Randomized Controlled Trial[Three subanaesthetic dose ketamines mixed with butorphanol in the postoperative continuous intravenous analgesia].
To determine an optimal clinical dose of ketamine after comparing the efficacy and security of 3 low dose ketamines mixed with butorphanol in the postoperative continuous intravenous analgesia. ⋯ Ketamine in subanaesthetic dose added to butorphanol for postoperative continuous intravenous infusion has a better postoperative analgesic effect and sedation. It can effectively spare butorphanol consumption without increasing adverse effects. The optimal combined dose is 90-120 microg/(kg x h).
