The success of the neurolytic celiac plexus block, despite different approaches and methods used, depends on adequate spread of the injectate in the celiac area. This retrospective study was conducted to evaluate the patterns of alcohol spread and pain relief in patients with cancer or therapy-related anatomic distortion of the celiac area. ⋯ These findings suggest that, using the single-needle anterior approach, the neurolytic spread in the celiac area is highly hampered by the regional anatomic alterations. It also appears that only a complete (four quadrants) neurolytic spread in the celiac area can guarantee long-lasting analgesia, and that this picture may be obtained in a very limited fraction of patients with regional anatomic alterations.

Clinical Trial Controlled Clinical Trial
The addition of interscalene block to general anesthesia for patients undergoing open shoulder procedures.
Several studies have demonstrated that interscalene brachial plexus anesthesia alone decreases postoperative pain, nausea, vomiting, urinary retention, and unplanned hospital admissions compared with general anesthesia alone. Anecdotal evidence suggests that an interscalene block combined with general anesthesia decreases unwanted effects of general anesthesia following open shoulder surgery. We compared the effect of combined interscalene block and general anesthesia with general anesthesia alone on Aldrete scores, length of postanesthesia care unit (PACU) stay, verbal rating scale (VRS) pain scores, incidence of postoperative narcotic administration and nausea, and patient satisfaction in a convenience sample of 52 men and women, ASA physical status I, II, or III. ⋯ Group 2 had significantly lower VRS scores than group 1 while in the PACU, on the day of surgery, and on postoperative days 1 and 2. Overall satisfaction with the anesthetic technique was higher in the group 2 than in group 1. Results suggest that adding an interscalene block to general anesthesia can be of value in today's outpatient-dominated surgery schedule.

Case Reports
A cervical anterior spinal artery syndrome after diagnostic blockade of the right C6-nerve root.
A 48-year-old man suffered from intractable neck pain irradiating to his right arm. Magnetic resonance imaging (MRI) of the cervical spine was unremarkable. ⋯ Immediately following this seemingly uneventful procedure he developed a MRI-proven fatal cervical spinal cord infarction. We describe the blood supply of the cervical spinal cord and suggest that this infarction resulted from an impaired perfusion of the major feeding anterior radicular artery of the spinal cord, after local injection of iotrolan, bupivacaine, and triamcinolon-hexacetonide around the C6-nerve root on the right side.

Thirty unpremedicated ASA physical status 1-3 patients aged between 18 and 69 years, scheduled for upper limb surgery, received a conventional supraclavicular brachial plexus block using a nerve stimulator and bupivacaine 0.375% 0.5 ml.kg-1. Spirometric measurements of pulmonary function and ultrasonographic assessments of diaphragmatic function were made before the block and at 10-min intervals after injection until full motor block of the brachial plexus had developed. ⋯ Those with complete paralysis all showed significant decreases in pulmonary function, whereas those with reduced or normal movement had minimal change. All patients remained asymptomatic throughout, with normal oxygen saturation on room air.
