Effect of Laryngeal Mask Airway on Image Quality n Pediatric Patients Undergoing Magnetic Resonant Imaging

National Cancer Institute, Egypt40 enrolled

Overview

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.

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.

Interventions

guedel airwayDEVICE

Anesthesia will be conducted by induction with 1-2 • Mg/kg of an IV propofol bolus and then anesthesia is maintained with an inhalational anesthesia with sevoflurane 2%-4%. The goal is to maintain the patient spontaneous ventilation throughout the procedure. Monitoring of the patients is done by MRI compatible pulse oximetry for heart rate and oxygen saturation which is connected to MRI control room.

Outcomes

Primary Outcomes

Image quality of each MRI sequence

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).

Time frame: During general anesthesia of MRI investigation procedure
