    Effect of two different chest compression techniques on ventilation during neonatal resuscitation
    (2021) Jahnsen, Johanne; Gonzalez, Alvaro; Fabres, Jorge; Bahamondes, Alejandra; Estay, Alberto
    Objective To assess tidal volume (Vt) and minute ventilation (MV) during cardiopulmonary resuscitation (CPR) with two different chest compressions techniques: two-finger (TFT) or two-thumb technique (TTT) in a neonatal model. Methods Vt and MV were continuously measured during consecutive periods of resuscitation in an intubated manikin. Thirty participants performed the two compression techniques in a random order for 2-min periods while performing positive pressure ventilation using a T-piece resuscitator (TPR) or a self-inflating bag (SIB). Results Vt during CPR with TFT was significantly higher than TTT with either TPR: 44.9 +/- 4.3 vs 39.2 +/- 5.4 ml (p < 0.001) or SIB: 39.2 +/- 5.7 vs 35.6 +/- 6.5 ml (p < 0.023). Similarly MV was significantly higher in TFT than TTT with either mode: 1346 +/- 130 vs 1175 +/- 162 ml/min, respectively, with TPR (p < 0.001) and 1177 +/- 170 vs 1069 +/- 196 ml/min with SIB (p < 0.03). Conclusions Chest compressions during CPR using the TFT achieved higher Vt and MV than TTT in this model of neonatal resuscitation.

    Enteral Feeding and Necrotizing Enterocolitis: Does Time of First Feeds and Rate of Advancement Matter?
    (LIPPINCOTT WILLIAMS & WILKINS, 2021) Masoli, Daniela; Domínguez De Landa, María Angélica; Tapia, Jose L.; Uauy, Ricardo; Fabres, Jorge; NEOCOSUR Collaborative Network
    The aim of the study was to determine if time to initial enteral feeding (EF) and rate of advancement are associated with necrotizing enterocolitis (NEC) or death. Methods: Secondary analysis of prospectively collected data of very-low-birth-weight infants (VLBWI: 400--1500 g) born in 26 NEOCOSUR centers between 2000 and 2014. Results: Among 12,387 VLBWI, 83.7% survived without NEC, 6.6% developed NEC and survived, and 9.6% had NEC and died or died without NEC (NEC/death). After risk adjustment, time to initial EF (median = 2 days) was not associated with NEC; however, delaying it was protective for NEC/death (odds ratio [OR] = 0.96; 95% confidence interval [CI] 0.93--0.99). A slower feeding advancement rate (FAR) was protective for NEC (OR = 0.97; 95% CI = 0.94-0.98) and for NEC/death (OR = 0.98; 95% CI = 0.96-0.99). Conclusions: In VLBWI, there was no association between an early initial EF and NEC, although delaying it was associated with less NEC/death. A slower FAR was associated with lower risk of both outcomes.

    Improvement of survival in infants with congenital diaphragmatic hernia in recent years: effect of ECMO availability and associated factors
    (2010) Kattan, Javier; Godoy, Loreto; Zavala, Alejandro; Faunes, Miriam; Becker, Pedro; Estay, Alberto; Fabres, Jorge; Toso, Paulina; Urzua, Soledad; Becker, Jorge; Cerda, Jaime; Gonzalez, Alvaro
    Survival of patients with congenital diaphragmatic hernia (CDH) depends both on non-modifiable congenital conditions and on modifiable pre and postnatal management. ECMO improves survival up to 80% in neonates with CDH in the best ECMO centers worldwide. The first Neonatal ECMO Program in Chile was started in our University in 2003. Our objective is to determine the impact of a Neonatal ECMO Program in a level III NICU on newborns with CDH.

    OBJECTIVE: To determine whether CS delivery and receipt of antenatal steroids (ANS) in vertex-presenting singletons with a gestational age (GA) between 24 and 30 weeks is associated with improved survival and improved severe intraventricular hemorrhage (sIVH)-free survival.

    Randomized Trial of Early Bubble Continuous Positive Airway Pressure for Very Low Birth Weight Infants
    (MOSBY-ELSEVIER, 2012) Tapia, Jose L.; Urzua, Soledad; Bancalari, Aldo; Meritano, Javier; Torres, Gabriela; Fabres, Jorge; Toro, Claudia A.; Rivera, Fabiola; Cespedes, Elizabeth; Burgos, Jaime F.; Mariani, Gonzalo; Roldan, Liliana; Silvera, Fernando; Gonzalez, Agustina; Dominguez, Angelica; S Amer Neocosur Network
    Objective To determine whether very low birth weight infants (VLBWIs), initially supported with continuous positive airway pressure (CPAP) and then selectively treated with the INSURE (intubation, surfactant, and extubation to CPAP; CPAP/INSURE) protocol, need less mechanical ventilation than those supported with supplemental oxygen, surfactant, and mechanical ventilation if required (Oxygen/mechanical ventilation [MV]).

    Results of Extremely-low-birth-weight Infants Randomized to Receive Extra Enteral Calcium Supply
    (LIPPINCOTT WILLIAMS & WILKINS, 2011) Carroll, William F.; Fabres, Jorge; Nagy, Tim R.; Frazier, Marcela; Roane, Claire; Pohlandt, Frank; Carlo, Waldemar A.; Thome, Ulrich H.
    Background and Objective: Bone mineral deficiency continues to occur in extremely-low-birth-weight (ELBW) infants despite formulas enriched in calcium (Ca) and phosphorus (P). This study tested whether extra enteral Ca supplementation increases bone mineral content (BMC) and prevents dolichocephalic head flattening and myopia in ELBW infants.

    Self-directed video versus instructor-based neonatal resuscitation training: a randomized controlled blinded non-inferiority multicenter international study
    (2021) Szyld, Edgardo G.; Aguilar, Adriana; Lloret, Santiago Perez; Pardo, Amorina; Fabres, Jorge; Castro, Adriana; Dannaway, Douglas; Desai, Purnahamsi V.; Capelli, Carola; Song, Clara H.; Enriquez, Diego; Szyld, Demian
    Objective To compare the efficacy of video-assisted self-directed neonatal resuscitation skills course with video-assisted facilitator-led course. Methods This multicenter, randomized, blinded, non-inferiority-controlled trial compared two methods of teaching basic neonatal resuscitation skills using mask ventilation. Groups of novice providers watched an instructional video. One group received instructor facilitation (Ins-Video). The other group did not (Self-Video). An Objective Structured Clinical Exam (OSCE) measured skills performance, and a written test gauged knowledge. Results One hundred and thirty-four students completed the study. Sixty-three of 68 in the Self-Video Group (92.6%) and 59 of 66 in the Ins-Video Group (89.4%) achieved post-training competency in positive pressure ventilation (primary outcome). OSCE passing rates were low in both groups. Knowledge survey scores were comparable between groups and non-inferior. Conclusions Video self-instruction taught novice providers positive pressure ventilation skills and theoretical knowledge, but it was insufficient for mastery of basic neonatal resuscitation in simulation environment.
