Abstract
STUDY DESIGN Observational Study. OBJECTIVES Surgical site infections (SSIs) are one of the major complications in spine surgery. Numerous factors that increase the risk of SSI have been widely described. However, clinical guidelines on antibiotic prophylaxis are usually common for all patients. There are no specific guidelines for patients with a high risk of infection. The aim of this paper is to create a specific protocol for patients at high risk of SSI. METHODS This is a three-cohort study using a prospective database. Risk patients are those who meet at least two of the following criteria: obesity, diabetes, reoperation and immunosuppression. Between October 2021 and April 2023, 132 patients were recruited.They were divided into three cohorts: cohort A, 46 patients, standard prophylaxis with cefazolin 2 g/8 h for 24 h; cohort B, 46 patients, cefazolin 2 g/8h and amikacin 500 mg/12 h for 24 h; cohort C, 40 patients, cefazolin 2 g/8h and amikacin 500 mg/12 h for 72 h. RESULTS There was a significant decrease in the infection rate depending on the prophylaxis (23.9% in cohort A, 8.7% in cohort B, and 2.5% in cohort C). When logistic regression models were applied and cohorts B and C were compared with A, the following results were obtained: OR of 0.30 (CI: 0.08 - 0.97; P = 0.057) and 0.08 (IC: 0.00 - 0.45; P = 0.019), respectively. CONCLUSIONS Prophylaxis with prolonged double antibiotic therapy with cefazolin and amikacin is associated with a statistically significant decrease in the rate of SSI in patients with a high risk of infection.

A 10-Year Retrospective Analysis. Orthop Surg 2024; 16:1884-1892. [PMID: 38887157 PMCID: PMC11293923 DOI: 10.1111/os.14106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2024] [Revised: 05/07/2024] [Accepted: 05/11/2024] [Indexed: 06/20/2024] Open
Abstract
OBJECTIVE Surgical site infection (SSI) after spinal surgery is still a persistent worldwide health concern as it is a worrying and devastating complication. The number of samples in previous studies is limited and the role of conservative antibiotic therapy has not been established. This study aims to evaluate the clinical efficacy and feasibility of empirical antibiotic treatment for suspected early-onset deep spinal SSI. METHODS We conducted a retrospective study to identify all cases with suspected early-onset deep SSI after lumbar instrumented surgery between January 2009 and December 2018. We evaluated the potential risks for antibiotic treatment, examined the antibiotic treatment failure rate, and applied logistic regression analysis to assess the risk factors for empirical antibiotic treatment failure. RESULTS Over the past 10 years, 45 patients matched the inclusion criteria. The success rate of antibiotic treatment was 62.2% (28/45). Of the 17 patients who failed antibiotic treatment, 16 were cured after a debridement intervention and the remaining one required removal of the internal fixation before recovery. On univariate analysis, risk factors for antibiotic treatment failure included age, increasing or persisting back pain, wound dehiscence, localized swelling, and time to SSI (cut-off: 10 days). Multivariate analysis revealed that infection occurring 10 days after primary surgery and wound dehiscence were independent risk factors for antibiotic treatment failure. CONCLUSION Appropriate antibiotic treatment is an alternative strategy for suspected early-onset deep SSI after lumbar instrumented surgery. Antibiotic treatment for suspected SSI occurring within 10 days after primary surgery may improve the success rate of antibiotic intervention. Patients with wound dehiscence have a significantly higher likelihood of requiring surgical intervention.

Abstract
The aim of this study was to re-evaluate fluoroquinolone (FQ) use in treatment by analyzing the consumption of FQ and the resistance levels of selected Gram‑negative bacilli, as well as Neisseria gonorrhoeae and Mycobacterium tuberculosis complex in EU/EEA countries and in Poland between 2016 and 2021. Data from ECDC surveillance systems EARS-Net, Euro-GASP, and the European Tuberculosis Surveillance Network were included in the description of pathogen resistance. And the ESAC-Net project for determining FQ consumption. In over half of the EU/EEA countries, the consumption of fluoroquinolones decreased in both the community sector and the hospital sector between 2016 and 2021. The prevalence of FQ-R Escherichia coli, Klebsiella pneumoniae, Acinetobacter spp., Mycobacterium tuberculosis complex, and Neisseria gonorrhoeae exceeded 20%. The prevalence of fluoroquinolone-resistant (FQ-R) Pseudomonas aeruginosa in EU/EEA countries was less than 20% except for 2017. In most EU/EEA countries, the use of FQ has reduced in last years, except for countries like Poland where FQ were an overused group of antibiotics in the treatment of various types of infections. Fluoroquinolones, as life-saving antibiotics in severe infections, should be withdrawn from empirical treatment in Poland and in countries with a high prevalence of FQ-R microorganisms.

