Preoperative vaginal cleansing with chlorhexidine and cetrimide solution for reduction of postoperative infectious morbidity at a tertiary care center in North India: A prospective cohort study

OBJECTIVE

To determine the effect of preoperative vaginal cleansing with chlorhexidine and cetrimide solution on postoperative infectious morbidity.

METHODS

This prospective cohort study was conducted over a period of 18 months in the Department of Obstetrics and Gynecology, Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi, India. Women undergoing cesarean section were alternately allotted to study and control groups. Women with chorioamnionitis, antepartum hemorrhage, rupture of membranes for more than 24 h, and fever in the preoperative period were excluded. The study group received preoperative vaginal cleansing with antiseptic solution (7.5% chlorhexidine w/v and 15% cetrimide w/v); the control group did not receive vaginal cleansing. Both groups were followed for the presence of any infectious morbidity until they were discharged from the hospital.

RESULTS

Age, body mass index (calculated as weight in kilograms divided by the square of height in meters), gestational age, and the parity of the women in the study and control groups were comparable (n = 760). The rate of endometritis was lower in the study group, but the difference was not statistically significant (P = 0.054). Post-cesarean febrile morbidity and wound sepsis were significantly lower in the study group (P = 0.017 and P = 0.02, respectively). On subgroup analysis, women in the study group with rupture of the membranes before cesarean delivery had lower wound sepsis and a reduced duration of hospital stay. Women in the study group with emergency cesarean delivery showed a significant reduction in wound sepsis, febrile morbidity, and length of hospital stay.

CONCLUSION

Preoperative vaginal cleansing with chlorhexidine and cetrimide solution before a cesarean section reduces postoperative infectious morbidity.

Incidence and Risk Factors of Postoperative Febrile Morbidity among Patients Undergoing Myomectomy

Background and Objectives: To identify the incidence, causes, and independent predictors of postoperative febrile morbidity among patients undergoing myomectomy. Material and methods: Medical records of patients who had undergone myomectomy at Chiang Mai University Hospital between January 2017 and June 2022 were comprehensively reviewed. The clinical variables, including age, body mass index, previous surgery, leiomyoma size and number, the International Federation of Gynecology and Obstetrics (FIGO) fibroid type, preoperative and postoperative anemia, type of surgery, operative time, estimated blood loss, and intraoperative antiadhesive use, were analyzed as a predictive factor of postoperative febrile morbidity. Results: During the study period, 249 consecutive women were reviewed. The mean age was 35.6 years. The majority of women had FIGO fibroid type 3-5 (58.2%) and type 6-8 (34.2%). Febrile morbidity was noted in 88 women (35.34%). Of them, 17.39% had a urinary tract infection and 4.34% had a surgical site infection, whereas the causes in the majority of cases (78.26%) could not be identified. The significant independent risk factors for febrile morbidity were abdominal myomectomy (adjusted odds ratio: aOR, 6.34; 95% CI, 2.07-19.48), overweight women (aOR, 2.25; 95% CI, 1.18-4.28), operation time of more than 180 min (aOR, 3.37; 95% CI, 1.64-6.92), and postoperative anemia (aOR, 2.71; 95% CI, 1.30-5.63). Conclusions: Approximately one-third of women undergoing myomectomy experienced febrile morbidity. The cause could not be identified in most cases. The independent risk factors included abdominal myomectomy, overweight, prolonged operation time, and postoperative anemia. Of them, abdominal myomectomy was the most significant risk factor.

Single Dose Versus 72-Hour Course of Ceftriazone for Antibiotic Prophylaxis in Preventing Post-Caesarean Wound Infection: A Randomized Control Trial

Background

Single dose antibiotic prophylaxis has been established as the standard for prevention of post-caesarean wound infection in most developed centers across the world. However, this is not the case in most developing countries including Nigeria where various multiple dose regimens are still being used due to paucity of locally generated evidence, and anecdotal suggestions of a higher risk of infectious morbidity in our environment.

Objectives

This study was aimed to determine whether there was a significant difference in the incidence of post-caesarean section wound infection between a single dose and a 72-hour course of intravenous ceftriazone for antibiotic prophylaxis in selected patients undergoing both elective and emergency caesarean section.

Materials and Methods

A randomized controlled trial was carried out among 170 consenting parturients scheduled for elective or emergency caesarean section who met a set out selection criteria, between January and June 2016. They were divided randomly into two equal groups, A and B, of 85 each using the Windows WINPEPI software version 11.65 (Copyright J.H. Abrahamson, 22 Aug 2016) for randomization. Group A patients received a single dose of 1 g, whereas Group B patients were given a 72-hour course (1 g daily) of intravenous ceftriazone. The primary outcome measure was the incidence of clinical wound infection. The secondary outcome measures were the incidences of clinical endometritis and febrile morbidity. Data were collected using a structured proforma and analyzed using Statistical Package for Social Sciences version 21.

