Do We Need Preoperative Antibiotics in Common General Pediatric Surgery Procedures?

Background There are limited studies on the necessity of preoperative antibiotics in surgeries for undescended testis (UDT), inguinal hernia (IH), and umbilical hernia (UH) in children. Here, we investigated the relationship between preoperative antibiotic use and surgical site infection (SSI) incidence in surgeries for UDT, IH, and UH in children. Methods Patients who underwent surgery for IH were subdivided based on the surgical form into those who underwent (i) open IH (OIH) repair and (ii) laparoscopic percutaneous extraperitoneal closure (LPEC). Medical records of patients who underwent surgeries for UDT and IH or UH were retrospectively examined. The SSI incidence was compared between patients receiving and not receiving preoperative antibiotics. In patients who underwent surgery for UH or LPEC, the relative risk of SSI postoperatively in the inguinal region (including surgery for UDT and OIH repair) was examined. Results In total, 926 patients with 1389 wounds were included in this study. SSI rates in patients who underwent surgeries for UDT and UH, OIH repair, and LPEC were 0.2% and 2.7%, 0.3%, and 0.4%, respectively. These rates were not significantly different between patients receiving and not receiving preoperative antibiotics. In patients who underwent surgery for UH, the relative risk of SSI was statistically significant at 9.8 compared with that in patients who underwent surgeries in the inguinal region (95% CI = 1.3-74; p = 0.013). Conclusions Preoperative antibiotics are unnecessary in surgeries for UDT and OIH repair. Patients undergoing surgery for UH should be given extensive care as they are at a high risk of SSI.

Effect of Comorbidities on the Incidence of Surgical Site Infection in Patients Undergoing Emergency Surgery: A Systematic Review and Meta-Analysis.

Background: Surgical site infection (SSI) is a significant concern in patients undergoing emergency surgery, particularly in those with underlying comorbidities. This meta-analysis aimed to evaluate the effect of comorbidities, including diabetes mellitus, hypertension, obesity, pulmonary disease, cardiac disease, liver disease, and renal disease, on the incidence of SSI in patients undergoing emergency surgery. Methods: We performed a systematic literature search across electronic databases including PubMed, ScienceDirect, Cochrane Library, ProQuest, and Google Scholar to identify studies examining the effect of comorbidities on the incidence of SSI in patients undergoing emergency surgery. To determine the effect size, pooled odds ratios (ORs) were calculated. Statistical analysis was performed using Review Manager 5.3 software. Results: Thirteen studies involving 8,952 patients undergoing emergency surgery were included in this meta-analysis. The pooled analysis showed that the following comorbidities significantly increased the risk of SSI following emergency surgery: diabetes mellitus (OR = 2.22; 95% confidence interval (CI) = 1.52 - 3.25; P < 0.0001), obesity (OR = 1.43; 95% CI = 1.19 - 1.72; P = 0.0001), and liver disease (OR = 1.66; 95% CI = 1.37 - 2.00; P < 0.00001). However, hypertension, pulmonary disease, cardiac disease, and renal disease showed no significant association with SSI. Conclusions: In patients undergoing emergency surgery, the presence of comorbidities including diabetes mellitus, obesity, and liver disease increases the incidence of developing SSI.

Association of negative pressure wound therapy and surgical site infections in patients undergoing cytoreductive surgery: An entropy balanced analysis.

