The levels of improvement in ODI, VAS for low back pain, and VAS for lower-limb pain were considerably more in patients with single-level involvement (P less then 0.001, P = 0.04, and P less then 0.001, respectively). Improvement of lower-limb VAS was negatively correlated with age (r = -0.400, P less then 0.001) and BMI (r = -0.525, P less then 0.001). The ODI improvement was also negatively correlated with BMI (r = -0.569, P less then 0.001). Conclusions Epidural injection of triamcinolone through the translaminar approach could be regarded as an efficacious method for the alleviation of pain and disability in patients with spinal canal stenosis.

The purpose of this work is to describe the actual situation of surgical patients focusing on effective pain control by discarding prejudice against 'aggressive' measures. Evidence Acquisition This is a narrative review about continuous regional pain therapy with catheters in the postoperative period. Included are the most-relevant literature as well as own experiences. Results As evidenced by an abundance of studies, continuous regional/neuraxial blocks are the most effective approach for relief of severe postoperative pain. Catheters have to be placed in adequate anatomical positions and meticulously maintained as long as they remain in situ. Peripheral catheters in interscalene, femoral, and sciatic positions are effective in patients with surgery of upper and lower limbs. Epidural catheters are effective in abdominal and thoracic surgery, birth pain, and artery occlusive disease, whereas paravertebral analgesia may be beneficial in patients with unilateral approach of the truncus. However, failure rates are high, especially for epidural catheter analgesia.
