Zakażenie klatki piersiowej
Objawy

Zakażenie klatki piersiowej obejmuje infekcje płuc i dróg oddechowych, często powikłujące przeziębienie lub grypę, szczególnie w sezonie jesienno-zimowym. Objawy różnią się w zależności od etiologii (bakteryjna, wirusowa, grzybicza), wieku pacjenta i stanu ogólnego. Typowe symptomy to kaszel mokry z odkrztuszaniem zielonej lub żółtej wydzieliny, duszność, gorączka powyżej 38°C, ból w klatce piersiowej, tachykardia oraz objawy ogólnoustrojowe jak bóle mięśniowe i zmęczenie. Bakteryjne zakażenia charakteryzują się nagłym początkiem, wysoką gorączką do 40,5°C, krwistą wydzieliną i cięższym przebiegiem, natomiast wirusowe rozwijają się stopniowo z łagodniejszymi objawami. W przebiegu zapalenia płuc wyróżnia się cztery fazy: przekrwienia, czerwonego i szarego wątrobienia oraz fazę rezolucji, z typowym czasem trwania objawów od 7 do 10 dni, a kaszlu nawet do 3 tygodni. U osób starszych i z chorobami przewlekłymi rekonwalescencja może trwać 6-8 tygodni lub dłużej.

Zakażenie klatki piersiowej – Objawy

Zakażenie klatki piersiowej to infekcja, która dotyka płuca lub drogi oddechowe. Często rozwija się jako powikłanie po przeziębieniu lub grypie, szczególnie w okresie jesienno-zimowym. 12 Objawy zakażenia klatki piersiowej mogą być różnorodne – od łagodnych do ciężkich, a ich nasilenie zależy od wielu czynników, w tym wieku pacjenta, ogólnego stanu zdrowia oraz tego, czy infekcja jest wywołana przez bakterie, wirusy czy grzyby.3

Główne objawy zakażenia klatki piersiowej

Do najczęstszych objawów zakażenia klatki piersiowej należą:45

  • Kaszel mokry (często z odkrztuszaniem zielonej lub żółtej wydzieliny)
  • Duszność lub przyspieszone, płytkie oddychanie
  • Świszczący oddech
  • Gorączka (temperatura powyżej 38°C)
  • Ból lub dyskomfort w klatce piersiowej, nasilający się podczas kaszlu lub głębokiego oddychania
  • Przyspieszona akcja serca (tachykardia)
  • Ból głowy
  • Bóle mięśniowe
  • Uczucie zmęczenia

Dodatkowo mogą wystąpić inne objawy ogólnoustrojowe, takie jak pocenie się, utrata apetytu oraz bóle stawów i mięśni.67

Różnice między zakażeniem bakteryjnym a wirusowym

Objawy mogą się różnić w zależności od tego, czy zakażenie klatki piersiowej jest wywołane przez bakterie czy wirusy:89

Bakteryjne zakażenie klatki piersiowej:

Wirusowe zakażenie klatki piersiowej:

  • Zwykle rozwija się powoli, w ciągu kilku dni
  • Początkowe objawy przypominają grypę: gorączka, suchy kaszel, ból głowy, bóle mięśni
  • W ciągu 1-2 dni objawy nasilają się
  • Nasilający się kaszel i duszność
  • Możliwy świszczący oddech
  • Często ma łagodniejszy przebieg niż zakażenie bakteryjne

Przebieg zakażenia klatki piersiowej

Zakażenie klatki piersiowej najczęściej rozwija się po przeziębieniu lub grypie. Przebieg infekcji może być różny w zależności od typu zakażenia, wieku pacjenta i jego ogólnego stanu zdrowia.1011

Fazy rozwoju zakażenia

W przypadku zapalenia płuc, które jest jednym z rodzajów zakażenia klatki piersiowej, można wyróżnić cztery etapy infekcji:12

  1. Faza przekrwienia – początkowa faza charakteryzująca się mokrym kaszlem, bólem w klatce piersiowej i gorączką. Objawy mogą pojawić się nagle lub stopniowo, szczególnie gdy zapalenie płuc rozwija się jako powikłanie po innej infekcji.
  2. Faza czerwonego wątrobienia – występuje po około 2-3 dniach od pojawienia się infekcji. W tej fazie dochodzi do nacieku krwinek czerwonych i innych komórek immunologicznych do płuc. Objawy są bardziej nasilone, w tym: kaszel z gęstą, żółto-zieloną, czasem podbarwioną krwią wydzieliną, wysoka gorączka z dreszczami, silna duszność, sinica, skrajne zmęczenie.
  3. Faza szarego wątrobienia – pojawia się około 4-6 dni po rozwinięciu się infekcji. Czerwone krwinki zaczynają się rozpadać, a płuca przybierają szarawy kolor. Oddychanie może być szczególnie utrudnione.
  4. Faza rezolucji – końcowa faza charakteryzująca się gojeniem dróg oddechowych i zmniejszeniem częstotliwości oraz nasilenia objawów.

