Summary
The purpose of this study is to evaluate if the addition of P6 pressure point stimulation as opposed to sham-point stimulation will decrease intraoperative and postoperative nausea and vomiting (IONV and PONV) for patients undergoing non-emergent cesarean delivery. We hypothesize that the addition of stimulation of the P6 pressure point to our institutional current standard of care (phenylephrine infusion, intravenous fluid bolus, and as needed intraoperative ondansetron) will decrease the occurrence of intraoperative emesis.
