Objective To observe the effects of transcutaneous electrical acupoint stimulation (TEAS) combined with laryngeal mask general anesthesia on the stress response and quality of early postoperative recovery in patients undergoing fiberoptic bronchoscopy.

Methods Eighty patients were selected to undergo painless fiberoptic bronchoscopy, and were divided into a control group (laryngeal mask general anesthesia group) and an observation group (TEAS combined with laryngeal mask general anesthesia group) by using a randomized numerical table method, with 40 patients in each group. In the observation group, TEAS was performed on bilateral Hegu, Neiguan, Leshu and Tiantu acupoints 30 min before induction of anesthesia, and the laryngeal mask was continuously stimulated until the laryngeal mask was withdrawn at the end of the operation; in the control group, electrodes were pasted on the same acupoints and the same time points, but no stimulation was performed. The changes in the values of mean arterial pressure (MAP) and heart rate (HR) of the patients were recorded 30 min before the induction of anesthesia (T₁), before the induction of anesthesia (T₂), at the moment of fiberscope entry (T₃), and at the time of withdrawal of the fiberscope (T₄). The time of anesthesia, time of surgery, and time of awakening were recorded. The total dose of anesthetic drugs remazolam and remifentanil used was recorded. Changes in preoperative and postoperative stress indicators cortisol, C-reactive protein, and angiotensin Ⅱ were recorded. Quality of recovery scale scores (QoR-15) were recorded 1 d preoperatively (T₀) and 1 d postoperatively (T₅). Perioperative choking, respiratory depression, cachexia were recorded cardiac vomiting, vertigo and other adverse reactions.

Results Compared with the control group, the recovery time of the observation group was significantly shortened, the use of remimazolam and remifentanil was significantly reduced, the incidence of adverse reactions was significantly reduced, the stress factor indexes of the observation group were significantly reduced (P < 0.05 to P < 0.01), and the T₂, T₃, The HR and MAP at T₄ were significantly lower than those in the control group and T1, and the postoperative QoR-15 scale score in the observation group was significantly higher than that in the control group (P < 0.05 to P < 0.01).

Conclusions TEAS combined with laryngeal mask general anesthesia applied to patients with fiberoptic bronchoscopic diagnosis and treatment has the advantages of inhibiting airway irritation stress response, maintaining intraoperative hemodynamic stability, and promoting postoperative recovery, which can improve the anesthetic safety and enhance the comfort of patients.
