Abstract
Introduction We aimed to implement the enhanced recovery after surgery (ERAS) protocol for pediatric neuromuscular scoliosis (NMS) surgery and to examine the effectiveness of this program in this study. Methods Subjects were children with NMS who underwent scoliosis surgery at our department by a surgeon using a single posterior approach. A series of 27 cases before the introduction of ERAS and 27 cases during program stabilization were included in the study. Patient backgrounds did not show significant differences before and after introducing ERAS. Perioperative data, complications, length of hospital stay (LOS), and readmission within 90 days were investigated and statistically analyzed. Results When the pre- and post-ERAS induction groups were compared, no significant differences in anesthesia induction time (p=0.979), pelvic fixation (p=0.586), fusion levels (p=0.479), intraoperative hypothermia duration (p=0.154), end-of-surgery body temperature (p=0.197), operative time (p=0.18), postoperative main Cobb angle (p=0.959), main Cobb angle correction rate (p=0.91), postoperative spino-pelvic obliquity (SPO) (p=0.849), and SPO correction rate (p=0.267) were observed. However, significant differences in using V-flap technique (p=0.041), intraoperative blood loss (p=0.001), and LOS (p=0.001) were observed. Intraoperative blood loss was weakly correlated with LOS (p=0.432 and 0.001). No statistically significant difference existed between the V-flap method and LOS (p=0.265). Multiple regression analysis using LOS as the objective variable and ERAS protocols and intraoperative blood loss as explanatory variables revealed that the effect of ERAS on LOS was greater than that of intraoperative blood loss. No statistically significant differences in the readmission rates within 90 days were found. Conclusions After the introduction of ERAS, LOS decreased without an increase in complications or readmissions within 90 days.

The effect of antibiotic-impregnated calcium sulfate beads and Medical Optimization Clinic attendance on the acute surgical site infection rate in high-risk pediatric neuromuscular and syndromic scoliosis patients. Spine Deform 2024; 12:1089-1098. [PMID: 38457028 DOI: 10.1007/s43390-024-00837-8] [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: 10/10/2023] [Accepted: 02/01/2024] [Indexed: 03/09/2024]
Abstract
BACKGROUND Neuromuscular and syndromic (NMS) scoliosis patients are at higher risk of acute surgical site infections (SSIs). Despite following POSNA's endorsed consensus-based guidelines for SSI prevention, our institutional rates of acute SSI have varied dramatically. This variability drove simultaneous strategies to lower SSI rates: the creation of a preoperative Medical Optimization Clinic (MOC) and use of antibiotic-impregnated (Abx-I) calcium sulfate beads. METHODS Patients undergoing index PSF at a single institution between 2016 and 2022 were retrospectively reviewed. Patients with ≥ 2 risk factors were included: (1) BMI < 18.5 or > 25; (2) incontinence; (3) instrumentation to pelvis; (4) non-verbal; (5) GMFCS IV/V. SSI was defined as deep infection within 90 days. We compared patients who attended MOC and received Abx-I (MOC + Abx-I) to those receiving neither intervention (control) nor a single intervention. RESULTS 282 patients were included. The overall infection rate was 4.26%. Higher GMFCS (p = 0.0147), non-verbal status (p = 0.0048), and longer fusions (p = 0.0298) were independently associated with infection rate. Despite the MOC + Abx-I group having larger Cobb angles (88° ± 26°), higher GMFCS levels (4.5 ± 0.9), ASA class (3 ± 0.4), and more frequent instrumentation to the pelvis (85%), they had the lowest infection rate (2.13%) when compared to the control (4.2%) or single intervention groups (5.7%, 4.6%) (p = 0.9). CONCLUSION The study examined the modern infection rate of NMS patients following the implementation of two interventions: MOC and Abx-I. Despite having higher risk factors (curves (88°), GMFCS level (4.5), ASA class (3), higher % instrumentation to the pelvis (85%)), the patients treated with both interventions demonstrated the lowest infection rate (2.13%).

