BACKGROUND Laparoscopic cholecystectomy (LC) has traditionally been performed under general anesthesia, however, owing in part to the advancement of surgical and anesthetic techniques, many laparoscopic cholecystectomies have been successfully performed under the spinal anesthetic technique. We hoped to determine the feasibility of segmental epidural anesthesia for LC. METHODS Twelve American...

BACKGROUND Transforaminal epidural injections, or selective nerve root blocks, are used for a myriad of different spinal disorders. A clear consensus on the use of selective nerve root injections as a diagnostic tool does not currently exist. Additionally, the effectiveness of this procedure as a diagnostic tool is not clear. OBJECTIVE The objective was to evaluate the accuracy of selective n...

BACKGROUND This report describes the methodological approach and clinical application of a minimally invasive intervention to treat lumbar spinal stenosis (LSS). METHODS Thirty-four patients with LSS underwent fluoroscopically guided transforaminal epidural dry needling using a specially designed flexed Round Needle. The needle was inserted 8-12 cm lateral to the midline at the level of the s...

BACKGROUND When applying pulsed radiofrequency on dorsal root ganglia for treating chronic lower back pain, maximum efficiency can be expected when a needle is placed 1-2 cm peripheral to the dorsal root ganglion. The object of this study is to analyze images taken after adding contrast to transforaminal epidural injection, categorize root ganglia according to anatomical position, and provide a...

After a nerve block, observation of the course of effects is necessary until discharge of patients. Particularly epidural block in the lumbar region markedly affects ambulation and postural stability. Although there are few methods of objective evaluation of the postural stability, safe and early discharge is desired. We evaluated the influences of epidural block with 5 ml of 1% lidocaine on eq...

A 32-year-old parturient requested epidural analgesia for labor. A lumbar epidural block was performed at the L1-2 interspace. Thirty minutes after the loading dose of the local anesthetic mixture, she suffered numbness in both arms and high sensory block up to the C6 dermatome without significant motor blockade. The retained epidural catheter was later confirmed radiologically to be in the sub...

PURPOSE OF REVIEW To consider optimal analgesic strategies for thoracic surgical patients. RECENT FINDINGS Recent studies have consistently suggested analgesic equivalence between paravertebral and thoracic epidural analgesia. Complications appear to be significantly less common with paravertebral analgesia. SUMMARY There is good evidence that paravertebral block can provide acceptable pain...

PURPOSE Total knee replacement is one of the most painful orthopedic procedures, and effective pain relief is essential for early mobility and discharge from hospital. The aim of this study was to evaluate whether addition of single-injection femoral nerve block to epidural analgesia would provide better postoperative pain control, compared to epidural analgesia alone, after total knee replacem...
