Effects of oxygen supplementation in ewes subjected to laparoscopic ovum pick-up under total intravenous anesthesia

Laparoscopy procedures are useful tools to perform some assisted reproductive biotechnologies in ewes, it requi-res general anesthesia and manoeuvres that might result alteration of the cardiopulmonary function. For this reason, study aimed investigate effects oxygen supplementation as a therapeutic measure mitigate these alterations ewes submitted laparoscopic ovum pick-up (LOPU) under total intravenous (TIVA). Twenty-four healthy adult were two LOPUs with 21 days interval, ketamine-midazolam anesthesia, receiving each experimental random order, treatment (OT) 50 mL/kg/min via endotracheal tube control (CT) not receive any inhalation treatment. Heart rate (HR), respiratory (fR), peripheral saturation (SpO2), mean arterial pressure (MAP), rectal temperature (RT), end-tidal CO2 concentration (EtCO2) recovery time evaluated during LOPU, blood gases electrolytes after induction at end LOPU. Variables compared between groups moments using ANOVA. MAP, SpO2, PaO2, SaO2 pH higher OT, while EtCO2, PaCO2, loss lower. These results allow conclude oxy-gen LOPU TIVA provides benefits order physiological alterations.
