Comparison of the effects of remifentanil andalfentanil on cardiovascular response to nasotracheal intubation: A prospective, randomized, double-blind study.
Nasotracheal intubation is often necessary in patients undergoingelective or emergency maxillofacial surgery. Previous studies have suggested that the increase in blood pressure after nasotracheal intubation is significantly greater than the increase after orotracheal intubation. Many drugs, including narcotic analgesics, are effective in modifying cardiovascular responses to orotracheal intubation. ⋯ In this study in healthy surgical patients aged 16 to 65 years, remifentanil 1 μg/kg given over 30 seconds, followed by a remifentanil infusion of 0.5 μg/kg · min, was similarly effective compared with alfentanil 10 μg/kg in attenuating the pressor response to nasotracheal intubation, but the incidence of hypotension in patients administered remifentanil was high.

Effects of intravitreal ropivacaine on retinal thickness and integrity in the guinea pig.
Retrobulbar anesthesia is widely used for ocular surgery.Ocular complications are possible when retrobulbar anesthesia is accidentally injected intravitreally. ⋯ In this small experimental study, ropivacaine had concentration-dependent toxic effects on guinea pig retinas.

Effects of diazepam on diaphragmatic functionand recovery in pentobarbital-anesthetized dogs: An open-label, dose-finding, pharmacologic study.
Diazepam, a highly lipid-soluble benzodiazepine, is commonly used as a sedative agent during and after surgery. Based on a literature search, no published data are available concerning diaphragmatic function (as measured by contractility and electrical activity) during and after the administration of diazepam. ⋯ The results of this experimental study of the effects of diazepamon diaphragmatic function and recovery in pentobarbital-anesthetized dogs suggest that diazepam inhibits diaphragmatic function in a dose-related manner and delays recovery.

Levetiracetam in the preventive treatmentof transformed migraine: A prospective, open-label, pilot study.
Most preventive agents used for transformed migraine (TM)have not been studied specifically for the treatment of this syndrome. Open-label trials have demonstrated the effectiveness of levetiracetam in the treatment of refractory headaches. ⋯ The results of this study in patients with TM support the role of levetiracetam in the preventive treatment of refractory TM.

Effectiveness and tolerability of once-daily nimesulide versus ibuprofen in pain management after surgical extraction of an impacted third molar: A 24-hour, double-blind, randomized, double-dummy, parallel-group study.
Nimesulide is a nonsteroidal, anti-inflammatory drug that hasbeen used for a wide range of acute and chronic pain. A once-daily formulation of nimesulide is now commercially available, but its effectiveness in pain management after dental surgery has not been assessed. ⋯ In this study of patients with moderate to severe pain afterextraction of impacted third molars, nimesulide and ibuprofen provided effective 24-hour relief. However, the results suggest that the analgesic effect of nimesulide had a faster onset (<15 minutes) and was stronger (based on patient opinion) than that of ibuprofen. Both study drugs were well tolerated.
