Do Hypoalbuminaemia Increase the Risk of Surgical Site Infection in Neck of Femur Fracture Patients: A Systematic Review and Meta-Analysis.

Serum albumin plays an important role in physiological and inflammatory haemostasis, and low serum levels are linked with an increased incidence of surgical site infections (SSI). Although this has been demonstrated in the spine and elective arthroplasty settings, there is a paucity of evidence with regard to the effect of low serum albumin on rates of SSI following surgery for adult patients suffering from traumatic and acute hip fractures. A systematic review was conducted using the PRISMA guidelines. Four databases were searched for randomised controlled trials (RCTs), cohort studies, and case-controlled studies. The risk of bias was assessed using the Newcastle-Ottawa Score (NOS). Data was collected and pooled using RevMan Web software. Results were reported as odds ratios (OR) with 95% confidence intervals (CI) and statistical significance of p <0.05. An inverse variance model was used in the meta-analysis. Six retrospective studies (five cohorts and one case-control) with a total of 43,059 patients were included. 45.3% (n=19 496) had low serum albumin (<3.5 g/dL). Hypoalbuminemia was associated with a significantly higher risk of any form of SSI (OR 1.25, p=0.008) and deep SSI (OR 1.76, p=0.05). There was no statistical significance between hypoalbuminemia and the incidence of superficial SSI (OR 1.06, p=0.77). Organ-space SSI was associated with hypoalbuminemia, although one study reported this with poor statistical significance (OR 8.74, p<0.054). Hypoalbuminemia increases the risk of most forms of surgical site infections, both superficial and deep. There is a weak conclusion to draw between the incidence of deep-space organ infections and low serum albumin.

Silver-coated tibial plateau leveling osteotomy implants do not improve surgical site infection rates over noncoated implants in a randomized trial in 73 canines.

To evaluate the incidence of surgical site infections (SSIs) in dogs undergoing a tibial plateau leveling osteotomy (TPLO) with silver-coated (SC) and noncoated (NC) TPLO plates. 65 dogs (73 surgical procedures). Client-owned dogs undergoing a TPLO procedure between November 2021 and May 2023 were prospectively enrolled. Dogs were randomly assigned either an SC or NC TPLO plate at the time of surgery. Follow-up was performed at 2 weeks and 8 weeks postoperatively by in-person examination, client questionnaire, or telephone interview. Dogs were followed up 100 days postoperatively for any incisional or implant complications. Among 73 stifles that underwent a TPLO, the overall SSI rate was 8.2% (6/73), with an infection rate of 14.3% (5/35) in the NC group and 2.6% (1/38) in the SC group; this difference was not significant (P = .17). Five of these infections were superficial, and only 1 deep SSI was recorded within the 100-day study period (NC group). Although no significant difference was noted between the SC and NC groups, likely due to a small sample size and overall low infection rate, there was a trend showing a higher infection rate in the NC group. No conclusions can be drawn on the impact of silver coating on deep or organ/space incisional infections due to the low incidence reported in this study (n = 1). Further investigation of SC TPLO implants in a larger and more long-term clinical study is warranted.

Incidence and risk factors associated with surgical site infection in acetabular fracture patients: An experience from north India

