HEMATOLOGICAL MONITORING IN DOGS DURING LAPAROSCOPY IN VETERINARY

Abstract

Laparoscopic surgeries in animals require pneumoperitoneum which results in changes in the alveolar ventilation and hemodynamics due to excessive pressure in the peritoneal cavity. To prevent post-laparoscopy complications it is necessary to study character of hematological changes resulting from carbon dioxide pneumoperitoneum. Objective of the study was to determine informative value of the study and details of blood gases change during laparoscopic surgery. Ten apparently healthy dogs were enrolled into the study. The blood was taken from cephalic vein of the lower arm at the beginning, at the 20th and at the 40th minute of elective ovariectomies. It was found, that gas analyzer is effective for monitoring of animal’s homeostasis during laparoscopy. Further, it was found, that carbon dioxide pneumoperitoneum at 7 mm Hg resulted in changes in cell count, electrolytic and gas composition of the vein blood (pCO2, HCO3, AnGap, tco2, Na+, k+, Cl-) which varied within physiological norm, excluding (рСО2), which increased by 12.5% (from 48 ± 1.44 mmol/L at the beginning of the surgery to 54 ± 1.44 mmol/L during the surgery) without any serious adverse effect and may be balanced with superoxygenation in spontaneous breathing.
