Did you know that each year, approximately 313 million surgeries are performed worldwide? That’s huge, isn’t it? As the number of surgical procedures increases, more facilities become equipped to perform them. While not every surgical procedure requires it, the prevalence of inhalational anesthesia administration has grown. While there are 5 inhalational agents, and one inhalational anesthetic gas (nitrous oxide), inhalational anesthetics such as, halothane, and enflurane are less commonly used.
