Background: Selective transforaminal epidural block (STEB) has showen effectiveness as a diagnostic and therapeutic option for the management of patients with low back pain or sciatica. This study was carried out in order to determine the short-term effects and prognostic factors associated with STEB in patients with low back pain or sciatica. Methods: Ninety-seven patients were selectedfor participation in this study. Their diagnosis were based werewason the clinical symptoms and MRI findings. We performed STEB under fluoroscopic guidance and injected 3 ml of radio opaque dye in order to confirm the technical success of the procedure. We then injected 20 mg of triamcinolone mixed into 3 ml of 0.5% mepivacaine. One month later, we classified the patient outcomes as excellent, good, moderate or poor, according to the degree of reduction in VAS score from baseline. The independent variables assessed included symptom duration, block level, number of blocks, primary diagnosis, prior caudal block, anterior epidural space filling of dye, medication history, demographic data, radiating pain, back surgery and spondylolisthesis. Results: At a mean follow-up period of 1 month after STEB, excellent results were noted in the patients diagnosed with herniated lumbar disc (70%), non-specific spondylosis (54%), spinal stenosis (44%), and failed back syndrome (28%). The patients with epidural adhesion and combined spondylolisthesis were associated with poorer outcomes. Combined caudal block, symptom duration and the extent of epidural spread of the drug were not related to the effectiveness of the treatment. Conclusions: Selective transforaminal epidural block is effective in treating patients with radiculopathy, such as herniated lumbar disc, but it isrelatively ineffective in treating patients with structural deformities, such as failed back syndrome and spondylolisthesis.

Low back pain(LBP) is one of the most common ailment. There were two type of LBP in the clinic. One of them is low back pain with leg pain, the other one is low back pain without leg pain. Author explain the reasons, characters. mechanism, diagnosis, and reported 156 cases of LBP. There are various method to treatment of low back pain in recent. The first selection for treatment of LBP were intervertebral block added "+" type block(IVP "+" TB). according to author's experience, the rate of Excellent and good were account for 96.2%. Other method of LBPO therapy were also used in Pain clinic, such as psoas compartment block, caudal block, epidural steroid block, zygapophysial joint block, nerve root block, subarachnoid neural block, Lumbar sympathetic block, etc. Finally, author introduced Pain clinic in China. divided to three titles: (1) history, (2) CASP and scientific activity, (3) pain therapy in China.

Psoas compartment block has been used to provide anesthesia and analgesia of hip joint. This block is advocated for relief of pain of various origins in the thigh, leg and lumbar area. A-40-year-old women complained of pain in the left thigh and lumbar area after operation of the second lumbar vertebral compression fracture. To relieve pain, caudal block was performed. This block reduced in lumbar pain but left thigh pain persisted. So, we were performed psoas compartment block using mepivacaine and dexamethasone, which relieved the pain in the left thigh and lumbar area. We recommend psoas compartment block as useful and simple method for patients with thigh and lumbar area pain, especially when the epidural block is not feasible.

Epidural injection of narcotics for postoperative pain relief has been well reported. Caudal nalbuphine was assessed as a postoperative analgesic in a randomized double blind study of 80 patients after perianal surgery. Caudal block was carried out with 1.5% lidocaine 25 ml (Group 1) in 20 patients, and mixed with nalbuphine 3 mg (Group 2) in 20 patients, nalbuphine 5 mg (Group 3) in 20 patients, and nalbuphine 10 mg (Group 4) in 20 patients. Pain relief was evaluated by the subsquent need for systemic analgesics (Pethidine). In group 4, the use of systemic analgesics was significantly reduced for the first 24 hours postoperatively. Urinary retention was not correlated with nalbuphin dose.

In infants and small children, ultrasound (US) guidance provides ample anatomical information to perform neuraxial blocks. We can measure the distance from the skin to the epidural space in the US image and can refer to it during needle insertion. We may also visualize the needle or a catheter during real-time US-guided epidural catheterization. In cases where direct needle or catheter visualization is difficult, US allows predicting successful puncture and catheterization using surrogate markers, such as dura mater displacement, epidural space widening due to drug injection, or mass movement of the drug within the caudal space. Although many experienced anesthesiologists still prefer to use conventional techniques, prospective randomized controlled trials using US guidance are providing increasing evidence of its advantages. The use of US-guided regional block will gradually become widespread in infants and children.

