Failure to relieve the pressure can result in necrosis of tissue in that compartment, since capillary perfusion will fall leading to increasing oxygen deprivation of those tissues. This can cause Volkmann's contracture in affected limbs. As intercompartmental pressure rises during compartment syndrome, perfusion within the compartment is reduced leading to ischemia, which if left untreated, results in necrosis of nerves and muscles of the compartment (Shears, 2006). Rhabdomyolysis and subsequent renal failure are also possible complications.
Acute compartment syndrome is a medical emergency requiring immediate surgical treatment, known as a fasciotomy, to allow the pressure to return to normal. Although only one compartment is affected, fasciotomy is done to release all compartments. For instance, if only the deep posterior compartment of a leg is affected, the treatment would be fasciotomy (with medial and lateral incisions) to release all compartments of the leg in question, namely the anterior, lateral, superficial posterior and deep posterior.
An acute compartment syndrome has some distinct features such as swelling of the compartment due to inflammation and venous occlusion. Decompression of the nerve traversing the compartment might alleviate the symptoms (Rorabeck, 1984). Until definitive fasciotomy can be performed, the extremity should be placed at the level of the heart. Hypotension should also be avoided, as this decreases perfusion pressure to the compartment. Supplemental oxygen also optimizes tissue and neural oxygenation.
Surgical intervention is usually given to those individuals who have increased instability of their cervical spine, which cannot be resolved by conservative management alone. Further indications for surgery include a neurological decline in spinal cord function in stable patients as well as those who require cervical spinal decompression.
In many cases, individuals with CCS can experience a reduction in their neurological symptoms with conservative management. The first steps of these intervention strategies include admission to an intensive care unit (ICU) after initial injury. After entering the ICU, early immobilization of the cervical spine with a neck collar would be placed on the patient to limit the potential of further injury. Cervical spine restriction is maintained for approximately six weeks until the individual experiences a reduction in pain and neurological symptoms. Inpatient rehabilitation is initiated in the hospital setting, followed by outpatient physical therapy and occupational therapy to assist with recovery.
An individual with a spinal cord injury may have many goals for outpatient occupational and physiotherapy. Their level of independence, self-care, and mobility are dependent on their degree of neurological impairment. Rehabilitation organization and outcomes are also based on these impairments. The physiatrist, along with the rehabilitation team, work with the patient to develop specific, measurable, action-oriented, realistic, and time-centered goals.
With respect to physical therapy interventions, it has been determined that repetitive task-specific sensory input can improve motor output in patients with central cord syndrome. These activities enable the spinal cord to incorporate both supraspinal and afferent sensory information to help recover motor output. This occurrence is known as "activity dependent plasticity". Activity dependant plasticity is stimulated through such activities as: locomotor training, muscle strengthening, voluntary cycling, and functional electrical stimulation (FES) cycling
The Canadian Cardiovascular Society (CCS) recommends surgical intervention for these indications:
- Limited exercise capacity (NYHA III-IV)
- Increasing heart size (cardiothoracic ratio greater than 65%)
- Important cyanosis (resting oxygen saturation less than 90% - level B)
- Severe tricuspid regurgitation with symptoms
- Transient ischemic attack or stroke
The CCS further recommends patients who require operation for Ebstein's anomaly should be operated on by congenital heart surgeons who have substantial specific experience and success with this operation. Every effort should be made to preserve the native tricuspid valve.
Ebstein's cardiophysiology typically presents as an (antidromic) AV reentrant tachycardia with associated pre-excitation. In this setting, the preferred medication treatment agent is procainamide. Since AV-blockade may promote conduction over the accessory pathway, drugs such as beta blockers, calcium channel blockers, and digoxin are contraindicated.
If atrial fibrillation with pre-excitation occurs, treatment options include procainamide, flecainide, propafenone, dofetilide, and ibutilide, since these medications slow conduction in the accessory pathway causing the tachycardia and should be administered before considering electrical cardioversion. Intravenous amiodarone may also convert atrial fibrillation and/or slow the ventricular response.
There is no specific treatment for measles. Most people with uncomplicated measles will recover with rest and supportive treatment.
Patients who become sicker may be developing medical complications. Some people will develop pneumonia as a consequence of infection with the measles virus. Other complications include ear infections, bronchitis (either viral bronchitis or secondary bacterial bronchitis), and brain inflammation. Brain inflammation from measles has a mortality rate of 15%. While there is no specific treatment for brain inflammation from measles, antibiotics are required for bacterial pneumonia, sinusitis, and bronchitis that can follow measles.
All other treatment addresses symptoms, with ibuprofen or paracetamol to reduce fever and pain and, if required, a fast-acting medication to dilate the airways for cough. As for aspirin, some research has suggested a correlation between children who take aspirin and the development of Reye syndrome. Some research has shown aspirin may not be the only medication associated with Reye, and even antiemetics have been implicated. The link between aspirin use in children and Reye syndrome development is weak at best, if not actually nonexistent. Nevertheless, most health authorities still caution against the use of aspirin for any fevers in children under 16.
The use of vitamin A during treatment is recommended by the World Health Organization to decrease the risk of blindness. A systematic review of trials into its use found no significant reduction in overall mortality, but it did reduce mortality in children aged under two years.
It is unclear if zinc supplementation in children with measles affects outcomes.
Measles antibodies are transferred from mothers who have been vaccinated against measles or who have been previously infected with measles to their children while they are still in the womb. Such antibodies will usually give newborn infants some immunity against measles, but such antibodies are gradually lost over the course of the first six months of life. Infants under one year of age whose maternal anti-measles antibodies have disappeared become susceptible to infection with the measles virus.
In developed countries, it is recommended that children be immunized against measles at 12 months, generally as part of a three-part MMR vaccine (measles, mumps, and rubella). The vaccine is generally not given before this age because such infants respond inadequately to the vaccine due to an immature immune system. A second dose of the vaccine is usually given to children between the ages of four and five, to increase rates of immunity. Vaccination rates have been high enough to make measles relatively uncommon. Adverse reactions to vaccination are rare, with fever and pain at the injection site being the most common. Life-threatening adverse reactions occur in less than one per million vaccinations (<0.0001%).
In developing countries where measles is endemic, WHO doctors recommend two doses of vaccine be given at six and nine months of age. The vaccine should be given whether the child is HIV-infected or not. The vaccine is less effective in HIV-infected infants than in the general population, but early treatment with antiretroviral drugs can increase its effectiveness. Measles vaccination programs are often used to deliver other child health interventions, as well, such as bed nets to protect against malaria, antiparasite medicine and vitamin A supplements, and so contribute to the reduction of child deaths from other causes.
The Advisory Committee on Immunization Practices (ACIP) has long recommended that all adult international travelers who do not have positive evidence of previous measles immunity receive two doses of MMR vaccine before traveling. Despite this, a retrospective study of pre-travel consultations with prospective travelers at CDC-associated travel clinics found that of the 16% of adult travelers who were considered eligible for vaccination, only 47% underwent vaccination during the consultation; of these, patient refusal accounted for nearly half (48%), followed by healthcare provider decisions (28%) and barriers in the health system (24%).
