The Role of Topical Antibiotic Prophylaxis in Oculofacial Plastic Surgery: A Randomized Controlled Study.

ABSTRACT:

Purpose

The usefulness of topical antibiotic prophylaxis for routine oculofacial plastic surgery is not well established. Given concerns such as contact dermatitis, antibiotic resistance, and healthcare costs in conjunction with a low baseline rate of surgical site infections, the investigators sought to determine the frequency of infection with and without the use of topical antibiotic prophylaxis.

Design

Randomized, controlled, unmasked clinical trial.

Participants

Adult patients undergoing routine periocular surgery without prior history of periocular surgical site infection, need for perioperative oral or parenteral antibiotics, or allergy to all study medications.

Methods

Participants were randomized before surgery to receive either antibiotic or placebo (mineral oil and petrolatum-based) ointment after surgery. Outcomes were measured at the first postoperative visit. The 2-tailed Fisher exact test was used to compare outcomes between groups.

Main outcome measures

The primary outcome was the incidence of surgical site infections. The secondary outcomes included stratification of infections by patient risk characteristics, incidence of allergic contact dermatitis, and incidence of wound complications.

Results

Four hundred one participants were enrolled and randomized, and 13 participants did not proceed with surgery or were lost to follow-up. High-risk features for infection were identified in 24% of the placebo group and 21% of the antibiotic group. Surgical site infections were more common in the placebo group (2.7% vs. 0.0%; P = 0.025). The rate of contact dermatitis was similar (0.5% vs. 0.5%; P = 1.00), as was the rate of wound dehiscence (2.7% vs. 3.5%; P = 0.77). Among the placebo group, the incidence of infections in the low- and high-risk participants was 2.9% and 2.2%, respectively. Infections were treated with oral or topical antibiotics and resolved without complication, except in 1 patient who required 2 subsequent surgeries to address the sequelae.

Conclusions

After routine oculofacial plastic surgery, patients treated with a topical antibiotic ointment showed a lower risk of surgical site infection compared with patients treated with a nonantibiotic ointment.

Project description:BackgroundRecent meta-analyses concluded that antibiotic prophylaxis is not warranted in low-risk laparoscopic cholecystectomy. However, most trials in the meta-analyses had a relatively small sample size and were statistically underpowered. In addition, many of the trials mentioned potential cost savings owing to the elimination of prophylactic antibiotics. However, no trial has statistically estimated the cost effectiveness. To evaluate the results of meta-analyses, we conducted a randomized controlled trial on the role of prophylactic antibiotics in low-risk laparoscopic cholecystectomy with an adequate sample size.MethodsFrom March 2007 to May 2013, at the Department of Surgery, Kansai Medical University, patients who were scheduled for elective laparoscopic cholecystectomy were randomly assigned to one of two arms: those who were and were not administered prophylactic antibiotics. The primary endpoint was the occurrence of postoperative infections and secondary endpoints were postoperative hospital stay and medical costs.FindingsDuring the study period, 518 patients were assigned to the Antibiotics group and 519 to the No antibiotics group. Occurrences of surgical site infections, distant infections and overall infections were significantly lower in the Antibiotics group than in the No antibiotics group (0.8 vs. 3.7%, p?=?0.001, OR: 0.205 (95%CI: 0.069 to 0.606); 0.4 vs. 3.1%, p?=?0.0004, OR: 0.122 (95%CI: 0.028 to 0.533); 1.2 vs. 6.7%; p<0.0001, OR: 0.162 (95%CI: 0.068 to 0.389), respectively). The postoperative hospital stay was significantly shorter in the Antibiotics group (mean, SD: 3.69±1.56 vs. 4.07±3.00; p?=?0.01) and the postoperative medical costs were significantly lower in the Antibiotics group (mean, SD: $766±341 vs. 832±670; p?=?0.047). Multivariable analysis showed that independent risk factors for postoperative infectious complications were no prophylactic antibiotics (p<0.0001) and age 65 or older (p?=?0.006).ConclusionsPerioperative administration of prophylactic antibiotics should be recommended in laparoscopic cholecystectomy to prevent postoperative infectious complications and to reduce medical costs.Trial registrationUMIN Clinical Trials Registry UMIN000003749.

