In the surgical units of our Division, from January 1979 to December 1989, the infection rate in surgical groin hernia repair was much higher than expected, in comparison to other reports in the literature. In order to evaluate if correct preoperative antibiotic prophylaxis could decrease the incidence of postoperative infections (wound, urinary and respiratory tract) after abdominal wall hernia repair surgery, a total of 1,524 consecutive patients undergoing this type of procedure were reviewed between January 1990 and December 1996. The patients were divided in three different groups, according to the antibiotic prophylaxis regimen: i) group A: 606 patients (39.8%) treated with ceftriaxone; ii) group B: 408 patients (26.8%) treated with pefloxacin; and iii) group C: 510 patients (33.4%) treated with different regimens using either cephalosporins or quinolones other than ceftriaxone and pefloxacin. Only 1 surgical wound infection was observed (0.06%). The tolerability was good: no significant side effects related to antibiotic prophylaxis were recorded in our experience. In this study, even though retrospective, single-dose ceftriaxone proved to be a valid and cost-effective choice in antibiotic prophylaxis. 相似文献

The aim of the study was to evaluate the effect of two different regimens of antibiotic prophylaxis in colorectal surgery. The study comprises 57 consecutive cases. The mechanical preoperative preparation was essentially the same in all cases and the operative technique was standardized as far as possible. Antibiotic prophylaxis was started immediately before surgery and continued for three days postoperatively. Thirty-six patients received doxycycline 200 mg i.v. per day and 21 patients were given benzylpenicillin 10 million I.U. 4 times a day and streptomycin 500 mg twice a day. No major infectious complications (e.g. septicaemia, abscessess) were seen in either group. There were three wound infections in the doxycycline group and four in the penicillin-streptomycin group. 相似文献

The efficacy and safety of single-dose ceftriaxone and multiple-dose cefuroxime as antibiotic prophylaxis for pleuropulmonary surgery were compared in 160 patients undergoing thoracic surgery. 82 patients received a single-dose of 2 g ceftriaxone intravenous prior to surgery. Seventy-eight patients received 1.5 g of cefuroxime i.v. prior to surgery and 750 mg i.m. every 8 hours for the next 48 hours. Patients were observed daily for ten days postoperatively and monitored for signs of wound and systemic infections. Postoperative infections were studied in each treatment group. No adverse postoperative infections effects or laboratory abnormalities attributable to either drug were noted. Those results indicate that single-dose ceftriaxone was as effective and well-tolerated as a multiple-dose cefuroxime in preventing postoperative infections following pleuropulmonary surgery. 相似文献

Consecutive patients with serious infections were randomized between gentamicin 4 mg/kg once daily i.v. or netilmicin 5.5 mg/kg once daily i.v. (with dosage reduction in case of renal dysfunction). Exclusion criteria were neutropenia or severe renal failure. Median first serum trough and peak concentrations were 0.4/9.5 mg/L and 0.4/12.2 mg/L, for gentamicin and netilmicin respectively. A good clinical response was observed in 50/54 (92.6%) evaluable patients treated with gentamicin and in 48/52 (92.3%) netilmicin-treated patients. Nephrotoxicity (a rise of serum creatinine > or = 45 mumol/L) developed in 5/72 (6.9%) gentamicin patients treated > or = 48 hours and in 10/69 (14.5%) netilmicin patients (difference 7.5%, 95% CI -3.9% to +16.2%). High-tone audiometry was performed when possible; no significant differences were found between the regimens with regard to hearing loss or prodromal signs of ototoxicity. We conclude that with once-daily dosing no benefit of netilmicin over gentamicin regarding nephro- or ototoxicity could be demonstrated. 相似文献

