Intravenous paracetamol in comparison with ibuprofen for the treatment of patent ductus arteriosus in preterm infants: a randomized controlled trial.

Our aim was to assess the efficacy and safety of intravenous (i.v.) paracetamol vs. i.v. ibuprofen for the treatment of hemodynamically significant patent ductus arteriosus (hsPDA) in preterm infants. This is a multicenter randomized controlled study. Infants with a gestational age of 25+0-31+6 weeks were randomized to receive i.v. paracetamol (15 mg/kg/6 h for 3 days) or i.v. ibuprofen (10-5-5 mg/kg/day). The primary outcome was the closure rate of hsPDA after the first treatment course with paracetamol or ibuprofen. Secondary outcomes included the constriction rate of hsPDA, the re-opening rate, and the need for surgical closure. Fifty-two and 49 infants received paracetamol or ibuprofen, respectively. Paracetamol was less effective in closing hsPDA than ibuprofen (52 vs. 78%; P = 0.026), but the constriction rate of the ductus was similar (81 vs. 90%; P = 0.202), as confirmed by logistic regression analysis. The re-opening rate, the need for surgical closure, and the occurrence of adverse effects were also similar.Conclusions: Intravenous paracetamol was less effective in closing hsPDA than ibuprofen, but due to a similar constriction effect, its use was associated with the same hsPDA outcome. These results can support the use of i.v. paracetamol as a first-choice drug for the treatment of hsPDA.Trial registration: Clinicaltrials.gov : NCT02422966, Date of registration: 04/09/2015; EudraCT no: 2013-003883-30. What is Known: • The successful closure of patent ductus arteriosus with oral paracetamol has been recently reported in several preterm infants, but only one randomized controlled study investigated the efficacy of intravenous paracetamol. What is New: • Intravenous paracetamol is less effective in closing hsPDA than ibuprofen, but have a similar constriction effect. • These results can support the use of i.v. paracetamol as a first-choice drug for the treatment of hsPDA.

Proactive enteral nutrition in moderately preterm small for gestational age infants: a randomized clinical trial.

OBJECTIVE: To investigate the efficacy of a proactive feeding regimen (PFR) in reducing hospital length of stay in a population of moderately preterm small for gestational age (SGA) infants. STUDY DESIGN: SGA infants (z-score <-1.28) of gestational age (GA) 32-36 weeks and birth weight (BW) >1499 g were allocated at random to receive either a PFR, starting with 100 mL/kg/day and gradually increasing to 200 mL/kg/day by day 4, or a standard feeding regimen, starting with 60 mL/kg/day and gradually increasing to 170 mL/kg/day by day 9. All infants received human milk. RESULTS: A total of 72 infants were randomized to the 2 groups, 36 to the PFR group (mean GA, 35.1 ± 0.7 weeks; mean BW, 1761 ± 177 g) and 36 to the standard feeding regimen group (mean GA, 35.5 ± 1.2 weeks; mean BW, 1754 ± 212 g). Infants in the PFR group were discharged significantly earlier (mean, 9.8 ± 3.1 days vs 11.9 ± 4.7 days; P = .029). The need for intravenous fluids (2.8% vs 33.3%; P = .0013) and the incidence of hypoglycemia (0 vs 33.3%; P = .00016) were significantly lower in the PFR group. Feeding intolerance and fecal calprotectin levels did not differ between the 2 groups. CONCLUSION: A PFR in moderately preterm SGA infants is well tolerated and significantly reduces both the length of stay and the risk of neonatal hypoglycemia.

Neonatal lung ultrasonography score after surfactant in preterm infants: A prospective observational study.

OBJECTIVE: To assess changes in neonatal lung ultrasonography score (nLUS) after surfactant administration in preterm infants with respiratory distress syndrome (RDS). WORKING HYPOTHESIS: The reduction of nLUS score before (nLUSpre), 2 hours (nLUS2h), and 12 hours (nLUS12h) after surfactant administration to identify patients who will not need a second treatment. STUDY DESIGN AND SETTING: Prospective observational study in the tertiary neonatal intensive care unit. PATIENTS SELECTION: Forty-six preterm neonates with RDS of 32 weeks median gestational age (IQR 30-33) and mean birth weight of 1650 ± 715 g. METHODOLOGY: Lung ultrasonography was performed before, 2 hours, and 12 hours after surfactant administration in preterm infants with RDS needing surfactant treatment. Resulting nLUS was analyzed. RESULTS: The Wilcoxon signed-rank test demonstrated an nLUS lowering after 2 hours (P < .001) and 12 hours (P < .001) from surfactant administration. Sixteen newborns required surfactant retreatment with median gestational age of 32 weeks (IQR 29-33) and mean birth weight of 1519 ± 506 g.The receiver operating characteristic analysis for the nLUS2h yielded an area under the curve of 0.80 (95% confidence interval, 0.76-0.85; P < .001). A nLUS2h ≥7 showed a sensitivity of 94% and a specificity of 60% for needing a second treatment with surfactant. CONCLUSIONS: In preterm infants with RDS requiring surfactant treatment, nLUS evaluated 2 hours after surfactant administration can be used to identify patients who will not need a second treatment.

