ObjectiveTo compare the analgesic effects and incidence of postoperative adverse events after the erector spine plane (ESP) and transversus abdominis plane (TAP) blocks in patients undergoing laparoscopic cholecystectomy (LC).MethodsIn this retrospective observational study, clinical data of 103 patients undergoing LC in Changxing County People's Hospital from October 2020 to October 2022 were retrospectively reviewed, and the patients were divided into ESP-group (n=56) and TAP-group (n=57) based on the block method. The operation time, the change of visual analogue scale (VAS) score of static (sVAS) and dynamic (dVAS) pain after operation, the patient-controlled dose, and the remedial analgesic dose at 24 hours after the operation were compared between the two groups. The occurrence of postoperative adverse reactions in both groups was recorded.ResultsThe dVAS scores of the ESP-group at one hour, three hours, six hours, and 12 hours after the operation were lower than those of the TAP-group (P<0.05). The patient-controlled dose and remedial analgesia dose of the ESP-group were significantly lower than those of the TAP-group (P<0.05). There was no difference in the incidence of postoperative nausea and vomiting between the two groups (P>0.05).ConclusionsESP block and TAP block in LC patients have similar operation time and incidence of postoperative adverse events such as nausea and vomiting. However, short-term postoperative analgesic effect of ESP block is superior to TAP and requires a lower dose of analgesia.Copyright: © Pakistan Journal of Medical Sciences.
