Research Interests:

Veterinary clinical anesthesia, as related to pharmacology and cardiopulmonary physiology; Pain and drugs used for its prevention and relief; Research techniques in catecholamine as they reflect response to acute and chronic pain; Clinical response to anesthesia in laboratory animals and exotic species.

My current research includes: (1) comparative study of epidural analgesia in cattle using alpha2 adrenoceptor agonists: Alpha2 agonists have been reported to induce epidural analgesia comparable to lidocaine but with less motor function interruption and longer duration. In this study we compare the epidural analgesia effects induced by alpha2 agonists (xylazine, clonidine, and detomidine) to that of lidocaine. Heart rate, respiratory rate and arterial blood pressure are monitored throughout the study period. The duration of analgesia of each drug is determined by electrical stimulus using peripheral nerve stimulator applied on the perineal area. (2) Use of medetomidine as a sedative in llamas: Medetomidine is a new alpha2 adrenoceptor agonist that has been successfully used as a sedative in dogs, cats, and a number of exotic animals. Different dosages will be used in this study to determine the clinically useful dosage for llamas.
