OBJECTIVE: To observe the effects of hydromorphone and morphine intravenous analgesia on plasma motilin and postoperative nausea and vomiting in patients undergoing a total hysterectomy.

PATIENTS AND METHODS: 80 patients who underwent hysterectomy from April 2015 to June 2016 were randomly divided into two groups, with 40 patients in each group. The two groups received an intravenous infusion of hydromorphone or morphine for analgesia. The VAS pain score and Ramsey sedation score were recorded 4, 8, 12, 24, and 48 hours after the first dose of analgesia. The scores of nausea and vomiting were recorded. The levels of motilin were determined by radioimmunoassay before anesthesia, after anesthesia, during hysterectomy and 1 day after the operation. The results showed that the analgesic effect of hydromorphone was more rapid than morphine.

RESULTS: There were significant differences in VAS scores between the two groups at each time point (p<0.05), indicating that the analgesic effect of hydromorphone was better than morphine’s one. The scores of Ramsay sedation were less than 6 points at each time point within 48 hours after the operation. The content of plasma motilin in the hydromorphone group was higher than that in the morphine group during the first day after anesthesia. There were 34 cases (85%) of mild nausea and vomiting within 24 hours after the operation in the hydromorphone group. In the morphine group, there were 16 cases (40%) of mild nausea and vomiting within 24 hours after the operation, 10 cases (25%) of severe nausea and vomiting.

CONCLUSIONS: The occurrence of severe malignant vomiting after the use of morphine was more than that after the use of hydromorphone. Normal level and function of motilin is the basis of avoiding nausea and vomiting. Too fast or too slow gastrointestinal motility can induce postoperative nausea and vomiting.
