Application Of Ultrasound-guided Bilateral Rib Marginal Transversus Abdominis Plane Block In Laparoscopic Appendicectomy In Children

OBJECTIVE: To observe the analgesic effect of ultrasound-guided bilateral rib marginal transversus abdominis plane block on laparoscopic appendicectomy in children.METHODS: Seventy-four children underwent laparoscopic appendicectomy,aged 4 to 10 years,and ASA grade I.Randomized into ultrasound-guided bilateral costal transversus abdominis plane block(T group)and control group(R group),37 cases in each group,T group underwent conventional general anesthesia under ultrasound guided bilateral rib TAP block,control group(R group)underwent routine general anesthesia.Separately recorded vital signs at the establishment of pneumoperitoneum(T1),and 5 min(T2),10 min(T3),20 min(T4)after the establishment of pneumoperitoneum,and the end of surgery(T5).Evaluated m-CHEOPS score,agitation,analgesic medication in the PACU,postoperative adverse reactions and parental satisfaction.RESULTS: There was no statistically significant difference in age,weight,and operation time between the two groups.In group T,the heart rate,blood pressure,m-CHEOPS score and the score within 10 minutes after the establishment of pneumoperitoneum,the incidence of agitation,and the PACU administration of analgesic drugs were significantly lower.Postoperative adverse reactions was no significant difference between the two groups.Conclusion: Ultrasound-guided bilateral costal transversus abdominis plane block is beneficial to maintain hemodynamic stability during laparoscopic appendicectomy in children,and can effectively reduce the incidence of pain and agitation during staying in PACU.
