ABSTRACT

Background: Mechanical ventilation strategies are used to prevent lung damage, optimizing gas exchange. Recently, has been described that mechanical support limited by volume and pressure reduces lung overdistention. The aim of our study was to compare pressure control and volume control modalities in patients underwent to different laparoscopic approaches. Methods: With local ethics committee approval and written informed consent, 40 patients (Class I/II ASA) undergoing elective laparoscopic surgery were included in the study. The patients were fasted from midnight before the day of surgery . Anesthesia was induce with phentanyl (2 µg/kg), propofol (2 mg/kg) and atracurium (150 µg/kg). Endotracheal intubation was performed after complete relaxation evaluated with train of four (TOF). Anesthesia was mantained with sevoflurane (1 MAC). Patients were randomized to receive PCV or VCV. Results: Haemodynamic parameters were similar in both groups during the different periods of time recorded. Systolic, diastolic and mean pressure were similar. During pneumoperitoneum SpO₂2 remained similar for both groups (p 0.368). Conclusion: In summary we conclude that PCV and VCV are both well tolerated ventilation modalities for patients submitted to laparoscopic surgery.