IntroductionNearly 5–7% of patients undergoing surgical management of acetabular fractures develop surgical site infection (SSI) which is one of the most important factors affecting the hospital stay, success of procedure and overall patient satisfaction. Systematic studies to identify the risk factors and their control could help to reduce the surgical site infection rate considerably. The present study assessed the incidence and risk factors related with SSI in patients undergoing surgical management of acetabular fractures at our center. Methods and materialsThis retrospective record review included a total of 228 adult acetabular fracture patients (≥18 years) who were managed surgically. Demographic and clinical profile of the patients was noted and cases developing SSI. Univariate and multivariate association of different demographic and clinical factors was done to identify factors significantly associated with SSI. Univariate analysis was done using chi-square test. Multivariate assessment was done using binary logistic regression. ResultsMean age of patients was 36.40 ± 14.18 years. Majority of patients were males (83.8 %). Incidence of SSI was 6.1 %. On univariate analysis, age ≥40 years, occupation service/business, fall from height, BMI >25 kg/m2, presence of associated injury, ≥48 h gap between injury and surgery, smoking and use of Kocher-Langenbeck approach for surgery were found to be significantly associated with an increased risk of SSI. However, on multivariate analysis only age >40 years (OR = 3.72; 95 % CI = 1.00–3.75; p = 0.049) and BMI>25.0 kg/m2 (OR = 0.20; 95 % CI = 0.05–0.85; p = 0.029) were the significant predictors of SSI. ConclusionsThis study identified that surgical site infection rates show a secular stagnating trend. There were almost no modifiable risk factors that could reduce this incidence, however, a strict post-operative care in patients with age >40 years and BMI>25 kg/m2 could help to change the direction of these trends.

The ACS-NSQIP Analysis of Negative Pressure Wound Therapy Following Pancreatectomy for Pancreatic Diagnoses.

Introduction Surgical site infections (SSIs) continue to be a challenging issue among patients undergoing pancreatectomy. Anecdotally, the use of negative pressure wound therapy (NPWT) following pancreatectomy for cancer has been associated with decreased SSIs. The objective of this study was to compare the postoperative outcomes of NPWT and non-NPWT for incisional wound care following distal pancreatectomy or pancreatoduodenectomy for pancreatic diagnoses using a national surgical database. Methods The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) was queried from 2005 to 2019 for patients undergoing distal pancreatectomy or pancreaticoduodenectomy for pancreatic diagnoses using primary Current Procedural Terminology (CPT) codes. The primary outcome was surgical site infection rates between NPWT and non-NPWT patient groups. Secondary outcomes include sepsis, septic shock, readmission, and reoperation. Outcomes of interest were compared using multivariate logistic regression. Results A total of 54,457 patients underwent pancreatectomy with 131 receiving NPWT. Multivariate analysis, while accounting for patient characteristics, including wound classification, showed no difference in postoperative superficial SSI, deep SSI, sepsis, septic shock, or readmission between the NPWT and non-NPWT groups. Organ space SSI was higher in the NPWT group (21% vs 12%, p=0.001). Reoperation related to procedure was also highin the NPWT group (14% vs 4.3%, p<0.001). Conclusion The use of NPWT in distal pancreatectomies and pancreatoduodenectomies is associated with increased organ space SSIs and reoperation rates, with no difference in superficial SSI, deep SSI, or readmission. This large sample study shows no significant benefit of using NPWT incisional wound care after pancreatectomy.

Analyzing the Efficacy of Metronidazole as Additional Surgical Site Infection Prophylaxis in Patients Undergoing Hysterectomy [ID 2683482

INTRODUCTION: The American College of Obstetricians and Gynecologists recommends cefazolin for antibiotic surgical prophylaxis for hysterectomy procedures. In 2018, hysterectomy surgical site infection (SSI) data at John Peter Smith Hospital demonstrated a higher proportion of anaerobic growth identified on cultures. The addition of metronidazole with cefazolin became surgical prophylaxis protocol at our institution. The purpose of the study is to compare rates of non-superficial SSI before and after the addition of metronidazole in hysterectomy procedures. METHODS: This was a retrospective cohort study of patients who underwent hysterectomy of any surgical approach from January 2015 to July 2023. The primary exposure of interest was administration of metronidazole with additional covariates including age, body mass index, diabetes, oncology status, and wound class. The association between metronidazole administration and non-superficial SSI was examined using a logistic regression model. Appropriate waiver was received from the institutional IRB. RESULTS: Two thousand five hundred thirty-four hysterectomies were included in our cohort. 1,207 (44%) cases had metronidazole administration, with 98% of those cases occurring after the antibiotic was incorporated into the protocol. Of the patients who did not receive metronidazole, 49 (3.7%) patients had a non-superficial SSI compared to 14 (1.2%) patients that had a non-superficial SSI with metronidazole administration. After adjusting for age and oncology status, patients who did not receive metronidazole had higher odds of having a SSI compared those who did (adjusted odds ratio [aOR]: 3.6; 95% CI: 1.97, 6.3; P≤.0001). CONCLUSION: The results demonstrate potential infection prevention benefit with metronidazole to patients undergoing hysterectomy, supporting the institutional prophylaxis protocol. The findings could have further implications across hospitals with similar patient populations.

