  • We have inserted epidural catheter for single or continuous injection of a drug for epidural analgesia. It is important to localize the tip of epidural catheter in appropriate site to acquire the most effective analgesia. In epidural block, we observed course and location of the tip of epidural catheter. Subject: 70 patients were divided into group I(non-injection of saline group during catheter insertion) and group II(injection group during catheter insertion). Group I included cervical(n=20), thoracic(n=10), and lumbar(n=20) epidural group. Group II, cervical(n=10), and lumbar(n=10) epidural group. Method: 19G FlexTip $Plus^{TM}$ Epidural Catheter ($Arrow^{(R)}$) was inserted 10cm cephaladly in epidural space with(group II) or without(group I) saline flushing. We observed course and location of the tip of epidural catheter by C-arm image intensifier during injection of contrast media ($Omnipaque^{(R)}$). Result: In group I, the number of tips of epidural catheters located within 2 cm from inserted site were: cervical 14/20(70%), thoracic 2/10(20%). lumbar 16/20(80%). In thoracic epidural blocks, tips of epidural catheters were more cephaladly located than with cervical and lumbar epidural blocks. With cervical epidural blocks, the number of tips of epidural catheters located within 2 cm from insertion site were less in group II than group I (20% vs. 70%). But no significant differences were noted between group I and group II with lumbar epidural block(90% vs. 80%). The number of tips of epidural catheters located around a predicted site were: cervical 2/20(10%), thoracic 4/10(40%), lumbar 0/20(0%) in group I, and cervical 2/10(20%), lumbar 1/10(10%) in group II. Conclusion: It was impossible to predict the exact location of tips of epidural catheters by measuring the inserted length without epidurogram. With many cases, tips of epidural catheters were located around the insertion site in lumbar epidural blocks, and in some cases around the predicted site in thoracic epidural blocks. The results suggests that epidural block should be done at a point near the required band of analgesia.

  • A 50-year-old female patient developed severe right neck and upper extremity pain, hyperesthesia and allodynia during cervical epidural block. Her pain was diagnosed as neuropathic nature. She was treated with repeated stellate ganglion block (SGB) and electrical stimulation (EST). After 3 weeks of treatment, symptomatic relief was achieved, but a mild degree of hyperesthesia and motor weakness was remained. However, she refused all treatment. So treatment was stopped. In a follow-up done, 15 weeks after the nerve injury, she had recovered without complications.

  • Continuous epidural block can be useful in the management of acute and chronic pain. For the most effective analgesia, it is important to localize the tip of epidural catheter and the spread of radiopaque dye. Epidural catheterization was performed in 12 patients on the sitting position. Catheters were advanced by 10 cm cephalad in the cervical epidural space by median approach and radiopaque dye 3 ml was injected through the catheters. The position of cervical epidural catheters and the spread of dye was confirmed by radiography. The course of epidural catheter were: coiled 3/12 (25%), loop 2/12 (16.7%), straight 2/12 (16.7%). In 8 cases, the tip of epidural catheters were located within one vertebral segment from the level of insertion site. Radiopaque dye spreaded average 3.68 vertebral segment to cranially and 1.67 vertebral segment to caudally from the insertion site.

  • Background : This study was designed to determine if cervical epidural depth has any correlation with age, height, weight, ponderal index and neck clrcunference. Methods : Data was obtained from 102 patients successfully anesthetized with cervical epidural block. Patients were categorized into 4 groups: male C6-7, male C7-T1, female C6-7, female C7-T1 then statistically compared and analyzed. Results : The mean and standard deviation of epidural depth of male C6-7, male C&-T1, female C6-7, female C7-T1 groups were respectively as follows: 41.1+/-6.0, 47.1+/-5.6, 37.9+/-6.0, 46.4+/-5.6 mm. The results showed cervical epidural depth is well correlated with body weight and ponderal index; moderately correlated with neck circumference: slightly correlated with age; no correlation with height.

  • Magnetic resonance image (MRI) is the most sensitive imaging test of the spine in routine clinical practice. Unlike conventional x-ray examinations and computed tomography scans, high-quality magnetic resonance images can be assured only if patients are able to remain perfectly still. However, some patients find it uncomfortable to remain still because of pain. In that condition, interlaminar cervical epidural injections can reduce pain and allow the procedure. When using air with the "loss of resistance" technique in epidural injections to identify the epidural space, there is the possibility of injected excessive air epidurally to mimic a herniated disc. We describe a case report of epidural air artifact in a cervical MRI after cervical epidural injections.

  • Migraine is a disabling headache that can occur with or without aura. We present here a case of migraine that was effectively managed by a series of cervical epidural blocks. A 41-year-old woman who had suffered from severe headache on her left temporal area for 12 years visited our pain clinic. Her 11-point numeric pain rating scale was 10 out of 10 at the first visit and the symptoms were associated with homonymous visual disturbances, paresthesia on the left face, shoulder and arm, and general weakness. For the first 5 years after the headaches began, her headache was relatively well controlled by acetaminophen; after then, the acetaminophen wasn't effective. After wandering from this hospital to the next one in search of relief, she managed to visit our pain clinic. We tried several blocks including cervical epidural block, and she was continuously medicated with sumatriptan. Her headache was gradually relieved. Now, her 11-point numeric rating scale is 1-2 out of 10 at the most during her headache attacks.

