Postoperative continuation of antibiotic prophylaxis beyond 24 h is unnecessary for abdominal surgeries in children and neonates

PurposeDespite recent WHO recommendations, antibiotic prophylaxis is routinely continued for several days after surgery. We conducted a retrospective study to evaluate the safety and efficacy of antibiotic prophylaxis cessation within 24 h after abdominal surgeries MethodsWe retrospectively reviewed the charts of patients who underwent 3 representative gastrointestinal surgeries (1; transumbilical small bowel procedure for intestinal atresia or stenosis, 2; extrahepatic bile duct resection, and hepaticojejunostomy for congenital biliary dilatation, 3; stoma closure for intestinal perforation, anorectal malformation, or inflammatory bowel disease) at our institution between 2011 and 2023. The demographic data collected included age, preoperative hemoglobin level, albumin level, body mass index, and ASA class. Intraoperative and postoperative data were also collected. The patients were divided into 2 groups according to the duration of perioperative antibiotics (‘within 24 h’ and ‘beyond 24 h’), and the incidence of superficial incisional SSI (siSSI) was compared between the 2 groups in each procedure ResultsDuring the study period, 25 cases underwent transumbilical small bowel procedure, 23 cases underwent hepaticojejunostomy, and 45 cases underwent stoma closure. The preoperative care bundle including bowel preparation, cleansing, and operative procedures has not changed during the study period. First- and third-generation cephalosporins were administered to all the patients. All patients received their first single dose of antibiotics within 60 min before the skin incision. In particular, 14 patients who underwent small-bowel procedures received only a single dose. The SSI rates for small bowel procedures, hepaticojejunostomy, and stoma closure were 0%, 4.4%, and 4.4%, respectively. No SSIs were observed in any of the procedures in the 'within 24 h' group ConclusionBased on our study, we conclude that ≤24 h of postoperative continuation of antibiotic prophylaxis is sufficient for siSSI prevention in hepaticojejunostomy and stoma closure. Additionally, single-dose antibiotic prophylaxis is adequate for neonatal small bowel procedures.

Impact of long-term vs. short-term and single day vs. single dose of antibiotic prophylaxis in reducing infection rates after orthognathic surgery: a systematic review and meta-analysis.

This review was designed to examine the effect of long-term (≥2 days) vs. short-term (1 day) and single-day vs. single preoperative doses of antibiotic prophylaxis on surgical site infection (SSI) rates after orthognathic surgery. PubMed, Web of Science, Embase, and Scopus were searched for randomized controlled trials (RCTs) without any date or language restriction till 1st September 2023. SSI rates were pooled to generate risk ratio (RR). Eight RCTs comparing long-term vs. short-term and three RCTs comparing single day vs. single preoperative dose of antibiotic prophylaxis were included. Meta-analysis showed that the use of long-term antibiotic prophylaxis significantly reduced the risk of SSI after orthognathic surgery as compared to short-term antibiotics [RR:0.42 (95% CI: 0.23, 0.76) I2=0%]. Meta-analysis also noted that patients receiving a single day of antibiotic prophylaxis had significantly reduced risk of SSI as compared to those receiving only a preoperative single dose of antibiotics [RR:0.28 (95%: 0.09, 0.82) I2=0%]. Evidence from a limited number of RCTs with moderate to high risk of bias shows that two to seven days of long-term antibiotic prophylaxis reduces the risk of SSI as compared to single-day antibiotic therapy. Also, a single day of antibiotics may be more beneficial than a single pre-operative dose of antibiotic.

