ABSTRACT

Objective: To know the changes on the compliance of postoperative patients supported with mechanical ventilation -volume-controlled versus pressure-controlled (PC, VC)- and its effects on the PaO2/FIO2 ratio.
Design: Case series report.
Setting: ICU of a tertiary care hospital, Mexico City.
Patients: Seven patients without pulmonary illness underwent to surgery of upper abdomen were included. Results: The mean Pip in PC was 21.7 and in VC 25 (P = 0.0059). The mean delta P in PC was 15.9 and in VC 18.8 (P = 0.0086). The mean value of Cdyn in PC was 30 and in VC 23.2 (P = 0.0088). PaO2/FIO2 ratio was respectively 210.8 in PC and 205.7 in VC (P = 0.8243).
Conclusions: Pressure-control may be the best option in the management of mechanical ventilation in patients underwent to surgery of upper abdomen.
