Abstract

Currently, sedation anesthesia is increasingly used in many medical fields, from gastroscopy to medical imaging. The demand for sedation anesthesia is expected to increase gradually with increasing number of day surgeries and increased expectations from medical services. The demand for sedation anesthesia is considerably higher than the available pool of anesthesiologists; therefore, in a significant number of cases, sedation anesthesia is induced by non-anesthesiologists. However, there is no systematic provision of education or expertise for non-anesthesiologists in delivering sedation anesthesia. In cases of non-anesthesiologists inducing anesthesia, social controversy is often caused by medical accidents and substance abuse. In this review, I have briefly summarized what non-anesthesiologists should know about sedation anesthesia and have presented guidelines simplifying sedation anesthesia for non-anesthesia medical personnel.

Key words: Hypnotics and sedatives; Propofol; Etomidate; Dexmedetomidine; Ketamine
