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. 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. 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. 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. [ABSTRACT FROM AUTHOR]

The objectives of this study were to characterize the use of sodium bicarbonate in pediatric cardiac admissions that experience cardiac arrest, to determine sodium bicarbonate use over the years, and to determine the impact of sodium bicarbonate on length of admissions, billed charges, and inpatient mortality. A cross-sectional study was conducted utilizing the Pediatric Health Information System database. Characteristics of admissions with and without sodium bicarbonate were initially compared by univariate analyses. The frequency by which sodium bicarbonate was used was compared by year. Regression analyses were conducted to determine the impact of sodium bicarbonate on length of stay, billed charges, and inpatient mortality. A total of 3987 (50.3%) of pediatric cardiac intensive care admissions with cardiac arrest utilized sodium bicarbonate; however, frequency changed from 62.1% in 2004 to 43.7% in 2015. Linear regression analysis demonstrated a decrease in length of stay (27.5 days, p < 0.01) and billed charges ($470,906, p < 0.01). Logistic regression analysis demonstrated an increase in mortality (odds ratio 1.77, 95% confidence interval 1.56-2.01). In conclusion, sodium bicarbonate is being used with less frequency over the last years in pediatric cardiac admissions with cardiac arrest. After adjustment for cardiac diagnoses, comorbidities, vasoactive medications, and other resuscitation medications, sodium bicarbonate is independently associated with increased mortality.