To study the planned surgical procedure in single-dose antibiotic prophylaxis

Background: Postoperative wound infection may be due to many causes, of which “microbial contamination” is the factor that is influenced by antibiotic administration. Since the concept of antimicrobial prophylaxis has emerged, several workers have searched for optimal antimicrobial drugs, their routes, and the timing of their administration, with the ultimate goal of achieving zero sepsis. The use of preoperative systemic antibiotics has brought down the incidence of wound infection considerably. Aims and Objectives: The aim is to identify which drug is the best option for single-dose antibiotic prophylaxis to prevent postoperative wound infection. Materials and Methods: This is a prospective study. The study was conducted in the surgical ward of J.A. Group of Hospitals, Gwalior, Madhya Pradesh, India, from May 2020 to April 2022. Patients of all sexes and ages were included in the study. Patients were divided into five groups according to a class of antibiotics. The study consisted of a total of 125 patients admitted to the surgical ward. Statistical Package for the Social Sciences–(10 systems) was applied for the study. P<0.05 was considered statistically significant. Results: A total of 125 patients were studied in five groups, depending on the antibiotics. The A, B, C, and D groups were given only a single dose of antibiotics, while group E was given a full course of antibiotics during preoperative, intraoperative, and postoperative periods. Out of 125 cases, only 5 patients had clinical and bacteriological evidence of wound sepsis in different groups of single-dose antibiotics, and one case in group E had multiple doses of antibiotic given. The wound infection rate in clean patients was 20% in ceftazidine, 12.5% with piperacillin tazobactum and cefoperazone sulbactum, and 21.1% in the multiple dose group. No infection was reported with amoxycillin-clavulanic acid. Staphylococcus, Escherichia Coli, and Klebsiella were the offending agents, and anaerobic infections were not found. Conclusion: A single dose of antibiotic prevents the suppression of normal, sensitive microbial flora, which is usually seen with multiple doses of antibiotics. In this way, it helps in keeping the patients infection-free without interfering with their naturally inherited immunological status of the patient.

Rate and predictors of blood culture positivity after antibiotic administration: a prospective single-center study.

Blood culture obtainment prior to antibiotic administration, in patients with suspected infection, is considered the best practice in international guidelines. However, there is little data regarding the effect of a single dose of antibiotics on blood culture sterilization. We conducted a prospective study, enrolling consecutive patients with suspected infection, hospitalized in an internal medicine ward between December 2019 and January 2023. Included patients had a positive blood culture prior to antibiotic administration and a set of blood cultures taken within 24 h after a single dose of antibiotics. The rate of patients with pathogen isolation after antibiotic administration was assessed. Logistic regression was performed to examine factors associated with blood culture positivity. A total of 155 patients were recruited for the study of which 131 (50.8% female 77.5 ± 13.4 years) met the inclusion criteria. The overall rate of patients with a positive blood culture after a single dose of antibiotics was 42.0% (55/131 patients). Increasing time between antibiotic administration and post-antibiotic culture was an independent predictor for blood culture sterilization (odds ratio 0.89 [95% confidence interval, 0.83-0.97; p = 0.006] for every 60 min). Blood culture volume was an independent predictor for blood culture positivity in a sensitivity analysis which included 82 patients (OR = 1.26 [95% CI 1.03-1.57] for every 1 ml increase; p = 0.024). Blood culture positivity is reduced by antimicrobial therapy but remains high after a single dose of antibiotics. If cultures are not obtained prior to antibiotic administration, they should be obtained as soon as possible afterwards.

A STUDY OF SINGLE DOSE PRE-OPERATIVE ANTIBIOTIC PROPHYLAXIS VERSUS CONVENTIONAL MULTIPLE DOSE POST OPERATIVE ANTIBIOTIC THERAPY IN INGUINAL HERNIA REPAIR SURGERY

Background: Elective inguinal hernioplasty is considered to be a clean procedure which does not require antibiotic prophylaxis but prosthetic material like polypropylene mesh is routinely used during procedure. This makes the topic debatable because the use of prosthetic material like mesh increases the risk of surgical site infection. The incidence of surgical site infection (SSI) after inguinal hernioplasty ranges from 0% to 14 % in international literature. It is also more controversial whether single dose antibiotic or conventional multiple doses of antibiotics for 5 to 7 days is effective. Hence our study aims to compare the efficacy of single dose versus multiple dose antibiotic prophylaxis in open inguinal hernioplasty Patients And Methods: A total of 120 cases of inguinal hernia admitted in Gadag Institute of Medical Sciences in the Department of general surgery underwent Lichtenstein tension free mesh hernioplasty and received either pre-op single dose or post-op multiple dose antibiotic therapy. The two groups were then compared for SSI. Conclusion: Our study shows that a single dose of antibiotics given half an hour prior to open surgery in elective uncomplicated inguinal hernia repair surgery is as effective as multiple doses of antibiotics post-operatively in preventing post-operative surgical site infection.

