Effectiveness of infection prevention with latamoxef in vaginal hysterectomy. A prospective study

A prospective clinical trial was designed to examine the influence of a single-dose prophylaxis with 2 g Latamoxef on postoperative infectious morbidity in women undergoing vaginal hysterectomy. 91 vaginal hysterectomies with latamoxef prophylaxis were compared with a similar group of 99 patients without prophylaxis. Patients in the latamoxef group had significantly less postoperative infectious morbidity (23.1%) than those in the non prophylaxis group (45.1%). Prophylactic latamoxef reduced postoperative additional antibiotic therapy in the prophylaxis group significantly. The postoperative infectious morbidity (urinary tract infections, pelvic infections, febrile morbidity) was significantly reduced by a single-dose prophylaxis with 2 g Latamoxef.     

Postoperative infections and antibiotic prophylaxis in radical hysterectomy. Review of the literature]

Postoperative infectious complications are a frequent cause of morbidity and mortality in the surgical patient. The septic events usually involve the urinary or respiratory tracts or occur at the operative site. The incidence depends on the surgeon's experience, the surgical procedure applied and the clinical status of the patient. Radical hysterectomy with pelvic lymphadenectomy is associated with a high risk of postoperative infections. Factors that influence the risk are prolonged preoperative hospitalization, duration of operation, younger age, obesity, estimated blood loss and lack of antibiotic prophylaxis. Appropriate administration of prophylactic antibiotics requires awareness of the following considerations: the choice of antibiotic agent, the dosage and the timing of administration for maximum benefit without adverse effects. In this review we evaluate the results of studies that use different regimens of antibiotic prophylaxis for prevention of infectious morbidity after radical hysterectomy.     

Local prevention of infection with metronidazole before vaginal hysterectomy--comparative effect compared with systemic prevention?]

A prospective clinical trial was designed to examine the influence of a local intravaginal application of metronidazole on postoperative infectious morbidity in 114 women undergoing vaginal hysterectomy. On the evening before vaginal hysterectomy, 51 patients received a vaginal suppository of metronidazole (500 mg). These patients were compared with a group of 63 patients who were given a single-shot prophylaxis with 1,500 mg cefuroxime intravenously. With regard to febrile morbidity, urinary tract infection and pelvic infection there was no significant difference in the two treatment groups. There was no statistically significant difference in the postoperative duration of hospital stay and additional antibiotic therapy between the two groups either. We did not see serious infections in our examination. Our results suggest that a local single-dose application of metronidazole in vaginal hysterectomy might have the same efficacy on postoperative infectious morbidity than a systemic antibiotic prophylaxis and that it can reduce antibiotic costs.     

Antibiotic prevention of infections complicating radical abdominal hysterectomy

In this randomized, double-blind study, the effectiveness of a single-agent prophylactic antibiotic in reducing infections after radical abdominal hysterectomy with pelvic and para-aortic lymphadenectomy was compared with a placebo. A total of 12 doses of cefoxitin (2g) or placebo were given to 70 patients, starting the evening before surgery. Because of tumor spread beyond the cervix, radical hysterectomy was not performed in 17 patients who were, therefore, excluded from the study. Analysis of 53 patients who completed the study revealed that 15% of cefoxitin patients had surgical site-related infections compared with 52% of placebo patients (P = .005). Significant differences between the groups were also observed in nonsurgical site-related infections (23 versus 48%), overall morbidity (58 versus 89%), and the need for additional antibiotic therapy (38 versus 67%). Socioeconomic status was a significant risk factor with 57% of staff patients demonstrating increased site-related infections as compared with 17% of private patients (P = .002). No clinically significant side effects were observed. The authors recommend the use of antibiotic prophylaxis in patients undergoing radical abdominal hysterectomy for gynecologic malignancies.     

Comparative efficacy of short-term versus long-term cefoxitin prophylaxis against postoperative infection after radical hysterectomy: a prospective study

We report the results of a randomized, double-blind comparison of short-term versus long-term cefoxitin prophylaxis against infections after radical abdominal hysterectomy with pelvic and para-aortic lymphadenectomy. Of 113 evaluable patients, 54 (47.8%) received short-term (three doses) and 59 (52.2%) long-term (12 doses) prophylaxis with intravenous cefoxitin (2 g per dose). No significant differences in demographics, preoperative risk factors, or clinical course were detected between the two groups; nor did we detect significant differences in the incidence of surgical-site-related infections (7.4 versus 5.1%, respectively, P = .61), postoperative urinary tract infection, or other febrile morbidity. We conclude that short-term and long-term cefoxitin prophylaxis are equally effective for the prevention of post-operative surgical-site-related infections after radical hysterectomy.     

