Randomized Controlled Trial Clinical TrialThe peripheral analgesic effect of meperidine in reducing propofol injection pain is not naloxone-reversible.
Meperidine is frequently used in general anesthesia and perioperative analgesia. In addition to its opioid action, meperidine possesses some local anesthetic properties. A preliminary study using the tourniquet venous retention technique found meperidine to be more effective in reducing propofol injection pain than fentanyl or morphine, both of which were slightly better than placebo. This study was undertaken to evaluate whether this peripheral analgesic effect of meperidine is affected by naloxone. ⋯ The peripheral analgesic effect of meperidine in reducing propofol injection pain is not mediated by its opioid activity.

Case ReportsPerisciatic injection of steroid for the treatment of sciatica due to piriformis syndrome.
Piriformis syndrome causing sciatica is sometimes refractory to conventional treatments including physical therapy, piriformis injections, and even caudal epidural steroid injections. Surgical release of the piriformis muscle has been described for difficult cases of piriformis syndrome, but is occasionally accompanied by morbidity. Another approach to treating piriformis syndrome is presented. ⋯ Patients with piriformis syndrome who were refractory to conventional treatments but responded to perisciatic injections of steroid are presented.

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.
