ORAL SEDATION (click here to learn more)

Oral Sedation is best suited to manage mild to moderate nervousness. It is our most basic form of sedation. It requires the patient to arrive approximately 1 hour prior to their exam or procedure time. The patient drinks sedative syrup to help them relax during their procedure or exam. The sedative usually takes effect in approximately 30 minutes and can last for several hours once it has been taken. There is usually no recovery time involved in this type of sedation.

CONSCIOUS SEDATION (click here to learn more)

IV Sedation is a excellent way to managing extreme forms of Claustrophobia and moderate pain. IV or “conscious sedation” is an altered state of consciousness that is achieved when a combination of sedative type drugs are given as an intravenous injection by an experienced Registered Nurse. This mode is a moderate level of sedation in which the patient may experience a wide variety of effects. Some patients fall asleep while others may appear to be more awake, however all patients are able to respond verbal stimuli, light touch, and able to follow simple directions. Most patients experience profound amnesia effects and do not remember their particular procedure or exam. The recovery time for this mode of sedation may range from a few minutes to a couple of hours.

GENERAL ANESTHESIA (click here to learn more)

 Anesthesia is most often used in extreme pain cases, or when exams are exceedingly long or sensitive to motion. General anesthesia is a state of total unconsciousness, which is induced and maintained by an Anesthesiologist using IV and Inhalation (gas) medications. This mode is a deep level of sedation in which the patient is completely unaware of any external stimuli, and requires some sort of device to keep their airway open and protected while on a breathing machine. This is the same type of sedation that is used in surgeries. The recovery time for this mode of sedation may range from 30 minutes to a couple of hours.

Note that all sedation patients must have a designated driver that must sign our discharge and release form prior to the sedation process.
