Utility of cephalic drains in infants receiving extracorporeal membrane oxygenation.

INTRODUCTION: The addition of cephalic drains (CDs) in extracorporeal membrane oxygenation (ECMO) to augment venous drainage may offer benefit, though their use is varied. Our objective was to describe our institution's experience with CDs including flow rates and patency. We also compared complication rates between patients with and without a CD. METHODS: This retrospective cohort study included infants <12 months of age cannulated for ECMO between January 1, 2010 and September 30, 2019 at a single institution. Flow data were obtained for those with a CD. Demographic and complication rates were obtained for all. RESULTS: Of 264 patients in the final cohort, 220 (83%) had a CD of which 93.2% remained patent to decannulation. CDs typically provided 30% or more of ECMO flow throughout the ECMO run. The median time to CD clot was 139 h (range 48-635 h). Patients with a clotted CD had longer ECMO runs than those whose CD remained patent (median 382 h [IQR 217-538] vs 139 h [IQR 91-246], p < 0.001). Survival to discharge was lower for those with clotted versus patent CD (14% vs 70%, p < 0.001). Mechanical complications were more common in patients with CD (p = 0.005). Seizures were more common in those without a CD (p = 0.021). CONCLUSIONS: In this cohort, the majority of CDs placed remained patent at decannulation and provided substantial additional venous drainage. Mechanical problems were common in patients with CDs, but without clinical sequelae. Further study is warranted to elucidate CD impact on short- and long-term outcomes.

Medical and surgical interventions and outcomes for infants with trisomy 18 (T18) or trisomy 13 (T13) at children's hospitals neonatal intensive care units (NICUs).

OBJECTIVES: To examine characteristics and outcomes of T18 and T13 infants receiving intensive surgical and medical treatment compared to those receiving non-intensive treatment in NICUs. STUDY DESIGN: Retrospective cohort of infants in the Children's Hospitals National Consortium (CHNC) from 2010 to 2016 categorized into three groups by treatment received: surgical, intensive medical, or non-intensive. RESULTS: Among 467 infants admitted, 62% received intensive medical treatment; 27% received surgical treatment. The most common surgery was a gastrostomy tube. Survival in infants who received surgeries was 51%; intensive medical treatment was 30%, and non-intensive treatment was 72%. Infants receiving surgeries spent more time in the NICU and were more likely to receive oxygen and feeding support at discharge. CONCLUSIONS: Infants with T13 or T18 at CHNC NICUs represent a select group for whom parents may have desired more intensive treatment. Survival to NICU discharge was possible, and surviving infants had a longer hospital stay and needed more discharge supports.

Intraoperative dextrose rate during exploratory laparotomies in neonates and the incidence of postoperative hyperglycemia: A retrospective observational study.

INTRODUCTION: Compared with the older pediatric population, neonates have greater perioperative morbidity and mortality. Difficulty with glucose regulation may be a contributing modifiable risk factor during perioperative anesthetic management. To mitigate the risk of hyperglycemia in neonates, some providers empirically halve the preoperative rate of dextrose-containing infusions during surgery. AIM: To assess the association between halving the preoperative maintenance dextrose rate and postoperative euglycemia in neonatal intensive care unit patients undergoing exploratory laparotomies. METHODS: Neonatal intensive care unit patients who underwent exploratory laparotomy under general anesthesia from 1/1/2014 to 11/21/2019 were included in this analysis. Hyperglycemia and hypoglycemia were defined as >150 mg/dL and <46 mg/dL. A calculated dextrose ratio was utilized to categorize patients into full and half intraoperative dextrose rate cohorts. Univariate analyses were performed with Fisher's exact test, the Wilcoxon rank sum test, or Spearman's correlation. Multivariable analyses with regression models were conducted after graphical evaluation of a predetermined set of independent variables. RESULTS: 107 patients were included in the full dextrose rate cohort and 96 patients in the half dextrose rate cohort with postoperative hyperglycemia occurring in 47 and 28 patients, respectively. On univariate analysis, halving the preoperative dextrose rate was associated with decreased postoperative hyperglycemia (odds ratio: 0.53; 95% CI: 0.28-0.98, P = 0.041). This association continued in the regression model (adjusted odds ratio: 0.49; 95% CI: 0.25-0.80, P = 0.008) after controlling for preoperative dextrose rate, preoperative serum glucose, preoperative pH, surgical duration, postmenstrual age at surgery, and the presence of necrotizing enterocolitis. Only one patient was hypoglycemic postoperatively, and they were in the full dextrose cohort. CONCLUSION: Halving of preoperative dextrose rates intraoperatively during exploratory laparotomy in neonatal intensive care unit patients was associated with a decreased risk of postoperative hyperglycemia without substantially increasing the occurrence of postoperative hypoglycemia. The practice of halving preoperative dextrose rates may be an effective empirical approach for intraoperative glucose management in the high-risk neonatal population when blood glucose monitoring is challenging.

Respiratory Decompensation and Immunization of Preterm Infants.

BACKGROUND: Concern for respiratory decompensation after immunization in premature infants, particularly those with bronchopulmonary dysplasia (BPD), may lead to delayed and altered immunization schedules. METHODS: A retrospective cohort of premature infants at <32 weeks' gestational age cared for in a tertiary level 4 NICU and immunized during their hospital stay were evaluated for respiratory decompensation within 72 hours of immunization. Respiratory measurements including change in respiratory support, mean fraction of inspired oxygen, and apnea, bradycardia, and desaturation events were compared between those infants with BPD and those without. The primary outcome was the difference in respiratory decompensation defined as a composite of increased respiratory support or increased fraction of inspired oxygen ≥10% within 72 hours of immunization. RESULTS: Of 403 infants admitted to the NICU and immunized, 240 met the study criteria. Of those infants, 172 had a diagnosis of BPD. There was no difference in the primary outcome of respiratory decompensation after immunization between groups (P = .65). There was also no significant difference in apnea, bradycardia, and desaturation events between groups (P = .51). CONCLUSIONS: In this cohort, respiratory decompensation requiring clinical intervention after immunization of preterm infants both with and without BPD was uncommon and not significantly different between groups. Consideration for immunization of this vulnerable population should not be delayed out of concern for clinical deterioration.

The ethical debate of maternal choice and autonomy in cesarean delivery.

Cesarean delivery as a result of maternal request is increasingly popular, leading to important ethical questions. One of the challenging issues is balancing respect for the autonomy of a pregnant woman with concerns of beneficence and nonmaleficence for her and the fetus. The perceived benefit of cesarean section is protection of the pelvic floor. Increased rates of respiratory morbidity in infants born by cesarean section cannot be ignored. Societal concerns of distribution of resources must be considered in ongoing discussions of this critical issue. This article reviews the current ethical debate of maternal choice and autonomy in elective cesarean delivery.
