Observation on therapeutic effect of compound anesthesia of transcutaneous electrical point stimulation and Remifentanil / 中国针灸

ABSTRACT

<p><b>OBJECTIVE</b>To assess the value of compound anesthesia of transcutaneous electrical point stimulation and Remifentanil and the efficacy of this method on postoperative acute pain.</p><p><b>METHODS</b>Sixty cases with vertebral lamina internal fixation decompression operation were selected and randomly divided into 2 groups, an observation group and a control group, 30 cases in each group. The patients in the observation group received compound anesthesia of transcutaneous electrical point stimulation at Hegu (LI 4), Laogong (PC 8), Neiguan (PC 6) and Waiguan (TE 5) 30 min before anesthesia induction with HANS stimulator and then Remifentanil anesthesia. During the operation, the stimulation was lasted for 30 min and ceased for 30 min until the end of operation. The patients in the control group received simple Remifentanil anesthesia. The dosage of the narcotic, changes of both blood pressure and heart rate during operation, before and after extubation and the pain degree, etc. were investigated in the two groups.</p><p><b>RESULTS</b>(1) The dosage of Isoflurane, (0.52 +/- 0.33)vol%, in the observation group was significantly lower than (1.12 +/- 0.18) vol% in the control group (P < 0.01). (2) Both blood pressure and heart rate during operation, before and after extubation in the observation group were lower than those before operation (P < 0.01), and both the blood pressure and heart rate during operation in the control group were lower than those before operation (P < 0.01). The blood pressure after extubation in the observation group was significantly lower than that of the control group (P < 0.01), and the heart rate before and after extubation in the observation group was significantly lower than that of the control group (P < 0.01). (3) The time of extubation and palinesthesia in the observation group were significantly shorter than those in the control group (P < 0.01). (4) In the observation group, the VAS scores after palinesthesia in 26 cases were < 4, and in 4 cases were > or = 5, while in the control group, the scores in 4 cases were < 4 and in 20 cases > or = 5, with a significant difference between the two groups (P < 0.01).</p><p><b>CONCLUSION</b>Compound anesthesia of transcutaneous electrical point stimulation and Remifentanil can reduce the dosage of narcotics, shorten the time of palinesthesia and effectively prevent and treat acute pain after Remifentanil anesthesia.</p>
