Abstract
Introduction
Perioperative transcutaneous pericardium 6 (P6) electrical stimulation is effective for prevention of postoperative nausea and vomiting (PONV). The patients undergoing breast cancer surgery have a high PONV prevalence; however, the effectiveness of P6 stimulation in this surgical population has not been investigated.
Materials and methods
A total of 198 patients undergoing mastectomy under general anesthesia were enrolled. They were randomly assigned to the one of three treatments: P6 stimulation + dexamethasone (group PD, n = 66), granisetron + dexamethasone (group GD, n = 66), and dexamethasone alone (group DM, n = 66). The primary endpoint was the incidence of postoperative vomiting (POV) within postoperative 48h. The secondary endpoints included the use of rescue antiemetic, severity of POV, and the incidence of postoperative nausea and other adverse events.
Results
The incidence of POV in group PD (9.1%) was similar to group GD (10.6%, P = 0.770), but significantly lower than that in the group DM (28.8%, P = 0.004) within postoperative 48 h. And, the incidence of postoperative nausea was similar between group PD and group GD but lower than that in group DM. The use of rescue antiemetics had no statistical differences among the three groups. The median (interquartile range) scores of POV severity were higher in group GD [6.0 (5.0, 7.0)] than in group DM [4.0 (3.0, 6.0), P = 0.012] within postoperative 48 h, but similar to group PD [5.5 (4.0, 6.3), P = 0.208].
Conclusions
Combined with dexamethasone, P6 stimulation has similar effectiveness for PONV prophylaxis with 5- hydroxytryptamine 3 antagonist granisetron but lower cost of antiemetic use. Moreover, both groups had a lower incidence of PONV and higher satisfaction than dexamethasone alone in patients undergoing breast cancer surgery.

The Journal of Surgical Research: Clinical and Laboratory Investigation publishes original articles concerned with clinical and laboratory investigations relevant to surgical practice and teaching. The journal emphasizes reports of clinical investigations or fundamental research bearing directly on surgical management that will be of general interest to a broad range of surgeons and surgical researchers. The articles presented need not have been the products of surgeons or of surgical laboratories.
The Journal of Surgical Research also features review articles and special articles relating to educational, research, or social issues of interest to the academic surgical community.
