Study of the Practice of Surgical Antibiotic Prophylaxis Use for Elective Neurosurgical Cases in a Tertiary Hospital and Understanding the Rationale. World Neurosurg 2024; 189:e612-e623. [PMID: 38944194 DOI: 10.1016/j.wneu.2024.06.126] [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: 04/07/2024] [Revised: 06/22/2024] [Accepted: 06/24/2024] [Indexed: 07/01/2024]
Abstract
BACKGROUND This study aims to evaluate the adherence to surgical antibiotic prophylaxis (SAP) guidelines in elective neurosurgery and assess the impact on surgical site infection (SSI) rates in a tertiary teaching hospital in Malaysia. METHOD A retrospective review was conducted on patients who underwent elective neurosurgical procedures from January 1, 2021, to December 31, 2021, in a 1600-bed tertiary teaching hospital. The study assessed adherence to national and hospital SAP guidelines, focusing on the choice of antibiotic, dosage, timing, and duration. Additionally, a survey was conducted among neurosurgeons to evaluate their knowledge, attitudes, and practices regarding SAP. RESULT Out of 202 patients included, there was a 99% compliance rate with antibiotic choice and 69.8% with the antibiotic duration. The SSI rate was identified at 6.4%. The knowledge, attitudes, and practices survey highlighted a strong awareness of SAP guidelines among surgeons, albeit with variations in practice, particularly in antibiotic duration and choice of antibiotics. CONCLUSIONS While there is high adherence to the correct choice of antibiotic for SAP in elective neurosurgery, there are gaps in compliance with the recommended duration of antibiotic use. The study highlights the need for targeted interventions to improve adherence to SAP guidelines, which could potentially reduce the incidence of SSI in neurosurgery. Ongoing education and auditing are essential to optimize SAP practices and enhance patient outcomes in neurosurgery.

Is an Elevated Preoperative CRP Level a Predictive Factor for Wound Healing Disorders following Lumbar Spine Surgery? J Pers Med 2024; 14:667. [PMID: 39063921 PMCID: PMC11278350 DOI: 10.3390/jpm14070667] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2024] [Revised: 06/10/2024] [Accepted: 06/18/2024] [Indexed: 07/28/2024] Open
Abstract
Postoperative wound infections are a prevalent concern among the hospital-associated infections in Europe, leading to prolonged hospital stays, increased morbidity and mortality, and substantial patient burdens. Addressing the root causes of this complication is crucial, especially given the rising number of spine surgeries due to aging populations. METHODS A retrospective analysis was conducted on a cohort of 3019 patients who underwent lumbar spine surgery over a decade in our department. The study aimed to assess the predictors of wound healing disorders, focusing on laboratory values, particularly inflammatory parameters. RESULTS Of the 3019 patients, 2.5% (N = 74) experienced deep or superficial wound healing disorders, showing the significant correlation between C-reactive protein (CRP) levels and these disorders (p = 0.004). A multivariate analysis identified several factors, including age, sex, hypertension, diabetes, cardiac comorbidity, surgical duration, dural injury, and blood loss, as being correlated with wound healing disorders. CONCLUSION Demographic factors, pre-existing conditions, and perioperative variables play a role in the occurrence of adverse effects related to wound healing disorders. Elevated CRP levels serve as an indicator of increased infection risk, though they are not a definitive diagnostic tool for wound healing disorders.

Abstract
PURPOSE Surgical site infection (SSI) is a serious complication after cranioplasty. Due to the relatively frequent occurrence of post-cranioplasty SSI, the utility of autologous bone flap swab cultures surrounding cryopreservation as a reliable predictor has been the subject of an ongoing debate. This bicentric study aims to contribute to this topic by conducting an in-depth analysis of bone flaps obtained via decompressive craniectomies. This study had three major aims: assessments of 1) bacterial contamination of bone flaps after decompressive craniotomy, 2) impact of cryoconservation on contamination rates and 3) potential effectiveness of anti-infective treatment to reduce the germ load prior to cranioplasty. METHODS Cryopreserved bone flaps from two centers were used. Microbiological cultivations of swabs prior to and after cryopreservation were taken and assessed for aerobic and anaerobic growth over a 14-day incubation period. Additionally, in a subset of bone flaps, swab testing was repeated after thorough rinsing with an anti-infectant (octenidine-phenoxyethanol) followed by saline. RESULTS All 63 bone flaps (patients median age at surgery: 59 years) were obtained via decompressive craniectomies. Swabs done prior to cryopreservation revealed a 54% infection rate with Propionibacterium acnes being the most common microorganism in 65% of those cases. After thorough disinfection of the preserved bone flaps, all but one case showed no bacterial growth in swab testing. Furthermore, no relevant risk factors for bacterial contamination could be identified. CONCLUSION This retrospective study showed the common presence of bacterial growth in cryopreserved bone flaps before and after freezing. Rinsing with octenidine-phenoxyethanol and saline effectively prevented bacterial growth in a notable percentage of cases, suggesting a potential strategy to reduce contamination. However, persistent bacterial growth in some cases underscores the need for further research to optimize antiseptic measures during autologous cranioplasty.

Abstract
OBJECTIVES Single dose prophylaxis is good enough for general surgery with low risk patients. However, the evidence for the effectiveness of single dose anti-microbial prophylaxis (AMP) is not conclusive in high risk patients and spinal surgeries requiring instrumentation or the use of implants in particular. No studies have explored the various concentration of ceftriaxone in plasma and tissue as well during an ongoing spinal surgery. Therefore, the objective of study was to correlate the serum and tissue concentrations of ceftriaxone with the SSI and identify patients with increased risk of SSI. METHODS It was an open label prospective study in 50 consecutive patients who underwent elective spine surgery under prophylactic cover of ceftriaxone. Serum and tissue concentration were estimated by high pressure liquid chromatography during the ongoing surgery. RESULTS Subjects were observed for any post-operative complications including SSI. Serum (p=0.002) and tissue (p=0.012) concentrations of ceftriaxone at the closure of spinal surgery were associated with SSI. Duration of the surgery (p=0.04) and use of implants (p=0.02) were also important surgery related risk factors. CONCLUSIONS Serum and tissue concentrations of ceftriaxone at the closure and duration of surgery and instrumentation or use of implants in the spinal surgery are good predictors of SSI.

Abstract
AIMS To evaluate the effect of antibiotic prophylaxis(AP) in the prognosis of Post-neurosurgical meningitis(PNM) patients. METHODS A cohort analysis was performed using the clinical database in Beijing Tiantan Hospital and Capital Medical University. Data were collected on patients with the diagnosis of PNM (n = 3931) during 2012.01 to 2022.04. The microbial distribution, types of AP, and 42 and 90 days survival analysis of AP patients were evaluated using probable statistical methods. Independent risk factors for mortality were established by constructing a logistic regression analysis. RESULT A total of 1,190 patients were included in this study, Klebsiella pneumoniae, Acinetobacter baumannii, and Staphylococcus aureus occupied the highest proportion. Of them, 929 cases received AP, cefuroxime and ceftriaxone are the most frequent used antibiotics. In addition, We found that PNM patients without AP significantly increased the 42 days and 90 days all-cause mortality rates. The use of different levels of AP did not improve patient outcomes, and ICU admission and assisted mechanical ventilation (AMV) were identified as independent mortality risk factors for PNM patient received AP. CONCLUSIONS AP plays an important role in the prognosis of PNM patients and has a significant function in improving prognosis. The prevention of PNM with antibiotics prior to neurosurgery should be emphasized in clinical practice, and appropriate selection of antibiotics is necessary to prevent the occurrence of infection and inhibit the emergence of antibiotic-resistant bacteria.

