Comparison of Anesthetic Effect of Two Kinds of Anesthesia in Experimental Surgery of Dog

Objective To investigate the anesthetic effects of sodium pentabarbital and sodium phenobarbital in the experimental surgery of dog. Method 120 experimental dogs randomly divided into two groups were injected with 3% sodium pentabarbital in a dosage of 45 mg/kg and 5% sodium phenobarbital in a dosage of 100mg/kg through peritoneal cavity, respectively. Several anesthetic indexes were observed and compared at the same time. Result The acting span in the group of sodium pentabarbital was obviously shorter than that of the group of sodium phenobarbital (%P%<0.01), and the number of dog failed to be anesthetized in the group of sodium pentabarbital was also less than that of the group of sodium phenobarbital (%P%<0.05). Conclusion Using sodium pentabarbital injected into peritoneal cavity is a fast, effective and safety way for animal experimental anesthesia, and can provide a good anesthetic effect for experimental surgery.
