Fracture-Related Infection-Epidemiology, Etiology, Diagnosis, Prevention, and Treatment. DEUTSCHES ARZTEBLATT INTERNATIONAL 2024; 121:17-24. [PMID: 37970721 PMCID: PMC10916768 DOI: 10.3238/arztebl.m2023.0233] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/11/2023] [Revised: 10/23/2023] [Accepted: 10/23/2023] [Indexed: 11/17/2023]
Abstract
BACKGROUND Fracture-related infection (FRI) is a challenge to physicians and other workers in health care. In 2018, there were 7253 listed cases of FRI in Germany, corresponding to an incidence of 10.7 cases per 100 000 persons per year. METHODS This review is based on pertinent publications retrieved from a search in PubMed with the search terms "fracture," "infection," "guideline," and "consensus." Aside from the primary literature, international guidelines and consensus recommendations were evaluated as well. RESULTS FRI arise mainly from bacterial contamination of the fracture site. Staphylococcus aureus is the most commonly detected pathogen. The treatment is based on surgery and antibiotics and should be agreed upon by an interdisciplinary team; it is often difficult because of biofilm formation. Treatment options include implant-preserving procedures and single-stage, two-stage, or multi-stage implant replacement. Treatment failure occurs in 10.3% to 21.4% of cases. The available evidence on the efficacy of various treatment approaches is derived mainly from retrospective cohort studies (level III evidence). Therefore, periprosthetic joint infections and FRI are often discussed together. CONCLUSION FRI presents an increasing challenge. Preventive measures should be optimized, and the treatment should always be decided upon by an interdisciplinary team. Only low-level evidence is available to date to guide diagnostic and treatment decisions. High-quality studies are therefore needed to help us meet this challenge more effectively.

Abstract
ABSTRACT The purpose of this report was to estimate the additional annual cost to the U.S. healthcare system attributable to preventable medication errors (MEs) in the operating room. The ME types were iteratively grouped by their associated harm (or potential harm) into 13 categories, and we determined the incidence of operations involving each ME category (number of operations involving each category/total number of operations): (1) delayed or missed required perioperative antibiotic (1.4% of operations); (2) prolonged hemodynamic swings (7.6% of operations); (3) untreated postoperative pain >4/10 (18.9% of operations); (4) residual neuromuscular blockade (2.9% of operations); (5) oxygen saturation <90% due to ME (1.8% of operations); (6) delayed emergence (1.1% of operations); (7) untreated new onset intraoperative cardiac arrhythmia (0.72% of operations); (8) medication documentation errors (7.6% of operations); (9) syringe swaps (5.8% of operations); (10) presumed hypotension with inability to obtain a blood pressure reading (2.2% of operations); (11) potential for bacterial contamination due to expired medication syringes (8.3% of operations); (12) untreated bradycardia <40 beats/min (1.1% of operations); and (13) other (13.0% of operations). Through a PubMed search, we determined the likelihood that the ME category would result in downstream patient harm such as surgical site infection or acute kidney injury, and the additional fully allocated cost of care (in 2021 U.S. dollars) for each potential downstream patient harm event. We then estimated the cost of the MEs across the U.S. healthcare system by scaling the number of MEs to the total number of annual operations in the United States (N = 19,800,000). The total estimated additional fully allocated annual cost of care due to perioperative MEs was $5.33 billion U.S. dollars.

Abstract
The recently published Prophylactic Antibiotic Regimens In Tumor Surgery (PARITY) trial found no benefit in extending antibiotic prophylaxis from 24 hours to five days after endoprosthetic reconstruction for lower limb bone tumours. PARITY is the first randomized controlled trial in orthopaedic oncology and is a huge step forward in understanding antibiotic prophylaxis. However, significant gaps remain, including questions around antibiotic choice, particularly in the UK, where cephalosporins are avoided due to concerns of Clostridioides difficile infection. We present a review of the evidence for antibiotic choice, dosing, and timing, and a brief description of PARITY, its implication for practice, and the remaining gaps in our understanding.

