Mechanisms of regurgitation and its prevention with cricoid pressure

The effect of mechanically‐induced cricoid force on lower oesophageal sphincter pressure in anaesthetised patients

“…However, the influence of newer pharmacological agents and increased use of regional anaesthesia may well have contributed to this [2]. Over the same period, there has been an increase in the number of deaths from failed airway management [25]. A survey of failed intubation in a teaching maternity unit reported an increase in incidence from 1 : 300 in 1984 to 1 : 250 in 1994 [26].…”

Life-saving or ineffective? An observational study of the use of cricoid pressure and maternal outcome in an African setting

“…The mechanism allowing aspiration of gastric contents is a four-stage process: 12 1. A full stomach, either from eating or from delayed gastric emptying, due to stress or systemic opioid administration.…”

Survey of Anesthesic Risk Factors during Obstetric Emergency at the Peace Hospital in Ziguinchor

“…This rate is explained by the evolution of the practice of spinal anesthesia but mainly because the risk of complications is less, but also because the early referring of patients in emergency via a collaboration between anesthetists, gynecologists and other maternity wards. The current trend is to encourage loco-regional techniques in cesarean sections to avoid risks associated with anatomical changes in the pregnant woman that are responsible for difficult ventilation and intubation, oesophageal intubation and inhalation of gastric contents [13,14]. Halothane that is no longer found in many countries is the halogen used in our series.…”
