Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

380
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.

Summary

Isolated limb infusion (ILI) offers a 70% limb salvage rate for sarcomas. Patients responding to ILI with chemotherapy show significantly improved progression-free survival, overall survival, and disease-specific survival.

Area of Science:

  • Oncology
  • Surgical Oncology
  • Regional Chemotherapy

Background:

  • Isolated limb infusion (ILI) is a regional chemotherapy technique for unresectable extremity malignancies.
  • This method delivers high-dose chemotherapy directly to the affected limb, minimizing systemic exposure.
  • ILI is employed for limb-threatening sarcomas to improve local control and limb salvage.

Purpose of the Study:

  • To evaluate the long-term outcomes of isolated limb infusion (ILI) in patients with limb-threatening sarcomas.
  • To assess survival rates, progression-free survival, and limb salvage following ILI treatment.
  • To identify factors associated with better outcomes after ILI for extremity sarcomas.

Main Methods:

  • A retrospective review of patients with extremity sarcomas treated with ILI using melphalan and dactinomycin.
  • Data collected from 2008 to 2023 at a single institution.
  • Analysis included response rates, progression-free survival (PFS), overall survival (OS), disease-specific survival (DSS), and limb salvage rates.

Main Results:

  • The study included 61 patients, with a median follow-up of 6.9 years.
  • Overall response rate was 48.3% (21.7% complete response, 26.7% partial response), and disease control rate was 65%.
  • Responders demonstrated significantly longer PFS, OS, and DSS compared to non-responders. The 5-year limb salvage rate was 70%.

Conclusions:

  • Isolated limb infusion (ILI) achieves high limb salvage rates (70% at 5 years) for extremity sarcomas.
  • Patients achieving a response (complete or partial) to ILI have significantly better long-term outcomes.
  • ILI is an effective treatment modality for limb-threatening sarcomas, improving survival and limb preservation.
