Insights
Ketamine-propofol sedation offers greater hemodynamic stability in pediatric atrial septal defect closures compared to dexmedetomidine-propofol. Both sedation methods resulted in similar recovery times for children undergoing the procedure.
Area of Science:
- Pediatric Cardiology
- Anesthesiology
- Pharmacology
Background:
- Transcatheter closure of atrial septal defects (ASDs) is a common pediatric cardiac procedure.
- Sedation is crucial for patient comfort and procedural success during ASD closure.
- Different anesthetic agents may have varying effects on hemodynamic stability and recovery.
Purpose of the Study:
- To compare the efficacy of dexmedetomidine-propofol versus ketamine-propofol sedation.
- To evaluate hemodynamic stability, immobility, and recovery time in pediatric patients undergoing transcatheter ASD closure.
- To determine the optimal sedation strategy for this specific pediatric cardiac intervention.
Main Methods:
- A study involving 46 pediatric patients scheduled for transcatheter ASD closure.
- Two groups were formed: dexmedetomidine-propofol (n=23) and ketamine-propofol (n=23).
- Specific induction and maintenance dosages for each anesthetic combination were administered.
Main Results:
- The dexmedetomidine-propofol group showed significantly more instances of decreased mean arterial pressure (47.8%) and heart rate (43.4%) compared to the ketamine-propofol group (4.3% and 13%, respectively).
- Lower heart rates were consistently observed in the dexmedetomidine group after the initial 10 minutes.
- Recovery times were comparable between the two groups (15.86 ± 6.50 min vs. 19.65 ± 8.19 min).
Conclusions:
- Ketamine-propofol sedation is associated with less hemodynamic instability in pediatric ASD closure compared to dexmedetomidine-propofol.
- The ketamine-propofol combination provided adequate conditions for the transcatheter intervention.
- No significant difference in recovery times was noted between the two sedation regimens.
Aim:
This study aimed to compare the effects of dexmedetomidine-propofol and ketamine-propofol sedation on haemodynamic stability, immobility, and recovery time in children who underwent transcatheter closure of atrial septal defects.
Methods:
In all, 46 children scheduled for transcatheter closure of atrial septal defects (n = 46) were included. The dexmedetomidine-propofol group (n = 23) received dexmedetomidine (1 μg/kg) and propofol (1 mg/kg) for induction, followed by dexmedetomidine (0.5 μg/kg/hour) and propofol (100 μg/kg/minute) for maintenance. The ketamine-propofol group (n = 23) received ketamine (1 mg/kg) and propofol (1 mg/kg) for induction, followed by ketamine (1 mg/kg) and propofol (100 μg/kg/minute) for maintenance.
Results:
In all, 11 patients in the dexmedetomidine group (47.8%) and one patient (4.3%) in the ketamine group demonstrated a decrease ≥20% from the baseline in mean arterial pressure (p = 0.01). Heart rates decreased ≥20% from the baseline value in 10 patients (43.4%) in the dexmedetomidine group and three patients (13%) in the ketamine group (p = 0.047). Heart rate values were observed to be lower in the dexmedetomidine group throughout the procedure after the first 10 minutes. The number of patients requiring additional propofol was higher in the dexmedetomidine group (p = 0.01). The recovery times were similar in the two groups--15.86 ± 6.50 minutes in the dexmedetomidine group and 19.65 ± 8.19 minutes in the ketamine group; p = 0.09.
Conclusion:
The ketamine-propofol combination was less likely to induce haemodynamic instability, with no significant change in recovery times, compared with the dexmedetomidine-propofol combination. The ketamine-propofol combination provided good conditions for the intervention.

Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
