Abstract: Objective To examine analgesic effects of ultrasound-guided quadratus lumborum block(QLB) and transversus abdominis plane block(TAPB) on recovery from total abdominal hysterectomy. Methods Patients scheduled for total abdominal hysterectomy were randomly divided into two groups (n=30), group QLB and group TAPB. Patients in both groups were given patient-controlled intravenous analgesia (PCIA). Pain both at rest and during cough were quantified with VAS 4, 8, 12 h and 24 h after the operation. Information about diffusion of nerve block and the use of extra analgesic drugs, postoperative recovery and complications were also collected. Results QLB diffused to the regions innervated by the T7-L1 nerves, whereas TAPB affected regions innervated by T10-L1 nerves. Patients received QLB reported lower VAS scores during rest and cough than those received TAPB 12 h and 24 h after operation (P<0.05). No significant difference between QLB and TAPB groups was observed in the use of extra analgesic drugs 24 h after surgery, the incidence of nausea and vomiting, time to recovery of bowel function, etc (P>0.05). Conclusions QLB provides more effective analgesia than TAPB in patients undergoing total abdominal hysterectomy.
