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.

Randomized Controlled Trial Comparative Study Clinical TrialEffective postoperative pain prevention through administration of bupivacaine and diclofenac.
The efficacies of bupivacaine and lidocaine together with a preoperatively administered single-dose oral combination of normal- and sustained-release preparations of diclofenac in preventing postoperative pain after third molar removal were compared in a double-blind crossover study. Bilaterally impacted lower third molars were removed in two sessions. Each patient was given one type of local anesthetic on one session and the other in the second. ⋯ When the diclofenac combination (150 mg) was given before the operation, postoperative analgesia was better with bupivacaine plus diclofenac than with lidocaine plus diclofenac. Twenty-five out of 40 patients preferred bupivacaine to lidocaine for local anesthesia. It is possible to achieve effective postoperative pain prevention by combining bupivacaine and preoperative normal- and sustained-release preparations of diclofenac.

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.
