This study explores the applicability of general anesthesia with a laryngeal mask airway in painless bronchoscopy and its impact on the sense of comfort and satisfaction. Using the random number table method, we divided 101 elderly patients with respiratory disease who underwent bronchoscopy into two groups, with one group receiving intravenous general anesthesia (IVGA) and the other group receiving laryngeal mask airway general anesthesia (LMAGA). Their vital signs, including heart rate (HR), mean arterial pressure (MAP) and oxygen saturation (SpO2), were compared and we also examined their perioperative adverse effects and assessed the sense of comfort and satisfaction. There were no significant differences in vital signs, including HR, MAP and SpO2, between the two groups before anesthesia (T0). However, at T1 and T2, the HR of patients in the LMAGA group was significantly lower than that of the IVGA group. Additionally, the MAP and SpO2 levels in the LMAGA group were significantly higher than those in the IVGA group. The LMAGA group also demonstrated significantly shorter surgical duration and faster recovery from anesthesia than the IVGA group. Furthermore, the LMAGA group exhibited a significantly lower incidence of adverse effects and a notable increase in comfort and satisfaction compared to the IVGA group. LMAGA demonstrates a significant anesthetic effect in painless bronchoscopy, effectively improving the patient’s vital signs, reducing the duration of the operation and anesthetic recovery time, lowering the occurrence of perioperative adverse reactions, and enhancing the overall sense of comfort and satisfaction.
