ReviewUtilization and mechanism of action of tricyclic antidepressants in the treatment of chronic facial pain: a review of the literature.
Tricyclic antidepressants show promise in the treatment of chronic facial pain. The antinociceptive activity of this class of drugs appears to be independent of any antidepressant effects. ⋯ This antinociceptive pathway appears to utilize an endogenous pain modulation system. Future studies may demonstrate the operative mechanisms of action and open understanding as to etiologic factors.

Comparative StudyEvaluation of the accuracy of non-invasive automatic blood pressure monitors.
Non-invasive automatic blood pressure monitors (BP-103N, DINAMAP 845XT, Finapres 2300) were compared with the auscultatory method. The blood pressure readings given by the oscillometric method (BP-103N, DINAMAP 845XT) were accurate and reproducible. ⋯ For diastolic pressure readings, there was less agreement with the results of the auscultatory method. The finger arterial pressure method (Finapres 2300) occasionally displayed greater variability than the devices using the oscillometric method.

Five patients requiring general anesthesia but presenting with compromised airways were successfully intubated by blind awake intubation with the aid of regional anesthesia and the use of appropriate sedation. Arterial blood gases were collected at three intervals: presedation, postsedation, and postintubation. ⋯ Supplemental oxygen is suggested to avoid the effects of arterial desaturation during the sedation process. If oxygen is not administered, the risk of moderate hypoxia associated with blind awake intubation must be considered along with alternative problems including loss of protective reflexes or the inability to ventilate during induction and intubation via a direct technique.

End tidal carbon dioxide and respiratory rate measurement during conscious sedation through a nasal cannula.
During the administration of central nervous system depressant drugs for dentistry or surgery, it may not always be possible to continuously measure respiratory physiology. We present a simple and efficacious method of monitoring respiration during dental or surgical procedures in which a conscious sedation technique is used.
