Cricoid pressure in emergency rapid sequence induction.
By using the thumb and forefinger, the cricoid pressure will effectively close the esophagus until the cuffed endotracheal tube is established in the patient's airway.
It is more difficult to determine accurate landmarks on a thick and obese neck, and misapplied cricoid pressure may permit gastric insufflation and regurgitation and compromise laryngoscopy and intubation.
Following pre-oxygenation for five minutes, rapid sequence induction with cricoid pressure was performed using propofol 180 mg and suxamethonium 160 mg.
A 3-person trauma team perform intubation, routinely applying cricoid pressure to prevent gastro-oesophageal reflux and aspiration, and manual in-line cervical stabilisation is required throughout the intubation procedure since protective devices are removed routinely.
During ventilation, cricoid pressure should be initiated if not done already, and should only be released once the patient is correctly intubated and the tube cuff has been inflated.
Traditional management of general anaesthesia for caesarean section focuses on rapid attainment of adequate depth of anaesthesia, with provision of cricoid pressure and endotracheal intubation.
