Randomized Controlled Trial Comparative Study Clinical TrialA comparison of the effects of EMLA cream and topical 5% lidocaine on discomfort during gingival probing.
This investigation compared the use of a 5% eutectic mixture of local anesthetics (EMLA) cream to a "standard" intraoral topical anesthetic (5% lidocaine) as a means of anesthetizing the gingival sulcus in a double-blind, split-mouth study with human volunteers. A 5-min application of EMLA in a customized intraoral splint resulted in a significant increase in the depth of probing of the gingival sulcus without discomfort compared to a similar application of 5% lidocaine. Following application of EMLA, the pain-free probing depth measured at three sites in the upper premolar region increased by a mean total of 2.8 mm compared to an increase of 1.9 mm with lidocaine. This study suggests EMLA may be advantageous in providing periodontal anesthesia where manipulation of the gingiva is necessary.

Review Case ReportsAsystole and bradycardia during maxillofacial surgery.
A Chinese female undergoing maxillary osteotomy developed asystole when the maxillary tuberosity was cut. Surgery was stopped. ⋯ Atropine was administered intravenously, resulting in an increase in heart rate. No further episodes of asystole or bradycardia were encountered.

Comparative StudyRespiratory effects of a balanced anesthetic technique--revisited fifteen years later.
Five hundred and fifty patients underwent general anesthesia with fentanyl, diazepam, and methohexital. Forty-seven (8.5%) developed signs of hypoventilation or airway obstruction. Arterial blood gas analysis revealed mild hypoxemia in three of the 47 cases and mild hypercarbia in six. Airway obstruction was more predictive of abnormal blood gas values than was hypoventilation.

Case ReportsPulse oximetry signals local anesthetic-induced methemoglobinemia.
An otherwise healthy patient with a fractured mandible was scheduled to undergo an open reduction under general anesthesia. Just before transport to the operating room, bimaxillary arch bars were placed under local anesthesia with 4% prilocaine and 1:200,000 epinephrine. ⋯ A total of 150 mg of methylene blue administered in two doses corrected the problem. The oral surgeon, having recently switched to prilocaine because of a manufacturer's recall of lidocaine, was unaware of the potential of prilocaine to cause this disorder.