BACKGROUND AND OBJECTIVES: Surgical site infections (SSIs) after cytoreductive surgery (CRS) ± hyperthermic intraperitoneal chemotherapy (HIPEC) are a major cause of potentially avoidable morbidity. We explored the association of negative pressure wound therapy (NPWT) with SSI in patients undergoing CRS/HIPEC. METHODS: Retrospective analysis of consecutive patients undergoing CRS/HIPEC for non-gynecologic cancers. Exposure was the receipt of NPWT versus traditional skin closure. Primary outcome was SSI within 90 days of surgery. We performed multivariable logistic regression (before and after entropy balancing) to evaluate the association of exposure with outcomes. RESULTS: A total of 251 patients were included, of which 43 (17%) received NPWT and 26 (10.4%) developed SSIs. Baseline demographics and clinicopathologic characteristics were similar between the two groups with some exceptions: Patients who received NPWT had a higher Peritoneal Carcinomatosis Index (median 19 vs. 11, p = 0.002) and operative time (10 vs. 8.2 h, p = 0.003) but were less likely to undergo HIPEC (84% vs. 95%, p < 0.05). After entropy balancing, on multivariable logistic regression, NPWT was not associated with 90-day SSI (odds ratio = 0.90; 95% confidence interval = 0.21-3.80; p = 0.89). CONCLUSION: NPWT was not associated with a reduction in SSIs. These findings prompt a reevaluation of the routine use of NPWT in CRS/HIPEC.

Impact of Tracheostomy Status on Sternal Wound Infections in Children Following Median Sternotomy.

OBJECTIVE: Sternal wound infection (SWI) is a rare but potentially life-threatening complication in children following sternotomy. Risk factors include young age, extended preoperative hospitalization, and prolonged ventilatory support. Few studies have explored the impact of pre-existing tracheostomy on SWI in pediatric patients. The purpose of this study is to measure the effect of tracheostomy and other factors on SWI in children undergoing sternotomy. STUDY DESIGN: Retrospective cohort study of a 12 year period. SETTING: Tertiary children's hospital. METHODS: Children with a tracheostomy prior to sternotomy (TPS) were identified and matched by age, height, and weight to children who underwent sternotomy alone. Demographics, medical comorbidities, surgical details, SWI diagnosis and management information, and surgical outcomes were collected. RESULTS: We identified 60 unique individuals representing 80 sternotomies. The incidence of SWI was 22.5% (n = 9) in children with a tracheostomy and 2.5% (n = 1) in those without. The incidence of SWI was greater in children with a tracheostomy (90% vs 10% in those without, P = .007) and underlying pulmonary disease (90% vs 10% in those without, P = .020). Infections in the TPS group also demonstrated greater frequency of Pseudomonas aeruginosa (n = 3) and polymicrobial growth (n = 2). CONCLUSION: The risk of developing a SWI in children undergoing sternotomy is significantly greater in those with a tracheostomy and underlying pulmonary disease. Further study is needed to understand other contributing factors and ways to mitigate this risk.

Wound healing after intracutaneous vs. staple-assisted skin closure in lumbar, non-instrumented spine surgery: a multicenter prospective randomized trial.

PURPOSE: Superficial surgical site infection (SSSI) is a prominent problem in spine surgery. Intracutaneous sutures and staple-assisted closure are two widely used surgical techniques for skin closure. Yet, their comparative impact on wound healing and infection rates is underexplored. Our goal was to address this gap and compare wound healing between these two techniques. METHODS: This study was a multicenter international prospective randomized trial. Patient data were prospectively collected at three large academic centers, patients who underwent non-instrumented lumbar primary spine surgery were included. Patients were intraoperatively randomized to either intracutaneous suture or staple-assisted closure cohorts. The primary endpoint was SSSI within 30 days after surgery according to the wound infection Centers for Disease Control and Prevention (CDC) classification system. RESULTS: Of 207 patients, 110 were randomized to intracutaneous sutures and 97 to staple-assisted closure. Both groups were homogenous with respect to epidemiological as well as surgical parameters. Two patients (one of each group) suffered from an A1 wound infection at the 30-day follow up. Median skin closure time was faster in the staple-assisted closure group (198 s vs. 13 s, p < 0,001). CONCLUSION: This study showed an overall low superficial surgical site infection rate in both patient cohorts in primary non instrumented spine surgery.

Breaking Boundaries in Spinal Surgery: GPT-4's Quest to Revolutionize Surgical site Infection Management.