Single-Versus Multiple-Dose Antimicrobial Prophylaxis in Peroral Endoscopic Myotomy: A Randomized Controlled Study (SMAPP Trial).

Infections are uncommon after peroral endoscopic myotomy (POEM) procedure. However, prophylactic antibiotics are routinely administered for variable duration during peri-operative period. In this study, we aimed to determine the difference in the rate of infections between single (SD-A) and multiple doses (MD-A) antibiotic prophylaxis groups. The study was a prospective, randomized, non-inferiority trial conducted at a single tertiary care centre from Dec 2018 to Feb 2020. Eligible patients undergoing POEM were randomized into SD-A and MD-A groups. SD-A group received one dose of antibiotic (IIIrd gen cephalosporin) within 30-min of POEM. In the MD-A group, the same antibiotic was administered for a total of three days. Primary aim of the study was to determine the incidence of infections in the two groups. Secondary outcomes included incidence of fever (> 100 °F), inflammatory markers [erythrocyte sedimentation rate (ESR), c-reactive protein(CRP)], serum procalcitonin and adverse events related to antibiotics. (NCT03784365). 114 patients were randomized to SD-A (57) and MD-A (57) antibiotic groups. Mean post-POEM CRP (0.8 ± 0.9 vs 1.5 ± 1.6), ESR (15.8 ± 7.8 20.6 ± 11.7) and procalcitonin (0.05 ± 0.04 0.29 ± 0.58) were significantly higher after POEM (p = 0.001). Post-POEM inflammatory markers (ESR, CRP and procalcitonin) were similar in both the groups. Fever on day-0 (10.5% vs 14%) and day-1 (1.7% vs 3.5%) was detected in similar proportion of patients. Post-POEM infections were recorded in 3.5% (1.7% vs 5.3%, p = 0.618). Single dose of antibiotic is non-inferior to multiple dose antibiotic prophylaxis. Elevation of inflammatory markers and fever after POEM represents inflammation and does not predict infection after POEM.

Frequency of Surgical Site Infection in Mesh Repair for Inguinal Hernias

OBJECTIVES To determine the frequency of surgical site infection in mesh repair for inguinal hernias. METHODOLOGY This Descriptive observational study was carried out at the Surgical B unit of Hayatabad Medical Complex Peshawar from November 2021 to October 2022. A total of 179 patients were included in the study were given a single dose of antibiotics, i.e.1, gm Ceftriaxone, one hour before inguinal hernia mesh repair.RESULTS A total of 179 patients aged between 30-60 years with a mean age of 45 years were enrolled. There were 98(54.7%) male while 81(45.3%) females. The frequency of wound infection was noted in 23 (12.8%) patients following mesh repair for inguinal hernia. Out of 23, most of the patients, 10(43.5%) had Medical redness & tenderness, 8(34.8%) patients had pus discharge from the wound side, and 5(21.7%) patients had wound site abscesses.CONCLUSION Surgical site infection after mesh repair was higher than the internationally reported incidence. Establishing a baseline SSI rate for inguinal hernia repairs offers a useful benchmark for future studies and surgical programs in these

Safety profile of a multimodal fail-safe model to minimize postoperative complications in oncologic colorectal resections—a cohort study

