Background:
Magnetic resonance imaging (MRI) is gaining ground over other investigations particular in study of brain and soft tissues. The MRI procedure is painless but requires an immobile patient for a successful study. Children are required to be sedated or anesthetized for this procedure. We compared two inhalational anesthetics, namely sevoflurane and isoflurane, for the recovery profile of each with aim to determine the ideal drug for early discharge of children.
Patient And Methods:
100 patients aged 3 yrs to 10 yrs (ASA I and II) were divided into Group S (Sevoflurane), Group I (Isoflurane). The induction time, duration of the MRI study, recovery and discharge times were recorded. The data were subjected to Students t-test and Levene's test for equal variance.
Results:
In Group S, 27 male and 23 female were enrolled in comparison to 30 male and 20 female in Group 1. The induction time in Group S resulted in a mean of 133.7 seconds +/- 19.32), Group I yielded a mean of 157.44 seconds (+/- 24.20) p > 0.05). The mean recovery time with Group S was 124.4 seconds (+/- 31.57) when compared with Group I a mean of 376.46 seconds (+/- 58.20) p < 0.05. The mean discharge time in Group S was 25.20 minutes (+/- 5.71) in comparison to a mean of 37.40 minutes (+/- 7.43) p < 0.05 in Group I.
Conclusion:
Sevoflurane can be an ideal inhalational anesthetic for Volatile Induction and Maintenance Anesthesia (VIMA) in children under going daycase MRI examinations.
Insights
Sevoflurane offers faster recovery and earlier discharge for pediatric MRI scans compared to isoflurane. This makes sevoflurane an ideal anesthetic for children undergoing daycase magnetic resonance imaging (MRI) procedures.
Area of Science:
- Anesthesiology
- Pediatric Imaging
- Radiology
Background:
- Magnetic resonance imaging (MRI) is crucial for soft tissue and brain studies.
- Pediatric MRI requires patient immobility, often necessitating sedation or anesthesia.
- Comparing sevoflurane and isoflurane for pediatric anesthesia in MRI.
Purpose of the Study:
- To compare the recovery profiles of sevoflurane and isoflurane in children undergoing MRI.
- To determine the optimal anesthetic for early discharge in pediatric MRI patients.
Main Methods:
- 100 pediatric patients (3-10 years, ASA I-II) were divided into sevoflurane (Group S) and isoflurane (Group I) groups.
- Recorded induction time, MRI duration, recovery time, and discharge time.
- Statistical analysis included Student's t-test and Levene's test.
Main Results:
- Sevoflurane group (Group S) showed significantly faster mean recovery time (124.4s) compared to isoflurane (Group I, 376.46s) (p < 0.05).
- Mean discharge time was shorter for sevoflurane (25.20 min) versus isoflurane (37.40 min) (p < 0.05).
- Induction times were comparable between groups (p > 0.05).
Conclusions:
- Sevoflurane is a suitable anesthetic for pediatric daycase MRI.
- Sevoflurane facilitates faster recovery and earlier discharge compared to isoflurane.
- Supports the use of sevoflurane for Volatile Induction and Maintenance Anesthesia (VIMA) in pediatric MRI.
