Medicated plaster at Dazhui (GV 14) for preventing perioperative hypothermia in patients undergoing PKRP and ureteroscopic laser lithotripsy

Abstract

To observe the preventive effect of medicated plaster at Dazhui (GV 14) on preventing perioperative hypothermia in patients undergoing plasmakinetic resection of prostate (PKRP) and ureteroscopic laser lithotripsy. A total of 300 patients with ASA gradeⅠorⅡreceiving ureteroscopic laser lithotripsy or PKRP under total intravenous anesthesia (TIVA) were randomly divided into an observation group and a control group, 150 cases in each group. The patients in the control group received routine heat preservation measures, while on the basis of the control group, the patients in the observation group were treated with medicated plaster at Dazhui (GV 14) 30 min before operation. The temperature (ear temperature), mean arterial pressure (MAP), heart rate and blood oxygen saturation (SpO2) at each time point (resting state before operation, 5, 10 min into operation, at the end of operation, 5 and 10 min after operation) were recorded; the number of hypothermia, the classification of postoperative shivering degree, operation time, propofol dosage, intraoperative infusion volume and intraoperative flushing fluid volume were recorded. The temperature at 5 and 10 min into operation as well as at the end of operation in the two groups was all lower than that before operation and at previous time point (P<0.01). The temperature at 5 and 10 min after operation in the two groups was all higher than that at previous time point (P<0.01), but still lower than that before operation (P<0.01). The temperature at 10 min into operation, at the end of operation, 5 and 10 min after operation in the observation group was higher than that in the control group (P<0.01, P<0.05). The total incidence rate of hypothermia in the observation group was 2.0% (3/150), which was significantly lower than 13.3% (20/150) in the control group (P<0.01). The total incidence rate of shivering was 18.0% (27/150) in the observation group and 28.7% (43/150) in the control group (P>0.05). The medicated plaster at Dazhui (GV 14) can effectively prevent perioperative hypothermia and improve comfort in patients undergoing PKRP and ureteroscopic laser lithotripsy.
