Midazolam has been associated with respiratory depression and respiratory arrest, especially when used for sedation in noncritical care settings. Use only in settings that can provide for continuous monitoring of respiratory and cardiac function. The initial dose and all subsequent doses should always be titrated slowly. Midazolam injection should not be administered by rapid injection in the neonatal population as severe hypotension and seizures have been reported .
Midazolam is used to produce sleepiness or drowsiness and to relieve anxiety before surgery or certain procedures. Midazolam is also given to produce amnesia (loss of memory) so that the patient will not remember any discomfort or undesirable effects that may occur after a surgery or procedure . It is also used to produce loss of consciousness before and during surgery. Midazolam is sometimes used in patients in hospital intensive care units to cause unconsciousness. This may allow the patient to withstand the stress of being in the intensive care unit and help the patient cooperate when a machine must be used to assist with breathing.
Midazolam is given only by or under the immediate supervision of a doctor trained to use this medicine. If you will be receiving midazolam during surgery, your doctor or anesthesiologist will give you the medicine and closely follow your progress.