Reliability of two different bedside assays for C-reactive protein in newborn infants.

BACKGROUND: Bedside tests for C-reactive protein (CRP) have been studied in pediatric patients, but not in neonates. METHODS: This study compared the results of two rapid bedside tests for CRP (Quick-Read CRP, Orion Diagnostic, Espoo, Finland and NycoCard CRP-Single Test, Axis-Shield, Oslo, Norway) with those of our central laboratory method (CRP-Lab) in newborn infants. CRP concentrations were determined using 72 samples obtained from 43 infants with suspected sepsis occurring between 1 and 28 days of life. RESULTS: Considering positive CRP concentrations to be > or = 10 mg/L, both bedside tests had good specificity (Quick-Read 80.5%, NycoCard 83.3%) and sensitivity (Quick-Read 97.2%, NycoCard 94.4%) when compared with our CRP-Lab. The agreement of measurement with central laboratory values was high for both the bedside tests, without statistically significant differences between the methods. The Quick-Read and NycoCard methods did not show any statistically significant systematic proportional bias when compared with the central laboratory values. The accuracy of the results of both bedside tests is somewhat decreased when CRP concentrations are >100 mg/L. CONCLUSIONS: This study shows that both the Quick-Read and the NycoCard test can be used for serial determinations of CRP concentrations in newborn infants. They require small volumes of blood and provide reliable results in < 5 min.

Neonatal transient pseudohypoparathyroidism: could it be included among inactivating parathyroid hormone (PTH)/PTH-related protein signalling disorders?

We report a case of transient pseudohypoparathyroidism in a full-term newborn that presented at 20 hours of life with hypocalcemic seizures, hyperphosphatemia and raised parathormone levels. The diagnosis of pseudohypoparathyroidism was made according to biochemical investigations. The infant was treated with calcium supplementation and vitamin D analog therapy, and he remained stable and symptom-free with normal serum biochemistries during follow-up. We suggest that transient pseudohypoparathyroidism of the newborn (ntPHP) might be included among inactivating parathyroid hormone (PTH)/PTH-related protein signaling disorders as defined by the classification schema recently proposed by the European Pseudohypoparathyroidism Network. To the best of our knowledge, this is the first report in which the new classification has been applied to a case of ntPHP.

A modified physiologic test for bronchopulmonary dysplasia: a clinical tool for weaning from CPAP and/or oxygen-therapy the premature babies?

BACKGROUND: A physiologic test for estimating BPD rate has been developed by Walsh and collaborators. Actually there are not standard criteria for weaning from CPAP and/or oxygen therapy the premature babies. Aim of this study was to verify if a physiologic test, modified respect to that developed by Walsh and collaborators for estimating BPD rate, can be used as a clinical tool for weaning the premature babies from CPAP and/or oxygen therapy. METHODS: Neonates with BW 500-1250 g and GA ≤ 32 weeks, receiving FiO2 ≤ 0.30 by hood or CPAP, were prospectively studied at 28 days of life and at 36 weeks of postmestrual age. The test was performed in 3 steps: baseline, challenge (FiO2 and CPAP reduction to room air) and post test (room air). Monitoring of transcutaneous CO2 was added to SpO2 and the newborns passing the test were left in room air. RESULTS: Six of 23 tested babies (26%) passed the challenge at 28 days of life, 4 of 10 tested babies (40%) passed the challenge at 36 weeks. Median values of SpO2 were significantly higher in the neonates passing the test, respect to the failing patients. At the same time median values of TcPCO2 were significantly higher in the latter babies. CONCLUSION: TcPCO2 monitoring appeared to be a new useful parameter for failure prediction of weaning. The test represented a clinical guide because the newborns passing it were left in room air.

Secretory phospholipase A2 and neonatal respiratory distress: pilot study on broncho-alveolar lavage.

