarsometatarsal joint(s), nonoperative treatment often leads to severe loss of function and long-term disability secondary to chronic pain and sometimes to a planovalgus deformity. In cases with severe pain, loss of function, or progressive deformity that has failed to respond to nonoperative treatment, mid-tarsal and tarsometatarsal arthrodesis (operative fusion of the bones) may be indicated.

There are many treatments to facilitate the process of recovery in people who have brachial plexus injuries. Improvements occur slowly and the rehabilitation process can take up to many years. Many factors should be considered when estimating recovery time, such as initial diagnosis of the injury, severity of the injury, and type of treatments used. Some forms of treatment include nerve grafts, medication, surgical decompression, nerve transfer, physical therapy, and occupational therapy.

Rest, Ice, Compression and Elevation (RICE) are standard treatments in the first 48 hours of an injury to the hip pointer. After 48 hours, patients can begin gently stretching, strengthening exercises, flexibility and coordination. For the first 7–10 days, patients can take anti-inflammatories such as ibuprofen and apply ice. Since this injury is very painful, recovery is usually very slow. When the person is without pain, sports massage and range-of-motion activities may reduce tension and swelling and prevent scar tissue buildup. Furthermore, an injection of corticosteroids into the affected area may reduce symptoms in the short term and accelerate rehabilitation. Operative treatment is rarely indicated and is reserved for patients suffering from significant displacement or fractures of the bones.

To prevent hip pointer, the equipment must be adequate in the sport and be well positioned and good size. It should also maintain excellent flexibility, strength and endurance of the hip, pelvis and lower back muscles.

The first line of treatment is often to treat the patients pain with neuropathic drugs such as tricyclic antidepressants, serotonin reuptake inhibitors, and anticonvulsants. The second lines of drugs to treat pain are non-steroidal anti-inflammatories, tramadol, and opioids. Other techniques used to facilitate healing of the nerve and pain are either static or dynamic splinting that can both help protect the injured part as well as improve function. Sometimes surgery is an option, although the prognosis is still very poor of regaining function of the affected nerve. The goal of surgery is to join healthy nerve to unhealthy nerve. The most common surgical techniques include external neurolysis, end-to-end repair, nerve grafting, and nerve transfer from somewhere else in the body.

There are some preliminary studies that seem to indicate that treatment with hydrogen sulfide (HS) can have a protective effect against reperfusion injury.

Injury is damage to the body caused by external force. This may be caused by accidents, falls, hits, weapons, and other causes. Major trauma is injury that has the potential to cause prolonged disability or death.

In 2013, 4.8 million people died from injuries, up from 4.3 million in 1990. More than 30% of these deaths were transport-related injuries. In 2013, 367,000 children under the age of five died from injuries, down from 766,000 in 1990. Injuries are the cause of 9% of all deaths, and are the sixth-leading cause of death in the world.