Perioperative Health Interventions in Children With Chronic Neuromuscular Conditions Undergoing Major Musculoskeletal Surgery: A Scoping Review. Hosp Pediatr 2024; 14:e281-e291. [PMID: 38726564 DOI: 10.1542/hpeds.2021-006187] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Revised: 02/06/2024] [Accepted: 02/09/2024] [Indexed: 06/02/2024]
Abstract
BACKGROUND AND OBJECTIVES Children with chronic neuromuscular conditions (CCNMC) have many coexisting conditions and often require musculoskeletal surgery for progressive neuromuscular scoliosis or hip dysplasia. Adequate perioperative optimization may decrease adverse perioperative outcomes. The purpose of this scoping review was to allow us to assess associations of perioperative health interventions (POHI) with perioperative outcomes in CCNMC. METHODS Eligible articles included those published from January 1, 2000 through March 1, 2022 in which the authors evaluated the impact of POHI on perioperative outcomes in CCNMC undergoing major musculoskeletal surgery. Multiple databases, including PubMed, Embase, Cumulative Index of Nursing and Allied Health Literature, Web of Science, the Cochrane Library, Google Scholar, and ClinicalTrials.gov, were searched by using controlled vocabulary terms and relevant natural language keywords. Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines were used to perform the review. A risk of bias assessment for included studies was performed by using the Risk of Bias in Non-randomized Studies of Interventions tool. RESULTS A total of 7013 unique articles were initially identified, of which 6286 (89.6%) were excluded after abstract review. The remaining 727 articles' full texts were then reviewed for eligibility, resulting in the exclusion of 709 (97.5%) articles. Ultimately, 18 articles were retained for final analysis. The authors of these studies reported various impacts of POHI on perioperative outcomes, including postoperative complications, hospital length of stay, and hospitalization costs. Because of the heterogeneity of interventions and outcome measures, meta-analyses with pooled data were not feasible. CONCLUSIONS The findings reveal various impacts of POHI in CCNMC undergoing major musculoskeletal surgery. Multicenter prospective studies are needed to better address the overall impact of specific interventions on perioperative outcomes in CCNMC.

Effectiveness of Gentamicin Wound Irrigation in Preventing Surgical Site Infection During Lumbar Spine Surgery: A Retrospective Study at a Rural Teaching Hospital in India. Cureus 2023; 15:e46094. [PMID: 37900478 PMCID: PMC10611903 DOI: 10.7759/cureus.46094] [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] [Accepted: 09/27/2023] [Indexed: 10/31/2023] Open
Abstract
BACKGROUND Surgical site infections (SSIs) are an opposing result of surgery and account for the majority of healthcare-related infections worldwide. It is one of the most common complications associated with open-spine surgery and is associated with high rates of mortality and high demand for healthcare resources. Surgical site infections are the result of a variety of reasons, which is why a range of prevention strategies have been proposed. Intraoperative wound irrigation (IOWI) is a simple procedure that involves moving a solution through an open wound to help hydrate the tissue. It is a type of prophylactic wound irrigation. It removes and dilutes bodily fluids, bacteria, and cellular debris. It may also act as a bactericidal agent when used with antibiotics and antiseptics. AIMS AND OBJECTIVES To evaluate the incidence of SSI in lumbar spine surgeries by comparing IOWI with normal saline containing gentamicin (NS-G) and normal saline (NS) alone. MATERIALS AND METHOD A hospital-based retrospective study was conducted among 40 patients who underwent elective lumbar spine surgery at the Department of Orthopaedics, RL Jalappa Hospital Centre, Kolar, Karnataka, India. RESULT Out of the total participants enrolled, 60% were males and 40% were females. There was no statistically significant difference found between mean age, mean BMI, mean hemoglobin level, mean WBC counts, and mean fasting blood sugar (FBS) levels among both groups. The overall prevalence of SSI among patients was 25%. In Group A (NS-G), the prevalence of SSI was 15%, and in Group B (NS), it was 35%. In total, 17.5% of study participants had superficial SSI, while 7.5% had deep SSI. CONCLUSION Gentamicin, an aminoglycoside antibiotic, is bactericidal and efficient against gram-positive organisms like Staphylococcus, the most frequent pathogen causing SSI in spine surgery. During lumbar spine surgery, IOWI with saline and gentamicin before closure is more effective in preventing SSI than simple saline irrigation.

