The use of augmentin (amoxicillin/clavulanate) in the postoperative period in patients with infectious-inflammatory diseases of the ENT organs]

Augmentin (SmithKline Beecham) was used in the treatment of 24 patients after operations on the otorhinolaryngologic organs. The drug was administered orally, intravenously or applied locally. After a radical operation on the maxillary sinus the use of augmentin resulted in a marked decrease of the wound secretion and soft tissue edema on the 6th-7th days. After tonsillectomy cleaning of the tonsil niche from the fibrin patches and the epithelialization started on the 4th-5th days. After operations on the temporal bone cleaning of the postoperative cavity and beginning of the epithelialization were observed on the 9th-10th days. On the whole, the use of augmentin accelerated the cure which was recorded 3-4 days earlier.     

A trial of using augmentin (amoxicillin/clavulanate) in surgical practice]

The experience with the use of augmentin (amoxycillin/clavulane) in abdominal surgery for prophylaxis of postoperative purulent complications was analyzed. The drug was used in 44 patients after relatively pure operations, 37 of them having various risk factors. In 2 patients (4.5 per cent) of that group postoperative pyoinflammatory complications were recorded. For comparison the results of the prophylactic use of cefoperazone, cefamandole or ceftazidime in the group of 78 patients after relatively pure operations on the abdominal cavity organs were analyzed. Postoperative complications in the latter group amounted to 7.4 per cent (4 patients). The results of the treatment of patients in two groups after contaminated operations were also compared. The patients of one group (41 patients) were treated prophylactically with augmentin in a dose of 1200 mg intraoperatively followed by the drug use in a dose of 600 mg thrice daily for 1 to 2 days after the operation. Postoperative pyoinflammatory complications were recorded in 4 patients of that group (9.7 per cent). 78 patients of the other group were treated prophylactically with ceftazidime or cefoperazone in a dose of 2 g and metronidazole intraoperatively or cefoperazone in a dose of 2 g twice daily and metronidazole in a dose of 500 mg twice daily for 1 to 2 days after the operation. Postoperative infectious complications were recorded in 8 patients of that group (10 per cent). In the group of patients with acute cholecystitis treated with ciprofloxacin in a dose of 400 mg in combination, with metronidazole before the operation and for 1 to 2 days after the operation postoperative complications were recorded in 4 patients (17 per cent).     

Ampicillin pharmacokinetics in the lymph and blood in acute inflammatory diseases of the abdominal cavity organs]

Ampicillin levels in the lymph, blood and urine were studied in 15 patients with various inflammatory diseases of the organs of the abdominal cavity. It was found that ampicillin administered intramuscularly to such patients at early postoperative periods was well absorbed not only to the blood but also to the lymph, reaching in parallel its maximum levels in an hour. After that the drug concentration in the lymph persisted for 6 hours and markedly exceeded that in the blood. Adsorption of the lymph lowered the antibiotic concentration in it to 25 per cent indicating the necessity for increasing the drug therapeutic doses.     

A trial of using timentin (ticarcillin/clavulanate) in treating abdominal surgical infection]

Efficacy of timentin was studied in the treatment of 19 patients with peritonitis of various etiology and clinical and laboratory signs of systemic inflammatory reaction characteristic of abdominal sepsis. The clinical and bacteriological effects were recorded in 84.2 and 87.5 per cent of the cases respectively. The drug was administered intravenously dropwise for 30 minutes in a dose of 3.1 g every 4 hours. The treatment course was 4-11 days. The treatment failed in 3 patients. One of them had general peritonitis of gynecological etiology. In the other no significant regression of abdominal sepsis was observed, Pseudomonas aeruginosa strains were isolated from the abdominal cavity, the antibiotic was changed, still incurable polyorganic insufficiency developed and the patient died. The third patient had perforation of the large intestine due to tumor. No adverse reactions to the use of timentin in any of the cases was observed.     

Antibiotic prophylaxis of postoperative suppurative complications in surgical urology

Preoperative sanation of the urinary tracts is an obligatory condition for lowering the risk of severe infectious complications. When there is no bacteriuria it is recommended in the cases subject to short-term surgical interventions without subsequent drainage of the urinary tracts to perform single or one-day prophylaxis with cephalosporins or semi-synthetic penicillins in the routine doses. The same principle is applicable to transurethral operations, endourological manipulations and lithotripsy. When there are urinary fistulas preventing complete sanation of the urinary tracts before operations it is advisable to use combinations of aminoglycosides with carbenicillin. The treatment terms in such cases amount to 7 to 10 days. Antibiotics of the reserve group, i.e. amikacin, sisomicin and ureidopenicillins should not be used prophylactically in such cases.     

Leukinferon in immunological correction of acute inflammatory diseases of the abdominal organs]

Addition of (intramuscular+intravenous) leukinferon (LF) to the schemes for the treatment of acute peritonitis promoted a more rapid positive development of the time course of clinical signs and decreasing of leukocytosis in the presence of a pronounced tendency to normalization of the main immunological indices i. e. the counts of differential T-lymphocytes and T-helper cells. There was also activation of neutrophil phagocytic function. A rapid decrease in objective signs of endotoxicosis was recorded: the intoxication leukocytic index and the level of medium-mass molecules. In parallel with the decrease in the intoxication leukocytic index, there was a decrease in cytosis of the peritoneal exudate. The use of LF in the treatment of elderly patients with acute cholecystitis eliminated the clinical signs and normalized the main laboratory indices without surgical interventions which allowed one to make a planned operation with the minimum risk.     

