Fractures in premature infants.

Fractures not related to birth trauma were diagnosed in 1.2% of preterm infants between the 24th and the 160th day of life. The clinical and radiologic findings as well as the follow-up on 12 preterm infants with one or more fractures were reviewed. Fractures occurred either in the ribs or long bones or both. Their clinical history, the radiographic appearance, and laboratory data suggest that most of the infants may have suffered from bone loss associated with low intake of calcium and phosphorus. Improving the metabolic status and removing the risk factors prevented further fractures and led to good healing.

Plasma ammonia levels in preterm infants receiving parenteral nutrition with crystalline L-amino acids.

In order to investigate the severity and incidence of hyperammonemia in preterm infants receiving total parenteral nutrition (TPN) with crystalline L-amino acids having high arginine content (Travasol), we determined the plasma ammonia (PA) levels in a group of 29 preterm infants on TPN, weekly and 1 wk posttherapy. Their mean gestational age was 29.9 +/- 2.6 wk and mean birth weight 1208 +/- 262 g. Thirty five blood samples obtained from 15 preterm infants not on TPN with mean gestational age 32.2 +/- 1.9 wk and a birth weight of 1495 +/- 161 g served as a control. In the parenteral nutrition group the mean PA level (140 +/- 58 micrograms/100 ml) was significantly higher (p less than 0.001) than that in the same group one week post TPN (97 +/- 34 micrograms/100 ml) and in the control group (86 +/- 35 micrograms/100 ml). The incidence of hyperammonemia (greater than 160 micrograms/100 ml) was 30% in the TPN group versus 3% in the controls (p less than 0.01). Maximal PA level during that treatment was 405 versus 216 micrograms/100 ml 1 wk post-TPN versus 163 micrograms/100 ml in the controls. The data show a significant increase in PA levels in preterm infants receiving TPN with Travasol, possibly because of its high glycine content.