PURPOSES: Secretory phospholipase A2 hydrolyzes phosphoglycerides and it has been shown to be involved in alveolar inflammation and surfactant degradation. It plays an important role in acute lung injury but it has never been studied in newborn infants. We were aimed to investigate the phospholipase A2 activity in neonatal lung injury and its relationship with ventilatory findings. SETTING: Third level university hospital NICU. METHODS: We measured phospholipase activity in broncho-alveolar lavage fluid of 21 neonates with hyaline membrane disease, 10 with pneumonia or sepsis and 10 controls, ventilated for extrapulmonary reasons. Fluid was obtained before surfactant administration on the first day of life and phospholipase activity was measured using an ultrasensitive enzymatic method. Before lavage, lung mechanics in pressure controlled synchronized intermittent mandatory ventilation was analyzed. RESULTS: Phospholipase A2 was higher in babies ventilated for sepsis/pneumonia compared to hyaline membrane disease and to control babies. Phospholipase correlated negatively with dynamic compliance, positively with inspired oxygen fraction, mean airway pressure and oxygenation index. These correlations still remained significant after multivariate analysis, adjusting for possible confounding factors. Phospholipase was not correlated with blood and alveolar pH, gestational age, birth weight, blood gases, Apgar score, tidal volume, surfactant need and ventilation time. CONCLUSIONS: These are the first data about phospholipase A2 in neonates. The enzyme plays a role in neonatal lung injury, especially in infection related respiratory failure. It is associated with lung stiffness, higher mean airway pressure and need for oxygen.

Predicting respiratory distress syndrome in neonates from mothers with intrahepatic cholestasis of pregnancy.

OBJECTIVE: Intrahepatic cholestasis of pregnancy (ICP) has been associated with prematurity and fetal mortality. Recently, ICP has also been recognised as a risk factor for neonatal respiratory distress syndrome (RDS) in term or near-term neonates. Since fetal mortality is more frequent in pregnancies with an early ICP onset, we speculated that the time of exposure (ET) to maternal bile acids at the delivery (BAdeliv) could be involved in neonatal lung damage too. Study aim was to develop a scoring system to predict the RDS occurrence. DESIGN: We conducted a retrospective analysis of 77 pregnancies complicated by ICP (years 2000-2004) looking for factors associated to the neonatal RDS. We developed a risk score as follows: RDS risk score=BAdeliv x ET/gestational age and we prospectively applied it to 30 neonates from ICP pregnancies (years 2005-2006). RESULTS: ROC analysis indicated 9 as the score with the highest sensitivity (83.3%) and specificity (87.5%). Considering a RDS incidence of about 25% in babies coming from ICP pregnancies, the post-test probability showed a risk increased to 66.7% with a score>9 and reduced to 4.8% with a score

Heterologous assisted reproduction and kernicterus: the unlucky coincidence reveals an ethical dilemma.

Secrecy and anonymity related to heterologous assisted reproduction may hide basic newborn data to neonatologists. Secrecy and anonymity are discussed in view of their possible consequences on relational dynamics and on developmental psychology. Nevertheless, they can also involve the offspring's genetic status regarding inheritable diseases. International guidelines have been recently published on this topic. Because no guidelines are 'ideal' unfortunate and possibly dramatic consequences can occur. We aimed to embark on a debate about this matter starting with a real clinical experience. In our case a rarely fatal but widespread disease, together with the lack of knowledge about parental status led, in a fast succession of clinical events, to the unavoidable insurgence of kernicterus.

The joint use of human and electronic eye: visual assessment of jaundice and transcutaneous bilirubinometry.

Our aim was to study the usefulness of jaundice visual assessment combined with skin bilirubin determination in 517 healthy newborns. Yellowness assessment was made and babies were included in three different bilirubin classes. Skin bilirubin and total serum bilirubin were determined within 10 minutes from the visual assessment. This latter led to underestimation of serum bilirubin in 16.7-40.4% and overestimation in 4.9-35.7% of newborns. Skin bilirubin measurement after the visual assessment decreased the risk of underestimation to 0-9.2% and the risk of overestimation to 2.1-11.1%. The majority of visual assessment errors were performed in the more lighted hours of the morning (75%), while the smallest number (39%) occurred during the afternoon. Skin bilirubin measurement significantly corrected these diagnostic errors (p < 0.001, p < 0.02) without differences during the day. Clinical estimate is unreliable for evaluating the need for serum bilirubin assay. Using the addition of skin bilirubin determination is a more advisable approach.