  • Background: Epidural steroid injection is an established treatment modality for intervertebral disc prolapse to radiculopathy. In cases where two levels of radiculopathy are present, two separate injections are warranted. Herein, we present our experience of management of such cases with a single epidural injection of local anaesthetic, tramadol and methylprednisolone, and table tilt for management of both radiculopathies. Methods: 50 patients of either sex aged between 35-65 years presenting with features of cervical and lumbar radiculopathic pain were included and were subjected to single lumbar epidural injection of local anaesthetic, tramadol and methylprednisolone, in the lateral position. The table was then tilted in the trendelberg position with a tilt of 25 degrees, and patients were maintained for 10 minuted before being turned supine. All patients were administered 3 such injections with an interval of 2 weeks between subsequent injections, and pain relief was assessed with a visual analogue scale. Immediate complications after the block were assessed. Results: Immediate and post procedural complications observed were nausea and vomiting (20%), painful injection site (4%), hypotension (10%) and high block (4%). Pain relief was assessed after the three injections by three grades: 37 (74%) had complete resolution of symptoms; 18% had partial relief and 8% did not benefit from the procedure. Conclusions: This technique may be used as an alternative technique for pain relief in patients with unilateral cervical and lumbar radiculopathies.

  • Background: Previous studies have shown that if performed without radiographic guidance, the loss of resistance (LOR) technique can result in inaccurate needle placement in up to 30% of lumbar epidural blocks. To date, no study has shown the efficacy of measuring the depth of the posterior complex (ligamentum flavum, epidural space, and posterior dura) ultrasonographically to distinguish true and false LOR. Methods: 40 cervical epidural blocks were performed using the LOR technique and confirmed by epidurograms. Transverse ultrasound images of the C6/7 area were taken before each cervical epidural block, and the distances from the skin to the posterior complex, transverse process, and supraspinous ligament were measured on each ultrasound view. The number of LOR attempts was counted, and the depth of each LOR was measured with a standard ruler. Correlation of false and true positive LOR depth with ultrasonographically measured depth was also statistically analyzed. Results: 76.5% of all cases (26 out of 34) showed false positive LOR. Concordance correlation coefficients between the measured distances on ultrasound (skin to ligamentum flavum) and actual needle depth were 0.8285 on true LOR. Depth of the true positive LOR correlated with height and weight, with a mean of $5.64{\pm}1.06cm$, while the mean depth of the false positive LOR was $4.08{\pm}1.00cm$. Conclusions: Ultrasonographic measurement of the ligamentum flavum depth (or posterior complex) preceding cervical epidural block is beneficial in excluding false LOR and increasing success rates of cervical epidural blocks.

  • Background: Cervical epidural injection, performed via the interlaminar approach, represents a useful interventional pain management procedure indicated in patients with a cervical herniated disk. Due to thedecreased epidural space in the cervical region, cervical epidural injections may result in potentially serious complications, especially during a large volume injection. Methods: Thirty-four patients with neck pain due to a cervical herniated disk that were referred to the pain clinic for cervical epidural steroid injection were randomized into two groups. One group received a cervical epidural injection of 4 ml drug and the other group received 2 ml drug. The injected mixture included triamcinolon, ropivacaine and omnipaque. Spread levels of the drug after injection were estimated with the use of C-arm fluoroscopy. Results: Spread levels to the cephalad for patients in the two groups were $4.88{\pm}0.78segments$ and $4.53{\pm}0.49segments$, respectively. Spread levels to the caudad for patients in the two groups were $4.59{\pm}0.93segments$ and $4.47{\pm}0.51segments$, respectively. The results showed no significant difference in the spread level between the two groups. Conclusions: Use of a small volume of drug (2 ml) can provide a sufficient spread level of the injected drug that is desirable for patients with a cervical herniated disk.

  • With the medical progress that has given spinal cord injured(SCI) individuals greater longevity and better overall health, chronic pain is emerged as major challenge in treating this population. According to past reports, estimates of prevalance of severe/disabling chronic pain in SCI patients have ranged from 18% to 63%. In etiologies of chronic pain in SCI patients, psychic or psychogenic pain categories should be included and more recent data have demonstrated that the persistant pain is directly related to higher levels of psychosocial distress and impairment. Recently, neurophysiological classification of the SCI pain syndrome into three etiologic groups(a; mechanical pain, b; radicular pain, c; deafferentation pain) is more frequently adopted for the classification of chronic SCI pain syndrome. The deafferentation pain is most common of the pain syndromes associated with SCI. After cervical epidural anesthesia for the surgical intervention of decubitus ulcer on the hip of two SCI patients, there were much reduction of existing chronic deafferentation character pain.
