The use of piperacillin/tazobactam (in association with amikacin) in neonatal sepsis: efficacy and safety data.

Piperacillin/tazobactam (P/T) has been used in NICU since 1999 as part of the empirical treatment for presumed sepsis. We studied the microbiological and clinical efficacy and safety of P/T use in newborns with sepsis, using a retrospective analysis of medical records of all newborns treated with P/T (in association with amikacin) during 1999-2003. P/T plus amikacin was used for 353 episodes of presumed sepsis occurring in 252 newborns: 105 episodes occurred in 100 newborns treated for 5-14 d while in 248 (70%) episodes the treatment was discontinued after 2-3 d. 123 pathogens were isolated from the blood cultures (40 in the 5-14 d group and 83 in those treated for 2-3 d only). There were 56 Gram-negative, 55 Gram-positive and 12 Candida spp. isolates. Klebsiella spp. (40%) and E. coli (30%) were the most commonly isolated Gram-negative pathogens; coagulase-negative Staphylococcus (CONS) represented 95% of the Gram-positive pathogens isolated. Pathogen eradication was achieved within 48-72 h of therapy in 93% Gram-negative organisms. There were no clinical, laboratory or cranial ultrasound adverse effects associated with P/T use. We conclude that P/T in association with amikacin is microbiologically and clinically efficacious and safe in the treatment of sepsis in newborns.

The fear of necrotizing enterocolitis versus achieving optimal growth in preterm infants--an opinion.

UNLABELLED: Very-low-birthweight (VLBW) infants suffer marked growth delay despite well-intentioned efforts at combining enteral and parenteral nutrition. Fear of necrotizing enterocolitis (NEC) has traditionally influenced neonatologists toward delaying and progressing slowly with enteral feeding, while supporting the infant with parenteral nutrition. Current evidence suggests significant benefits of enteral feeding that is started early and advanced at rates of 20-35 ml/kg/d. CONCLUSION: We conclude that fear of inadequate growth should replace the fear of NEC in guiding nutritional strategies for these infants.

Early weight gain does not decrease the incidence of low birth weight and small for gestational age triplets in mothers with normal pre-gestational body mass index.

OBJECTIVE: To examine if the recommended weight gain of >680 g/week during the first 24 weeks of pregnancy decreases the frequency of adverse birth weight outcomes in triplet mothers with a normal pregravid BMI. STUDY DESIGN: Retrospective observational study of a large sample of triplet mothers with a normal (19.8-26) pregravid BMI. Adequate, average, and inadequate weight gains were defined as >680, 500-680, and <500 g/week. Outcome measures were the incidence of >or=1 SGA infant and total triplet birth weight <4500 g. RESULTS: Of the 1166 triplet mothers, 208 (17.8%) gained >680 g/week during their pregnancy. This presumed adequate weight gain did not reduce the incidence of SGA triplets or that of total birth weight <4500 g, irrespective of parity. These adverse birth weight outcomes were 2 to 3.5 times lower among multiparous compared to nulliparous mothers. CONCLUSION: Early weight gain of >680 g/week in triplet mothers with a normal pre-pregnancy BMI is not associated with a decrease in the incidence of adverse outcomes. Weight gain recommendations in triplet pregnancies should be realistic and associated with a low risk-benefit ratio.

Early adequate maternal weight gain is associated with fewer small for gestational age triplets.

OBJECTIVE: To examine whether the recommended weight gain during the first 24 weeks reduces the frequency of SGA triplets. STUDY DESIGN: We used data collected by the Women's Health Division of Matria Healthcare, Inc (Marietta, GA). We studied the frequency of SGA triplets (birth weight <10th percentile by triplet standards) by weight gain, parity, and pregravid BMI category. Adequate weight gain was defined as >16.2 kg at 24 weeks and BMI categories were defined as underweight (<19.8), normal (19.8-26), and obese (BMI>26). RESULTS: We studied 2890 triplet sets. Adequate weight gain reduces the frequency of SGA triplets, irrespective of pregravid BMI category and parity, except for obese nulliparous women. However, the reduced frequency of SGA infants was significant only in underweight nulli-paras (OR 0.3, 95% CI 0.1, 0.9). CONCLUSION: Higher pregravid BMI and parity seem to reduce the occurrence of SGA triplets. However, lean mothers, especially nulliparas, may be the most important target population for nutritional intervention in triplet pregnancies.
