BACKGROUND Patient safety has been gained much more attention in recent years. The authors reviewed patients who had cardiac arrest in the operating rooms undergoing noncardiac surgery between January 1989 and December 2001 at the University of Pittsburgh Medical Center, USA. The main objectives of the study were to determine the incidence of intraoperative(More)
BACKGROUND Understanding the mechanism of trigeminal neuralgia may be elucidated by developing laboratory animal models that closely mimic the features of this specific type of neuropathic pain. We have developed an experimental animal model for trigeminal neuralgia using a technique of injecting cobra venom into the infraorbital nerve (ION) trunk. (More)
Correspondence To the Editor: A 54‑year‑old woman with no significant history of a headache or hypertension underwent epidural oxygen‑ozone injection at a concentration of 30 μg/ml (3 ml) for cervical disc herniation at cervical vertebra (C6–C7) level. Throughout the procedure, the routine monitorings of blood pressure, heart rate, and blood oxygen(More)
BACKGROUND Spinal epidural hematoma (SEH) is a rare but acute and possibly devastating clinical event. The purpose of this study is to assess the multiple etiologies of SEH seen in an academic medical center over a 15-year span. We have examined the etiologies of SEH occurring in a single institution, the University of Pittsburgh Medical Center (UPMC) over(More)
OBJECTIVES Electroconvulsive therapy (ECT) has dramatically reduced musculoskeletal complications when carried out with muscle relaxants under general anesthesia. However, seizure quality can be affected by the depth of anesthesia and choice of anesthetic agent. The purpose of this study was to describe a general anesthetic technique for ECT by using(More)
BACKGROUND Ambient aerosol fine particulate matter (PM2.5) is associated with male reproductive toxicity in experiments and may have adverse effects in the female. However, studies evaluating the protective effects and precise mechanisms of aspirin, Vitamin C, Vitamin E, or ozone against toxic effects of PM2.5are sparse. This study was conducted to(More)
OBJECTIVE To observe the hemodynamic changes, recovery profiles, and side effects of propofol and remifentanil anesthesia by target controlled infusion (TCI). At different neurosurgical stages in patients undergoing neurosurgical operations. METHODS 230 patients were scheduled for elective craniotomy in five hospitals in Beijing, Changsha, and Guangzhou.(More)
BACKGROUND Neuropathic pain is induced by injury or disease of the nervous system. Most studies have so far focused only on a few known molecules and signaling pathways among neurons. However, all signal transmissions involved in neuropathic pain appear to be an integral system at different molecular levels. This study was designed to screen the(More)
