Cystoscopy with antibiotic irrigation during pelvic reconstruction and minimally invasive gynecologic surgery: A double-blind randomized controlled trial.

After pelvic reconstructive surgery, the risk of postoperative urinary tract infection (UTI) is significant; intraoperative cystoscopy may contribute to this risk. Intravesical antibiotics are used in the ambulatory setting and may be applied to the surgical arena. Our objective was to evaluate the efficacy of antibiotic irrigation during intraoperative cystoscopy to prevent postoperative UTI. This double-blind randomized controlled trial enrolled 216 women undergoing cystoscopy with elective surgery for pelvic organ prolapse, stress urinary incontinence, or laparoscopic gynecologic surgery at an academic medical center 2016-2019. Participants were randomized to cystoscopic irrigation fluid type: normal saline (control) or 200,000 U polymyxin B + 40 mg neomycin solution in normal saline (antibiotic). Patients and providers who treated UTIs were blinded. The primary outcome was treatment of UTI within 6 weeks postoperatively, defined as positive culture or treatment for a symptomatic UTI. χ2 and multivariable logistic regression analyses were performed. We enrolled 216 women: 111 control (51.4%) and 105 antibiotic (48.6%). Mean age was 51.6 years. Groups were well matched in medical comorbidities and surgery type. Primary vaginal surgery was most common (n = 127, 58.8%). Overall, 10.7% of patients developed a postoperative UTI with no difference in incidence between groups: 9.9% of control (n = 11, 95% confidence interval [CI]: 4.0%-16.0%) versus 11.4% of antibiotic subjects (n = 12, 95% CI: 5.0%-18.0%), on χ2 (p = .718) and logistic regression analysis (adjusted odds ratio, 1.3; CI: 0.53-3.16; p = .569). When cystoscopy is performed during elective pelvic surgery, use of antibiotic irrigation does not impact the rate of postoperative UTI.

Breast Pocket Irrigation with Antibiotic Solution at Implant Insertion: A Systematic Review and Meta-Analysis.

Antibiotic irrigation is routinely used during implant insertion in augmentation mammoplasty procedures. However, the evidence for whether this reduces the incidence of infection or capsular contracture is unclear. Five databases were used to search for all randomized control trials, retrospective cohort and prospective cohort studies containing original data related to the primary outcomes being investigated in this study. The primary outcomes were the effects of antibiotic breast pocket irrigation on clinical infection and capsular contracture. The literature search was designed to combine three concepts: implant or tissue expander-based breast surgery, antibiotic irrigation and clinical infection or capsular contracture. Studies found were screened using specific eligibility criteria. Risk ratios (RR) and 95% confidence interval (CI) were calculated using pooled acquired data from all included studies. The search identified 1256 citations. Three independent screeners identified seven studies that met the inclusion criteria with a pooled population of 4725. This included one prospective and six retrospective studies. A meta-analysis of pooled study data showed significant reductions in clinical infection (RR 0.52, 95% CI 0.33-0.81) and capsular contracture (RR 0.36, 95% CI 0.16-0.83) as a result of antibiotic irrigation. The meta-analyses support the use of antibiotic irrigation of the breast pocket. However, the results of this study are limited by the large proportion of retrospective studies, the small number of studies included, the lack of randomized controlled trials and the heterogeneity of the antibiotic and control regimes used.

Antibiotic Irrigation of Pocket for Implant-Based Breast Augmentation to Prevent Capsular Contracture: A Systematic Review.

In vitro and in vivo studies have described a number of different antibiotic solutions for irrigation of the pocket in implant-based breast augmentation in an attempt to prevent the formation of capsular contracture (CC). Our objective was to evaluate the evidence that antibiotic irrigation reduced the rate of CC. A systematic search of MEDLINE, EMBASE, and CENTRAL was conducted from inception to January 2016. We included studies which examined the use of intraoperative antibiotic irrigation in women undergoing primary breast augmentation. Our primary outcome was the rate of CC. Included studies were assessed for methodological quality using validated tools. Seven studies were included in the final analysis: 1 randomized controlled trial (RCT) and 6 non-randomized studies. The mean follow-up ranged from 14 to 72 months. The rate of CC was less than 2% in 8 studies, between 3% and 6% in 4 studies, and 13.9% in 1 study. Included studies demonstrated significant clinical and methodological heterogeneity. The solitary low-quality RCT concluded that antibiotic irrigation was superior to saline irrigation. Three non-randomized studies demonstrated no significant difference in the rate of CC with the use of antibiotics. One non-randomized controlled study showed that the use of mixture of antibiotic and povidone-iodine significantly lowered the rate of CC. The available evidence on the use of antibiotic irrigation to prevent CC is weak and it is based on studies with high risk of bias. Methodologically robust studies are necessary to answer the question whether antibiotic breast pocket irrigation prevents CC.

