Ventilation strategy for endoscopic retrograde cholangiopancreatography
Endoscopic retrograde cholangiopancreatography(ERCP)is an important endoscopic tech-nology in the field of digestive endoscopy.It is mainly used to diagnose biliary diseases in the early stage,and now it has developed into the diagnosis and treatment of biliary and pancreatic diseases.Compared with the general endoscopic treatment,its operation time is longer and its anesthesia risk is greater.ERCP under seda-tion/anesthesia can enhance patients'tolerance and create better diagnosis and treatment conditions for diges-tive endoscopists,but there is also the risk of anesthesia-related hypoxemia,so airway management during op-eration is particularly important.In this paper,the ventilation strategies of ERCP patients under sedation/an-esthesia were reviewed in combination with the related research in recent years.
