Abstract:
Objective To explore the optimal dose and ways of anesthesia for creating a rat model of spastic paralysis with intermittent bilateral common carotid artery ligation. Methods 60 Wistar rats were randomly divided into groups A, B, C, D, E and F. Group A was anaesthetized with 10% chloral hydrate 5 ml/kg injected subcutaneously, while group B with 4 ml/kg subcutaneously, group C with 4 ml/kg intraperitoneally, group D with 3 ml/kg subcutaneously, group E with 3 ml/kg intraperitoneally, group F with 2 ml/kg subcutaneously. The onset and duration of anesthesia, and intraoperative and postoperative mortality were compared. Results All the rats in the group A died during anesthesia, while the group F did not achieve the depth of anesthesia, and abandoned. The onset time was (6.5±0.7) min, maintained (121.4± 3.9) min, mortality was 0 in the group B, and it was (5.5±1.1) min, (122.0±3.6) min, 30% in the group C; (9.6±0.8) min, (106.7±3.7) min, 0 in the group D, (7.4±1.2) min, (105.3±3.5) min, 20% in the group E. The overall mortality rate was 0 in the groups accepted subcutaneous injected and 25% of intraperitoneal injection. Conclusion Anesthesia with 10% chloral hydrate 4 ml/kg subcutaneous injection is optimal of lower mortality, faster onset and longer maintaining in rats for spastic paralysis model with intermittent bilateral common carotid artery ligation.
