Videothermometry to evaluate metabolic activity in real time during pneumectomy in rats

Abstract Purpose: To evaluate, in rats, the open field videothermometry in real time while performing left pneumonectomy for early diagnosis of cardiopulmonary changes. Methods: Twelve non-specific pathogen-free Wistar rats were randomly allocated into two groups; pneumectomy group (GP) and sham surgery group (GS). Mean arterial pressure, videothermometry in real time, of the right lung, and histopathological analysis of the remaining lung were evaluated in all animals. Results: Videothermometry in real time allowed identification of temperature variance of right lung after pneumectomy, indicating a significant decrease in temperature during evaluation. There was a statistical difference between M0 and M1, M1 and M2 and M0 and M2 (p