BACKGROUND: Surgical site infection (SSI) is a common and costly complication in spinal surgery. Identifying risk factors and preventive strategies is crucial for reducing SSIs. GPT-4 has evolved from a simple text-based tool to a sophisticated multimodal data expert, invaluable for clinicians. This study explored GPT-4's applications in SSI management across various clinical scenarios. METHODS: GPT-4 was employed in various clinical scenarios related to SSIs in spinal surgery. Researchers designed specific questions for GPT-4 to generate tailored responses. Six evaluators assessed these responses for logic and accuracy using a 5-point Likert scale. Inter-rater consistency was measured with Fleiss' kappa, and radar charts visualized GPT-4's performance. RESULTS: The inter-rater consistency, measured by Fleiss' kappa, ranged from 0.62 to 0.83. The overall average scores for logic and accuracy were 24.27±0.4 and 24.46±0.25 on 5-point Likert scale. Radar charts showed GPT-4's consistently high performance across various criteria. GPT-4 demonstrated high proficiency in creating personalized treatment plans tailored to diverse clinical patient records and offered interactive patient education. It significantly improved SSI management strategies, infection prediction models, and identified emerging research trends. However, it had limitations in fine-tuning antibiotic treatments and customizing patient education materials. CONCLUSIONS: GPT-4 represents a significant advancement in managing SSIs in spinal surgery, promoting patient-centered care and precision medicine. Despite some limitations in antibiotic customization and patient education, GPT-4's continuous learning, attention to data privacy and security, collaboration with healthcare professionals, and patient acceptance of AI recommendations suggest its potential to revolutionize SSI management, requiring further development and clinical integration.

Frailty and the incidence of surgical site infection after total hip or knee arthroplasty: A meta-analysis.

BACKGROUND: Surgical site infection (SSI) remains a critical postoperative complication after total hip and knee arthroplasty (THA and TKA). Frailty, a condition characterized by decreased physiological reserve and increased vulnerability to stressors, may influence the risk of SSI in these patients. This meta-analysis aims to evaluate the association between frailty and the incidence of SSI following THA or TKA. METHODS: A systematic search of databases including PubMed, EMBASE, Web of Science, Wanfang, and CNKI was conducted to identify relevant studies. Data were extracted and pooled using a random-effects model to calculate the overall risk ratio (RR) and 95 % confidence intervals (CIs). RESULTS: A total of ten studies comprising 1,036,787 patients met the inclusion criteria. The meta-analysis revealed that frail patients undergoing THA or TKA had a significantly higher risk of developing SSI compared to non-frail patients (RR = 1.64, 95 % CI: 1.39-1.93, p < 0.001, I2 = 66 %). Subgroup analyses indicated that the type of arthroplasty (hip vs. knee) and the method of frailty assessment did not significantly alter the association. Further subgroup analysis suggested that frailty was significantly associated with a higher incidence of deep SSI including joint infection (RR = 1.77, 95 % CI: 1.27-1.48, p < 0.001), but not the incidence of superficial SSI (RR = 1.57, 95 % CI: 0.45-5.42, p = 0.48). The association between frailty and SSI remains in subgroup of multivariate studies only (RR = 1.56, 95 % CI: 1.34 to 1.80, p < 0.001). CONCLUSIONS: Frailty is a potential predictor of SSI following TKA/THA.

Wound Irrigation in the Prevention of Surgical Site Infection in Elective Colorectal Surgery: A Retrospective Cohort Study.

