Randomized Controlled Trial Comparative Study Clinical TrialComparison of reflection and transmission pulse oximetry after open-heart surgery.
To determine if there was a difference between reflection and transmission pulse oximeters in their ability to regain data display after hypothermia in patients recovering from open-heart surgery. ⋯ The forehead reflection probe regained signal detection earlier than the transmission probe on the ear lobe in patients with compromised peripheral blood flow and cool periphery. This finding may be due to higher skin temperature at the reflection probe site, since the systemic hemodynamic conditions were equal at the time of the data acquisition of both sensors.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of continuous versus intermittent furosemide administration in postoperative pediatric cardiac patients.
To compare the effects of furosemide administered by intermittent iv infusion vs. continuous iv infusion on urine output, hemodynamic variables, and serum electrolyte concentrations. ⋯ Furosemide administered by continuous iv infusion is advantageous in the post-operative pediatric patient because of a more controlled and predictable urine output with less drug requirement and less urinary loss in sodium and chloride.
