Assessing the Impact of Nasotracheal Intubation on Postoperative Neonates With Congenital Heart Disease: A Quality Improvement Project at a Single Heart Center.

OBJECTIVES: Nasotracheal intubation (NTI) is associated with fewer unplanned extubations and improved oral motor skills compared with orotracheal intubation (OTI). Our study aimed to implement a practice change from OTI to NTI for neonatal cardiac surgery and assess impact on postoperative outcomes. DESIGN: Single-center, prospective, quality improvement study. SETTING: Academic children's hospital. PATIENTS: One hundred thirty neonates undergoing cardiac surgery with cardiopulmonary bypass. INTERVENTIONS: NTI during index cardiac surgery. MEASUREMENTS AND MAIN RESULTS: Data were collected between January 2019 and April 2021. The study was implemented in three phases: retrospective: OTI neonates ( n = 43), I: safety and feasibility of NTI ( n = 17), and II: speech language pathology (SLP) evaluation on postoperative day 1 facilitated by NTI ( n = 70). Retrospective and phase I patients were combined for analysis. Groups were compared using Kruskal-Wallis test or Wilcoxon rank-sum test.Ninety-one percent of eligible neonates were nasotracheally intubated. There were no clinically significant complications. Days to first SLP encounter decreased from a median 4.5 days (interquartile range [IQR], 3.8-6.2) to 1.1 days (IQR, 1.0-1.9; p < 0.001). Oral readiness time decreased from a median of 6.6 days (IQR, 5.4-8.9) to 4.3 days (IQR, 3.4-8.6; p < 0.001). . CONCLUSIONS: NTI is feasible and safe in neonatal cardiac surgery. System-level engagement with stakeholders is necessary to change clinical practice. NTI facilitates early SLP evaluation and treatment and significantly affects oral readiness after neonatal cardiac surgery.

Assessment and management of feeding difficulties for infants with complex CHD.

Early surgical intervention in infants with complex CHD results in significant disruptions to their respiratory, gastrointestinal, and nervous systems, which are all instrumental to the development of safe and efficient oral feeding skills. Standardised assessments or treatment protocols are not currently available for this unique population, requiring the clinician to rely on knowledge based on neonatal literature. Clinicians need to be skilled at evaluating and analysing these systems to develop an appropriate treatment plan to improve oral feeding skill and safety, while considering post-operative recovery in the infant with complex CHD. Supporting the family to re-establish their parental role during the hospitalisation and upon discharge is critical to reducing parental stress and oral feeding success.

Disruptions in the development of feeding for infants with congenital heart disease.

Congenital heart disease (CHD) is the most common birth defect for infants born in the United States, with approximately 36,000 affected infants born annually. While mortality rates for children with CHD have significantly declined, there is a growing population of individuals with CHD living into adulthood prompting the need to optimise long-term development and quality of life. For infants with CHD, pre- and post-surgery, there is an increased risk of developmental challenges and feeding difficulties. Feeding challenges carry profound implications for the quality of life for individuals with CHD and their families as they impact short- and long-term neurodevelopment related to growth and nutrition, sensory regulation, and social-emotional bonding with parents and other caregivers. Oral feeding challenges in children with CHD are often the result of medical complications, delayed transition to oral feeding, reduced stamina, oral feeding refusal, developmental delay, and consequences of the overwhelming intensive care unit (ICU) environment. This article aims to characterise the disruptions in feeding development for infants with CHD and describe neurodevelopmental factors that may contribute to short- and long-term oral feeding difficulties.

The association between feeding protocol compliance and weight gain following high-risk neonatal cardiac surgery.

BACKGROUND: Children with congenital heart disease are at high risk for malnutrition. Standardisation of feeding protocols has shown promise in decreasing some of this risk. With little standardisation between institutions' feeding protocols and no understanding of protocol adherence, it is important to analyse the efficacy of individual aspects of the protocols. METHODS: Adherence to and deviation from a feeding protocol in high-risk congenital heart disease patients between December 2015 and March 2017 were analysed. Associations between adherence to and deviation from the protocol and clinical outcomes were also assessed. The primary outcome was change in weight-for-age z score between time intervals. RESULTS: Increased adherence to and decreased deviation from individual instructions of a feeding protocol improves patients change in weight-for-age z score between birth and hospital discharge (p = 0.031). Secondary outcomes such as markers of clinical severity and nutritional delivery were not statistically different between groups with high or low adherence or deviation rates. CONCLUSIONS: High-risk feeding protocol adherence and fewer deviations are associated with weight gain independent of their influence on nutritional delivery and caloric intake. Future studies assessing the efficacy of feeding protocols should include the measures of adherence and deviations that are not merely limited to caloric delivery and illness severity.

Developmental Care for Hospitalized Infants With Complex Congenital Heart Disease: A Science Advisory From the American Heart Association.

