Pre-anesthetic presence of an injured dam influences pups' locomotor behavior during emergence from anesthesia in rats
Pre-anesthetic mother–infant interaction is an important factor for smooth emergence of pediatric anesthesia. In many mammalian species, disruptions of the mother–infant relationship cause psychological and behavioral changes. This study was to investigate whether or not pre-anesthetic presence of an injured dam has an impact on locomotor behavior of rat pups. Methods:
We used a video-tracking system to test the effects of pre-anesthetic relations between pups and their dams on pups' locomotor behavior during emergence from general anesthesia, in 40 3-week-old Sprague-Dawley male rats. Pups were divided into two groups: pups housed with a dam (n = 20) and those housed with an injured dam (n = 20). Pups were anesthetized with 1.2% halothane for 30 min. At emergence, we recorded their locomotor behavior for 15 min. Results:
Pre-anesthetic manipulation to dams significantly increased the distance traveled by pups. However, the manipulation did not cause any difference in the maximum velocity. Conclusion:
Pre-anesthetic presence of an injured dam influenced pups' locomotor behavior at emergence from anesthesia.
