BACKGROUND: Several small randomized controlled trials (RCTs) and observational studies have compared high (15-20/7.5-10/7.5-10 mg/kg/dose) versus standard dose (10/5/5 mg/kg/dose) ibuprofen for patent ductus arteriosus (PDA) closure, with limited evidence on efficacy and safety. OBJECTIVE: To systematically review and meta-analyze studies of high versus standard dose ibuprofen for the closure of PDA in preterm infants. METHODS: Databases were searched for RCTs and observational studies assessing high compared to standard dose of ibuprofen for PDA closure for preterm infants until August 2021. The primary outcome was failure of PDA closure after the first course of ibuprofen. The secondary outcomes were the failure of PDA closure after a second course of ibuprofen, rates of PDA ligation, all-cause mortality prior to hospital discharge, bronchopulmonary dysplasia, necrotizing enterocolitis, bleeding disorders, oliguria, and serum creatinine after treatment. RESULTS: There were 6 studies with 369 patients (3 RCT, N = 190; 3 observational studies, N = 179). Compared to standard dose, high dose ibuprofen did not significantly decrease the failure rate of PDA closure in preterm infants after the first course (Relative risk (RR) 0.74, 95% confidence interval (CI) 0.53 –1.03, 6 studies, N = 369). High dose ibuprofen significantly decreased the rates of PDA ligation compared to standard dose (RR 0.33, 95% CI 0.16 –0.70, 5 studies, N = 309). INTERPRETATION: Based on low-grade evidence, high dose ibuprofen may more effectively reduce rates of PDA ligation compared to standard dose with no increase in adverse effects, neonatal morbidities and mortality.

Background: Necrotising enterocolitis (NEC) in preterm infants is associated with high morbidity and mortality. In most neonates, it is a progressive disease from medical NEC (mNEC) to surgical NEC (sNEC); however, in some, it presents as sNEC from onset., Objective: To evaluate the rate, the timing of progression, different surgical approaches, and outcomes of mNEC and sNEC in preterm neonates., Design: A retrospective cohort study of preterm infants with diagnosis of NEC between 2010 and 2020 was conducted. Data on clinical presentation, NEC progression, treatment received, different surgical approaches, resource utilization, and outcomes were abstracted. Infants were classified into 3 groups: mNEC, mNEC that progressed to sNEC, and sNEC at presentation., Results: Among 208 included infants with NEC, 109 (52%) were mNEC, 66 (32%) progressed from mNEC to sNEC, and 33 (16%) presented with sNEC. Gestational age, birth weight, and postnatal age at NEC were inversely associated with the development of sNEC. mNEC progressed to sNEC occurred after a median of 2.5 (IQR 1-4.25) days. Ninety (91%) of sNEC patients underwent interventions: peritoneal drain only in 19 (21%), laparotomy in 59 (66%), or both in 12 (13%). In comparison with mNEC, those with sNEC infants had longer duration on antibiotics, inotropes, respiratory support, length of stay, and time to reaching full enteral feeds; and were more likely to have recurrent NEC episodes, BPD, and mortality., Conclusion: There is a high burden of illness for sNEC cases. Insight into the expected clinical course of sNEC patients can facilitate anticipatory management and provide a window of opportunity for timely interventions that may ameliorate the course of sNEC., Competing Interests: Declarations.

Purpose: The STAT trial is a multicenter randomized controlled trial in 12 centers worldwide aiming to determine the most effective operation for neonates with necrotizing enterocolitis (NEC) requiring intestinal resection: stoma formation (ST) or primary anastomosis (PA)., Methods: Infants having a primary laparotomy for NEC were randomized intraoperatively to PA or ST if the operating surgeon thought that both were viable treatment options for that patient. The primary outcome (duration of parenteral nutrition [PN]) was evaluated by Cox regression., Results: Eighty patients were recruited from 2010 to 2019. Infants undergoing anastomosis finished PN significantly earlier than patients undergoing stoma (hazard ratio PA vs. ST 2.38, 95% CI 1.36-4.12 p = 0.004). There was no difference in mortality between the two groups (PA 4/35 vs. ST 8/38 p = 0.35) or in the rate of complications requiring further unplanned operations (p = n.s.). Multiple intestinal complications were more frequent in the stoma group compared to the anastomosis group (ST 12/26 vs. PA 5/31, p = 0.02, Fisher's Exact test)., Conclusion: At laparotomy for NEC, when there is no disease distal to resected intestine, primary anastomosis should be performed as it enhances the recovery from NEC, reduces the risk of multiple intestinal complications and does not increase adverse outcomes., (© 2024.

