Abstract:
Objective To observe the effects of transcutaneous electrical acupoint stimulation (TEAS) on anesthetic dosage, blood pressure, heart rate, oxygenation and adverse reactions during painless gastroscopy under the monitoring of Consciousness Index. Methods 300 patients undergoing painless gastroscopy were randomly divided into TEAS group, sufentanil group and control group with 100 cases in each group. All patients were monitored for consciousness index, blood pressure, heart rate and oxygenation. Gastroscopy was performed when IOC1 was maintained at 40-60 and IOC2 at 30-50. Sufentanil group: TEAS group: 10 minutes before entering the operating room TEAS right Hegu, Neiguan, Zusanli and Liangqiu point until the end of the examination. Normal saline 0.5 mL and 1% propofol 0.15-0.25 mL/kg were injected intravenously after entering the operating room. Sufentanil 0.05 μg/kg, 1% propofol 0.15-0.25 mL/kg were given intravenously. Control group: Normal saline 0.5 mL and 1% propofol 0.15-0.25 mL/kg were injected intravenously after entering the operating room. Mean arterial pressure (MAP) , heart rate (HR) and Oxygenation were recorded before propofol administration (T1), 1 min after propofol administration (T2), at endoscopy (T3) and at the end of gastroscopy (T4), the incidence of hypotension, hypertension, hypoxemia, body reaction, injection pain, nausea and vomiting and the time of recovery were observed. Results The mean arterial pressure, heart rate at T3, propofol dosage, injection pain and the incidence of intraoperative hypotension in the TEAS group were significantly lower than those in the control group(P <0.05), there was no difference with the Sufentanil group(P >0.05). The incidence of hypoxemia in TEAS group was lower than that in Sufentanil group and control group (P <0.05). The incidence of postoperative nausea and vomiting in sufentanil group was significantly higher than that in TEAS group and control group(P <0.05). There was no difference in the kinesthetic response among the three groups(P >0.05). Conclusion TEAS can reduce the dosage of propofol in gastroscopy and reduce the incidence of adverse reactions.
