The Application Of Laryngeal Mask Combined With Brachial Plexus Block For Upper Extremity Surgery In Pediatric Anesthesia

Pediatric surgery, often requires general anesthesia, pediatric risk of anesthesia is poorly tolerated, and improving the safety in pediatric anesthesia, is an important task in clinical anesthesia, by the anesthesia complications caused by respiratory factors during pediatric anesthesia, is the mainreason for the accident. How to ensure the pediatric perioperative safety has longly been a difficult problem for the anesthesiologists to solve.Objective: To investigate the results of hemodynamic changes,the recovery time, the postoperative adverse reaction, the time of using analgesic drugs after operation and the incidence of postoperative sore throat of pediatric patients with general anesthesia who were randomly dividedinto 3 groups,group A(endotreacheal intubation),group B(laryngeal mask) and group C( laryngeal mask combined with brachial plexus block), ascertain whether anesthesia in laryngeal mask combined with brachial plexus block have an advantage over other anesthesia methods for upper extremity surgery in pediatric anesthesia.Methods: All of the pediatric patients undergoing upper extremity surgery were randomly divided into 3 groups,group A(endotreacheal intubation),group B( laryngeal mask) and group C(laryngeal mask combinedwith brachial plexus block).Changes in MAP, HR and SPO2 were observed and recorded at the time before induction(T0), the time immediately after inserting a laryngeal mask or endotreacheal tube(T1),the time of the beginning of the operation(T2),30 minutes later of the operation(T3), the time at the end of the operation(T4),the time of removing the laryngeal mask or endotreacheal tube(T5),The recovery time, the postoperative adverse reaction, the time of using analgesic drugs after operationand the incidence of postoperative sore throat of pediatric patients were also observed and recorded.Results: The results of hemodynamic changes,and the time of usinganalgesic drugs after operation and the incidence of postoperative sore throat in group B and group C were better than that in Group A.There were significant differences between group B and group C about the result of the recovery time and the time of using analgesic drugs after operation in,and the result of Group C is superior to Group B, even better than Group AConclusion: The application of laryngeal mask combined with brachial plexus block for upper extremity surgery in pediatric anesthesia is a safe method,with less side effects,quick recovery and good controllability.
