Abstract
Objective To explore the analgesic effect of ultrasound guided transverse abdominis plane block combined with laryngeal mask general anesthesia on high ligation of hernia sac in children. Methods 150 children undergoing high ligation of hernia sac were randomly divided into the observation group (75 cases) and the control group (75 cases). The control group was treated with laryngeal mask general anesthesia, while the observation group was treated with ultrasound guided transverse abdominis plane block on the basis of the control group. The mean arterial pressure (MAP), heart rate (HR), restlessness and pain scores, recovery time, operative time and complications were compared between the two groups. Results The incidence of complications in the observation group was significantly lower than that in the control group (6.7% vs 17.3%, P 0.05). In the control group, there was no significant difference in MAP, HR when the laryngeal mask was inserted, the laryngeal mask was removed and before anesthesia induction (P>0.05). The MAP, HR at the beginning of operation in the control group was higher than that before anesthesia induction (P 0.05) when period before anesthesia induction, the laryngeal mask was inserted ,and after inserting laryngeal mask. At the beginning of operation, the MAP, HR of the observation group was lower than that of the control group (P<0.05). Conclusion Ultrasound-guided transverse abdominis plane block combined with laryngeal mask general anesthesia in high ligation of hernia sac in children can effectively reduce the operation time and postoperative recovery time, relieve postoperative pain and restlessness, and reduce the incidence of complications. It has great clinical application value.
