Anesthesia Induction Sequence

A typical general anesthesia induction sequence for an adult is as follows: after establishing intravenous access and placement of standard American Society of Anesthesiologists (1) monitors, a patient is preoxygenated with 100% oxygen. An induction dose of intravenous medications such as propofol, an opioid, and a muscle relaxant are administered (see JPEG 1, on the Companion CD and description at end of chapter). After the patient is rendered unconscious and anesthetized, direct laryngoscopy is performed, and the trachea intubated with an endotracheal tube. After confirmation of endotracheal intubation, the patient is placed on an anesthesia ventilator and next ventilated with a combination of anesthetic gases, air, and oxygen (see JPEG 2, on the Companion CD and description at end of chapter). Note, if a total intravenous anesthetic technique (such as propofol and opioid infusion) is chosen, anesthetic gases are not administered.

The cardiovascular depressant effects of most anesthetics typically become evident during and immediately following induction. Maintaining cardiovascular stability requires careful titration of medications, knowledge of clinical and basic

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
