Effect Of Transversus Abdominis Plane Block On Efficacy Of Postoperative Analgesia In Overweight Gynecological Patients

Objective:To investigate the advantages of transversus abdominis plane block(TAPB)in overweight patients by comparing the postoperative outcomes of normal patients with those of overweight patients.Methods:A total of 120 patients undergoing laparoscopic myomectomy were selected.The normal Body mass index(BMI,18.5kg/m~2 ≤ BMI ≤ 23.9kg/m~2)group was randomly divided into G(General anesthesia)group and TG(TAPB+General anesthesia)group;and the overweight group(24.0kg/m~2 ≤ BMI ≤ 27.9kg/m~2)was randomly divided into OG(Overweight+General anesthesia)group and OTG(Overweight+TAPB+General anesthesia)group.All the patients in the four groups were operated under general anesthesia.The difference was that the TG group and the OTG group were first treated with TAPB between pre-anesthesia,and then received routine general anesthesia.Postoperative VAS(1,4,6 and 24 hours),the time of analgesia pump presses after the operation within 24 hours,the time of first getting out of bed activity,the time of first exhaust and the number of days of postoperative hospitalization were recorded for analysis and comparison in 4 groups.Results:Compared with group G,the VAS at 1,4 and 6 hours after surgery were higher in group OG,and the difference was statistically significant(P < 0.05).There was no significant difference in VAS between OTG group and TG group at the same time after surgery(P > 0.05).The number of pressing analgesia pump 24 h after surgery,the first time of getting out of bed,the first time of exhaust and the postoperative hospitalization days in OG group were higher than those in G group,and there was no statistical significance between OTG group and TG group(P > 0.05).Conclusion:For overweight patients who are already sensitive to pain,TAPB combined with general anesthesia can reduce postoperative VAS score,narrow the gap with normal BMI patients,and has a definite analgesic effect.It can promote the early movement of overweight patients out of bed,shorten the length of hospital stay,so as to provide a better direction and ideas for the postoperative recovery of overweight patients.
