[Perioperative management of focal liver diseases by ofloxacin].

Perioperative use of ofloxacin for prophylaxis was investigated in 20 patients with focal hepatic formations (hemangioma, adenocarcinoma, echinococcosis). First dose of ofloxacin (200 mg) was given intravenously 15 min before operation. After operation ofloxacin was used intravenously (400 mg daily) for 5 days. Pharmacokinetic investigation demonstrated that perioperative intravenous use of ofloxacin provided concentrations in blood and hepatic tissue satisfactory for potential microflore inhibition. Immunological monitoring demonstrated positive dynamics on 5-7 days after operation. dynamics depended on nosology of the focal hepatic formation. Ofloxacin use for prophylaxis in the operated patients with focal hepatic formations was efficient for profilaxy of postoperation infective complications.

[Use of ceftriaxone in the prevention of postoperative purulent complications after surgery on the stomach and small intestine].

Ceftriaxone was administered intravenously in a single dose of 1.0 g 15 minutes prior to surgical intervention for peptic ulcer and gastric or duodenum tumor in 31 patients at the age of 33 to 74 years. In all the patients primary adhesion of the surgical wound was recorded. No signs of local or general infection were observed. The indices of the total blood count, urinalysis and blood biochemical analysis came to normal by the 5th or the 7th day of the postoperative period. The levels of ceftriaxone in the blood, urine, stomach wall, small intestine tissues and subcutaneous fat were evaluated. The indices of the cellular and humoral immunity in the pre- and postoperative periods in the patients prophylactically treated with ceftriaxone were analyzed.

[Clinical and laboratory study of cefodizime (Modivid) in prophylaxis and treatment of surgical patients].

The results of the clinical and laboratory study of the efficacy of the prophylactic and therapeutic use of cefodizime (modivid) in patients with chronic calculous cholecystitis and burns are presented. Expediency of the preoperative prophylactic use of the drug and its significance in the treatment of infectious complications of the burn disease were verified. The immunological investigation gave evidence of an increase of the phagocytosis functional activity when cefodizime (modivid) was used prophylactically in cholecystectomy.

[Use of aztreonam for the purpose of preventing postoperative purulent complications].

The efficacy of the prophylactic use of azthreonam, a monocyclic beta lactam antibiotic, was studied in 20 patients operated for liver diseases. The drug was administered intramuscularly in a dose of 1 g 30 minutes prior to the operation. During the postoperative period the drug was administered in a dose of 1 g 4-5 times a day for 4 to 5 days. The clinical effect in all the patients was good: no elevation of the body temperature above 37.5 degrees C and no suppuration of the operation wound. Adverse reaction to the treatment were not observed. 135 clinical isolates were tested for the susceptibility to azthreonam. The most susceptible gram-negative bacteria were the following: E coli (100 per cent), P. mirabilis (100 per cent), M. morganii (100 per cent), P. rettgeri (100 per cent) and Citrobacter sp. (84 per cent). P. aeruginosa, Acinetobacter, P. vulgaris and Enterobacter were less susceptible (64, 50, 50 and 47.5 per cent respectively). All the S. aureus isolates were resistant.

Aztreonam↗

[Use of imipenem in the treatment of patients with surgical infection].

The efficacy of thienam, a product of Merck, Sharp and Dohme (USA) composed of imipenem and cylastatin was studied in the treatment of 52 patients with surgical infection. In 48 and 4 patients the drug was used therapeutically and prophylactically respectively. When the drug was used therapeutically the recovery and improvement were observed in 41 out of 44 patients (93.2 per cent), 4 patients being excluded from the treatment group because of adverse reactions such as hyperthermia and skin eruption. When the drug was used prophylactically the recovery and improvement were stated in all the 4 patients. The pathogens were eradicated in the wound in 40 patients (91 per cent). 114 clinical isolates were tested and the imipenem resistance was detected only in 6.5 per cent of the Staphylococcus aureus strains, in 20 per cent of the Pseudomonas aeruginosa strains and in 50 per cent of the P. mirabilis and P. vulgaris strains. All the isolates of Escherichia coli, Enterobacter, Acinetobacter and Citrobacter were susceptible or moderately susceptible to imipenem.

[Cefpiramide (Tamicin) in the treatment of purulent complications of abdominal surgery].

Fifty patients with purulent infection of the abdominal cavity were treated with cefpiramide (Lek, Slovania). The analysis of the results showed that the clinical effect was favourable in 92 percent of the patients. The bacteriological efficacy amounted to 65.2 percent. The index of the isolates susceptibility was high (72 percent at the average). The concentration of cefpiramide in the bile from the bile common duct was low (23 micrograms/ml) as a result of its partial or complete obstruction. The adverse reaction (diarrhea) was stated in 1 patient.

[Effectiveness of pefloxacin in the surgical clinic].

Pefloxacin (Rhone-Poulenc, France) was used prophylactically and therapeutically in 8 and 21 surgical inpatients respectively. The majority of the Enterobacteriaceae isolates were susceptible to pefloxacin (91 to 100 per cent). The isolates of Acinetobacter spp. and Pseudomonas aeruginosa were less susceptible (77 and 33.3 per cent respectively). The isolates of Staphylococcus aureus and S. epidermidis were mainly susceptible to the drug. The high antimicrobial activity of pefloxacin used therapeutically well correlated with the favourable time course of the main disease. When pefloxacin was used prophylactically the results were positive in all the cases. The drug tolerance in the majority of the cases was good. Only 2 patients developed allergic reactions as multiple minipunctate rash. After discontinuation of the drug use and short-term course of the desensitization the clinical sings of the allergic reactions disappeared in 3 days.

Anti-Infective Agents↗

[Ciprofloxacin in the prevention and treatment of surgical infections].

A clinico-laboratory study on ciprofloxacin made by Bayer (Germany) was applied to patients with extended posttraumatic wounds and performed with the aim of preventing postoperative purulent complications in patients operated on the organs of the gastrointestinal tract. In the both groups ciprofloxacin was administered orally in doses of 500 and 1000 mg and intravenously in a dose of 200 mg. The results of the assay on ciprofloxacin sensitivity of the isolates from the wound excretion and urine showed that they were more sensitive to ciprofloxacin than to aminoglycosides and cephalosporins. 15 minutes after the intravenous administration the serum concentration of ciprofloxacin amounted to 7.5 +/- 0.9 micrograms/ml and in 6 hours it was equal to 0.45 +/- 0.45 micrograms/ml, the mean concentrations of ciprofloxacin being attained in the bile (8.7 +/- +/- 3.9 micrograms/ml), gallbladder wall (5.5 +/- 3.8 micrograms/g), liver (0.73 micrograms/g), muscles (1.93 micrograms/g) and tendon (0.15 microgram/g). After the oral administration in a dose of 500 mg ciprofloxacin was detected in the blood serum in an amount of 2.0 +/- 0.7 micrograms/ml in 1 hour and in an amount of 0.9 +/- 0.13 micrograms/ml in 6 hours. After the drug oral administration in a dose of 1000 mg the maximum concentrations were: 6.34 +/- 4.2 micrograms/ml on the average and 2.1 +/- 0.8 micrograms/ml in 6 hours (0.4 micrograms/g in the muscles, 1.4 micrograms/g in the skin and 0.34 micrograms/g in the bones). The study showed that ciprofloxacin was a highly efficient antimicrobial agent in the treatment of the complicated wound infections and the prophylaxis of the purulent complications during the postoperative period in the patients operated on gastrointestinal organs.