Background: Preterm infants born at <32 weeks gestational age (GA) have increased morbidity if they are born outside tertiary centres (outborn). Stabilization and resuscitation after birth consistent with the neonatal Golden Hour practices (NGHP) are required to optimize outcomes., Objectives: To evaluate physiological outcomes of hypothermia and hypoglycaemia, and compliance with NGHP by neonatal transport team (NTT) compared with referral hospital team (RHT) during the stabilization of infants born at <32 weeks GA., Methods: A retrospective case-control study of infants born at <32 weeks GA during 2016-2019 at non-tertiary perinatal centres where the NTT attended the delivery (cases) were matched to infants where the RHT team attended the delivery (controls)., Results: During the 4-year period, NTT team received 437 requests to attend deliveries at <32 weeks GA and attended 76 (17%) prior to delivery. These cases were matched 1:1 with controls composed of deliveries attended by the RHT. The rate of hypothermia was 15% versus 29% in the NTT and RHT groups, respectively (P = 0.01). The rate of hypoglycaemia (<2.2 mmol/L) was 5% versus 12% in the NTT and RHT groups, respectively (P = 0.64). For compliance with the NGHP, use of fluid boluses was 8% versus 33%, use of thermoregulation practices, that is, plastic bag, was 76% versus 21%, and establishment of intravenous access was 20 min versus 47 min, in the NTT and RHT groups, respectively., Conclusions: High-risk preterm deliveries attended by the NTT compared with the RHT had increased compliance and earlier implementation of the NGHP elements, associated with improved physiological stability and lower hypothermia rates. Outreach education for RHT should ensure that these key elements are included during the training in the stabilization of high-risk preterm deliveries., Competing Interests: All authors reported that there are no conflicts of interest.

Objective: This study aimed to determine the incidence of umbilical venous catheter associated infection (UVCAI) in very preterm infants based on UVC tip position., Study Design: In this retrospective cohort study, infants born at ≤32 weeks were divided into groups with a UVC tip in either a low-lying or good position. The primary outcome was UVCAI. Survival analysis represented time to infection between groups. Subgroup analyses were based on duration of UVC indwelling time., Results: Of 1,983 infants, 1,638 infants were eligible; 33% had low-lying UVC and 67% had good position UVC. Survival analyses suggested a significantly higher probability of infection was associated with low UVC (adjusted hazard ratio [HR]: 1.9, 95% confidence interval [CI]: 1.1-3.2; p  = 0.001). The risk of infection was higher for UVC of >7 days duration (adjusted HR: 2.2, 95% CI: 1.1-4.2). Extravasation as a complication was significantly higher in the low UVC versus good position UVC (1.3 vs. 0.1%; odds ratio: 14.4, 95% CI: 1.8-119)., Conclusion: Low-lying UVC was associated with higher risk of infection and extravasation., Key Points: · Low-lying UVC are at higher risk of UVCAI.. · Presence of UVC in situ for > 7 days carries higher risk of UVCAI.. · There was a higher risk of UVC extravasation with low UVCs.., Competing Interests: None declared., (Thieme.

Introduction: The availability of and variability in healthcare professionals in neonatal units in different countries has not been well characterized. Our objective was to identify variations in the healthcare professionals for preterm neonates in 10 national or regional neonatal networks participating in the International Network for Evaluating Outcomes (iNeo) of neonates., Method: Online, pre-piloted questionnaires about the availability of healthcare professionals were sent to the directors of 390 tertiary neonatal units in 10 international networks: Australia/New Zealand, Canada, Finland, Illinois, Israel, Japan, Spain, Sweden, Switzerland, and Tuscany., Results: Overall, 325 of 390 units (83%) responded. About half of the units (48%; 156/325) cared for 11-30 neonates/day and had team-based (43%; 138/325) care models. Neonatologists were present 24 h a day in 59% of the units (191/325), junior doctors in 60% (194/325), and nurse practitioners in 36% (116/325). A nurse-to-patient ratio of 1:1 for infants who are unstable and require complex care was used in 52% of the units (170/325), whereas a ratio of 1:1 or 1:2 for neonates requiring multisystem support was available in 59% (192/325) of the units. Availability of a respiratory therapist (15%, 49/325), pharmacist (40%, 130/325), dietitian (34%, 112/325), social worker (81%, 263/325), lactation consultant (45%, 146/325), parent buddy (6%, 19/325), or parents' resource personnel (11%, 34/325) were widely variable between units., Conclusions: We identified variability in the availability and organization of the healthcare professionals between and within countries for the care of extremely preterm neonates. Further research is needed to associate healthcare workers' availability and outcomes., (© 2019 S. Karger AG, Basel.)
