Background:There continues to be a significant focus on the value of regional and neuraxial anesthesia techniques for adjunctive use when combined with general anesthesia. The reported advantages include decreased patient opiate exposure, decreased medication-related adverse effects, decreased postanesthesia recovery room time and hospital stay, and increased patient satisfaction.Materials and Methods:The authors present a case-controlled series evaluating the use of a single caudal epidural injection prior to incision as an adjunct to general anesthesia for the open repair of slipped capital femoral epiphysis. Opiate consumption, pain scores, and hospital stay were compared between the two cohorts of 16 adolescent patients. All patients received a demand-only patient-controlled opiate delivery system.Results:Although the failed block rate was high (31%), there was decreased opioid use in the perioperative arena as well as during the first 24 postoperative hours in patients who had a successful caudal epidural block. Furthermore, discharge home was possible in 27% of patients who received a caudal epidural block compared to 0% of patients who did not receive a caudal block.Conclusion:The potential utility of caudal epidural block as an adjunct to general anesthesia during major hip surgery in adolescents is presented. Factors resulting in a failed block in this patient population as well as the use of the ultrasound as an added modality to increase block success are reviewed.
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.