Czas trwania objawów

Większość zakażeń klatki piersiowej ma łagodny przebieg i ustępuje samoistnie w ciągu 7-10 dni.1314 Jednak kaszel i wydzielina mogą utrzymywać się do 3 tygodni.15

W przypadku ostrego zapalenia oskrzeli czas trwania objawów wynosi zwykle 7-10 dni, jednak kaszel może utrzymywać się przez 2-3 tygodnie, a w niektórych przypadkach nawet do 8 tygodni.1617

Zapalenie płuc ma dłuższy czas trwania:1819

  • U zdrowych osób – objawy mogą ustępować w ciągu 2-3 tygodni
  • U osób starszych i z problemami zdrowotnymi – okres rekonwalescencji może trwać 6-8 tygodni lub dłużej
  • W przypadku bakteryjnego zapalenia płuc – poprawa zwykle następuje w ciągu 24-48 godzin od rozpoczęcia leczenia antybiotykami
  • W przypadku wirusowego zapalenia płuc – poprawa jest bardziej stopniowa

Zdjęcie RTG klatki piersiowej może wykazywać zmiany jeszcze przez 6-12 tygodni.20

Objawy poprawy zakażenia klatki piersiowej

Oznaki wskazujące na ustępowanie zakażenia klatki piersiowej obejmują:2122

  • Zmniejszenie produkcji wydzieliny
  • Rzadszy kaszel
  • Brak gorączki lub dreszczy
  • Poprawa poziomu energii
  • Mniejszy ból w klatce piersiowej
  • Poprawa poziomu tlenu we krwi
  • Mniejsza duszność
  • Zmniejszenie bólu głowy
  • Ustąpienie objawów żołądkowo-jelitowych (nudności, wymioty, biegunka)

Pomimo poprawy objawów, uczucie zmęczenia może utrzymywać się nawet przez miesiąc.23

Objawy alarmowe wymagające konsultacji lekarskiej

Chociaż większość zakażeń klatki piersiowej ustępuje samoistnie, niektóre objawy powinny skłonić do niezwłocznej konsultacji z lekarzem. Do objawów alarmowych należą:242526

  • Silna duszność lub trudności w oddychaniu
  • Ból w klatce piersiowej nasilający się podczas oddychania lub kaszlu
  • Odkrztuszanie krwi lub śluzowiny podbarwionej krwią
  • Wysoka gorączka (powyżej 38°C) utrzymująca się dłużej niż kilka dni
  • Sinica – niebieski odcień skóry, warg lub paznokci
  • Splątanie lub zaburzenia świadomości
  • Objawy nieustępujące po 3 tygodniach
  • Nasilenie objawów pomimo leczenia

Niezwłocznej pomocy medycznej wymagają również osoby z grup podwyższonego ryzyka, w tym:2728

  • Osoby powyżej 65. roku życia
  • Dzieci poniżej 2. roku życia
  • Osoby z obniżoną odpornością
  • Pacjenci z chorobami przewlekłymi (szczególnie chorobami układu oddechowego i krążenia)

Możliwe komplikacje nieleczonego zakażenia klatki piersiowej

Nieleczone lub niewłaściwie leczone zakażenie klatki piersiowej może prowadzić do poważnych powikłań, takich jak:293031

  • Niewydolność oddechowa
  • Wysięk opłucnowy – gromadzenie się płynu wokół płuc
  • Zapalenie opłucnej (pleurisy) – stan zapalny błony wyściełającej jamę klatki piersiowej
  • Ropień płuca
  • Posocznica (sepsa) – niekontrolowany stan zapalny w całym organizmie
  • Pogorszenie istniejących chorób przewlekłych, takich jak astma czy przewlekła obturacyjna choroba płuc (POChP)

W przypadku bakteryjnego zapalenia oskrzeli może dojść do rozwoju zapalenia płuc.32

Różnice w objawach w zależności od wieku i stanu zdrowia

Objawy zakażenia klatki piersiowej mogą się różnić w zależności od wieku pacjenta i jego ogólnego stanu zdrowia.3334

Objawy u niemowląt i małych dzieci

U niemowląt i małych dzieci objawy zakażenia klatki piersiowej mogą być inne niż u dorosłych:353637

  • Brak wyraźnych objawów u noworodków i niemowląt
  • Wymioty
  • Gorączka
  • Brak apetytu lub trudności z karmieniem
  • Niepokój lub rozdrażnienie
  • Letarg i senność
  • Przyspieszone oddychanie – może być to jedyny objaw
  • Wciąganie przestrzeni międzyżebrowych podczas oddychania
  • Chrząkające dźwięki podczas oddychania
  • Biegunka

W przypadku zapalenia oskrzeli u dzieci może wystąpić mokry, „szczekający” kaszel, który staje się uciążliwy szczególnie w nocy.38

Objawy u osób starszych i z obniżoną odpornością

U osób starszych (powyżej 65. roku życia) oraz u pacjentów z obniżoną odpornością objawy zakażenia klatki piersiowej mogą być łagodniejsze lub atypowe:394041

  • Nagła zmiana stanu psychicznego, splątanie lub dezorientacja
  • Niższy apetyt
  • Zmęczenie
  • Mniej wyraźne lub łagodniejsze objawy kaszel i duszność
  • Niższa od normalnej temperatura ciała
  • Nasilenie objawów chorób współistniejących