Antimicrobial prophylaxis in colorectal surgery: a systematic review of randomized controlled trials
BACKGROUND: A systematic review was carried out to assess the relative efficacy of antimicrobial prophylaxis for the prevention of postoperative wound infection in patients undergoing colorectal surgery. METHODS: MEDLINE, EMBASE, the Cochrane Trials Register and the references cited in retrieved studies were searched to identify relevant trials published between 1984 and 1995. RESULTS: Some 147 relevant trials were identified. The quality of trials has improved over the past 12 years. The results confirm that the use of antimicrobial prophylaxis is effective for the prevention of surgical wound infection after colorectal surgery. There was no significant difference in the rate of surgical wound infections between many different regimens. However, certain regimens appear to be inadequate (e.g. metronidazole alone, doxycycline alone, piperacillin alone, oral neomycin plus erythromycin on the day before operation). A single dose administered immediately before the operation (or short-term use) is as effective as long-term postoperative antimicrobial prophylaxis (odds ratio 1.17 (95 per cent confidence interval (c.i.) 0.90-1.53)). There is no convincing evidence to suggest that the new-generation cephalosporins are more effective than first-generation cephalosporins (odds ratio 1.07 (95 per cent c.i. 0.54-2.12)). CONCLUSION: Antibiotics selected for prophylaxis in colorectal surgery should be active against both aerobic and anaerobic bacteria. Administration should be timed to make sure that the tissue concentration of antibiotics around the wound area is sufficiently high when bacterial contamination occurs. Guidelines should be developed locally in order to achieve a more cost-effective use of antimicrobial prophylaxis in colorectal surgery. 相似文献

BACKGROUND & AIMS: Antibiotic prophylaxis in severe pancreatitis has recently yielded promising clinical results, with imipenem significantly reducing the incidence of infected necrosis compared with an untreated control group. On the bases of pefloxacin's spectrum of action and pancreatic penetration, we investigated whether such drugs represent a valid alternative to imipenem. METHODS: In a multicenter study, 60 patients with severe acute pancreatitis with necrosis affecting at least 50% of the pancreas were randomly allocated to receive intravenous treatment for 2 weeks with pefloxacin, 400 mg twice daily (30 patients), or imipenem, 500 mg three times daily (30 patients), within 120 hours of onset of symptoms. Age, sex, body weight, Ranson and Apache II scores, C-reactive protein, etiology, and time from onset of symptoms to treatment were well matched in the two groups. RESULTS: The incidences of infected necrosis and extrapancreatic infections were 34% and 44%, respectively, in the pefloxacin group and 10% and 20% in the imipenem group. Imipenem proved significantly more effective in prevention of pancreatic infections (P = 0.05). Mortality was not significantly different in the two groups. CONCLUSIONS: Despite its theoretical potential, pefloxacin is inferior to imipenem in the prevention of infections associated with severe pancreatitis. 相似文献

OBJECTIVE: To evaluate the safety and efficacy of cefepime hydrochloride plus metronidazole vs the combination of imipenem and cilastatin sodium in the treatment of complicated intra-abdominal infections in adult patients. DESIGN: Prospective, randomized, double-blind multicenter study. SETTING: University-affiliated hospitals in the United States and Canada. PATIENTS: Three hundred twenty-three patients with complicated intra-abdominal infections in whom an operative procedure or percutaneous drainage was required for diagnosis and management. INTERVENTION: Cefepime, 2 g, was administered intravenously every 12 hours (n= 164) in addition to metronidazole, 500 mg (or 7.5 mg/kg) intravenously every 6 hours. Imipenen-cilastatin sodium, 500 mg, was administered intravenously every 6 hours (n= 159). Surgical infection management was determined by the patients' surgeons. MAIN OUTCOME ASSESSMENTS: Clinical cure, defined as elimination of all signs and symptoms relevant to the original infection; and treatment failure, defined as persistence, increase or worsening of signs and symptoms resulting in an antibiotic change, requirement of an additional surgical procedure to cure the infection, or a wound infection with fever. RESULTS: Of the initial isolates, 84% were susceptible to cefepime and 92% were susceptible to imipenem-cilastatin. Among the 217 protocol-valid patients, those treated with cefepime+metronidizole were deemed clinical cures (88%) more frequently than were imipenem-cilastatin-treated patients (76%) (P=.02). Using multivariate analysis to adjust for identified clinical risk factors for an adverse outcome (severity of presenting illness, isolation of enterococcus, type of infection, and duration of prestudy hospitalization), there was a trend (P=.06) toward a higher cure rate favoring cefepime+metronidazole. Pathogens were eradicated in significantly (P=.01) more patients treated with combined cefepime and metronidazole (89%) than with imipenem-cilastatin (76%). CONCLUSION: The combination of cefepime plus metronidazole is safe and effective therapy for patients with severe intra-abdominal infections. 相似文献

