Treatment of a subdiaphragmatic abscess is an operative treatment that is performed in a hospital.
Transthoracic (transpleural) or transabdominal opening of the sub-diaphragmatic abscess and removal of pus from its cavity (by means of suction) are performed. Then the cavity is washed with antiseptic means and drainages are established with suturing the wound.
After this, drug treatment continues, and here the main drugs are antibiotics. First of all, by parenteral administration, preparations of the cephalosporins group are used: Cefotaxime, Cefazolin, Ceftriaxone, etc., which are administered either intramuscularly or intravenously (dropwise) - 0.25-0.5 g every 8 hours (in severe cases, 1 -2 g).
Flukloxacillin, Trimethoprim-sulfamethoxazole (Biseptol, Bactrim, Co-trimoxazole, Septrim and other trade names), Clindamycin (Dalacin, Klindachin, Klitsimin) are also used.
Antibiotic-lincosamide Clindamycin is prescribed in the form of injections - 2.5-2.8 g per day. Among its contraindications, only the presence of enteritis or colitis are noted. However, like all antibacterial drugs, this medicine can give side effects (changes in blood, urticaria, lowering blood pressure, abdominal pain, nausea, diarrhea, intestinal dysbiosis).
