Study Notes

Bier Block Procedure

Involves intravenous administration of anesthesia to an extremity.
Requires exsanguination of the limb, tourniquet application, and injection of anesthetic.
Uses a double-cuff pneumatic tourniquet to prevent the mixing of anesthetic with circulating blood.
Circulating technician's role includes obtaining supplies: double-cuff tourniquet, webril cotton wrap, Esmarch bandage, IV catheters, syringes, and local anesthetics (0.25%-0.5% lidocaine).
Limb elevation and wrapping with Esmarch bandage are crucial for blood removal prior to anesthetic injection.
Post-procedure, patients must be assisted in protecting anesthetized limbs until sensation returns.

Spinal, Epidural, and Caudal Blocks

Positioning and support for the patient are critical during spinal and epidural block administration.
Anesthesia trays contain necessary supplies including needles, syringes, and drugs.
Patients are typically positioned sitting or lateral recumbent for accessibility during injection.
Maintain warmth for the patient while ensuring exposure for the anesthetic procedure.
An anesthetic is injected in the skin prior to spinal needle insertion to minimize discomfort.
Monitor patient for signs of light-headedness or nausea, and prepare to administer oxygen if needed.
Instruct patients to remain still during needle insertion to avoid complications.

Techniques for Administering Anesthesia

Continuous central blocks can allow multiple anesthetic injections during a procedure.
The catheter may be secured in place following spinal or epidural injection.
Post-injection, help reposition the patient slowly and carefully, ensuring legs are moved as a unit.
Caudal blocks involve positioning the patient prone with slight bed flexion and open buttocks for access.
Always practice safety with disposal of needles; never discard them in trash.
The anesthetist monitors blood pressure closely as anesthetics can lower it by blocking sympathetic nerves.

Patient Monitoring and Emergency Preparedness

Be aware of the critical phase following anesthetic administration; monitor for hypotension.
IV fluids may be administered to manage blood pressure drops, with medications like ephedrine as needed.
Be prepared with emesis basins and suction equipment in case of nausea.
Prompt action is essential if the patient is pregnant, as low blood pressure can lead to fetal distress.
