| Abstract |
BACKGROUND
It is a routine practice that High Frequency Jet Ventilation (HFJV) is applied through a 14~16 gauge (about 12 French (Fr.)) angiocath. The 14 Fr. suction catheter which is similar to angiocath in its internal diameter is commonly available in the operating room. We evaluated the suction catheter as a carrier of HFJV in point of ventilation, oxygenation and operating field during HFJV at microlaryngeal endoscopic surgery (MES).
METHODS
Fifteen adult patients undergoing HFJV via 14 Fr.
suction catheter during MES were studied. Time-based arterial blood gas analyses were done before and after HFJV.
The movement of operating field was examined using laryngoscopic examination by surgeon and anesthesiologist.
We also evaluated complications such as abdominal distension, barotrauma and so on.
RESULTS
The mean arterial oxygen tension was maintained above 250 mmHg all the time during HFJV. The mean carbon dioxide tension was less than 51 mmHg. There were no remarkable catheter movement and complications.
CONCLUSION
The 14 Fr. suction catheter is a good replacement of angiocath. It provided good operating field, ventilation and oxygenation without complications. |
