Abstract

Study designRetrospective case series.ObjectivesThis study aimed to determine the prevalence and risk factors for orthostatic hypotension (OH) in adolescents undergoing posterior spinal fusion for spinal deformity correction.MethodsThe data of 282 consecutive adolescents who underwent posterior spinal fusion for spinal deformity correction in our center over 12 months were retrieved. Patient characteristics, including whether laminectomy or osteotomy was performed during the surgery, the occurrence of postoperative nausea and vomiting (PONV), perioperative hemoglobin albumin changes, perioperative blood transfusion, length of bed rest, willingness to ambulate, length of postoperative exercises of the lower limbs, and length of hospital stay, were collected and compared statistically between patients who did and did not develop postoperative OH.ResultsOf 282 patients, 197 (69.86%) developed OH postoperatively, and all cases completely resolved 5 days after the first out-of-bed exercises. Significant differences in the incidence of PONV, the willingness to ambulate and the length of postoperative exercises of the lower limbs were observed. The mean length of hospital stay of the patients with OH was longer than that of the patients without OH.ConclusionOur study suggests that temporary OH is a common manifestation following posterior spinal fusion for spinal deformity correction in adolescents. Postoperative OH may increase the length of hospital stay in these patients. Patients with PONV, who are not willing to ambulate and who perform postoperative lower limb exercises for a shorter time are more likely to have OH.

Summary

Introduction

Orthostatic hypotension (OH), which is when a patient’s blood pressure falls when moving from a supine position to a standing position, is a common cardiovascular disorder. It is defined as a decrease in the systolic blood. An association between OH and many types of surgeries, including cervical spine surgery, has been reported [3, 6, 7]. To date, no studies have studied the association between OH and posterior spinal fusion surgeries for the treatment of adolescent spinal deformities. We conducted this study to evaluate the prevalence and risk factors for OH in adolescent patients undergoing posterior spinal fusion for spinal deformity correction