Intra-Operative Surgical Irrigation of the Surgical Incision: What Does the Future Hold-Saline, Antibiotic Agents, or Antiseptic Agents?

Intra-operative surgical site irrigation (lavage) is common practice in surgical procedures in general, with all disciplines advocating some form of irrigation before incision closure. This practice, however, has been neither standardized nor is there compelling evidence that it effectively reduces the risk of surgical site infection (SSI). This narrative review addresses the laboratory and clinical evidence that is available to support the practice of irrigation of the abdominal cavity and superficial/deep incisional tissues, using specific irrigation solutions at the end of an operative procedure to reduce the microbial burden at wound closure. Review of PubMed and OVID for pertinent, scientific, and clinical publications in the English language was performed. Incision irrigation was found to afford a three-fold benefit: First, to hydrate the bed; second, to assist in allowing better examination of the area immediately before closure; and finally, by removing superficial and deep incisional contamination and lowering the bioburden, expedite the healing process. The clinical practice of intra-operative peritoneal lavage is highly variable and is dependent solely on surgeon preference. By contrast, intra-operative irrigation after device-related procedures has become a standard of care for the prophylaxis of acute peri-prosthetic infection. The clinical evidence that supports the use of antibiotic irrigation is limited and based on retrospective analysis and few acceptable randomized controlled trials. The results of laboratory and animal studies using aqueous 0.05% chlorhexidine gluconate are favorable, suggesting that further studies are justified to determine its clinical efficacy. The adoption of appropriate and standardized intra-operative irrigation practices into peri-operative care bundles, which include other evidence-based strategies (weight-based antimicrobial prophylaxis, antimicrobial sutures, maintenance of normothermia, and glycemic control), offers an inexpensive and effective method to reduce the risk of post-operative SSI and deserves further evaluation.

Prophylactic peri-operative local antibiotic irrigation

An extensive review of the spinal and arthroplasty literature was undertaken to evaluate the effectiveness of local antibiotic irrigation during surgery. The efficacy of antibiotic irrigation for the prevention of acute post-operative infection after total joint arthroplasty was evaluated retrospectively in 2293 arthroplasties (1990 patients) between January 2004 and December 2013. The mean follow-up was 73 months (20 to 139). One surgeon performed all the procedures with minimal post-operative infection. The intra-operative protocol included an irrigation solution of normal saline with vancomycin 1000 mg/l and polymyxin 250,000 units/l at the rate of 2 l per hour. No patient required re-admission for primary infection or further antibiotic treatment. Two morbidly obese patients (two total hip arthroplasties) developed subcutaneous fat necrosis requiring debridement and one was revised because the deep capsular sutures were contaminated by the draining subcutaneous haematoma. One patient who had undergone total knee arthroplasty had unrecognised damage to the lateral superior geniculate artery and developed a haematoma that became infected secondarily four months after the surgery and underwent revision. The use of antibiotic irrigation during arthroplasty surgery has been highly effective for the prevention of infection in the author's practice. However, it should be understood that any routine prophylactic use of antibiotics may result in resistant organisms, and the wise stewardship of the use of antibiotics is an important part of surgical practice.

Revisiting Triple Antibiotic Irrigation of Breast Implant Pockets: A Placebo-controlled Single Practice Cohort Study.

