The original purpose of anesthesiology is control of excessive biological responses induced by a variety of stresses and protection of patients from stress-induced complications not just simple as anesthesia. Clinical activity of this department is divided into anesthesia in the operation theater, critical care medicine and pain control for a variety of diseases. Our ultimate goal is elucidation of mechanism for stress responses and development of treatment and care for suppression of excessive stress responses.
Research and Education
The goal of research in this department is to elucidate mechanisms of responses induced by a variety of stresses and to develop management to control stress responses. We are analyzing actions of anesthetics and opioids from many aspects. To analyze pharmacological actions of opioids at the molecular level, we have cloned cDNAs of opioid receptors, and have analyzed intracellular signal transduction mechanisms activated by opioids. Using genetically engineered mice, we are testing the role of the opioid receptor family in the pharmacological actions of inhaled anesthetics, and have demonstrated the possible involvement of the nociceptin receptor and the κ-opioid receptor in the analgesic action of nitrous oxide.
Our current research subjects are investigating various perioperative events: the effect of anesthetic agents on malignant tumor/ central nerve system, the effect of gas-like molecules on energy metabolism, and the effect of perioperative factor (including anesthetic agents) on platelet function/ blood coagulation.
This department is responsible for instruction and clinical training of anesthesiology and critical care medicine for undergraduate and postgraduate students. Residents are trained to obtain the basic capability of life support and anesthetic care in the operation room. Doctors aiming to be board certified anesthesiologists are trained for anesthetic management of special operations, intensive care for various systemic diseases and control of pain caused by various diseases.
