The purpose of this study was to compare PONV rates and the quality of recovery between patients undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA) under spinal anesthesia receiving conventional antiemetics alone and those receiving antiemetics combined with use of a transcutaneous electrical acupoint stimulation bracelet (EmeTerm; WAT Medical Enterprise).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Patients at moderate or high risk for PONV, including 195 patients undergoing THA and 153 patients undergoing TKA, were randomized to receive routine antiemetics (dexamethasone and ondansetron) alone or with use of the EmeTerm bracelet.

Use of the bracelet reduced the risk of PONV within 24 hours by 61% (adjusted hazard ratio, 0.39; 95% confidence interval [CI], 0.24 to 0.63), and its benefit became significant at 0 to 3 and 3 to 6-hour intervals after surgery. The complete response rate was higher for the bracelet + antiemetics group compared with the group with antiemetics alone (84.0% compared with 68.8%; p = 0.001), with better Quality of Recovery scores at 24 hours in the bracelet + antiemetics group.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>The EmeTerm bracelet enhanced the efficacy of antiemetics in reducing PONV after THA and TKA under spinal anesthesia and may improve short-term recovery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence:<\/jats:title>\n                    <jats:p>\n                      Therapeutic\n                      <jats:underline>Level I<\/jats:underline>\n                      .
