Zespół stresu oddechowego noworodka
Diagnostyka i diagnoza

Zespół stresu oddechowego noworodka (ZSON) jest najczęstszym zaburzeniem oddechowym u wcześniaków, charakteryzującym się objawami niewydolności oddechowej pojawiającymi się w ciągu pierwszych 6 godzin życia, z progresją w ciągu 48-72 godzin. Diagnostyka opiera się na ocenie klinicznej (tachypnoe >60/min, wciąganie międzyżebrzy, sinica centralna), badaniach obrazowych oraz gazometrii krwi tętniczej wykazującej hipoksemię, hiperkapnię i kwasicę oddechową lub mieszana. Radiografia klatki piersiowej pozostaje złotym standardem, ukazując obraz „mlecznego szkła”, bronchogramy powietrzne i zmniejszoną objętość płuc, z 90% pewnością rozpoznania. Ultrasonografia płuc (LUS) wykazuje wysoką czułość (92%, 95% CI: 0,89-0,94) i swoistość (95%, 95% CI: 0,93-0,97), a obecność konsolidacji, nieprawidłowości linii opłucnowej i zaniku linii A daje czułość i swoistość 100%. Pulsoksymetria i test stabilnych mikropęcherzyków (SMT) stanowią dodatkowe narzędzia diagnostyczne, a echokardiografia służy do wykluczenia patologii sercowych, takich jak przetrwały przewód tętniczy (PDA).

Diagnostyka zespołu stresu oddechowego noworodka

Zespół stresu oddechowego noworodka (ZSON), znany również jako choroba błon szklistych, stanowi jedno z najczęstszych zaburzeń oddechowych występujących u noworodków, szczególnie u wcześniaków. Jest główną przyczyną zwiększonej zachorowalności i śmiertelności u noworodków urodzonych przedwcześnie, których płuca nie są w pełni rozwinięte.12 Wczesna i precyzyjna diagnostyka tego schorzenia jest kluczowa dla wdrożenia odpowiedniego leczenia i poprawy rokowania.

Objawy kliniczne i badanie fizykalne

Diagnoza ZSON opiera się przede wszystkim na połączeniu oceny klinicznej, wywiadu prenatalnego i wyników badań diagnostycznych. Noworodek z zespołem stresu oddechowego zwykle rodzi się przedwcześnie i prezentuje objawy niewydolności oddechowej bezpośrednio po porodzie lub w ciągu kilku minut od urodzenia.34

Charakterystyczne objawy kliniczne ZSON obejmują:56

  • Tachypnoe (przyspieszony oddech) – częstość oddechów przekracza 60/min
  • Wciąganie międzyżebrzy i mostka
  • Stękanie wydechowe
  • Wysiłek oddechowy i poszerzenie skrzydełek nosa
  • Sinica centralna

7

Naturalny przebieg choroby charakteryzuje się pojawieniem się objawów klinicznych w ciągu pierwszych 6 godzin życia, z postępującym pogorszeniem w ciągu pierwszych 48-72 godzin, a następnie stopniową poprawą.8 Noworodki z ZSON często wymagają zwiększonego wsparcia oddechowego i suplementacji tlenem.9

Badania obrazowe

Radiografia klatki piersiowej

Klasyczne badanie radiologiczne klatki piersiowej jest uważane za „złoty standard” w diagnostyce ZSON i wykazuje charakterystyczne cechy:1011

  • Jednorodne, nieprzejrzyste (matowe) zacienienia o wyglądzie „mlecznego szkła” (ang. ground-glass appearance)
  • Widoczne bronchogramy powietrzne (kontrastujące wypełnione powietrzem oskrzela na tle bezpowietrznej tkanki płucnej)
  • Zmniejszona objętość płuc
  • Ziarnisto-siateczkowa struktura płuc

1213

Obecność typowego obrazu radiologicznego pozwala postawić diagnozę ZSON z 90% pewnością.14 W ciężkich przypadkach zmiany mogą być na tyle nasilone, że granice serca stają się niewidoczne (obraz „białego płuca”). Prawidłowy obraz radiologiczny w 6. godzinie życia wyklucza rozpoznanie ZSON.15