Prophylactic use of incisional negative pressure wound therapy for the prevention of surgical site occurrences in general surgery: Consensus document. Surgery 2023; 173:1052-1059. [PMID: 36588049 DOI: 10.1016/j.surg.2022.11.033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 11/22/2022] [Accepted: 11/22/2022] [Indexed: 01/01/2023]
Abstract
BACKGROUND Surgical site occurrences pose a threat to patient health, potentially resulting in significant increases in health care spending caused by using additional resources. The objective of this study was to reach a consensus among a group of experts in incisional negative pressure wound therapy to determine the indications for using this type of treatment prophylactically and to analyze the associated risk factors of surgical site occurrences in abdominal surgery. METHODS A group of experts in incisional negative pressure wound therapy from Spain and Portugal was formed among general surgery specialists who frequently perform colorectal, esophagogastric, or abdominal wall surgery. The Coordinating Committee performed a bibliographic search to identify the most relevant publications and to create a summary table to serve as a decision-making protocol regarding the use of prophylactic incisional negative pressure wound therapy based on factors related to the patient and type of procedure. RESULTS The patient risk factors associated with surgical site occurrence development such as age, immunosuppression, anticoagulation, hypoalbuminemia, smoking, American Society of Anesthesiologists classification, diabetes, obesity, and malnutrition were analyzed. For surgical procedure factors, surgical time, repeated surgeries, organ transplantation, need for blood transfusion, complex abdominal wall reconstruction, surgery at a contaminated site, open abdomen closure, emergency surgery, and hyperthermic intraperitoneal chemotherapy were analyzed. CONCLUSION In our experience, this consensus has been achieved on a tailored set of recommendations on patient and surgical aspects that should be considered to reduce the risk of surgical site occurrences with the use of prophylactic incisional negative pressure wound therapy, particularly in areas where the evidence base is controversial or lacking.

The Effect of Local Administration of Vancomycin Suspended in Fibrin Glue for Prevention of Surgical Site Infection After Spinal Instrumentation: Comparison by Probability of Treatment Weighting Model. Spine (Phila Pa 1976) 2023; 48:384-390. [PMID: 36728797 DOI: 10.1097/brs.0000000000004561] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Accepted: 12/10/2022] [Indexed: 02/03/2023]
Abstract
STUDY DESIGN A retrospective cohort study. OBJECTIVE To compare the surgical site infection (SSI) rate in patients undergoing spinal instrumentation surgery who received vancomycin suspended in fibrin glue at the surgical site and those who did not. SUMMARY OF BACKGROUND DATA The intrawound application of vancomycin powder for preventing SSI after spinal surgery remains controversial. Vancomycin suspended in fibrin glue is another option for local administration that may be effective. The present study assessed whether vancomycin suspended in fibrin glue could prevent SSI after spinal instrumentation surgery. MATERIALS AND METHODS We enrolled patients who underwent posterior spinal instrumentation surgery with or without fusion for degenerative conditions, spinal trauma, or tumor. A multiple logistic regression model with inverse probability of treatment weighting based on propensity score was used to assess the efficacy of vancomycin suspended in fibrin glue and to account for confounding. A secondary multivariate logistic regression analysis was performed to identify the risk factors associated with SSI. RESULTS Of the 264 patients enrolled in this study, 134 underwent application of vancomycin suspended in fibrin glue at the surgical site and 130 did not. The incidence of SSI was lower in patients who were treated with vancomycin suspended in fibrin glue (2.2% vs. 8.5%) even after inverse probability of treatment weighting adjustment (adjusted odds ratio: 0.25; 95% CI, 0.0768-0.91; P =0.03). Multivariate logistic regression analysis showed that the treatment with vancomycin suspended in fibrin glue was significantly associated with a lower odds of SSI (odds ratio: 0.2; 95% CI, 0.05-0.85; P =0.03). CONCLUSIONS The administration of vancomycin suspended in fibrin glue was significantly associated with a lower likelihood of SSI in patients undergoing spinal instrumentation surgery.