The purpose of this work was to compare the efficacy and safety of the collagen-gentamicin sponge with conventional treatment (wound open, maintaining a close observation, and cleaning it daily with antiseptics) for the prophylaxis of infection in "dirty" abdominal wounds. Seventy-three patients with dirty abdominal wounds caused by gastrointestinal tract surgery were studied. The patients were randomized in two groups: group A, open wounds, treated with local cleansing, metronidazole 20 to 40 mg/kg/day IV and gentamicin 5 mg/kg/day IV for 7 days. Group B, primary closure with collagen-gentamicin implant plus metronidazole 20 to 40 mg/kg/day IV for 7 days. Surgical wound infections were significantly reduced by the collagen-gentamicin implant. Polymicrobial infections were observed in group A, whereas the infections were caused only by a single organism in group B. In conclusion, the collagen-gentamicin implant is effective and well tolerated in the treatment of "dirty" surgical abdominal wounds because it significantly reduces the wound infection rate (p < 0.01) and shortens healing time (p < 0.001) and the period of disability. 相似文献

OBJECTIVES: To determine whether a combination of ciprofloxacin hydrochloride and metronidazole hydrochloride would be as effective or more effective than a combination of gentamicin sulfate and metronidazole hydrochloride for preventing infection in patients with penetrating abdominal trauma, to evaluate the factors associated with increased risk of infection, and to determine the serum peak and trough levels of gentamicin with the dosage regimen of 2.5 mg/kg every 12 hours. DESIGN: Randomized double-blind study. SETTING: Level I trauma center. PATIENTS: Eighty-four patients with penetrating intra-abdominal injuries (gunshot wound, 69; stab wound, 15) thought to require laparotomy. INTERVENTIONS: The patients were randomized during treatment in the emergency department to be given a combination of ciprofloxacin hydrochloride, 400 mg every 12 hours, and metronidazole hydrochloride, 500 mg every 6 hours, or a combination of gentamicin sulfate, 2.5 mg/kg every 12 hours, and metronidazole hydrochloride, 500 mg every 6 hours. RESULTS: Of 68 patients with intra-abdominal injuries who could be observed for at least 48 hours after laparotomy, posttraumatic infections developed in 12 (18%), and nosocomial infections developed in 6 (9%). The incidence of posttraumatic infections in patients who were given gentamicin and metronidazole (5/33 [15%]) was not significantly lower than the incidence in patients who were given ciprofloxacin and metronidazole (7 of 35 [20%]; P=.75). The presence of any infection increased the mean+/-SD length of hospital stay from 8.7+/-3.5 days to 23.3+/-10.9 days and increased the mean+/-SD hospital charges from $24 507+/-$9860 to $104920+/-$49083 (P<.001). Univariate analysis showed the factors most significantly associated with infection were as follows: (1) the use of blood transfusions (P<.001), (2) the penetrating abdominal trauma index of 35 or more (P<.002), (3) injury to the colon requiring a colostomy (P=.004), and (4) a trauma score of less than 12 (P<.02). Multivariate analysis showed the only significant factor was the receipt of blood transfusions (F=10.165; P<.005). CONCLUSIONS: Ciprofloxacin and gentamicin, each in combination with metronidazole, were equivalent in their ability to prevent infections after penetrating abdominal trauma; other factors, especially the receipt of blood transfusions, had much more effect on the incidence of infection. Infection greatly increases the length of hospital stay and hospital charges. The use of an increased dosing regimen of 2.5 mg/kg every 12 hours of gentamicin sulfate was effective at obtaining a therapeutic peak serum concentration. 相似文献