Abstract
BACKGROUND Best Practice Guidelines (BPGs) regarding antibiotic prophylaxis in early-onset scoliosis (EOS) patients were published in September 2019. Recommendations included using intravenous cefazolin and topical vancomycin for all index procedures, plus gram-negative coverage for neuromuscular patients. Guideline adherence is unknown. This study aimed to characterize antibiotic prophylaxis at the time of index growth-friendly procedures and assess changes in practice patterns over time. MATERIALS AND METHODS This retrospective review of data collected through a multicenter study group included EOS patients undergoing index growth-friendly procedures between January 2018 and March 2021, excluding revisions, lengthenings, and tetherings. Demographics, clinical measurements, intraoperative antibiotics, and 90-day complications were recorded. Descriptive and univariate statistics were utilized. Antibiotic prophylaxis from April 2018 through September 2019 and October 2019 through March 2021 were compared with evaluate change after BPG publication. RESULTS A total of 562 patients undergoing growth-friendly procedures were included. The most common scoliosis types included neuromuscular (167, 29.7%), syndromic (134, 23.8%), and congenital (97, 17.3%). Most index procedures involved magnetically controlled growing rods (417, 74%) followed by vertical expandable prosthetic titanium rib or traditional growing rods (105, 19%). Most patients received cefazolin alone at index procedure (310, 55.2%) or cefazolin with an aminoglycoside (113, 20.1%). Topical antibiotics were used in 327 patients (58.2%), with most receiving vancomycin powder. There was increased use of cefazolin with an aminoglycoside after BPG publication (16% vs. 25%) ( P =0.01). Surgical site infections occurred in 12 patients (2.1%) within 90 days of index procedure, 10 pre-BPGs (3%), and 2 post-BPGs (0.9%), with no significant difference in surgical site infection rate by type of antibiotic administered ( P >0.05). CONCLUSIONS Historical variability exists regarding antibiotic prophylaxis during index growth-friendly procedures for EOS. There continues to be variability following BPG publication; however, this study found a significant increase in antibiotic prophylaxis against gram-negative bacteria after BPG publication. Overall, greater emphasis is needed to decrease variability in practice, improve compliance with consensus guidelines, and evaluate BPG efficacy. LEVEL OF EVIDENCE Level III-retrospective.

Perioperative prophylaxis for surgical site infections in pediatric spinal surgery: a systematic review and network meta-analysis. J Neurosurg Pediatr 2023; 31:43-51. [PMID: 36308474 DOI: 10.3171/2022.9.peds22316] [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: 07/27/2022] [Accepted: 09/09/2022] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Postoperative infections in pediatric spinal surgery commonly occur and necessitate reoperation(s). However, pediatric-specific infection prophylaxis guidelines are not available. This network meta-analysis compares perioperative prophylaxis methods including Betadine irrigation, saline irrigation, intrawound vancomycin powder, combination therapy (Betadine, vancomycin, gentamicin, and cefuroxime), Betadine irrigation plus vancomycin powder, and no intervention to determine the most efficacious prevention method. METHODS A systematic review was performed by searching the PubMed, EBSCO, Scopus, and Web of Science databases for peer-reviewed articles published prior to February 2022 comparing two or more infection prophylaxis methods in patients younger than 22 years of age. Data were extracted for treatment modalities, patient demographics, and patient outcomes such as total number of infections, surgical site infections, deep infections, intraoperative blood loss, operative time, follow-up time, and postoperative complications. Quality and risk of bias was assessed using National Institutes of Health tools. A network meta-analysis was performed with reduction of infections as the primary outcome. RESULTS Overall, 10 studies consisting of 5164 procedures were included. There was no significant difference between prophylactic treatment options in reduction of infection. However, three treatment options showed significant reduction in total infection compared with no prophylactic treatment: Betadine plus vancomycin (OR 0.22, 95% CI 0.09-0.54), vancomycin (OR 3.26, 95% CI 1.96-5.44), and a combination therapy (Betadine, vancomycin, gentamicin, and cefuroxime) (OR 0.24, 95% CI 0.07-0.75). P-Score hierarchical ranking estimated Betadine plus vancomycin to be the superior treatment to prevent total infections, deep infections, and surgical site infections (P-score 0.7876, 0.7175, and 0.7291, respectively). No prophylaxis treatment-related complications were reported. CONCLUSIONS The results of this network meta-analysis show the strongest support for Betadine plus vancomycin as a method to reduce infections following pediatric spinal surgery. There was heterogeneity among studies and inconsistent outcome reporting; however, three effective treatment options are identified.

