Effect of subarachnoid gabapentin on tactile-evoked allodynia in a surgically induced neuropathic pain model in the rat.
Spinal gamma-aminobutyric acid (GABA) receptors have been shown to modulate post-nerve injury-induced allodynia. This study sought to examine the antiallodynic effects of a GABA analog gabapentin [1-(aminomethyl)cyclohexaneacetic acid], given by subarachnoid injection in a rat neuropathic pain model. ⋯ Gabapentin shows antiallodynic effect, but its mechanism is not known. The failure to reverse this effect by GABA A or B antagonists at doses that reverse the effects of the respective agonists suggests that gabapentin is involved in the modulation of spinal systems by mechanisms that do not involve either a GABA A or a GABA B site.

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.

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.

Clinical TrialSingle-injection lumbar epidural morphine for postoperative analgesia in children: a report of 175 cases.
Since the first report of epidural opioid administration to pediatric patients, several studies have described the quality of analgesia, doses, pharmacokinetics, and side effects of this procedure. A pediatric series using an easy and cheap single-injection technique of epidural morphine administration for postoperative analgesia is presented. ⋯ This technique is easy to perform, even for trainees in anesthesiology. With appropriate patient selection and avoidance of the concomitant use of narcotics and sedatives, epidural morphine provides prompt, effective, safe, and prolonged analgesia in children.
