Insights
Intramuscular ketamine provided better sedation success and shorter scan times for pediatric brain MRI compared to intravenous ketamine. This method is more appealing for certain pediatric sedation needs.
Area of Science:
- Pediatric Radiology
- Anesthesiology
- Pharmacology
Background:
- Sedation is crucial for pediatric brain MRI to ensure image quality and patient safety.
- Ketamine is a commonly used sedative agent in pediatric procedural sedation.
Purpose of the Study:
- To compare the efficacy of intramuscular (IM) versus intravenous (IV) ketamine for sedation in children undergoing brain MRI.
- To evaluate sedation success rates, scan times, and procedural interruptions between IM and IV ketamine administration.
Main Methods:
- A randomized study comparing 1.5 mg/kg IV ketamine versus 4 mg/kg IM ketamine in children requiring elective brain MRI.
- All patients received supplementary midazolam intravenously prior to positioning.
- Monitoring included pulse rate, oxygen saturation (SpO2), and respiratory patterns.
Main Results:
- Intramuscular ketamine demonstrated a significantly higher success rate for sedation with the first dose compared to the IV group.
- Children receiving IM ketamine had significantly shorter scan times and lower rates of scan interruption and repeat.
- Technician satisfaction with sedation was significantly higher in the IM ketamine group (98.1%) versus the IV group (80.8%).
Conclusions:
- Intramuscular ketamine offers a superior sedative success rate and reduced scan duration compared to intravenous administration for pediatric brain MRI.
- IM ketamine is a more appealing option for sedation in specific pediatric imaging scenarios, enhancing efficiency and patient management.
Objective:
The aim: To compare efficacy of intramuscular (IM) versus intravenous (IV) ketamine for sedation in children undergoing brain MRI scanning in children.
Patients And Methods:
Materials and methods: Children who required elective brain MRI were selected for this study. They were randomly divided into two groups; group I received 1.5 mg/kg IV Ketamine and group II received 4 mg/kg IM ketamine. In each group supplementary 0.1 mg/kg midazolam intravenously before positioning on MRI table was given. Patients were monitored for pulse rate, SPO2, and respiratory wave.
Results:
Results: Children who received IM ketamine had significantly shorter scan time and a greater success rate of sedation with first dose than the IV group. The proportions of scan interruption and scan repeat were significantly higher among the IV group than in the IM group. The scan time was longer among the IV group than in the IM group with significantly more scan interruption and repeat. Satisfaction with sedation as expressed by the technicians was significantly more in the IM group than in IV group (98.1% vs. 80.8%, P= 0.004).
Conclusion:
Conclusions: Intramuscular ketamine injection was predicted to have a better sedative success rate and takes less time to complete than intravenous admin¬istration. This makes IM ketamine more appealing in certain conditions.