Background Surgical site infection in colon surgery is associated with significant cost and increased length of hospital stay. Recently, there has been interest in the use of pulsed lavage to reduce the risk of surgical site infection in contaminated wounds. Although increasingly used and gaining popularity, its effectiveness in elective colorectal surgery has been poorly documented. This study aimed to investigate the incidence of surgical site infection within 30 days of elective colorectal surgery in patients who underwent wound irrigation with pulse lavage versus standard closure. Methodology A retrospective study was conducted at a university hospital over a two-year period between January 2020 and December 2021. All adult patients who underwent elective colorectal surgery were eligible for inclusion. Results A total of 222 patients underwent elective colorectal surgery during the study period. Operative procedures included abdominoperineal resections, left and right hemicolectomies, pelvic exenterations, small bowel or large bowel resections, as well as stoma reversals, formations, and refashioning. In total, 76 patients underwent pulse lavage while 146 did not. The total number of surgical site infections was 39 during the study period. Infection rates in the pulse lavage group were 14.47% compared to 19.18% in the standard closure group. The chi-square analysis concluded the difference in infection rates was not statistically significant (p = 0.213). Conclusions The findings demonstrated a difference in infection rates of almost 5% favouring the pulse lavage group; however, it did not reach a statistical difference. Although infection rates were in keeping with those described in the literature, further studies in the form of randomized controlled trials should be performed to determine the benefits, if any, of pulse lavage in colorectal surgery.

Effectiveness of pharmacist-led antimicrobial stewardship programs in perioperative settings: A systematic review and meta-analysis.

OBJECTIVE: We sought to characterize and evaluate the effectiveness of pharmacist-led AMS interventions in improving antimicrobial use and subsequent surgical site infections (SSI) in perioperative settings. METHODS: A systematic review and meta-analysis was conducted by searching PubMed, Embase and CINAHL. Two independent reviewers extracted the data using the Descriptive Elements of Pharmacist Intervention Characterization Tool and undertook quality assessment using the Crowe Critical Appraisal. A meta-analysis was conducted using a random-effect model. RESULTS: Eleven studies were included in this review. Pharmacists were found to have various roles in AMS, including educational sessions, ward rounds, audits and feedback, and guidelines development. The discussion of interventions lacked details on the development. A meta-analysis revealed that pharmacist-led AMS programs in perioperative settings was associated with a significant improvement in antibiotic selection (OR 4.29; 95 % CI 2.52-7.30), administration time (OR 4.93; 95 % CI 2.05-11.84), duration (OR 5.27; 95 % CI 1.58-17.55), and SSI (OR 0.51; 95 % CI 0.34-0.77). CONCLUSION: Pharmacist-led AMS programs were effective in improving antimicrobial prescribing while reducing SSI; however most studies were of moderate quality. Studies lacked the utilization of theory to develop interventions, therefore, it is not clear whether theory-derived interventions are more effective than those without a theoretical element. High-quality, multicomponent, theory-derived, interventional studies using appropriate methodology and standardized data collection, are needed.

Surgical site infection surveillance in knee and hip arthroplasty: optimizing an algorithm to detect high-risk patients based on electronic health records.

BACKGROUND: Surgical site infection (SSI) is an important cause of disease burden and healthcare costs. Fully manual surveillance is time-consuming and prone to subjectivity and inter-individual variability, which can be partly overcome by semi-automated surveillance. Algorithms used in orthopaedic SSI semi-automated surveillance have reported high sensitivity and important workload reduction. This study aimed to design and validate different algorithms to identify patients at high risk of SSI after hip or knee arthroplasty. METHODS: Retrospective data from manual SSI surveillance between May 2015 and December 2017 were used as gold standard for validation. Knee and hip arthroplasty were included, patients were followed up for 90 days and European Centre for Disease Prevention and Control SSI classification was applied. Electronic health records data was used to generate different algorithms, considering combinations of the following variables: ≥1 positive culture, ≥ 3 microbiological requests, antimicrobial therapy ≥ 7 days, length of hospital stay ≥ 14 days, orthopaedics readmission, orthopaedics surgery and emergency department attendance. Sensitivity, specificity, negative and predictive value, and workload reduction were calculated. RESULTS: In total 1631 surgical procedures were included, of which 67.5% (n = 1101) in women; patients' median age was 69 years (IQR 62 to 77) and median Charlson index 2 (IQR 1 to 3). Most surgeries were elective (92.5%; n = 1508) and half were hip arthroplasty (52.8%; n = 861). SSI incidence was 3.8% (n = 62), of which 64.5% were deep or organ/space infections. Positive culture was the single variable with highest sensitivity (64.5%), followed by orthopaedic reintervention (59.7%). Twenty-four algorithms presented 90.3% sensitivity for all SSI types and 100% for deep and organ/space SSI. Workload reduction ranged from 59.7 to 67.7%. The algorithm including ≥ 3 microbiological requests, length of hospital stay ≥ 14 days and emergency department attendance, was one of the best options in terms of sensitivity, workload reduction and feasibility for implementation. CONCLUSIONS: Different algorithms with high sensitivity to detect all types of SSI can be used in real life, tailored to clinical practice and data availability. Emergency department attendance can be an important variable to identify superficial SSI in semi-automated surveillance.

