Purpose: Children with neuromuscular scoliosis (NMS) undergoing posterior spinal fusion (PSF) have historically been managed post-operatively in the pediatric intensive care unit (PICU) due to institutional tendencies. This study sought to define risk factors for PICU admission when using an enhanced recovery after surgery (ERAS) pathway., Methods: A retrospective review of children with non-ambulatory (GMFCS 4 or 5) cerebral palsy undergoing PSF for NMS performed at two institutions by 5 surgeons. Both institutions have a pre-existing ERAS pathway for NMS patients consisting of post-surgical transfer to the hospital floor with early reinstitution of feeding and mobilization. PICU admission is used at the discretion of the surgeon and anesthesiologist rather than by institutional decree. Patient and surgical factors were assessed for risk factors of PICU admission., Results: A total of 103 children were included (84% GMFCS 5, mean 14.52 years (± 3.4 years)). Forty children (38.8%) required postoperative PICU admission. PICU admission was associated with seizure disorder (P = 0.09), pre-existing feeding tube (P = 0.003), tracheostomy (P = 0.03), and modified GMFCS-5 subclassification (P = 0.003). Independent predictors of PICU admission include pre-existing feeding (Odd's ratio = 2.9, P = 0.02) and length of surgery (Odd's ratio = 2.6, P < 0.001), with surgery lasting ≥ 5.0 h having an 82.5% sensitivity and 63.5% specificity (AUC 0.8, P < 0.001) for post-operative PICU admission., Conclusion: The majority of children with non-ambulatory cerebral palsy can be successfully managed on the hospital floor following PSF. The extent of central neuromotor impairment is significantly associated with PICU admission along with surgery lasting longer than 5 h., (© 2022.

Purpose: Intraoperative methadone has been shown to decrease opioid medication requirement following posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). No study to date has investigated the effect of methadone on opioid medication requirement when used in conjunction with an enhanced recovery after surgery (ERAS) protocol following PSF., Methods: A retrospective cohort study was performed at a single, tertiary care pediatric hospital. Patients with AIS undergoing PSF were consecutively given a single intra-operative methadone dose and matched 1:2 to a AIS control group without methadone. Patients were matched for age, curve magnitude, levels fused, blood loss, and operating time. All children followed a standard ERAS protocol with methadone being the only change in the post-operative regimen. In-hospital data for opioid and non-opioid medication use, surgical, and patient variables were recorded and compared between cohorts., Results: Twenty-six patients received methadone (average 15.1 ± 1.9 years) and were matched with 52 control patients without methadone (average 14.7 ± 2.2 years). There were no significant differences in total opioid usage at any time-interval prior to hospital discharge or in cumulative opioid usage. Additionally, patients had a similar VAS pain level at discharge (methadone: 4.0 ± 2.3 vs control: 3.8 ± 1.9; P = 0.572). Total opioid usage was correlated with LOS. There were no opioid-related medication complications in either cohort., Conclusion: There was no decrease of in-hospital opioid usage when methadone was used with an ERAS protocol. Total opioid usage is correlated with hospital LOS following PSF., (© 2021. This is a U.S. government work and not under copyright protection in the U.S.; foreign copyright protection may apply.)

Purpose: Enhanced Recovery after Surgery (ERAS) pathways have been shown to decrease length of stay (LOS) after posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). The aim of this study was to compare immediate post-operative outcomes following an ERAS pathway with a traditional pathway for AIS., Methods: A prospective dual-center study of patients treated using an ERAS pathway (203 patients) or a traditional discharge (TD) pathway (73 patients) was performed with focus on pain at discharge, quality of life at one month, and return to school/work., Results: LOS was 55% less in the ERAS group (4.8 days TD vs. 2.2 days ERAS, p < 0.001). Length of surgery (4.8 h TD vs. 2.8 h, p < 0.001) and EBL (500 cc vs. 240 cc, p < 0.001) were greater in the TD group, likely related to larger curve magnitudes ((62.0° TD vs. 54.0° ERAS, p < 0.001), a higher percentage of patients undergoing osteotomies (94% vs. 46%, p < 0.001) and more levels fused (11.4 ± 1.6 vs. 10.1 ± 2.6, p < 0.001) in the TD group. Regression analysis showed no difference in Visual Analog Score (VAS) score at discharge or quality of recovery using the QOR9 instrument between groups at follow up. There was no difference in return to school (p = 0.43) and parents' return to work (p = 0.61) between the groups., Conclusion: Patients managed with an ERAS pathway had similar pain scores at discharge than those managed with a TD pathway. Both groups showed evidence of rapid return to normalcy by the first follow up visit., (© 2021. Scoliosis Research Society.)

Background: Patients with neuromuscular scoliosis (NMS) who undergo posterior spinal fusion (PSF) often have long, protracted hospital stays because of numerous comorbidities. Coordinated perioperative pathways can reduce length of hospitalization (LOH) without increasing complications; however, a subset of patients may not be suited to rapid mobilization and early discharge., Methods: 197 patients with NMS underwent PSF at a single hospital by two surgeons with a post-operative care pathway emphasizing early mobilization, rapid transition to enteral feeds, and discharge prior to first bowel movement. Average LOH was 4.9 days for all patients. Patients were divided into quartiles (< 3 days, 3-5 days, 5-7 days, > 7 days) based on their LOH, and their charts were retrospectively reviewed for preoperative, intraoperative, and postoperative factors associated with their LOH., Results: Age at surgery, gender, the need for tube feeds, and specific underlying neuromuscular disorder were not significant predictors of LOH; however, severely involved cerebral palsy (CP) patients (GMFCS 4/5) were more likely to have extended stays than GMFCS 1-3 patients (p = 0.02). Radiographic predictors of LOH included major coronal Cobb angle (p = 0.002) and pelvic obliquity (p = 0.02). Intraoperative predictors included longer surgical times, greater numbers of levels fused and need for intraoperative or postoperative blood transfusion (p < 0.05). The need for ICU admission and development of a pulmonary complication were significantly more likely to fall into the extended LOH group (p < 0.05)., Conclusions: Several variables have been identified as significant predictors of LOH after PSF for NMS in the setting of a standardized discharge pathway. Patients with smaller curves and less complex surgeries were more amenable to accelerated discharge. Conversely, patients with severe CP with large curves and pelvic obliquity requiring longer surgeries with more blood loss may not be ideal candidates. These data can be used to inform providers' and families' post-operative expectations., Level of Evidence: Therapeutic Level III.
