Introduction
Laparoscopic ovariectomy of bitches has gained worldwide acceptance. However, the conventional insufflation method uses cold CO2 which can be associated with increased heat loss. The objective of this study was to compare the temperature of bitches submitted to laparoscopic ovariectomy insufflated with cold or heated CO2.
Materials and Methods
After approval of the institutional ethical committee, and under informed client consent, 15 bitches were submitted to laparoscopic ovariectomy with three portals. Animals were randomly distributed into groups: C – insufflated with cold CO2; or H – insufflated with 36.5°C heated CO2. Body weight, anesthetic time, surgical time, insufflation time, initial and final esophageal temperature, and temperature loss were compared by Student`s-t-test. Pearson`s test was used to verify correlation among the studied parameters. Differences was considered statistically significant when p<0.05.
Results
All animals completed the study and recovery well from the surgeries. The groups had similar values for (p>0.05) body weight, initial temperature, and anesthetic, surgical and insufflation times. The final temperature of group H was 1.02 °C higher than group C (p=0.034), and temperature loss of group H was lower than group C (p=0.023). In group C, significative correlations were observed between temperature loss and anesthetic time (p=0.002), surgical time (p<0.001), and insufflation time (p=0.01). For group H, there were no significative correlations amongst these parameters.
Discussion/Conclusion
The use of heated CO2 insufflation helps to prevent temperature loss during laparoscopic ovariectomy in bitches.
