Pulse oximetry during minor oral surgery with and without intravenous sedation.
This study investigated the levels of oxygen saturation and pulse rates of patients undergoing minor oral surgery under local analgesia, with (20 patients) or without (20 patients) intravenous sedation with midazolam. The results indicated that a statistically significant fall in arterial blood oxygenation of 1% to 2%, as measured by pulse oximetry, followed midazolam administration; however, this was physiologically insignificant. ⋯ Midazolam had a small but significant calming effect on the higher preoperative pulse rates exhibited by anxious patients, but this effect was not sustained during the operating period. Both sedated and unsedated patients showed episodes of tachycardia that could have significance for patients with cardiac disease.

Clinical symptoms of open lock position of the condyle. Relation to anterior dislocation of the temporomandibular joint.
Nine cases of open lock position of the condyle of the temporomandibular joint (TMJ) are reported. In two patients recurrent dislocation of the TMJ was diagnosed clinically, and four had previous episodes of anterior dislocation. ⋯ One cause of anterior dislocation of the TMJ is thought to be fixation of the condyle in the open lock position resulting from a disturbance of a neuromuscular mechanism. In the two patients with dislocation, occlusal treatment eliminated muscular symptoms and the dislocations completely disappeared.

Case ReportsMediastinitis caused by odontogenic infection associated with adult respiratory distress syndrome.
A case of descending mediastinitis resulting from dental infection and complicated by adult respiratory distress syndrome (ARDS) is reported. The patient had a long history of heavy drinking. ⋯ The cause of ARDS appeared to be aspiration pneumonia. It is extremely rare for oral and maxillofacial surgeons to encounter a patient with ARDS.

Randomized Controlled Trial Clinical TrialEfficacy of chlorhexidine and nystatin rinses in prevention of oral complications in leukemia and bone marrow transplantation.
The goal of reducing oral complications during chemotherapy and bone marrow transplantation has received attention at several centers. The current randomized study of 86 adults with leukemia treated with chemotherapy or bone marrow transplantation assessed the potential role of chlorhexidine, nystatin, and saline solution rinses to reduce the findings of oral mucositis, gingivitis, and oral infection. The results of this study did not show a reduction in mucositis with the use of these rinses. However, potential bacterial and fungal pathogens were identified less frequently in the patients using chlorhexidine rinse.
