Use of capnography and transcutaneous oxygen monitoring during outpatient general anesthesia for oral surgery.
The combination of the capnograph (respired CO2 monitor) and the transcutaneous oxygen monitor was evaluated as a non-invasive system for monitoring of respiratory function in 10 ASA class I patients undergoing ultralight general anesthesia for removal of third molars. Capnography proved to be a sensitive and accurate method for detecting apnea and airway obstruction using the continuous display of the CO2 waveform. All episodes of apnea or obstruction were immediately detected as the respired CO2 level fell to zero baseline. ⋯ During steady-state conditions of respiration, transcutaneous oxygen tensions (PtcO2) correlated well with simultaneously measured PaO2 (r = 0.93). However, during any period when oxygenation was rapidly changing (step increase in FIO2, step decrease in FIO2, or apnea) the PtcO2 lagged behind changes in PaO2 even after a five-minute equilibration period, thereby not accurately reflecting the true state of oxygenation. Consequently, the transcutaneous oxygen monitor does not appear to be optimal as a respiratory monitor in the setting of ultralight general anesthesia where rapid, critical changes in oxygenation must be detected without delay.

Case ReportsLife-threatening sublingual hematoma in a severely hemophilic patient with factor VIII inhibitor.
The management of a patient with Factor VIII inhibitor in whom a marked hematoma of the sublingual region developed is described. Administration of activated prothrombin complex concentrates and nasotracheal intubation with the fiberoptic laryngoscopy were used in the management of this patient.

Prevention of complications associated with intravenous sedation and general anesthesia.
An analysis of three time phases--induction, maintenance, and recovery from anesthesia--is presented to clarify specific risk situations and the treatment necessary to decrease morbidity and mortality in the dental office.

Case ReportsPneumomediastinum and subcutaneous cervical emphysema during third molar extraction under general anesthesia.
A case of pneumomediastinum and subcutaneous cervical emphysema during the extraction of third molars under general anesthesia has been presented. The most likely cause was pulmonary barotrauma secondary to a faulty expiratory valve. This emphasizes the need for the proper preoperative check of all anesthetic equipment. Although pneumomediastinum and subcutaneous cervical emphysema are usually self-limiting conditions with rapid recovery, the patient must undergo close observation for the possible development of serious complications.

Case ReportsSimultaneous occurrence of dermoid and heterotopic intestinal cysts in the floor of the mouth of a newborn.
Congenital cysts of the floor of the mouth are rare. The simultaneous appearance in a newborn of two different types of epithelial-lined cysts is reported. It is the first such case to be reported in the literature.