Abstract
Introduction Surgical site infections (SSIs) are common and carry a significant risk of morbidity and mortality and lead to increased healthcare costs. Perioperative antibiotic prophylaxis decreases the risk of SSIs. There are several guidelines on the use of perioperative antibiotic prophylaxis. The American College of Surgeons (ACS) recommends weight-based antibiotic administration within 60 minutes prior to (two hours for vancomycin/fluoroquinolones) incision and redosing by drug half-life. There are limited data regarding adherence to existing recommendations. Furthermore, there are scarce data on the relationship between adherence to recommendations and the risk of postoperative SSI. Objectives In this study, we aimed to assess the adherence to ACS guidelines for perioperative antimicrobial prophylaxis in the Seattle Children's Hospital (SCH) National Surgical Quality Improvement Program (NSQIP) pediatric cohort and to determine whether adherence to ACS guidelines is associated with a decreased risk of SSI. the secondary objective was to identify risk factors associated with SSI in our patient population. Materials and methods We conducted a secondary analysis of an institutional NSQIP pediatric data cohort between Jan 1, 2012, and Dec 31, 2017. We calculated summary statistics to assess adherence to ACS recommendations and fit a logistic regression model to identify factors associated with the risk of SSI. Patients who did not receive antibiotic prophylaxis were excluded. Results A total of 6,072 surgeries among 5,532 patients met the inclusion criteria. Adherence was achieved for weight-based dosing in 35% of surgeries, administration prior to the incision in 91%, administration within 60 minutes (two hours for vancomycin/fluoroquinolones) in 86%, correct redosing in 97%, and to all recommendations in 29%. There were no significant associations between any adherence metrics and SSI, although confidence intervals were wide for some metrics. Factors associated with SSI when adherence was met included urgent case status, wound class 2 or 4, the American Society of Anesthesiologists (ASA) class 2-5, and surgery duration. Conclusion There was varying adherence to ACS recommendations on antibiotic prophylaxis in our cohort. More evidence is needed to better understand the effects of adherence to any or all components of the recommendations on SSI. We identified a group of pediatric patients at risk of SSI and a need for further research and targeted interventions.

Abstract
Background Increased demand for arthroplasty also increases the number of complications of arthroplasty, especially surgical site infection (SSI). One of the effective strategies in preventing surgical site infection is the use of appropriate prophylactic antibiotics. Objective To identify and analyse information from clinical studies regarding factors affecting the effectiveness of prophylactic antibiotics in arthroplasty patients. Methods A scoping review was conducted through the PubMed, Scopus, and Google Scholar databases within a publication range from January 2004 to August 2020. Study data are extracted and analysed by a minimum of two reviewers. Results The search results found 2.419 articles, with 39 articles were included for further analysis. Cefazolin monotherapy was the most frequently studied antibiotic (15 articles) followed by vancomycin monotherapy (8 articles). Most widely used antibiotics in arthroplasty were cefazolin mono-therapy (997.599 procedures with SSI incidence range: 0,20–16,05%) followed by vancomycin mono-therapy (125.170 procedures with SSI incidence range: 0.27–3,88%) The correct antibiotic dose has a lower percentage of the SSI than the wrong antibiotic dose. Meanwhile, administration of antibiotics within single dose or <24 h had a lower SSI percentage than administration of antibiotics >24 h. Administration antibiotics before incision also have a lower SSI percentage than after incision. There were no studies that discussed re-dosing of antibiotics in this scoping review. Conclusions There is still a need for further research related to the duration and specific timing of first dose of prophylactic antibiotics, especially regarding single dose or multiple dose antibiotics to obtain maximum effectiveness of antibiotic prophylaxis

Abstract
OBJECTIVE The aim of this study was to determine the effect of preoperative surgical antibiotic prophylaxis (SAP) with additional intraoperative redosing compared to single-dose preoperative surgical antibiotic prophylaxis on the incidence of surgical site infections (SSI). SUMMARY BACKGROUND DATA Preoperative SAP is standard care for the prevention of SSI. During long surgical procedures, additional intraoperative redosing of SAP is advised, but there is great variability in redosing strategies and compliance rates. METHODS We performed a systematic search of MEDLINE (PubMed), Embase, CINAHL and CENTRAL on June 25th, 2021 according to PROSPERO registration CRD42021229035. We included studies that compared the effect of preoperative SAP with additional intraoperative redosing to single dose preoperative SAP (no redosing) on SSI incidence in patients undergoing any type of surgery. Two researchers performed data appraisal and extraction of summary data independently. Meta-analyses were stratified per study type. We used a generic inverse variance random-effects model to estimate a pooled odds ratio with corresponding 95% confidence intervals (CIs). RESULTS We included 2 randomized controlled trials (RCT) and 8 cohort studies comprising of 9470 patients. Pooled odds ratios for SSI in patients receiving intraoperative redosing compared to those without redosing were 0.47 (95% CI: 0.19-1.16. I2 = 36%) for RCTs and 0.55 (95% CI: 0.38-0.79, I2 = 56%) for observational cohorts. There was considerable clinical heterogeneity among antibiotics used and redosing protocols. GRADE-assessment showed overall low certainty of evidence. CONCLUSION Intraoperative redosing of SAP may reduce incidence of SSI compared to a single dose preoperative SAP in any type of surgery, based on studies with considerable heterogeneity of antibiotic regimens and redosing protocols.

