Background:
Clinical practice in patients at risk of pulmonary aspiration varies widely. However, data on actual management, decision-driving factors and controversial issues remain elusive.
Objective:
We aimed to comprehensively review the management of patients at risk of pulmonary aspiration and identify controversies among anaesthesia professionals.
Design:
National interprofessional survey.
Setting:
All anaesthesia departments in Switzerland.
Participants:
The survey was distributed electronically to all members of the Swiss Society of Anaesthesiology and Perioperative Medicine, members of the Swiss Interest Group for Anaesthesia Nursing and all department heads in Switzerland.
Intervention:
None.
Main Outcome Measures:
Consensus and controversies in clinical practice and management of patients at risk of pulmonary aspiration.
Results:
A total of 684 respondents were included in the final analysis (59 department heads, 366 consultants, 99 registrars, 160 nurse anaesthetists). The response rate from physicians was 47%. Consensus (>80% agreement or disagreement) was reached on 9/12 (75%) questions regarding preparation for rapid sequence induction (RSI), 6/13 (46%) regarding RSI practice and 3/8 (38%) regarding management of aspiration incidents. Major controversies included high-flow pre-oxygenation (55% agreement), the validity of modified RSI in adults (52% agreement), the primary use of video-laryngoscope (76% agreement) and management of apparent regurgitation. Subjective factors such as clinical presentation were considered more important than objective factors such as medical history, comorbidities or gastric ultrasound.
Conclusion:
Across a wide range of experience and professional groups, we found a strong consensus on the indication and performance of 'traditional' RSI. However, clinical decision-making still relies heavily on subjective impressions, while newer risk stratification and management techniques remain controversial.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
