What else can I help you with?
Why is the patient asked to make movements during a pallidotomy?
During the procedure, the patient will be asked to make various movements to assist in determining the location of the electrode.
Why is it essential that a patient stay awake during a pallidotomy?
In addition, the patient must remain awake in order to report any sensory changes during the surgery.
Who administers the local anesthetic to an eye surgery patient?
An anesthesiologist may be on hand during surgery to administer the local anesthetic.
Visual changes during a pallidotomy may be indicative of what problem?
Visual changes may indicate the probe is too close to this region.
How do they freeze the eye ball for surgery?
Freezing the eyeball for surgery typically involves the use of a local anesthetic rather than actual freezing. An ophthalmic surgeon may apply a topical anesthetic to numb the surface of the eye, or inject a local anesthetic around the eye area to reduce sensation. In some cases, cooling techniques may be used to minimize damage to surrounding tissues, but the eye itself is not frozen in the traditional sense. The goal is to ensure patient comfort and safety during the procedure.
What is Lidocaine Hydrochloride jelly?
A topical analgesic used to relieve the pain of skin lesions or to numb skin for a superficial procedure. Lidocaine hydrochloride jelly, 2% is indicated for prevention and control of pain in procedures involving the male and female urethra, for topical treatment of painful urethritis, and as an anesthetic lubricant for endotracheal intubation (oral and nasal).
What do doctors use to deaden the eye?
Doctors commonly use topical anesthetic eye drops to deaden the eye for various procedures. These drops typically contain agents like proparacaine or tetracaine, which temporarily numb the surface of the eye to minimize discomfort during examinations or treatments. The anesthetic effect allows for procedures such as foreign body removal or cataract surgery to be performed with less pain for the patient.
What type of anesthetic do they give you during LASIK?
For both LASIK and PRK, the patient's eye is numbed with anesthetic drops. No injections are necessary. The patient is awake and relaxed during the procedure.
What does the electrical stimulation of the brain help determine during a pallidotomy?
Electrical stimulation of the brain through the electrode can help determine exactly which structure is being stimulated.
What is a microelectrode probe used for during a pallidotomy?
Once the burr hole is made, the surgeon inserts a microelectrode probe, which is used to more precisely locate the GPi.
What is a stereotactic frame used for during a pallidotomy?
In order to precisely locate the GPi target, and to ensure the probe is precisely placed in the target, a "stereotactic frame" is used.
Why is the electrode tip heated during a pallidotomy?
When the proper target is located, the electrode tip is briefly heated, carefully destroying the surrounding tissue to about the size of a pearl.
