Description
Study Objective: To evaluate the effectiveness of the CTrach Laryngeal Mask Airway (LMA) when used electively. Design: Retrospective analysis. Setting: Operating room of an academic hospital. Measurements: Data from 126 patients who were electively intubated with the CTrach LMA over a 16-month period were reviewed. Each patient's weight, height, ASA physical status classification, Mallampati score, thyromental distance, and cervical spine range of motion were recorded. Main Results: Successful ventilation was achieved in 100% of patients, while successful intubation was achieved in 89.7% of patients. The most common reason for failure to intubate was poor airway visualization and the inability to appropriately position the device anterior to the vocal cords. Conclusions: The major advantage of the CTrach LMA is that it is the only device that allows airway visualization during patient ventilation; however, it does not have 100% success with intubation.

Description
STUDY OBJECTIVE: To compare the analgesic and anxiolytic effects of nitrous oxide (N2O) when inhaled by face mask with those of a cutaneous application of a eutectic mixture of local anesthetics (EMLA) cream with lidocaine and prilocaine during pre-operative venous cannulation in children. DESIGN: Prospective, randomized study. SETTING: Outpatient presurgical area and operating rooms of a freestanding children's hospital. PATIENTS: 50 unpremedicated ASA status I and II outpatients, aged 6 to 12 years, undergoing an elective surgical procedure. INTERVENTIONS: Each patient received either 70% N2O in 30% oxygen (O2) administered by face mask for 120 seconds or an application of 2.5 g of EMLA cream under an occlusive dressing for a minimum of 60 minutes. All patients then underwent a single attempt at venous cannulation in the dorsum of the hand with a
