          A textbook of Anesthesia for technicians is designed to suit the training requirements of anesthesia nurses/technicians. The book is currently in its second reprint and is published by Paras Medical Publishers.

Role of Anesthesia Nurse/Technician
nurse anesth2.jpeg

            Anesthesia nurse/technician is a specially trained person who can assist the anesthesiologist in key life saving procedures/skills in addition to getting the operating room ready for the surgery and play an important part throughout the working of the operating room. He/she can also play an important role in intensive care units and emergency rooms. 

            The concept of nurse anesthetist/CRNA has been well established in certain institutions, where in addition to monitoring patients who are receiving and later recovering from anesthesia, CRNAs are also entitled to administer anesthetics in specified domains.
