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

Abstract

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.

Evaluation of Supraglottic Jet Oxygenation and Ventilation in 105 Patients During Bronchoscopy Using the Twinstream® Microprocessor-Controlled Jet Ventilator and the Wei Nasal Jet® Tube

“…The advantages of WNJ use include ease of use, fewer complications, and the potential to increase the functional residual capacity (FRC) of the lungs. WNJ has become a commonly used ventilation tool for difficult airway management, especially for patients with poor cardiopulmonary function [ 9 ]. Jet ventilation is a technique used to maintain oxygenation and ventilation.…”

“…Due to its comfort and simplicity of wearing, endoscopic face masks are more widely used in clinical practice. The Wei Nasal Jet ® (WNJ) tube is a newly invented 2-wall nasal airway for supraglottic jet oxygenation and ventilation (SJOV) and end-tidal partial pressure of carbon dioxide (CO 2 ) monitoring [9][10][11][12]. Its inner diameter is 5.0 mm, outer diameter is 7.5 mm, and length is 18 cm.…”
