What are some epidural needle tips?

Epidural anesthesia is divided into single epidural and continuous epidural anesthesia, which can be used for both pediatric and adult patients. It is suitable for rectal surgery and anal surgery with longer operation time, such as anoplasty.

Operation method: The patient is placed in a lateral position with the back arched backwards and both knees close to the abdominal wall. At the midpoint of the two spinous processes above and below the selected vertebral space, make a mound, then enter the needle vertically, inject a small amount of drugs while entering the needle, and withdraw the needle to the ligamentum flavum (resistance increases), select a slightly thicker needle, pierce from the mound to the ligamentum flavum and withdraw, pierce the spoonhead epidural puncture needle along the eye of the needle, and when it reaches the ligamentum flavum, the resistance increases significantly, then withdraw the needle core, connect a small glass tube, filled with a small amount of isotonic saline, then, while Then, while rotating the direction of the needle slowly into the side to test the resistance. When penetrating the ligamentum flavum, the resistance suddenly disappears and the saline is inhaled, indicating that the needle tip has entered the epidural space. The glass tube is removed, the syringe is attached, and the aspiration is free of cerebrospinal fluid and blood, confirming that the epidural cavity is indeed inside the epidural cavity and has not entered the vessels or subarachnoid space by mistake. If single epidural anesthesia is chosen, the drug can be injected. When continuous epidural anesthesia is chosen, a plastic catheter is inserted into the needle to a length of 3 cm beyond the tip of the needle, the puncture needle is withdrawn, the plastic catheter is left in place, and the medication is administered via the catheter in several doses according to the surgical needs. After the operation, the catheter is removed. The commonly used anesthetic drugs are: 2% lidocaine, 0.5% bupivacaine, etc., with a small amount of epinephrine added.
