Airway can be secured either via preexisting tracheostomy tube, different varieties of ETT, high frequency jet ventilation (HFJV) or LMA.
Given the stable clinical situation, we decided to perform a rigid bronchoscopy to extract this foreign body under general anesthesia, using HFJV (FiO2 = 1; pressure of 2 atm; f= 150 cycles/min, and I-time of 50%), once the patient had accomplished the fasting time of 6 h.
HFJV has demonstrated its usefulness especially in neonates and pediatric patients, providing adequate gas exchange and minimizing risk of chronic respiratory diseases.
The use of HFJV was determined at the discretion of the attending anesthesiologist.
Patients receiving HFJV compared to CMV were no different in terms of age, body mass index, lower pole stones, stones size greater than 1 cm and number of stones.
Twelve patients were randomized to receive HFJV or SV The HFJV group received total intravenous anaesthesia.
The stones of patients in the SV group moved more than those of patients in the HFJV group (mean 5.4 mm vs 1.6 mm, P<0.01).
This involved the use of HFJV for the right and left lungs separately with two high-frequency jet ventilators (Mera[TM] High Frequency Jet Ventilator JP-1, Senko Medical Industrial Co, Tokyo, Japan).
HFJV during anesthesia for tracheal surgery has several advantages over cardiopulmonary bypass (2,3).
