Abstract
Objective To observe the nursing effect of 2% lidocaine and dexamethasone mixture in patients with vocal polyp extirpation under tracheal intubation. Methods From September 2017 to March 2018, 68 patients who were selected to perform vocal cord polyp resection under supportive laryngoscope in the hospital were randomly divided into 4 ml of 2% lidocaine before surgery and 2 ml of 0.5% dexamethasone after atomization inhalation with tracheal intubation under general anesthesia (observation group) and conventional tracheal intubation with general anesthesia (control group), 34 cases of each group.The hemodynamic indexes of endotracheal intubation and operation , the Self-rating Anxiety Scale (SAS) of Ricker at trachea extubation, BCS comfort score and wake time 15 minutes after endotracheal tube extubation were observed. Results The hemodynamics of the observation group was more stable than that of the control group, and the difference was statistically significant(P 0.05). Conclusions The atomization inhalation of 2% lidocaine 4ml and 0.5% dexamethasone mixture before operation as an important preventive nursing intervention can reduce the hemodynamic fluctuation and improve the postoperative comfort.