Antibiotic prophylaxis with amoxicillin/clavulinate (Augmentin) in extended and combined operations in gynecologic cancer patients]

Frequency of postoperation complications at oncological patients deviates in the range from 10 to 70 per cent. The highest frequency of infectious complications is registered after extended and complex operations (cervical carcinoma, cancer of vulva, ovarian cancer). The most frequent aerobic pathogens in oncology are enterococci, staphylococci and streptococci, in the case of urinary tract operations--enterococci and Erscherichia coli. Perioperation prophylaxis with amoxycillin/clavulanate (Augmentin) effective against this microorganisms and also against anaerobic bacteria (usual pathogens of post operation infections in oncogynecology) resulted with lower frequency of wound infections. Demonstrated prophylaxy efficacy was more potent than that of cefotaxime (p < 0.05) or when compared to results of other antibiotics administration after operations only.     

Prevention of infectious complications in patients with acute bone marrow depression]

Clinical efficacy of intravenous gentamicin in combination with oral use of gentamicin, ristomycin and nystatin was studied in 1977. In 1980-1984 two antiinfectious regimens were tested: intravenous administration of gentamicin in combination with total decontamination (oral use of gentamicin and nystatin) and selective decontamination (biseptol with nystatin of amphoglucamine). It was shown that the incidence of severe infections in the patients under the observation dropped against the controls. The incidence and spectrum of infectious complications in cases with acute myelodepressions were proved to depend on the intestinal autoflora inhibition.     

The antibiotic prophylaxis of postoperative complications in breast cancer patients

The studies showed that infectious complications in patients operated for breast cancer (BC) most frequently developed after removal of the drainage tube resulting in poorer discharge favourable for development of infections. The causative agents in such cases are usually exogenous bacteria differing from endogenous ones (Staphylococcus epidermidis) inhabiting the human skin and sometimes contaminating the operative field. The endogenous bacteria are detectable bacteriologically in 60 per cent of the cases. Still, since the operation wound contains humoral and tissue immunity factors (specifically active against the host microflora) such bacteria rarely grow on artificial media (18 per cent) and even more rarely cause infections. Therefore, to prevent postoperative infections in patients with BC it should be recognized rational to use broad-spectrum antibacterial drugs such as ampiox, ampicillin, doxycycline, cephalosporins of the 2nd and 3rd generations, etc. for 5 to 6 days after the drainage removal. If an infection develops the preventive therapy should be replaced by an adequate therapy in accordance with the pathogen sensitivity.     

Cefoperazone in combination with metronidazole in the prevention of postoperative infectious complications in patients with genital neoplasms]

Cefoperazone and metronidazole were used for the prevention of postoperative infectious complications in 33 patients (Group 1) with cervical cancer who had undergone the Wertheim operation. 29 patients (Group 2) were treated prophylactically with carbenicillin in the routine doses. Postoperative urinary infections developed in 12.1 and 37.9 per cent of the patients in Groups 1 and 2, respectively. Since the incidence of infectious complications in the patients of Group 1 was lower, the radiation therapy was initiated on an average on day 12.4 +/- 0.4, which was much earlier than in Group 2 (day 15.4 +/- 0.8, p < 0.001). Bacteriological examination of the operation materials from the patients of Group 1 revealed the presence of anaerobes in 64.3 per cent of the patients. The incidence of fever (over 37.8 degrees C) developed irrespective of other signs of an infection significantly correlated with the detection rate of anaerobes in the operation materials (p < 0.05).     

Problems of prophylaxis and treatment of infectious complications in reconstructive surgery]

Infectious complications due to polyresistant staphylococci as well as strepto- and enterococci are of serious problem in reconstructive surgery, since the number of such strains isolated within 1999-2004 has amounted to 58.4-59.7% of all the isolates. Susceptibility testing of 195 isolates showed that 100% of them was susceptible to linezolid that was used in the postoperative treatment of 28 patients after reconstructive surgical operations including those with artificial circulation under conditions of a multiprofile surgical hospital. Linezolid proved to be a highly effective agent in the prophylaxis and treatment of infectious complications due to polyresistant grampositive pathogens. Step-by-step therapy with linezolid was shown possible. In the treatment of pediatric cases no side effects of linezolid were recorded.     

The efficacy of cefepime (Maxipime) in the treatment of abdominal sepsis in surgical patients]

The efficacy of cefepime in the treatment of 46 patients operated for general peritonitis of various genesis and severity (APACHE II not greater than 35) was studied. Cefepime was used in a dose of 2 g administered every 12 hours as slow intravenous infusions in 0.9 per cent sodium chloride solution in combination with metronidazole administered intravenously in a dose of 7.5 mg/kg body weight. The treatment course was 4 to 15 days. 45 patients were given diflucan for the prophylaxis of fungal superinfection, 3 patients were given aminoglycoside antibiotics (netilmicin or amikacin) and 2 patients were given vancomycin per os. The favourable clinical effect of the cefepime therapy was stated in 38 patients (82.6 per cent) including 4 out of 10 patients with initial APACHE II > 15. 101 isolates of aerobic gram-negative and gram-positive microbes from 38 patients treated with cefepime in combination with metronidazole were tested to estimate the bacteriological efficacy of the therapy and it was shown that only 5.9 per cent of them was resistant. The pathogen eradication was stated in 84.2 per cent of the patients.     

Microbiological monitoring in prophylaxis and treatment of pyoinflammatory complications during early postoperative period in patients with cicatricial tracheostenosis]

The species composition and antibiotic susceptibility of microflora isolated from patients with cicatricial tracheostenosis (CTS) and infectious processes were investigated. Schemes for the treatment of CTS with an account of the pathogen species and multidrug resistant staphylococcal infection are described. Comparative efficacy of the combined schemes (antibiotic + bacteriophage) for the therapy of pyoinflammatory processes in the patients with CTS and the efficacy of the treatment of the patients with CTS according to the traditional antibacterial schemes were studied.