Prophylactic antibiotic administration prior to hysterectomy: a quality improvement initiative

OBJECTIVE: To determine whether institution of a preoperative antibiotic policy could increase the use of prophylactic antibiotics prior to hysterectomy. STUDY DESIGN: A retrospective cohort study of 400 women who underwent abdominal, vaginal or laparoscopic hysterectomy for benign indications at Women and Infants Hospital was performed. Rates and timing of prophylactic preoperative antibiotic administration were determined, as were the rates of postoperative febrile morbidity. These data were compared to data collected in a medical record review of 686 hysterectomies performed prior to institution of the antibiotic policy. RESULTS: Prior to the institution of the antibiotic policy, 50% of patients (342/686, 95% CI 46.0, 53.7) received prophylactic preoperative antibiotics. After introduction of the antibiotic policy, 91.2% (95% CI 88.0, 93.8) of patients received prophylactic preoperative antibiotics. Approximately 66% of the antibiotics were administered within the 60 minutes preceding the surgical incision. Postoperative febrile morbidity was noted in 14% of patients prior to the antibiotic policy as compared to 11% of patients after the policy was instituted. Abdominal surgical approach was found to be a clinically and statistically significant risk factor for febrile morbidity (OR = 7.0; 95% CI 2.3, 20.9). CONCLUSION: Rates of prophylactic preoperative antibiotic administration significantly increased after institution of a hospital policy advocating routine antibiotic prophylaxis prior to hysterectomy. Additional steps must be taken to ensure more routine and appropriately timed administration of antibiotics prior to hysterectomy and to continuously monitor the use of prophylactic antibiotics.     

Infection after radical abdominal hysterectomy and pelvic lymphadenectomy: prevention of infection with a two-dose peri-operative antibiotic prophylaxis

Surgical site-related infections occurred in 21% of 87 consecutive patients undergoing radical hysterectomy with pelvic lymphadenectomy (RHPL) without planned peri-operative prophylaxis. A prospective, randomized double-blind, placebo-controlled study was conducted in 68 consecutive RHPL patients. In the 32 available patients with two-dose cefuroxime and metronidazole prophylaxis no surgical site-related infections developed as opposed to a rate of 14% in the 28 patients in the placebo group ( P < 0.05). In a prospective, randomized double-blind study two two-dose antibiotic prophylactic regimens were compared in 105 consecutive patients. Surgical site-related infections developed in one (2%) patient in the cefuroxime plus metronidazole group, and in six (12%) patients in the moxalactam group. This difference did not achieve statistical significance. The mean length of the postoperative hospital stay of the patients with scheduled surgical prophylaxis was significantly shorter ( P < 0.01) than that of the patients operated on without surgical prophylaxis. A two-dose antibiotic regimen is recommended, because levels of antibiotics assayed in samples collected during the course of the operation indicated a rapid clearance of the antibiotics from the operative site, most likely due to the high volume of peri-operative blood loss.     

Prevention of postoperative complications following vaginal hysterectomy

In a prospective study on infectious morbidity after vaginal hysterectomy we examined the clinical symptoms of an infection and partly also the microbial conditions of the vaginal wound. With a group of 49 patients without antibiotic prophylaxis we tried to find out if the type of vaginal occlusion might have any influence on the microbial situation and the healing process. The results of this first group were compared to those of a second group consisting of 31 patients, who had received antibiotic prophylaxis before the operation with a cephalosporin. Though it was not possible to make any microbial analyses in the second group, the clinical evaluation showed distinctly that antibiotic prophylaxis is an important contribution to the prevention of infections after vaginal hysterectomy. The careful consideration of septic-surgical precautions, however, and this was proved by the first part of the study, contributes as well to the prevention of infections.     