Abstract
Significant advancements in lumbar disc herniation (LDH) management have been made in interventional pain therapy, operative therapy, peri-operative management, and cost analysis of various procedures. The present review aims to provide a concise narrative of all these topics, current trends, and possible future directions in the management of LDH. Interventional pain management using intradiscal injections often serves as a minimally invasive non-surgical approach. Surgical modalities vary, including traditional open laminectomy, microdiscectomy, endoscopic discectomy, tubular discectomy, percutaneous laser disc decompression, and transforaminal foraminotomy. Prevention of infections during surgery is paramount and is often done via a single-dose preoperative antibiotic prophylaxis. Recurrence of LDH post-surgery is commonly observed and thus mitigative strategies for prevention have been proposed including the use of annular closure devices. Finally, all treatments are well-associated with clear as well as hidden costs to the health system and society as described by billing codes and loss of patients' quality-adjusted life-years. Our summary of recent literature regarding LDH may allow physicians to employ up-to-date evidence-based practice in clinical settings and can help drive future advancements in LDH management. Future longitudinal and comprehensive studies elucidating how each type of treatments fare against different types of herniations are warranted.

Plasma concentration of prophylactic cefazolin best correlates with lean body mass measured by bioimpedance analysis in lumbar spine surgery: Results of a pilot study. J Clin Neurosci 2023; 116:55-59. [PMID: 37625221 DOI: 10.1016/j.jocn.2023.08.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Revised: 08/12/2023] [Accepted: 08/12/2023] [Indexed: 08/27/2023]
Abstract
The aim of this study was to determine the association between measures of body composition and the concentration of plasma and paraspinal muscle cefazolin. Secondly, we aimed to confirm the efficacy of our hospital dosing regimen in achieving the minimum inhibitory concentration (MIC) at the surgical site. Patients undergoing posterior-based lumbar spine surgery had body composition analysed using bioimpedance analysis. All received 2 g of cefazolin at anaesthetic induction in line with hospital guidelines. Cefazolin concentration was measured in plasma (30-minites) and muscle (30- and 60-minuites) using high-performance liquid chromatography. 20 patients were recruited (mean age 61.5 years; 12 female). Mean plasma cefazolin concentrations were 34.1 +/- 10.2 mg/L; mean muscle concentrations 44.4 +/- 18.6 mg/kg and 43.8 +/- 20.4 mg/kg at 30- and 60-minutes respectively. Univariate analysis showed significant correlation between plasma cefazolin concentration and lean mass weight, absolute body weight, height, dry lean mass, total water, total body water, extracellular and intracellular water volume. Linear regression analysis showed lean mass weight the best predictor of plasma cefazolin concentration. Muscle cefazolin concentration was dependent on the plasma concentration. Using a MIC of 2 mg/L and 2 mg/kg for Staphylococcus aureus, MIC was achieved in all samples. In summary, plasma cefazolin concentration was best predicted by lean body mass. Further work should consider the influence of body composition on antibiotic delivery in extremes of body mass index. Local hospital guidelines are effective at achieving MIC against S. aureus.

