Abstract:Objective To evaluate the effect of transversus abdominis plane block and rectus sheath block on postoperative pain relief and recovery. Methods Total 150 patients were randomized into control (C), levobupivacaine (L) and levobupivacaine plus morphine (LM) groups. All the patients received TAPB and RSB with saline, levobupivacaine or levobupivacaine plus morphine. The intraoperative opioids consumption, postoperative pain score, time to first analgesic use, postoperative recovery, including the times of first exhaust, defecation, oral intake and off-bed activity, the incidence of postoperative nausea and vomiting and antiemetics, and the satisfaction score were recorded. Results The use of remifentanil and postoperative recovery time of levobupivacaine group and levobupivacaine combined with morphine group were less than those of the control group (P < 0.05); the VAS score of levobupivacaine combined with morphine group was lower than that of the control group (P < 0.05), and the vas of levobupivacaine combined with morphine group was lower than that of levobupivacaine group (P < 0.05) 4-72 hours after operation; the cough vas of the combined morphine group was lower than that of the levobupivacaine group (P < 0.05); the time of the first use of analgesics in the control group was shorter than that in the levobupivacaine group and the levobupivacaine combined morphine group (P < 0.05); the total consumption of morphine in the levobupivacaine combined morphine group was less than that in the control group (P < 0.05), and the control group was less than that in the levobupivacaine group (P < 0.05); compared with the control group, the first time of defecation, defecation and leaving bed in the group of levobupivacaine combined with morphine was shorter (P < 0.05); the first time of eating and antiemetic dosage in the group of levobupivacaine combined with morphine was lower (P < 0.05); the satisfaction score in the group of levobupivacaine combined with morphine was higher than that in the group of levobupivacaine and the control group (P < 0.05). Conclusions The use of levobupivacaine combined with morphine for rectus sheath and transverse fascia plane nerve block can alleviate postoperative pain, reduce the use of analgesics, and promote the recovery of patients.
