Presentation of a Nonpharmacological Approach to Prevent Nausea and Vomiting in Cesarean Section with Spinal Anesthesia

Background and Objectives: Acupressure is used as a noninvasive technique in the treatment of some types of diseases and some pathological conditions. The aim of this study, was to evaluate effects of a nonpharmacological approach (acupressure) in comparison to metoclopramide (pharmacological agent) in prevention of nausea and vomiting in pregnant patients who are at risk for gastric contents aspiration, because of gastrointestinal physiological changes during pregnancy. Materials and Methods: This study was an applied, descriptive and double blind study. Patients were divided in three groups. Group one patients, were the study group, in which pressure was applied using a wrist band and a bottom underneath 2 inches proximal to the wrist crease between the tendons of muscles flexor carpi redialis and palmaries longus (P6). Gruop two, included patients with placebo wrist band, received 10 mg metoclopramide intravenously. Group three patients, a group with placebo band, received 2 mL normal saline solution intravenously. Results of true acupressure group were compared with metoclopramide and saline normal placebo groups (wrist bands). Information was collected using a questionnaire, and results were analyzed by SPSS Win programme. Results: Results of this study revealed that the rate of nausea in both acupressure and metoclopramide groups was 16% and about 56% in normal saline group. Vomiting was observed in about 8% of cases in acupressure-metoclopramide group and in about 28% in normal saline group. Conclusion: These findings suggest that pressure applied on P6, is as useful as metoclopramide in preventing nausea and vomiting, and it is recommended for clinical use, because of absence of any side effects.
