Characteristics of infants admitted with hypoglycemia to a neonatal unit

Determinants of neonatal hypoglycemia among neonates admitted at Hiwot Fana Comprehensive Specialized University Hospital, Eastern Ethiopia: A retrospective cross-sectional study

Objective

The study aimed to assess the magnitude and determinants of neonatal hypoglycemia among neonates admitted to the Neonatal Intensive Care Unit at Hiwot Fana Specialized University Hospital, Eastern Ethiopia.

Methods

An institutional-based cross-sectional study was conducted among 698 randomly selected neonates at Hiwot Fana Comprehensive Specialized Hospital from 1 January 2018 to 31 December 2020. By looking at the charts, data were gleaned from the medical records. Data were entered into Epi-Data version 3.1 and analysis was performed using SPSS version 22. Bivariable and multivariable logistic regression analyses were conducted to identify determinant factors of neonatal hypoglycemia. Association was described using an adjusted odds ratio along with a 95% CI. Finally, a p-value <0.05 in the adjusted analysis was considered to declare a statistically significant association.

Results

Out of 698 neonates, 148 (21.2%; 95% CI: 18.3, 24.5) neonates had hypoglycemia. Preterm birth (AOR = 3.06; 95% CI: 1.02, 9.17), hypothermia (AOR = 2.65; 95% CI: 1.22, 5.75), neonatal sepsis (AOR = 2.61; 95% CI: 1.03, 6.59), diabetic mother (AOR = 2.34; 95% CI: 1.03, 5.33), and delay in initiation of breastfeeding for more than 1 h (AOR = 3.89; 95% CI: 1.17, 12.89) were identified as determinant factors of neonatal hypoglycemia.

Conclusion

The magnitude of neonatal hypoglycemia was quite common among neonates. Neonatal hypoglycemia was found to be predicted by preterm birth, hypothermia, neonatal sepsis, maternal diabetes mellitus, and delay in starting nursing. We therefore strongly suggest health-care workers work in the postnatal unit to manage and control these and other determinant factors of hypoglycemia to prevent the occurrence of neonatal hypoglycemia.

Indications for intensive care unit treatment among neonates born to mothers with thyroid disease: A population-based cohort study

INTRODUCTION

Thyroid diseases in pregnancy are relatively common and are associated with adverse pregnancy and perinatal outcomes, increasing a neonate's risk of admission to the neonatal intensive care unit (NICU). The aim of this study was to evaluate the indications for increased risk of NICU admission among the neonates of hypothyroid and hyperthyroid mothers.

MATERIAL AND METHODS

The study data consisted of all singleton deliveries (n = 734 773) between 2004 and 2016 in Finland collected from the Finnish Medical Birth Register. The odds of NICU admission (with 95% confidence intervals) were compared between the neonates of hypothyroid or hyperthyroid mothers and of mothers without any thyroid diseases by specified neonatal characteristics and morbidities using logistic regression analysis. The studied neonatal characteristics were preterm birth (<37+0 gestational weeks), low birthweight (<2500 g), the rate of small- and large-for-gestational age infants, and eight disease-specific neonatal outcomes: asphyxia, respiratory distress syndrome, meconium aspiration syndrome, pneumothorax, cardiovascular problems, infections, jaundice and hypoglycemia.

RESULTS

The most common indications for NICU care were principally the same in the neonates of the mothers with and without thyroid disease: respiratory distress syndrome, infections, preterm birth, low birthweight and neonatal hypoglycemia. The preterm neonates, neonates with low birthweight, and large-for-gestational-age infants had increased odds of NICU admission if their mother had hypothyroidism. Also neonates with cardiovascular problems, jaundice or hypoglycemia associated with maternal diabetes had increased odds of NICU admissions if their mother had hypothyroidism. Further, the preterm neonates, large-for-gestational-age infants, and term infants with jaundice had increased odds of NICU admission if their mother had hyperthyroidism.

CONCLUSIONS

The most common indications for NICU care were similar for the neonates of the mothers with and without thyroid disease. However, the neonates of the mothers with thyroid diseases were more likely to need NICU care. The neonates of the mothers with thyroid diseases had higher odds of NICU treatment in cases of preterm birth, large for gestational age, and hypoglycemia.

Implementation of dextrose gel in the management of neonatal hypoglycaemia

AIM

The aim of this study was to evaluate dextrose gel in the management of neonatal hypoglycaemia in the postnatal wards at an Australian tertiary level perinatal centre.

METHODS

An audit was performed before and after implementation of dextrose gel. Pre-implementation, neonatal hypoglycaemia was managed with feed supplementation alone, and dextrose gel was used in addition to feed supplementation in the post-implementation phase. Outcomes included admission to neonatal intensive care unit (NICU) for management of hypoglycaemia, proportion of neonates who achieved normoglycaemia (defined as blood glucose ≥2.6 mmol/L, with no clinical signs after one or two treatment attempts) and proportion of neonates with hypoglycaemia recurrence after normoglycaemia and one or two treatment attempts.