Effectiveness of perioperative preventive use of antibiotics with metronidazole or doxycycline in vaginal hysterectomy

To prove the effectiveness of perioperative antibiotics prophylaxis (PABP) in prevention of postoperative infections after vaginal hysterectomy the efficacy of rectale Metronidazole application (5 times 500 mg; n = 192) was compared with that of Doxycyclin (2 times 200 mg intravenously; n = 116). The infectious morbidity after both prophylactic antibiotic regimes was compared to that of an untreated group (n = 186). In spite of additionally colporrhapies the feverish standard morbidity without prophylaxis was 13.4%, after Metronidazole application 13.5% and after Doxycyclin 2.6% (p less than 0.05). Simultaneously the rate of necessary antibiotic treatment decreased significantly. Pelvic infections complicated 16.7% of vaginal hysterectomies having no prophylaxis, but only 4.3% after Doxycyclin medication (p less than 0.05). Postoperative urinary tract infections (UTI)--mostly asymptomatic bacteriuria--were not influenced by any PABP. Whereas UTI after bladder catheter duration shorter than two days occurred in 26.0% (without PABP), 29.9% (Metronidazole) respectively 18.2% (Doxycyclin; p greater than 0.05), the rates after a longer stay were 69.6%, 76.8% and 65.7%. It is concluded, that the febrile standard morbidity and pelvic infections were reduced as well as the rate of necessary antibiotics therapies by a prophylactic application of Doxycyclin, but not with Metronidazole. The incidence of postoperative UTI was not reduced by prophylaxis.     

Postoperative infections and antibiotic prophylaxis for hysterectomy in Sweden: a study by the Swedish National Register for Gynecologic Surgery

AIM: The purpose of the study was to evaluate the current use of antibiotic prophylaxis, the rate of postoperative infections, and risk factors for postoperative infections in patients undergoing elective hysterectomy for non-malignant pathology. METHODS: The study was performed during the time period July 2000 to 1 January 1 2003, using data from the Swedish National Register for Gynecologic Surgery, covering 26 of 49 clinics and approximately 50% of the Swedish population. During this time period, 3267 women undergoing elective hysterectomy for non-malignant pathology (mainly dysfunctional bleeding and fibromas) and with complete data on the use of antibiotic prophylaxis and postoperative follow up were included. A postoperative infection was considered to have developed if patients or the physician reported an infection related to the surgical site, together with reported use of antibiotic treatment. RESULTS: Among the 3267 patients, 341 (10.4%) were considered to have developed a postoperative infection. In cases where antibiotic prophylaxis had not been given, total abdominal hysterectomies and vaginal hysterectomies were associated with the highest frequency for postoperative infections P < 0.05 and P < 0.01, respectively. Notably, also women undergoing subtotal hysterectomy reported significantly lower rates of postoperative infections if prophylactic antibiotics had been given, P < 0.05. Risk factors for postoperative infection were non-use of antibiotic prophylaxis, hospital, age less than 40 years, and BMI > 30 kg/m(2). CONCLUSIONS: The study results have indicated the need of prospective clinical trials on antibiotic prophylaxis for patients undergoing supravaginal abdominal hysterectomy. Also, a need to further evaluate the current prophylactic antibiotic protocols used for obese patients and younger women undergoing any kind of hysterectomy is warranted.     

Comparison of total laparoscopic and abdominal radical hysterectomy for patients with early-stage cervical cancer

OBJECTIVE: To compare intraoperative, pathologic, and postoperative outcomes of total laparoscopic radical hysterectomy with abdominal radical hysterectomy and pelvic lymphadenectomy for women with early-stage cervical cancer. METHODS: We reviewed all patients who underwent total laparoscopic radical hysterectomy or abdominal radical hysterectomy and pelvic lymphadenectomy between 2004 and 2006. RESULTS: Fifty-four patients underwent abdominal radical hysterectomy, and 35 underwent total laparoscopic radical hysterectomy. Mean age was 41.8 years, and mean body mass index 28.1. There was no difference in demographic or tumor factors between the two groups. Mean estimated blood loss was 548 mL with abdominal radical hysterectomy compared with 319 mL with total laparoscopic radical hysterectomy (P=.009), and 15% of patients who underwent abdominal radical hysterectomy required a blood transfusion compared with 11% who underwent total laparoscopic radical hysterectomy (P=.62). Mean operative time was 307 minutes for abdominal radical hysterectomy compared with 344 minutes for total laparoscopic radical hysterectomy (P=.03). On pathologic examination, there was no significant difference in the amount of parametrial tissue, vaginal cuff, or negative margins obtained. A mean 19 pelvic nodes were obtained during abdominal radical hysterectomy compared with 14 during total laparoscopic radical hysterectomy (P=.001). The median duration of hospital stay was significantly shorter for total laparoscopic radical hysterectomy (2.0 compared with 5.0 days, P<.001). For abdominal radical hysterectomy, 53% of patients experienced postoperative infectious morbidity compared with 18% for total laparoscopic radical hysterectomy (P=.001). There was no difference in postoperative noninfectious morbidity. There was no difference in return of urinary function. CONCLUSION: Total laparoscopic radical hysterectomy reduces operative blood loss, postoperative infectious morbidity, and postoperative length of stay without sacrificing the size of radical hysterectomy specimen margins; however, total laparoscopic radical hysterectomy is associated with increased operative time.     