Prophylactic Mesh Reinforcement for Non-Midline Incisions: A Systematic Review.

Many abdominal-pelvic surgeries utilize incisions not along the linea alba, such as transverse, laparoscopic, ostomy reversal, or ostomy formation incisions. The prevalence of ventral incisional hernias (VIH) at these sites and the efficacy of prophylactic mesh in preventing VIH remains unclear. PubMed, Embase, Scopus, and Cochrane databases were systematically reviewed from inception to September 2022. We included published randomized controlled trials (RCTs) that compared prophylactic mesh reinforcement versus no mesh. The primary outcome was the incidence of VIH at postoperative follow-up equal to or greater than 24 months. Secondary outcomes included surgical site infection (SSI) and surgical site occurrence (SSO). Of 3186 screened articles, only 3 RCTs with at least an 80% 2-year follow-up, encompassing a total of 901 patients, were included for analysis of non-midline VIH. Fifteen additional RCTs were included for analysis of secondary outcomes. The rate of parastomal hernias with prophylactic mesh was 21%, while it ranged from 44%-64% in the control group. The rate of incisional hernia after ostomy reversal with prophylactic mesh was 10%, and 16% in the control group. No clear evidence of a difference was found in rates of SSI or SSO between groups. There is limited evidence on the role of prophylactic mesh in preventing non-midline VIH. More studies at low risk for bias are needed to elucidate the balance of the long-term risks and benefits of prophylactic mesh for non-midline incisions.

Comparison of purse-string technique vs linear suture for skin closure after ileostomy reversal. A randomized controlled trial.

Protective stoma after rectal surgery has been associated with important complications. The most common is surgical site infection (SSI) high rates after stoma reversal reported in literature. Our study compared the rate of SSI of two skin closure techniques, linear closure, and purse string closure. We carried out a single center, prospective, randomized controlled trial in the Department of Colorectal Surgery of Fondazione Policlinico Campus Bio-Medico of Rome between January 2018 through December 2021, to compare LC vs PS closure of ileostomy sites. A total of 117 patients (53.84% male) with a mean age of 65.68 ± 14.33years were finally evaluated in the study. 58 patients were included in the PS group and 59 patients in the LC one. There was a marked difference in the SSI rate between the two arms of the study: 3 of 58 patients in the purse-string arm versus 11 of 59 in the control arm (p = 0.043). The outcome of cosmesis was also higher in PS, with a statistical significance (mean ± DS 4,01 ± 0,73 for PS group vs mean ± DS 2,38 ± 0,72 for LC group, p < 0,001). Our study demonstrated that the PS technique had a significantly lower incidence of stoma site SSI compared with LC technique. Our findings are in line with other randomized studies and suggest that PS closure could be considered as standard of care for wound closure after ileostomy reversal.

When Antimicrobial Treatment and Surgical Prophylaxis Collide: A Stewardship Opportunity.

