Extradural block is a form of treatment described as early as the beginning of the present centuries. It has since had positive criticism from a number of authors in different countries. Epidural injections of steroids with or without local anesthetic have become an occasional method of conservative treatment in sciatica & lumbago, especially in acute case. We assess the results of continuous epidural block with steroids and local anesthetics in sciatica & lumbago. From July 1994 to June 1995, we treated 46 case of lumbago and sciatica using continuous epidural block with steroids and local anesthetics. After placement of 17-Gauge Tuohy needle in the epidural space by the technique of loss of resistance, 0.25% bupivacaine 5 cc and triamcinolone 40 mg was administered and then epidural catheter was placed and connected to multiday infusor(Paragon) using 1% lidocaine with continuous infusion rate of 1 ml/hour. Usually, the catheter was removed after 1~2 weeks and then treated with the physical therapy. At the time of patient's discharge, 69.5% of all cases showed excellent or good results. Of particular note, 26 of the 46 cases were followed up by telephone. At present, in using Of particular note, 26 of the 46 cases were followed up by telephone. At present, in using continuous epidural block procedure, a relief in symptoms showed in 65.5% of these 26 cases. Continuous epidural block provides shortening of the recovery time from pain, avoidance of long period bed rest and early physical therapy and exercise. Therefore, continuous epidural block is simple and safe in the treatment of lumbago and sciatica, especially in acute phase.

It is important to treat cancer-related pain in cancer patients to ensure the life quality of the patient, as well as to improve their life span. It has been estimated that at least 5% of cancer patients have pain refractory to medical treatment. Therefore, the need for epidural or intrathecal analgesia with opioids and local anesthetics is indicated if systemic treatment has failed. Intrathecal catheter placement and implantation of the injection port for administration of opioids and local anesthetics may improve pain relief in patients who are unresponsive to epidural routes. Although intrathecal implantation has several complications, similar infection rates have been reported between intrathecal and epidural administration. In addition, intrathecal administration showed better outcomes, including improved pain control, lowered daily doses, and an improvement in the level of drowsiness experienced when compared to epidural administration. We report here a case in which a terminal cancer patient was treated using an intrathecal catheter and subcutaneous port. The patient had cancer-related pain that could not be controlled by epidural opioid administration. Based on the results presented here, we suggest that intrathecal implantation is a feasible long term pain management method for intractable cancer pain patients.

Background: Authors modified the traditional continuous axillary brachial plexus block technique of Selander for purpose of increasing success rate and decreasing complications by use of commercial epidural anesthesia set. Method: Thirty-nine patients scheduled for upper extremity operations were injected with 40 ml of anesthetic solution by axillary perivascular technique, using 23~25G immobile needle at 2 cm from the pectoralis major. Tuohy needle was immediately introduced at 4 cm from the pectoralis major and pierced the expanded neurovascular sheath at an angle of 30 degree to the skin. The "pop" was well noted well. Needle was advanced 0.5 to 3.0 cm and epidural catheter introduced through the needle. After removal of needle, occlusive dressing was done. Tip of catheter and spread of solution were demonstrated by fluoroscopy with contrast dye after completion of procedure. Result: Catheter insertion was successful at first attempt for all case. Total length of insertion was from 6 to 13($10.0{\pm}1.7$) cm. Tip of catheter was placed in infraclavicular space(66.7%), about the humeral head(17.9%) and in upper arm in 3 cases as U-shape(7.9%). Catheters were maintained for $6.7{\pm}2.6$(3-12) days. There were no complications such as: perforation of major vessels, needle trauma to nerve, infection, bleeding or hematoma. Conclusion: This study demonstrated continuous axillary brachial plexus block with epidural anesthesia set is safe, easy and convenient modification of technique of Selander.

The superior hypogastric plexus block (SHPB) is used for treating pelvic pain, especially in patients with gynecological malignancies. Various approaches to this procedure have been reported due to the anatomic obstacles of a high iliac crest or large transverse process of the $5^{th}$ lumbar vertebra. Here, we report a new technique of superior hypogastric plexus block using a unilateral single-needle approach to block the bilateral superior hypogastric plexus with a Tuohy needle and epidural catheter. We have confidence that this new technique can be another option in performing the SHPB when the conventional bilateral approach is difficult to perform.

Subdural block is a rare but well recognized complication of epidural anesthesia. The placement of local anesthetics into the subdural space can lead to potentially life-threatening conditions. A healthy 46-year-old women underwent total abdominal hysterectomy under continuous lumber epidural anesthesia. The technical procedure for continuous epidural catheterization went smoothly without a single problem. However, signs of high epidural block such as apnea, cranial nerve paralysis and pupil dilatation developed gradually, about 20 minutes after the epidural injection of 2% lidocaine 20 ml through the epidural catheter. Such extensive segmental block can only be explained as the result of injection into subdural space even if it was not confirmed radiologically.

Postoperative pain relief and the side effects of epidurally injected morphine were investigated in 10 patients who received thoracotomy. Epidural morphine injection was given via an epidural catheter after thoracotomy. The pain score[VAS] and repiratory rate were decreased and the SaO2, tidal volume and vital capacity were increased significantly after epidural morphine injection. The analgesia of epidural morphine lasted for 13 hours with average. The side effects of epidural morphine were few and mild, but urinary retention was in 10%[1/10] of total patients.

Background: Epidural steroid injection(ESI) is often adminstered to treat lower back pain, but its effect iveness on postepidural backache have not yet been determined. Methods: Sixty patients scheduled for cesarean section under epidural anesthesia were randomly assigned to receive, 1 ml of normal saline(Group 1), or 5 mg of dexamethasone (Group 2), epidurally via indwelling catheter after delivery. Results: The incidences of postepidural backache occured significantly more often in Group 1(56.7%) than in Group 2(26.7%)(P<0.05). There was a significant association between postepidural backache and multiple attempts at epidural needle placement. Conclusion: Epidural dexamethasone has a preventive effect on postepidural backache.

Continuous epidural infusion, a combination of local anesthetic and opioid, have been widely administered for treatment of chronic cancer pain. A serious complications of epidural block is paraplegia which can also be caused by : direct spinal cord injury, epidural hematoma, epidural abscess, ischemic change, neurotoxicity, preexisting disease. Continuous epidural block for pain control of patient with cervical cancer was performed at $T_{12}/L_1$ interspace. A 4 cm catheter was inserted cephalad into the epidural space. After four months, back pain and motor weariless of lower extremities progressively developed. Spine CT showed bony destruction and soft mass-like lesion at $T_9$ & $T_{12}$ spine. We propose paraplegia was caused by spinal cord compression which resulted from vertebral metastasis of cervical cancer.

Background: Pain due to spinal stenosis is one of the major causes of low back pain, and it sometimes does not respond to conservative treatment. We postulated that anterior epidural irrigation could be a good choice for treating lumbar spinal stenosis patients. However, the effects and theoretical basis of anterior epidural irrigation have not been investigated for spinal stenosis. So, this study was designed to identify the clinical efficacy of anterior epidural irrigation for treating lumbar spinal stenosis. Methods: 71 patients with lumbar spinal stenosis underwent anterior epidural irrigation. Anterior epidural irrigation was performed with normal saline and a mixture of local anesthetic with steroid through a catheter under fluoroscopic guidance. The findings were evaluated with using visual analogue scales for low back pain and leg symptoms. Results: Relief from low back pain and leg pain was observed for up to 12 months after anterior epidural irrigation. None of the patients showed any deterioration of their motor or sensory deficits during follow up. Conclusions: Anterior epidural irrigation is effective for the relief of back and leg pain in spinal stenosis patients.
