DESIGN OF PRECISED ANESTHESIA INJECTOR

Electronics and Instrumentation Engineering

Animal experimentation are necessary for better understanding of diseases and for developing new therapeutic strategies. With the establishment of rodent models as preferred models for the study of various diseases, the effects of anesthesia on rodents have become paramount for basic science. When using animals in vivo research, there is an ethical and legal responsibility to alleviate or at least reduce pain to an absolute minimum. The problems that arise when anaesthetizing rodents are related primarily to the small body size of these species. Their high surface area to body weight ratio makes them particularly susceptible to the development of hypothermia; intravenous drug administration is limited by the size of the superficial veins and the small & relatively inaccessible larynx makes endotracheal intubation difficult. A further consequence of the small size of these species is that the volumes of anesthesia required may be very small. With practical constraints, it is often simplest to select an inhalational anesthetic agent. In contrast to injectable anesthesia, inhaled anesthesia provides a stable and depth with less cardio respiratory influence, as induction can be achieved smoothly and rapidly in an anesthetic chamber and also using a face mask with anesthesia maintained breathing system. This project deals with the methodologies for delivering anesthesia through inhalation method using Arduino unit.
