Immunization status of 2-year-olds in a prepaid health care system.

The immunization compliance among 2-year-olds in a prepaid healthcare system in Indianapolis was studied. Since appointments and immunizations are covered benefits, immunization rates should approach 100%; complete immunizations were found in only 72%. Problems identified included transient membership, failure to determine immunization status on patients, reluctance to administer immunizations to children with mild illnesses, asking patients to return for administration of immunizations without a physician exam and record-keeping errors.

Breastfeeding the premature newborn: a protocol without bottles.

Premature babies can, and should, breastfeed. Although establishing a milk supply and the transition to breastfeeds can be difficult, both are possible. Because early bottle-feeds can impede later attempts to breastfeed, the newborn intensive care unit at Methodist Hospital in Indianapolis developed a protocol for successfully breastfeeding premature infants that excludes bottle-feeding. The babies are introduced to the breast as soon as possible, and supplementation is provided by gavage feeding. The amount of supplement is adjusted based on maternal and nursing observations of the breastfeeding experience. The hospital stays are not prolonged by this approach and most of the babies whose mothers intended to breasfeed are discharged exclusively breastfeeding.

Risk factors for late-onset necrotizing enterocolitis.

The etiology of necrotizing enterocolitis (NEC) is unknown. We conducted a retrospective, case-controlled study of 23 infants hospitalized during a five-year period who developed NEC after the 11th day of life (late-onset NEC). We evaluated 58 different factors among the case and control populations to determine if there were any statistically significant differences between the two populations. Our data showed a statistically significant association between the occurrence of NEC and the use of ventilatory support (both mechanical ventilation and nasopharyngeal continuous positive airway pressure (NPCPAP)), the transpyloric (TP) feeding route and the addition of glucose polymers to feeds.

Validity of arterial hematocrits in newborns.

Various methods are used to obtain specimens for hematocrit determination in neonates. We evaluated arterial sampling and found this method to be acceptable. Arterial values correlated closely with simultaneously obtained venous samples. Venous blood obtained with a tourniquet had a significantly higher hematocrit than that obtained without a tourniquet.

Subdural collection of intravenous fat emulsion in a neonate. Complication of central venous catheterization for total parenteral nutrition.

An infected subdural collection of intravenous fat emulsion (Intralipid) was diagnosed in a 5-week-old premature infant who was receiving total parental nutrition (TPN) through a facial vein cutdown. This fluid was successfully drained and the infection, due to Staphylococcus epidermidis, was treated with vancomycin. We postulate that the subdural collection occurred as a result of septic thrombosis of the internal jugular vein with subsequent retrograde flow and infiltration of Intralipid from the bridging veins into the subdural space. This complication of central TPN has not been reported previously.