Ultrasonografia płuc

W ostatnich latach ultrasonografia płuc (LUS) stała się cennym narzędziem diagnostycznym w rozpoznawaniu ZSON, oferując kilka istotnych zalet – jest to metoda nieinwazyjna, pozbawiona promieniowania jonizującego, przenośna i umożliwiająca szybką diagnostykę przy łóżku pacjenta.1617

Główne ultrasonograficzne kryteria diagnostyczne ZSON obejmują:1819

  • Obustronny obraz „białego płuca” (zespół pęcherzykowo-śródmiąższowy)
  • Nieprawidłowości linii opłucnowej
  • Konsolidacje płucne z bronchogramami powietrznymi
  • Zanik linii A
  • Objaw pulsu płucnego

Metaanaliza wykazała, że ultrasonografia płuc ma wysoką czułość (92%, 95% CI: 0,89-0,94) i swoistość (95%, 95% CI: 0,93-0,97) w diagnozowaniu ZSON.20 Jednoczesne występowanie konsolidacji płucnej, nieprawidłowości linii opłucnowej oraz obustronnego obrazu „białego płuca” lub konsolidacji płucnej, nieprawidłowości linii opłucnowej i zaniku linii A wykazuje czułość i swoistość wynoszącą 100% dla rozpoznania ZSON.21

Należy jednak pamiętać, że ultrasonografia płuc może potencjalnie nie wykryć odmy opłucnowej, odmy śródpiersia lub odmy osierdzia, dlatego klasyczna radiografia klatki piersiowej pozostaje niezbędna w przypadku podejrzenia tych powikłań.22

Echokardiografia

Echokardiografia (EKG) jest często wykonywana w celu wykluczenia problemów sercowych, które mogłyby powodować objawy podobne do ZSON. Jest to badanie ultrasonograficzne, które ocenia strukturę i funkcję serca oraz może wykazać, czy przetrwały przewód tętniczy (PDA) pogarsza stan kliniczny noworodka.232425

Badania laboratoryjne

Analiza gazometrii

Badanie gazometryczne krwi tętniczej stanowi kluczowy element diagnostyki ZSON, wykazując charakterystyczne zaburzenia:2627

  • Hipoksemia (obniżone ciśnienie parcjalne tlenu, pO₂), która reaguje na zwiększoną suplementację tlenem
  • Hiperkapnia (podwyższone ciśnienie parcjalne dwutlenku węgla, pCO₂)
  • Kwasica oddechowa lub mieszana kwasica oddechowo-metaboliczna

28

W miarę postępu choroby można zaobserwować narastającą kwasicę oddechową i metaboliczną, w tym mleczanową, u noworodków z pogarszającym się ZSON.29 Analiza badań gazometrycznych przed i po podaniu surfaktantu i wziewnych kortykosteroidów wykazała istotne statystycznie zmiany wartości parametrów takich jak FiO₂, pH, pCO₂, HCO₃ i BE (Sig. < 0,05).30

Pulsoksymetria

Pulsoksymetria jest nieinwazyjną metodą monitorowania saturacji tlenem (SpO₂) krwi za pomocą czujnika przymocowanego do palca, ucha lub palca u stopy noworodka. Jest to podstawowe narzędzie do oceny stopnia hipoksemii i monitorowania odpowiedzi na terapię tlenem.3132

Departament Zdrowia i Opieki Społecznej USA zaleca pulsoksymetrię zamiast samego badania fizykalnego do badań przesiewowych w kierunku krytycznych wrodzonych wad serca. Noworodki powinny być badane za pomocą pulsoksymetrii po 24 godzinach, ale przed wypisem ze szpitala.33

Test stabilnych mikropęcherzyków

Test stabilnych mikropęcherzyków (SMT) na aspiratach żołądkowych i płynie owodniowym jest wykorzystywany w diagnostyce ZSON. Badania wykazały, że test ten można również wykonać na aspiratach z jamy ustnej, co stanowi wiarygodną alternatywę dla badania płynu żołądkowego.34