Background: In 2002, the Centers for Medicare and Medicaid Services (CMS) in collaboration with the Centers for Disease Control and Prevention (CDC) established the Surgical Infection Prevention (SIP) project for the purposes of developing and standardizing quality improvement measures known to reduce the rates of post-operative surgical site infections (SSIs). Four years later the Surgical Care Improvement Project (SCIP), an expansion of SIP, was published in governmental Specifications Manual for National Inpatient Quality Measures and provided several additional initiatives applicable to the perioperative period. Central to both projects are the assurance of the timeliness, selection, and duration of peri-operative surgical prophylactic antibiotics. In support of this objective, various medical associations, such as the American Society of Health-System Pharmacists (ASHP) and the Infectious Diseases Society of America (IDSA), have developed the Clinical Practice Guidelines for Antimicrobial Prophylaxis in Surgery. To ensure compliance with quality measures, hospitals are required to report data to the Physicians Quality Reporting System, which is then reviewed by CMS for reimbursement purposes and to measure hospital performance. To maintain optimal standards of care and satisfy all core measures, it is expected that patients undergoing most categories of surgical procedures receive prophylactic antibiotics. We recognized that patients already being administered antimicrobial therapy as treatment for the condition requiring the surgery not uncommonly also were prescribed unwarranted and redundant pre-operative antibiotics. Our study was meant to quantify such antibiotic redundancy, which only risks the development of antimicrobial resistance and adverse events, to bolster our and other hospitals antimicrobial stewardship programs. Methods: A retrospective analysis of computerized hospital records over a one-month period of time (November 2022) was conducted focusing on hospital admissions that involved surgical operative procedures. Only those patients who had received a pre-operative surgical prophylactic antibiotic were included in the analysis. Results: Of the 92 surgeries that fulfilled the inclusion criteria, 38 (41.3%) were performed on patients who were already receiving therapeutic antibiotics for more than 24 hours targeted to treat the infection for which they were undergoing surgery. These included laparoscopic cholecystectomy (24), appendectomy (12), wound debridement (12), and soft tissue incision and drainage procedures (9), comprising nearly 50% of each type of these operations performed during the study time period. Conclusion: These findings demonstrate a clear opportunity to strengthen both our, and presumably other, hospitals antimicrobial stewardship programs. Together with physician education, granting the pharmacy the ability to cancel unnecessary and redundant surgical prophylactic antibiotics would conceivably be of great benefit.

Comparison of Patient Demographics and Risk of Surgical Site Infections Following Open Reduction and Internal Fixation of Trimalleolar Ankle Fractures: A Nationwide Analysis of a Private Payor

Surgical site infections (SSIs) are a notable complication following open reduction and internal fixation (ORIF) for ankle fractures. The purpose of this study was to (1) compare baseline demographics of patients who did and did not develop SSIs within 90 days following ORIF for trimalleolar ankle fractures and (2) identify risk factors associated with SSIs in this setting. A retrospective analysis from 2010 to 2020 was completed using a national administrative database. The study group consisted of patients who underwent ORIF for trimalleolar ankle fractures and developed SSIs within 90 days postoperatively. Patients without SSIs served as the comparison cohort. Baseline demographics of the two cohorts were compared utilizing Pearson's Chi-Square Analyses. A multivariate binomial logistic regression model determined the association of various comorbidities on developing SSIs in this setting. Out of a total sample of 22,118 patients, 1000 individuals (4.52%) developed SSIs. The study revealed that the SSI cohort exhibited a greater burden of comorbidities, as evidenced by significant differences in various individual comorbidities and average Elixhauser-Comorbidity Indices scores. The most strongly associated risk factors for the development of SSIs following ORIF for trimalleolar ankle fractures were peripheral vascular disease (OR: 1.53, p < .0001), diabetes mellitus (OR: 1.26, p = .0010), iron deficiency anemia (OR: 1.24, p = .0010), male sex (OR: 1.22, p = .0010), and tobacco use (OR: 1.15, p = .0010). This study identified several patient risk factors that were associated with developing SSIs after ORIF for trimalleolar ankle fractures, recognizing potential patient-directed interventions that may reduce the rate of SSIs in this setting.

