Cardiorespiratory and blood gas alterations during laparoscopic surgery for intra-uterine artificial insemination in dogs

Cardiorespiratory and blood gas alterations were evaluated in 6 healthy dogs that underwent a laparoscopic procedure using isoflurane anesthesia and carbon dioxide (CO2) pneumoperitoneum for 30 min. Heart rate, respiratory rate, body temperature, venous blood pH, partial pressure of CO2 and oxygen, oxygen saturation, total carbon dioxide (TCO2) and bicarbonate were monitored. Significant alterations were hypercapnia, hypoventilation, and respiratory acidosis.