The Long-Term Efficacy of a Galactagogue Containing Sylimarin-Phosphatidylserine and Galega on Milk Production of Mothers of Preterm Infants.

AIMS: To investigate the efficacy of a galactagogue, containing Sylimarin-phosphatidylserine (SILITIDIL) and galega consumed in the first month after delivery by mothers of preterm infants, in maintaining milk production during the first 3-6 months after delivery. MATERIALS AND METHODS: Mothers of infants born at gestational age (GA) between 27 and 32 weeks, enrolled in our previous prospective, double-blind, randomized trial and randomly allocated to receive either the galactagogue (GG) or a placebo (PG), were asked about their milk production at 3 and 6 months after delivery. RESULTS: Of the 100 mothers involved in this study, 45 of GG and 44 of PG responded comprehensively to the questions asked. At the third month after delivery, exclusive human milk administration was reported by 22 mothers of GG and 12 mothers of PG (p < 0.05), whereas 29 mothers of GG and 18 mothers of PG were able to administer >50% of the amount of milk assumed. At the sixth month of life, only eight infants received exclusive human milk (six and two of GG and PG, respectively), and the data are not sufficient for a meaningful clinical evaluation. CONCLUSIONS: It is assumed that a galactagogue during the first month after delivery improves human milk administration to preterm neonates after discharge and for the first 3 months of life.

Semipermeable membranes and hypernatremic dehydration in preterms. A randomized-controlled trial.

BACKGROUND: Hypernatremic dehydration is a complication of preterm infants with reportedly high morbility. In preterm infants, this happens due to a combination of low fluid intake, transepidermal water loss (TEWL), and immaturity of kidney function. Semipermeable membranes are self-adhesive membranes that can be applied as an artificial skin to reduce TEWL. AIMS: To test the hypothesis that early application of a semipermeable membrane (Tegaderm™) in preterm infants ≤30 weeks could result in a significant reduction of hypernatremia (serum Na > 145 mEq/l) during the first 15 days of life. STUDY DESIGN: Randomized controlled trial (UMIN000010515). SUBJECTS: 164 consecutive newborns with gestational age ≤ 30 weeks, absence of congenital skin defects, and duration of admission ≥ 15 days. Patients were randomized to receive semipermeable membrane (n = 82) or no membrane (n = 82) for the first 15 days of life. OUTCOME MEASURES: The primary endpoint of the study was the incidence reduction of hypernatremia (Na > 145 mEq/l). Secondary endpoints included: postnatal weight loss (WL) and time to birth weight (BW) recovery. RESULTS: Incidence of hypernatremia in the control and semipermeable membrane group was 59.7% and 41.6%, respectively (p = 0.030). Postnatal WL was larger in the control group (13.9 ±â€¯5.6% vs 11.1 ±â€¯3.4%, p = 0.005) and occurred later than the semipermeable membrane group (5.4 ±â€¯2.3 vs 4.5 ±â€¯1.4 days, p = 0.005). Time to BW recovery was also longer for control group (13.5 ±â€¯4.3 vs 11.9 ±â€¯3.2 days, p = 0.016). CONCLUSIONS: Early application of skin semipermeable membrane to ≤30 week preterm is associated with decreased incidence of hypernatremia, decreased %WL, and earlier BW recovery. No complications were observed with membrane application.

Continuous glucose monitoring (CGM) in very low birth weight newborns needing parenteral nutrition: validation and glycemic percentiles.

BACKGROUND: Continuous glucose monitoring using subcutaneous sensors is useful in the management of glucose control in neonatal intensive care. We evaluated feasibility and reliability of a continuous glucose monitoring system in a population of very low birth weight neonates needing parenteral nutrition. Moreover, we presented percentiles of glycemia of the studied population. METHODS: Very low birth weight neonates were enrolled within 24 h from birth. An ENLITE sensor connected to a continuous glucose monitoring system was inserted and maintained for at least 72 h. Data obtained with the continuous glucose monitoring system and with a glucometer were compared. Calibration was performed every 12 h. RESULTS: Twenty-three patients (9 males) were included. Median gestational age was 28 weeks (range 23-30) and median birth weight was 860 g (range 500-1092). A total of 299 paired glucose values were obtained. Modified Clarke Error Grid criteria for clinical significance were met. 74 and 33 episodes of hypoglycemia and hyperglycemia were detected, respectively. 31,329 values of glycemia were analyzed and the percentiles calculated. CONCLUSIONS: This continuous glucose monitoring system is safe and accurate. It allows increasing the detection of hypo- and hyper-glycaemia episodes and it could be routinely used in the management of glucose infusion in very low birth weight neonates under total parenteral nutrition.