Liczba mikropęcherzyków stabilnych w aspiratach z jamy ustnej wykazuje wysoką dokładność w diagnostyce ZSON, z czułością 81,4% i swoistością 85,7% dla punktu odcięcia 25 SMB/mm². Wartości te są podobne do tych uzyskanych w płynie żołądkowym dla punktu odcięcia 15 SMB/mm² (odpowiednio 95,4% i 61,9%).35

Badania dojrzałości płuc płodu

ZSON można przewidzieć prenatalnie za pomocą testów dojrzałości płuc płodu, które są wykonywane na płynie owodniowym uzyskanym przez amniopunkcję lub zebranym z pochwy (jeśli błony pękły).36

Testy te obejmują:37

  • Stosunek lecytyny do sfingomieliny (L/S) – stosunek L/S ≥ 2,0 wskazuje na dojrzałość płuc płodu i zmniejszone ryzyko ZSON
  • Test stabilności piany
  • Stosunek surfaktantu do albuminy

Opracowano również szybką metodę przyłóżkową przewidywania ZSON poprzez pomiar stosunku lecytyny do sfingomieliny (L/S) w aspiratach żołądkowych, opartą na spektroskopii w podczerwieni z transformacją Fouriera. Ta nowa metoda wykazała wysoką czułość w pomiarze stosunku L/S przy urodzeniu.38

Badania dodatkowe

Dodatkowe badania laboratoryjne mogą pomóc w wykluczeniu innych przyczyn zaburzeń oddechowych:39

  • Pełna morfologia krwi z rozmazem – stosunek niedojrzałych do całkowitej liczby neutrofilów > 0,2 sugeruje infekcję
  • Poziom białka C-reaktywnego < 10 mg/l (95,24 nmol/l) wyklucza sepsę z 94% negatywną wartością predykcyjną, gdy uzyskano je 24 i 48 godzin po urodzeniu

Diagnostyka różnicowa

ZSON należy różnicować z innymi stanami powodującymi zaburzenia oddechowe u noworodków, takimi jak:4041

  • Przejściowe tachypnoe noworodka (TTN) – charakteryzuje się szybkim oddechem i zatrzymaniem płynu w płucach; zwykle ustępuje w ciągu 24-72 godzin
  • Zespół aspiracji smółki (MAS) – związany z aspiracją płynu owodniowego zanieczyszczonego smółką
  • Zapalenie płuc u noworodków – powodowane przez zakażenie bakteryjne, wirusowe lub grzybicze
  • Wrodzona przepuklina przeponowa – defekt rozwojowy przepony pozwalający narządom jamy brzusznej przemieścić się do klatki piersiowej
  • Przetrwałe nadciśnienie płucne noworodków (PPHN) – charakteryzuje się wysokim oporem naczyń płucnych i prawym przełożeniem dopełnieniem przez otwór owalny i/lub przewód tętniczy

W różnicowaniu ZSON od TTN pomocna może być ultrasonografia płuc. Obecność punktu podwójnego płuca (DLP) bez konsolidacji płucnej jest najbardziej specyficzną cechą ultrasonograficzną TTN, podczas gdy główną cechą ultrasonograficzną ZSON jest konsolidacja płucna z bronchogramami powietrznymi bez DLP. Czułość DLP w diagnozie TTN wynosi 76,7%, a swoistość 100%.4243

Nowoczesne techniki diagnostyczne

Współczesne podejście do diagnostyki ZSON obejmuje nowsze, zaawansowane techniki, takie jak:44

Radiomika ultrasonograficzna

Radiomika ultrasonograficzna to nowa metoda wykorzystująca zaawansowaną analizę obrazów ultrasonograficznych do diagnozy ZSON. W jednym z badań wyselekcjonowano 22 cechy obrazowe o najwyższych wagach do budowy modelu predykcyjnego dla ZSON. Model Random Forest (RF) wykazał doskonałą wydajność diagnostyczną w analizie cech tekstury opartych na radiomice ultrasonograficznej w diagnozowaniu ZSON, przewyższając inne modele, takie jak SVM, KNN i MLP.454647

