Insights
Sodium bicarbonate administration significantly reduced carbon dioxide levels in children with life-threatening asthma (LTA). This treatment also improved respiratory distress, suggesting potential benefits for LTA management.
Area of Science:
- Pediatric Critical Care Medicine
- Respiratory Medicine
- Emergency Medicine
Background:
- Life-threatening asthma (LTA) presents a significant challenge in pediatric intensive care.
- Refractory status asthmaticus often requires advanced interventions.
- Acidosis is a critical concern in severe asthma exacerbations.
Purpose of the Study:
- To evaluate the impact of sodium bicarbonate on carbon dioxide levels in pediatric patients with LTA.
- To assess the clinical effectiveness of sodium bicarbonate in improving respiratory distress in LTA.
Main Methods:
- Retrospective study conducted in a pediatric intensive care unit (PICU).
- Seventeen children with LTA who received intravenous sodium bicarbonate were analyzed.
- Sodium bicarbonate was administered to acidotic patients (pH < 7.15) with refractory status asthmaticus.
Main Results:
- A statistically significant decrease in partial pressure of carbon dioxide (Pco2) was observed post-sodium bicarbonate infusion (p = 0.007).
- Clinical improvement in respiratory distress was noted in the majority of patients.
- Five patients required intubation and mechanical ventilation, with some receiving bicarbonate post-intubation.
Conclusions:
- Intravenous sodium bicarbonate administration was associated with a significant reduction in Pco2 in children with LTA.
- The treatment correlated with an improvement in respiratory distress.
- Further controlled, prospective studies are warranted to confirm the benefits of sodium bicarbonate in LTA.
Objectives:
To assess the effect of administration of sodium bicarbonate on carbon dioxide levels in children with life-threatening asthma (LTA) and to evaluate the clinical effect of this treatment.
Study Design:
Retrospective study.
Setting:
A pediatric ICU (PICU) of a tertiary care university hospital.
Patients:
Seventeen children with LTA who received sodium bicarbonate.
Measurements And Results:
In January 1999, a new protocol for the treatment of LTA was initiated in our institution, incorporating the use of IV sodium bicarbonate in acidotic patients (pH < 7.15) with refractory status asthmaticus. Since January 1999, sodium bicarbonate was administered to 17 patients; 5 patients received two or three doses of sodium bicarbonate. In three patients, sodium bicarbonate was administered after intubation. Intubation and mechanical ventilation were performed in five patients before admission to the PICU, and in one patient during admission. There was a significant decrease of Pco(2) after sodium bicarbonate infusion (p = 0.007). An improvement of respiratory distress in all but one patient was seen as well.
Conclusions:
Administration of sodium bicarbonate in 17 children with LTA was associated with a significant decrease in Pco(2) and an improvement of respiratory distress. The possible benefits of sodium bicarbonate in LTA deserve further study in a controlled, prospective design.

Diagnosing Acidosis and Alkalosis
First, the pH level is assessed to determine whether the blood pH is normal (7.35–7.45), low (acidosis), or high (alkalosis).

Respiratory Acidosis and Alkalosis
Respiratory acidosis occurs due to an increase in the partial pressure of carbon dioxide PCO2 in the blood. It often arises from shallow breathing or impaired gas exchange caused by...
