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.

Summary

This summary is machine-generated.

Local ischemia during laparoscopic partial nephrectomy for kidney cancer preserves kidney function better than traditional renal artery clamping. This technique expands minimally invasive surgical options for renal cell carcinoma.

Area of Science:

Urology
Surgical Oncology
Nephrology

Background:

Laparoscopic partial nephrectomy offers comparable oncological outcomes to open surgery for kidney cancer.
A key limitation of laparoscopic partial nephrectomy is prolonged warm ischemia time, potentially impairing kidney function.
Reducing ischemic injury is crucial for preserving renal function after partial nephrectomy.

Purpose of the Study:

To evaluate the impact of local ischemia techniques versus traditional renal artery clamping on kidney function after laparoscopic partial nephrectomy.
To determine if local ischemia can expand the indications for minimally invasive kidney cancer surgery.

Main Methods:

A retrospective study of 60 patients undergoing laparoscopic partial nephrectomy between January 2009 and June 2012.
Patients were divided into two groups: 34 undergoing renal artery clipping and 26 undergoing segmental/subsegmental branch clipping (local ischemia).
Renal function was assessed before and at 3 months after surgery in both groups.

Main Results:

Patients undergoing local ischemia experienced a significantly lower decline in kidney function at 3 months post-surgery compared to those with renal artery clamping.
No significant difference in oncological outcomes was implied between the two methods, but functional data favored local ischemia.

Conclusions:

Local ischemia during laparoscopic partial nephrectomy significantly mitigates the decline in kidney function compared to standard renal artery clamping.
This technique holds promise for expanding the applicability of minimally invasive partial nephrectomy for renal cell carcinoma, improving patient outcomes.