Abstract
Robotic assistance in stereoelectroencephalography (SEEG) holds promising potential for enhancing accuracy, efficiency, and safety during electrode placement and surgical procedures. This systematic review and meta-analysis, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and International Prospective Register of Systematic Reviews (PROSPERO) registration, delves into the latest advancements and implications of robotic systems in SEEG, while meticulously evaluating outcomes and safety measures. Among 855 patients suffering from medication-refractory epilepsy who underwent SEEG in 29 studies, averaging 24.6 years in age, the most prevalent robots employed were robotic surgical assistant (ROSA) (450 patients), Neuromate (207), Sinovation (140), and ISys1 (58). A total of 8,184 electrodes were successfully implanted, with an average operative time of 157.2 minutes per procedure and 15.1 minutes per electrode, resulting in an overall mean operative time of 157.7 minutes across all studies. Notably, the mean target point error (TPE) stood at 2.13 mm, the mean entry point error (EPE) at 1.48 mm, and postoperative complications occurred in 7.69% of robotically assisted (RA) SEEG cases (60), with 85% of these complications being asymptomatic. This comprehensive analysis underscores the safety and efficacy of RA-SEEG in patients with medication-refractory epilepsy, characterized by low complication rates, reduced operative time, and precise electrode placement, supporting its widespread adoption in clinical practice, with no discernible differences noted among the various robotic systems.

Abstract
BACKGROUND Surgical site infection (SSI) is a common complication following craniotomy that increases morbidity, mortality, and medical expenses. The objectives of this study were to determine the relevant risk factors associated with SSI after elective craniotomy for brain tumor and analyse the treatments for SSI. METHODS A retrospective nested case‒control study was conducted using data from patients who underwent craniotomy for brain tumor resection at the Neurosurgical Oncology Department No. 6 of Beijing Tiantan Hospital, Capital Medical University, between January 2019 and December 2021. Risk factors for SSI were determined using multivariate logistic regression analysis. We analyzed microbiological and related treatment data for different SSI types. RESULTS Among 2061 patients who underwent craniotomy for brain tumor, 31 had SSI (1.50%). In the multivariate logistic regression analysis, body mass index (BMI) and operative duration were identified as independent risk factors for SSI. The most common microorganism isolated from SSIs was Staphylococcus epidermidis (22.9%), and drug sensitivity results showed that gram-positive bacteria were sensitive to linezolid, vancomycin and tigecycline, whereas gram-negative bacteria were sensitive to meropenem, cefepime and ceftazidime. Six of the seven patients who underwent bone flap removal due to osteomyelitis were infected with gram-negative bacteria. CONCLUSIONS BMI and operative duration were identified as independent risk factors for SSI. Diabetes mellitus, previous ratio therapy, type of incision, recurrence tumor and other risk factors were not found to be associated with the occurrence of SSI in this study.

Abstract
INTRODUCTION Controllable factors associated with surgical site infections (SSIs) have focused on reducing contamination of the surgical field with potential pathogens. The aim of this prospective study is to determine the incidence of glove contamination in a series of elective neurosurgical operations and determine the relationship of such glove contamination to subsequent SSI. We hypothesize that contamination of surgical gloves is associated with subsequent SSI. METHODS In this prospective quality improvement study, gloves of the surgical team were swabbed for standard culture just prior to wound closure of elective neurosurgical operations. Patient characteristics, surgical details, and occurrence of subsequent SSIs were collected retrospectively from the electronic medical records. Data were analyzed with χ2 with Fisher's exact test and Student's t test. RESULTS Surgical glove contamination occurred in 10 of 96 elective neurosurgical cases (10.4%). SSIs occurred in 6 cases (6.2%), but no SSI occurred in a case in which surgical glove contamination occurred (P = 1). SSI was associated with younger patient age (P = 0.0448), and surgical glove contamination was associated with less resident experience (P = 0.0354). CONCLUSIONS Surgical glove contamination identified at the time of wound closure does not correlate with the development of subsequent SSI in elective neurosurgical operations.

Abstract
Robotic assistance has improved electrode implantation precision in stereoelectroencephalography (SEEG) for refractory epilepsy patients. We sought to assess the relative safety of the robotic-assisted (RA) procedure compared to the traditional hand-guided one. A systematic search on PubMed, Web of Science, Embase, and Cochrane was performed for studies directly comparing robot-assisted vs. manually guided SEEG to treat refractory epilepsy. The primary outcomes included target point error (TPE), entry point error (EPE), time of implantation of each electrode, operative time, postoperative intracranial hemorrhage, infection, and neurologic deficit. We included 427 patients from 11 studies, of whom 232 (54.3%) underwent robot-assisted surgery and 196 (45.7%) underwent manually guided surgery. The primary endpoint, TPE, was not statistically significant (MD 0.04 mm; 95% CI - 0.21, - 0.29; p = 0.76). Nonetheless, EPE was significantly lower in the intervention group (MD - 0.57 mm; 95% CI - 1.08; - 0.06; p = 0.03). Total operative time was significantly lower in the RA group (MD - 23.66 min; 95% CI - 32.01, - 15.31; p < 0.00001), as well as the individual time of implantation of each electrode (MD - 3.35 min; 95% CI - 3.68, - 3.03; p < 0.00001). Postoperative intracranial hemorrhage did not differ between groups: robotic (9/145; 6.2%) vs. manual (8/139; 5.7%) (RR 0.97; 95% CI 0.40-2.34; p = 0.94). There was no statistically relevant difference in infection (p = 0.4) and postoperative neurological deficit (p = 0.47) incidence between the two groups. In this analysis, there is a potential relevance in the RA procedure when comparing the traditional one, since operative time, time of implantation of each electrode, and EPE were significantly lower in the robotic group. More research is needed to corroborate the superiority of this novel technique.

Abstract
PURPOSE Surgical site infections (SSIs) after neurosurgery are common in daily practice. Although numerous reports have described SSIs in neurosurgery, reports specific to gliomas are limited. This study aimed to investigate the relationship between SSIs and glioma treatment characteristics, such as reoperations, radiation therapy, and chemotherapy. METHODS We examined 1012 consecutive patients who underwent craniotomy for glioma between November 2013 and March 2022. SSIs were defined as infections requiring reoperation during the observation period, regardless of their location. We retrospectively analyzed SSIs and patient factors. RESULTS During the observation period, SSIs occurred in 3.1% (31/1012). In the univariate analysis, three or more surgeries (P = 0.007) and radiation therapy (P = 0.03) were associated with SSIs, whereas intraoperative magnetic resonance imaging (MRI) was not significantly associated (P = 0.35). Three or more surgeries and radiation therapy were significantly correlated with each other (P < .0001); therefore, they were analyzed separately in the multivariate analysis. Three or more surgeries were an independent factor triggering SSIs (P = 0.02); in contrast, radiation therapy was not an independent factor for SSIs (P = 0.07). Several SSIs localized in the skin occurred more than 1 year after surgery. CONCLUSIONS Undergoing three or more surgeries for glioma is an independent risk factor for SSIs. Glioma SSIs can occur long after surgery. These results are considered characteristic of gliomas. We recommend careful long-term observation of patients at a high risk of SSIs.