Lung ultrasonography score versus chest X-ray score to predict surfactant administration in newborns with respiratory distress syndrome.

OBJECTIVES: We aim to verify the diagnostic accuracy of a lung ultrasonography (LUS) score to early predict the need for surfactant therapy in newborns with respiratory distress syndrome (RDS), and to compare it with a chest X-ray score. METHODS: In this prospective diagnostic accuracy study we included all newborns admitted for respiratory distress and initially treated with nasal CPAP. LUS was performed within 2 h from nasal CPAP positioning and in any case before surfactant administration. A chest X-ray was also performed. A LUS score and an X-ray score were used and compared. Ability of the scores to predict surfactant administration was evaluated through ROC analysis. RESULTS: In our population of 56 newborns with mean gestational age of 31 weeks (SD 3) and mean birth weight of 1442 g (SD 520), LUS score showed higher AUC than X-ray score in early recognition of infants with respiratory distress syndrome requiring surfactant treatment (0.94; 95%CI, 0.89-0.98; P < 0.001 vs 0.80; 95%CI, 0.74-0.86; P < 0.001). It showed also higher sensitivity (86% vs 82%), higher specificity (88% vs 76%), better positive (83% vs 69%), and negative (91% vs 87%) predictive values. CONCLUSIONS: LUS is a non-invasive, bedside and reproducible method that could improve the management of neonatal respiratory distress. It is accurate and reliable to early identify patients who will need treatment with surfactant allowing both an early treatment and a reduction of radiation exposure.

Using BiliCheck for preterm neonates in a sub-intensive unit: diagnostic usefulness and suitability.

BACKGROUND: BiliCheck (BC), a new transcutaneous bilirubinometer is thought to be lacking in the disadvantages of old devices and could be potentially useful for diagnosing jaundice in preterm babies. Although its accuracy is well known in healthy term babies, there is a lack of knowledge about its usefulness in preterm infants. AIMS: To investigate BC usefulness in preterm babies and its suitability in a sub-intensive neonatal unit. STUDY DESIGN: In 340 preterm infants between 30 and 36 weeks of gestational age, transcutaneous and serum bilirubin measurement were performed. Hematocrit, pH, postnatal age, gestational age, and sex were also studied to clarify their influence on BC accuracy. For a subset of 100 neonates transcutaneous measurement, blood collection and serum analysis were timed and costs were considered. RESULTS: Correlation coefficient is 0.795 (p<0.001) and this is not affected by factors previously supposed to be important. Overall sensitivity was 100% and specificity were comprised between 40% and 72%. BC has a tendency to overestimate serum bilirubin, at high values. Considering the whole time for serum bilirubin measurement, transcutaneous bilirubinometry is a faster (p<0.0001), but more expensive technique with a cost of about 5 euro/measurement. Nevertheless, using BC as a screening-device we could safely avoid 58-79% of blood samples, since its positive predictive values is about 21-42%. This would allow to a cost reduction of 1555-2120 euro/year. CONCLUSIONS: BC has a good reliability in preterm infants although not as good as in healthy term babies. BC is a time-sparing tool and can improve the management of neonatal jaundice in preterm infants; however, its tendency to overestimate suggests its use only for screening purposes.

Efficacy of a single dose of antenatal corticosteroids on morbidity and mortality of preterm infants.

