AIMThe main objective of this study was to evaluate the association between prematurity and the time to achieve full enteral feeding in newborns with gastroschisis. The second objective was to analyze the associations between length of hospital stay and time to achieve full enteral feeding with mode of delivery, birth weight and surgical procedure.METHODSThe medical records of newborns with gastroschisis treated between 1997 and 2007 were reviewed. Two groups were considered: those delivered before 37 weeks (group A) and those delivered after 37 weeks (group B). The variables of gestational age, mode of delivery, birth weight, time to achieve full enteral feeding, length of hospital stay and surgical approach were analyzed and compared between groups.RESULTSForty-one patients were studied. In Group A, there were 14 patients with a mean birth weight (BW) of 2300 g (range=1680–3000) and a mean gestational age (GA) of 36 weeks (range=34–36). In group B, there were 24 patients with a mean BW of 2700 g (range=1500–3550) and a mean GA of 38 weeks (range=37–39). The mean time to achieve full enteral feeding was 30.1±6.7 days in group A and 17.0±2.5 days in group B (p=0.09) with an OR of 0.82 and a 95% CI of 0.20–3.23 after adjustment for sepsis and BW. No statistical difference was found between low BW (<2500 g), mode of delivery and number of days to achieve full enteral feeding (p=0.34 and p=0.13, respectively). Patients with BW over 2500 g had fewer days in the hospital (22.9±3.1 vs. 35.7±5.7 days; p=0.06).CONCLUSIONThe results of this study do not support the idea of anticipating the delivery of fetuses with gastroschisis in order to achieve full enteral feeding earlier.

Results:We analyzed 1011 prescriptions of 84 active substances, made in 218 admissions. In 42.9% of the cases, medicines were used according to Summary of Product Characteristics information; 27.9% of drugs were approved for neonatal period but used in an off-label manner; off-label drugs for neonates were used in 10.1%, whereas those with undetermined approval state and contraindicated were used 6.0% and 8.7% of the cases, respectively. Unlicensed prescriptions accounted for 4.4% of total. Preterm received a higher rate of drugs used according to Summary of Product Characteristics (p < 0.0001), whereas full-term received more off-label drugs for dose/frequency (p < 0.0001) and contra-indicated for neonates (p < 0.012). Discussion: Preterm neonates received a higher median number of drugs, since they stayed longer in the unit. The main reason for off-label prescribing was the use of doses/frequencies of administration different from those stated in the Summary of Product Characteristics, suggesting that updating these documents is necessary. Manipulation of medicines is one of the causes for unlicensed drugs use, emphasizing the lack of appropriate formulations for neonatal age. Conclusion:Progresses have been made to reduce the risks of off-label/unlicensed prescriptions, but competent authorities must continue their efforts to develop safer and more effective drugs for neonatal period.

Invasive ventilation is often necessary for the treatment of newborn infants with respiratory insufficiency. The neonatal patient has unique physiological characteristics such as small airway caliber, few collateral airways, compliant chest wall, poor airway stability, and low functional residual capacity. Pathologies affecting the newborn's lung are also different from many others observed later in life. Several different ventilation modes and strategies are available to optimize mechanical ventilation and to prevent ventilator-induced lung injury. Important aspects to be considered in ventilating neonates include the use of correct sized endotracheal tube to minimize airway resistance and work of breathing, positioning of the patient, the nursing care, respiratory kinesiotherapy, sedation and analgesia, and infection prevention, namely, the ventilator-associated pneumonia and nosocomial infection, as well as prevention and treatment of complications such as air leaks and pulmonary hemorrhage. Aspects of ventilation in patients under ECMO (extracorporeal membrane oxygenation) and in palliative care are of increasing interest nowadays. Online pulmonary mechanics and function testing as well as capnography are becoming more commonly used. Echocardiography is now a routine in most neonatal units. Near infrared spectroscopy (NIRS) is an attractive tool potentially helping in preventing intraventricular hemorrhage and periventricular leukomalacia. Lung ultrasound is an emerging tool of diagnosis and can be of added value in helping monitoring the ventilated neonate. The aim of this scientific literature review is to address relevant aspects concerning the respiratory care and monitoring of the invasively ventilated newborn in order to help physicians to optimize the efficacy of care.