Abstract
Objective: Reduction of surgical site infection. Methods: Retrospective evaluation of a surgical infection prevention program consisting of the gradual introduction of specific infection prevention methods and a surveillance system identifying and reporting on potentially preventable surgical site infections as defined by the omission of a preventive method. Setting: A university tertiary referral medical center. Results: The sequential introduction of infection prevention elements in the bundle resulted in a fluctuating rate of potentially preventable surgical site infections simultaneously with a slow, gradual reduction of the clean wound SSI rate. Conclusions: Change in a complex, multidisciplinary environment such as an inpatient surgical unit happens gradually and requires focused attention and input from all involved professionals.

Abstract
Surgical site infections (SSIs) negatively affect patients and health care organizations. We conducted a descriptive, correlational study at two hospitals that provide care to rural patients in one Midwestern state. The study purposes were to describe: types of organisms causing reportable organ/space SSIs that occurred within 30 days of an open or a laparoscopic abdominal surgery (N = 20), and commonalities in patient- and care-related factors to provide baseline information for site-level prevention efforts for quality improvement. We identified Escherichia coli in almost half of the SSI cases (n = 9, 45%). Common patient-related factors included ethnicity, smoking, and dirty or contaminated wounds. Common care-related factors included longer surgery times (> 60 minutes), unplanned surgeries, and procedures that involved the colon or small bowel. Personnel can use site-level data to monitor prevalent types of organisms causing SSIs, enabling an evidence-based, interdisciplinary approach to develop and test methods to enhance prevention.

Abstract
OBJECTIVE Postoperative intra-abdominal infection is one of the most serious complications after pancreatic resection. In this article, we investigated the relationship between serum lactate level and postoperative infection, to suggest a new predictor of potential infection risk after pancreatectomy. METHODS A retrospective analysis of 156 patients who underwent pancreatic surgery and admitted in the intensive care unit for recovery after surgery between August 2017 and August 2019 was performed. RESULTS The basic characteristics, preoperative information, pathological diagnoses, surgical methods, and intraoperative situations of patients in the postoperative intra-abdominal infection group (n = 52) and non-infection group (n = 104) showed no significant differences. With the same postoperative treatments and results of fluid balance, blood pressure maintenance, and laboratory tests, postoperative serum lactate level increased much higher in the infection group than non-infection group (P < 0.001), while the base excess level declined much lower (P = 0.002). Patients in the infection group needed more time to elute lactate (P < 0.001), and stayed longer in the intensive care unit after surgery (P = 0.007). The overall postoperative complications were certainly more in the infection group (P < 0.001), resulting in a longer hospitalization time (P < 0.001). CONCLUSIONS When patients recovered smoothly from anesthesia with a stable hemodynamics situation and normal results of laboratory tests, abnormally high serum lactate level could be a predictor of postoperative intra-abdominal infection after pancreatic resection.

