|July 1, 1984
Summary
This study evaluated a new fluoropolymer-covered stainless steel epidural catheter for labor pain relief. While it prevents kinking, issues like leakage, injection port problems, and high cost were noted.
Area of Science:
- Anesthesiology
- Biomaterials Engineering
Context:
- Lumbar epidural anesthesia is a common method for labor pain management.
- New medical devices are continuously developed to improve patient outcomes and procedural efficiency.
Purpose:
- To evaluate the performance and identify limitations of a novel stainless steel spiral epidural catheter covered with fluoropolymer.
- To assess its suitability for epidural anesthesia in laboring patients.
Summary:
- A new epidural catheter featuring a stainless steel spiral core and fluoropolymer coating was tested in approximately 115 patients undergoing lumbar epidural anesthesia for labor pain relief.
- The primary advantage observed was the catheter's resistance to kinking.
- Identified disadvantages included leakage at the skin or injection port, difficulties with the injection port mechanism, a recommendation for a 17-gauge epidural needle, and a high cost.
Impact:
- Provides insights into the clinical performance of a novel epidural catheter design.
- Highlights potential areas for device improvement, such as sealing mechanisms and port accessibility.
- Informs clinicians and manufacturers about the trade-offs between kink resistance and other functional aspects of epidural catheters.

01:11Local 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...
01:29Local 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...

01:16Local 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.
