The effect of education and clinical practice on knowledge enlightenment to and attitudes toward the use of analgesics for cancer pain among physicians and medical students.
Insufficient education and limited clinical practice on the part of physicians may contribute to the undertreatment of cancer pain in Taiwan. To address these concerns, a survey among physicians and fifth-year medical students relevant to cancer pain management (CPM) was carried out in a medical school and its principal teaching hospital. ⋯ The effect of accumulation of clinical experience and seniority of clinical practice on CPM was limited among general physicians, except for clinical specialty on anesthesiology, hematology-oncology, or radiation oncology. In Taiwan, the knowledge of and positive attitude toward CPM could only be conveyed to physicians through undergraduate, post graduate or on-job education.

The antinociceptive effect of a long-acting nalbuphine preparation in rabbits.
An analgesic with a long-lasting effect is particularly desirable to patients suffering from long-standing pain. The aim of this study was to evaluate the antinociceptive effect and duration of action of an oily dosage form of nalbuphine base and to see whether its effect could last longer compared with nalbuphine HCl. ⋯ We conclude that intramuscular nalbuphine base produced a relatively longer duration of action than did intramuscular nalbuphine HCl.

Nitrous oxide suppresses tonic and phasic nociceptive behaviors but not formalin-induced c-Fos expression in the rat spinal cord dorsal horn.
The aim of this study was to investigate the anesthetic and analgesic effects of subanesthetic concentration of nitrous oxide and to compare these effects with halothane and fentanyl. ⋯ These findings suggest that, at the spinal level, subanesthetic concentration of nitrous oxide greatly attenuates nociceptive behaviors mainly due to a non-selective suppression of behavioral responses that are commonly associated with inhalation anesthetic drugs.

Randomized Controlled Trial Comparative Study Clinical TrialSpinal anesthesia with two different dosages of 0.75% glucose-free ropivacaine: a comparison of efficacy and safety in Chinese parturients undergoing cesarean section.
We compared the clinical efficacy and safety between 2 doses of 2.5 ml (18.75 mg) and 3 ml (22.5 mg) of 0.75% glucose free spinal ropivacaine in Chinese parturients undergoing Cesarean section. ⋯ We conclude that for Cesarean section in Chinese parturients either 18.75 mg (2.5 ml) or 22.5 mg (3 ml) 0.75% glucose-free ropivacaine can provide a spinal anesthesia of the same efficacy and safety.

Case ReportsUnusual cause of esophageal perforation during intraoperative transesophageal echocardiography monitoring for cardiac surgery--a case report.
Although esophageal perforation after transesophageal echocardiographic (TEE) examination is rare yet the occurrence of this life-threatening complication is increasing. We report an unusual esophageal perforation occurring 4 days after coronary artery bypass graft surgery and Bentall's procedure. The perforation was due to inadvertent injury of the esophagus that was deformed and distorted by a large calcified lymph node in the mediastinum during intraoperative TEE instrumentation. We suggest that careful preoperative radiological examination of the mediastinum should be done to recognize the anatomical pathology in patient whose routine chest X-ray has disclosed a large calcified lymph node in the mediastinum, if he happens to undergo TEE, so as to avoid disastrous esophageal perforation.
