Abstract:
Objective:To compare the safety and efficacy of continuous transversus abdominis plane (CTAP) block and patient-controlled intravenous analgesia (PCIA) in abdominal surgery postoperatively.Methods:PubMed, Embase, Web of Science, CNKI and other English and Chinese databases were searched since their establishment to February 2021 with "continuous/modified, transversus/transverse abdominis plane block, TAP block, patient controlled analgesia, patient-controlled analgesia, patient controlled intravenous analgesia, patient-controlled intravenous analgesia, PCA/PCIA/IV-PCA" as the search keywords. According to the analgesia treatment methods, patients were divided into continuous transversus abdominis plane block group (CTAP group) and patient-controlled intravenous analgesia group (PCIA group). Review Manager 5.4 software was used to conduct a Meta-analysis on outcome indicators such as postoperative nausea and (or) vomiting (PONV), dizziness, pain score and recovery status after abdominal surgery. Risk ratio ( RR) was calculated for counting data, Mean ± SD was calculated for measurement data. Heterogeneity was measured by I2, and related data were analyzed by using either a fixed effects model or a random effects model. Results:(1) The results of literature search: A total of 6 randomized controlled trials, including 2 published in English and 4 published in Chinese were analyzed, involving 479 patients. The results of the Meta-analysis: Compared with PCIA, CTAP block had lower incidence of PONV ( RR=0.22, 95% CI: 0.08-0.62, P<0.01), lower incidence of dizziness ( RR=0.27, 95% CI: 0.09-0.79, P=0.02), lower pain scores on movement at 24 h ( MD=-0.75, 95% CI: -1.42--0.08, P=0.03) and 48 h ( MD=-0.68, 95% CI: -1.05--0.31, P<0.001) postoperatively, and earlier time of first mobilization ( MD=-0.49, 95% CI: -0.69--0.30, P<0.001) and first exhaust ( MD=-10.47, 95% CI: -13.53--7.41, P<0.001), with statistically significant differences. However, there were no statistically significant differences in pain scores at rest at 24 h ( MD=-0.25, 95% CI: -0.57-0.08, P=0.14) and 48 h ( MD=-0.15, 95% CI: -0.39-0.09, P=0.22) postoperatively and postoperative length of hospital stay ( MD=-1.01, 95% CI: -2.28-0.26, P=0.12). Conclusion:CTAP block is a relatively safe and effective analgesic method, and it′s more consistent with the concept of enhanced recovery after surgery (ERAS) and can be recommended as an alternative method of PCIA.