METHODS: In a randomized double-blind study, 134 patients were given 500 mg metronidazole as an intravenous infusion immediately before operation for abdominal total hysterectomy and again 8 hours later and 124 patients received placebo. RESULTS: There was more wound infection, postoperative hospitalization was longer and the sedimentation rate on the sixth postoperative day was significantly higher in the placebo group. There was no difference in postoperative temperature. Postoperative wound infections occurred in 12% in the placebo group and 6% in the metronidazole group. Eight percent in the total material had urinary tract infections, the diagnosis was based on urine cultures. CONCLUSIONS: Prophylaxis with intravenous infusion of metronidazole is recommended in total hysterectomies. 相似文献

The purpose of the study reported here was to investigate the impact of prophylaxis against gram-positive infections in patients undergoing high-dose chemotherapy and autologous bone marrow transplantation in a randomized trial. Forty-three patients undergoing high-dose chemotherapy with autologous bone marrow transplant were enrolled in a nonblinded randomized trial to receive or not to receive prophylaxis for gram-positive infections with 10(6) U of penicillin intravenously (i.v.) every 6 h (q6h) (if penicillin allergic, 750 mg of vancomycin i.v. q12h) in addition to standard antimicrobial prophylaxis with 400 mg of norfloxacin orally three times a day, 200 mg of fluconazole orally once a day, and 5 mg of acyclovir per kg of body weight i.v. q12h. The patients were being treated for germ cell cancer (n = 15), breast cancer (n = 16), Hodgkin's disease (n = 3), non-Hodgkin's lymphoma (n = 4), acute myeloid leukemia (n = 1), acute lymphoblastic leukemia (n = 1), and ovarian cancer (n = 3). The trial was stopped because of excess morbidity in the form of streptococcal septic shock in the group not receiving gram-positive prophylaxis. There were significantly fewer overall infections (10 versus 3; P = 0.016) and streptococcal infections (9 versus 1; P = 0.0078) in the group receiving gram-positive prophylaxis. There were no significant differences in the numbers of deaths, duration of broad-spectrum antibiotics, or incidence of neutropenic fever between the two groups. Prophylaxis for gram-positive infections with penicillin or vancomycin is effective in reducing the incidence of streptococcal infections in patients undergoing high-dose chemotherapy and autologous bone marrow transplant. However, this approach may carry a risk of fostering resistance among streptococci to penicillin or vancomycin. 相似文献

The prophylactic effect of a intraoperative intraperitoneal and subcutaneous application of cefazolin versus a single shot i.v. prophylaxis was investigated. Additionally, we registered the concentration of cefazolin in the serum and the peritoneal fluid in 22 patients. We randomized 200 patients of whom 189 were included in the study. Ninety-two patients received the prophylaxis i.v. (group 1) and 97 topically (group 2). In 4 (2.1%) wound infections occurred [3(3.3%) group 1 and 1 (1.0%) in group 2]. The difference was not significant. The concentration of cefazolin in the serum was significantly higher at 1 h and 2 h postoperatively in group 2. We conclude that a topical application of antibiotics is possible to prevent surgical wound infection. 相似文献

We report a prospective, controlled study of the incidence of septic complications following biliary tract stone surgery. This study included a total of 280 patients operated on in eight hospitals in various European countries. In this study the computer program "Surgery" was used. Of 280 patients, 77 (27.5%) were male and 203 (72.5%) were female. The age ranged from 20 to 92 years (mean 54.8 years); 78.9% of the cases corresponded to clean-contaminated surgery; 85% of the patients received antibiotic prophylaxis with cefazolin. Twenty-one patients developed postoperative septic complications (7.5%) of which 12 (4.3%) were wound infections; five patients (1.8%) had intra-abdominal infections. The wound infection rate was 3.2% in clean-contaminated surgery, 7.7% in contaminated and 20% in dirty (p < 0.02). In laparoscopic cholecystectomy the global rate of septic complications was 3.6% vs. 12.6% in open cholecystectomy (p < 0.01); 2.4% and 6.3% wound infection respectively. The mean age of patients who developed postoperative septic complications was 61.5 years and 54.2 years old who did not develop any complications (p < 0.03). The duration of the postoperative period was 5 days in patients without infection and 13 days in patients with infection (p < 0.0001). Two patients died, one of them (0.4%) caused by sepsis. In addition to the European prospective study, a review of the problems of sepsis in biliary surgery was carried out. 相似文献

