The main goal of treatment is to remove the cause of the phlegmonous process in order to achieve effective treatment and prevention of recidives.

If the patient's condition is mild and signs of inflammatory process are present without signs of infiltrates, then conservative treatment with antibiotics is sufficient.

If the patient's condition is severe, however, immediate operation is usually necessary with application of drainage system. All of these are done under general anaesthesia. During operation, the cavity or place of phlegmonous process are washed with antiseptic, antibiotic solutions and proteolyic ferments.

In post-operative period, patients are treated with intravenous antibiotics, haemosorbtion, vitaminotherapy. Additionally, the use of i/v or i/m antistaphylococci γ-globulin or anatoxin can be taken as immunotherapy.

During operation of phlegmon dissection at any location, it is important:

1. to avoid spreading of pus during operation;

2. to take into account the cosmetic value of the operating site, especially when treating phlegmmonous process of the face; and

3. to avoid damaging nerves.

Commonly by bacteria – streptococci, spore and non-spore forming anaerobes, etc.

Factors affecting the development of phlegmons are virulence of bacteria and immunity strength.

As the infection is usually transmitted into humans through animal bites, antibiotics usually treat the infection, but medical attention should be sought if the wound is severely swelling. Pasteurellosis is usually treated with high-dose penicillin if severe. Either tetracycline or chloramphenicol provides an alternative in beta-lactam-intolerant patients. However, it is most important to treat the wound.

Initial management of a patient with acute pancreatitis consists of supportive care with fluid resuscitation, pain control, and nutritional support.

Pasteurellosis is an infection with a species of the bacterial genus "Pasteurella", which is found in humans and other animals.

"Pasteurella multocida" (subspecies "P. m. septica" and "P. m. multocida") is carried in the mouth and respiratory tract of various animals, including pigs. It is a small, Gram-negative bacillus with bipolar staining by Wayson stain. In animals, it can originate fulminant septicaemia (chicken cholera), but is also a common commensal.

Until taxonomic revision in 1999, "Mannheimia" spp. were classified as "Pasteurella" spp., and infections by organisms now called "Mannheimia" spp., as well as by organisms now called "Pasteurella" spp., were designated as pasteurellosis. The term "pasteurellosis" is often still applied to mannheimiosis, although such usage has declined.

Abdominal pain is often the predominant symptom in patients with acute pancreatitis and should be treated with analgesics.

Opioids are safe and effective at providing pain control in patients with acute pancreatitis. Adequate pain control requires the use of intravenous opiates, usually in the form of a patient-controlled analgesia pump. Hydromorphone or fentanyl (intravenous) may be used for pain relief in acute pancreatitis. Fentanyl is being increasingly used due to its better safety profile, especially in renal impairment. As with other opiates, fentanyl can depress respiratory function. It can be given both as a bolus as well as constant infusion.

Meperidine has been historically favored over morphine because of the belief that morphine caused an increase in sphincter of Oddi pressure. However, no clinical studies suggest that morphine can aggravate or cause pancreatitis or cholecystitis. In addition, meperidine has a short half-life and repeated doses can lead to accumulation of the metabolite normeperidine, which causes neuromuscular side effects and, rarely, seizures.

Acute appendicitis is typically managed by surgery. However, in uncomplicated cases, antibiotics are effective and safe. While antibiotics are effective for treating uncomplicated appendicitis, 26% of people had a recurrence within a year and required eventual appendectomy. They work less well if an appendicolith is present. Cost effectiveness of surgery versus antibiotics is unclear.

Hospital lengths of stay typically range from a few hours to a few days but can be a few weeks if complications occur. The recovery process may vary depending on the severity of the condition: if the appendix had ruptured or not before surgery. Appendix surgery recovery is generally a lot faster if the appendix did not rupture. It is important that people undergoing surgery respect their doctor's advice and limit their physical activity so the tissues can heal faster. Recovery after an appendectomy may not require diet changes or a lifestyle change.

Length of hospital stays for appendicitis varies on the severity of the condition. A study from the United States found that in 2010, the average appendicitis hospital stay was 1.8 days. For stays where the person's appendix had ruptured, the average length of stay was 5.2 days.

After surgery, the patient will be transferred to a postanesthesia care unit so his or her vital signs can be closely monitored to detect anesthesia- or surgery-related complications. Pain medication may be administered if necessary. After patients are completely awake, they are moved to a hospital room to recover. Most individuals will be offered clear liquids the day after the surgery, then progress to a regular diet when the intestines start to function properly. Patients are recommended to sit up on the edge of the bed and walk short distances several times a day. Moving is mandatory and pain medication may be given if necessary. Full recovery from appendectomies takes about four to six weeks but can be prolonged to up to eight weeks if the appendix had ruptured.