Preoperative individual-target transcranial magnetic stimulation demonstrates an effect comparable to intraoperative direct electrical stimulation in language-eloquent glioma mapping and improves postsurgical outcome: A retrospective fiber-tracking and electromagnetic simulation study. Front Oncol 2023; 13:1089787. [PMID: 36816968 PMCID: PMC9936080 DOI: 10.3389/fonc.2023.1089787] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Accepted: 01/20/2023] [Indexed: 02/05/2023] Open
Abstract
Background Efforts to resection of glioma lesions located in brain-eloquent areas must balance the extent of resection (EOR) and functional preservation. Currently, intraoperative direct electrical stimulation (DES) is the gold standard for achieving the maximum EOR while preserving as much functionality as possible. However, intraoperative DES inevitably involves risks of infection and epilepsy. The aim of this study was to verify the reliability of individual-target transcranial magnetic stimulation (IT-TMS) in preoperative mapping relative to DES and evaluate its effectiveness based on postsurgical outcomes. Methods Sixteen language-eloquent glioma patients were enrolled. Nine of them underwent preoperative nTMS mapping (n=9, nTMS group), and the other seven were assigned to the non-nTMS group and did not undergo preoperative nTMS mapping (n=7). Before surgery, online IT-TMS was performed during a language task in the nTMS group. Sites in the cortex at which this task was disturbed in three consecutive trials were recorded and regarded as positive and designated nTMS hotspots (HSnTMS). Both groups then underwent awake surgery and intraoperative DES mapping. DES hotspots (HSDES) were also determined in a manner analogous to HSnTMS. The spatial distribution of HSnTMS and HSDES in the nTMS group was recorded, registered in a single brain template, and compared. The center of gravity (CoG) of HSnTMS (HSnTMS-CoG)-based and HSDES-CoG-based diffusion tensor imaging-fiber tracking (DTI-FT) was performed. The electromagnetic simulation was conducted, and the values were then compared between the nTMS and DES groups, as were the Western Aphasia Battery (WAB) scale and fiber-tracking values. Results HSnTMS and HSDES showed similar distributions (mean distance 6.32 ± 2.6 mm, distance range 2.2-9.3 mm, 95% CI 3.9-8.7 mm). A higher fractional anisotropy (FA) value in nTMS mapping (P=0.0373) and an analogous fiber tract length (P=0.2290) were observed. A similar distribution of the electric field within the brain tissues induced by nTMS and DES was noted. Compared with the non-nTMS group, the integration of nTMS led to a significant improvement in language performance (WAB scores averaging 78.4 in the nTMS group compared with 59.5 in the non-nTMS group, P=0.0321 < 0.05) as well as in brain-structure preservation (FA value, P=0.0156; tract length, P=0.0166). Conclusion Preoperative IT-TMS provides data equally crucial to DES and thus facilitates precise brain mapping and the preservation of linguistic function.

Cancers (Basel) 2023; 15:cancers15020371. [PMID: 36672321 PMCID: PMC9856387 DOI: 10.3390/cancers15020371] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 12/20/2022] [Accepted: 12/28/2022] [Indexed: 01/08/2023] Open
Abstract
Background: For thoracoscopic lung cancer surgery, the continuous relationship and the trigger point of operative duration with a risk of adverse perioperative outcomes (APOs) and early discharge remain unknown. Methods: This study enrolled 12,392 patients who underwent this surgical treatment. Five groups were stratified by operative duration: <60 min, 60−120 min, 120−180 min, 180−240 min, and ≥240 min. APOs included intraoperative hypoxemia, delayed extubation, postoperative pulmonary complications (PPCs), prolonged air leakage (PAL), postoperative atrial fibrillation (POAF), and transfusion. A restricted cubic spline (RCS) plot was used to characterize the continuous relationship of operative duration with the risk of APOs and early discharge. Results: The risks of the aforementioned APOs increased with each additional hour after the first hour. A J-shaped association with APOs was observed, with a higher risk in those with prolonged operative duration compared with those with shorter values. However, the probability of early discharge decreased from 0.465 to 0.350, 0.217, and 0.227 for each additional hour of operative duration compared with counterparts (<60 min), showing an inverse J-shaped association. The 90 min procedure appears to be a tipping point for a sharp increase in APOs and a significant reduction in early discharge. Conclusions: Our findings have important and meaningful implications for risk predictions and clinical interventions, and early rehabilitation, for APOs.

Abstract
BACKGROUND Longer bariatric, colorectal, plastic, spine, and urologic operations increase complications and lengths of stay. We aimed to determine whether this is a risk factor for lung lobectomy morbidity. METHODS The Society of Thoracic Surgeons General Thoracic Surgery Database was queried for early-stage non-small cell lung cancer lobectomy with surgical duration treated as a continuous variable. Univariate and multivariate analyses compared patient and clinical characteristics with perioperative outcomes and procedure durations. Robotic cases were combined with thoracoscopic cases for duration analyses into a minimally invasive group. All analyses were conducted in SAS v9.4 (SAS Institute, Cary, NC) at a significance level of .05. RESULTS In 17,852 patients mean duration of thoracotomy, thoracoscopy, and robotic lobectomies were 178 ± 84, 185 ± 73, and 214 ± 82 minutes, respectively (P < .001). The most common complications were prolonged air leak (12.3%), atrial fibrillation (12%), pneumonia (4.4%), and atelectasis requiring bronchoscopy (4.1%). Procedure duration was associated with increased odds of intraoperative packed red blood cell transfusion (P < .001) and length of stay > 5 days (P < .001) for both thoracotomy and minimally invasive lobectomy. Increased odds of pneumonia (P < .001), atelectasis (P < .001), and unexpected intensive care unit admission (P = .006) for thoracotomy lobectomy were associated with longer procedure duration. Increased lobectomy duration was not associated with readmission (P = .549) or 30-day mortality (P = .208). CONCLUSIONS Longer early-stage lung cancer lobectomy durations are associated with postoperative morbidity and increased length of stay. Although the effects of protracted operation times on long-term survival are unknown, short-term mortality differences were not detected. Measures that decrease operative durations without sacrificing safety and oncologic outcome should be undertaken by surgeons and hospital systems.

Abstract
Background The study carries the aim to compare the clinical efficacy and economic outcomes of using barbed suture closure versus conventional closure for wounds after posterior long-segment lumbar surgery. Methods One hundred and eighty-one patients undertaking posterior long-segment lumbar surgery participated in the prospective randomized controlled trial study to receive either barbed suture wound closure (n = 91) or conventional suture closure (n = 90). Outcome measures included operating room time (ORT), wound closure time, length of incision, length of hospital stay (LOS), 90-day readmission rates, wound complications of dehiscence and infection, and costs. Results Barbed suture group was related with significantly lower ORT (P = 0.036), wound closure time (P < 0.001) and average wound closure time (P < 0.001), and significantly lower wound complication rates (dehiscence and infection) (P = 0.031). No significant differences were found when compared with conventional suture group in terms of length of incision (P = 0.086), length of hospital stay (P = 0.174), readmission rates up to 90 days after the surgical procedure (P = 0.232) and costs (P = 0.205). Conclusion The study suggested the knotless barbed suture technique outperformed the conventional suture in shortening operating room time, wound closure time and average wound closure time, and reducing wound complication rates.

Standardized reporting of adverse events and functional status from the first 5 years of awake surgery for gliomas: a population-based single-institution consecutive series. Acta Neurochir (Wien) 2022; 164:1995-2008. [PMID: 35420374 DOI: 10.1007/s00701-022-05191-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2021] [Accepted: 03/16/2022] [Indexed: 11/29/2022]
Abstract
OBJECTIVE To report our experience and investigate frequencies of adverse events and functional status from the first 5 years of performing awake surgery for gliomas in a single-center population-based setting. METHODS We conducted a review of all patients with a glioma treated with awake surgery during the first 5 years following introduction of awake surgery at our center (February 2015 to February 2020). We assessed functional and radiological outcome, with adverse events classified according to the Landriel-Ibanez classification for neurosurgical complications, while neurological deficits were further subdivided into transient vs permanent. We sought to analyze our initial results and learning curve, as well as compare our results with literature. RESULTS Forty-two patients were included. The median age was 38 years (range 18-66) and 13 (31%) were female. The indication for awake surgery was a presumed glioma in or near an eloquent area. The overall 30-day complication rate was 25 (59%), with 19 (45%) grade I complications, 3 (7%) grade II complications, and 3 (7%) grade III complications. Fifteen patients (36%) experienced transient neurological deficits, and 11 (26%) permanent neurological deficits. At 3-month follow-up, the Karnofsky Performance Score was 80 or higher for the entire cohort. The median extent of resection was 87%, with GTR achieved in 11 (26%). In search of potential learning curve difficulties, patients were divided into the 21 patients treated first (Early Group) versus the remaining 21 patients treated later (Late Group); no statistically significant difference in operating time, amount of tumor removed, or incidence of long-term postoperative neurological deficit was identified between groups. No awake surgery was aborted due to seizures. Comparison to the literature was limited by the diverse and unsystematic way in which previous studies have reported adverse events after awake craniotomy for gliomas. CONCLUSION We provide a standardized report of adverse events and functional status following awake surgery for glioma during a single-center 5-year learning period, with similar rates of severe adverse events and functional outcome compared to literature without concerns of substantial learning curve difficulties. However, this comparison was flawed by non-standardized reporting of complications, highlighting a demand for more standardized reporting of adverse events after awake craniotomies.

