[Sedation as a Part of Monitored Anesthesia Care (MAC) and Its Introduction to Japanese Clinical Practice].

To relieve or eliminate distress caused by invasive medical procedures, sedation is often used in routine clinical practice. Monitored anesthesia care (MAC) is needed in patients who receive increased doses of sedatives and/or analgesics, which may suppress the respiratory, cardiac, and/or vascular systems. Deep sedation, in particular, suppreses the nomal protective reflexes. It requires careful monitoring and intervention for patients. In Japan, sedation is performed in a large number of cases. It is unreasonable that only anesthesiologists administer MAC. In fact, sedation is often performed by non-anesthesiologists. In these circumstances, education and training for non-anesthesiologists are important
