AbstractObjective: Sodium bicarbonate is a frequently used electrolyte for the acute treatment of metabolic acidosis in critically ill patients. We performed a systematic review and meta-analysis to determine the effect of sodium bicarbonate on hemodynamics, gas exchange and oximetry in critically children.Methods: A systematic review of published manuscripts was conducted to identify studies of children who received sodium bicarbonate as part of the treatment for metabolic acidosis. A meta-analysis was then conducted to determine the impact of sodium bicarbonate on hemodynamics, gas exchange and oximetry. The following parameters were captured: base deficit, heart rate, mean arterial pressure, blood concentration of carbon dioxide, blood concentration of hydrogen ion, and pulse oximetry.Results: A total of six studies with 341 patients were included in the analyses. All included studies were completed in critically ill infants with a mean age of 1.1 months. The mean dose of sodium bicarbonate was 1.7 meq/kg with a mean time of 67 min prior to repeat hemodynamics being collected after sodium bicarbonate administration. Base deficit significantly improved with a decrease of 2.80 (p = .001) and the partial pressure of carbon dioxide significantly decreased by a mean of -1.65 mmHg (p = .010). There was no change in heart rate, blood pressure, pH, partial pressure of oxygen, or saturation by pulse oximetry.Conclusion: Sodium bicarbonate has a statistically significant but not clinically significant impact on partial pressure of carbon dioxide and base deficit 60 min after sodium bicarbonate administration in critically ill infants. There is no difference noted in pH, partial pressure of oxygen, or saturation by pulse oximetry.