Abstract
BACKGROUND Postoperative cranial wound infections are a major cause of morbidity, mortality, and financial burden, especially in developing countries. METHODS We prospectively studied 86 patients in a randomized trial; 39 patients received one gram of topical vancomycin powder in the subgaleal space while 47 matched control patients did not. Both groups received identical intraoperative and post-operative care. The primary outcome variable was the postoperative wound infections rate factored by cohort. Secondary outcomes were the timing of infection and the rate of adverse events. RESULTS Adding topical vancomycin was associated with a significantly lower rate of infection than the standard of care alone (2.6% [1/39] vs. 14.9% [7/47], P =.004). No adverse reactions occurred. CONCLUSION Topical vancomycin is safe, and effective in the prevention of surgical site infections following craniotomy. These findings have broad consequences for neurosurgery practice, especially in developing countries with high incidence of head trauma.

Discriminating surgical bed cysts from bacterial brain abscesses after Carmustine wafer implantation in newly diagnosed IDH-wildtype glioblastomas. Neurosurg Rev 2021; 45:1501-1511. [PMID: 34651215 DOI: 10.1007/s10143-021-01670-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Revised: 09/16/2021] [Accepted: 10/04/2021] [Indexed: 10/20/2022]
Abstract
Carmustine wafers can be implanted in the surgical bed of high-grade gliomas, which can induce surgical bed cyst formation, leading to clinically relevant mass effect. An observational retrospective monocentric study was conducted including 122 consecutive adult patients with a newly diagnosed supratentorial glioblastoma who underwent a surgical resection with Carmustine wafer implantation as first line treatment (2005-2018). Twenty-two patients (18.0%) developed a postoperative contrast-enhancing cyst within the surgical bed: 16 surgical bed cysts and six bacterial abscesses. All patients with a surgical bed cyst were managed conservatively, all resolved on imaging follow-up, and no patient stopped the radiochemotherapy. Independent risk factors of formation of a postoperative surgical bed cyst were age ≥ 60 years (p = 0.019), number of Carmustine wafers implanted ≥ 8 (p = 0.040), and partial resection (p = 0.025). Compared to surgical bed cysts, the occurrence of a postoperative bacterial abscess requiring surgical management was associated more frequently with a shorter time to diagnosis from surgery (p = 0.009), new neurological deficit (p < 0.001), fever (p < 0.001), residual air in the cyst (p = 0.018), a cyst diameter greater than that of the initial tumor (p = 0.027), and increased mass effect and brain edema compared to early postoperative MRI (p = 0.024). Contrast enhancement (p = 0.473) and diffusion signal abnormalities (p = 0.471) did not differ between postoperative bacterial abscesses and surgical bed cysts. Clinical and imaging findings help discriminate between surgical bed cysts and bacterial abscesses following Carmustine wafer implantation. Surgical bed cysts can be managed conservatively. Individual risk factors will help tailor their steroid therapy and imaging follow-up.

Abstract
Objective While adjuvant treatment regimens have been modified for older patients with glioblastoma (GBM), surgical strategies have not been tailored. Methods Clinical data of 48 consecutive patients aged 70 years or older, who underwent surgical resection for GBM with intraoperative ultrasonography (IoUS) alone or combination with intraoperative MRI (IoMRI) at Yale New Haven Hospital were retrospectively reviewed. Variables were analyzed, and comparative analyses were performed. Results The addition of IoMRI was not superior to IoUS alone in terms of overall survival (OS) (P = 0.306), Karnofsky Performance Score (KPS) at postoperative 6 weeks (P = 0.704) or extent of resection (P = 0.263). Length of surgery (LOSx), however, was significantly longer (P = 0.0002) in the IoMRI group. LOSx (P = 0.015) and hospital stay (P = 0.025) were predictors of postoperative complications. Increased EOR (GTR or NTR) (P = 0.030), postoperative adjuvant treatment (P < 0.0001) and postoperative complications (P = 0.006) were predictive for OS. Patients with relatively lower preoperative KPS scores (<70) showed significant improvement at postoperative 6 weeks (P<0.0001). Patients with complications (P = 0.038) were more likely to have lower KPS at postoperative 6 weeks. Conclusions Aggressive management with surgical resection should be considered in older patients with GBM, even those with relatively poor KPS. The use of ioMRI in this population does not appear to confer any measurable benefit over ioUS in experienced hands, but prolongs the length of surgery significantly, which is a preventable prognostic factor for impeding care.

Abstract
Background Audits of antimicrobial prophylaxis is an essential strategy to identify practice gaps in antimicrobial prescribing in healthcare facilities. There is a lack of studies on the costs, quality, and antimicrobial use density of neurosurgical perioperative antimicrobial prophylaxis in China. Objectives Evaluate the appropriateness of perioperative antimicrobial prophylaxis in neurosurgeries and analyze the costs, quality, and antimicrobial use density of neurosurgical perioperative antimicrobial prophylaxis. Setting Beijing Tsinghua Changgung Hospital, a teaching hospital in Beijing. Methods This retrospective study was conducted among 262 neurosurgical patients without infections during 2017. The appropriateness of perioperative antimicrobial prophylaxis was determined based on relevant international and Chinese perioperative antimicrobial prophylaxis guidelines. Main outcome measures Discrepancy rates in perioperative antimicrobial prophylaxis, including indication, choice of antimicrobials, dose, route of administration, time of administration of the first dose, re-dosing, and duration, were analyzed. Results Discrepancies were observed between current practice and relevant guidelines. A total of 51 (32.1%) procedures failed to administer intraoperative re-dosing as needed, and the perioperative antimicrobial prophylaxis duration of 217 (82.8%) procedures was inappropriately prolonged. The choice of antimicrobial agents was optimal in 249 (95%) procedures, and the timing of perioperative antimicrobial prophylaxis was appropriate in all procedures. If perioperative antimicrobial prophylaxis was implemented according to guidelines, the defined daily dose per 100 procedures would decrease from 31.97 to 16.99, and the total cost would reduce from $2000 to $490. Conclusions Effective antimicrobial stewardship is urgently needed to promote the appropriateness of neurosurgical perioperative antimicrobial prophylaxis in China.

Abstract
BACKGROUND To determine the phenotype, molecular characterisation and risk factors of postoperative meningitis induced by Extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae (EPE) in China. METHODS We performed a multi-centre comparative cohort study of postoperative meningitis patients infected with Enterobacteriaceae in 4 neurosurgical centres in China from January 2014 to December 2019. Phenotype and molecular characteristics of the isolates were reviewed and tested, and independent risk factors of the EPE meningitis were evaluated by binary logistic regression. RESULTS In total, 220 Enterobacteriaceae include 78 EPE were available in this study. 85.6% (67/78) ESBL-related genes were tested, and blaSHV (14.9%) and blaSHV + blaTEM + blaCTX-M-9 (20.9%) were found to be the most frequent mono and combined ESBL-related genes harboured by Enterobacteriaceae. On binary logistic analysis, craniotomy (OR. 2.583, 95% C.I. 1.274-5.235, P = 0.008) and malignancy (OR. 2.406, 95% C.I. 1.299-4.456, P = 0.005) were the associated independent risk factors to meningitis induced by EPE. CONCLUSIONS To the best of our knowledge, this is the largest series focusing on risk factors of EPE meningitis which has been conducted in China. Craniotomy and malignancy were independent risk factors for EPE meningitis. The risk factors identified may be further utilized in clinical practice and research to avoid and reduce the mortality in future.

