Neonatal Intensive Care Unit Mixed Lipid Emulsion Use Associated With Reduced Cholestasis at Discharge in Surgical Patients.

INTRODUCTION: Parenteral nutrition associated cholestasis (PNAC) is a common morbidity in neonates requiring total parenteral nutrition (TPN). Previous studies in infants with intestinal failure have shown a benefit of mixed lipid emulsion (MLE) in reducing PNAC. It is not known whether this benefit extends to a general neonatal intensive care unit (NICU) population, where MLE is used on a selective basis. The objective of this study is to examine associations between MLE use and PNAC rate in the general NICU setting. METHODS: This is a retrospective review of NICU patients who received TPN for 7 or more days. We compared patients born between 1/1/2014 and 12/31/2015 (pre-MLE) to patients born between 7/1/2017 and 12/31/2018 (post-MLE). Fisher's exact test and two-sample t-test were used to compare the two groups. RESULTS: There were 353 patients in 2014-2015 and 271 patients in 2017-2018. Demographics were similar between the two groups, but there were more patients with congenital heart disease in the MLE era (P < 0.001). Mortality was similar (6.2% pre-MLE versus 6.3% post-MLE). There was no significant difference in PNAC rate between the pre-MLE (11.5%) and post-MLE (14.1%) patient cohorts (P = 0.342). Among patients receiving MLE (n = 38), 58% developed PNAC, while only 6.4% of the post-MLE cohort not receiving MLE developed PNAC. Of the patients coded with a surgical diagnosis, there was no significant difference in PNAC rates between pre-MLE and post-MLE groups. Discharge rates of PNAC did differ between pre-MLE surgical patients (13.0%) and post-MLE surgical patients (8.2%). In the subgroup of post-MLE surgical patients, PNAC rate differed significantly between those receiving MLE (43.5%) and not receiving MLE (15.4%). However, this difference was resolved by discharge (8.7% versus 7.7%). CONCLUSIONS: There were no significant differences in PNAC rates between the pre-MLE and post-MLE cohorts. However, in surgical patients, MLE was associated with reduced PNAC at discharge, with levels equivalent to those seen in neonates receiving TPN for 7 or more days, despite having a higher starting rate of PNAC. Further studies are needed to determine whether the general NICU population may benefit from MLE or certain selective subpopulations like surgical patients.

Apnea in the term infant.

Whereas apnea of prematurity has been well defined and its pathophysiology extensively studied, apnea in the term infant remains a greater challenge. Unfortunately, clear diagnostic criteria are lacking and pathogenesis and management vary widely. In this review we have arbitrarily organized the discussion chronologically into earlier and later postnatal periods. In the first days of life, presumed apnea may reflect physiologic events such as positional or feeding etiologies, or may be a manifestation of serious pathophysiology, such as a seizure disorder. Beyond the neonatal period, presumed apnea may be characterized as a BRUE event (brief resolved unexplained event; formerly referred to as ALTE: apparent life-threatening event) and most frequently a precipitating event cannot be identified. Medical providers are left with somewhat of a dilemma regarding the need to hospitalize and/or work up such patients.

Medically fragile children: an integrative review of the literature and recommendations for future research.

The literature related to medically fragile children (MFC) is analyzed, and a model is generated to improve quality of care and cost effectiveness. The sources of stress for families include home care professionals, respite care, financial concerns, and limited community resources. Children cared for in hospitals often experience less than desirable quality outcomes. Community-based pediatric extended care facilities may be a means of reducing family stress, improving physiologic and developmental outcomes, and reducing cost. Case management may significantly reduce parental stress and improve the quality of life for these children. Additional systematic study of care options for MFC is essential.