BackgroundDespite innovations in surgical techniques, major complications following colorectal surgery still lead to a significant morbidity and mortality. There is no standard protocol for perioperative management of patients with colorectal cancer. This study evaluates the effectiveness of a multimodal fail-safe model in minimizing severe surgical complications following colorectal resections.MethodsWe compared major complications in patients with colorectal cancers who underwent surgical resections with anastomosis during 2013–2014 (control group) with patients treated during 2015–2019 (fail-safe group). The fail-safe group had preoperative bowel preparation and a perioperative single dose of antibiotics, on-table bowel irrigation and early sigmoidoscopic assessment of anastomosis in rectal resections. A standard surgical technique for tension-free anastomosis was adapted in the fail-safe approach. The chi-square test measured relationships between categorical variables, t-test estimated the probability of differences, and the multivariate regression analysis determined the linear correlation among independent and dependent variables.ResultsA total of 924 patients underwent colorectal operations during the study period; however, 696 patients had surgical resections with primary anastomoses. There were 427 (61.4%) laparoscopic and 230 (33.0%) open operations, while 39 (5.6%) laparoscopic procedures were converted. Overall, the rate of major complications (Dindo-Clavien grade IIIb–V) significantly reduced from 22.6% for the control group to 9.8% for the fail-safe group (p < 0.0001). Major complications mainly occurred due to non-surgical reasons such as pneumonia, heart failure, or renal dysfunction. The rates of anastomotic leakage (AL) were 11.8% (22/186) and 3.7% (n = 19/510) for the control and fail-safe groups, respectively (p < 0.0001).ConclusionWe report an effective multimodal fail-safe protocol for colorectal cancer during the pre-, peri-, and postoperative period. The fail-safe model showed less postoperative complications even for low rectal anastomosis. This approach can be adapted as a structured protocol during the perioperative care of patients for colorectal surgery.Trial registrationThis study was registered in the German Clinical Trial Register (Study ID: DRKS00023804).

A COMPARATIVE STUDY OF EFFICACY OF SINGLE DOSE PROPHYLACTIC V/S CONVENTIONAL PERIOPERATIVE ANTIBIOTIC THERAPY IN CLEAN CASES OF MESH HERNIOPLASTY

Introduction: One of the most often carried out general surgical procedures is inguinal hernia surgery. Despite the fact that open inguinal hernioplasty is one of the cleanest surgical procedures, some surgeons nevertheless provide antibiotics as a preventative measure .The present study was undertaken to compare the efcacy of the single dose prophylaxis v/s conventional perioperative operational therapy. Material And Methods: This study was a hospital based observational comparative study which was conducted in the in the Department of General surgery at Aarupadai Veedu medical college and hospital, Puducherry, A study 60 cases were included. Patients were divided into two groups. Each group consists of 30 cases of Inguinal Hernia. The study group (Group SDA) received single dose of antibiotic preoperatively while the other group (Group CA) received 3 days of empirical antibiotic therapy post operatively. After obtaining pre anaesthetic check-up patients were posted for surgery. All the cases in study group (group SA) were administered with single dose of 1.5gm of inj. Cefuroxime 30 minutes before skin incision was given. They received no further antibiotics intravenously or oral. The data was analysed using SPSS software Pvalue less then 0.05 consider as statistically signicant. Data in the form of age, gender, BMI, type of work, side of hernia, type of hernia, habit of alcohol consumption and smoking, presence of DM, hypertension, CVD, COPD, duration of surgery, immediate postop fever, nausea and vomiting were noted in prescribed format and statistical analysis was done. Conclusion: However, the SSI in the single dose antibiotic group was remarkably lower than the proportion of SSI in conventional group on post op day 7 however this difference was not substantial on day 14. Also the length of hospital stay, time taken to return to daily activities and work were substantially less in single dose antibiotic group compared to conventional group. We infer that single dose antibiotic is preferred over conventional antibiotics in inguinal hernia repair

Preoperative Prophylactic Antibiotics in Mandibular Fractures and Surgical Site Infection.

