[Hemodynamic effects of intravenous omeprazole in critically ill children]

Area of Science:

• Pediatric Critical Care Medicine
• Pharmacology
• Cardiovascular Physiology

Background:

• Critically ill children often experience hemodynamic instability.
• Omeprazole is used for gastrointestinal bleeding prophylaxis but its cardiovascular effects are unknown.
• This study investigates the hemodynamic impact of intravenous omeprazole in pediatric patients.

Purpose of the Study:

• To assess hemodynamic changes following intravenous omeprazole administration in critically ill children.
• To compare the effects of two different intravenous omeprazole doses (0.5mg/kg vs. 1mg/kg).

Main Methods:

• A randomized prospective study involved 37 critically ill children (1 month to 14 years).
• Participants received either 0.5mg/kg or 1mg/kg intravenous omeprazole over 20 minutes.
• Hemodynamic parameters (heart rate, blood pressure, central venous pressure) and ECG were monitored before and after infusion.

Main Results:

• No significant changes were observed in heart rate, blood pressure, or central venous pressure.
• Electrocardiogram findings remained stable throughout the study period.
• No dose-dependent differences or need for inotropic support modification were noted between the two omeprazole groups.

Conclusions:

• Intravenous omeprazole at both 0.5mg/kg and 1mg/kg is hemodynamically safe in critically ill children.
• The drug can be safely administered for gastrointestinal bleeding prophylaxis without adverse cardiovascular effects.
• Findings support the use of intravenous omeprazole in pediatric intensive care settings.