Results

The overall incidence of wound infection was 11.2%; Group A had 11.8%, and Group B had 10.6%. Endometritis was 20.6%; Group A had 20% and Group B had 21.2%. Febrile morbidity was 4.1%; Group A had 3.5% and Group B had 4.7%. There was no statistically significant difference in the incidence of wound infection (relative risk [RR] = 1.113; 95% confidence interval [CI] = 0.433, 2.927; P = 0.808), endometritis (RR = 0.943; 95% CI = 0.442, 1.953; P = 0.850), and febrile morbidity (RR = 0.745, 95% CI = 0.161, 3.415; P = 0.700) between the two groups. Group A showed similar risk of developing wound infection compared to Group B (P > 0.05).

Conclusion

There was no significant difference in post-caesarean wound infection and other infectious morbidity between patients that received a single dose, and those that received a 72-hour course of ceftriazone for antibiotic prophylaxis. This suggests that single dose antibiotic prophylaxis with ceftriazone is similar to multiple dose regimens in efficacy with likely cost-effective advantage.

Efficiency of using a vaginal drain after hysterectomy: A systematic review

Objective Hysterectomy is the second most frequently performed surgical procedure for women of reproductive age topped only by caesarean section. Hysterectomies may be associated with a significant risk of ultrasonographically detected vault haematomas in up to 59% with consequent postoperative morbidity. The aim of this systematic review was to compare women who had a vaginal drain placed intraoperatively after a hysterectomy and the impact on peri and postoperative outcomes related to vault haematomas. Study Design Electronic searches of AMED, BNI, CINAHL, EMBASE, HBE, HMIC, Medline, PsycINFO and PubMed, Cochrane register of controlled trials (CCTR), Cochrane database of systematic reviews (CDSR) CINAHL and Google scholar were performed. A systematic review and meta-analysis of studies comparing women with and without a vaginal drain after a hysterectomy and the impact on different outcomes was carried out. Results Ten studies involving 1778 women, 811 with a vaginal drain and 967 without a drain, were included in the meta-analysis. This suggests that the use of a vaginal drain after hysterectomy may significantly reduce the incidence of vault haematoma (OR 0.22, 95% CI 0.08 - 0.57) and febrile morbidity (OR 0.54, 95% CI 0.40 to 0.73), non- significantly reduce the rate of usage of antibiotics (OR 0.80, 95% CI 0.46-1.42) and makes no difference to the length of hospital stay (MD 0.12, 95% CI -0.14 to 0.38). Conclusion The use of a vaginal drain after hysterectomy could reduce the incidence of vault haematoma and febrile morbidity.

Vaginal vault drainage after complicated single-port access laparoscopic-assisted vaginal hysterectomy

Study objective:

To evaluate the feasibility and safety of vaginal vault drainage after complicated singleport access laparoscopic-assisted vaginal hysterectomy (SPA-LAVH).

Design:

Retrospective cohort study.

Setting:

Ulsan University Hospital (tertiary teaching hospital), South Korea.

Patients:

A total of 359 women underwent SPA-LAVH for the following conditions: benign uterine tumor, preinvasive uterine lesion, and microinvasive cervical cancer.

Interventions:

The participants included 124 women with vault drains and 235 women without drains.

Measurements:

Surgical outcomes, perioperative complications and morbidity, postoperative febrile morbidity.

Results:

There were no differences in background features between drain and no-drain groups. In surgical outcomes, mean uterine weight (364.2 ± 184.9 g vs. 263.7 ± 138.6 g; p < 0.001), operation time (87.4 ± 21.5 min vs. 73.0 ± 17.6 min; p < 0.001), blood loss (225.3 ± 122.2 mL vs. 150.4 ± 95.2 mL; p < 0.001), and hemoglobin decline (1.97 ± 0.96 g/dL vs. 1.42 ± 0.89 g/dL; p < 0.001) were significantly larger for the drain group compared with the no-drain group. However, with regard to postoperative morbidity and complications, there were no group differences in the transfusion rates (6.5% vs. 3.8%; p = 0.300), intraoperative complications (2.4% vs. 1.3%; p = 0.420), perioperative complications (2.4% vs. 0.9%; p = 0.345), and febrile morbidity ≥ 37.5°C (8.9% vs. 11.5%; p = 0.477), although the drain group was more prone to the development of pelvic fluid collection and febrile morbidity than the no-drain group.