Compared with other facial fractures, mandibular fractures have the highest rate of postsurgical site infection. There is strong evidence to suggest that postoperative antibiotics do not reduce rates of surgical site infections (SSIs) regardless of duration. However, there are conflicting data in the literature regarding the role of prophylactic preoperative antibiotics in reducing rates of SSIs. This study reviews the rate of infections in patients who underwent mandibular fracture repair who received a course of preoperative prophylactic antibiotics compared with those who received no or 1 dose of perioperative antibiotics. Adult patients who underwent mandibular fracture repair at Prisma Health Richland between 2014 and 2019 were included in the study. A retrospective cohort review was conducted to determine the rate of SSI, comparing 2 groups of patients who underwent mandibular fracture repair. Patients who received more than 1 dose of scheduled antibiotics before surgery were compared with those who did not receive any antibiotic treatment before surgery or received only a single dose of antibiotics within 1 hour of incision time (perioperative antibiotics). The primary outcome was the rate of SSI between the 2 groups of patients. There were 183 patients who received more than 1 dose of scheduled antibiotics before surgery and 35 patients who received a single dose of perioperative antibiotics or did not receive any antibiotics. The rate of SSI was not significantly different in the preoperative prophylactic antibiotics group (29.3%) compared with the patients who received a single perioperative dose or no antibiotics (25.0%). Extended regimens of preoperative prophylactic antibiotics beyond a single dose at time of surgery do not reduce SSIs after surgical repair in mandibular fractures.

Is there any effect of long term alpha-adrenergic blocker and a single dose antibiotic usage in reducing febrile urinary tract infections after prostate biopsy?

Aim: To investigate whether the using long term alpha-adrenergic blockers before biopsy has an effect on preventing febrile urinary tract infections (FUI) secondary to biopsy in patients undergoing prostate biopsy due to elevated prostate specific antigen (PSA) .Material and Method: The data of 2558 patients who underwent transrectal ultrasonography-guided prostate biopsy (TRUS+BX) due to elevated PSA in our clinic between January 2008 and July 2021 were analyzed retrospectively. The patients were divided into two groups as those who used alpha-blockers for a minimum of three months or longer before biopsy (Group 1) and those who did not use alpha-blockers before applying to the outpatient clinic (Group 2) . Demographic data of the groups and post-biopsy FUI development rates were compared.Results: It was observed that 1340 (52.4%) of the patients were using alpha-blockers (Group 1) and 1218 (47.6%) did not (Group 2) . The median age of the patients in the pre-biopsy groups was similar [Group 1=68 (IQR=9) years and Group 2=68 (IQR=9) years, p=0.887]. There was no significant difference between the groups in terms of median prostate volume [Group1=57 (31) ml and Group 2=58 (34) ml, p=0.199]. The median PSA value was found to be significantly higher in Group 1 than in Group 2 [10.50 (5.40) ng/dl vs 10.35 (6.80) ng/dl, p=0.026]. Postvoid residual urine volume (PVR) was found to be significantly higher in Group 2 [Group 1=40 (30) ml and Group2=60 (90) ml, p&amp;lt;0.001]. Similarly, the frequency of FUI development after biopsy was found to be significantly higher in Group 2 [Group 1=17 (1.3%) and Group 2=65 (5.3%) , p&amp;lt;0.001].Conclusion: The use of alpha-adrenergic blockers for a minimum of three months or longer before prostate biopsy significantly reduces the incidence of FUI that may develop secondary to biopsy.

Post-Operative Infection Rate Between Single Dose Versus Multiple Dose Antibiotic Therapyin Patients Undergoing Laparoscopic Cholecystectomy

Objective: To compare the frequency of post-operative infection rate between single dose versus multiple dose antibiotic therapy in patients undergoing laparoscopic cholecystectomy.&#x0D; Study Design: Comparative prospective study.&#x0D; Place and Duration of Study: Surgical Department, Combined Military Hospital, Lahore Pakistan from Oct 2017 to Feb 2020.&#x0D; Methodology: Patients of both genders undergoing laparoscopic cholecystectomy for simple cholelithiasis were included. Group-A patients underwent laparoscopic cholecystectomy using single-dose prophylactic antibiotic therapy with 2-gram 3rd generation cephalosporin at the time of induction of anaesthesia. In contrast, Group-B patients underwent laparoscopic cholecystectomy using 2-grams of 3rd generation Cephalosporin intravenously at the time of induction of anaesthesia followed by intravenous 1-gram Ceftriaxone two doses 12 hours apart. All patients were followed up on the first postoperative day, and then 1-week and 2-week follow up were done for any surgical site infection.&#x0D; Results: Patients in Group-A had a mean age of 37.12±6.53 years, while patients in Group-B had a mean age of 37.74±6.40 years. The post-operative infection rate in Group-A (single dose antibiotic therapy) was seen in 08 (4.28%), while in Group-B (multiple dose antibiotic therapies) was seen in 18 (9.63%) patients (p-value = 0.042).&#x0D; Conclusion: This study concluded that the single-dose prophylactic antibiotic is as good as multiple-dose antibiotic therapy used as prophylaxis for the prevention of post-operative infection rate among patients with cholecystectomy done via the laparoscopic method.