Abstract
Although imaging of gliomas has evolved tremendously over the last decades, published techniques and protocols are not always implemented into clinical practice. Furthermore, most of the published literature focuses on specific timepoints in glioma management. This article reviews the current literature on conventional and advanced imaging techniques and chronologically outlines their practical relevance for the clinical management of gliomas throughout the cycle of care. Relevant articles were located through the Pubmed/Medline database and included in this review. Interpretation of conventional and advanced imaging techniques is crucial along the entire process of glioma care, from diagnosis to follow-up. In addition to the described currently existing techniques, we expect deep learning or machine learning approaches to assist each step of glioma management through tumor segmentation, radiogenomics, prognostication, and characterization of pseudoprogression. Thorough knowledge of the specific performance, possibilities, and limitations of each imaging modality is key for their adequate use in glioma management.

Abstract
BACKGROUND The association of operative time and surgical site infection (SSI) in neurosurgery patients is unclear. We therefore, through a systematic review and meta-analysis, sought to clarify the association. METHODS We performed a systematic search of the PubMed and Embase databases, from January 1, 1966, to December 26, 2018, for published articles. We used random effects generalized least squares regression models to combine study-specific relative risks (RR) and 95% confidence intervals (CI), and performed a sensitivity analysis by excluding 1 study at a time to assess the stability of results and potential sources of heterogeneity. We used the Egger (from plotting to test) to assess publication bias. RESULTS A total of 5 articles, with 231,915 individuals and 6,726 SSI cases, were included. The summary RR for SSI after craniotomy were 1.67 (95% CI, 1.13-2.20), with high versus low operative time, and 1.34 (95% CI, 1.15-1.53), with each 1-hour increase in operative time. On sensitivity analysis, no individual study had an excessive influence on the pooled effect. We found no evidence of publication bias by the Egger test (P = .464) and Egger's plotting. CONCLUSIONS Prolonged operative time can increase the SSI risk for neurosurgery patients. Intensive interventions should be taken to decrease operative duration.

Abstract
Introduction Surgical site infections pose a significant problem in the treatment of neurosurgical procedures, regardless of the application of perioperative prophylaxis with systemic antibiotics. The infection rate in these procedures ranges from less than 1% to above 15%. Different antibiotics and administration regimes have been used in the perioperative prophylaxis so far, and there are numerous comparative studies regarding their efficiency, however, it is generally indicated that the choice thereof should be based on information and local specifics connected to the most probable bacterial causers, which would possibly contaminate the surgical site and cause infection, and moreover, the mandatory compliance with the principles of providing adequate concentration of the drug at the time of the anticipated contamination. Objective Comparing the protective effect of two perioperative prophylactic antibiotic regimes using cefuroxime (second generation cephalosporin) and ceftriaxone (third generation cephalosporin) in the prevention of postoperative surgical site infections after elective and urgent cranial and spinal neurosurgical procedures at the University Clinic for Neurosurgery in Skopje in the period of the first three months of 2016. Design of the study Prospective randomized comparative study. Outcome measures Establishing the clinical outcome represented as prevalence of superficial and deep incision and organ/space postoperative surgical site infections. Material and method We analyzed prospectively 40 patients who received parenteral antibiotic prophylaxis with two antibiotic regimes one hour before the routine neurosurgical cranial and spinal surgical procedures; the patients were randomized in two groups, according to the order of admission and participation in the study, alternately, non-selectively, those persons who fulfilled inclusion criteria were placed in one of the two programmed regimes with cefuroxime in the first, and cefotaxime in the second compared group. All relevant demographic and perioperative patient data were analyzed for both comparative groups, especially the factors known to cause disposition (predisposition) to infections. The prevalence of postoperative infections was evaluated as the primary outcome in both comparative groups, while the secondary outcome was the postoperative infection rate after cranial and spinal neurosurgical procedures at the Neurosurgical clinic in Skopje (having in consideration that so far no data have been published in this context), as well as the prevalence of the risk factors for occurrence of postoperative infections, pre-surgically in patients undergoing neurosurgical interventions locally in the Republic of Macedonia. Results A total of three cases of postoperative infections were registered, two of which classified as superficial incisional, while one case organ/space infection - meningitis (elective intervention) without etiological confirmation. Both comparative groups were statistically similar, without any statistically significant differences in the basic demographic and perioperative characteristics, especially in relation to the incidence of the factors, which, regardless of the antibiotic prophylaxis, show predisposition to postoperative infections. All three cases with infections were registered in the group of persons who received prophylaxis with ceftriaxone preoperatively, with isolated etiological S. aureus agent (elective intervention) in one of them, and methicillin resistant staphylococcus aureus (MRSA) in another (urgent intervention) with superficial incisional SSI. There was no case of SSI in the group of patients who received cefuroxime before surgery. Conclusion Administration of parenteral antibiotics before surgery reduces the incidence of postoperative infections after neurosurgical procedures, especially in cases with increased risk factors for SSI, such as ACA score of ≥ 2/3, the duration of the surgical intervention ≥ 4 hours, contaminated wound and comorbidities. Perioperative antibiotic prophylaxis should be directed to better coverage of the S.aureus arrays.

Diffusion-weighted magnetic resonance imaging for detection of postoperative intracranial pyogenic abscesses in neurosurgery. Acta Neurochir (Wien) 2019; 161:985-993.

Abstract
BACKGROUND Diffusion-weighted magnetic resonance imaging (MRI-DWI) is the modality of choice for detecting intracranial abscesses; however, it is unclear whether prior brain surgery has an influence on its diagnostic value. Thus, we assessed the robustness of MRI-DWI and determination of an ADC cutoff value for detecting intracranial abscesses in patients who underwent brain surgery. METHODS We retrospectively evaluated 19 patients prior to surgery for postoperative supratentorial parenchymal abscesses by means of MRI-DWI. Forty randomly selected patients with routine postoperative MRI-DWI were used for comparative analyses. Clinical and serum biomarkers (C-reactive protein, interleukin-6, white blood cell count) as well as from results of early postoperative imaging findings (computed tomography and/or MRI scan) were recorded. Additionally, ADC values, T1±gadolinium, and T2/fluid-attenuated inversion recovery sequences were investigated. RESULTS After initial surgery, early postoperative control imaging showed evidence of hemorrhage and/or hemostatic agents within the resection cavity in 10/19 patients of the abscess group and in 16/40 patients of the control group. No postoperative ischemia was detected. Neither hemostatic agents nor blood affected the mean ADC values in both the reference group (blood 2.96 ± 0.22 × 10-3 mm2/s vs. no blood 2.95 ± 0.26 × 10-3 mm2/s, p = 0.076) and in the abscess group (blood 0.87 ± 0.07 × 10-3 mm2/s vs. no blood 0.76 ± 0.06 × 10-3 mm2/s, p = 0.128). The mean ADC value within the resection cavity was significantly lower in the abscess group (1.5 T 0.88 ± 0.41 vs. 2.88 ± 0.20 × 10-3 mm2/s, p < .01; 3.0 T 0.75 ± 0.24 vs. 3.02 ± 0.26 × 10-3 mm2/s, p < 0.01). The optimal ADC cut-off for the differentiation of an abscess from normal postoperative findings was found at 1.87 × 10-3 mm2/s (area-under-the-curve 1.0, sensitivity = 100%, specificity = 100%). Moreover, no differences between the abscess patients and the control group were seen with respect to the analyzed serum biomarkers. CONCLUSION MRI-DWI provides a robust tool to discriminate postoperative abscess formation from normal postoperative changes.