Conclusion:

Vaginal vault drainage could be a safe alternative that allows for the management of postoperative morbidity and retains the advantages of minimally invasive surgery after complicated SPA-LAVH.

Postoperative Infection in the Setting of Massive Intraoperative Blood Loss

OBJECTIVE

To determine the local rates of massive intraoperative blood loss and subsequent infectious morbidity for patients undergoing gynaecologic laparotomy.

METHODS

We performed a retrospective chart review of all patients undergoing gynaecologic laparotomy between January 1, 2013 and December 31, 2013 to identify cases of massive intraoperative blood loss (defined as ≥1 L estimated intraoperative blood loss, a postoperative reduction in hemoglobin concentration of ≥40 g/L, or a perioperative blood transfusion). For cases meeting these criteria, we abstracted further data to assess the rate of postoperative infectious morbidity (defined as a positive wound swab culture, positive urine culture, or satisfying the 1991 criteria for systemic inflammatory response syndrome).

RESULTS

The rate of massive intraoperative blood loss was 13.5% (n = 69). The average age in this cohort was 50.4 years (range 18-84 years) and the average BMI was 27.9 kg/m². Perioperative transfusion was required in 31.9% (n = 22). Notably, 26.1% of patients (n = 18) met one of our primary endpoints for postoperative infectious morbidity. A further 10.1% (n = 7) had morbidities including hyponatremia, wound dehiscence, intra-abdominal abscess, positive blood cultures, acute respiratory distress syndrome, myocardial infarction, intensive care unit admission, or death.

CONCLUSION

Our rate of massive intraoperative blood loss during gynaecologic laparotomy was found to be 13.5%, and our rate of postoperative infectious morbidity subsequent to massive intraoperative blood loss was 26.1%.

A prospective randomized controlled comparison of immediate versus late removal of urinary catheter after abdominal hysterectomy

Objective:

Indwelling transurethral catheter is frequently used after gynecological surgeries in order to prevent urinary retention. There is controversy about the ideal time to remove the catheter after surgery. This randomized controlled study was undertaken to determine whether the immediate removal of urinary catheter after abdominal hysterectomy affects the rate of symptomatic urinary tract infection (UTI), recatheterization, subjective pain perception and febrile morbidity.

Study Design:

This prospective randomized controlled trial included 70 women undergoing abdominal hysterectomy with or without salpingoophrectomy for benign diseases. Patients were divided into two equal groups on the basis of timing of removal of urinary catheter (Group I — Immediate removal after surgery, Group II — Removal after 24 h and evaluated for benefits versus risks of immediate catheter removal. The results were compared by the Chi-square test.

Results:

Recatheterization was required in three patients of immediate removal group and none in late removal group (P = 0.07). Higher incidence of positive urine cultures (25.9%) and febrile morbidity (10%) was found in Group II when compared to immediate removal group (8%). Pain perception was not statistically different in both groups (P = 0.567).

Conclusions:

The early removal of an indwelling catheter after surgery was not associated with an increased rate of febrile events, UTI. Pain perception was also lower in early removal group. Although need of recatheterization was higher in early removal group, but not statistically significant.

Incidence of and risk factors for febrile morbidity after laparoscopic-assisted vaginal hysterectomy

Background

The purpose of this study was to assess the incidence of and risk factors for postoperative febrile morbidity after laparoscopic-assisted vaginal hysterectomy (LAVH).

Methods

This retrospective study was carried out using the medical records of women with benign gynecologic conditions who underwent LAVH between June 2007 and May 2012 at Srinagarind Hospital in Thailand. Data were collected to assess baseline patient characteristics, occurrence of body temperature ≥38°C on two occasions at least 6 hours apart in the 24 hours following the surgical procedure, and possible risk factors related to postoperative febrile morbidity.

Results

In total, 199 women underwent LAVH during the study period. They had a mean age of 46±6 years, a mean body mass index of 24.0±3.2 kg/m², a mean surgical duration of 134±52 minutes, median estimated blood loss of 200 mL, a mean total hospital stay of 5±2 days, and a mean postoperative hospital stay of 3±2 days. Postoperative febrile morbidity was documented in 31 cases (15.6%). The cause of postoperative fever was unknown in most cases, with only two cases having an identifiable cause. The risk of postoperative febrile morbidity was highest in women treated with more than two antibacterial agents and with a regimen of more than 3 days.

Conclusion

This study shows a moderately high rate of febrile morbidity after LAVH, for which the main risk factors were use of multiple drugs and doses for antibiotic prophylaxis.
