Application of ultrasound-guided transversus abdominis plane block in postoperative analgesia for laparoscopic gynecological surgery

Objective To investigate the clinical value of ultrasound-guided transversus abdominis plane block for postoperative analgesia in patients with gynecological benign diseases undergoing laparoscopic surgery. Methods Patients with benign gynecological diseases received laparoscopic surgery from January 2017 to January 2019 in Qinghai Communications Hospital were included in this study.The study group (n=60) received transversus abdominis plane block + PCA analgesia after operation,while the control group (n=60) used PCA analgesia alone.The general information,pain management and rehabilitation indicators of the two groups were analyzed. Results The average age of the study group was (43.9±6.7) years and it was (45.6±8.0) years in the control group.There was no significant difference in ASA grading,duration of anesthesia,operation mode between the two groups (all P>0.05).There was little difference in postoperative VAS score between the two groups.The dosage of sufentanil in the study group was less than that in the control group at 12 h and 24 h (P<0.05,respectively).The study group was superior to the control group in terms of the mean time to first analgesic use (172.7±83.2) min vs (47.5±26.9) min,the percentage of additional analgesics use (11.7% vs 43.3%),the incidence of PONV (8.3% vs 23.3%),the time of mobility (23.2±6.7) h vs (29.1±8.5) h and the average length of hospital stay (5.7±2.1) d vs (7.0±2.4) d (all P<0.05). Conclusion Ultrasound-guided transversus abdominis plane block reduces the amount of opioids used after laparoscopic surgery for benign gynecological diseases and accelerate the recovery process.
