Abstract
Mechanical controlled ventilation is a standard intraoperative procedure during general anesthesia. The aim of this retrospective study was to present our experience of selecting the mode of mechanical controlled ventilation during different surgical procedures. Final analysis included 290 surgical patients in general anesthesia or a combination of general and regional anesthesia at the Sveti Duh University Hospital in one-month period during 2016. Random method for a representative sample was used to select the patients anaesthetized during December 2016. Volume controlled ventilation (204 patients, 70.3%) was the most frequently used mode of controlled intraoperative ventilation. Pressure
controlled ventilation was used in 84 (29.0%) patients. The combination of volume- and pressure-controlled ventilation and manually controlled ventilation were used in one case (0.3%) each. The median of tidal volume during volume controlled ventilation was 525 mL (500-575 mL, interquartile range), with the median of breathing rate per minute 12 (interquartile range, 12-12). The median inspiratory pressure during pressure controlled ventilation was 14 cm H2O (11-16 cm H2O,
interquartile range), with the median of breathing rate per minute 12 (12-13, interquartile range). During volume controlled ventilation, tidal volumes were adjusted in 37 (18.1%) and the rates in 75 (36.8%) cases. During pressure controlled ventilation, the inspiratory pressure parameters were adjusted in 30 (35.7%) and the rates in 24 (28.6%) cases. Adjustment of the breathing rate parameter was signifi cantly more frequent in volume controlled ventilation (p<0.001). The results
of this study demonstrate that during surgery under general anesthesia, we still more often use the traditional volume controlled ventilation that requires more anesthesiologist’s engagement in adjusting breathing rate to reach the target intraoperative ventilation parameters.
