“…Studies that find no difference in oxygenation between PCV and VCV in laparoscopic surgery may be due to differences in patient groups, surgical methods, surgical position, or type of surgery. 13,19,21,22 In patients who had undergone laparoscopic cholecystectomy, peak and plateau airway pressures were lower and compliance was higher in PCV mode than in VCV mode, according to the findings of this study. An increase in postoperative oxygenation was observed in the PCV mode.…”

“…9,10 In studies comparing different mechanical ventilation modes used to prevent and correct these physiopathological changes, different results were observed. [11][12][13][14][15][16][17][18][19][20][21] In our study, we compared the changes induced by VCV and PCV modes in hemodynamics (HR, SAP, DAP, MAP), respiration (airway pressures, gas exchange parameters) and metabolism (acid-base balance) in patients undergoing laparoscopic cholecystectomy.…”

“…Lower airway pressures were observed in similar research of patients undergoing laparoscopic surgery in the PCV mode. 11,16,19,20 It has also been highlighted that the airway pressure was higher, especially in patients with high BMI. 16,17 The rise in mean airway pressure was caused by the initial rapid flow leading to early alveolar inflation, according to studies that found the P peak value to be lower in PCV mode and the P mean value to be higher.…”

Background: This study aimed to compare the changes induced by VCV and PCV modes in hemodynamics, respiration (airway pressures, gas exchange parameters) and metabolism (acid-base balance) in patients undergoing laparoscopic cholecystectomy.Methods: Patients were divided into two randomised groups as volume-controlled ventilation (VCV) group (VC) and pressure-controlled ventilation (PCV) group (PC). The following parameters were recorded at 3 different time points: T1: in supine position 10 minutes after induction of anaesthesia, T2: 15 minutes after CO2 insufflation in inverted Trendelenburg position (head 30 degrees up), T3: 10 minutes after CO2 desufflation. HR, SpO2, SAP (systolic arterial pressure), DAP (diastolic arterial pressure), MAP (mean arterial pressure), PetCO2 (end-tidal carbon dioxide pressure), Ppeak, Pplateau, Pmean, Vt (tidal volume) and compliance with the available data, the cases in both groups Vd, Vd/Vt ratios and P(A-a)O2 were calculated. Arterial blood gas parameters (pH, PaO2, PaCO2, SaO2, P(a-et)CO2) values were recorded.Results: It was found that Ppeak and Pplateau values were significantly higher in the VC group (p<0.05). It was found that compliance was significantly higher in the PC group (p<0.05) (p<0.01). In the postoperative period, it was found that PaO2 values were significantly higher in the PC group compared to the VC group (p<0.05). It was found that the P(A-a)O2 values of the PC group were significantly higher than those of the VC group during the desufflation phase (p<0.05).Conclusions: We think that PCV mode can be a good alternative for the prevention and correction of physiopathological changes due to laparoscopic surgery.

“…In some previous studies, the most critical advantage of PCV ventilation has been the peak inspiratory pressure reduction and, consequently, the lower probability of barotrauma (21,22). Dion et al examined 20 patients undergoing laparoscopic bariatric surgery and used VCV, PCV, and pressure control-volume guaranteed (PCV-VG) modes; they found that PCV and PCV-VG caused less PIP compared to VCV (23).…”

Background: The number of patients with obesity undergoing various surgeries is increasing annually, and ventilation problems are highly prevalent in these patients. Objectives: We aimed to evaluate ventilation effectiveness with pressure-controlled (PC) and volume-controlled (VC) ventilation modes during laparoscopic bariatric surgery. Methods: In this open-label randomized crossover clinical trial, 40 adult patients with morbid obesity candidates for laparoscopic bariatric surgery were assigned to VC-PC or PC-VC groups. Each patient received both ventilation modes sequentially for 15 min during laparoscopic surgery in a random sequence. Every 5 min, exhaled tidal volume, peak and mean airway pressure, oxygen saturation, heart rate, mean arterial pressure, and end-tidal CO2 were recorded. Blood gas analysis was done at the end of 15 min. Dynamic compliance, PaO2/FiO2 ratio, P (A-a) O2 gradient, respiratory dead space, and PaCO2-ETCO2 gradient were calculated according to the obtained results. Results: The study included 40 patients with a mean age of 35.13 ± 9.06 years. There were no significant differences in peak and mean airway pressure, dynamic compliance, and hemodynamic parameters (P > 0.05). There was no significant difference between the two ventilation modes in pH, PaCO2, PaO2, PaO2/FIO2, dead space volume, and D (A-a) O2 at different time intervals (P > 0.05). Conclusions: If low tidal volumes are used during adult laparoscopic bariatric surgery, mechanical ventilation with PC mode is not superior to VC mode.
