Case ReportsAsymptomatic profound oxyhemoglobin desaturation following interscalene block in a geriatric patient.
Interscalene block can be chosen for complete anesthesia for shoulder surgery. Phrenic nerve block occurs with almost all interscalene blocks, but is well tolerated in most patients. This may not be the case in selected geriatric patients. ⋯ Ipsilateral phrenic nerve paralysis caused significant respiratory compromise in an elderly patient without known significant pulmonary disease.

Does spinal anesthesia affect cerebral oxygenation during transurethral prostatectomy?
Transurethral resection of the prostate (TURP) is associated with the unique complication of transurethral resection of prostate syndrome (TURS), which is attributed to the absorption of irrigating fluid. This study was initiated to investigate the effects of spinal anesthesia and TURP on cerebral oxygen balance. ⋯ The neurologic symptoms in patients undergoing TURP during spinal anesthesia might not only be caused by absorption of irrigating fluid but also by impairment of cerebral oxygenation.

Case ReportsInguinal paravascular (lumbar plexus) neurolytic block--description of a catheter technique: case report.
We provided care for a 47-year-old female with a history of lung carcinoma and bony metastases who sustained a pathologic fracture of the right acetabulum causing severe and uncontrolled pain in the right groin. Her pain was rated as 8-10 on a 10-point visual analog scale (VAS). Her terminal disease and poor surgical risk precluded therapeutic operative intervention. Consequently, a neurolytic block of the lumbar plexus was performed as a palliative measure. ⋯ This case report supports the feasibility of placing a catheter via a modified anterior inguinal paravascular block technique and its subsequent use for both local anesthetic infusion and neurolytic block of the lumbar plexus.

Intrafascicular injection of ammonium sulfate and bupivacaine in peripheral nerves of neonatal and juvenile rats.
Regional nerve blocks are often used for the treatment of postoperative pain in children. Ammonium sulfate is a non-narcotic anesthetic agent, which has been reported to provide pain relief lasting days to weeks, with few reported side effects in adult studies. Prior to considering clinical use in children, the neurotoxicity of ammonium sulfate in 4-day and 3-week old rats was assessed and compared with that of bupivacaine. ⋯ Intrafascicular injection of ammonium sulfate was as safe as bupivacaine in this animal model. Further animal studies must be made before human trials are initiated.
