Effects of propofol and ketamine anesthesia on reflexes and local temperature changes determined in different regions by infrared thermographic imaging in rats

Abstract

Objective: Infrared thermography (IRT) stand out with it’s important advantages such as reducing the risk of contamination, providing fast results, being easy and safe. This study was aimed to investigate IRT temperature measurements in rats that were administered two different anesthetics in terms of anesthetics and localizations. Materials and Methods: Twenty Wistar rats were used in the study. After sedation with xylazine hydrochloride (10 mg/kg IM), the rats were divided into two groups (n=10). Group 1 was anesthetized with ketamine hydrochloride (40 mg/kg IM) and Group 2 with propofol (20 mg/kg IM). The disappearance of movements and reflexes during anesthesia and recovery were recorded. Local temperatures were recorded at certain times before, during and after anesthesia with shots including the mouth, nose, eye, ear and rectum regions by IRT. Results: During the recovery, the return times in sense, movement, and reflexes were significantly higher in Group 2 (p