Incisional Negative Pressure Wound Therapy After Revascularisation Surgery in Patients with Peripheral Arterial Disease: A Randomised Trial (PICO-Vasc Study)

This study assessed the potential benefits of using incisional negative pressure wound therapy (iNPWT) for patients undergoing revascularisation due to peripheral arterial disease. A prospective randomised controlled trial was conducted to compare the inguinal application of iNPWT vs. standard surgical dressings. Patients were enrolled from February 2021 to November 2022. A total of 133 groin incisions were randomised (66 intervention group, 67 control group). The randomisation sequence was carried out by permuted blocks and allocation assigned by opening opaque envelopes once the revascularisation procedure had finished. Wound healing and complication rates were assessed at post-operative days 5, 14, and 30. Primary and secondary endpoints were: 30 day post-operative surgical site infection (SSI) and surgical site occurrence (SSO) rates, defined as a surgical wound complication other than aSSI. Post-operative SSI was defined according to the US Centers for Disease Control and Prevention criteria. SSO included: wound dehiscence, seroma or lymphocele, haematoma, and lymphorrhagia. The study was registered at ClinicalTrials.gov database (NCT04840576) and reported according to the CONSORT guidelines. iNPWT did not modify the 30 day inguinal SSI and SSO rates (16.7% vs. 20.9% and 37.9% vs. 44.8%; p= .53, relative risk [RR] 0.999, 95% confidence interval [CI] 0.52- 1.88 and p=.42, RR 1.29, 95% CI 0.89- 1.86, respectively). It reduced the early SSO rate (19.7% vs. 35.8%; p=.044, RR 1.45, 95% CI 1.047 - 2.013) and post-operative seroma rate (4.6% vs. 19.4%; p= .014, RR 1.73, 95% CI 1.296- 2.397). There were no differences in SSI and SSO rates, although statistically significant reductions in early SSO rates and seroma were found in the intervention group.

A Quality Improvement Project to Increase Compliance With a Facility Protocol on Surgical Antimicrobial Prophylaxis.

Surgical site infections (SSIs) contribute to negative outcomes for patients and health care organizations. Compliancewith clinical practice guidelines likely can help prevent SSIs. An interdisciplinary team at a regional referral center in Michigan sought to reduce SSIs by improving compliance with the facility's preoperative antibiotic selection, dosing, timing, and redosing protocol. The interventions for the quality improvement project included adding the preprocedural antibiotics and doses to the master OR schedule; holding an education session for all preoperative nurses, intraoperative nurses, and anesthesia professionals; and posting a reference guide in the preoperative and intraoperative areas. Compliance with the facility's protocol for antibiotic selection, dosing, and timing significantly improved. However, SSI rates and compliance with redosing recommendations did not change significantly. The team decided to add the antibiotic order information to the master OR schedule permanently. The team plans to consider providing education sessions on administering preprocedural antibiotics outside the OR.

Comparing cefazolin/ metronidazole, piperacillin-tazobactam, or c efoxitin as surgical antibiotic prophylaxis in patients undergoing pancreaticoduodenectomy: A retrospective cohort study.

Preoperative antibiotic options for pancreaticoduodenectomy (PD) include cefoxitin (CX), piperacillin-tazobactam (PT), or combined cefazolin and metronidazole (CM). Recent studies suggest the superiority of PT over CX, but evidence for CM is unclear. To explore the impact of preoperative antibiotic selection (CM vs. PT and CX vs. PT) on the development of surgical site infections (SSI). Consecutive adult patients at oneinstitution who underwent PDfrom November 2017 to December 2021 and received either CM, PT, or CX preoperatively, were included. The primary outcome was SSI. Secondary outcomes included postoperative infections and clinically significant postoperative pancreatic fistula (POPF). Logistic regression models were used. Among 127 patients included in the study, PT, CM, and CX were administered in 46 (36.2%), 44 (34.6%), and 37 (29.4%) patients, respectively. There were 32 (27.1%) SSI, 20 (36.1%) infections, and 21 (22.9%) POPF events. PT use was associated with reduced risk of SSI compared to CX (OR: 0.32, 95% CI: 0.11-0.89, p = 0.03), but there was no difference as compared to CM (OR: 0.75, 95% CI: 0.27-2.13, p = 0.59). There were no differences in secondary outcomes. PT reduced SSI rates compared to CX but was no different to CM among patients undergoing PDat our center.

