Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.
One of the advantages of...

Local Anesthetics: Clinical Application as Surface, Infiltration, and Conduction Block Anesthesia

Local Anesthetics: Clinical Application as Surface, Infiltration, and Conduction Block Anesthesia

Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...

Ankle Joint

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Area of Science:

Anesthesiology
Orthopedic Surgery
Anatomy

Background:

Peripheral nerve blocks are increasingly utilized in orthopedic surgery.
The foot block is a viable anesthesia option for forefoot and midfoot procedures.
Anatomical challenges with the tibial nerve necessitate technique modifications.

Purpose of the Study:

To propose and evaluate a modified foot block technique.
To address difficulties associated with the traditional tibial nerve block.
To improve anesthesia delivery for foot and ankle surgeries.

Main Methods:

Anatomical measurements of tibial and sural nerves were performed on 60 dissected specimens.
A modified technique involved specific needle insertion points for tibial, sural, saphenous, and peroneal nerves.
The modified technique was clinically evaluated in 84 operative procedures.

Main Results:

Tibial nerve depth and distance from the Achilles tendon were precisely measured.
Sural nerve distance from the lateral malleolus was determined.
A 93% success rate for complete foot block was achieved in 84 clinical cases.

Conclusions:

The modified foot block technique demonstrated a high success rate comparable to existing methods.
This technique simplifies patient positioning for anesthesia.
The modified approach allows for complete foot blockade using only two skin injection sites.
