Comparison of Lung Function in Patients After Lower Abdominal Surgery Exceeding 2hrs Under the Use of Laryngeal Mask vs. Endotracheal Tube for Airway Management
Comparison of Lung Function in Patients After Lower Abdominal Surgery Exceeding 2hrs Under the Use of Laryngeal Mask vs. Endotracheal Tube for Airway Management
We measure in this study lung function of 100 patients immediately after major lower abdominal surgery. We compare lung function, when either endotracheal intubation, or laryngeal masks are used for airway protection during surgery. The hypothesis is that the use of laryngeal masks is associated with less impairment of lung function in the immediate postoperative phase.
Inclusion Criteria - patients scheduled for elective retropubic radical prostatectomy
Exclusion Criteria:
- increased risk of aspiration due to hiatal hernia, morbid obesity, or facial malformations