Komputerowa analiza zdjęć RTG

Badania nad zaawansowaną diagnostyką ZSON u wcześniaków leczonych surfaktantem i budesonidem poprzez komputerową analizę zdjęć RTG klatki piersiowej wykazały wysoką swoistość (0,95) i czułość (0,84) w identyfikacji przypadków ZSON. Ogólna dokładność segmentacji osiągnęła wartość 0,93, zapewniając równowagę między precyzją a czułością w prognozach.48

Podsumowanie diagnostyki ZSON

Diagnostyka zespołu stresu oddechowego noworodka wymaga kompleksowego podejścia łączącego ocenę kliniczną, wywiad prenatalny, badania obrazowe i laboratoryjne. Wczesne rozpoznanie jest kluczowe dla wdrożenia odpowiedniego leczenia, które może obejmować podanie egzogennego surfaktantu, wsparcie oddechowe oraz inne strategie ochrony płuc.495051

Nowsze metody diagnostyczne, takie jak ultrasonografia płuc i techniki oparte na radiomice, oferują obiecujące podejście do szybkiej i dokładnej diagnostyki ZSON, choć radiografia klatki piersiowej pozostaje podstawowym narzędziem diagnostycznym. Ciągły rozwój tych technik może pozwolić na jeszcze wcześniejsze rozpoznanie i bardziej ukierunkowane leczenie, potencjalnie poprawiając wyniki kliniczne u noworodków z ZSON.52

    Advanced Diagnostics of Respiratory Distress Syndrome in Premature Infants Treated with Surfactant and Budesonide through Computer-Assisted Chest X-ray Analysis […] This research addresses the respiratory distress syndrome (RDS) in preterm newborns caused by insufficient surfactant synthesis, which can lead to serious complications, including pneumothorax, pulmonary hypertension, and pulmonary hemorrhage, increasing the risk of a fatal outcome. By analyzing chest radiographs and blood gases, we specifically focus on the significant contributions of these parameters to the diagnosis and analysis of the recovery of patients with RDS. The study involved 32 preterm newborns, and the analysis of gas parameters before and after the administration of surfactants and inhalation corticosteroid therapy revealed statistically significant changes in values of parameters such as FiO2, pH, pCO2, HCO3, and BE (Sig. < 0.05), while the pO2 parameter showed a potential change (Sig. = 0.061). [...] The diagnosis of RDS is established based on typical anamnestic data, clinical findings, gas analysis, and chest radiography. Chest radiography is often considered the “gold standard” for diagnosis. The X-ray may reveal the presence of diffuse microatelectasis and characteristic changes indicating inadequately ventilated pulmonary alveoli. [...] Timely diagnosis and an appropriate therapeutic approach play a crucial role in improving the prognosis of respiratory distress syndrome. [...] The examination of the effects of surfactant and inhaled corticosteroid on the respiratory parameters of newborns provided insights into significant changes in gas analyses during therapy. A paired sample t-test analysis was applied. [...] The parameters FiO2, pH, pCO2, HCO3, and BE show statistically significant changes, considering significance values less than 0.05. [...] The segmentation results highlight a high specificity of 0.95, indicating precision in identifying negative instances. The algorithm’s sensitivity is 0.84, suggesting efficiency in recognizing positive instances. The overall segmentation accuracy reaches 0.93, providing a balance between precision and recall in predictions. [...] The results demonstrated that prior to the therapy, infants required higher fractions of inhaled oxygen. After the therapy, blood pH increased, the partial pressure of carbon dioxide decreased, and the partial pressure of oxygen increased.
  • #12 Neonatal Respiratory Distress Syndrome (RDS) Imaging: Practice Essentials, Radiography, Ultrasonography
    https://emedicine.medscape.com/article/409409-overview
    Respiratory distress syndrome (RDS) of the newborn is an acute lung disease caused by surfactant deficiency, which leads to alveolar collapse and noncompliant lungs. Neonatal RDS arises at or shortly after birth (24 hr) and increases in severity during the first 48 hours of life. RDS is usually diagnosed with a combination of clinical signs and/or symptoms, chest radiographic findings, and arterial blood gas results. A normal film at 6 hours of life excludes the diagnosis of RDS. […] Lung ultrasound score (LUS) has been described in the early phases of neonatal RDS, but LUS may potentially miss pneumothorax, pneumomediastinum, or pneumopericardium; therefore, chest radiography remains necessary for suspected neonatal RDS. […] The incidence and severity of RDS are inversely related to gestational age. RDS is the most common cause of respiratory failure during the first days after birth.
  • #13 Infant respiratory distress syndrome – Wikipedia
    https://en.wikipedia.org/wiki/Infant_respiratory_distress_syndrome
    The diagnosis is made by the clinical picture and the chest X-ray, which demonstrates decreased lung volumes (bell-shaped chest), absence of the thymus (after about six hours), a small (0.51 mm), discrete, uniform infiltrate (sometimes described as a „ground glass” appearance or „diffuse airspace and interstitial opacities”) that involves all lobes of the lung and air-bronchograms (i.e. the infiltrate will outline the larger airways passages, which remain air-filled). In severe cases, this becomes exaggerated until the cardiac borders become indiscernible (a 'white-out’ appearance). […] To improve clinical outcomes very early treatment with surfactant is necessary. However, only about half of infants with a gestational age (GA) below 30 weeks need surfactant treatment and prophylactic surfactant treatment increases the combined mortality and incidence of Bronchopulmonary Dysplasia (BPD) contrary to selective rescue surfactant treatment. Therefore, there is a need for a rapid diagnostic test to guide early targeted surfactant treatment.

