Safety and accuracy of neonatal continuous glucose monitoring.

BACKGROUND: Hypoglycemia is a significant problem for all neonates and requires minimally invasive and reliable monitoring. The primary objective of this study was to verify the safety and accuracy of the continuous glucose monitoring (CGM) of full-term neonates using Freestyle Libre, a flash glucose monitoring (FGM) device. METHODS: The study was conducted on 20 neonates. Shortly after birth, we placed the FGM sensor on the outside of the neonates' thighs. We scanned the CGM values at 60, 120, 180, and 360 min after birth and simultaneously obtained blood glucose values with plantar capillaries by heel puncture. The neonates wore the sensors for up to 6 h and then they were removed. RESULTS: Of the 75 data points to be measured, 65 points (86.7%) were obtained by scan. There was no change in the sensor attachment site in 12 of 18 completed cases in this study but we observed slight induration in four cases (22.2%) and slight redness in one case (5.5%) at the sensor puncture site. A moderate correlation was observed between the CGM and blood glucose values. The CGM values tended to be low at 120, 180, and 360 min after birth, and tended to be high only at 60 min after birth. CONCLUSIONS: The CGM device was safe to wear on the neonate and the CGM data correlated well with blood glucose levels. There was dissociation between CGM data and blood glucose levels in the acute period soon after birth when the blood glucose levels changed rapidly.

Intestinal volvulus in utero causing torsion of dilated bowel with ileal atresia: a case report.

BACKGROUND: In utero intestinal volvulus with intestinal atresia is a rare and life-threatening condition that can cause torsion of the dilated bowel. The management and outcomes of this disease remain unclear. CASE PRESENTATION: A 19-year-old woman noticed a decrease in fetal motion at 35 weeks. Fetal ultrasound showed dilated fetal bowel and the whirlpool sign. The patient was referred to our hospital for an emergency cesarean section. The neonate's abdomen was dark and severely distended, and a laparotomy was performed. Necrotic ileum and cord-type intestinal atresia (Type II) were observed in the dilated terminal ileum. The necrotic ileum was resected, and a second-look surgery was performed the following day. Then, we anastomosed the remaining intestine, and the total intestine length was 52 cm. There were no surgical complications, and the patient was discharged without requiring total parenteral nutrition or fluid infusion. The patient's height and weight were within the - 2 standard deviation range of the growth curve at 5 months. CONCLUSIONS: Emergency and appropriate management of intestinal volvulus in utero causing torsion of the dilated bowel resulted in good outcomes in a patient with intestinal atresia. Perinatal physicians should be aware of this emergency condition and plan their treatment approach accordingly.