Abstract
BACKGROUND It remains unclear whether the benefits of performing perioperative allogeneic red blood cell (RBC) transfusion outweigh the risks of postoperative wound infection. The aim of this study was to assess the impact of perioperative RBC transfusion as well as dose-response relationship on wound infections in surgical patients in a large cohort. METHODS As a retrospective observational study, the national Hospital Quality Monitoring System database was used to retrieve information about in-hospital surgical patients without limitations on surgical types in the People's Republic of China between 2013 and 2018. Patients were divided into the perioperative RBC transfusion and non-RBC transfusion groups, and wound infection rates (the primary end point) were compared. Secondary end points included in-hospital mortality, nosocomial infections, and length of hospital stay. Furthermore, patients who underwent RBC transfusion were subdivided into 6 groups based on the volume of transfused RBCs to investigate the dose-response relationship between RBC transfusions and wound infections. The association between RBC transfusion and patient outcomes were analyzed using multivariable logistic regression models adjusted for potential confounders. RESULTS A total of 1,896,584 patients from 29 provinces were included, among whom 76,078 (4.0%) underwent RBC transfusions; the overall wound infection rate was 0.7%. After adjusting for confounding factors, perioperative RBC transfusion was associated with higher odds of wound infection (odds ratio [OR] = 2.24, 95% confidence interval [CI], 2.09-2.40; P < .001). As the volume of transfused RBCs increased, so did the odds of wound infection with a clear dose-response relationship (OR of >0 and ≤1 U, >1 and ≤2 U, >2 and ≤4 U, >4 and ≤8 U, >8 U transfusion compared with no RBC transfusion were 1.20, 95% CI, 0.76-1.91; 1.27, 95% CI, 1.10-1.47; 1.70, 95% CI, 1.49-1.93; 2.12, 95% CI, 1.83-2.45 and 3.65, 95% CI, 3.13-4.25, respectively). RBC transfusion was also found to be associated with higher odds of in-hospital mortality, nosocomial infection, and longer hospital stay. CONCLUSIONS RBC transfusion was associated with an increased odd of postoperative wound infection in surgical patients, and a significant dose-related relationship was also observed. While there are still essential confounders not adjusted for and the results do not necessarily indicate a causal relationship, we still recommend to lessen perioperative blood loss and optimize blood conservation strategies.

Abstract
BACKGROUND The incidence of surgical site infection (SSI) in colorectal surgery (CRS) is higher than other forms of general surgery. Post-operative hyperglycaemia causes increased SSI in CRS. Post-operative hyperglycaemia control in cardiac surgery reduces SSI. The aim was to evaluate using a cohort comparison the effect of post-operative glycaemic control using an insulin infusion on SSI in CRS. METHODS Collection of data for the ACS-NSQIP was commenced in 2015. The CRS unit added post-operative glycaemic control to the SSI bundle in late 2016. The intervention was an insulin infusion to titrate blood glucose between 135 and 180 mg/Dl (7.5 and 10 mmol/l). The effect of glycaemic control on SSI was assessed comparing ACS-NSQIP raw data prior and after the intervention was commenced. RESULTS The NSQIP data from July 2015 to June 2016 revealed the incidence of SSI were 25%. From January 2017 to December 2017, there was a significant reduction in SSI to 6.1% (OR = 517 Cl = 1.92-16.08, p < 0.001). The incidence of organ/space SSI fell significantly from 13% to 1.0% (OR = 11.35, Cl = 1.62-488.7, p < 0.001). There was non-significant reduction in superficial SSI from 11 to 4.0% (OR = 2.93, Cl = 0.68-13.03, p = 0.06). There was no significant difference in other factors associated with SSI in CRS. CONCLUSION Post-operative glycaemic control in CRS reduces the rate of SSI. Post-operative glycaemic control should be included in SSI bundles for CRS and may be of benefit in other surgical specialties.

Abstract
BACKGROUND Long-duration surgery requires repeated administration of antimicrobial prophylaxis (amp). Amp "redosing" reduces incidence of surgical site infections (SSI) but is frequently omitted. Clinical relevance of redosing timing needs to be investigated. Here, we evaluated the effects of compliance with amp redosing and its timing on SSI incidence in prolonged duration surgery. METHODS Data from >9000 patients undergoing visceral, trauma, or vascular surgery with elective or emergency treatment in two tertiary referral Swiss hospitals were analyzed. All patients had to receive amp preoperatively and redosing, if indicated. Antibiotics used were cefuroxime (1.5 or 3 g, if weight >80 kg), or cefuroxime and metronidazole (1.5 and 0.5 g, or 3 and 1 g doses, if weight >80 kg). Alternatively, in cases of known or suspected allergies, vancomycin (1 g), gentamicin (4 mg/Kg), and metronidazole or clindamycin (300 mg) with or without ciprofloxacin (400 mg) were used. Association of defined parameters, including wound class, ASA scores, and duration of operation, with SSI incidence was explored. RESULTS In the whole cohort, SSI incidence significantly correlated with duration of surgery (ρ = 0.73, p = 0.031). In 593 patients undergoing >240 min long interventions, duration of surgery was the only parameter significantly (p < 0.001) associated with increased SSI risk, whereas wound class, ASA scores, treatment areas, and emergency versus elective hospital entry were not. Redosing significantly reduced SSI incidence as shown by multivariate analysis (OR 0.60, 95% CI 0.37-0.96, p = 0.034), but exact timing had no significant impact. CONCLUSIONS Long-duration surgery associates with higher SSI incidence. Irrespective of its exact timing, amp redosing significantly decreases SSI risk.

