IV sedation, sometimes called conscious sedation, is a group of medications that doctors administer through a vein to block pain and help a patient relax during medical procedures, notes MedlinePlus. IV sedation usually takes effect quickly and allows the doctor to easily control the patient's sedation level, explains WebMD.
After receiving IV sedation, most patients feel drowsy, their breathing slows and their blood pressure decreases, notes MedlinePlus. Some patients fall asleep, while others stay awake and can respond to verbal commands. Patients may not remember much about the events surrounding their procedures after receiving IV sedation. Doctors generally use IV sedation for short procedures, such as dental surgeries, breast biopsies, colonoscopies, or minor foot, skin and bone fracture repair surgeries.
