Abstract:
Objective To evaluate the accuracy of monitoring the neuremuscular blockade intraoporatively by transcutaneous electrical stimulation at the P6 acupuncture point. Methods Thirty-five patients, ASA Ⅰ - Ⅲ, BMI≤35 kg/m2 scheduled for abdominal surgery were selected. Anesthesia was induced by sufentunil 0.2-0.3 μg/ kg iv, propofol 2,5-3.5 mg/kg iv. Neuromuscular monitoring was performed by TOF Watch SXR at the P6 acupuncture point on the left forearm and ulnar nerve on the right. The current intensity and gain were recorded frem all the patients;onset time, recovery time of TOF ratio 25% and TOF ratio 90% of atrucurium were also obtained by TOF stimulation on the P6 acupuncture point and the ulnar nerve in patients who were administered a single bolus of atracurium 0.5 mg/kg iv during operation. Controlled ventilation commenced after endotracheal intubation. Results There were no significant differences between the P6 acupuncture point and the ulnar nerve in stimulus intensity or gain ( P > 0.05 ). There were no significant differences between the P6 acupuncture point and the ulnar nerve in onset time, recovery time of TOF ratio 25% and TOF ratio 90% (P > 0.05).Conclusion Transcutaneous electrical stimulation at the P6 acupuncture point can be used to monitor neuromuscular blockade intraoperafively.
