Although epidural block is a well-established anesthetic method, we often experience a failed epidural block. The success rate of epidural block is dependent on the accurate identification of the epidural space and successful location of the catheter within the epidural space. Rarely, it is missed to identify the epidural space with a loss of resistance method due to a variable anatomy of the epidural structure. Occasionally, an epidural catheter may pass into the extra-epidural space. We report 2 cases of misplacement of an epidural catheter in the extra-epidural space. These cases highlights the need for careful identification of the epidural space during epidural puncture and confirming the location for successful placement of the catheter within the epidural space by using a test block with a test dose of the local anesthetic drug after epidural catheterization.

The use of fluoroscopy guidance together with the loss of resistance technique during epidural injections has been advocated lately; moreover, epidural injections in the absence of fluoroscopic guidance have a high rate of inaccurate needle-tip placement during the injections. However, the approach to the lower cervical and upper thoracic epidural space may be challenging due to its obscure lateral fluoroscopic views from overlying normal tissue structures. In this case, we report an alternative oblique C-arm fluoroscopy guided view approach to supplement the standard anterior-posterior and lateral fluoroscopic views to facilitate successful needle placement and precise anatomical localization of the epidural space.

The epidural blood patch is a relatively new technique for treatment of post spinal headache. Injection of autologous blood into the epidural space afforded prompt and permanent relief. "Pathcing" the dura hole with autologous blood is the most direct therapy available. It has always been used within a few days of development of headache. This procedure may be considered for patients who continue to experience in capacitating symptoms following a trial of supportive therapy. In our patient the epidural blood patch was used successfully on four cases after the development of headache.

This article aims to study the factors affecting the flexibility of the tip of an epidural anesthesia catheter. The flexibility of the tip of the epidural anesthesia catheter was tested with a softness tester from four aspects:raw materials, tip structure, tip processing technology, and the outer diameter of the catheter. Highly flexible and malleable polymer material with a smooth tip, the tip softening process and the proper outer diameter can effectively improve the tip flexibility of the epidural anesthesia catheter.

BACKGROUND: Neck flexion has been shown to increase cranial spread of contrast agent when a small fixed volume was injected into the high thoracic epidural space. The purpose of this study was to evaluate the effect of volume of contrast medium on its distribution through the high thoracic epidural space during neck extension and flexion using the rabbit model. METHODS: An epidural catheter was introduced into the epidural space of New Zealand white rabbits with the tip located at the T3-4 intervertebral level. The neck was extended or flexed (n = 8 for each group), and the contrast medium was injected with the volume increasing by increments of 0.1 ml/kg, up to 0.3 ml/kg. The spread of contrast medium was determined by counting the number of vertebral body units using lateral epidurographic images. RESULTS: In both groups, the total spread of contrast medium was similar, increasing continuously with injected volume. The cranial spread was greater in the flexion group than the extension group. However, the caudal spread was greater in the extension than in the flexion group. In the extension group, the contrast medium spread caudally about twice as far as it spread cranially, but there was no statistically significant difference between cranial and caudal spread in the flexion group. CONCLUSIONS: In the high thoracic epidural space of rabbit, the contrast medium of varying doses showed limited cranial spread. The flexion of the neck increased cranial spread and extension of the neck increased caudal spread.

Cysticercosis of the central nerve system seldom involves spinal structures. When it does, the parasites grow much more often in the subarachnoid space than within the cord or epidural space. Recently we have experienced a cases of intramedullary cysticercosis in thoracic cord, which was characterized by paraparesis and voiding difficulty of 1 1/2 years duration in 34-year old man, and the patient's symptoms were improved after operation. We discuss this rare condition with brief review of the literature relevant to spinal cysticercosis.

10.A Negative Pressure Method Using a CVP Manometer for the Ascertainment of the Epidural Space .
Korean Journal of Anesthesiology 1989;22(6):922-925
To identify the epidural space various methods have been recommended and the methods are divided into two major categories, either loss of resistance or negative pressure technics. A s#yringe technic to feel loss-of-resistanse is now widely used clinically due to its reliability and simplicity. However, in some instances, it is very difficult to recognize the epidural space despite using the above methods so that the need for a more safe and easier one is required. After the patient is placed in a sitting flexed position, an 18 gauge Tuohy needles is inserted epidurally at the lumbar area with a saline filled CVP manometer connected via a 3-way stopcock, then a sudden drop of pressure is usually observed and a fluctuation of the pressure can be observed in the water column of the manometer according to the changes in positions, respiration and heart beat. Although this method can be criticized because the technique is somewhat cumbersome and is difficult for retrial when the dura has been punctured, the authors appreciate the experimental values of the technic and suggest its aduantanges as follows: 1) it is a visual thchnic. 2) the measurement of epidural pressure is possible. 3) it prevents back-drip of local anesthetic solution with a 3-way stopcock. 4) it is useful as an index for determination of local anesthetic volume to be injected.
