简要总结
This study compare the effects of Oral airway vs LMA in preventing anesthesia-induced partial airway obstruction, in an attempt to lessen MRI motion artifacts, which would result in improvements in image quality.
详细描述
Magnetic resonance image (MRI) is a frequently used imaging technique especially in oncological patients, where it is used for diagnosis, following up response to treatment and later for detection of possible recurrence. The main problem encountered with MRI is the long time required for completion of the imaging, during which the patient is required to lie still. Patients who are unable to lie still require sedation or general anesthesia (GA). Almost all pediatric patients are uncooperative, making GA, the standard of care for pediatric MRI.
Several general anesthetic techniques including airway management by endotracheal tube & various supraglottic devices (LMA) have been described. Choice of technique by anesthesiologist is influenced by the patient's age, craniofacial and airway anatomy, procedure duration, & illness acuity.

结局指标
主要结局
Image quality of each MRI sequence
时间窗: During general anesthesia of MRI investigation procedure
Image quality of each MRI sequence is evaluated by using a scoring system with the following scores: score of 1 (non-diagnostic), score of 2 (poor quality but some diagnostic value), score of 3 (average), score of 4 (good), and score of 5 (excellent).
