Study Design: Historically controlled clinical trial. Objectives: Patients presenting for correction of adolescent idiopathic scoliosis (AIS) by posterior spinal fusion may benefit from structured clinical pathways. We studied the effects of implementing a published clinical pathway for the perioperative care of patients with AIS that required intraoperative use of methadone at our institution. Methods: We performed a historically controlled clinical trial of patients undergoing posterior spinal fusion for AIS by comparing a retrospectively collected control group of 25 patients with a prospective experimental group of 14 patients receiving methadone, gabapentin, propofol, and remifentanil as part of a new clinical pathway. Results: Use of the pathway decreased average pain scores evaluated by the Numeric Rating Scale in the 24 hours following surgery (4.8 [4-6] to 3.4 [2-4], P = .03 [−2.6 to −0.2; t = −2.3]) and postoperative opioid consumption by 76% (41 [29-51] mg to 10 [4-17] mg, P < .001 [−45 to −15; Welch’s t = 4.9]) during the same period. Improved analgesia and reduced reliance on opioids facilitated other postoperative elements of the clinical pathway and shortened the average hospital length of stay by 1 day (4 [3-6] days to 3 [3-5] days, P = .001 [−2 to −1; U = 67, Z = −3.3]). Conclusions: Multimodal analgesia and a clinical pathway add value in the perioperative care of patients undergoing posterior spinal fusion for AIS by improving analgesia and shortening hospitalization. The prospective arm of the trial was registered at clinicaltrials.gov under NCT02481570.
INTRODUCTION: Oral carbohydrates (CHO) prior to a variety of surgical procedures has been found to attenuate the postoperative catabolic state with an improvement in well-being insulin sensitivity, cardiac output and shortened hospital stays without adverse effect. Previous work has compared oral CHO to water or flavored water and excluded pregnant women. Our primary aim was to determine if preoperative oral consumption of higher dose CHO would improve patient well-being (WB-VAS) prior to cesarean section compared to a widely available rehydration beverage with a lower CHO dose and fasted controls. METHODS: Low risk women undergoing scheduled cesarean deliveries under spinal anesthesia were recruited. Participants were randomized to either: Clearfast® (group CHO), Gatorade Thirst Quencher® (group R) or fasting control (group F). Participants in groups CHO and R received 710 mL of either beverage the night before and 355 mL two hours prior to surgery. Participants in Group F fasted after midnight the night before surgery. Two hours before surgery, baseline WB-VAS was recorded, followed by beverage consumption for groups CHO and R. One hour later, WB-VAS was repeated. Additional recorded measures included umbilical blood glucose, intraoperative variables, breastfeeding success, and quality of recovery one day after surgery. RESULTS: Group differences in change in WB-VAS were analyzed using linear regression. Both group CHO and R showed significant improvements in WB-VAS while fasted patients showed no change. There were no differences in other outcomes. CONCLUSION: Either the common oral rehydration or higher dose CHO beverage resulted in superior well-being compared to fasting with no difference in other outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