A multifaceted quality improvement project improves intraoperative redosing of surgical antimicrobial prophylaxis during pediatric surgery. Paediatr Anaesth 2019; 29:705-711. [PMID: 31034725 DOI: 10.1111/pan.13651] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2018] [Revised: 03/12/2019] [Accepted: 04/19/2019] [Indexed: 11/28/2022]
Abstract
BACKGROUND Accurate intraoperative antibiotic redosing contributes to prevention of surgical site infections in pediatric patients. Ensuring compliance with evolving national guidelines of weight-based, intraoperative redosing of antibiotics is challenging to pediatric anesthesiologists. AIMS Our primary aim was to increase compliance of antibiotic redoses at the appropriate time and appropriate weight-based dose to 70%. Secondary aims included a subset analysis of time compliance and dose compliance individually, and compliance based on order entry method of the first dose (verbal or electronic). METHODS At a freestanding, academic pediatric hospital, we reviewed surgical cases between May 1, 2014, and October 31, 2017 requiring antibiotic redoses. After an institutional change in cefazolin dosing in May 2015, phased interventions to improve compliance included electronic countermeasures to display previous and next dose timing, an alert 5 minutes prior to next dose, and weight-based dose recommendation (September 2015). Physical countermeasures include badge cards, posting of guidelines, and updates to housestaff manual (September 2015). Statistical process control charts were used to assess overall antibiotic redose compliance, time compliance, and dose compliance. The chi-square test was used to analyze group differences. RESULTS A total of 3015 antibiotic redoses were administered during 2341 operative cases between May 1, 2014, and October 31, 2017. Mean monthly compliance with redosing was 4.3% (May 2014-April 2015) and 73% (November 2015-October 2017) (P < 0.001). Dose-only compliance increased from 76% to 89% (P < 0.001), and time-only compliance increased from 4.9% to 82% (P < 0.001). After implementation of countermeasures, electronic order entry compared with verbal order was associated with higher dose compliance, 90% vs 86% (P = 0.015). CONCLUSION This quality improvement project, utilizing electronic and physical interventions, was effective in improving overall prophylactic antibiotic redosing compliance in accordance with institutional redosing guidelines.

Abstract
Background Surgical site infection (SSI) has a high incidence in diabetic surgical patients. Preoperative antibiotic prophylaxis followed by an intraoperative re-dose was a common strategy in diabetic prolonged procedures. However, there were lacking studies on the relative benefits of this strategy on SSI. Our study aimed to clarify the effect of intraoperative re-dose of prophylactic antibiotics on SSI in diabetic patients. Methods A total of 1,840 diabetic patients with prolonged surgeries were included and Cefazolin was the only type of antibiotic prophylaxis. We assessed the relationship between intraoperative re-dose of cefazolin and 30-day incidence of SSI using a retrospective cohort study method. Results There were 361 diabetic cases with preoperative antibiotics only and 1,479 cases with pre- plus intraoperative antibiotics, in which 60 subjects suffered from SSI. Pre- plus intraoperative prophylaxis group had a lower rate of SSI in the overall and subgroup analyses when compared with preoperative only group. Operation location, combined with hypertension, poor blood glucose control, high WBC count and ASA score >2 were significantly associated with an increased risk of SSI for diabetic surgical patients (all P<0.05). Intraoperative re-dose of prophylactic antibiotics was statistically related to a lower incidence rate of SSI than preoperative prophylaxis alone (crude RR =0.47; 95% CI, 0.27-0.82; P<0.01), while the association remained significant even after adjusting the potential confounders (adjusted RR =0.51; 95% CI, 0.29-0.90; P=0.02). Conclusions For diabetic patients, intraoperative re-dose of prophylactic antibiotics may be an independent protective factor for the prevention of SSI. A specific perioperative antibiotics injection strategy should be encouraged for diabetic patients with prolonged surgeries to minimize the possibility of SSI.

