Randomized Controlled Trial Comparative Study Clinical TrialUse of preincisional ketorolac in hernia patients: intravenous versus surgical site.
This study was designed to determine whether administration of ketorolac directly in the surgical site results in enhanced analgesia. ⋯ Ketorolac provides enhanced patient comfort when it is administered in the surgical site in patients undergoing inguinal hernia repair. It is recommended that clinicians add ketorolac to the local anesthetic solution in such patients.

Randomized Controlled Trial Comparative Study Clinical TrialThe effect of head-down tilt position on arterial blood pressure after spinal anesthesia for cesarean delivery.
The effect of the head-down tilt position after induction of spinal anesthesia for cesarean delivery on blood pressure and level of sensory block was examined. ⋯ The head-down position is concluded to have no effect on the incidence of hypotension during spinal anesthesia for cesarean delivery.

Case ReportsThermal grill illusion and complex regional pain syndrome type I (reflex sympathetic dystrophy).
In normal humans, placing a hand on a thermal grill containing warm elements separated by cool ones produces a burning sensation. In this case report, responses to a thermal grill in a patient with neuropathic pain were examined. ⋯ The thermal grill may be a useful a tool to help understand the pathophysiology of complex regional pain syndrome type I.

Comparative StudyComparison of accuracy and cost of disposable, nonmechanical pumps used for epidural infusions.
Temporary epidural catheter pumps are used to infuse analgesics in patients with chronic intractable pain. Three brands of disposable, nonmechanical pumps adapted for epidural infusion were tested to determine their flow rate efficacy and their cost effectiveness. ⋯ All three units deviated considerably from the claimed flow rate of 2-mL/h, both at the beginning and at the end of the infusion. Presumably, the decreasing flow rates are responsible for the diminishing pain relief often experienced by patients over the course of the infusion. The Homepump unit appeared to be the most cost-effective and the easiest to handle and maintained an acceptable infusion rate for the greatest percentage of the infusion period. The considerable cost benefit of using a nonmechanical disposable pump as opposed to a costly but more reliable computerized pump appears to warrant further product improvement and development.

Biography Historical ArticleEmery A. Rovenstine and regional anesthesia.
Emery Andrew Rovenstine was a dominant figure in anesthesiology in the United States between 1935 and 1960. Among his many contributions to the specialty, his regional anesthesia practice remains less well known. This paper explores Rovenstine's career and his contributions to regional anesthesia. ⋯ Emery A. Rovenstine did much to popularize regional anesthesia and ensure a rightful place for its techniques within the armamentarium of the anesthesiologist. Keeping alive the traditions of Gaston Labat at Bellevue, Rovenstine's contributions to regional anesthesia on all levels were considerable. Most importantly, he ensured an enduring role for regional anesthesia through the recurring contributions of his pupils.
