Objective:
To report our experience of the use of high frequency ventilation (HFV) in thoracoscopic surgery.
Design:
Retrospective study.
Setting:
University Hospital Rotterdam, The Netherlands.
Subjects:
31 patients (18 men and 13 women, mean age 42 years, range 26-67 years) who underwent 46 thoracoscopic procedures between January 1992 and December 1997.
Interventions:
Until October 1994 patients had conventional mechanical ventilation with a double-lumen tube. Since then HFV has been used.
Main Outcome Measures:
Duration of induction, oxygen saturation, and end-tidal carbon dioxide tension.
Results:
25 procedures were done with a double-lumen endotracheal tube for one-lung ventilation and in 21 HFV was used. Induction of anaesthesia took significantly less time in the HFV group (median 14 minutes) compared with one-lung ventilation group (median 31 minutes) (p < 0.05). There were no significant differences between the groups in either SaO2 or end-tidal CO2.
Conclusion:
HFV is both safe and simple for use in thoracoscopic surgery.
