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...

Urinary Tract Calculi VI: Surgical Management

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Summary

This study compared general and spinal anesthesia for micro-percutaneous nephrolithotomy (microperc) kidney stone removal. Both anesthesia types demonstrated similar success rates and complication profiles, making microperc a viable option for kidney stone treatment.

Area of Science:

  • Urology
  • Anesthesiology
  • Nephrology

Background:

  • Micro-percutaneous nephrolithotomy (microperc) is a minimally invasive procedure for kidney stone removal.
  • The choice of anesthesia can impact patient outcomes and procedural feasibility.

Purpose of the Study:

  • To compare the clinical and operative effects of general anesthesia versus spinal anesthesia in patients undergoing micro-percutaneous nephrolithotomy (microperc).

Main Methods:

  • Retrospective review of 116 patients who underwent microperc.
  • Patients were divided into two groups: general anesthesia (n=53) and spinal anesthesia (n=63).
  • Comparison of perioperative variables and outcomes including operative time, success rates, and complications.

Main Results:

  • No significant differences were observed in stone-free rates (90.5% vs. 93.6%), complication rates, or pain scores between the two anesthesia groups.
  • Operative times were significantly shorter in the spinal anesthesia group (40.98 ± 26.45 min) compared to the general anesthesia group (59.62 ± 32.56 min).
  • Fluoroscopy times, hemoglobin drop, and hospitalization duration were similar between groups.

Conclusions:

  • Micro-percutaneous nephrolithotomy (microperc) is a feasible and effective treatment for kidney stones under both general and spinal anesthesia.
  • Spinal anesthesia presents a viable alternative, particularly for patients at high risk for general anesthesia or those with anesthesia-related anxieties.
