Clinical Question

Should Sodium Bicarbonate be used to treat Diabetic Ketoacidosis ?

Background

Sodium bicarbonate is a solution which help alkalanizing the blood by binding the H+ and converting it to water and Co2. Many Physicians use it to treat DKA, but based on what ? Is there any evidence supporting its use ?

Pro Argument

Looking for any studies supporting its use ...

Con Argument

Trial 1

21 patients underwent RCT

  • 10 patients (PH 6.9-7.14) received NaHco3
  • 11 patients in the control group

Results: No differences in Glucose level, bicarb level nor PH [1]

Trial 2

Prospective, Randomized, Blinded and cross over study included 14 patients

  • HCO3 level <17
  • Received Sodium Bicarbonate 2mmol/kg over 15 minutes

Results: Sodium Bicarbonate decreased Ionized Calcium, increased Paco2 and didn't improve hemodynamics[2]

Trial 3

Review Article included patients with PH<7

  • Results: Sodium Bicarbonate didn't decrease time to improvement nor to hospital discharge[3]

Trial 4

Retrospective Study of 39 patients with PH<7.1

  • 24 patients received sodium bicarbonate
  • 15 patients control
  • Results: More Hypokalemia in the experiment group, No differences in clinical or biochemical parameters [4]

Trial 5

Retrospective of 147 pediatric DKA cases with PH<7.15

  • 90 patients received bicarbonate
  • 57 patients contol

Results:Bicarbonate didn't improve clinical outcomes, but hospitalization was prolonged with the bicarb group [5]

Trial 6

Systematic Review of 44 studies Results: Bicarbonate use increased cerebral edema and prolonged hospitalization in pediatrics age group and increased ketosis and need for potassium supplementation[6]
