Clinical effect of different oxygen supply methods during anesthetics inhalation for bronchoscopy examination

Abstract

Objective To compare the clinical efficacy of different oxygen supply methods during anesthetics inhalation for bronchoscopy examination. Methods Totals of 216 patients who received bronchoscopy examination were randomly divided into two groups, with 108 cases in each. Low flow oxygen inhalation (3 L/min) with nasal canula was performed in the observation group, low flow oxygen inhalation (3 L/min) through mouth device was carried out in control group during the process of anesthetics inhalation. SpO2,pulse, comfort degree and satisfaction with anesthesia were recorded and compared between the two groups. Results At the time of 5, 10, 20, 25, 30 minutes after anesthetics inhalation, SpO2 of the observation group were (93±1)%, (95±1)%, (94±2)%, (94±1)% and (95±1)%, which were significantly higher than those in the control group (t=10.482, 12.747, 13.044, 13.301, 13.763, respectively; P<0.05). At the time of 5, 10, 20, 25, 30 minutes after anesthetics inhalation, the pulse of the observation group were (90±1), (91±2), (91±2), (92±1) and (91±2), which were significantly lower than those in the control group (t=7.867, 9.151, 10.207, 11.701, 11.063, respectively; P<0.05). Conclusions Oxygen inhalation through mouth device during anesthetics inhalation can maintain SpO2 and pulse of patients, increase the comfort degree and satisfaction with anesthesia, relief the pain of patient, and make the bronchoscopy examination more smoothly, so it should be recommended in clinical practice.