Developmental disorders, disabilities, and delays are a common outcome for individuals with complex congenital heart disease, yet targeting early factors influencing these conditions after birth and during the neonatal hospitalization for cardiac surgery remains a critical need. The purpose of this science advisory is to (1) describe the burden of developmental disorders, disabilities, and delays for infants with complex congenital heart disease, (2) define the potential health and neurodevelopmental benefits of developmental care for infants with complex congenital heart disease, and (3) identify critical gaps in research aimed at evaluating developmental care interventions to improve neurodevelopmental outcomes in complex congenital heart disease. This call to action targets research scientists, clinicians, policymakers, government agencies, advocacy groups, and health care organization leadership to support funding and hospital-based infrastructure for developmental care in the complex congenital heart disease population. Prioritization of research on and implementation of developmental care interventions in this population should be a major focus in the next decade.

Label-free ferrohydrodynamic cell separation of circulating tumor cells.

Circulating tumor cells (CTCs) have significant implications in both basic cancer research and clinical applications. To address the limited availability of viable CTCs for fundamental and clinical investigations, effective separation of extremely rare CTCs from blood is critical. Ferrohydrodynamic cell separation (FCS), a label-free method that conducted cell sorting based on cell size difference in biocompatible ferrofluids, has thus far not been able to enrich low-concentration CTCs from cancer patients' blood because of technical challenges associated with processing clinical samples. In this study, we demonstrated the development of a laminar-flow microfluidic FCS device that was capable of enriching rare CTCs from patients' blood in a biocompatible manner with a high throughput (6 mL h-1) and a high rate of recovery (92.9%). Systematic optimization of the FCS devices through a validated analytical model was performed to determine optimal magnetic field and its gradient, ferrofluid properties, and cell throughput that could process clinically relevant amount of blood. We first validated the capability of the FCS devices by successfully separating low-concentration (∼100 cells per mL) cancer cells using six cultured cell lines from undiluted white blood cells (WBCs), with an average 92.9% cancer cell recovery rate and an average 11.7% purity of separated cancer cells, at a throughput of 6 mL per hour. Specifically, at ∼100 cancer cells per mL spike ratio, the recovery rates of cancer cells were 92.3 ± 3.6% (H1299 lung cancer), 88.3 ± 5.5% (A549 lung cancer), 93.7 ± 5.5% (H3122 lung cancer), 95.3 ± 6.0% (PC-3 prostate cancer), 94.7 ± 4.0% (MCF-7 breast cancer), and 93.0 ± 5.3% (HCC1806 breast cancer), and the corresponding purities of separated cancer cells were 11.1 ± 1.2% (H1299 lung cancer), 10.1 ± 1.7% (A549 lung cancer), 12.1 ± 2.1% (H3122 lung cancer), 12.8 ± 1.6% (PC-3 prostate cancer), 11.9 ± 1.8% (MCF-7 breast cancer), and 12.2 ± 1.6% (HCC1806 breast cancer). Biocompatibility study on H1299 cell line and HCC1806 cell line showed that separated cancer cells had excellent short-term viability, normal proliferation and unaffected key biomarker expressions. We then demonstrated the enrichment of CTCs in blood samples obtained from two patients with newly diagnosed advanced non-small cell lung cancer (NSCLC). While still at its early stage of development, FCS could become a complementary tool for CTC separation for its high recovery rate and excellent biocompatibility, as well as its potential for further optimization and integration with other separation methods.

Speech development of children with cleft palate before and after palatal surgery.

OBJECTIVE: This study examined the speech production abilities of children with cleft palate before and after palate repair. PARTICIPANTS: Twenty-eight children participated in the study, 14 with cleft palate and 14 without clefts matched for age, gender, and mothers' educational level. MAIN OUTCOME MEASURES: Comparisons were made between the children with cleft palate before and after surgery for canonical babbling ratios, size of consonant inventories, place and manner characteristics, and early developing sounds [p, b, t, d, k, g, m, n, eta]. Also, comparisons were made between the children with cleft palate and their peers without clefts at postsurgery/17 months for the measures described above. RESULTS: Paired t tests revealed differences in pre- and postsurgery performance of the children with cleft palate for production of canonical syllables and size of consonant inventories. Although no significant differences were noted for place and manner features, production of oral stops doubled from the time before surgery to that after surgery. Specifically, production of the bilabial stop [b] showed significant change over time. Results of independent t tests indicated no difference between groups for production of canonical syllables and size of consonant inventories at 17 months. However, significant group differences were noted for production of stops, oral stops, nasals, glides, and alveolars. The children without clefts produced more stops, oral stops, and alveolars. In contrast, more nasals and glides were seen in the vocalizations of the children with cleft palate. CONCLUSIONS: Children with cleft palate made gains in production of canonical syllables and size of consonant inventories postsurgery; however, they continued to show deficits in production of stops and alveolar place features.
