Background: the maintenance of oxygenation is a frequent problem in patients who undergo a laparoscopic cholecystectomy. There are not specific guides for applying the modes of ventilation in this type of surgery. Objective: to compare two modes of ventilation, volume-controlled ventilation and pressure-controlled ventilation in patients who undergo a laparoscopic cholecystectomy. Methods: an analytical, longitudinal study was conducted. The sample was composed of 18 patients of ASA physical status I and II, scheduled for a laparoscopic cholecystectomy in Dr Octavio de la Concepción y de la Pedraja Military Teaching Hospital, Camaguey. At first, all the patients received volume-controlled ventilation. Twenty minutes later, when the pneumoperitoneum was administered, all of them received pressure-controlled ventilation. The studied variables were O₂ saturation, peak pressure, plateau pressure, respiration rate and hemodynamic parameters. Results: there was not statistical significance regarding the peak pressure. Plateau pressure presented significant differences. Respiration rate increased more with pressure-controlled ventilation than with volume-controlled ventilation, without statistical significance. Oxygenation had the same values in both modes of ventilation. The hemodynamic parameters were similar, showing more dispersion with volume-controlled ventilation. Heart rate was similar in both modes of ventilation. There was not statistical significance regarding the mean arterial pressure. Conclusion: there was difference between both modes of ventilation only regarding the plateau pressure.
