Jung JK, Kim EY, Heo JS, Park KH, Choi BM. Analysis of perinatal risk factors for massive pulmonary hemorrhage in very low birth weight infant: A nationwide large cohort database. Early Hum Dev 2024; 191:105977. [PMID: 38460343 DOI: 10.1016/j.earlhumdev.2024.105977] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2023] [Revised: 02/28/2024] [Accepted: 02/28/2024] [Indexed: 03/11/2024]
Abstract
OBJECTIVE To determine perinatal risk factors for Massive pulmonary hemorrhage (MPH) and MPH-caused mortality to guide clinicians in implementing preventive measures at the beginning of life for improving the survival of very low birth weight infant (VLBWIs). STUDY DESIGN A total of 13,826 VLBWIs born between 2013 and 2020 in the Korean Neonatal Network database were included. RESULTS MPH occurred in 870 (6.3 %) VLBWIs. Among infants with MPH, 162 (18.6 %) VLBWIs died due to MPH. In the multivariate logistic regression analysis, independent risk factors for MPH were identified as small for gestational age, multiple gestation, high CRIB-II score, use of surfactant, and symptomatic patent ductus arteriosus (sPDA) in VLBIWs. Independent risk factors for MPH-caused mortality were identified as multiple gestation in VLBWIs. Receiving a complete course of antenatal corticosteroids (ACS) was found to be a significant independent protective factor for MPH-caused mortality in VLBWIs. CONCLUSION Proactive managements for reducing unnecessary use of pulmonary surfactant and for decreasing the risk of sPDA at the beginning of life could be recommended as preventive strategies to reduce the risk of MPH in extremely preterm infants. ACS therapy is highly recommended for women with a high likelihood of giving birth preterm to reduce the risk of mortality caused by MPH.

Abstract
OBJECTIVES Pulmonary hemorrhage (PH) is one kind of critical lung diseases in newborn infants, which is the most difficult one to be diagnosed by ultrasound. This study was to investigate the specific ultrasonic signs of PH in order to better diagnose neonatal PH by using lung ultrasound (LUS). METHODS A total 168 newborn infants were enrolled in this study, which included PH, pneumonia, meconium aspiration syndrome, and newborns without lung diseases, there were 42 cases in each group. In a quiet state, infants were placed in the supine, lateral or prone position for the examination. Each lung was divided into the anterior, lateral and posterior regions, then each region of both lungs was scanned with the probe perpendicular to the ribs or parallel to the Intercostal spaces. RESULTS The major results showed that: (1) the common LUS manifestation of PH includes lung consolidation, air bronchograms, fluid bronchograms, pleural effusion, shred signs, pleural line abnormality and B-lines, while fibrin deposition sign is a rare sign of PH. (2) Co-existing of lung consolidation with fluid bronchograms and pleural effusion is the specific sign of PH with a sensitivity of 81.0%, specificity of 98.4% and the positive predictive value (PPV) was 94.4%. (3) Fibrin deposition sign is an uncommon specific LUS sign of PH with a sensitivity 28.6%, specificity of 100% and the PPV was 100%. (4) Nine patients (21.4%) were diagnosed with PH based on ultrasound findings before oronasal bleeding. (5) The survival rate of infants with PH was 100% in this study. CONCLUSION LUS is helpful for the early diagnosis of neonatal PH and may therefore improve the prognosis. The lung consolidation with fluid bronchograms and pleural effusion as well as fibrin deposition sign are specific to diagnose PH by using LUS.

Abstract
Pulmonary hemorrhage (PH) is a rare acute catastrophic event with high mortality among neonates, especially preterm infants. Primary treatments included pulmonary surfactant, high-frequency oscillatory ventilation, epinephrine, coagulopathy management, and intermittent positive pressure ventilation. However, there are still challenges in diagnosing and treating refractory or focal pulmonary hemorrhages. Ultra-slim bronchoscopy has been widely used in the field of critically ill children and is increasingly being done in neonates with critical respiratory disease in recent years. In this study, we report a case with refractory pulmonary hemorrhage in premature infants, which was finally diagnosed as localized hemorrhage in the upper left lobe and cured by ultra-slim bronchoscopy-guided topical hemostatic drug administration. Bronchoscopy is an optional, safe, and practicable technique for early diagnosis and direct injection therapy of neonatal PH in managing life-threatening PH.

Abstract
BACKGROUND Pulmonary hemorrhage is a potentially fatal event especially for preterm infants, which can lead to serious complications and even death. Many risk factors have been associated with the development of massive pulmonary hemorrhage. However, there is still no effective strategy to prevent massive pulmonary hemorrhage. The purpose of this study is to explore prediction model and survival strategies for massive pulmonary hemorrhage in premature infants. METHODS In this retrospective study, we included all premature infants with birth weight <1,500 g who were hospitalized in our neonatal intensive care unit (NICU) between January 01 2010 and December 31 2019. RESULTS Of 599 preterm infants, 51 developed massive pulmonary hemorrhage. The logistic regression analysis showed that patent ductus arteriosus [odds ratio (OR) =11.4, 95% confidence interval (CI): 4.79-27.0, P<0.0001], coagulopathy (OR =6.56, 95% CI: 2.83-15.2, P<0.0001), and 10-minute Apgar Score (OR =0.52, 95% CI: 0.37-0.73, P=0.0001) were risk factors for massive pulmonary hemorrhage. Whether or not surfactant is used, the positive predictive value of combined patent ductus arteriosus and coagulopathy for predicting massive pulmonary hemorrhage was 68.9% and 70.4%, respectively. Of the 51 preterm infants with massive pulmonary hemorrhage, 25 died and 26 survived. The survivors group had higher positive end-expiratory pressure compared with the deceased group after the onset of massive pulmonary hemorrhage. After adjusting for potential risk factors, the multiple logistic regression analysis showed that higher positive end-expiratory pressure levels are closely related to survival. CONCLUSIONS Patent ductus arteriosus combined with coagulopathy has a high predictive value for massive pulmonary hemorrhage. Higher positive end-expiratory pressure levels may reduce mortality in massive pulmonary hemorrhage.

