Sedation allows patients to tolerate unpleasant procedures while maintaining adequate cardiorespiratory function and the ability to respond purposefully to verbal command. For ophthalmic surgery patient's anxiety and discomfort can be relieved during placement of a peribulbar block and during surgery by intravenous sedation. Intravenous sedation should only be administered by an anesthetist. Three different classes of drugs are used for intravenous sedation: analgesics (fentanyl and alfentanil), benzodiazepines (midazolam) and profofol, an intravenous anesthetic. Sedation may result in ventilatory, cardiovascular and neurologic complications. Excessive sedation can induce hypoventilation from central ventilatory depression or airway obstruction. Uncontrolled and unexpected movements of the head could result in major surgical complications. For the prevention of the complications related to sedation the same monitoring as for general anesthesia is essential.

D007022	Hypotension	Abnormally low BLOOD PRESSURE that can result in inadequate blood flow to the brain and other vital organs. Common symptom is DIZZINESS but greater negative impacts on the body occur when there is prolonged depravation of oxygen and nutrients.	Blood Pressure, Low,Hypotension, Vascular,Low Blood Pressure,Vascular Hypotension
D007040	Hypoventilation	A reduction in the amount of air entering the pulmonary alveoli.	Hypoventilations
D008874	Midazolam	A short-acting hypnotic-sedative drug with anxiolytic and amnestic properties. It is used in dentistry, cardiac surgery, endoscopic procedures, as preanesthetic medication, and as an adjunct to local anesthesia. The short duration and cardiorespiratory stability makes it useful in poor-risk, elderly, and cardiac patients. It is water-soluble at pH less than 4 and lipid-soluble at physiological pH.

D005283	Fentanyl	A potent narcotic analgesic, abuse of which leads to habituation or addiction. It is primarily a mu-opioid agonist. Fentanyl is also used as an adjunct to general anesthetics, and as an anesthetic for induction and maintenance.
