Chapter 1: Introduction
Moderate sedation is the technique of providing medication to relieve anxiety and discomfort during medical procedures. Unlike general anesthesia where patients are completely unconscious, patients receiving moderate sedation are semi-conscious and should be comfortable during the procedure. Moderate sedation is also referred to as “conscious sedation” or "procedural sedation."
Moderate sedation is performed by administering medications through an intravenous catheter (IV) to provide relaxation and to minimize discomfort to the patient while the procedure is performed. The patient may feel drowsy or may even sleep through most of the procedure. At all times the patient should be easily awakened when spoken to or touched. The patient may not remember the procedure; however, it is important to remember that the patient can hear and often will remember conversations heard during the procedure. It is important to remain professional at all times. Although not completely asleep, the patient should be medically monitored before, during, and after the procedure. The nurse should closely monitor the patient’s heart rate, heart rhythm, blood pressure, and oxygen levels to ensure patient safety. The patient should wear a nasal cannula through which oxygen may be administered if needed, as the patient’s breathing may become slower and even more shallow than normal under moderate sedation.
After the procedure the patient should be observed for a short time, usually one hour, as the sedation medication wears off. There are generally no significant after-effects of moderate sedation. However, the patient’s judgment, reaction time, and short-term memory may be impaired for the next 24 hours. Thus the health care provider should advise that patients do not drive, operate heavy equipment, or make any important decisions during this time period. Since the patient should not be permitted to drive, they must bring a responsible adult over the age of 18 to accompany them home.
