Neonatal Intensive Care Unit Resource Use for Infants at 22 Weeks' Gestation in the US, 2008-2021.

Importance: During the past decade, clinical guidance about the provision of intensive care for infants born at 22 weeks' gestation has changed. The impact of these changes on neonatal intensive care unit (NICU) resource utilization is unknown. Objective: To characterize recent trends in NICU resource utilization for infants born at 22 weeks' gestation compared with other extremely preterm infants (≤28 weeks' gestation) and other NICU-admitted infants. Design, Setting, and Participants: This is a serial cross-sectional study of 137 continuously participating NICUs in 29 US states from January 1, 2008, through December 31, 2021. Participants included infants admitted to the NICU. Data analysis was performed from October 2022 to August 2023. Exposures: Year and gestational age at birth. Main Outcomes and Measures: Measures of resource utilization included NICU admissions, NICU bed-days, and ventilator-days. Results: Of 825 112 infants admitted from 2008 to 2021, 60 944 were extremely preterm and 872 (466 [53.4%] male; 18 [2.1%] Asian; 318 [36.5%] Black non-Hispanic; 218 [25.0%] Hispanic; 232 [26.6%] White non-Hispanic; 86 [9.8%] other or unknown) were born at 22 weeks' gestation. NICU admissions at 22 weeks' gestation increased by 388%, from 5.7 per 1000 extremely preterm admissions in 2008 to 2009 to 27.8 per 1000 extremely preterm admissions in 2020 to 2021. The number of NICU admissions remained stable before the publication of updated clinical guidance in 2014 to 2016 and substantially increased thereafter. During the study period, bed-days for infants born at 22 weeks increased by 732%, from 2.5 per 1000 to 20.8 per 1000 extremely preterm NICU bed-days; ventilator-days increased by 946%, from 5.0 per 1000 to 52.3 per 1000 extremely preterm ventilator-days. The proportion of NICUs admitting infants born at 22 weeks increased from 22.6% to 45.3%. Increases in NICU resource utilization during the period were also observed for infants born at less than 22 and at 23 weeks but not for other gestational ages. In 2020 to 2021, infants born at less than or equal to 23 weeks' gestation comprised 1 in 117 NICU admissions, 1 in 34 of all NICU bed-days, and 1 in 6 of all ventilator-days. Conclusions and Relevance: In this serial cross-sectional study of 137 US NICUs from 2008 to 2021, an increasing share of resources in US NICUs was allocated to infants born at 22 weeks' gestation, corresponding with changes in national clinical guidance.

Trends in Procedural Closure of the Patent Ductus Arteriosus among Infants Born at 22 to 30 Weeks' Gestation.

OBJECTIVE: To describe recent trend in procedural closure of the patent ductus arteriosus (PDA) among premature infants and compare the clinical characteristics of infants receiving surgical vs transcatheter closure. STUDY DESIGN: We conducted a descriptive, retrospective cohort study of preterm infants born between 220/7 and 296/7 weeks' gestation from 2014 through 2021. Infants were identified from the Pediatrix Clinical Data Warehouse. We excluded infants with any major congenital anomaly. We identified all preterm infants with a PDA and all those who underwent procedural closure (surgical ligation or transcatheter occlusion) and compared changes over time using ANOVA for continuous variables and the Cochran-Armitage trend test to evaluate time-related changes in proportions. RESULTS: The study cohort included 64 580 infants, of whom 24 028 (37.2%) were diagnosed with a PDA. The number of infants receiving any procedural closure of the PDA decreased from 371 (4.4%) in 2014 to 144 (1.9%) in 2021. During the same period, number of surgical ligations decreased from 369 (4.36%) to 64 (0.84%), and the number of transcatheter occlusions increased from 2 (0.02%) to 80 (1.05% p for all < 0.001). The median age at time of surgical ligation increased from 25 days (10th and 90th percentile, 10, 61) to 31 days (10th and 90th percentile, 16, 66), and the median age of transcatheter occlusion decreased from 103 days (10th and 90th percentile, 32, 150) to 43 days (10th and 90th percentile, 22, 91). CONCLUSIONS: There was a decrease in surgical closure and an increase in transcatheter occlusion of the PDA in infants born at 22-30 weeks' gestation from 2014 to 2021. Despite the decline in overall procedural closure, the rate of transcatheter occlusion surpassed surgical ligation by 2021. Narrowing differences in the median age and weight at closure suggest increasing overlap in the types of infants who received each type of procedural closure.

Initial resuscitation of a neonate with congenital maxillomandibular syngnathia: A case report and literature review.

We report a full-term male neonate found to have undiagnosed syngnathia requiring extensive resuscitation at birth followed by urgent tracheostomy. We conducted a systematic literature review to study the presentation, resuscitation methods, and outcomes of neonates with congenital syngnathia. Of the 174 cases reported to date, 91 had initial resuscitation data available. Extensive resuscitation was required in 16 of these 91 infants (18%). This ranged from nasal intubation to emergent tracheostomy. These neonates are potentially higher risk deliveries for which methods in addition to those recommended by the American Heart Association neonatal resuscitation guidelines may be needed.

Intensive care resources required to care for critically ill children with focal intracranial infections.

The authors reviewed cases in which children with a focal infection inside the head (ex: a brain abscess) were cared for in their pediatric ICU to describe the frequency of complications and quantify the ICU resources needed (ex: breathing tube, blood pressure medications, and/or an intracranial pressure monitor). This information helps clarify illness severity and has identified complications that we should further investigate to improve care for these children.
