Assessment Of Pre-procedure Versus Spray-as-you-go Airway Anesthesia Protocols In Bronchoscopy

Background and objectives

Fiberoptic bronchoscopy involves various topical airway anesthesia protocols, which tin effect diligent comfort, procedural ease, and wide outcomes. This study aimed to comparison pre-procedure lignocaine spray (PPL) and spray-as-you-go (SAYG) airway anesthesia successful position of diligent discomfort and usability comfortableness during fiberoptic bronchoscopy.

Methods

A single-blind randomized controlled proceedings was conducted astatine nan Pulmonology Department of Shaikh Zayed Hospital, Lahore, Pakistan, from March 2021 to March 2022. Fifty participants were randomly assigned to 2 groups (n = 25 each). Standard procedural sedation pinch midazolam and 2 mL of 4% lignocaine spray successful nan oropharynx was utilized to suppress nan gag reflex. Additionally, 2% lignocaine spray was administered during nan process according to assemblage weight (3 mg/kg) via oral scope insertion. Cough severity, symptom perception, and usability comfortableness were assessed utilizing nan Visual Analogue Scale, Faces Pain Rating Scale, and a 4-point Likert scale, respectively.

Results

Demographic characteristics were comparable betwixt nan groups, pinch a insignificant property quality (PPL: 53.25 years vs. SAYG: 50.88 years, p = 0.017). No important differences were observed successful symptom perception, cough scores, aliases process long betwixt nan PPL and SAYG groups. Operator comfortableness scores showed a inclination favoring PPL (60% rated arsenic "comfortable" aliases "very comfortable" vs. 28% successful SAYG), though nan quality was not statistically important (p = 0.108).

Conclusions

This study concludes that PPL spray and SAYG protocols are comparable successful efficacy for FOB, pinch nary important differences successful patient-reported pain, discomfort, coughing, aliases process duration. Operator comfortableness was somewhat higher pinch nan pre-procedural protocol, though this quality did not scope statistical significance. Nonetheless, moreover a insignificant betterment successful usability comfortableness could perchance lead to reduced fatigue, improved focus, and enhanced performance. Further studies pinch larger cohorts are warranted to validate these observations.
