Abstract:

Objective To evaluate the analgesic effect of quadratus lumborum block（QLB）and transver⁃ sus abdominis plane block（TAP）on patient undergoing cesarean section. Methods We searched literature from Pubmed，Cochrane，Embase，Web of Science，CNKI，WanFang and Weipu Databases for randomized controlled trials（RCTs）on different effects of QLB and TAP in cesarean section. Primary outcome was the Visual Analogue Score（VAS）at different time points and secondary outcome was the total consumption of sufentanil. Meta⁃analysis was performed with Review Manager 5.3. Results Seven RCTs were included. Compared with TAP group，QLB group had a decreased VAS score 4 h（MD = -0.32，95%CI：-0.56 ~ -0.07，P = 0.01），8 h（MD = -0.6，95%CI：-0.86 ~ -0.34，P < 0.000 01），12 h（MD = -0.81，95%CI：-1.34 ~ -0.27，P = 0.003），24 h（MD = -0.41，95%CI：-0.77 ~ 0.06，P = 0.02）at movement after surgery and a lower VAS score 12 h（MD = -0.3，95%CI：-0.55 ~ -0.06，P = 0.02）at rest after surgery. QLB group also experienced a less consumption of sufentanil. Conclusion QLB has a better analgesic effect than TAP after cesarean section at movement within 24 hours，and there is less consump⁃ tion of sufentanil.
