Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

2.2K
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.

Local Anesthetics: Clinical Application as Spinal Anesthesia

2.0K
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

    Summary

    Forequarter amputation, a rare surgery for shoulder tumors, was performed using regional anesthesia. This case study explores an alternative to general anesthesia for this complex procedure.

    Area of Science:

    • Surgical Oncology
    • Anesthesiology
    • Orthopedic Oncology

    Background:

    • Forequarter amputation is an uncommon surgical option for upper limb and shoulder girdle tumors.
    • General anesthesia is typically employed for this extensive procedure.
    • Alternative anesthetic techniques may offer benefits for specific patient populations.

    Observation:

    • A case of forequarter amputation via the posterior approach was performed.
    • The indication for surgery was a soft-tissue sarcoma.
    • The surgical procedure was conducted under regional anesthesia.

    Findings:

    • The forequarter amputation was successfully performed under a brachial plexus block with venous sedation and local anesthesia.
    • This anesthetic approach provided an alternative to general anesthesia for the surgical management of the sarcoma.
    • The posterior approach facilitated the forequarter amputation.

    Implications:

    • Regional anesthesia can be a viable alternative to general anesthesia for forequarter amputations.
    • This approach may reduce risks associated with general anesthesia in select patients.
    • Further research into anesthetic techniques for forequarter amputation is warranted.