Project description:BACKGROUND:Colorectal surgery is frequently complicated by surgical site infections (SSIs). The most important consequences of SSIs are prolonged hospitalization, an increased risk of surgical reintervention and an increase in mortality. Perioperative intravenously administered antibiotic prophylaxis is the standard of care to reduce the risk of SSIs. In the last few decades, preoperative orally administered antibiotics have been suggested as additional prophylaxis to further reduce the risk of infection, but are currently not part of routine practice in most hospitals. The objective of this study is to evaluate the efficacy of a preoperative orally administered antibiotic prophylaxis (Pre-OP) in addition to intravenously administered perioperative antibiotic prophylaxis to reduce the incidence of deep SSIs and/or mortality after elective colorectal surgery. METHODS/DESIGN:The PreCaution trial is designed as a multicenter, double-blind, randomized, placebo-controlled clinical trial that will be carried out in The Netherlands. Adult patients who are scheduled for elective colorectal surgery are eligible to participate. In total, 966 patients will be randomized to receive the study medication. This will either be Pre-OP, a solution that consists of tobramycin and colistin sulphate, or a placebo solution. The study medication will be administered four times daily during the 3 days prior to surgery. Perioperative intravenously administered antibiotic prophylaxis will be administered to all patients in accordance with national infection control guidelines. The primary endpoint of the study is the cumulative incidence of deep SSIs and/or mortality within 30 days after surgery. Secondary endpoints include both infectious and non-infectious complications of colorectal surgery, and will be evaluated 30 days and/or 6 months after surgery. DISCUSSION:To date, conclusive evidence on the added value of preoperative orally administered antibiotic prophylaxis in colorectal surgery is lacking. The PreCaution trial should determine the effects of orally administered antibiotics in preventing infectious complications in elective colorectal surgery.

Project description:BackgroundThe indication for antibiotic prophylaxis in burn patients remains highly controversial, with no consensus having been reached. The objective of antibiotic prophylaxis is to reduce the risk of postoperative local and systemic infections. Burn surgery is associated with a high incidence of bacteremia, postoperative infections, and sepsis. However, antibiotic prophylaxis exposes patients to the risk of selecting drug-resistant pathogens as well as to the adverse effects of antibiotics (i.e., Clostridium difficile colitis). The lack of data precludes any strong international recommendations regarding perioperative prophylaxis using systemic antibiotics in this setting. The goal of this project is therefore to determine whether perioperative systemic antibiotic prophylaxis can reduce the incidence of postoperative infections in burn patients.MethodsThe A2B trial is a multicenter (10 centers), prospective, randomized, double-blinded, placebo-controlled study. The trial will involve the recruitment of 506 adult burn patients with a total body surface area (TBSA) burn of between 5 and 40% and requiring at least one excision-graft surgery for deep burn injury. Participants will be randomized to receive antibiotic prophylaxis (antibiotic prophylaxis group) or a placebo (control group) 30 min before the incision of the first two surgeries. The primary outcome will be the occurrence of postoperative infections defined as postoperative sepsis and/or surgical site infection and/or graft lysis requiring a new graft within 7 days after surgery. Secondary outcomes will include mortality at day 90 postrandomization, skin graft lysis requiring a new graft procedure, postoperative bacteremia (within 48 h of surgery), postoperative sepsis, postoperative surgical site infection, number of hospitalizations until complete healing (> 95% TBSA), number of hospitalization days living without antibiotic therapy at day 28 and day 90, and multiresistant bacterial colonization or infection at day 28 and day 90.DiscussionThe trial aims to provide evidence on the efficacy and safety of antibiotic prophylaxis for excision-graft surgery in burn patients.Trial registrationClinicalTrials.gov NCT04292054 .
