简介
Objective
To compare the effects of pressure controlled ventilation (PCV) with volume‐controlled ventilation (VCV) on lung compliance, gas exchange, and hemodynamics in isoflurane‐anesthetized dogs.
Design
Prospective randomized study.
Setting
Veterinary teaching hospital.
Animals
Forty client‐owned bitches undergoing elective ovariohysterectomy.
Interventions
Dogs were randomly assigned to be ventilated with 100% oxygen using PCV (n = 20) or VCV (n = 20). The respiratory rate was 20/min and positive end‐expiratory pressure (PEEP) was 5 cm H2O, with a tidal volume of 10 mL/kg. Cardiac output (CO) was measured using thermodilution. Cardiopulmonary and blood gas data were obtained during spontaneous ventilation and after 30 (T30) and 60 minutes (T60) of controlled ventilation.
Measurements and Main Results
In dogs ventilated with PCV, at T30 and T60, PIP was lower (11.4 ± 1.9 and …