The antibiotic strategies during percutaneous nephrolithotomy in China revealed the gap between the reality and the urological guidelines

BackgroundCorrect perioperative antibiotic strategies are crucial to prevent postoperative infections during percutaneous nephrolithotomy (PCNL). We aimed to compare the realistic antibiotic strategies applied in China with current urological guidelines.MethodsBetween April and May 2020, urologists from China were invited to finish an online cross-sectional survey. The questionnaire was designed according to the current urological guidelines and literatures.Results3393 completed responses were received. 61.1% (2073/3393) respondents had urological experience of more than 10 years. 72.4% urologists chose multiple-dose antibiotics for patients with both negative urine culture (UC-) and negative urine microscopy (UM-) preoperatively. Respondents in central China (OR = 1.518; 95% CI 1.102–2.092; P = 0.011), east China (OR = 1.528; 95% CI 1.179–1.979; P = 0.001) and northeast China (OR = 1.904; 95% CI 1.298–2.792; P = 0.001) were more likely to prescribe multiple-dose antibiotic for UC-UM- patients. Notably, the respondents who finished PCNL exceeded 100 cases per year were in favor of single-dose administration (OR = 0.674; 95% CI 0.519–0.875; P = 0.003). There are only 8.3% urologists chose single-dose antibiotic for UC-UM+ patients, whereas 65.5% administered antibiotics for 1–3 days. Meanwhile, for UC+ patients, 59.0% of the urologists applied antibiotics shorter than 1 week, and only 26.3% of the urologists carried out routine re-examination of UC. Moreover, postoperative antibiotics were frequently prescribed for 3–6 days (1815; 53.5%). Finally, although 88.2% urologists considered stone culture important for management of postoperative antibiotics as the guideline recommended, only 18.5% performed it routinely.ConclusionsThe antibiotic strategies are different between current practice in China and the urological guidelines. The dissimilarities suggested that further studies should be conducted to investigate the reasons of the differences and standardize the application of antibiotics.

Study Comparing Effect of Single Dose Antibiotic Prophylaxis versus Conventional Antibiotic Coverage in Clean, Elective Surgeries – A Randomized Controlled Clinical Trial

BACKGROUND&#x0D; Postoperative wound infection remains the most common complication of surgery. With the fear of developing wound infection after surgery, many surgeons administer antibiotics for 7 -10 days even in clean uncontaminated cases. This practice is not only expensive to the patients but also can lead to hospital-acquired infections. We wanted to assess the effectiveness and efficacy of single-dose antibiotics in clean elective surgical cases in this study.&#x0D; METHODS&#x0D; A prospective interventional study was conducted in the General Surgery department, SRM Medical College Research Centre, Kattankulathur for a period of 18 months between May 2018 and October 2019. In this study, 143 patients were selected according to the inclusion criteria. All the data findings were recorded and analysed.&#x0D; RESULTS&#x0D; Out of 143 patients presented with clean cases, 72 cases were included in the study group and 71 cases in the control group as per the inclusion criteria. In the present study, the incidence of postoperative infection was equal i.e., 6 % in both groups. However, the grade of infection varied. The difference was not statistically significant.&#x0D; CONCLUSIONS&#x0D; Based on my study I would like to conclude that it is recommendable to use single-dose antibiotic prophylaxis for clean surgical cases, as per the study results there is not much difference in the occurrence of SSI when compared to multiple doses.

