High freqency jec ventilation (HFJV) via cricothyroid membrane puncture contols
frequency of ventilation as 20-200/min and persuits adequate gas exchange. HFJV was known
to have advantages such as improvement of PaO2, lesser barotrauma, stable hemodynamic
effects, good operative field and lesser movement of head.
The purpose of this study was to clarify the advantages of HFJV in cases of microlaryngeal
surgery which operating time was expected even within 30 minutes.
Twenty-eight patients were divided two groups; 1) control group: general endotracheal
intubation anesthesia. 2) experimental group: HFJV via cricothyroid membrane puncture with
intravenous enesthesia, frequency 40/min, I/E ratio 40%, driving pressure 40 psi.
We analyzed blood pressure, arterial blood gas, score of general condition and recovery time
after operation.
In conclusion, HFJV via cricothyroid membrane puncture had a good score of general
condition and rapid recovery of consciousness, although some accumulation of PCO2 and
elevation of blood pressure.
