Trisomy 18 is the second most common aneuploidy syndromes in live born infants. It is associated with high mortality rates, estimated to be 75%–95% in the first year of life, as well as significant morbidity in survivors. The low survival is largely due to the high prevalence of severe congenital anomalies in infants with this diagnosis. However, interventions to repair or palliate those life‐threatening anomalies are being performed at a higher rate for these infants, resulting in increased rates of survival beyond the first year of life. While it is well documented that trisomy 18 is associated with several cardiac malformations, these patients also have respiratory, neurological, neoplastic, genitourinary, abdominal, otolaryngologic, and orthopedic complications that can impact their quality of life. The goal of this review is to present a comprehensive description of complications in children with trisomy 18 to aid in the development of monitoring and treatment guidelines for the increasing number of providers who will be caring for these patients throughout their lives. Where the evidence is available, this review presents screening recommendations to allow for more rapid detection and documentation of these complications.

Trisomy 13 is one of the three most common aneuploidy syndromes in live‐born infants. It is associated with mortality rates as high as 90% within the first year of life, in large part, due to the high prevalence of severe congenital abnormalities that increase mortality and morbidity. However, life‐saving and life‐prolonging medical interventions are being performed at a higher rate for these infants, resulting in increased rates of survival. Although cardiac complications have been well described in infants with trisomy 13, these patients also experience other complications such as respiratory, neurological, genitourinary, abdominal, otolaryngologic, and orthopedic complications that can impact their quality of life. The goal of this review is to present a comprehensive description of complications in children with trisomy 13 to aid in the development of monitoring and treatment guidelines for the increasing number of providers who will be caring for these patients throughout their lives. Where the evidence is available, this review presents screening recommendations to allow for more rapid detection and documentation of these complications.

This study aimed to examine the impact of timing of extubation on feeding outcomes in neonates after surgery for congenital heart disease. This was a single-center retrospective study between December 2014 and June 2020. Patients were divided into three categories: extubated in the OR (immediate), extubated in the intensive care unit (ICU) between 0 and 3 days post-procedure (early), and extubated >3 days post-procedure (delayed). Comparing the immediate and early groups, we found no difference in time to first enteral feed (1.3 days (1.0–3.4) vs. 2.3 days (1.1–3.3), p = 0.27). There was no difference in time to first oral feed (2.0 days (1.1–4.5) vs. 3.1 days (1.8–4.4), p = 0.34) and time to goal feed (6.0 days (3.2–8.3) vs. 6.9 days (5.0–9.0), p = 0.15)). There was no difference in all oral feeds at one year: 88% vs. 98%, p = 0.16. The delayed extubation group performed significantly worse on all measures. Immediate and early extubation displayed no differences in feeding outcomes and length of stay in this study, while delayed extubation performed worse on all measures. Thus, we believe that clinicians should emphasize extubation within 3 days post-surgery to improve feeding outcomes while minimizing time hospitalized.

Trisomy 13 and 18 are common chromosomal abnormalities that affect multiple organ systems. There is a paucity of published data, however, on the hepatic complications seen in these patient populations. One of the most common pathologic hepatobiliary issues seen in the newborn period is direct hyperbilirubinemia (DH). Thus, this study sought to estimate the incidence and evaluate possible etiologies of DH in neonates with trisomy 13 or 18. This retrospective cohort study included all infants admitted to our two neonatal intensive care units between 2012 and 2020 with the diagnosis of trisomy 13 or 18. DH is most commonly diagnosed as a direct bilirubin >1 mg/dl but a cutoff of >2 mg/dl is more specific for cholestasis, so both cutoffs were evaluated. Continuous data were compared using Fisher's exact test and categorical variables by the Mann–Whitney U test. Thirty‐five patients met inclusion: 13 with trisomy 13 and 22 with trisomy 18. DH of >2 mg/dl was seen in seven (53.8%) patients with trisomy 13 and five (22.7%) with trisomy 18. Using a cutoff of >1 mg/dl, the rate of trisomy 13 was unchanged, but the rate in trisomy 18 increased to 9/22 (40.9%). There was a trend toward more DH in trisomy 13 patients (p = 0.079) versus trisomy 18 and higher rates in infants who received total parenteral nutrition (TPN) (50.0 vs. 13.3%, p = 0.026). The presence of cardiac or ultrasound‐defined hepatobiliary abnormalities was not correlated with DH. Due to the high rates of DH in hospitalized neonates with trisomy 13 and 18, we recommend screening newborns with trisomy 13 or 18 for DH starting in the first week of life and continuing at least weekly until 4 weeks of life or until completion of TPN, whichever comes later. Future studies should further evaluate possible etiologies of DH in this population.