Abstract
OBJECTIVE Currently, the diagnosis of bone flap osteomyelitis (BFO) remains a challenge for medical imaging. The present study aimed to identify predictive scintigraphic patterns of BFO. METHODS This retrospective study reviewed planar bone scan of patients with suspected BFO between 2010, and 2016. A total of 15 patients were included. Final diagnosis of BFO was obtained by histological and bacteriological documentation. Eight scintigraphic signs potentially helpful were reviewed and correlated with the final diagnosis individually or in combination through Fischer exact test. RESULTS Eight patients out of 15 (53.3%) were diagnosed with BFO. Radionuclide uptake inside the bone flap during blood-pool phase was predictive for BFO (p = 0.007) with 75.0% sensitivity 100% specificity, and 86.7% accuracy. In combination, radionuclide uptake inside the bone flap or a spreading wavefront between blood-pool and delayed phases was associated with BFO (p = 0.007). It did not improve diagnostic performance. CONCLUSION Using well-defined and reproducible scintigraphic signs, bone scan is helpful for the diagnosis of BFO.

Abstract
BACKGROUND Previous studies have failed to demonstrate statistically significant differences in postsurgical outcomes between operative cases featuring resident participation compared to attending only; however, the effects of level of postgraduate year (PGY) training have not been explored. OBJECTIVE To correlate different PGYs in neurosurgery with 30-d postoperative outcomes. METHODS Using National Surgical Quality Improvement Program 2005-2014, adult neurosurgical cases were divided into subspecialties: spine, open-vascular, cranial, and functional in teaching institutions. Comparison groups: cases involving junior residents (PGY 1-PGY 3), mid-level residents (PGY 4 + PGY 5), and senior residents (PGY 6 + PGY 7). Primary outcome measures included any wound disruption (surgical site infections and/or wound dehiscence), Clavien-Dindo grade IV (life-threatening) complications, and death. RESULTS Compared to junior residents (n = 3729) and mid-level residents (n = 2779), senior residents (n = 3692) operated on patients with a greater comorbidity burden, as reflected by higher American Society of Anesthesiology classifications and decreased level of functional status. Cases with senior resident participation experienced the highest percentages of postoperative wound complications (P = .005), Clavien-Dindo grade IV complications (P = .001), and death (P = .035). However, following multivariable regression, level of residency training in neurosurgery did not predict any of the 3 primary outcome measures. Compared to spinal cases, cranial cases predicted a higher incidence of life-threatening complications (odds ratio 1.84, P < .001). CONCLUSION Cases in the senior resident cohort were more technically challenging and exhibited a higher comorbidity burden preoperatively; however, level of neurosurgical training did not predict any wound disruption, life-threatening complications, or death. Residents still provide safe and effective assistance to attending neurosurgeons.

Abstract
Surgery creates most hospital infections, injuries, accidents, invalidity and death in the global healthcare system. The number of surgically treated patients per year is high and increasing. Surgical site infection (SSI) is dependent on type of operation and may occur in 5–20% after surgery, triggers 7–11 extra postoperative days in hospitals and results in 2–11 times higher risk of death than comparable, noninfected patients. Up to 60% of SSI can be prevented. Prevention of postoperative wound infection is done by good general hygiene, operative sterility and effective barriers against transmission of infections, before, during and after surgery. A basic support by hospital leaders, knowledge and skill of the surgical teams, enough resources, excellent treatment of the complete patient admission and monitoring patients after discharge may lead to significant reduction of SSIs, lower death rates and a less expensive health system.

Abstract
Meticulous attention to wound closure in posterior lumbar spine surgery is an important principle in reducing surgical site infections. We detail standardized wound closure used for posterior lumbar spine surgery at a tertiary care referral center and illustrate this as a step-by-step cadaveric dissection. The lumbar spine of a cadaveric specimen (male, 73 years at death) was used for dissection. Standardizing wound closure in posterior lumbar spine surgery may help limit wound complications and infection. Some key points of our technique, as demonstrated on a cadaveric specimen, include separating fascial compartments, avoiding suture abscesses, and creating a tension-free wound.

Abstract
PURPOSE Surgical antibiotic prophylaxis (SAP) in pediatric neurosurgery has poorly been characterized until now. This review gives an overview on the current literature extracting recommendations and guidelines. METHODS The current literature on SAP with special forcus on pediatric neurosurgerical procedures was reviewed. Further, available recommendations in online databases were checked. Clean neurosurgical, shunt, and implant surgeries are considered separately. RESULTS To date, evidence-based data on SAP in pediatric neurosurgery remain sparse and there are no standardized approaches to an adequate use of antimicrobial agents for SSI prevention for this age group. CONCLUSION Due to statistical needs, multi-center surveillance studies are needed for implementing SAP recommendations in pediatric neurosurgery.

Predictors of Surgical Site Infection After Nonemergent Craniotomy: A Nationwide Readmission Database Analysis. World Neurosurg 2018; 120:e440-e452. [PMID: 30149164 DOI: 10.1016/j.wneu.2018.08.102] [Citation(s) in RCA: 40] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2018] [Revised: 08/12/2018] [Accepted: 08/13/2018] [Indexed: 10/28/2022]
Abstract
OBJECTIVE Surgical site infections (SSIs) carry significant patient morbidity and mortality and are a major source of readmissions after craniotomy. Because of their deleterious effects on health care outcomes and costs, identifying modifiable risk factors holds tremendous value. However, because SSIs after craniotomy are rare and most existing data comprise single-institution studies with small sample sizes, many are likely underpowered to discern for such factors. The objective of this study was to use a large hetereogenous patient sample to determine SSI incidence after nonemergent craniotomy and identify factors associated with readmission and subsequent need for wound washout. METHODS We used the 2010-2014 Nationwide Readmissions Database cohorts to discern for factors predictive of SSI and washout. RESULTS We identified 93,920 nonemergent craniotomies. There were 2079 cases of SSI (2.2%) and 835 reoperations for washout (0.89%) within 30 days of index admission and there were 2761 cases of SSI (3.6%) and 1220 reoperations for washout (1.58%) within 90 days. Several factors were predictive of SSI in multivariate analysis, including tumor operations, external ventricular drain (EVD), age, length of stay, diabetes, discharge to an intermediate-care facility, insurance type, and hospital bed size. Many of these factors were similarly implicated in reoperation for washout. CONCLUSIONS SSI incidence in neurosurgery is low and most readmissions occur within 30 days. Several factors predicted SSI after craniotomy, including operations for tumor, younger age, hospitalization length, diabetes, discharge to institutional care, larger hospital bed size, Medicaid insurance, and presence of an EVD. Diabetes and EVD placement may represent modifiable factors that could be explored in subsequent prospective studies for their associations with cranial SSIs.

Abstract
WHO surgical safety checklist has been proven to reduce postoperative infections in several studies. The aim of our study was to focus on surgical site infections (SSIs) after neurosurgical operations, and to determine whether the checklist implementation would have an impact on the reported SSIs. We used hospital-acquired infection (HAI) register to evaluate the effects of WHO surgical safety checklist in neurosurgery. The HAI register was searched for superficial and deep SSIs, deep organ SSIs, infections following orthopaedic implantation, and other surgical infections of 4678 neurosurgical patients operated on between 2007 and 2011. The data analysis consisted of 95 and 104 neurosurgical postoperative infections before and after the checklist implementation. Time from operation to infection was shorter before than after checklist implementation (p = 0.039), indicating a positive effect of the checklist use in the onset of early HAIs. The overall incidence of SSIs of all neurosurgical patients did not differ (4.1% and 4.5%, respectively) and no differences were noticed in the incidences of the subgroups of superficial SSIs, deep SSIs, and deep organ SSIs. The reduction in early postoperative infection rate along with checklist implementation, but not in the long run indicates the complexity of preventing HAIs in neurosurgical patients and need for a multistep infection control approach.

