BackgroundNausea and vomiting are common postoperative complications that occur within the first 24 h in adults. Clinical practice guidelines and a Cochrane review recommend stimulating the P6 acupoint to prevent or reduce postoperative nausea and vomiting. However, there are currently no standards and optimal timing is not known.ObjectivesThe purpose of this study was to evaluate the effect of acupressure application on the P6 acupoint, using acupressure wristbands, in the prevention of postoperative nausea and vomiting and the antiemetic drug requirement in patients who had high postoperative nausea and vomiting risk related to laparoscopic cholecystectomy.DesignThis was a longitudinal, randomized controlled clinical study.SettingsThe study was conducted in the general surgery department of a training and research hospital (105 beds), from March 2015 to March 2016.ParticipantsA total of 111 female patients who underwent laparoscopic surgery were divided into three groups of 37, using a block randomization method.MethodsTraining on acupressure wristband use was provided to the intervention group and an acupressure wristband with a plastic cap was placed at the P6 acupoint. A wristband with the same appearance as the acupressure wristband, but without a cap, was used in the placebo group. No intervention was used in the control group. The wristband was placed approximately one hour before the surgery and removed six hours after the surgery in both the intervention and placebo groups. The data were collected at the 2nd, 6th, and 24th postoperative hours.ResultsThe application of the acupressure wristband to the P6 acupoint in patients who underwent laparoscopic cholecystectomy was found to be more effective in decreasing the severity of nausea at the 2nd postoperative hour and the nausea incidence at 2-6 h, postoperatively, when compared to the placebo group (p < 0.05). However, there was no statistically significant difference between the intervention group and the control group. Therefore, acupressure application to the P6 acupoint was not found to be clinically effective in decreasing postoperative vomiting, antiemetic drug requirement, and in decreasing pain, anxiety, or the need for analgesic drugs (p > 0.05).ConclusionsWe did not find the stimulation of the P6 acupoint with an acupressure wristband to be clinically effective in reducing postoperative nausea and vomiting or antiemetic drug requirement in patients who underwent laparoscopic cholecystectomy.Copyright © 2018 Elsevier Ltd.