Plastic Wound Protector vs Surgical Gauze for Surgical Site Infection Reduction in Open GI Surgery

Surgical site infections (SSIs) are prevalent hospital-acquired infections with significant patient impacts and global health care burdens. The World Health Organization recommends using wound protector devices in abdominal surgery as a preventive measure to lower the risk of SSIs despite limited evidence. To examine the efficacy of a dual-ring, plastic wound protector in lowering the SSI rate in open gastrointestinal (GI) surgery irrespective of intra-abdominal contamination levels. This multicenter, patient-blinded, parallel-arm randomized clinical trial was conducted from August 2017 to October 2022 at 13 hospitals in an academic setting. Patients undergoing open abdominal bowel surgery (eg, for bowel perforation) were eligible for inclusion. Patients were randomized 1:1 to a dual-ring, plastic wound protector to protect the incision site of the abdominal wall (experimental group) or a conventional surgical gauze (control group). The primary end point was the rate of SSI within 30 days of open GI surgery. A total of 458 patients were randomized; after 1 was excluded from the control group, 457 were included in the intention-to-treat analysis (mean [SD] age, 58.4 [12.1] years; 256 [56.0%] male; 341 [74.6%] with a clean-contaminated wound): 229 in the wound protector group and 228 in the surgical gauze group. The overall SSI rate in the intention-to-treat analysis was 15.7% (72 of 458 patients). The SSI rate for the wound protector was 10.9% (25 of 229 patients) compared with 20.5% (47 of 229 patients) with surgical gauze. The wound protector significantly reduced the risk of SSI, with a relative risk reduction (RRR) of 46.81% (95% CI, 16.64%-66.06%). The wound protector significantly decreased the SSI rate for clean-contaminated wounds (RRR, 43.75%; 95% CI, 3.75%-67.13%), particularly for superficial SSIs (RRR, 42.50%; 95% CI, 7.16%-64.39%). Length of hospital stay was similar in both groups (mean [SD], 15.2 [10.5] vs 15.3 [10.2] days), as were the overall postoperative complication rates (20.1% vs 18.8%). This randomized clinical trial found a significant reduction in SSI rates when a plastic wound protector was used during open GI surgery compared with surgical gaze, supporting the World Health Organization recommendation for use of wound protector devices in abdominal surgery.

Negative Pressure Wound Therapy to Reduce Surgical Site Infections after CRS/HIPEC.

Surgical site infections (SSIs) are a common cause of morbidity after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal malignancy. Negative pressure wound therapy (NPWT) has been proposed as a method to reduce the rates of SSIs; however, there is paucity in the literature on the efficacy in this population. The goal of this study was to determine whether routine use of NPWT in patients undergoing CRS/HIPEC could reduce the risk of developing SSI. We performed a retrospective before-after study to assess the rates of SSI with NPWT compared with a standard postoperative surgical dressing (SSD) in all patients undergoing CRS/HIPEC from November 2013 to December 2021 at a single tertiary care center. The primary outcome was rate of SSI. A multivariate logistic regression analysis was performed to evaluate for risk factors for SSI. A total of 178 patients were treated with CRS/HIPEC over the study period. Seventy patients had placement of SSD, and 108 patients had placement of NPWT. Rates of SSI were 11.4% (8/70) and 5.6% (6/108) in the two groups, respectively (p = 0.16). On multivariate analysis, patients treated with NPWT had a significantly lower risk of developing an SSI (OR 0.24 [0.06, 0.92], p = 0.037). Patients living >50 km from the hospital had significantly higher risk of developing SSI (OR 2.03 [1.09, 3.78], p = 0.026). These results suggest that routine use of NPWT can reduce the risk of developing an SSI in patients undergoing CRS/HIPEC for peritoneal malignancy.

