Abstract:

Objective To investigate the analgesic effect of ropivacaine transverse abdominal muscleplane block（TAPB）combined with patient⁃controlled intravenous analgesia（PCIA）after surgical treatment for external abdominal hernia. Methods A total of 94 patients undergoing abdominal external hernia surgery in our hospital from July 2019 to September 2021 were selected as study subjects and randomly divided into two groups. The control group（47 patients）received PCIA postoperatively，while the study group（47 patients）received additional ropivacaine TAPB analgesia on the basis of the control group. The general condition，pain scores［visual analog scale（VAS）］and sedation scores（Ramsay scale）at 2 h，6 h，12 h，24 h and 48 h after surgery，total number of PCIA compression ，total amount of infusion ，and adverse reactions were comparedbetweenthe two groups. Results There were no differences in gender，age，bodyweight，andsurgical duration between the two groups（P > 0.05）. The VAS scores increased initially and then decreased at 2 h，6 h，12 h，24 h and 48 h postoperativelyin both groups（P < 0.05）. Ramsay scores decreased gradually（P < 0.05）. VAS scores at 6 h，12 h，24 h and 48 h were lower in the study group than in the control group（P < 0.05），but there were no differences in Ramsay scores at the above time points（P > 0.05）. The total number of PCIA compression and total amount of infusion were smaller in the study group 48 h after surgery（P < 0.05）. There was no difference in the total incidence of adverse reactions between the two groups（P > 0.05）. Conclusions Ropivacaine TAPB combined with PCIA has a more significant analgesic effect than PCIA alone after surgical treatment for abdominal external hernia. This combined therapycan reduce the total number of PCIA compressionand amount of infusion volumeand it has bettersafety.
