Introduction:
Sedation is frequently necessary for children 1to 7 years of age undergoing magnetic resonance imaging (MRI) to ensure examinations that are of diagnostic quality(1). The success of sedation for MRI has typically been measured by two factors: the safety of sedation procedure (lack of adverse events) and effectiveness of procedure (successful completion of the diagnostic examination) (2).
Sedation of children for MRI is usually associated with inadequate or failed sedation because of difficulties in having patients motionless while maintaining hemodynamic and respiratory stability. Also, limited access to the patient may pose a safety risk during MRI examination (2,3,4).Therefore, appropriate drugs need to be selected ,administered,

The aim of this prospective study was to compare the sedative, cardio respiratory effects and recovery characteristics of sevoflurane using strapped face mask with propofol infusion for sedation of children undergoing MRI …show more content…
h-1 in group P and increase the concentration of sevoflurane to1.5% - 2% in group S.

Intervention was considered necessary if SPO2 < 94%, EtCO2 > 45 mmHg, apnea (cessation of spontaneous respiration for 20 seconds), significant bradycardia or significant arrhythmia. In case of apnea or suspected airway obstruction, the MRI examination was interrupted, the patient was taken out of MRI unit and the airway patency was assessed.
When the scan completed, propofol infusion or sevoflurane inhalation was discontinued; the child is then transferred to the post anesthesia care unit (PACU) while breathing supplemental oxygen by face mask and monitored by pulse oximetry. After recovery from anesthesia, the child was transferred from PACU to the ambulatory unit (modified Aldret score ≥8 /10) .