The Impact of Redosing Antibiotics for Pediatric Patients Undergoing Appendectomy for Complicated Appendicitis.

Currently, there is no universally accepted, standardized protocol for pre-operative antibiotic administration in the setting of appendectomy for complicated appendicitis among pediatric patients. Strategies to mitigate surgical site infections (SSIs) must be balanced with optimal antibiotic use and exposure. We conducted a retrospective chart review to compare outcomes between patients treated pre-operatively with a single pre-operative dose of antibiotics with those who received additional antibiotics prior to laparoscopic appendectomy for complicated appendicitis between 2020 and 2022. Of 124 pediatric patients, 18% received an additional dose of pre-operative antibiotics after initial treatment dose. Surgical site infection rates between the two groups were not statistically significant (P-value = .352), thereby suggesting that redosing antibiotics closer to the time of incision may not impact SSI rates. Additional studies are necessary to make clinical recommendations.

A Bicentric, International, Retrospective Study to Assess Steelex Sternum Set for Sternal Closure in Cardiac Surgery – STERCCAS a Cohort Study

Sternal fixation with steel wires or cerclages, is the gold standard for closing a midline sternotomy, the standard incision in cardiac surgery. Rare wound complications can occur following a sternotomy wire closure. The objective of this study is to establish that the clinical efficacy of the Steelex Sternum Set is equivalent to the results documented in existing literature. The cohorts of the previously conducted OPTICABG and PREMIVALVE studies served as a foundation for the design of this retrospective, bicentric, international, single-arm study. The purpose of the study was to evaluate the clinical performance of the Steelex Sternum Set for sternal closure after coronary artery bypass grafting or cardiac valve replacement/reconstruction surgery. The primary endpoint was the incidence of a composite consisting of sternum instability, sternum dehiscence, superficial and deep sternal wound infection up to six months after surgery. A quantitative summary of the available clinical literature has been conducted for comparison purposes. There were 229 patients in total (89 PREMIVALVE and 140 OPTICABG). The combined rate of surgical site infection and sternal dehiscence/instability was 3.49%, compared to 1.5 - 20% described in the literature. Severe complications such as mortality, stroke, myocardial infarction, and mediastinitis occurred in about 0.8 - 2% of cases. The Steelex Sternum Set is a safe and appropriate method for sternal closure in a diverse patient population undergoing cardiac valve replacement and/or reconstruction, as well as coronary artery bypass graft surgery, in routine clinical settings.

Comparative study of preoperative prophylactic antibiotic versus no antibiotic in patients undergoing elective laparoscopic cholecystectomy

Introduction: Laparoscopic cholecystectomy stands as one of the most commonly performed surgical procedures worldwide, primarily indicated for symptomatic cholelithiasis and associated gallbladder diseases. Despite its minimally invasive nature, concerns persist regarding the risk of postoperative infections, which can significantly impact patient outcomes and healthcare costs. Antibiotic prophylaxis has long been considered a standard practice to mitigate this risk, yet the optimal approach remains a subject of debate. Objective: This research was aimed to elucidate the comparative effectiveness of preoperative prophylactic antibiotic versus no antibiotics in patients undergoing elective laparoscopic cholecystectomy. Methodology: We conducted a prospective comparative study at Birat Medical College Teaching Hospital from 27 November 2023 to 27 February 2024. A total of 200 patients undergoing elective laparoscopic cholecystectomy were enrolled consecutively and assigned to the no antibiotic prophylaxis group and single dose preoperative antibiotic prophylaxis group (SD) on a roll basis. The SD group received a preoperative injection of ceftriaxone (third generation of cephalosporin) (1gm) 30 minutes before the surgical procedure. Data were collected and analyzed using SPSS version 23. Results: The overall rate of SSI was 4% in our study. Five out of 100 patients who received prophylactic and 3 out of 100 patients who did not receive antibiotics developed surgical site infection(SSI). However, the difference was not statistically significant. Conclusion: Our study comparing preoperative prophylactic antibiotics versus no antibiotics in elective laparoscopic cholecystectomy patients reveals no significant association between antibiotic use and outcomes such as surgical site infections and fever.