  • #19 The Role of Lung Ultrasound in Diagnosis of Respiratory Distress Syndrome in Newborn Infants
    https://brieflands.com/articles/ijp-323
    Respiratory distress syndrome (RDS) is one of the most common causes of neonatal respiratory failure and mortality. The aim of this study was to evaluate the value of lung ultrasound in the diagnosis of respiratory distress syndrome (RDS) in newborn infants. In all of the infants with RDS, lung ultrasound consistently showed generalized consolidation with air bronchograms, bilateral white lung or alveolar-interstitial syndrome, pleural line abnormalities, A-line disappearance, pleural effusion, lung pulse, etc. The simultaneous demonstration of lung consolidation, pleural line abnormalities and bilateral white lung, or lung consolidation, pleural line abnormalities and A-line disappearance co-exists with a sensitivity and specificity of 100%. Besides, the sensitivity was 80% and specificity 100% of lung pulse for the diagnosis of neonatal RDS. This study indicates that using an ultrasound to diagnose neonatal RDS is accurate and reliable too. Lung ultrasound is typically not included in the diagnostic work-up of neonatal RDS. The diagnosis of RDS is usually based on clinical manifestations, arterial blood gas analysis and chest x-rays. Lung consolidation with air bronchograms was seen in every (100%) RDS infant. Lung pulse was seen in every grade III~IV RDS patient (40 cases), while 10 grade II RDS patients did not show this sign. Lung pulse is associated with the degree and the extent of lung consolidation. According to our results the sensitivity was 80% and specificity 100% of lung pulse for the diagnosis of neonatal RDS.

    https://emedicine.medscape.com/article/409409-overview
    Respiratory distress syndrome (RDS) of the newborn is an acute lung disease caused by surfactant deficiency, which leads to alveolar collapse and noncompliant lungs. Neonatal RDS arises at or shortly after birth (24 hr) and increases in severity during the first 48 hours of life. RDS is usually diagnosed with a combination of clinical signs and/or symptoms, chest radiographic findings, and arterial blood gas results. A normal film at 6 hours of life excludes the diagnosis of RDS. […] Lung ultrasound score (LUS) has been described in the early phases of neonatal RDS, but LUS may potentially miss pneumothorax, pneumomediastinum, or pneumopericardium; therefore, chest radiography remains necessary for suspected neonatal RDS. […] The incidence and severity of RDS are inversely related to gestational age. RDS is the most common cause of respiratory failure during the first days after birth.