Prophylactic antibiotics in gynecologic surgery.

A 2-year prospective double-blind study of prophylactic antibiotics in 317 patients undergoing elective total abdominal or vaginal hysterectomy was conducted. Patients randomly received placebo, penicillin, or cefazolin 30 minutes prior to surgery and at 6-hour intervals thereafter for 48 hours. Rigid criteria for postoperative morbidity were established. Vaginal hysterectomy patients given either penicillin or cefazolin prophylaxis had fewer postoperative infections (P less than 0.01) compared to those given placebo. A similar trend was noted among women undergoing abdominal hysterectomy; however, this trend was not statistically significant (P greater than 0.05). Despite continuous surveillance, no change in nosocomial flora or antibiotic sensitivity of bacterial isolates was noted. Adverse drug effects and antibiotic-resistant secondary infections were encountered with similar frequency in all treatment groups.     

The effect of a short-term course of antibiotic prophylaxis on patients undergoing total abdominal hysterectomy

A prospective double-blind study of antibiotic prophylaxis in 69 patients undergoing total abdominal hysterectomy was conducted. A short, 1-day course of cefazolin prophylaxis effectively decreased febrile morbidity, serious postoperative infections and hospital stay. Resistant infections or delayed infections were not encountered in this series of prophylactically treated patients. There was no difference between the active drug group and the placebo group in the frequency with which aerobic Gram-negative rods and the incidence of cephalosporin-resistant organisms cultured postoperatively.     

Infectious morbidity after radical vulvectomy

Objective: This retrospective investigation describes the infectious morbidity of patients following radical vulvectomy with or without inguinal lymph node dissection.Methods: The charts of patients undergoing radical vulvectomy between January 1, 1986, and September 1, 1989, were reviewed for age, weight, cancer type, tumor stage, operative procedure(s), prophylactic antibiotic and its length of use, febrile morbidity, infection site, culture results, significant medical history, and length of use and number of drains or catheters used.Results: The study group was composed of 61 patients, 14 of whom underwent a radical vulvectomy and 47 who also had inguinal lymph node dissection performed. Twenty-nine patients (48%) had at least 1 postoperative infection. Five patients (8%) had 2 or more postoperative infections. The site and incidence of the infections were as follows: urinary tract 23%, wound 23%, lymphocyst 3%, lymphatics (lymphangitis) 5%, and bowel (pseudomembranous colitis) 3%. The most common pathogens isolated from both urine and wound sites were Pseudomonas aeruginosa, enterococcus, and Escherichia coli. A significant decrease in wound infection was demonstrated when separate incisions were made for inguinal lymph node dissection (P <0.05). The mean number of days to onset of postoperative infection for wound, urine, lymphatics, lymphocyst, and bowel were 11, 8, 57, 48, and 5, respectively.Conclusions: We conclude that the clinical appearance of post-radical vulvectomy infections is delayed when compared with other post-surgical wound infections. Second, utilizing separate inguinal surgical incisions may reduce infectious morbidity. Finally, tumor stage and type do not necessarily increase the infectious morbidity of radical vulvar surgery.     

Antibiotic prophylaxis for radical abdominal hysterectomy

Records of 35 patients with cervical cancer Stage IB operated with radical abdominal hysterectomy and pelvic lymphadenectomy were surveyed retrospectively for incidence of febrile morbidity and site-related infections. Febrile morbidity was observed in 6 patients (17%). No surgical site-related infections were observed. It is concluded that radical abdominal hysterectomy in our hospital does not carry any significant risk of postoperative site-related infections and that prophylactic antibiotics cannot be recommended.     