Implementing an Internal Audit: Evaluating Hand Scrub Compliance in a Tertiary Care Hospital.

Background Aseptic protocol adherence and sterilization are the most important factors in a patient's satisfactory recovery after surgery. The standard hand scrubbing procedure helps control infection and keeps the surgical site clean by adhering to aseptic principles. Methods Thirty-six young residents and house officers participated in this prospective audit after ethical clearance was obtained. The World Health Organization (WHO) standard criteria were adhered to both before and after the intervention. Participants were observed in the surgical operation theatre (OT) without prior notice to ensure hand hygiene compliance before surgical procedures. The intervention included a video presentation as well as a live demonstration. Results Only 64.41% (n=23) of residents and house officers followed the recommended standard hand hygiene procedures before the intervention. This percentage rose to 93.92% (n=33) following the intervention, suggesting a noteworthy improvement. Conclusion Significant changes in the acceptance rates for the essential requirements of hand hygiene were observed after the evaluation in the second cycle. Adhering to WHO guidelines for procedures will help reduce the risk of infections and promote awareness of asepsis in practice.

Study protocol of the FRENCH24-ANIS study: postoperative anti-infective strategy following pancreaticoduodenectomy in patients with preoperative biliary stents-an intergroup FRENCH-ACHBT-SFAR prospective randomized controlled trial.

BACKGROUND: Despite advances in surgical techniques and care, pancreatoduodenectomy (PD) continues to have high morbidity and mortality rates. Complications such as sepsis, hemorrhage, pulmonary issues, shock, and pancreatic fistula are common postoperative challenges. A key concern in PD outcomes is the high incidence of infectious complications, especially surgical site infections (SSI) and postoperative pancreatic fistula (POPF). Bacteriobilia, or bile contamination with microorganisms, significantly contributes to these infections, increasing the risk of early postoperative complications. The occurrence of SSI in patients who undergo hepatobiliary and pancreatic (HPB) surgeries such as PD is notably higher than that in patients who undergo other surgeries, with rates ranging from 20 to 55%. Recent research by D'Angelica et al. revealed that, compared to cefoxitin, piperacillin/tazobactam considerably lowers the rate of postoperative SSI. However, these findings do not indicate whether extending the duration of antibiotic treatment is beneficial for patients at high risk of bacterial biliary contamination. In scenarios with a high risk of SSI, the specific agents, doses and length of antibiotic therapy remain unexplored. The advantage of prolonged antibiotic prophylaxis following PD has not been established through prospective studies in PD patients following biliary drainage. METHODS: This is an intergroup FRENCH-ACHBT-SFAR multicenter, open-labelled randomized, controlled, superiority trial comparing 2 broad-spectrum antibiotic (piperacillin/tazobactam) treatment modalities to demonstrate the superiority of 5-day postoperative antibiotic therapy to antibiotic prophylaxis against the occurrence of surgical site infections (SSI) following pancreaticoduodenectomy in patients with preoperative biliary stents. The primary endpoint of this study is the overall SSI rate, defined according to the ACS NSQIP, as a composite of superficial SSI, deep incisional SSI, and organ/space SSI. In addition, we will analyze overall morbidity, antibiotic resistance profiles, the pathogenicity of bacteriological and fungal cocontamination, the impact of complications after bile drainage and neoadjuvant treatment on the bacteriological and fungal profile of biliculture and cost-effectiveness. CONCLUSION: This FRENCH24-ANIS study aims to evaluate 5-day post-operative antibiotic therapy combined with antibiotic prophylaxis on the occurrence of surgical site infections (SSI) following pancreaticoduodenectomy in patients with preoperative biliary stents. TRIAL REGISTRATION: ClinicaTrials.gov number, NCT06123169 (Registration Date 08-11-2023); EudraCT number 2021-006991-18; EUCT Number: 2024-515181-14-00.

