[Knot on the epidural catheter, a rare complication: a case report]

Area of Science:

• Anesthesiology
• Obstetrics
• Case Reports

Background:

• Epidural analgesia and anesthesia are common for labor pain and Cesarean sections.
• Complications, though rare, can occur during epidural catheter insertion, use, or removal.

Observation:

• During removal of an epidural catheter 24 hours after Cesarean section, significant resistance was met.
• The catheter was eventually removed with difficulty, revealing a knot at its tip.
• The patient experienced no pain during catheter removal.

Findings:

• Knot formation on an epidural catheter is a rare but documented complication.
• Management involves gentle traction, patient repositioning, and potentially imaging (X-ray/MRI) if removal is difficult.
• Recommendations include limiting catheter insertion depth to 4-5 cm to minimize risk.

Implications:

• Awareness of this complication is crucial for anesthesiologists.
• Adherence to recommended practices can prevent epidural catheter knotting.
• Prompt and appropriate management ensures patient safety and minimizes discomfort.