Controlled, comparative study of moxalactam and cefazolin for prophylaxis of abdominal hysterectomy

Moxalactam was compared with cefazolin and a control group to determine the efficacy and value of a third generation cephalosporin in abdominal hysterectomy antibiotic prophylaxis. One hundred patients were prospectively randomized in a double-blind manner between moxalactam and cefazolin. An additional 50 patients who were either allergic to penicillin or refused participation in this study were simultaneously observed to establish a base line level of infection on our service during this time period. Dosage for both antibiotic groups was 1 gram given intravenously or intramuscularly on call to the operating room followed by two 1 gram doses at six and 12 hours after the first dose. Standard febrile morbidity was 36, 30 and 42 per cent for moxalactam, cefazolin and control groups, respectively. Postoperative surgical infection requiring antibiotic treatment occurred in 8, 6 and 4 per cent, respectively; urinary tract infection or symptomatic findings, or both, requiring treatment occurred in 8, 10 and 10 per cent, respectively. No pelvic abscesses occurred in this series. In every statistical evaluation of postoperative morbidity, there were no differences noted among the three groups. Our results suggest no benefit from the use of prophylactic antibiotics in abdominal hysterectomy in terms of standard febrile or infectious morbidity or urinary tract pathologic findings. In addition, there was no difference between the two antibiotic groups.     

Preoperative hot conization of the cervix: a possible method to reduce postoperative febrile morbidity following vaginal hysterectomy.

Laboratory results indicate that the endocervix may be a source of bacterial contamination when vaginal hysterectomy is performed. In a series of 160 consecutive vaginal hysterectomies in premenopausal women, hot conization of the cervix was performed prior to the scrub with an iodophore. No preoperative antibiotics were used in this series. The postoperative febrile morbidity rate was 4.3 per cent and the average stay was 4.5 days. These results are compared with those of three other groups: (1) patients who received a three-dose parenteral prophylactic antibiotic course with the first dose two hours prior to surgery had a febrile morbidity rate of 8.6 per cent. (2) In patients who had prophylactic antibiotics for five days with the first dose given intraoperatively, the febrile morbidity rate was 10.1 per cent. (3) The febrile morbidity rate in the group with no antibiotic prophylaxis or hot conization was 49.1 per cent. Laboratory and clinical data suggest that preoperative conization may be effective in the reduction of postoperative febrile morbidity.     

Initial results of perioperative antibiotic premedication with halospor and gentamycin in cesarean section

The perioperative application of antibiotics in prophylaxis of infections is disputed. In a preliminary prospective study the infections morbidity of 44 patients after caesarean section was determined to investigate the effect of short term prophylaxis with halospor and gentamycine. A control group of 104 patients remained without any antibiotic prophylaxis. The patients of the prophylaxis group showed a statistically significant reduction of postoperative infectious morbidity. The costs are equalized by reduction in therapeutic applications of antibiotics.     

Broad spectrum antibiotics as short term prophylaxis for elective abdominal hysterectomy: comparison of mezlocillin, cefazolin and placebo

A prospective randomized placebo controlled double-blind study was conducted in order to evaluate the effect of short term perioperative antibiotic prophylaxis on patients undergoing elective abdominal hysterectomy. Fifty-two patients received 3 doses of 0.5 g cefazolin, 54 patients received 3 doses of 1 g mezlocillin and 53 patients received placebo. Postoperative infectious morbidity and the rate of pelvic cellulitis were significantly lower in either antibiotic group in comparison to the placebo group, but neither drug proved to be superior in this respect. The fever index was significantly lower in the mezlocillin group in comparison to both cefazolin and placebo groups. It was thus concluded that antibiotic prophylaxis has a beneficial effect on patients undergoing abdominal hysterectomy and both drugs--cefazolin and mezlocillin--seem to be equally effective.     

Bulky stage IB cervical carcinoma managed by primary radical hysterectomy followed by tailored radiotherapy.

The management of bulky, stage IB cervical carcinoma remains controversial. The present study reports the outcome of 84 women treated by radical hysterectomy, in which the surgical specimen revealed a lesion measured to be 4 cm or greater in size following formalin fixation. Of the 84 women, 42 (50%) received postoperative radiotherapy based on additional surgical findings beyond tumor size suggesting a high risk for pelvic recurrence including lymph node metastasis, parametrial spread, and compromised margins. Despite the bulky nature of these lesions, major operative and early postoperative complication rates were low (6%). Delayed complications including fistulae and bowel obstructions occurred in only 2.4% of patients treated with surgery alone and in 14.2% of women treated with combined therapy. Corrected 5-year survival in this series was 70.4% (75.6% in the surgery only group and 65.0% in the surgery plus radiotherapy group). Recurrence and mortality rates were related to lesion size, with most recurrences and deaths occurring in women with lesions measuring 6 cm or greater. Comparison of these data utilizing primary radical hysterectomy followed by tailored radiotherapy with previously published data on similar groups of high-risk patients treated with either radiotherapy alone or with radiotherapy followed by simple hysterectomy suggests comparable survival and morbidity.
