WEI nasal jet tube during monitored anaesthesia care for removal of oesophageal foreign body for a patient with fragile cardiopulmonary function

This manuscript reports a case of foreign body removal surgery and anaesthesia of an elderly patient with a challenging airway and fragile cardiopulmonary function. WEI Nasal Jet Tube (WNJ) was used to sustain sufficient oxygenation without interfering with the gastroscopy operation. Because the device could be well tolerated by the patient, it was beneficial to maintain circulation stability as well. This case was a considerable anaesthetic challenge, as the anaesthesia depth for the patient was difficult to manage.