In North America, the rate of infections following colorectal surgery decreased after the introduction of oral antibiotic bowel preparation against colonic microflora. Eight hundred eight board-certified colorectal surgeons were surveyed for their current bowel preparation practices before elective procedures. The 471 responders (58%) all use mechanical preparation: oral polyethylene glycol solution (70.9% of the respondents), oral sodium phosphate solution with or without bisacodyl (28.4%), and "traditional" methods of dietary restriction, cathartics, and enemas (28.4%). Most surgeons (86.5%) add oral and parenteral antibiotics to the regimen; 11.5% add only parenteral antibiotics, 1.1% add only oral antibiotics, and 0.9% add no antibiotics. Generally (77.8% of cases), oral neomycin and erythromycin or metronidazole are combined with a perioperative parenteral antibiotic. Most individuals start the preparation as outpatients the day before surgery, and the parenteral drugs are added to the regimen 1-2 hours before the procedure. The use of outpatient bowel preparation is increasing; however, patient selection is critical, and education is needed to reduce the rate of complications. 相似文献

Continuous intravenous infusion (c.v.i.) of 5-fluorouracil (5-FU) plus daily low-dose cisplatin (CDDP) was evaluated in 45 patients with advanced and recurrent unresected colorectal, lung, gastric and pancreatic adenocarcinoma. 5-FU was given at a dose of 320 mg/m2/day, c.v.i. for 4 weeks, and CDDP between 3.5 to 7 mg/m2/day, infused for one hour five times a week for 4 weeks. Patients received 1 to 3 cycles of treatment (average 1.5 cycle). Pancreatic cancer cases needed longer treatment periods (2.25 cycles). The response rate of colorectal cancer cases was 57.7% (15/26), pancreas cancer 40%, gastric cancer 62.5%, and lung cancer 66.7%. The overall response rate was 57.8%. No severe side effects occurred in any of these cases. These data indicate that this combination 5-FU + daily low-dose CDDP chemotherapy is effective in the treatment of advanced gastrointestinal and lung adenocarcinoma. 相似文献

PURPOSE: To describe the incidence of acute neurotoxicity (NT) in children with lower risk B-precursor acute lymphoid leukemia (ALL) treated with intermediate-dose methotrexate (MTX) or divided dose oral MTX with or without intravenous (i.v.) mercaptopurine (MP) and extended intrathecal triple therapy. PATIENTS AND METHODS: Thirteen hundred four patients were entered onto Pediatric Oncology Group (POG) 9005, a randomized phase III trial, between January 11, 1991 and September 1, 1994. After remission induction, patients were randomized to one of three 24-week intensification schedules: regimen A, MTX 1,000 mg/m2 i.v. infused over 24 hours and MP 1,000 mg/m2 i.v. infused over 6 hours; regimen B, low-dose repetitive MTX 30 mg/m2 orally every 6 hours for six doses and i.v. MP; or regimen C, i.v. MTX alone. Intensification was given every 2 weeks for 12 courses. CNS prophylaxis was age-adjusted intrathecal MTX (ITM). In August 1992, the CNS prophylaxis was changed to age-adjusted triple intrathecal therapy (TIT). Reports of grades 3 and 4 acute NT were reviewed. RESULTS: Acute NT was reported in 95 of 1,218 (7.8%) eligible patients treated on POG 9005. The incidence by regimen was regimen A, 46 of 543 patients (8.3%); regimen B, 13 of 354 patients (3.7%); and regimen C, 36 of 321 patients (11.2%) (P < .001). The majority of events were seizures and the median number of days to first occurrence of symptomatic NT after ITM or TIT was 10 to 11 days. Computed tomography (CT) or magnetic resonance imaging (MRI) evidence consistent with leukoencephalopathy (LE), with or without the presence of cerebral calcifications, was observed in 75% and 77.1 % of symptomatic patients treated on regimens A and C, respectively, but in only 15.4% of symptomatic patients treated on regimen B (P < .001). Factors associated with an increased incidence of NT included increased cumulative exposure with repeated i.v. MTX (regimens A and C v B), increased MTX-leucovorin (LCV) ratio (regimens A and C v B), and choice and timing of TIT therapy. The use of i.v. MP during intensification did not appear to contribute to these complications. The switch to TIT CNS prophylaxis was associated with an inferior overall 4-year continuous complete remission (CCR) (P=.031) when compared with ITM. CONCLUSION: Intensification with repeated i.v. MTX in the setting of low-dose LCV rescue was associated with a higher risk for acute NT and LE, especially in patients who received concomitant TIT. The long-term consequences for affected patients remain unknown. 相似文献

