Local Anesthetics: Clinical Application as Epidural Anesthesia

Local Anesthetics: Clinical Application as Epidural Anesthesia

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

Local Anesthetics: Clinical Application as Spinal Anesthesia

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...

Summary

This summary is machine-generated.

Spinal epidural lipomatosis (SEL) is a rare spinal condition involving excess fat growth. Treatment includes weight loss, corticosteroid weaning, or surgery for severe cases.

Radiology

Background:

Spinal epidural lipomatosis (SEL) is a rare condition characterized by abnormal fat tissue growth within the spinal canal.
Its exact cause is unknown, but it is frequently linked to obesity, corticosteroid use, and hormonal imbalances (ACTH-cortisone).

Observation:

SEL can be asymptomatic and discovered incidentally on imaging.
Symptomatic presentations include low back pain, leg weakness, sensory disturbances, radiculopathy, claudication, and cauda equina syndrome.

Findings:

The review covers the etiology, clinical presentation, and diagnostic findings of SEL.
A case report is included to illustrate the condition's characteristics and management.

Implications:

Early diagnosis and management are crucial to prevent neurological deficits.
Interdisciplinary treatment approaches, including lifestyle changes and surgical intervention, are vital for SEL patients.
