摘要: In the United Kingdom, cricoid force is central to upper airway management in obstetric and emergency anaesthesia. A reduction oesophageal barrier pressure (OBP) these patients may increase regurgitation risk. This study investigated whether application of anaesthetised reduced lower sphincter (LOSP) consequently OBP. Anaesthesia was induced 29 using a standard protocol. An balloon catheter inserted gastric trace identified. The withdrawn incrementally readings recorded at each position before during 30 N force, with sudden rise indicating position. Oesophageal calculated as difference between LOSP pressure. Application significantly OBP without influencing (p < 0.001). use risk gastroesophageal reflux patients.
