Why the study?

Does sodium bicarbonate compared to sodium carbonate improve pH without exacerbating hypercarbia in mixed venous blood during steady-state and low-perfusion conditions in dogs?

Population

15 adult mongrel dogs of both sexes subjected to hemorrhagic shock

Comparison

Sodium bicarbonate 1 mEq/kg infused over 5 min… vs Sodium carbonate 1 mEq/kg infused over 5 min…

Design

Preclinical

Follow-up

15 minutes after buffer infusion

Key result

Sodium bicarbonate infusion had no deleterious effect on the pH or Pco2 of mixed, portal, or hepatic venous blood in steady and low perfusion states compared to sodium carbonate.

Overview

Supports bicarbonate safety vs carbonate in canine low-perfusion states without hypercarbia; leaves open human translation and lactate effects.

Structured PICO

Does sodium bicarbonate compared to sodium carbonate improve pH without exacerbating hypercarbia in mixed venous blood during steady-state and low-perfusion conditions in dogs?

P
Population
15 adult mongrel dogs subjected to steady-state and hemorrhagic shock conditions to compare the effects of sodium bicarbonate and sodium carbonate.
I
Intervention
Sodium bicarbonate 1 mEq/kg (1M solution) infused over 5 min before and after induction of shock (n=8)
C
Comparator
Sodium carbonate 1 mEq/kg (0.5M solution) infused over 5 min before and after induction of shock (n=7)
O
Outcome
Changes in carbon dioxide tension (PCO2) and pH of mixed, portal, and hepatic venous blood and arterial bloodsurrogate

Main Result

p-value: p=<0.05

Sodium bicarbonate can be safely used in disturbed circulatory states without causing deleterious venous hypercarbia, and it increases hepatic lactate uptake compared to sodium carbonate.

Limitations

  • Animal model
  • Small sample size
  • Short observation period

Cite This Study

Kon et al. (1995) studied Hemorrhagic shock (n=15). Sodium bicarbonate vs. Sodium carbonate was evaluated on pH in mixed venous blood at 1 minute after buffer infusion (p=<0.05). Sodium bicarbonate infusion had no deleterious effect on the pH or Pco2 of mixed, portal, or hepatic venous blood in steady and low perfusion states compared to sodium carbonate.