RESULTS

NICU admission for treatment of hypoglycaemia reduced significantly post-implementation of dextrose gel (29/100 (29%) vs. 14/100 (14%), P = 0.01). No significant difference was seen in the proportion of neonates achieving normoglycaemia (71/100 (71%) vs. 75/100 (75%), P = 0.52), but hypoglycaemia recurrence was higher in the post-implementation group (22/71 (31%) vs. 37/75 (49%), P = 0.02).

CONCLUSIONS

Dextrose gel is effective in the management of neonatal hypoglycaemia in the postnatal ward setting, reducing admission to NICU and mother-infant separation.

Cardiac intensive care for the neonate and child after cardiac surgery

PURPOSE OF REVIEW

The focus of postoperative care in the pediatric patient with congenital heart disease has become a reduction in length of stay and morbidity. This review will discuss strategies to achieve this goal and recent studies to support current practices.

RECENT FINDINGS

Most agree that prolongation of the length of stay following a cardiac surgery contributes to morbidity. Postoperative feeding difficulty, hyperglycemia, acute kidney injury, fluid overload, and prolonged intubation contribute significantly to length of stay.

SUMMARY

Postoperative care of the neonate and child following a cardiac surgery remains challenging with limited data to drive our practices. Patients remain at risk for significant morbidity, and future studies should focus on recognizing predictors of morbidity, prevention, and treatment.

Tight glycemic control after pediatric cardiac surgery in high-risk patient populations: a secondary analysis of the safe pediatric euglycemia after cardiac surgery trial

BACKGROUND

Our previous randomized, clinical trial showed that postoperative tight glycemic control (TGC) for children undergoing cardiac surgery did not reduce the rate of health care-associated infections compared with standard care (STD). Heterogeneity of treatment effect may exist within this population.

METHODS AND RESULTS

We performed a post hoc exploratory analysis of 980 children from birth to 36 months of age at the time of cardiac surgery who were randomized to postoperative TGC or STD in the intensive care unit. Significant interactions were observed between treatment group and both neonate (age ≤30 days; P=0.03) and intraoperative glucocorticoid exposure (P=0.03) on the risk of infection. The rate and incidence of infections in subjects ≤60 days old were significantly increased in the TGC compared with the STD group (rate: 13.5 versus 3.7 infections per 1000 cardiac intensive care unit days, P=0.01; incidence: 13% versus 4%, P=0.02), whereas infections among those >60 days of age were significantly reduced in the TGC compared with the STD group (rate: 5.0 versus 14.1 infections per 1000 cardiac intensive care unit days, P=0.02; incidence: 2% versus 5%, P=0.03); the interaction of treatment group by age subgroup was highly significant (P=0.001). Multivariable logistic regression controlling for the main effects revealed that previous cardiac surgery, chromosomal anomaly, and delayed sternal closure were independently associated with increased risk of infection.

CONCLUSIONS

This exploratory analysis demonstrated that TGC may lower the risk of infection in children >60 days of age at the time of cardiac surgery compared with children receiving STD. Meta-analyses of past and ongoing clinical trials are necessary to confirm these findings before clinical practice is altered.

Hypoglycemia in Prader-Willi syndrome

Although mouse models of Prader-Willi syndrome (PWS) suggest that hypoglycemia may be part of this syndrome, review of the literature shows little evidence that it is an issue in humans with PWS. Both adrenal and growth hormone deficiency can be seen in PWS, and both of these hormone deficiencies are associated with increased risk for hypoglycemia. We reviewed medical records for patients with PWS seen at the University of Florida Prader-Willi Program. Children were 2 months to 5 years of age. We recorded the presence, degree, and persistence of hypoglycemia, age of first occurrence, genetic diagnosis, and gestational age. Repeated hypoglycemia was determined if individuals had multiple blood glucose (BG) values <50 mg/dl before 1 month old, or BG levels <50 mg/dl once and additional BG values <70 mg/dl after 1 year of age. Of 95 patient charts reviewed, 12 (12.6%) had recorded hypoglycemia. Six of 12 patients with hypoglycemia had documented BG levels <40 mg/dl. Seven had their first episode of hypoglycemia within the first day of life. Of these seven individuals, five had BG <40 mg/dl. Repeated hypoglycemia was noted in 10 patients (83% of all patients with hypoglycemia). Only two with hypoglycemia had documented adrenal insufficiency. Our study suggests that infants with PWS may be predisposed to hypoglycemia from birth. Additional investigation is necessary to confirm our findings and define the cause of hypoglycemia. If the presence of hypoglycemia is confirmed, early detection and treatment may result in improved neurocognitive outcomes.
