A review of patients with pulmonary aspiration of gastric contents during anesthesia reported to the Departmental Quality Assurance Committee

Audits and critical incident reporting in paediatric anaesthesia: lessons from 75,331 anaesthetic

“…(22) The risk factors reported to be associated with aspiration and regurgitation in children include greater severity of disease (ASA III-V), intravenous induction and emergency procedures. (23,24) According to Kluger et al, the mortality rate following aspiration varies between 1 in 35,000 to 1 in 72,000. (22) Other sequelae such as laryngospasm, desaturation and bronchospasm can also occur.…”

The safety of deep sedation without intubation for abortion in the outpatient setting

“…Several large studies have failed to confirm pregnancy as a relevant risk factor, finding no overrepresentation of obstetrical patients among cases of aspiration [8,11,13,14]. In a review of 172,335 adults who had 215,488 general anesthetics, Warner et al found that emergent procedures and the presence of comorbidities were the most significant predictors of pulmonary aspiration; pregnancy was not an independent risk factor [13].…”

Rapid sequence induction for appendectomies: a retrospective case-review analysis

“…10 In the series of 24 cases of aspiration in children published by Warner et al, there were no cases of appendicitis. 21 Similarly, appendicitis is not part of the diagnoses listed by Sakai et al 23 (23 cases) and Neelakanta et al 24 (23 cases). Thus, aspiration in patients presenting for appendix surgery is a rare event, and it is not surprising that none were found in our study.…”
