Abstract
Objective To observe the gastrocnemius muscle tendon stimulation effect for diagnosis spinal function in scoliosis surgery for children. Methods 20 scoliosis patients were randomly divided into gastrocnemius muscle tendon stimulation group and traditional wake-up test group. All patients were induced with propofol,remifentynil, cisatracurium and maintained with propofol, remifentynil and isofrane. Spinal function changes were observed postoperatively in two groups. Results After the operation, all patients' spinal function was normal. The MAP, HR of wake-up group were (62.6±3.4) mmHg, (92.6±7.6) bpm respectively before anaesthesia, and were (76.6±7.3) mmHg, (132.6±13.4) bpm respectively at the wake-up time (P＜0.05). The MAP, HR of gastrocnemius muscle tendon stimulation group were (63.3±3.2) mmHg, (95.6±6.3) bpm respectively before anaesthesia, and were (68.7±5.4) mmHg, (112.6±9.5) bpm respectively at the wake-up time(P＞0.05). The patients of wake-up group needed (842±65) s to come round, while the ones of gastrocnemius muscle tendon stimulation group need (465±71)s. Conclusion Gastrocnemius muscle tendon stimulation may be an effective method to evaluate the spinal function during scoliosis surgery in children.