Orthopedic postoperative infection profile and antibiotic sensitivity of 2038 patients across 24 countries – Call for region and institution specific surgical antimicrobial prophylaxis

PurposeImproper utilization of surgical antimicrobial prophylaxis frequently leads to increased risks of morbidity and mortality.This study aims to understand the common causative organism of postoperative orthopedic infection and document the surgical antimicrobial prophylaxis protocol across various institutions in to order to strengthen surgical antimicrobial prophylaxis practice and provide higher-quality surgical care. MethodsThis multicentric multinational retrospective study, includes 24 countries from five different regions (Asia Pacific, South Eastern Africa, Western Africa, Latin America, and Middle East). Patients who developed orthopedic surgical site infection between January 2021 and December 2022 were included. Demographic details, bacterial profile of surgical site infection, and antibiotic sensitivity pattern were documented. Results2038 patients from 24 countries were included. Among them 69.7 % were male patients and 64.1 % were between 20 and 60 years. 70.3 % patients underwent trauma surgery and instrumentation was used in 93.5 %. Ceftriaxone was the most common preferred in 53.4 %. Early SSI was seen in 55.2 % and deep SSI in 59.7 %. Western Africa (76 %) and Asia-Pacific (52.8 %) reported a higher number of gram-negative infections whereas gram-positive organisms were predominant in other regions. Most common gram positive organism was Staphylococcus aureus (35 %) and gram-negative was Klebsiella (17.2 %). Majority of the organisms showed variable sensitivity to broad-spectrum antibiotics. ConclusionOur study strongly proves that every institution has to analyse their surgical site infection microbiological profile and antibiotic sensitivity of the organisms and plan their surgical antimicrobial prophylaxis accordingly. This will help to decrease the rate of surgical site infection, prevent the emergence of multidrug resistance and reduce the economic burden of treatment.

COMPARISON OF SURGICAL SITE INFECTION BETWEEN DIABETIC AND NON-DIABETIC PATIENTS IN CLEAN SURGICAL PROCEDURES

Surgical site infections (SSIs) are a major concern in healthcare, especially for individuals with diabetes. Diabetes can impair wound healing and weaken the immune system, increasing the risk of SSIs. Studying SSIs in diabetic versus non-diabetic patients undergoing clean surgeries is vital for improving patient care. Objective: The primary objective of this study was to investigate the incidence of surgical site infections (SSIs) in individuals with diabetes compared to those without diabetes who underwent clean surgical procedures. Methods: After the ethical approval from the institutional review board, this comparative study was conducted at Combined Military Hospital Jhelum from July 2022 to December 2023. A consisted of people with diabetes (n=50), while Group B comprised patients who did not have diabetes (n=50). All patients were administered suitable antibiotics before surgery. Each patient received a singular intravenous dose of Ceftriaxone 1g, administered thirty minutes before initiating the initial incision. The patients were monitored for surgical site infections (SSI), defined as the presence of redness, fever, tenderness at the incision site, discharge from the surgical wound, or the development of an abscess within 28 days after surgery. Results: Most participants in both study groups underwent open ventral hernia repair procedures, 54% in group A and 58% in group B. Mean± S. D of the Hb1Ac levels of the participants in both groups was 8.46±1.16 and 4.14±1.01 (P=&lt;0.0001). 58% of participants in Group A, while 22% in Group B had surgery-associated complications (p&lt;0.0001). 30% of participants in Group A, while 10% in Group B had SSI (p&lt;0.0001). Conclusion: Individuals with diabetes are more susceptible to experiencing higher rates of surgical site infection, especially in cases of procedures that are considered clean, in comparison to individuals without diabetes.