Background: The aim of the study was to investigate the feasibility of fluoroscopy-guided anterior approach for suprascapular nerve block (SSNB). Methods: Twenty patients with chronic shoulder pain were included in the study. All of the nerve blocks were performed with patients in a supine position. Fluoroscopy was tilted medially to obtain the best view of the scapular notch (medial angle) and caudally to put the base of coracoid process and scapular spine on same line (caudal angle). SSNB was performed by introducing a 100-mm, 21-gauge needle to the scapular notch with tunnel view technique. Following negative aspiration, 1.0 ml of contrast was injected to confirm the scapular notch, and 1 % mepivacaine 2 ml was slowly injected. The success of SSNB was assessed by numerical rating scale (NRS) before and after the block. Results: The average NRS was decreased from $4.8{\pm}0.6$ to $0.6{\pm}0.5$ after the procedure (P < 0.05). The best view of the scapular notch was obtained in a medial angle of $15.1{\pm}2.2$ ($11-19^{\circ}$) and a caudal angle of $15.4{\pm}1.7^{\circ}$ ($12-18^{\circ}$). The average distance from the skin to the scapular notch was $5.8{\pm}0.6$ cm. None of the complications such as pneumothorax, intravascular injection, and hematoma formation was found except one case of partial brachial plexus block. Conclusions: SSNB by fluoroscopy-guided anterior approach is a feasible technique. The advantage of using a fluoroscopy resulted in an effective block with a small dose of local anesthetics by an accurate placement of a tip of needle in the scapular notch while avoiding pneumothorax.

Air injected into the epidural space may spread along the nerves of the paravertebral space. Depending on the location of the air, neurologic complications such as multiradicular syndrome, lumbar root compression, and even paraplegia may occur. However, cases of motor weakness caused by air bubbles after caudal epidural injection are rare. A 44-year-old female patient received a caudal epidural injection after an air-acceptance test. Four hours later, she complained of motor weakness in the right lower extremity and numbness of the S1 dermatome. Magnetic resonance imaging showed no anomalies other than an air bubble measuring 13 mm in length and 0.337 ml in volume positioned near the right S1 root. Her symptoms completely regressed within 48 hours.

We had retrospective analysis of 421 patients who were consulted from other departments. From 1994 to 1997, these patients received nerve blocks, intravenous lidocaine infusion, lasers and so on for their pain. From these results, we are gathering information and making some recommandations. The largest percentage of patients were in their fifties with a distribution of 32.8% male and 55.1% female. The most common condition requiring treatment was low back pain 44.6%, followed by cancer pain 19.2%, cervical pain 7.4%, and shoulder pain 4.3%. In case of low back pain, the largest portion was HNP(27%), followed by spinal stenosis(16%), sprain(11%), and postlaminectomy(10%). The most common cacer was colorectal(28.4%) and the next was stomach(19.7%). The most commonly done nerve block was stellate ganglion block 32.3%, followed by lumbar epidural block 24.5% and caudal block 7.2%.

Background: Immune responses appear to be affected by anesthetics and analgesics. We investigated the effects of caudal tramadol on the postoperative immune response and pain management in pediatric patients. Methods: Sixty ASA-I pediatric patients aged 3-10 years undergoing lower abdominal surgery. Patients were randomly assigned either to a caudal bupivacaine (0.25%) group (group B), or a group that received caudal tramadol (1 mg/kg) added to the bupivacaine (0.25%) (group T). Both were diluted in a 0.9% NaCl solution to a total volume of 1ml/ kg. The systemic immune response was measured by collecting blood samples preoperatively, at the end of anesthesia, and at 24 and 72 hours postoperatively, and studied for interleukin IL-6, C-reactive proteins (CRP) cortisol levels, and leucocytes with its differential count. Postoperative pain was assessed along with sedation scales. Results: Postoperative production of IL-6 was significantly higher in group B at the end of anesthesia, than at the $24^{th}$ hour, and at the $72^{nd}$ hour in group B and group T, respectively. The immune response showed leukocytosis with increased percentages of neutrophil and monocytes, and a decreased lymphocyte response rate within both groups with no significant differences between the groups. Cortisol and CRP were significantly higher in group B. Conclusions: Adding tramadol to a caudal bupivacaine block can attenuate the pro-inflammatory cytokine response, Cortisol, and CRP in children undergoing lower abdominal surgery.