Irrigation techniques used in spine surgery for surgical site infection prophylaxis: a systematic review and meta-analysis. BMC Musculoskelet Disord 2022; 23:813. [PMID: 36008858 PMCID: PMC9414142 DOI: 10.1186/s12891-022-05763-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2022] [Accepted: 08/16/2022] [Indexed: 11/10/2022] Open
Abstract
Background The greater likelihood of morbidity, mortality, length of hospital stays and poorer long-term outcomes as a result of surgical site infections secondary to spinal surgery makes prophylactic measures an imperative focus. Therefore, the aim of this review was to evaluate the available research related to the efficacy of different intraoperative irrigation techniques used in spinal surgery for surgical site infection (SSI) prophylaxis. Methods We performed a comprehensive search using Ovid Medline, EMBASE, Web of Science and the Cochrane library pertaining to this topic. Our meta-analysis was conducted according to PRISMA guidelines. The inclusion criteria consist of spine surgeries with intraoperative use of any wound irrigation technique, comparison groups with a different intraoperative irrigation technique or no irrigation, SSI identified with bacterial cultures or clinically in the postoperative period, reported SSI rates. Data extracted from eligible studies included, but was not limited to, SSI rates, irrigation technique and control technique. Exclusion criteria consist of articles with no human subjects, reviews, meta-analyses and case control studies and no details about SSI identification or rates. Pooled risk ratios were calculated. A meta-analysis was performed with a forest plot to determine risk estimates’ heterogeneity with I2 index, Q-statistic, and p value under a random-effects model. Funnel plot was used to assess publication bias. All databases were last checked on January, 2022. PROBAST tool was used to assess both risk of bias and applicability concerns. Results After reviewing 1494 titles and abstracts, 18 articles met inclusion criteria. They included three prospective randomized-controlled trials, 13 retrospective cohort studies, two prospective cohort studies. There were 54 (1.8%) cases of SSIs in the povidone-iodine irrigation group (N = 2944) compared to 159 (4.6%) in the control group (N = 3408). Using intraoperative povidone-iodine wound irrigation produced an absolute risk reduction of 2.8%. Overall risk ratio was 0.32 (95% CI 0.20–0.53, p < 0.00001). In a global analysis, study heterogeneity and synthesizing mostly retrospective data were primary limitations. Conclusion The most evidence exists for povidone-iodine and has Level 2 evidence supporting SSI reduction during spinal surgery. Other antiseptic solutions such as dilute chlorhexidine lack published evidence in this patient population which limits the ability to draw conclusions related to its use in spinal surgery. Level of Evidence II – Systematic Review with Meta-Analysis.

Abstract
A surgical site infection (SSI) is an infection that occurs in the incision created by an invasive surgical procedure. Although most infections are treatable with antibiotics, SSIs remain a significant cause of morbidity and mortality after surgery and have a significant economic impact on health systems. Preventive measures are essential to decrease the incidence of SSIs and antibiotic abuse, but data in the literature regarding risk factors for SSIs in the pediatric age group are scarce, and current guidelines for the prevention of the risk of developing SSIs are mainly focused on the adult population. This document describes the current knowledge on risk factors for SSIs in neonates and children undergoing surgery and has the purpose of providing guidance to health care professionals for the prevention of SSIs in this population. Our aim is to consider the possible non-pharmacological measures that can be adopted to prevent SSIs. To our knowledge, this is the first study to provide recommendations based on a careful review of the available scientific evidence for the non-pharmacological prevention of SSIs in neonates and children. The specific scenarios developed are intended to guide the healthcare professional in practice to ensure standardized management of the neonatal and pediatric patients, decrease the incidence of SSIs and reduce antibiotic abuse.