Background:Capsular contracture is the most common complication following primary augmentation mammoplasty. It remains poorly understood but is attributed to subclinical infection, immunologic response to breast implants, and chronic inflammatory changes caused by the presence of the implants. The infectious theory of contracture has lead to the practice of irrigating implant pockets with a triple antibiotic solution. The purpose of this study was to determine if antibiotic irrigation reduced the incidence and severity of capsular contracture compared with saline irrigation.Methods:A cohort study enrolling all patients having undergone primary augmentation mammoplasty performed by surgeon A and surgeon B between 2011 and 2012 for all women satisfying inclusion and exclusion criteria was conducted. The only difference in surgical technique was the use of antibiotic irrigation by surgeon B. A chi-square test and analysis of variance with predetermined 95% confidence intervals were performed.Results:Fifty-five patients were operated on. Twenty-eight of surgeon A’s patients were included, ranging in age from 22 to 50 with a mean follow-up time of 1.8 years. Twenty-seven of surgeon B’s patients were included, ranging in age from 22 to 56 with a mean follow-up time of 1.6 years. Rate of capsular contracture was 3.6% (surgeon A) and 3.7% (surgeon B). Chi-square statistic was found to be 0.0014 (P = 0.97) and analysis of variance F value was 1 (P = 0.39).Conclusions:Triple antibiotic breast irrigation is not associated with a significant reduction in the incidence or severity of capsular contracture compared with sterile saline when high-quality surgical technique is used.

Risk Factors Associated with Deep Surgical Site Infections After Primary Total Knee Arthroplasty

Deep surgical site infection following total knee arthroplasty is a devastating complication. Patient and surgical risk factors for this complication have not been thoroughly examined. The purpose of this study was to evaluate risk factors associated with deep surgical site infection following total knee arthroplasty in a large U.S. integrated health-care system. A retrospective review of a prospectively followed cohort of primary total knee arthroplasties recorded in a total joint replacement registry from 2001 to 2009 was conducted. Records were screened for deep surgical site infection with use of a validated algorithm, and the results were adjudicated by chart review. Patient factors, surgical factors, and surgeon and hospital characteristics were identified with use of the total joint replacement registry. Cox regression models were used to assess risk factors associated with deep surgical site infection. A total of 56,216 total knee arthroplasties were identified; 63.0% were done in women, the average age of the patients was 67.4 years (standard deviation [SD] = 9.6), and the average body mass index (BMI) was 32 kg/m2 (SD = 6). The incidence of deep surgical site infection was 0.72% (404/56,216). In a fully adjusted model, patient factors associated with deep surgical site infection included a BMI of ≥35 (hazard ratio [HR] = 1.47), diabetes mellitus (HR = 1.28), male sex (HR = 1.89), an American Society of Anesthesiologists (ASA) score of ≥3 (HR = 1.65), a diagnosis of osteonecrosis (HR = 3.65), and a diagnosis of posttraumatic arthritis (HR = 3.23). Hispanic race was protective (HR = 0.69). Protective surgical factors included use of antibiotic irrigation (HR = 0.67), a bilateral procedure (HR = 0.51), and a lower annual hospital volume (HR = 0.33). Surgical risk factors included quadriceps-release exposure (HR = 4.76) and the use of antibiotic-laden cement (HR = 1.53). In a subanalysis, operative time was a risk factor, with a 9% increased risk per fifteen-minute increment. Use of a comprehensive infection surveillance system, combined with a total joint replacement registry, identified patient and surgical factors associated with infection following total knee arthroplasty in a large sample. High-risk patients should be counseled, and modifiable clinical conditions should be optimized. Use of antibiotic irrigation should be encouraged, but antibiotic-laden cement may not be useful.

What Is the Role of Antibiotic-Containing Cement in Total Knee Arthroplasty?

Despite a prevalence of <1% in most series, periprosthetic joint infection is a devastating complication that is of major concern to patients, surgeons, and payers because of its attendant disability, difficult treatment, and cost. Risk factors leading to periprosthetic joint infection and methods of prevention are difficult to investigate because these infections are uncommon and large patient populations are necessary for sufficient statistical power to differentiate between treatment methods or to identify causative factors. The May 1 issue of JBJS includes two important contributions toward understanding infection after total knee arthroplasty; however, both papers also demonstrate the problems attendant to investigating this clinical problem. Risk Factors Associated with Deep Surgical Site Infections After Primary Total Knee Arthroplasty by Namba et al. is an observational study of prospectively collected data on 56,216 patients treated with primary total knee arthroplasty derived from the total joint replacement registry of the Kaiser Permanente health system. As has been reported in other studies, the authors showed that deep surgical site infection was associated with obesity, male sex, osteonecrosis, posttraumatic arthritis, and duration of surgery. The authors found that Hispanic race was protective against deep infection as was the use of antibiotic irrigation. Paradoxically, they also found that antibiotic-containing bone …