The efficacy of ampicillin compared with ceftriaxone on preventing cesarean surgical site infections: an observational prospective cohort study. Antimicrob Resist Infect Control 2018; 7:13. [PMID: 29387347 PMCID: PMC5778626 DOI: 10.1186/s13756-018-0304-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2017] [Accepted: 01/15/2018] [Indexed: 01/09/2023] Open
Abstract
Background Cesarean surgical site infections (SSIs) can be prevented by proper preoperative antibiotic prophylaxis. Differences in antibiotic selection in clinical practice exist according to obstetricians’ preferences despite clear guidelines on preoperative antibiotic prophylaxis. This study aimed to compare the efficacy of ampicillin and ceftriaxone in preventing cesarean SSIs. Methods The observational prospective cohort study was conducted at a tertiary hospital in Thailand from 1 January 2007 to 31 December 2012. Propensity scores for ceftriaxone prophylaxis were calculated from potential influencing confounders. The cesarean SSI rates of the ceftriaxone group vs. those of the ampicillin prophylactic group were estimated by multilevel mixed-effects Poisson regression nested by propensity score. Results Data of 4149 cesarean patients were collected. Among these, 911 patients received ceftriaxone whereas 3238 patients received ampicillin as preoperative antibiotic prophylaxis. The incidence of incisional SSIs was (0.1% vs. 1.2%; p = 0.001) and organ space SSIs was (1.2% vs. 2.9%; p = 0.003) in the ceftriaxone group compared with the ampicillin group. After adjusting for confounders, the rate ratios of incisional and organ/space SSIs in the ceftriaxone compared with the ampicillin group did not differ (RR, 0.23; 95% CI 0.03–1.78), and (RR, 1.62; 95% CI 0.83–3.18), respectively. Conclusion These data indicate no difference exists between ampicillin and ceftriaxone to prevent SSIs after cesarean section. Ampicillin may be used as antibiotic prophylaxis in cesarean section.

Chitin Oligosaccharide (COS) Reduces Antibiotics Dose and Prevents Antibiotics-Caused Side Effects in Adolescent Idiopathic Scoliosis (AIS) Patients with Spinal Fusion Surgery. Mar Drugs 2017; 15:md15030070. [PMID: 28335413 PMCID: PMC5367027 DOI: 10.3390/md15030070] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2017] [Revised: 02/19/2017] [Accepted: 03/08/2017] [Indexed: 01/13/2023] Open
Abstract
Antibiotics are always considered for surgical site infection (SSI) in adolescent idiopathic scoliosis (AIS) surgery. However, the use of antibiotics often causes the antibiotic resistance of pathogens and side effects. Thus, it is necessary to explore natural products as drug candidates. Chitin Oligosaccharide (COS) has anti-inflammation and anti-bacteria functions. The effects of COS on surgical infection in AIS surgery were investigated. A total of 312 AIS patients were evenly and randomly assigned into control group (CG, each patient took one-gram alternative Azithromycin/Erythromycin/Cloxacillin/Aztreonam/Ceftazidime or combined daily), experiment group (EG, each patient took 20 mg COS and half-dose antibiotics daily), and placebo group (PG, each patient took 20 mg placebo and half-dose antibiotics daily). The average follow-up was one month, and infection severity and side effects were analyzed. The effects of COS on isolated pathogens were analyzed. SSI rates were 2%, 3% and 8% for spine wounds and 1%, 2% and 7% for iliac wound in CG, EG and PG (p < 0.05), respectively. COS reduces the side effects caused by antibiotics (p < 0.05). COS improved biochemical indexes and reduced the levels of interleukin (IL)-6 and tumor necrosis factor (TNF) alpha. COS reduced the antibiotics dose and antibiotics-caused side effects in AIS patients with spinal fusion surgery by improving antioxidant and anti-inflammatory activities. COS should be developed as potential adjuvant for antibiotics therapies.
