The aim of this study was to evaluate the effects of CPAP in brachycephalic dogs during recovery from anaesthesia. Forty-nine dogs were anaesthetized with metha- done (0.3 mg kg 1) IM, propofol to effect IV and isoflurane in oxygen via an ET tube. After extubation dogs breathed room air for 5 minutes and an arterial blood sample was collected (T0). Thereafter a paediatric helmet was placed, and oxygen was administered throughout a venturi valve, (Staffieri et al. 2014). The CPAP group (n = 32) received 5 cm H2O CPAP, the NOCPAP group (n = 17) 0 cmH2O. After 30 minutes (T30) another arterial sample was collected. PaO2, PaCO2, SaO2, pH, PaO2/ FiO2, the P(A-a)O2 and the estimated shunt (FShunt) together with fR, and FiO2 were compared within and between groups (ANOVA). CPAP at 5 cmH2O is effective in improving oxygenation in brachycephalic dogs recovering from anaesthesia.

Abstract
The aim of this study was to evaluate the effects of CPAP in brachycephalic dogs during recovery from anaesthesia. Forty-nine dogs were anaesthetized with metha- done (0.3 mg kg 1) IM, propofol to effect IV and isoflurane in oxygen via an ET tube. After extubation dogs breathed room air for 5 minutes and an arterial blood sample was collected (T0). Thereafter a paediatric helmet was placed, and oxygen was administered throughout a venturi valve, (Staffieri et al. 2014). The CPAP group (n = 32) received 5 cm H2O CPAP, the NOCPAP group (n = 17) 0 cmH2O. After 30 minutes (T30) another arterial sample was collected. PaO2, PaCO2, SaO2, pH, PaO2/ FiO2, the P(A-a)O2 and the estimated shunt (FShunt) together with fR, and FiO2 were compared within and between groups (ANOVA). CPAP at 5 cmH2O is effective in improving oxygenation in brachycephalic dogs recovering from anaesthesia.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
