The study design described previously lends itself to a brief investigation into an important clinical phenomenon during fluid resuscitation that will be investigated as a secondary outcome to this study. One consideration for the use of the Lactated Ringer's solution clinically is the incidence of hyperchloremic metabolic acidosis with the use of normal saline during fluid resuscitation.[8] Using our point-of-care meter (the iSTAT 1 analyzer) we will measure not only serum lactate but also a complete metabolic panel prior to and subsequent to the delivery of the 30 ml/kg fluid administration. We will subsequently analyze changes in serum sodium, chloride, potassium, and bicarbonate in each of the treatment groups, assessing for the degree of derangement that occurs in those electrolytes, and specifically evaluating for any trend toward hyperchloremic metabolic acidosis in the normal saline group.
