The Application Effect of Ultrasound-guided Superior Laryngeal Nerve Block in Plasma Resection of Pediatric Tonsils and Adenoids
Objective:To explore the application effect of ultrasound-guided superior laryngeal nerve block in plasma resection of pediatric tonsils and adenoids.Method:Sixty children who underwent plasma resection of tonsils and adenoids at Liuzhou Maternity and Child Healthcare Hospital from August 2022 to March 2023 were selected.They were divided into control group and observation group with 30 cases in each group by random number table method.The control group received routine tracheal intubation general anesthesia,while the observation group received ultrasound-guided superior laryngeal nerve block combined with general anesthesia.The hemodynamic indicators[heart rate (HR),mean arterial pressure (MAP)]of the two groups were compared after entering the operating room (T0),immediately after glottis insertion with visual laryngoscope (T1),immediately after trachea insertion (T2),and 3 min after intubation (T3).The intubation time,extubation time,postanesthesia care unit (PACU) residence time and coughing grade of the two groups were compared.The scores of pediatric anesthesia emergence delirium scale (PAED) at 10,20,30 min after entering PACU were compared between two groups.Result:HR and MAP at T1,T2 and T3 of two groups were higher than those at T0,but those of the observation group were lower than those of the control group,with statistical significance (P<0.05).The extubation time and PACU residence time in observation group were shorter than those in control group,the differences were statistically significant (P<0.05).The coughing grade of the observation group was better than that of the control group,the difference was statistically significant (P<0.05).Conclusion:The use of superior laryngeal nerve block during plasma resection for pediatric tonsils and adenoids has a relatively small impact on hemodynamics,reduces the incidence of agitation during the recovery period,and is relatively safe.
