ABSTRACT
Objective To investigate the effhect of ultrasound-guided nerve block on the prognosis of patients undergoing laparoscopic cholecystectomy.Methods A total of 150 cases undergoing elective laparoscopic cholecystectomy in our hospital was used as the research object,and randomly divided into control (n =75) and observation (n =75) groups.The control group used punctured local infiltration analgesia,and observation group used the transversus abdominis plane block (TAP) combined with local infiltration analgesia hole.The postoperative awake time,hemodynamic changes,pain score,and analgesic use were compared between two groups.Results The recovery time was significantly reduced in the observation group (9.7 ± 2) minutes compared to the control group (23.9 ± 2.4) minutes.The additional total dose of analgesics and average additional times were significantly lower in the observation group compared to the control group (P ＜0.05).The pain score were 0.99 ±0.22 after waking,1.05 ±0.14 at the postoperative 6 h,1.13 ±0.23 at the postoperative 24 h,and 1.40 ±0.38 at the postoperative 48 h in the observation group,which was significantly lower than the corresponding 3.99 ± 0.36,3.67 ± 0.43,3.39 ± 0.38,and 3.93 ± 0.20 in the control group (P ＜ 0.05).With the postoperative time,postoperative 48 h in two groups of visual pain scores were significantly higher than that of 24 h after the operation (P ＜ 0.05).The incidence of adverse reactions was no significant difference between observation group (36％) and control group (32％) (P ＞ 0.05).Conclusions Ultrasound-guided nerve block can obviously reduce postoperative pain,reduce drug use frequency and dosage,significantly improve postoperative outcomes,and does not increase the incidence of adverse drug reactions.It is worthy of clinical reference.