Abstract
BACKGROUND Neurosurgical surgical site infections (SSI) are life-threatening complications, requiring medical treatment and additional surgeries and remain a substantial cause of morbidity. In order to identify the incidence and the main risk factors for SSI, we developed the Prophylaxis with Antibiotic Protocol for Neurosurgical Site Infections Study (PASSIS), a prospective observational multicenter cohort study for examining a large number of neurosurgical procedures. METHODS The study PASSIS involved four Italian departments of neurosurgery applying the same antibiotic prophylaxis (ABP) protocol on 6359 consecutive neurosurgical procedures. In high-risk conditions (intra-operative contamination and/or postoperative cerebro-spinal fluid [CSF], and/or subcutaneous drainage and/or postoperative hyperpyrexia) and in presence of wound complication (CSF leak and/or CSF collection and/or wound diastasis), a prolongation protocol was prescribed. RESULTS The crude rate of SSI in the whole series was and 1.7% for patient and 1.5% for procedure. Patient related SSI risk factors: Younger patients (≤14 years) had a significantly higher SSI risk compared with older patients (RR: 2.17; 95% CI: 1.13-4.14). Patients underwent two surgeries were at increased SSI risk (RR: 3.80; 95% CI: 2.33-6.18), and the risk increased with the number of surgeries. Surgeries lasting longer than 3 hours (RR: 2.27; 95% CI: 1.15-4.50), undergoing two or more surgeries and the presence of prosthetic implants (RR: 2.40; 95% CI: 1.53-3.77) were procedure related SSI risk factors positively associated with SSI. In high-risk conditions and in wound complication as defined previously, ABP prolongation showed limited efficacy (RR:1.97; 95% CI: 1.21-3.22 and 9.31; 95% CI: 5.90-14.68 respectively). CONCLUSIONS The subjects submitted to complicated, repeated, long lasting craniotomies, especially if experiencing postoperative deterioration, display the higher risk of SSIs, as a final life-threatening complication. In order to reduce the SSI rate, further studies should address to design tailored prophylaxis protocols for each high risk situation as hereby defined; the wound complications deserve an increased microbiological surveillance, focusing the attention on the timing and source of infections.

Abstract
Background: The incidence of surgical site infection (SSI) across surgical procedures, specialties, and conditions is reported to vary from 0.1% to 50%. Operative duration is often cited as an independent and potentially modifiable risk factor for SSI. The objective of this systematic review was to provide an in-depth understanding of the relation between operating time and SSI. Patients and Methods: This review included 81 prospective and retrospective studies. Along with study design, likelihood of SSI, mean operative times, time thresholds, effect measures, confidence intervals, and p values were extracted. Three meta-analyses were conducted, whereby odds ratios were pooled by hourly operative time thresholds, increments of increasing operative time, and surgical specialty. Results: Pooled analyses demonstrated that the association between extended operative time and SSI typically remained statistically significant, with close to twice the likelihood of SSI observed across various time thresholds. The likelihood of SSI increased with increasing time increments; for example, a 13%, 17%, and 37% increased likelihood for every 15 min, 30 min, and 60 min of surgery, respectively. On average, across various procedures, the mean operative time was approximately 30 min longer in patients with SSIs compared with those patients without. Conclusions: Prolonged operative time can increase the risk of SSI. Given the importance of SSIs on patient outcomes and health care economics, hospitals should focus efforts to reduce operative time.

Abstract
BACKGROUND Postoperative infection after craniotomy carries an increased risk of morbidity and mortality. Identification and correction of the risk factors should be prioritized. The association of intraoperative hyperglycemia with postoperative infections in patients undergoing craniotomy is inadequately studied. METHODS A total of 224 patients were prospectively enrolled in 2 major medical centers to assess whether severe intraoperative hyperglycemia (SIH, blood glucose ≥180 mg/dL) is associated with an increased risk of postoperative infection in patients undergoing craniotomy. Arterial blood samples were drawn and analyzed immediately after anesthetic induction and again before tracheal extubation. The new onset of any type of infection within 7 days after craniotomy was determined. RESULTS The incidence of new postoperative composite infection was 10% (n = 22) within the first week after craniotomy. Weight, sex, American Society of Anesthesiologists score, preoperative and/or intraoperative steroid use, and diabetes mellitus were not associated with postoperative infection. SIH was independently associated with postoperative infection (odds ratio [95% confidence interval], 4.17 [1.50-11.56], P = .006) after fitting a multiple logistic regression model to adjust for emergency surgery, length of surgery, and age ≥65 years. CONCLUSIONS SIH is independently associated with postoperative new-onset composite infections in patients undergoing craniotomy. Whether prevention of SIH during craniotomy results in a reduced postoperative risk of infection is unknown and needs to be appraised by further study.

Abstract
Patients with malignant brain tumors are possibly at increased risk for surgical site infections (SSIs) considering the various medical situations associated with the disease. However, the actual rate of SSI after malignant brain tumor resection has not been well established, despite the potential impact of SSI on patient outcome. To investigate the incidence of SSI following malignant brain tumor surgery, we performed a retrospective study in 3 neurosurgical units. Subsequently, aiming at the reduction of incidence of SSI, we performed a prospective study using a care bundle technique in the same units. The SSI incidence in the retrospective (n = 161) and prospective studies (n = 68) were 4.3% and 4.4%, respectively, similar to the previously reports on general craniotomies. A care bundle does not appear to enhance prevention of SSI. However, future, large studies with a new care bundle should be planned based on a zero tolerance policy.

Abstract
OBJECTIVE Surgical site infections (SSIs) are costly to patients and the health care system. Pediatric neurosurgery SSI risk factors are not well defined. Intraoperative protocols have reduced, but have not eliminated, SSIs. The effect of preoperative intervention is unknown. Using quality improvement methods, a preoperative SSI prevention protocol for pediatric neurosurgical patients was implemented to assess its effect on SSI rate. METHODS Patients who underwent a scheduled neurosurgical procedure between January 2014 and December 2015 were included. Published evidence and provider consensus were used to guide preoperative protocol development. The Model for Improvement was used to test interventions. Intraoperative and postoperative management was not standardized or modified systematically. Staff, family, and overall adherence was measured as all-or-nothing. In addition, SSI rates among eligible procedures were measured before and after protocol implementation. RESULTS Within 4 months, overall protocol adherence increased from 51.3% to a sustained 85.7%. SSI rates decreased from 2.9 per 100 procedures preintervention to 0.62 infections postintervention (p = 0.003). An approximate 79% reduction in SSI risk was identified (risk ratio 0.21, 95% CI 0.08-0.56; p = 0.001). CONCLUSIONS Clinical staff and families successfully collaborated on a standardized preoperative protocol for pediatric neurosurgical patients. Standardization of the preoperative phase of care alone reduced SSI rates. Attention to the preoperative in addition to the intraoperative and postoperative phases of care may lead to further reduction in SSI rates.

