Hyperkalemia | Relationship Between Potassium Level in Venous Blood Samples Drawn and Heel Sticks In Infants and Newborns

Hyperkalemia research study

What is the primary objective of this study?

The purpose of this study is to find out whether there is a correlation (link) between the level of potassium in blood samples drawn from a vein and those drawn from a heel stick in infants scheduled for elective surgery.

Who is eligible to participate?

Inclusion Criteria: - Infants and babies, ASA physical Status I-III, less than 6 month of age and scheduled to have elective surgery under routine general anesthesia at Children's Memorial Hermann Hospital will be included. Exclusion Criteria: - Babies and infants with documented anemia (< 8 gm), who are bleeding, ASA Classification >III, have sickle cell disease or trait, thalassemia, HIV or DIC will be excluded from the study. Babies with organ failure will be excluded.

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?

Hyperkalemia

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Other:Blood sample drawn from a vein0.5 ml will be drawn from a vein when an IV is started for the surgery or from an IV already in place. The blood will be placed into a heparinized, 1 ml syringe for venous blood gas analysis.

Other:Blood sample drawn from a heel stickA second blood sample, 0.3 ml will be drawn into a capillary pipette from a heel stick for capillary blood gas analysis.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

Blood sample drawn from a vein and from a heel stick0.5 ml will be drawn from a vein when an IV is started for the surgery or from an IV already in place. The blood will be placed into a heparinized, 1 ml syringe for venous blood gas analysis.
