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...

Electroacupuncture effectively reduces bladder overdistension and speeds up spontaneous micturition after spinal anesthesia. This therapy shows promise for treating postanesthetic bladder dysfunction.

Area of Science:

  • Anesthesiology
  • Neuromodulation
  • Urology

Background:

  • Postanesthetic bladder dysfunction is a common complication following spinal anesthesia.
  • Urinary retention and bladder overdistension can lead to patient discomfort and prolonged hospital stays.

Purpose of the Study:

  • To evaluate the efficacy of electroacupuncture in restoring bladder function after spinal anesthesia.
  • To assess electroacupuncture's impact on key indicators of postanesthetic bladder recovery.

Main Methods:

  • A randomized controlled trial involving 61 patients undergoing spinal anesthesia.
  • Patients were assigned to either electroacupuncture therapy or a control group receiving no intervention.
  • Primary outcomes included bladder overdistension and urinary retention; secondary outcomes involved time to micturition and voided volume.

Effects of Different Connection Modes of Electroacupuncture on Electrocardiogram and Nerve Discharge in Rats

Published on: January 3, 2025

Main Results:

  • Electroacupuncture significantly decreased the incidence of bladder overdistension (16.1% vs. 53.3%, P < 0.01).
  • Patients receiving electroacupuncture experienced a shorter time to spontaneous micturition (228 min vs. 313 min, P < 0.001).
  • No significant differences were observed in postoperative urinary retention, urine volume, or adverse events between groups.

Conclusions:

  • Electroacupuncture is effective in reducing bladder overdistension and accelerating micturition recovery post-spinal anesthesia.
  • This neuromodulation technique presents a potential therapeutic option for managing postanesthetic bladder dysfunction.