Abstract
OBJECTIVE Surgical site infection (SSI) following CSF shunt operations has been well studied, yet risk factors for nonshunt pediatric neurosurgery are less well understood. The purpose of this study was to determine SSI rates and risk factors following nonshunt pediatric neurosurgery using a nationwide patient cohort and an institutional data set specifically for better understanding SSI. METHODS The authors reviewed the American College of Surgeons National Surgical Quality Improvement Program-Pediatric (ACS NSQIP-P) database for the years 2012-2014, including all neurosurgical procedures performed on pediatric patients except CSF shunts and hematoma evacuations. SSI included deep (intracranial abscesses, meningitis, osteomyelitis, and ventriculitis) and superficial wound infections. The authors performed univariate analyses of SSI association with procedure, demographic, comorbidity, operative, and hospital variables, with subsequent multivariate logistic regression analysis to determine independent risk factors for SSI within 30 days of the index procedure. A similar analysis was performed using a detailed institutional infection database from Children's of Alabama (COA). RESULTS A total of 9296 nonshunt procedures were identified in NSQIP-P with an overall 30-day SSI rate of 2.7%. The 30-day SSI rate in the COA institutional database was similar (3.3% of 1103 procedures, p = 0.325). Postoperative time to SSI in NSQIP-P and COA was 14.6 ± 6.8 days and 14.8 ± 7.3 days, respectively (mean ± SD). Myelomeningocele (4.3% in NSQIP-P, 6.3% in COA), spine (3.5%, 4.9%), and epilepsy (3.4%, 3.1%) procedure categories had the highest SSI rates by procedure category in both NSQIP-P and COA. Independent SSI risk factors in NSQIP-P included postoperative pneumonia (OR 4.761, 95% CI 1.269-17.857, p = 0.021), immune disease/immunosuppressant use (OR 3.671, 95% CI 1.371-9.827, p = 0.010), cerebral palsy (OR 2.835, 95% CI 1.463-5.494, p = 0.002), emergency operation (OR 1.843, 95% CI 1.011-3.360, p = 0.046), spine procedures (OR 1.673, 95% CI 1.036-2.702, p = 0.035), acquired CNS abnormality (OR 1.620, 95% CI 1.085-2.420, p = 0.018), and female sex (OR 1.475, 95% CI 1.062-2.049, p = 0.021). The only COA factor independently associated with SSI in the COA database included clean-contaminated wound classification (OR 3.887, 95% CI 1.354-11.153, p = 0.012), with public insurance (OR 1.966, 95% CI 0.957-4.041, p = 0.066) and spine procedures (OR 1.982, 95% CI 0.955-4.114, p = 0.066) approaching significance. Both NSQIP-P and COA multivariate model C-statistics were > 0.7. CONCLUSIONS The NSQIP-P SSI rates, but not risk factors, were similar to data from a single center.

Abstract
OBJECTIVES To determine the rate of surgical-site infections (SSI) in neurosurgical procedures involving a shared-resource intraoperative magnetic resonance imaging (ioMRI) scanner at a single institution derived from a prospective clinical quality management database. METHODS All consecutive neurosurgical procedures that were performed with a high-field, 2-room ioMRI between April 2013 and June 2016 were included (N = 195; 109 craniotomies and 86 endoscopic transsphenoidal procedures). The incidence of SSIs within 3 months after surgery was assessed for both operative groups (craniotomies vs. transsphenoidal approach). RESULTS Of the 109 craniotomies, 6 patients developed an SSI (5.5%, 95% confidence interval [CI] 1.2-9.8%), including 1 superficial SSI, 2 cases of bone flap osteitis, 1 intracranial abscess, and 2 cases of meningitis/ventriculitis. Wound revision surgery due to infection was necessary in 4 patients (4%). Of the 86 transsphenoidal skull base surgeries, 6 patients (7.0%, 95% CI 1.5-12.4%) developed an infection, including 2 non-central nervous system intranasal SSIs (3%) and 4 cases of meningitis (5%). Logistic regression analysis revealed that the likelihood of infection significantly decreased with the number of operations in the new operational setting (odds ratio 0.982, 95% CI 0.969-0.995, P = 0.008). CONCLUSIONS The use of a shared-resource ioMRI in neurosurgery did not demonstrate increased rates of infection compared with the current available literature. The likelihood of infection decreased with the accumulating number of operations, underlining the importance of surgical staff training after the introduction of a shared-resource ioMRI.

Abstract
Surgical transection of sensory nerves in the treatment of intractable neuropathic pain is a commonly performed procedure. At times these cases can be particularly challenging when encountering obese patients, when targeting deeper nerves or those with a variable branching pattern, or in the case of repeat operations. In this case series, the authors describe their experience with ultrasound-guided surgical instrument placement during transection of a saphenous nerve in the region of prior vascular surgery in 1 patient and in the lateral femoral cutaneous nerve in 2 obese patients. The authors also describe this novel technique and provide pilot data that suggests ultrasound-assisted surgery may allow for complex cases to be completed in an expedited fashion through smaller incisions.

Cerebral abscess after neuro-vascular embolization: Own experience and review of the literature. Acta Neurochir (Wien) 2017; 159:583-591. [PMID: 28116528 DOI: 10.1007/s00701-016-3069-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2016] [Accepted: 12/22/2016] [Indexed: 10/20/2022]
Abstract
BACKGROUND Cerebral abscesses are a rare complication after therapeutic neuro-endovascular procedures. METHOD The aim of this article is to report a case of cerebral abscess after the endovascular embolization of a cerebral aneurysm and to discuss and review all the cases of cerebral abscess secondary to neurovascular embolization described in the literature up to now. RESULTS A 40-year-old female patient was treated using an endovascular embolization for a ruptured aneurysm of the basilar artery tip. After 2 months she presented with a cerebellar abscess. Antibiotic therapy was started, and a surgical drainage of the collection was performed, with a favorable postoperative outcome. Twelve other cases were reported in the literature, in five cases secondary to the treatment of a cerebral aneurysm, in six cases secondary to a cerebral arterio-venous malformation (AVM) and in one case secondary to a dural arterio-venous fistula (DAVF). The pathophysiology and risk factors of cerebral abscess formation are discussed in detail. CONCLUSIONS The risk of cerebral abscesses after neuro-endovascular embolization is not negligible, and a growing number of patients affected by this complication may be expected in the near future because of the spreading of neuro-endovascular techniques. The role of prophylactic antibiotic therapy in specific subgroups of patients is still debated.

Clinical practice audit concerning antimicrobial prophylaxis in paediatric neurosurgery: results from a German paediatric oncology unit. Childs Nerv Syst 2017; 33:159-169. [PMID: 27822762 DOI: 10.1007/s00381-016-3279-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2016] [Accepted: 10/14/2016] [Indexed: 10/20/2022]
Abstract
BACKGROUND Perioperative antimicrobial prophylaxis (PAP) has been identified as an important target for internal audits, concerning the judicious use of antibiotics. Paediatric oncology patients with brain tumours face an increased risk of surgical site infection (SSI) after neurosurgery and receive routine PAP in this setting. PATIENTS AND METHODS All patients younger than 18 years admitted to the paediatric oncology centre (POC) with a neurosurgical intervention. Systematic audit of routine clinical data is divided in two groups: retrospective (Jan 01, 2012-March 31, 2014) and prospective (April 01, 2014-March 31, 2015) referring to an internal PAP guideline, invented in Jan. 2014). Surveillance of SSI up to 30 days after the operation with standard criteria (Centres for Disease Control and Prevention, USA). RESULTS In total, 53 neurosurgical operations were analysed in 33 paediatric oncology patients. Twelve patients received more than one operation. The detailed analysis of PAP revealed prophylactic cefuroxim doses about 30 mg/kg instead of 50 mg/kg and no repeated dosing in operations lasting longer than 4 h. In addition, Cefotaxim, which is not indicated as PAP in neurosurgery, was used instead of Cefuroxim (or Ampicillin-Sulbactam) in 23 % of all cases in the retrospective and 18 % of all cases in the prospective audit. PAP for more than 3 doses (>24 h) was administered in 66 % in the retrospective group and in 60 % in the prospective group (p = n.s.). In both groups, no SSI was detected. DISCUSSION This first comprehensive audit of PAP in paediatric oncology patients undergoing neurosurgery outlines significant opportunities to improve clinical practice in terms of correct dosing, the correct choice of the antibiotic, a correct timing schedule and a shorter duration of PAP. In addition, our results illustrate in detail the challenges in clinical practice when an evidence-based approach to improve a standard workflow has to be implemented.