    Professor Henrik Verder, in collaboration with chemometric scientist Agnar Hoskuldsson, developed a rapid point-of-care method for predicting IRDS by measuring the lecithin-sphingomyelin ratio (L/S) in gastric aspirate (GA). The new method, which is based on midred Fourier Transform Infrared spectroscopy, was shown to measure the L/S ratio at birth with a high sensitivity. This rapid bedside test for surfactant components in gastric aspirate is also now available, and clinical trials of this new point-of-care test to determine surfactant need at birth are underway. […] Lung ultrasound, with appropriate expertise, equipment, and training, may offer an alternative way to diagnose the severity of IRDS. A semi-quantitative lung ultrasound score performed during bedside lung echography was first described by Brat et al. and found to correlate with the oxygenation status of infants with RDS. Since then, several studies have supported the use of lung ultrasound scores to earlier predict an initial dose of surfactant when compared to current oxygenation-guided recommendations.

    Diagnosis and Management of Newborn Respiratory Distress Syndrome […] The neonatal survival of preterm babies is still improving thanks to modern technologies and newly targeted therapy approaches to pulmonary immaturity and surfactant deficiency. Respiratory Distress Syndrome (RDS) prevention starts during pregnancy, considering all the possible interventions aiming to prolong the gestation of preterm fetuses, and continues after birth. The evidence-based lung-protective strategies include the initiation of non-invasive respiratory support from birth, the judicious use of oxygen, early surfactant administration, caffeine therapy, cardiovascular assessment, and the avoidance of mechanical ventilation where possible. Lung ultrasound has replaced conventional radiology in the diagnosis of RDS, allowing neonatologists to act quickly and avoid unnecessary radiation exposure to the baby. The modern approach to RDS should be personalized, taking a physiopathology and critical care perspective, which can only be built by developing cross-disciplinary awareness in order to avoid chronic lung disease.

[…] NRDS primarily arises due to insufficient surfactant production in the immature lungs of preterm infants. […] The management of NRDS focuses on providing supportive care, optimizing oxygenation, and promoting lung maturation to mitigate respiratory compromise and improve outcomes. […] Antenatal corticosteroid therapy, administered to pregnant women at risk of preterm delivery, has been shown to enhance fetal lung maturation and reduce the incidence and severity of NRDS. […] Exogenous surfactant therapy is a cornerstone of NRDS management and is aimed at supplementing deficient surfactant levels in preterm infants.

    Non-invasive respiratory support modalities such as Nasal Continuous Positive Airway Pressure (NCPAP) and Nasal Intermittent Positive Pressure Ventilation (NIPPV) are preferred over invasive mechanical ventilation whenever possible, particularly in infants with mild-to-moderate respiratory distress. […] In severe cases of NRDS characterized by refractory hypoxemia and respiratory failure, invasive mechanical ventilation may be necessary to support gas exchange and maintain adequate oxygenation. […] Lung protective ventilation strategies aim to minimize ventilator-induced lung injury and mitigate the risk of Bronchopulmonary Dysplasia (BPD) in preterm infants with NRDS. […] Supportive care measures such as maintaining a neutral thermal environment, providing appropriate nutritional support, and monitoring fluid balance are essential components of NRDS management.

    Infants with severe NRDS requiring advanced respiratory support may necessitate transfer to a tertiary care Neonatal Intensive Care Unit (NICU) equipped with specialized resources and expertise in neonatal respiratory care. […] Early initiation of surfactant therapy, lung protective ventilation strategies, and comprehensive supportive care measures have been shown to improve outcomes and reduce the incidence of complications in infants with NRDS.
