Factors affecting the the incidence of nausea and vomiting in patients after receiving intrathecal injection of anesthetic with morphine and anti-nausea and vomiting drugs in Banpong Hospital

Abstract

        The purpose of this descriptive research was to study the incidence of nausea and vomiting and factors influencing the occurrence of nausea and vomiting after receiving intrathecal injection of anesthetic mixed with morphine and anti-nausea and vomiting medication in Banpong Hospital. The sample consisted of 209 patients who received intrathecal injections of anesthesia mixed with morphine and medicine to prevent nausea and vomiting. The instruments used for data collection were anesthesia records and anesthesia complication assessment forms which was checked for content validity by 5 experts and obtained an index of consistency (IOC) between .60 -1.00.  Analyze data using descriptive statistics and logistic regression analysis statistics.

        The result showed that the incidence of nausea and vomiting after surgery was 38.27 %, with 12.44 % occurring in the operating room, 12.92 % occurring in the recovery room, and 20.10 % occurring after 1 day of anesthesia. Factors influencing postoperative nausea and vomiting include: Those who received a lot of fluid in the recovery room were at 1.49 times higher risk than those who received less fluid. Every 1 class of ASA Class increased the risk was 2.17 times. The age group over 50 years old had a 2.87 times higher risk than those younger than 50 years old. Patients who had surgery and had a history of nausea and vomiting after surgery The risk is 7.094 times higher than patients who have had surgery but have no history of nausea and vomiting. The data obtained from this study can be used as a guideline for assessing the risk of postoperative nausea and vomiting for all patients prior to anesthesia.
