Pulmonary aspiration during anesthesia is a serious risk. Techniques like tracheal intubation with muscle relaxants and cricoid pressure have been developed to mitigate this danger.
Area of Science:
- Anesthesiology
- Patient Safety
Background:
- Pulmonary aspiration of gastric contents poses significant risks during anesthesia.
- Mendelson's 1946 publication highlighted the morbidity and mortality associated with aspiration.
- Gastric regurgitation during anesthesia remains a critical concern for patient safety.
Purpose of the Study:
- To review the historical context and advancements in preventing pulmonary aspiration during anesthesia.
- To highlight key developments in anesthetic practice aimed at reducing aspiration risks.
Main Methods:
- Historical review of anesthetic practices and publications.
- Examination of the introduction and impact of pharmacological agents and physical techniques.
Main Results:
- The introduction of suxamethonium enabled rapid tracheal intubation under muscle relaxation.
- Sellick's description of cricoid pressure provided a method to prevent gastric regurgitation.
Conclusions:
- Significant progress has been made in managing the risks of pulmonary aspiration during anesthesia.
- Key innovations like muscle relaxants and cricoid pressure have improved patient safety.
