Abstract


Background: Pulmonary aspiration of gastric contents leading to acid aspiration syndrome (AAS)
is a well recognized risk factor during general anaesthesia (GA) for Caesarean section (CS). The
cross sectional observational study was conducted during July 2008 to October 2008 at
Department of Anaesthesiology and Intensive Care, Liaquat University of Medical & Health
Sciences Jamshoro, Sindh, Pakistan. The objective was to assess anaesthetic practice patterns and
measures to prevent aspiration of acid gastric contents in full term pregnant women undergoing
anaesthesia for Caesarean section. Methods: A structured questionnaire regarding practice of
anaesthesia for Caesarean section was distributed among anaesthetists working and practicing at
Hyderabad. Results from the completed questionnaires were transferred to a Microsoft Excel
spreadsheet and the responses represented as percentages. Results: General anaesthesia was
preferred by 75.4% anaesthetists for caesarean section, 83.6% anaesthetists used rapid sequence
induction with cricoid pressure during general anaesthesia, 29.5% respondents restricted clear
fluids for 2–3 hours. Antacids were used by 90% of the anaesthetists, while about 50%
anaesthetists performed extubation when patients were fully awake. Conclusion: Recommended
practice patterns and measures to prevent aspiration of acid gastric contents during anaesthesia for
caesarean section are not observed by most of the anaesthetists working at Hyderabad.
