Abstract

The aim of this study is to analyze body temperature, using the infrared thermography technique, in sheep submitted to laparoscopy using dorsal decubitus, trendelenburg and different intra-abdominal pressures. Ten animals will be used, in previous fasting. They will undergo anesthesia and then positioned in supine position, and later in 25º trendelenburg. For the first group - control group (GC, n = 10), the animals will not have their abdomens inflated with CO2. In the second group (G6, n = 10), animals will be submitted to moderate intra-abdominal pressure with 6 mmHg. The sheep of the third group (G12, n = 10) will be inflated and the intra-abdominal pressure will be maintained at 12 mmHg. The body surface temperature will be measured in all animals using the infrared thermography technique. Measurements will be made on the ocular surface, the head and the distal portion of the thoracic and pelvic limbs. The thermographic images of the whole body of the animals will be obtained at 1 meter of distance, from all the members. Data will be collected for 60 minutes, every 15 minutes apart. All data will be submitted to normality test and expressed in means ± standard deviation. Data will be compared among different regions of the body and the different moments through analysis of variance using ANOVA with Tukey's post-test for parametric data and Kruskal-Wallis for non-parametric data (P <0.05). Data of intra-abdominal temperature and pressure will be correlated by calculation of Pearson's correlation coefficient. For all analyzes the statistical program Bio Statis 5.0® will be used.