Abstract
BACKGROUND AND PURPOSE We aimed to determine whether an extended oral antibiotic prophylaxis protocol may reduce the rate of surgical site infection (SSI) in patients undergoing instrumented spinal fusion. PATIENTS AND METHODS This retrospective cohort study comprise 901 consecutive patients subjected to spinal fusion between September 2011 and December 2018 with a minimum 1-year follow-up. 368 patients operated on between September 2011 and August 2014 were administered standard intravenous prophylaxis. 533 patients operated on between September 2014 and December 2018 were administered an extended protocol with 500 mg of oral cefuroxime axetil every 12 hours (clindamycin or levofloxacin in allergic individuals) until the removal of sutures. SSI was defined following the Centers for Disease Control and Prevention criteria. The association between risk factors and the incidence of SSI was evaluated by odds ratio (OR) with a multiple logistic regression model. RESULTS The bivariate analysis showed a statistically significant association between SSI and the type of prophylaxis used ("extended"' = 1.7% vs. "standard" = 6.2%, p= 0.001), with a lower proportion of superficial SSIs with the extended regimen (0.8% vs. 4.1%, p = 0.001). The multiple logistic regression model showed an OR = 0.25 (95% confidence interval [CI] 0.10-0.53) for extended prophylaxis and an OR = 3.5 (CI 1.3-8.1) for non-beta-lactams antibiotics. CONCLUSION Extended antibiotic prophylaxis seems to be associated with a reduction in the incidence of superficial SSI in instrumented spine surgery.

Abstract
OBJECTIVES To describe the association between duration of antimicrobial prophylaxis (AMP) and 30-day surgical site infection (SSI), 7-day acute kidney injury (AKI), 90-day Clostridioides difficile infection (CDI), prolonged hospitalization, and 30-day reoperation after lumbar spine surgery for noninfectious indications, and to report adherence to current guidelines. DESIGN Survey. PARTICIPANTS AND SETTING The study cohort comprised 6,198 patients who underwent lumbar spine surgery for noninfectious indications across 137 Veterans' Health Administration surgery centers between 2016 and 2020. METHODS Used univariate and multivariate logistic regression to determine the association between type and duration of AMP with 30-day SSI, 7-day AKI, 90-day CDI, prolonged hospitalization, and 30-day reoperation. RESULTS Only 1,160 participants (18.7%) received the recommended duration of AMP. On multivariate analysis, the use of multiple prophylactic antimicrobials was associated with increased odds of 90-day CDI (adjusted odds ratio [aOR], 5.5; 95% confidence interval [CI], 1.1-28.2) and 30-day reoperation (aOR, 2.3; 95% CI, 1.2-4.4). Courses of antimicrobials ≥3 days were associated with increased odds of prolonged hospitalization (aOR,1.8; 95% CI, 1.4-2.3) and 30-day reoperation (aOR, 3.5; 95% CI, 2.2-5.7). In univariate analysis, increasing days of AMP was associated with a trend toward increasing odds of 90-day CDI (cOR, 1.4; 95% CI, 1.0-1.8 per additional day; P = .056). CONCLUSIONS Longer courses of AMP after lumbar spine surgery were associated with higher odds of CDI, prolonged hospitalization, and reoperation, but not with lower odds of SSI. However, adherence to the recommended duration of AMP is very low, hinting at a wide evidence-to-practice gap that needs to be addressed by spine surgeons and antimicrobial stewardship programs.

Abstract
PURPOSE To determine whether the published literature supports the current practice of utilizing antibiotics postoperatively in spine surgery. METHODS A systematic review from PubMed and Cochrane Central Register of Controlled trials databases was performed. Search terms used: "Antibiotic Prophylaxis"[Mesh], antibiotic*, antibacterial*, "Spine"[Mesh], "Surgical Procedures, Operative"[Mesh]. Only comparative, clinical studies were included. Those studies with surgical site infection (SSI) criteria that were not similar to the CDC definition were excluded. A meta-analysis for overall SSI was performed. A subgroup analysis was also performed to analyze the outcomes specifically on instrumented groups of patients. A random-effects model was used to calculate risk ratios (RR). Forest plots were used to display RR and 95% confidence intervals (CI). RESULTS Thirteen studies were included (four Randomized-Controlled Trials, three prospective cohorts, and six retrospective). Three different perioperative strategies were used in the selected studies: Group 1: preoperative antibiotic administration (PreopAbx) versus PreopAbx and any type of postoperative antibiotic administration (Pre + postopAbx) (n = 6 studies; 7849 patients); Group 2: Pre + postopAbx ≤ 24 h versus Pre + postopAbx > 24 h (n = 6; 1982); and Group 3: Pre + postopAbx ≤ 48 h versus. Pre + postopAbx ≤ 72 h (n = 1; 502). The meta-analysis performed on Groups 1 and 2 did not show significant effects (RR = 1.27, 95% CI = 0.77, 2.09, and RR = 0.97, 95% CI = 0.64, 1.46, respectively). CONCLUSION A meta-analysis and comprehensive review of the literature show that the routine use of postoperative antibiotics in spine surgery may not be effective in preventing surgical site infections.

