Abstract
BACKGROUND
Fibrobronchoscopy is a common adjunct tool that requires anesthesia and is widely used in the diagnosis and treatment of various respiratory diseases. However, current anesthesia methods, such as spray, nebulized inhalation, and cricothyroid membrane puncture, have their own advantages and disadvantages. Recently, studies have shown that bronchoscopic direct-view glottis anesthesia is a simple and inexpensive method that shortens the examination time and provides excellent anesthetic results.
AIM
To evaluate the effectiveness of bronchoscopic direct vision glottis anesthesia for bronchoscopy.
METHODS
The study included 100 patients who underwent bronchoscopy during thoracic surgery. A random number table method was used to divide the patients into control and observation groups (50 patients each). The control and observation groups were anesthetized using the nebulized inhalation and bronchoscopic direct vision glottis method, respectively. Hemodynamic indices [systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and oxygen saturation (SpO2) before (T1), 5 min after anesthesia (T2), and at the end of the operation (T3)] serum stress hormone indices [norepinephrine (NE), epinephrine (E), adrenocorticotropic hormone (ACTH), and cortisol (Cor) before and after treatment] were compared between the 2 groups. Adverse effects were also compared between the two groups.
RESULTS
At T2 and T3, SBP, DBP, and HR were lower in the observation group than the control group, whereas SpO2 was higher than the control group [(119.05 ± 8.01) mmHg vs (127.05 ± 7.83) mmHg, (119.35 ± 6.66) mmHg vs (128.39 ± 6.56) mmHg, (84.68 ± 6.04) mmHg vs (92.42 ± 5.57) mmHg, (84.53 ± 4.97) mmHg compared to (92.57 ± 6.02) mmHg, (74.25 ± 5.18) beats/min compared to (88.32 ± 5.72) beats/min, (74.38 ± 5.31) beats/min compared to (88.42 ± 5.69) beats/min, (97.36 ± 2.21)% vs (94.35 ± 2.16)%, (97.42 ± 2.36)% vs (94.38 ± 2.69%], with statistically significant differences (all P < 0.05). After treatment, NE, E, ACTH, and Cor were significantly higher in both groups than before treatment, but were lower in the observation group than in the control group [(68.25 ± 8.87) ng/mL vs (93.35 ± 14.00) ng/mL, (53.59 ± 5.89) ng/mL vs (82.32 ± 10.70) ng/mL, (14.32 ± 1.58) pg/mL vs (20.35 ± 3.05) pg/mL, (227.35 ± 25.01) nmol/L vs (322.28 ± 45.12) nmol/L], with statistically significant differences (all P < 0.05). The incidence of adverse reactions was higher in the control group than in the observation group [12.00% (12/50) vs 6.00% (3/50)] (P < 0.05).
CONCLUSION
The use of bronchoscopic direct vision glottis anesthesia method for bronchoscopy patients is beneficial for stabilizing hemodynamic indices during bronchoscopy and reducing the level of patient stress, with good safety and practicality.