Does hydrogen peroxide help mitigate the incidence of Cutibacterium acnes in cervical spine surgeries?

Background: Surgical site infection (SSI) is a common yet serious complication of cervical spine surgery. While initially thought to be clinically insignificant, Cutibacterium acnes (C. acnes) is an important cause of infection. The purpose of this study was to investigate the ability of a hydrogen peroxide (H2O2) application during standard presurgical skin preparation to reduce the burden of C. acnes in patients undergoing cervical spine surgery. Methods: This was a retrospective review of prospectively collected data. Subjects were randomly assigned to either standard surgical preparation plus H2O2 (experimental) or without H2O2 (control). Prescrub, postscrub, and dermal cultures were obtained to assess the C. acnes burden after cultures on an aerobic and anaerobic growth medium were held for 21 days. Multivariate analysis was conducted to determine factors associated with presence of C. acnes. Outcome measures included the results of intraoperative cultures and the development of a SSI within 90 days postoperatively. Results: Patients (n=86) undergoing elective 2- or 3-level fusion via anterior approach were included. Prior to application of the antiseptic solution, 65% (28/43) of the experimental cohort and 77% (33/43) of the control cohort had positive C. acnes cultures (p=.34). Following application of antiseptic solution, there were no differences in positive C. acnes culture rates between the experimental and control cohorts in the epidermal (30% vs. 28%, p=1.00) or dermal (40% vs. 42%, p=1.00) cultures. No differences in the rates of C. acnes eradication from preantiseptic to postantiseptic application occurred for epidermal (p=1.00) or dermal (p=1.00) skin layers. None of the factors were associated with positive C. acnes epidermal cultures on multivariable logistic regression analysis (p>.05). Conclusions: While there is potential for H2O2 to reduce the positive culture rate of C. acnes in cervical spine patients, no difference was seen when compared to standard surgical skin preparation.

Risk Factors for Surgical Site Infections and the Effects of Betadine Irrigation and Intrawound Vancomycin Powder on Infection Rates in Spine Tumor Surgery.

Background Surgical site infection (SSI) following spine tumor surgery results in delays in radiation therapy and the initiation of systemic treatment. The study aims to assess risk factors for SSI in malignancy-related spinal infections and rates of infection observed in a single center with the use of betadine irrigation (BI) and intrawound vancomycin powder (IVP).  Methods Spine tumor patients managed from 11/2012 to 11/2023 were identified using a surgical database (JotLogs, Efficient Surgical Apps, Portland, Maine). Inclusion criteria were patients receiving BI and IVP and alive at 30 days post-op. Exclusion criteria were patients not receiving a combination of BI and IVP due to allergies and mortality within 30 days of surgery. Patient demographics, histology, history of pre-operative and post-operative radiation treatment history, tumor location, procedure type, number of procedures per patient, SSI, wound culture results, and mortality were collected. Results One hundred two patients undergoing 130 procedures had an SSI rate of 3.85% (5/130). There were 18.6% primary and 81.4% metastatic tumors. Demographics were average age 59.5 years old (range 7-92), 60.8% male, 39.2% female, White 88.2%, Black 9.8%, and others 2%. Pre-operative radiation therapy was significantly associated with the risk of SSI (p=0.005). Percutaneous instrumentation did not lead to a significant difference in infection rates (p=0.139). There was no significant difference in infection rates between primary and metastatic tumors (p=0.58). Multivariable regression analysis revealed pre-operative radiation (OR: 18.1; 95%CI: 1.9-172.7; p=0.009) as the statistically significant independent risk factor. Conclusions Pre-operative radiation therapy remains a risk factor for SSI. However, percutaneous instrumentation did not lead to SSI, and there was no significant difference in infection rates between primary and metastatic tumors. SSI rate was 3.85% in patients who had a combination of BI and IVP in spine tumor surgery.