OBJECTIVE: To assess the effectiveness of an incomplete course of antenatal corticosteroids (ACS) on neonatal morbidity and mortality of preterm infants. METHODS: Preterm infants born at 25-34 weeks' gestational age between January 1, 1998 and December 31, 2003 were included in this study. Studied infants were divided in two groups: the ACS group included those infants who had been exposed to a single 12-mg dose of betamethasone before delivery while the control group included those infants who had been delivered without any antenatal corticosteroids treatment. The most important neonatal outcomes were compared between the two groups. RESULTS: One hundred and seventy neonates (41.4%) were exposed to one 12-mg dose of betamethasone before delivery, while 241 neonates (58.6%) did not receive any antenatal corticosteroids treatment. Mean gestational age at delivery (30.4+/-2.4 weeks versus 31.2+/-2.9 weeks, p=0.004) and mean birth weight (1375+/-454 g versus 1625+/-580 g, p<0.001) were lower in the ACS group. The univariate analysis showed that delivery room intubation and respiratory distress syndrome were more frequent in the ACS group and that the length of stay was also significantly longer in this group. No differences were found concerning survival, neonatal morbidity, need for and duration of mechanical ventilation and oxygen therapy. The incidence of major outcomes in survivors was also similar. Logistic regression adjusted for gestational age showed that the exposure to a single dose of betamethasone before delivery was not associated with a significant reduction in the rate of any neonatal outcome. We also compared the outcomes in function of gestational age subclasses. In the 25-27 weeks subgroup, delivery room intubation, surfactant treatment and patent ductus arteriosus (PDA) were less frequent in ACS infants; they had also shorter ventilation and oxygen duration. In the 30-31 weeks subgroup, ACS infants had a lower incidence of mechanical ventilation and a shorter duration of oxygen therapy. Finally, no differences were found in the 28-29 weeks subgroup and in the 32-34 weeks subgroup. CONCLUSION: Effects of incomplete antenatal corticosteroids are variable: they give some benefits to infants of 25-27 weeks gestational age, fail to show any difference in outcomes in the 32-34 weeks subgroup and are doubtful between these extremes.

Neonatal color Doppler US study: normal values of cerebral blood flow velocities in preterm infants in the first month of life.

The aim of this study is to generate normal reference values of cerebral blood flow velocities (CBFV) and Doppler indices (DI) in the anterior (ACA) and the middle (MCA) cerebral arteries during the first month of life in "healthy" preterm infants. CBFV were obtained with color Doppler technique in seventy selected preterm infants divided in four groups of gestational age (GA) (25 to 28; 29 to 30; 31 to 32; 33 to 35 wk). Our data demonstrate that CBFV increase with rising GA, birth weight (BW) and postnatal age. Additionally, we can provide the median values, tenth and ninetieth percentiles of CBFV and DI, in the ACA and MCA in each GA group as reference normal values of CBFV and DI in preterm newborn.

Delivery room strategies and outcomes in preterm infants with gestational age 24-28 weeks.

OBJECTIVE: To investigate the effect of different delivery room strategies on survival, short term morbidity, and outcomes in extremely premature infants. METHODS: This retrospective cohort study included all preterm infants with a gestational age between 24 and 28 weeks who were born in 1992-1997 (period A; n = 161) and in 1998-2003 (period B; n = 163). In period A, elective intubation was performed. In period B, if spontaneous breathing was present, nasal continuous positive airway pressure (nCPAP) was applied. RESULTS: Survival rate and the number of never-intubated infants significantly increased in period B. No differences were found concerning short-term morbidity. Among major outcomes, the need for retinopathy of prematurity (ROP) surgery and the length of stay were significantly lower in period B. Subgroup analysis showed no significant differences from period A to period B in infants with gestational age 24-26 weeks. In the 27-28 weeks subgroup, the never-intubated infants rate increased from 2.8% to 21.3% and survival rate increased from 63% to 79%. A reduced need for ROP surgery and a shorter hospital stay were also observed. CONCLUSIONS: Changes in delivery room strategy tending to reduce mechanical ventilation in extremely premature infants are likely to benefit essentially infants of 27-28 weeks of gestation. Extension of such benefits to premature infants at the limit of viability requires further research.

Continuous glucose monitoring in preterm infants: evaluation by a modified Clarke error grid.

BACKGROUND: Continuous glucose monitoring using subcutaneous sensors has been validated in adults and children with diabetes, and was found to be useful in the management of glucose control. We aimed to assess feasibility and reliability of a new continuous glucose monitoring system (CGMS) in a population of preterm neonates using a Clarke error grid (CEG) specifically modified for preterm infants. METHODS: Preterm infants were recruited within 24 h from delivery. A subcutaneous sensor connected to a CGMS was inserted and maintained for 6 days. Data collected from CGMS were compared with data obtained using a glucometer. Management of the infants followed standard protocols and was not influenced by CGMS readings. RESULTS: Twenty patients (9 males) were included. Median (range) gestational age was 32 weeks (27-36) and median (range) birth weight was 1350 g (860-3360). Average CGMS recording time was 137 h, for a total of 449 paired glucose levels. CEG and modified CEG criteria for clinical significance were met. CONCLUSION: CGMS is a safe and clinically adequate method to estimate glucose levels in preterm infants. As the glucose level can be evaluated in real time, this CGMS could be useful to reduce the number of heel sticks, to observe glycaemic trends and to promptly detect episodes of both hypo- and hyper-glycaemia.