Abstract
Pediatric neurosurgery is a highly specialized branch of surgery in which surgical site infections (SSIs) are potentially serious complications that can also adversely affect a good surgical outcome, compromising functional recovery and, in some cases, even putting the patient’s life at risk. The main aim of this consensus document is to provide clinicians with a series of recommendations on antimicrobial prophylaxis for neonates and children undergoing neurosurgery. The following scenarios were considered: (1) craniotomy or cranial/cranio-facial approach to craniosynostosis; (2) neurosurgery with a trans-nasal-trans-sphenoidal approach; (3) non-penetrating head injuries; (4) penetrating head fracture; (5) spinal surgery (extradural and intradural); (6) shunt surgery or neuroendoscopy; (7) neuroendovascular procedures. Patients undergoing neurosurgery often undergo peri-operative antibiotic prophylaxis, with different schedules, not always supported by scientific evidence. This consensus provides clear and shared indications, based on the most updated literature. This work has been made possible by the multidisciplinary contribution of experts belonging to the most important Italian scientific societies, and represents, in our opinion, the most complete and up-to-date collection of recommendations on the behavior to be held in the peri-operative setting in this type of intervention, in order to guide physicians in the management of the patient, standardize approaches and avoid abuse and misuse of antibiotics.

Single-dose antibiotic prophylaxis compared with multiple-dose protocol in clean pediatric neurosurgical interventions: a nonrandomized, historically controlled equivalence trial. J Neurosurg Pediatr 2021:1-8.

Abstract
OBJECTIVE Guidelines recommend antimicrobial prophylaxis (AMP) preoperatively for "clean" spinal and cranial surgeries, while dose and timing remain controversial. The use of multiple-dose AMP for such surgeries is under debate in the pediatric context. In this clinical study, the authors aimed to compare single-dose with multiple-dose prophylactic antibiotic usage in cranial and spinal neurosurgical interventions of pediatric patients. METHODS All neurosurgical patients aged 28 days to 18 years who underwent surgery at a single tertiary center were assessed. Three cohorts (noninstrumented clean spinal, noninstrumented cranial, and instrumented cranial interventions), each of which comprised two 50-patient arms (i.e., single-dose AMP and multiple-dose AMP), were included after propensity score-matched retrospective sampling and power analysis. Records were examined for surgical site infections. Using a previously published meta-analysis as the prior and 80% acceptance of equivalence (margin of OR 0.88-1.13), logistic regression was carried out for the total cohort and each subcohort and adjusted for etiology by consideration of multiple-dose AMP as reference. RESULTS The overall sample included 300 age- and sex-matched patients who were evenly distributed in 3 bi-arm cohorts. There was no statistical intercohort difference based on etiology or type of operation (p < 0.05). Equivalence analysis revealed nondiscriminating results for the total cohort (adjusted OR 0.65, 95% CI 0.27-1.57) and each of the subcohorts (noninstrumented clean spinal, adjusted OR 0.65, 95% CI 0.12-3.44; noninstrumented cranial, adjusted OR 0.52, 95% CI 0.14-2.73; and instrumented cranial, adjusted OR 0.68, 95% CI 0.13-3.31). CONCLUSIONS No significant benefit for multiple-dose compared with single-dose AMPs in any of the pediatric neurosurgery settings could be detected. Since unnecessary antibiotic use should be avoided as much as possible, it seems that usage of single-dose AMP is indicated.

