infectious disease: due to his prematurity, was evaluated for sepsis upon admission to the neonatal intensive care unit. a complete blood count was within normal limits. a blood culture grew gram-positive cocci identified as streptococcus viridans. he was recultured on day of life 1 and started on ampicillin and gentamicin. the 2nd culture prior to starting antibiotics was no growth, but it was decided to administer a 7-day course of ampicillin. the course was completed on . a lumbar puncture was performed on , , with results 1 red blood cell, 1 white blood cell per high power field. differential was 1% polys, 67% lymphocytes, 31% monocytes, protein of 79, glucose of 54, and negative gram stain. culture was negative. initial strep viridans culture was penicillin-sensitive. 5. hematological: hematocrit at birth was 54.7%. did not receive any transfusions of blood products. he was begun on iron supplementation, and is receiving ferinsol 0.3 ml daily (4 mg/kg/day). 6. gastrointestinal: required treatment for unconjugated hyperbilirubinemia with phototherapy. peak serum bilirubin occurred on day of life 2, total of 8.8 mg per deciliter. he received 2 days of phototherapy. 7. neurology: has maintained a normal neurological exam, and there are no neurological concerns at the time of discharge. 8. sensory: audiology: hearing screening is recommended prior to discharge. condition at discharge: good. physical exam at discharge: general: nondysmorphic preterm infant in no acute distress. skin: warm and dry. color pink. head, eyes, ears, nose, throat:

hospital for continuing level ii care. the primary pediatrician is dr. , , , , phone number (. care and recommendations at the time of discharge: 1. feeding: 150 ml per kilogram per day of breast milk or similac special care 24 calorie per ounce formula. 2. ferinsol 0.3 ml po daily (4 mg/kg/day). 3. iron supplementation is recommended for preterm and low birth weight infants until 12 months of corrected age. all infants fed predominantly breast milk should receive vitamin d supplementation at 200 international units daily. this may be provided as multivitamin preparation and continued until

date. 6. no immunizations have been administered. discharge diagnoses: 1. prematurity 33-1/7-weeks gestation. 2. twin #2 of a twin gestation. 3. streptococcus viridans bacteremia. 4. unconjugated hyperbilirubinemia. , md procedure: spinal tap incision of lung parenteral infusion of concentrated nutritional substances enteral infusion of concentrated nutritional substances other phototherapy diagnoses: twin birth, mate liveborn, born in hospital, delivered by cesarean section neonatal jaundice associated with preterm delivery primary apnea of newborn neonatal bradycardia other preterm
