■ Catheter

Prevent obturation
Spring coil is embedded at the end tip to enhance the strength, which helps to prevent obturation of catheter caused by tight screwing of connector for long period.

Easy detection
Radiopaque agent is linearly embedded for easy detection of catheter piece left, in case of breakage inside body.

How the Epidural Anesthesia is preferred

Epidural Anesthesia is a type of regional anesthesia, which has been widely recognized in Japan since its adaptation at surgical operation for Showa Emperor in 1987. In this case it is also known that Continuous Epidural Anesthesia with indwelling catheter was used and had positive outcomes, for desensitization and protection against pulmonic complication.
Epidural Anesthesia procedure , in comparison to Spinal Anesthesia, has an advantage of safe and easy control of pain after surgery, by continuous administration of agent through indwelling catheter.

Site of application

Widely applicable from thoracic region to sacrum and commonly used in general abdominal surgery, such as gynecological, urological, perineal, upper limb, cervical and thyroid gland.
Effectively used for desensitization of thoracic and upper abdominal region, in parallel use with Spinal Anesthesia. Also effective in lowering the risk of surgery by redusing amount of Spinal Anesthesic Agent, for example in case of operation of aged patient with hypohepatia.
Other than surgery, this procedure is also used in several fields such as painless labor, cingulum, and relief of cancerous pain.

In 1901, Dr. Jean E. Sicard has approached the first trial of sacral (Epidural) Anesthesia, aiming to ease sciatica of a patient.
Dr. Achille M. Dogliotti reported his research on procedure to inject regional anesthesic agent into epidural space. This procedure was widely introduced to Europe and South America.
Dr. William Lemmon attempted continuous Spinal Anesthesia, using 17gauge flexible silver needle through a hole placed in the middle of surgical table.
In 1944, Dr. Tuohy had improved the problem of this method (fixation of needle) by indwelling ureteral catheter into subarachnoid cavity through 15gauge Huber point spinal needle, and implemented Continuous Spinal Anesthesia.
Later, this method had become the origin of Epidural Anesthesia.
