Abstract:

Objective To investigate the effect of ultrasound-guided nerve block in laparoscopic cholecystectomy and its effect on postoperative pain. Method 62 patients who underwent laparoscopic cholecystectomy in Mianyang 404 Hospital from January 2020 to October 2021 were randomly divided into control group (31 cases, local infiltration analgesia) and observation group (31 cases, nerve block anesthesia and analgesia under ultrasound guidance). The clinical indexes, postoperative pain degree and adverse reactions of the two groups were analyzed. Result The recovery time of patients in the observation group was shorter than that in the control group; The dosage and frequency of additional analgesic drugs were less than those in the control group (P ＜ 0.05). The scores of visual analogue scale (VAS) in the observation group were lower than those in the control group at awake, 6h, 24h and 48h after operation (P ＜ 0.05). The incidence of postoperative adverse reactions in the control

group and the observation group were 6.45% and 12.90% respectively, with no significant difference (P ＞ 0.05). Conclusion The application of ultrasound-guided nerve block in patients undergoing laparoscopic cholecystectomy can not only shorten the postoperative recovery time, reduce the dosage and times of analgesic drugs, but also reduce the degree of postoperative pain.