Perioperative Supplemental Oxygen for the Prevention of Surgical Site Infection After Cesarean Section: A Systematic Review of Existing Literature.

Initial systematic reviews demonstrated the reduction of surgical site infection (SSI) following perioperative oxygen supplementation. SSI among colorectal surgeries was reduced by more than 50% with high-flow oxygen. However, recent randomized trials are coming up with conflicting results. The objective of this review was to comprehend whether the application of perioperative supplemental oxygen decreased the hazard of SSI following cesarean delivery. The initial search identified 95 studies. After screening title and abstracts 59 studies were included, and 33 studies were found to be relevant after checking eligibility. After a careful analysis, five articles were found fit for this systematic review. Extracted information included study design and methodology, the cumulative incidence of post-cesarean SSI following supplemental oxygen, the odds ratio, and associated variability for all factors considered in univariate and/or multivariate analysis. The cumulative incidence of the standard care group and supplemental oxygen group were comparable in all five studies with statistically significant differences. The secondary outcomes such as hospital readmission, wound separation, and intravenous antibiotics were similar in both groups as stated in the two studies. The rate of SSI in diabetics was 6.9% and 14.4% in the standard care group and supplemental oxygen group, respectively, as analyzed in a study. An increase in intra-operative blood loss was found to be the major risk factor leading to SSI. In one of the studies, Caucasian race, increased basal metabolic index, and prolonged surgery were associated with increased risk of SSI. There was no difference in neonatal umbilical artery pH resulting from supplemental oxygen during cesarean. The available literature is quite sufficient to prove that supplemental oxygen offers no added benefit in reducing post-cesarean SSI. Hence, we do not recommend its use for this purpose.

Vacuum Sealing Drainage against Surgical Site Infection after Intracranial Neurosurgery.

Background: Surgical site infections (SSIs) remain a conundrum for neurosurgeons. This study examines the efficacy and outcome of vacuum sealing drainage (VSD) in the treatment of pyogenic SSIs following intracranial neurosurgery. Methods: Twenty patients with SSIs, who received surgical intervention, were treated retrospectively with VSD during the past five years. Primary surgical procedure types, SSI types, VSD replacements, pathogenic germs, antibiotic therapy, and infection control were reviewed and discussed. Results: Of the 20 infections, 13 (65%) were extradural and 7 (35%) were extradural SSIs combined with intracranial infections (including 5 meningitis, 1 subdural abscess, and 1 brain abscess). All the patients consented to medical device implantation (including 5 titanium webs, 6 bone flap fixation devices, and 12 duraplasties), most of which were removed during debridement. The median duration from primary surgical procedure to an SSI diagnosis was 19 days (range: 7 to 365 d). All the patients also agreed to debridement and VSD treatment; VSD was replaced 0 to 5 times (median, one time) every 4 to 7 days and kept for 4 to 35 days (median, 14 d). Seven (35%) patients had defined bacterial infections, with Staphylococcus aureus being the dominant infection. The deployed standard VSD and antibiotic treatment ensured full recovery from SSIs, including from intracranial infections: 14 (70%) patients had recovered fully by follow-up, and no infection-associated death was registered; 6 (30%) patients died of severe primary affections. Conclusion: VSD-assisted therapy is safe and effective against SSIs after intracranial neurosurgery.

Reusable Surgical Headwear has a Reduced Carbon Footprint and Matches Disposables Regarding Surgical Site Infection: A Systematic Review and Meta-Analysis.

