Abstract :

Objectives To compare the parameters using VCV and PCV modes of ventilation with the use of PLMA as an airway device, in adult patients undergoing laparoscopic cholecystectomy: Methodology The patients were randomly allocated to one of the two study groups (VCV and PCV groups PLMA device will be prepared for insertion with cuff deflated . The patients will be allocated to one of following groups: Group: I (n=30) those in which VCV mode of ventilation will be used Group: II (n= 30) those in which PCV mode of ventilationwill be used Results There were no significant differences in patient characteristics and co–morbidity in the two groups. Mean pH, PaO2, SaO2, and the PaO2/FIO2 ratio were higher in the PCV group, whereas PaCO2 and the E′CO2–PaCO2 gradient were lower (all P<0.05). Ventilation variables, including plateau and mean airway pressures, anaesthesia–related variables, and postoperative cardiovascular variables, blood gases, and morphine requirements after the operation were similar. Conclusion. PCV compared with VCV during anaesthesia for laparoscopic cholecystectomy improves gas exchanges without increasing ventilation pressures or causing any haemodynamic side–effects. . In addition, using PCV routinely requires a good knowledge of its operating principles and a careful setting of the alarm limits .
