About

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.

Full description

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.

Enrollment: 40 patients

---

40 participants in 2 patient groups

Control group

Active Comparator group

Description:

Treatment:

Drug: propofol bolus and then anesthesia sevoflurane

Device: guedel airway

supraglottic group

Active Comparator group

Description:

20 patients in which supraglottic airway laryngeal mask airway (LMA) will be used and then connected to anesthesia breathing circuit of MRI compatible anesthesia machine for maintenance of anesthesia of O2 and sevoflurane 2-4% .

Treatment:

Drug: propofol bolus and then anesthesia sevoflurane

Device: supraglottic airway