Abstract
BACKGROUND Pulmonary hemorrhage (PH) is a life-threatening respiratory complication of extremely low-birth-weight infants (ELBWIs). However, the risk factors for PH are controversial. Therefore, the purpose of this study was to analyze the perinatal risk factors and short-term outcomes of PH in ELBWIs. METHODS This was a retrospective cohort study of live born infants who had birth weights that were less than 1000 g, lived for at least 12 hours, and did not have major congenital anomalies. A logistic regression model was established to analyze the risk factors associated with PH. RESULTS There were 168 ELBWIs born during this period. A total of 160 infants were included, and 30 infants were diagnosed with PH. Risk factors including gestational age, small for gestational age, intubation in the delivery room, surfactant in the delivery room, repeated use of surfactant, higher FiO2 during the first day, invasive ventilation during the first day and early onset sepsis (EOS) were associated with the occurrence of PH by univariate analysis. In the logistic regression model, EOS was found to be an independent risk factor for PH. The mortality and intraventricular hemorrhage rate of the group of ELBWIs with PH were significantly higher than those of the group of ELBWIs without PH. The rates of periventricular leukomalacia, moderate-to-severe bronchopulmonary dysplasia and severe retinopathy of prematurity, and the duration of the hospital stay were not significantly different between the PH and no-PH groups. CONCLUSIONS Although PH did not extend hospital stay or increase the risk of bronchopulmonary dysplasia, it increased the mortality and intraventricular hemorrhage rate in ELBWIs. EOS was the independent risk factor for PH in ELBWIs.

Impaired platelet activity and hypercoagulation in healthy term and moderately preterm newborns during the early neonatal period. Pediatr Res 2019; 85:63-71. [PMID: 30283046 DOI: 10.1038/s41390-018-0184-8] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2018] [Revised: 08/29/2018] [Accepted: 09/04/2018] [Indexed: 12/26/2022]
Abstract
BACKGROUND Preterm newborns are at thrombohemorrhagic risk during the early neonatal period. Taking into account the lack of informative tools for the laboratory diagnosis of hemostasis disorders in newborns, our goal was to determine the baseline values of thrombodynamics and platelet functional activity in healthy term and moderately preterm newborns during the early neonatal period future potential clinical use of these tests. METHODS Coagulation was assessed using an integral assay of thrombodynamics and standard coagulation assays, and platelet functional activity was estimated by flow cytometry. RESULTS Hypercoagulation of newborns, represented by a significantly higher clot growth velocity and the presence of spontaneous clots in the thrombodynamics, was combined with platelet hypoactivity. Granule release, phosphatidylserine exposure, and the ability to change shape upon activation were decreased in the platelets of moderately preterm newborns. The platelet function remained at the same level over the first four days of life, whereas the hypercoagulation became less pronounced. CONCLUSIONS The hemostasis of newborns is characterized by hypercoagulation combined with reduced platelet functional activity. Moderately preterm and term newborns do not differ in the parameters of coagulation, while some of the functional responses of platelets are lower in moderately preterm newborns than in term.

Abstract
OBJECTIVE To investigate the risk factors for neonatal pulmonary hemorrhage (NPH) in the neonatal intensive care unit (NICU) of a municipal hospital, and to provide a basis for the early identification and treatment of NPH. METHODS A total of 112 neonates who were admitted to the NICU of Shaoyang Central Hospital of Hunan Province and diagnosed with NPH were enrolled as the case group. A nested case-control method was used to select, as a control group (n=224), the neonates who underwent the treatment with an assisted mechanical ventilator and did not experience pulmonary hemorrhage. Univariate analysis and unconditional logistic regression analysis were used to identify the high risk factors for NPH. RESULTS The univariate analysis showed that compared with the control group, the case group had significantly higher incidence rates of gestational diabetes and cholestasis in mothers, cesarean delivery, gestational age <34 weeks, 5-minute Apgar score ≤5, birth weight <2 500 g, heart failure and disseminated intravascular coagulation (DIC) before the development of NPH, partial pressure of oxygen/fraction of inspired oxygen (oxygenation index, OI) ≤100, and a reduction in mean platelet volume. The multivariate logistic regression analysis showed that DIC, heart failure, and OI ≤100 were independent risk factors for NPH (OR=33.975, 3.975, 1.818 respectively; P<0.05). CONCLUSIONS Heart failure, OI ≤100, and DIC are risk factors for the development of NPH in the NICU of the municipal hospital.