Study of prophylactic single-dose antibiotic to prevent surgical site infection

Background: Surgical site infections (SSIs) have been linked to longer hospital stays and higher costs. Infection occurs when endogenous flora is translocated to a generally sterile site. It's also feasible to seed the surgical site with illness from afar (especially in patients with prostheses or another implant). SSIs are influenced by bacterial inoculums and pathogenicity, host defenses, preoperative care, and intraoperative management. Antibiotic prophylaxis is therefore essential to address this problem. This study to evaluate the effectiveness of single-dose antibiotic prophylaxis in preventing surgical site infection in elective surgeries.Methods: This prospective study included 50 patients receiving elective surgery at a tertiary hospital's department of general surgery. Relevant information about each patient was obtained using a Performa developed for the project. Cefuroxime was given 30 minutes before the incision, and effect on post-operative wound infection was investigated.Results: We had 50 cases in our study, predominantly males, with maximum individuals in the 41-50 years age group. Cholecystectomy cases presented with the most SSIs (20%). S. aureus was the most common causative organism of SSI in this study.Conclusions: A single preoperative dose of antibiotic cefuroxime effectively prevents surgical site infection in elective cases assuming an uncomplicated procedure.

Assessment of Bundle of Measures Perioperatively to Decrease the Incidence of Surgical Site Wound Infection in Patients Undergoing Abdominal Hysterectomies

Background: Surgical site infections (SSIs) are the second most common reason for unplanned hospital readmissions after hysterectomy and result in increased morbidity and health care costs. The estimated rate of SSI after hysterectomy varies between 1% and 4%. The objective of the study is to investigate if a bundle of perioperative measures (as stated earlier) reduces down the incidence of post-operative surgical site wound infection after abdominal hysterectomy. Materials and Methods: The present prospective study was carried out on total 200 women who were undergo hysterectomy in the operation theater of Department of Obstetrics and Gynecology of IPGMER and SSKM Hospital due to gynecological conditions requiring hysterectomy. Four perioperative bundles of measures are considered – 1. chlorhexidine gluconate and Cetrimide solution (Savlon) wash of the operative field 1 h before the operation, 2. administration of single dose antibiotic (Inj. Ceftriaxone 1 g intravenous) 1 h or less before the incision, 3. vaginal wash with povidone-iodine, and 4. sterile dressing is to be maintained and removed postoperatively after 48 h. Result: We found that in case, 94 (94.0%) patients had Ceftriaxone and 6 (6.0%) patients had clindamycin and gentamicin. In control, 96 (96.0%) patients had ceftriaxone and 4 (4.0%) patients had clindamycin and gentamicin. Association of choice of antibiotic versus group was not statistically significant (P = 0.5164). In case, 6 (6.0%) patients had wound gaping. In control, 11 (11.0%) patients had wound gaping. Association of wound gaping versus group was statistically significant (P = 0.048). Conclusion: The present study found that hospital stay was more in control compared to case which was statistically significant. Fever was more in control compared to case which was statistically significant. In this study, local wound discharge was more in control compared to case which was statistically significant. It was found that wound gaping was more in control compared to case which was statistically significant.

TO STUDY THE OUTCOME OF PATIENT UNDERGOING ELECTIVE LAPAROSCOPIC CHOLECYSTECTOMY WITH SINGLE DOSE OF ANTIMICROBIAL PROPHYLAXIS.

