Investigation of analgesic dose of nalbuphine combined with remifentanil after radical gastrectomy.

Clinical analgesic effect of different doses of nalbuphine combined with remifentanil on postoperative gastric cancer patients was explored. One hundred cases of gastric cancer patients treated from December 2014 to December 2016 in the Xiangyang No. 1 People's Hospital were selected and separated into group A and group B. The dose in group A was 0.2 mg/kg of nalbuphine plus 0.2 µg/kg of remifentanil, and 0.3 mg/kg of nalbuphine plus 0.1 µg/kg of remifentanil in group B. Analgesia was performed by self-controlled intravenous injection. The Visual Analogue Scale (VAS) pain scores and the Brinell Comfort Score (BCS) at 2, 6, 12, 24 and 48 h after operation, and the incidence of adverse reactions were compared between the two groups. The VAS scores in group A were higher than those in group B, but the BCS scores in group A were lower (P<0.05). Postoperative patient-controlled intravenous analgesia (PCIA) press times in group A were lower than those in group B (P<0.05); the incidence of adverse reactions such as nausea and vomiting in group A was higher than that in group B (P<0.05). The analgesic effect of intravenous analgesia scheme of 0.3 mg/kg of nalbuphine and 0.1 µg/kg of remifentanil on gastric cancer patients after operation is better than that of 0.2 mg/kg of nalbuphine and 0.2 µg/kg of remifentanil, which reduces the incidence of adverse reactions, has greater security, and can be promoted.
