Local Anesthetics: Clinical Application as Epidural Anesthesia

669
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Local Anesthetics: Clinical Application as Spinal Anesthesia

1.3K
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...

Area of Science:

  • Pain Management
  • Neurosurgery
  • Radiology

Background:

  • Lumbar disc herniation is a common cause of sciatica, impacting 1-5% of the population annually.
  • Epidural corticosteroid injections offer an option for refractory sciatica pain.
  • Transforaminal epidural injections target the pathology directly at the nerve root.

Purpose of the Study:

  • To evaluate the efficacy of transforaminal infraneural epidural injections with corticosteroids for radiculopathy due to acute lumbar disc herniation.

Main Methods:

  • A descriptive, retrospective, single-center study.
  • Included patients with radiculopathy secondary to acute lumbar disc herniation treated between 2022-2024.
  • Inclusion criteria: symptom onset <12 weeks, persistent symptoms >8 weeks, clinical signs, MRI-confirmed discopathy, age ≥18.

Main Results:

  • Transforaminal infraneural epidural steroid injection provides effective analgesia.
  • Achieved with a smaller corticosteroid dose compared to other methods.
  • Minimally invasive treatment for refractory radicular pain.

Conclusions:

  • Transforaminal blocks are effective nonsurgical alternatives for radiculopathy from acute lumbar disc herniation.
  • Offer targeted analgesia with reduced corticosteroid volume.
  • Potentially safer due to decreased systemic exposure and procedural risks.