INTRODUCTION :- Laparoscopic cholecystectomy is very commonly performed surgery for symptomatic cholelithiasis. There is very low risk of infective complications in elective Laparoscopic cholecystectomy and hence standard guideline doesn't recommend prophylactic antibiotic usage for low risk cases. However it is very commonly practicised in dosage and duration inconsistent among various surgeons. This study is being done to assess the efcacy of single dose antibiotic prophylaxis over multiple dose in the prevention of surgical site infection in patients undergoing elective laparoscopic cholecystectomy to avoid antibiotic resistance and overuse of it . METHODS: The study included 60 patients admitted for elective Laparoscopic cholecystectomy. First 30 patients received injectable ceftriaxone 1 gram intravenous peri-operatively, rst dose twelve hour before surgery and second dose half hour before surgical incision and then followed by injection (conventional dose) ceftriaxone 1 gram/day iv twice daily for the rst 5-7 days post-operatively. Next 30 was dened as the single dose (post-operative) antibiotic patients , this group were given only single dosage of injectable ceftriaxone 1 gram intravenous post-operatively.operation-room anesthetic assistant administered prophylactic antibiotics at induction of anaesthesia to all the patients. On the third, fth, tenth and fteenth days post operatively, based on Southampton scoring system the wound was seen and grading of the infection was done RESULT: The post-operative surgical site infection rate in group receiving single dose was 7.76 % and that in multiple dose group was found to be 6.67% . Chi- square test was used to analyse the data and the difference in the rate of SSI in both the groups was found to be statistically insignicant. CONCLUSION: There is no signicant difference in the outcome of elective laparoscopic cholecystectomy in terms of post operative surgical site infection in single dose and multiple dose group. Also single dose of antibiotics are more patient compliant, cost effective, have less adverse effects and reduce the incidence of antibiotic resistance

Preoperative Antibiotics Influence Culture Yield in the Treatment of Hand, Wrist, and Forearm Infections.

We conducted a retrospective review of 470 consecutive patients who underwent debridement for a presumed acute infection of the hand, wrist, or forearm at a single tertiary care center between January 2015 and May 2020. Data including patient demographics, mechanism of infection and affected body part(s), and details of antibiotic administration, including type and timing with respect to culture acquisition, were collected. Three hundred and forty-one patients (73%) received preoperative antibiotics prior to debridement and culture acquisition. The rate of positive cultures among patients who received preoperative antibiotics was 81% compared with 95% among patients who did not receive preoperative antibiotics (p < 0.01; odds ratio, 4.73). Even a single dose of antibiotics imparted a significantly increased risk of obtaining negative intraoperative cultures, and an incremental increase in the likelihood of obtaining negative cultures was seen with each preoperative dose given up to 7 doses. We did not identify a "safe" interval of time between antibiotic administration and culture acquisition such that culture yield was not affected. Patients who received preoperative antibiotics for the treatment of upper-extremity infections were approximately 5 times more likely to have negative cultures at the time of debridement than those who did not receive preoperative antibiotics. This effect persisted regardless of the number of doses given or the interval between antibiotic administration and culture acquisition. Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Comparison of single dose versus multiple doses of antibiotic prophylaxis for prevention of surgical site infection

Background: Surgical site infection is a common problem following general surgical procedures. Despite major improvement in antibiotics, improved antiseptic measures SSI continues to present a big challenge. In this study we will compare single dose versus multiple dose antibiotic prophylaxis for prevention of SSI in clean and clean contaminated surgical wound.Methods: This is an institution based prospective, comparative study, with total 60 patients as study population. Clinical finding, wound swab culture and routine haematological reports were taken as study variables. Patients receiving single dose antibiotic and multiple dose antibiotic were included in ‘Group A’ and ‘Group B’ respectively. The surgical sites were examined from post-operative days 3 to 8 for signs of infection.Results: In This study, 46.7% patients were female, and 53.3% patients were male. In Group-A, patients having post operative fever, tachycardia and leucocytosis were 16.7%, 13.3% and 20.0% respectively. 6.7% patients had purulent and 10.0% patients had seropurulent discharge from wound. In Group-B, patients having post operative fever, tachycardia, and leucocytosis were 13.3%, 16.7% and 13.3% respectively. 6.7% patients had purulent and seropurulent discharge from wound. There is no statistically significant difference between two groups regarding post operative fever, tachycardia, leucocytosis and wound discharge.Conclusions: There is no significant difference between single dose and multiple dose antibiotic prophylaxis to prevent SSI in patients for elective clean and clean contaminated surgery however single dose is more cost effective.
