course by systems: respiratory: because of his mild respiratory distress, the patient was placed on nasopharyngeal cpap. he was able to be transitioned to room air by day of life #2. the patient remained in room air since that time. the patient had several apneic spells initially and was started on caffeine. he remained on 5 mg per kg per day. he continued to have one to two spells daily. the patient was discontinued on caffeine on in anticipation of discharge within a week ago or two. the patient continued to have very mild as and bs, approximately one to two per day, usually associated

patient was initially started on intravenous fluids and then transitioned to full feeds over the next several days. the patient reached full feeds on and advanced on calories to a maximum of enfamil preemie formula 26 kcal per ounce with promod and showed adequate weight gain. the patient was then weaned to the current formula of enfamil 20 and continues to show weight gain on his regimen of

substances other phototherapy diagnoses: single liveborn, born in hospital, delivered by cesarean section observation for suspected infectious condition neonatal jaundice associated with preterm