The Hydrocephalus Clinical Research Network quality improvement initiative: the role of antibiotic-impregnated catheters and vancomycin wound irrigation. J Neurosurg Pediatr 2022:1-8. [PMID: 35303708 DOI: 10.3171/2022.2.peds2214] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2022] [Accepted: 02/02/2022] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Two previous Hydrocephalus Clinical Research Network (HCRN) studies have demonstrated that compliance with a standardized CSF shunt infection protocol reduces shunt infections. In this third iteration, a simplified protocol consisting of 5 steps was implemented. This analysis provides an updated evaluation of protocol compliance and evaluates modifiable shunt infection risk factors. METHODS The new simplified protocol was implemented at HCRN centers on November 1, 2016, for all shunt procedures, excluding external ventricular drains, ventricular reservoirs, and subgaleal shunts. Procedures performed through December 31, 2019, were included (38 months). Compliance with the protocol, use of antibiotic-impregnated catheters (AICs), and other variables of interest were collected at the index operation. Outcome events for a minimum of 6 months postoperatively were recorded. The definition of infection was unchanged from the authors' previous report. RESULTS A total of 4913 procedures were performed at 13 HCRN centers. The overall infection rate was 5.1%. Surgeons were compliant with all 5 steps of the protocol in 79.4% of procedures. The infection rate for the protocol alone was 8.1% and dropped to 4.9% when AICs were added. Multivariate analysis identified having ≥ 2 complex chronic conditions (odds ratio [OR] 1.76, 95% confidence interval [CI] 1.26-2.44, p = 0.01) and a history of prior shunt surgery within 12 weeks (OR 1.84, 95% CI 1.37-2.47, p < 0.01) as independent risk factors for shunt infection. The use of AICs (OR 0.70, 95% CI 0.50-0.97, p = 0.05) and vancomycin irrigation (OR 0.36, 95% CI 0.21-0.62, p < 0.01) were identified as independent factors protective against shunt infection. CONCLUSIONS The authors report the third iteration of their quality improvement protocol to reduce the risk of shunt infection. Compliance with the protocol was high. These updated data suggest that the incorporation of AICs is an important, modifiable infection prevention measure. Vancomycin irrigation was also identified as a protective factor but requires further study to better understand its role in preventing shunt infection.

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.

Perioperative outcome and complications following single-staged Posterior Spinal Fusion (PSF) using pedicle screw instrumentation in Adolescent Idiopathic Scoliosis (AIS): a review of 1057 cases from a single centre. BMC Musculoskelet Disord 2021; 22:413. [PMID: 33947368 PMCID: PMC8097957 DOI: 10.1186/s12891-021-04225-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Accepted: 04/01/2021] [Indexed: 11/23/2022] Open
Abstract
Background There has been a growing interest in using all pedicle screw construct in posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS) surgery in recent years. However, studies focusing on perioperative outcome and complications utilizing only pedicle screw system in AIS population are lacking. This study aims to evaluate perioperative outcomes and to determine the prevalence of major and minor complications following single-staged PSF for AIS. Methods In this retrospective study of prospectively collected data, 1057 AIS patients operated between 2012 and 2019 were included. Main outcome measures were operative time, intraoperative blood loss, allogeneic blood transfusion rate, length of hospital stay after surgery, complication rate, and mean drop of haemoglobin (Hb) level. We documented the number of fusion levels, screw density, and postoperative radiographic parameters. Results There were 917 females and 140 males. Majority were Lenke 1 curve type (46.9%). Mean age was 15.6 ± 3.7 years, with mean BMI of 18.6 ± 3.2 kg/m2. Mean operative time was 146.8 ± 49.4 min. Average intraoperative blood loss was 952.9 ± 530.4 ml with allogeneic blood transfusion rate of 5%. Mean screw density was 1.27 ± 0.21 screws per fusion level. Average hospital stay after surgery was 3.5 ± 0.9 days. Twenty-four complications were documented: twelve superficial infections (1.14%), five transient neurological deficits (0.47%), two deep infections (0.19%), two superior mesenteric artery syndrome, and one case each (0.09%) for massive intraoperative blood loss, intraoperative seizure, and lung atelectasis. Conclusion AIS patients treated with single-staged PSF using pedicle screw construct had a 0.95% rate of major complications and 1.32% rate of minor complications. Rate of neurologic complication was 0.47% while non-neurologic postoperative complications was 1.80% with infection being the leading complication at 1.32%.