Results of infected total knee arthroplasty treated with arthroscopic debridement and continuous antibiotic irrigation system

Background:Arthroscopic debridement with continuous irrigation system was used with success in treating infective arthritis. We evaluated the effectiveness of arthroscopic debridement coupled with antibiotic continuous irrigation system in acute presentation of late infected total knee arthroplasty.Materials and Methods:We performed a retrospective review of medical record of patients with acute presentation of late infected total knee arthroplasty who were treated by arthroscopic debridement coupled with continuous postoperative antibiotic irrigation system.Results:Seventeen patients were included in our study. 15 (88%) patients preserved their total knee prosthesis at mean of followup of 27.5 months (range, 14-28 months). Two (12%) patients failed arthroscopic protocol and finally needed two stages revision. Our study showed an 88% prosthesis retention rate in patients with acute presentation of late prosthetic knee infection. No complication was associated with use of antibiotic irrigation system.Conclusion:Arthroscopic debridement combined with continuous antibiotic irrigation and suction is an effective treatment for patients with acute presentation of late infected total knee arthroplasty.

Ventriculostomy-associated infections: Incidence and risk factors

The objective of this study was to assess the incidence of ventriculostomy-associated infections (VAI) and to examine the related risk factors. Data on all consecutive patients with ventriculostomy catheters admitted to the intensive care unit (ICU) in a tertiary care center over a 3-year period were identified from the ICU database and from medical records. VAI was documented using a preset definition. The following patient data were documented: demographics, severity of illness measures, indication for the catheter, presence of cerebrospinal fluid (CSF) leak, and length of stay and mortality. The following catheter data were collected: venue of catheter placement (operating room or nonoperating room areas), use of antibiotic irrigation and prophylactic systemic antibiotics, and number of catheter days. The frequency of CSF sampling was documented. In 84 patients, 99 catheters were placed, of which 19% developed VAI. There was a total of 586 catheter days (infection rate, 32 per 1000 catheter days). The risk of VAI increased steadily until catheter day 7 then reached a plateau. Among patients' factors, repeat catheter insertion was associated with a significant increase in VAI. There were no significant associations with age, severity of illness, indication for the catheter, craniatomy, or presence of CSF leak. Among catheter factors, the number of catheter days and repeat catheter insertion emerged as significant independent predictors on multivariate analysis. Placement outside the operating room was associated with a trend toward higher VAI. The use of prophylactic antibiotic or antibiotic irrigation did not significantly alter VAI rates. Routine surveillance cultures of CSF were no more likely to detect infection than cultures obtained when clinically indicated. Gram-negative bacilli were responsible for 50% of the infections, followed by gram-positive cocci (29%) and others (21%). The risk of VAI increases with increasing duration of catheterization and with repeated insertions. The use of local antibiotic irrigation or systemic antibiotics does not appear to reduce the risk of VAI. Routine surveillance cultures of CSF were no more likely to detect infection than cultures obtained when clinically indicated. These findings need to be considered in infection control policies addressing this important issue.

Risk factors for complications in pediatric tissue expansion.

Tissue expansion in children has been associated with complication rates of 20 to 40 percent. A critical analysis of 6 years' (1988-1993) experience with 180 expanders placed in 82 consecutive children was performed to identify those factors which predispose to complications. Major and minor complications each occurred in 9 percent of patients. The factors associated with a statistically significant increase in complications were burns and soft-tissue loss, patient age under 7 years, use of internal expander ports, and a history of two or more prior expansions. In addition, complications were significantly more likely to occur within the first 90 days than during any subsequent expansion. Factors that did not influence complication rate included patient gender, wound drainage upon expander insertion or removal, intraoperative use of antibiotic irrigation, number of expanders placed, use of customized expanders, and operating surgeon.
