Insights
This study found that a propofol-ketamine mixture is a safe anesthetic for pediatric cardiac catheterization. The combination provided effective anesthesia with minimal complications in young patients.
Area of Science:
- Anesthesiology
- Pediatric Cardiology
- Pharmacology
Background:
- General anesthesia is crucial for pediatric cardiac catheterization.
- Propofol and ketamine are commonly used anesthetics.
- Evaluating combined anesthetic safety is essential for pediatric procedures.
Purpose of the Study:
- To assess the safety and efficacy of a propofol-ketamine mixture for inducing and maintaining anesthesia.
- To evaluate the anesthetic's impact on spontaneously breathing pediatric patients during cardiac catheterization.
Main Methods:
- Prospective clinical study involving 45 pediatric patients (6 months to 16 years).
- Continuous intravenous infusion of propofol (4 mg/mL) and ketamine (2 mg/mL) mixture.
- Monitoring of hemodynamic, respiratory, and recovery variables.
Main Results:
- Mean ketamine dose: 26 +/- 8.3 microg/kg/min; propofol dose: 68.3 +/- 21.7 microg/kg/min.
- Minor hemodynamic changes (heart rate, mean arterial pressure) in a few patients.
- Transient hypoventilation in 3 patients, successfully managed with oxygen and ventilation support; no other complications.
Conclusions:
- Propofol-ketamine mixture is a safe and practical anesthetic option.
- Suitable for general anesthesia in pediatric patients undergoing cardiac catheterization.
- Demonstrates a favorable safety profile with effective anesthesia delivery.
Objective:
To evaluate the safety of a propofol-ketamine mixture to induce and maintain anesthesia in spontaneously breathing pediatric patents during cardiac catheterization.
Design:
Prospective clinical study.
Setting:
Departments of Cardiothoracic Surgery, Anesthesiology, and Pediatric Anesthesiology in a university hospital.
Participants:
Forty-five children aged 6 months to 16 years with ASA grade II to III undergoing cardiac catheterization.
Interventions:
Continuous intravenous infusion of a mixture of propofol (4 mg/mL) and ketamine (2 mg/mL) with spontaneous ventilation. The infusion rate was changed and additional boluses of propofol or/and ketamine were given as needed. Hemodynamic, respiratory, and other variables were recorded during the procedure and recovery.
Results:
Mean dose of ketamine was 26 +/- 8.3 microg/kg/min and of propofol, 68.3 +/- 21.7 microg/kg/min. Changes in heart rate and mean arterial pressure of more than 20% from baseline were observed in 4 and 5 patients, respectively. A transient reduction in oxygen saturation because of hypoventilation was observed in 3 patients and responded to oxygen administration and manual assisted ventilation. No other complications were observed.
Conclusions:
The propofol-ketamine mixture is a safe, practical alternative for general anesthesia in pediatric patients undergoing cardiac catheterization.
