RESUMO
Objective To investigate the effect of pre injection of penehyclidine hydrochloride on the airway gland secretion of children with laparoscopic inguinal hernia surgery under general anesthesia.Methods 72 cases of children undergoing laparoscopic inguinal hernia surgery under general anesthesia in pediatric surgery department in our hospital were selected and divided into two groups,grouped by random number table method,control group of 36 cases were treated with preoperative injection of atropine,the experiment group of 36 cases were treated with preoperative injection of penehyclidine hydrochloride.Heart rate on pre injection(T0),before induction of anesthesia(T1),five min after induction(T2),ten min after induction(T3)and extubation(T4),the airway gland secretion,respiratory function related indexes,and the incidence of adverse reactions were compared.Results Compared with the control group,re fixed rate of tracheal tube during operation and the incidence of choking tube at T4 time were lower,the levels of PIP、Raw were lower and the level of CL was higher on five min after intubation,the HR at T1,T2,T3,T4 time was lower,with statistical significance(P<0.05);the incidence of adverse reactions in the control group 30.56％was higher than the experiment group 11.11％,with statistical significance(P<0.05).Conclusion Pre injection of penehyclidine hydrochloride can inhibit airway gland secretion in children with laparoscopic inguinal hernia surgery under general anesthesia,protect the respiratory function,and does not increase heart rate,the safety was higher.