Peripheral Immune Dysfunction: A Problem of Central Importance after Spinal Cord Injury. BIOLOGY 2021; 10:biology10090928. [PMID: 34571804 PMCID: PMC8470244 DOI: 10.3390/biology10090928] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/08/2021] [Revised: 09/03/2021] [Accepted: 09/10/2021] [Indexed: 12/19/2022]
Abstract
Simple Summary Spinal cord injury can result in an increased vulnerability to infections, but until recently the biological mechanisms behind this observation were not well defined. Immunosuppression and concurrent sustained peripheral inflammation after spinal cord injury have been observed in preclinical and clinical studies, now termed spinal cord injury-induced immune depression syndrome. Recent research indicates a key instigator of this immune dysfunction is altered sympathetic input to lymphoid organs, such as the spleen, resulting in a wide array of secondary effects that can, in turn, exacerbate immune pathology. In this review, we discuss what we know about immune dysfunction after spinal cord injury, why it occurs, and how we might treat it. Abstract Individuals with spinal cord injuries (SCI) exhibit increased susceptibility to infection, with pneumonia consistently ranking as a leading cause of death. Despite this statistic, chronic inflammation and concurrent immune suppression have only recently begun to be explored mechanistically. Investigators have now identified numerous changes that occur in the peripheral immune system post-SCI, including splenic atrophy, reduced circulating lymphocytes, and impaired lymphocyte function. These effects stem from maladaptive changes in the spinal cord after injury, including plasticity within the spinal sympathetic reflex circuit that results in exaggerated sympathetic output in response to peripheral stimulation below injury level. Such pathological activity is particularly evident after a severe high-level injury above thoracic spinal cord segment 6, greatly increasing the risk of the development of sympathetic hyperreflexia and subsequent disrupted regulation of lymphoid organs. Encouragingly, studies have presented evidence for promising therapies, such as modulation of neuroimmune activity, to improve regulation of peripheral immune function. In this review, we summarize recent publications examining (1) how various immune functions and populations are affected, (2) mechanisms behind SCI-induced immune dysfunction, and (3) potential interventions to improve SCI individuals’ immunological function to strengthen resistance to potentially deadly infections.

Abstract
Study design: Complete audit cycle. Introduction: To highlight the unjustified overuse of perioperative antibiotics in clean non-instrumented lumbar spinal surgeries. To convince orthopedic surgeons in a methodological way of local field comparison between common practice on the use of perioperative antibiotics prophylaxis (PAP) in clean non-instrumented lumbar spinal surgeries and the ideal practice according to “The guidelines published by North American Spine Society (NASS)”. Methods: A complete audit cycle had been done. One hundred and eight patients underwent clean non-instrumented lumbar spinal surgeries in a tertiary spine center, during the period from the 1st of April to the 31st of June 2017 (primary audit period) and during the period from the 8th of May to the 21st of November 2018 (re-audit period). Group I: audit group (n = 54) was given the usual regimen (IV first-generation cephalosporin for 1–6 days, followed by oral antibiotics, till the removal of stitches) and Group II: re-audit group (n = 54) received only the IV antibiotics for one day). The study protocol was approved by our institution’s Ethical Committee (17100582). Results: This study showed a wide gap between international standards and local prescribing practices and calls for multiple interventions to improve our practice. Out of the 108 patients, only one case (1.85%) developed surgical site infection (SSI) in the audit group (Group I). The difference in infection rates between the two groups was statistically insignificant. Conclusion: A single-day postoperative dose of antibiotics effectively prevents postoperative wound infection following non-instrumented lumbar spinal surgery and is not associated with a higher infection rate.

Abstract
BACKGROUND Cranioplasty carries a high risk of surgical site infections (SSIs) for a scheduled procedure, particularly with antibiotic-resistant bacteria. METHODS The goal of this retrospective study was to measure the effect of tailored antibiotic prophylaxis on SSIs resulting from cranioplasties. The authors collected a prospective database of cranioplasties from 2009 to 2018. Risk factors for SSI were registered, as well as infection occurring during the first year postoperatively. A new protocol was initiated in 2016 consisting of antibiotic prophylaxis tailored to the colonizing flora of the skin of the scalp and decolonization of patients who were nasal carriers of methicillin-resistant S. aureus (MRSA); infection rates were compared. RESULTS One hundred nine cranioplasties were identified, 64 in the old protocol and 45 in the new protocol. Of the 109 cranioplasties, 16 (14.7%) suffered an infection, 14 (21.9%) in the old protocol group and 2 (4.4%) in the new protocol group (OR for the new protocol 0.166, 95% CI 0.036-0.772). Multiple surgeries (OR 3.44), Barthel ≤ 70 (OR 3.53), and previous infection (OR 3.9) were risk factors for SSI. Of the bacteria identified in the skin of the scalp, 22.2% were resistant to routine prophylaxis (cefazoline). Only one patient was identified as a nasal carrier of MRSA and was decolonized. CONCLUSIONS A high percentage of bacteria resistant to routine prophylaxis (cefazoline) was identified in the skin of these patients' scalps. The use of tailored antibiotic prophylaxis reduced significantly the infection rate in this particular set of patients.