MATERIALS AND METHODS: In the period 1986-1994, 2950 patients with cardiovascular diseases were surgically treated. In 2104 cases we placed biological or synthetic grafts to maintain vascular continuity. The most common has turned out to be abdominal aortic aneurysm. We treated 783 cases in emergency conditions. Staging and localization of infection has been the first aim in patients with synthetic vascular grafts. We studied signs and symptoms related to infections. In all cases we discovered the microorganism responsible of infection we started antibiotic therapy. RESULTS: Surgical infection incidence is 4.9% (154 cases). Series analysis has evidenced a decrease in infection incidence in the period 1986-1994. The most frequent infections are: the urinary tract infection (59 cases, 38.5%) followed by surgical wound infection (37 cases, 24.1%), respiratory tract infection (27 cases, 17.5%), vascular graft infection (23 cases, 14.4%). All patients underwent a preoperative antibiotic prophylaxis with 2 degrees-3 degrees generation cephalosporines. We noted a higher graft infection incidence in patients treated with aortobifemoral reconstruction. We handled surgical infection following two main directions: 1-antibiotic therapy, 2-surgical treatment and antibiotic therapy. CONCLUSIONS: We noted surgical technique improvement and correct application of an antibiotic prophylaxis form has turned out to be the "gold standard" in order to reduce cardiovascular surgical infections. To reduce sepsis or graft infection we can work on either of the following: 1) antibiotic therapy; 2) operative time reduction; 3) try to limit vascular surgery in case of concomitant gastrointestinal surgical disease; 4) using alloplastic vascular grafts with high biological compliance; 5) patency time reduction of invasive diagnostic technique. 相似文献

BACKGROUND: Measurements of prothrombin fragment 1+2 (F1+2), thrombin antithrombin III complexes (TAT) and D-dimer plasma levels have been proposed as non-invasive screening tests to exclude postoperative deep venous thrombosis (DVT). We investigated the diagnostic efficacy of these coagulation activation markers to rule out postoperative DVT in patients undergoing hip surgery under antithrombotic prophylaxis. METHODS: In this substudy of a randomized double-blind thrombosis prophylaxis trial comparing three doses of desirudin (10, 15 or 20 mg b.i.d.) with unfractionated heparin (5000 IU t.i.d.) we used ELISA procedures to measure F1+2, TAT and D-dimer in 159 patients undergoing total hip replacement at baseline (day 0) and on postoperative days 1, 3 and 6. Bilateral venography was performed in all cases 8-11 days after surgery. RESULTS: For the F1+2 assay sensitivity ranged from 73 to 83% in the three postoperative days investigated, and negative predictive value (NPV) from 68 to 74%. For TAT and D-dimer sensitivity ranged from 71 to 73% and from 71 to 83% and NPV from 61 to 65% and from 61 to 74% respectively. INTERPRETATION: In terms of sensitivity and NPV F1+2 and D-dimer are equivalent and are superior to TAT. However, their accuracy is too low to rule out the presence of DVT after hip surgery under antithrombotic prophylaxis. 相似文献

The results of treatment of 23 patients with pefloxacin, administered because of the infectional complications in surgery development (1 group), and of 11 patients --for the infection development prophylaxis (2 group) were discussed. In the first group the recovery was noted in 83.3%, and significant improvement of condition--in 16.7% of patients. In the second group the infectional complications in postoperative period were absent. 相似文献
