Development of a Management Model for Hyperemesis in Pregnant Women Through the "Vibratory Emesis Massage"

Hyperemesis gravidarum is a condition characterized by severe nausea and vomiting duringpregnancy that may affect nutritional status, fluid balance, and quality of life.Non‐pharmacological therapies such as acupressure and massage stimulation haveincreasingly been used as complementary approaches to reduce symptoms during pregnancy.This study developed a nursing intervention model called Vibratory Emesis Massage (VEM),which combines vibratory stimulation and acupressure at the Pericardium 6 (P6) pointusing a wearable wristband device. The intervention was designed to reduce nausea andvomiting symptoms in pregnant women through peripheral nerve stimulation and relaxationmechanisms.The study used a quasi‐experimental pretest‐posttest non‐equivalent control group designinvolving 240 pregnant women diagnosed with hyperemesis gravidarum at Prof. Dr.Chairuddin Panusunan Lubis Hospital, University of North Sumatra. Participants weredivided into intervention and control groups. The intervention group received VibratoryEmesis Massage therapy for 15‐20 minutes per session.The severity of nausea and vomiting was measured using the Pregnancy UniqueQuantification of Emesis (PUQE‐24) questionnaire before and after the intervention. Datawere analyzed using the Wilcoxon Signed‐Rank Test and Mann‐Whitney U Test to determinethe effectiveness of the intervention.The study aimed to provide evidence for the effectiveness of Vibratory Emesis Massage asa practical, safe, non‐invasive, and nurse‐led intervention for managing nausea andvomiting in pregnant women.