BACKGROUND: Surgical headwear is designed to maintain sterility and prevent microbial contamination. However, the environmental impact of the healthcare industry carries an obligation to develop sustainable alternatives. We aim to explore the environmental impact and safety of reusable surgical headwear. METHODS: A systematic review and meta-analysis were performed using MEDLINE, Embase, Scopus, Google Scholar, PubMed, and the Cochrane Library until December 10, 2023. Studies were reviewed for suitability and risk of bias using the ROBINS-I tool, with the results aggregated using Review Manager Version 5.4 for odds ratios (ORs) and 95% confidence intervals (CIs), and the I2 was used to assess heterogeneity. RESULTS: This systematic review included nine studies, and the meta-analysis included six studies involving 45,708 procedural cases. There was no significant difference in surgical site infection (SSI) rates between the reusable and disposable groups (OR: 0.79; 95% CI: 0.59-1.07; P = 0.13). Policy implementation did not affect SSI rates (OR: 1.21; 95% CI: 0.85-1.73; P = 0.30). Reusable surgical head covers demonstrated a significantly lower carbon footprint (P < 0.001), ozone depletion (P < 0.005), fossil fuel depletion (P < 0.005), terrestrial acidification (P < 0.005), and fine particulate matter formation (P < 0.005) than disposable alternatives. CONCLUSION: Reusable surgical headwear matches disposable options for SSI incidence and offers environmental advantages. These findings support a shift towards reusable alternatives in healthcare, aligning patient safety with ecological responsibility. By adopting reusable alternatives, healthcare systems can actively contribute to planetary health, thereby highlighting the significant role of sustainable practices in modern medical settings.

Effect of Perioperative Blood Transfusion on Complications Following Emergency Non-trauma Laparotomy in Mulago Hospital: A Prospective Cohort Study.

Background Although blood transfusion may be required during emergency non-trauma laparotomy, several retrospective cohort studies have identified blood transfusion as a significant predictor of postoperative infections and mortality. However, no study has explored such an association in a resource-limited setting. This study aims to determine the effect of perioperative blood transfusion on the 30-day risk of surgical site infections (SSIs) and mortality among patients undergoing emergency non-trauma laparotomy in a large urban tertiary hospital in a resource-limited setting. Methodology In this prospective, single-center, cohort study, we recruited 160 consecutive adult patients admitted to the general surgery wards 48 hours after emergency non-trauma laparotomy. We grouped them based on transfusion exposure status. Transfusion exposure and possible confounders were recorded on entry, while the presence or absence of SSIs and mortality were obtained over 30 days of follow-up. The data were analyzed using Epi Info version 7 and Stata version 14. P-values <0.05 indicated statistical significance. Results All 160 participants recruited, 28 (17.5%) transfusion-exposed and 132 (82.5%) non-exposed, were included in the final analysis. Transfusion exposure (relative risk = 8.16; 95% confidence interval (CI) = 2.73-24.37; p < 0.001) was an independent risk factor for SSI after multivariate logistic regression analysis adjusted for confounders. Inverse probability weighting with regression adjustment (IPWRA) revealed that transfusion exposure significantly increased the incidence of SSI by 36.2% (95% CI = 14.2%-58.2%; p = 0.001). Furthermore, transfusion exposure (hazard ratio (HR) = 3.62; 95% CI = 1.28-10.27; p = 0.015) and age ≥60 years (HR = 5.97; 95% CI = 1.98-18.01; p = 0.002) were independent risk factors for 30-day mortality after multivariate Cox regression analysis adjusted for confounders. IPWRA revealed that transfusion exposure significantly increased the incidence of mortality by 17.6% (95% CI = 1.4%-33.8%; p = 0.033). Conclusions This study suggests an independent association between perioperative blood transfusion and the occurrence of SSIs and mortality among patients undergoing emergency non-trauma laparotomy. A larger multicenter prospective cohort study considering more confounders and the use of established restrictive transfusion protocols is recommended.