Abstract
OBJECTIVE Despite recommendations to discontinue prophylactic antibiotics after incision closure or <24 hours after surgery, prophylactic antibiotics are continued after discharge by some clinicians. The objective of this study was to determine the prevalence and factors associated with postdischarge prophylactic antibiotic use after spinal fusion. DESIGN Multicenter retrospective cohort study. PATIENTS This study included patients aged ≥18 years undergoing spinal fusion or refusion between July 2011 and June 2015 at 3 sites. Patients with an infection during the surgical admission were excluded. METHODS Prophylactic antibiotics were identified at discharge. Factors associated with postdischarge prophylactic antibiotic use were identified using hierarchical generalized linear models. RESULTS In total, 8,652 spinal fusion admissions were included. Antibiotics were prescribed at discharge in 289 admissions (3.3%). The most commonly prescribed antibiotics were trimethoprim/sulfamethoxazole (22.1%), cephalexin (18.8%), and ciprofloxacin (17.1%). Adjusted for study site, significant factors associated with prophylactic discharge antibiotics included American Society of Anesthesiologists (ASA) class ≥3 (odds ratio [OR], 1.31; 95% CI, 1.00-1.70), lymphoma (OR, 2.57; 95% CI, 1.11-5.98), solid tumor (OR, 3.63; 95% CI, 1.62-8.14), morbid obesity (OR, 1.64; 95% CI, 1.09-2.47), paralysis (OR, 2.38; 95% CI, 1.30-4.37), hematoma/seroma (OR, 2.93; 95% CI, 1.17-7.33), thoracic surgery (OR, 1.39; 95% CI, 1.01-1.93), longer length of stay, and intraoperative antibiotics. CONCLUSIONS Postdischarge prophylactic antibiotics were uncommon after spinal fusion. Patient and perioperative factors were associated with continuation of prophylactic antibiotics after hospital discharge.

Abstract
Background: While ubiquitously multi-resistant bacteria are on the rise, peri-operative antimicrobial prophylaxis in trauma and near-to-bone surgical procedures has only been changed slightly during the last 25 years. Recent clinical studies concerning the bacterial spectrum and efficacy of antimicrobial treatment in infected trauma surgical patients are rare. The aim of the study was analysis of the contemporary bacterial spectrum and its antimicrobial resistance including the assessment of the appropriateness of peri-operative antimicrobial prophylaxis with cefuroxime. Methods: Patients of a level-I academic trauma center who underwent open or arthroscopic surgery because of a recent trauma necessitating the use of bone-near metal implants were included in the study. All patients in whom a surgical site infection (SSI) had developed during six weeks post-operatively necessitating surgical debridement and had positive microbiologic culture results from an intra-operative surgical site swab were analyzed, retrospectively. In particular, age, gender, date and duration of surgical interventions, and patient's related risk factors were collected, and infecting agents and their minimum inhibitory concentration values for 34 selected antimicrobial agents were evaluated. An SSI occurring later than 6 weeks post-operatively and patients with chronic and septic wounds were excluded. Statistical analysis was performed with SPSS® (IBM, Armonk, NY). Results: There were 438 pathogens cultured in specimens from 303 enrolled patients (female = 140, male = 163). The most frequent pathogens were Staphylococcus aureus (27.1%), S. epidermidis (20.6%), Enterococcus faecalis (13.6%), Escherichia coli (5.1%), and Pseudomonas aeruginosa (3.7%) accounting for 303 isolates. Of those, 89 (29.4%) were multi-resistant. Of the S. epidermidis isolates, 79.8% (n = 71) were resistant against Oxacillin and thus against most beta-lactam antibiotic agents. Altogether, only 44.1% of the infecting organisms were susceptible to cefuroxime, the antimicrobial agent most often being used for prophylactic purposes. Conclusion: Standardized antimicrobial prophylaxis with cephalosporins has to be reconsidered critically. Multi-resistant species such as S. epidermidis are an increasing challenge in trauma operations.