U osób starszych zapalenie płuc może szybko stać się stanem zagrażającym życiu.42

Objawy związane z ciężkim przebiegiem

Objawy wskazujące na ciężki przebieg zakażenia klatki piersiowej, które mogą wymagać hospitalizacji, to:4344

  • Hipoksja (obniżony poziom tlenu w organizmie) objawiająca się sinicą, przyspieszonym oddechem i tętnem, splątaniem
  • Silna duszność uniemożliwiająca normalne funkcjonowanie
  • Trudności z przyjmowaniem płynów i leków doustnych
  • Brak poprawy pomimo leczenia ambulatoryjnego
  • Nasilona świadomość chorobowa – uczucie silnego osłabienia, zmęczenia
  • Trudności z oddychaniem wymagające tlenoterapii lub wentylacji mechanicznej

W ciężkich przypadkach mogą wystąpić również dreszcze i sztywność mięśniowa (rigors).45

Przebieg czasowy zakażenia klatki piersiowej

Typowy przebieg czasowy zakażenia klatki piersiowej przedstawia się następująco:464748

  • 1-4 dni: Pojawienie się pierwszych objawów – często przypominających przeziębienie lub grypę (katar, ból gardła, kaszel)
  • 3-5 dni: Nasilenie objawów – kaszel staje się bardziej produktywny, pojawia się wydzielina, duszność, gorączka
  • 7-10 dni: U większości pacjentów z łagodnym zakażeniem klatki piersiowej objawy zaczynają ustępować
  • 2-3 tygodnie: Kaszel i odkrztuszanie wydzieliny mogą się utrzymywać, nawet gdy inne objawy ustąpią
  • 1 miesiąc lub dłużej: Uczucie zmęczenia może się utrzymywać, szczególnie u osób starszych lub z chorobami współistniejącymi

W przypadku bakteryjnego zapalenia płuc pierwsza poprawa powinna nastąpić w ciągu 24-48 godzin od rozpoczęcia antybiotykoterapii.49 Natomiast w przypadku wirusowego zapalenia płuc poprawa następuje bardziej stopniowo, w ciągu kilku dni od rozpoczęcia leczenia.50

Nawracające zakażenia klatki piersiowej, które nie ustępują mimo leczenia lub występują w krótkich odstępach czasu, mogą wskazywać na poważniejsze problemy zdrowotne i wymagają konsultacji lekarskiej.51

Odpowiednie rozpoznanie objawów zakażenia klatki piersiowej oraz ich progresji pozwala na wdrożenie właściwego leczenia i zmniejszenie ryzyka powikłań. W przypadku wystąpienia objawów alarmowych, należy niezwłocznie skonsultować się z lekarzem.

  • #38 Chest Infections In Children | Respiratory Infections
    https://www.childrensrespiratorydoctor.co.uk/chest-infections.php
    Viral or bacterial infections in the lungs or air passages that can happen after a cold or the flu are often called chest infections. The most obvious sign of a chest infection is a persistent cough, which usually appears after a milder cold or the flu. Coughs caused by chest infections in child patients often sound wet and chesty. Other symptoms may include a fever, wheezing, and coughing up phlegm or mucus. The coughing associated with chest infection in child patients can sometimes cause them to retch or throw up because they are straining to cough so much. The symptoms can vary depending on the exact location of the chest infection. Bronchitis, an infection in the main airways (bronchial tubes) that supply the lungs, is particularly likely to cause a wet, hacking cough that brings up green or yellow phlegm. Pneumonia, which is an infection in the lungs, may cause additional symptoms such as breathlessness, rapid breathing, and chest pain. Most chest infections in children will get better by themselves in a few days or weeks, but some can cause serious complications. Children should start to improve within a week to 10 days, but the cough can last for four to six weeks. Chest infections can cause severe symptoms such as breathing difficulty in children. You might notice that your child is breathing faster than usual, breathing noisily, or having to work much harder to breathe. Sometimes these breathing difficulties can tire your child out or make it harder for them to eat and drink properly. Chest infections can also develop into more serious complications. Children can develop cyanosis, which causes their skin or lips to turn blue because they aren’t getting enough oxygen. The respiratory symptoms can also be so severe that children need extra oxygen or help to breathe. A mild chest infection or bronchitis can develop into a more serious one, such as pneumonia. Although pneumonia can often be relatively mild, it can cause stronger symptoms and there is a risk of worse complications. Possible complications of pneumonia include blood poisoning and pleurisy, which is inflammation of the membranes that surround your lungs. You should always consult a doctor if your child is under the age of five and you think that he or she has a chest infection. Older children won’t usually need to see a doctor for a mild chest infection, but you should still seek medical advice if the symptoms are very severe or they last for more than a few weeks. Signs that a chest infection is very serious and requires immediate medical attention include a very high fever, difficulty breathing, blueness around the lips, and confusion or disorientation. Chest infections can usually be diagnosed based on your child’s symptoms and by listening to his or her chest with a stethoscope. The treatment will depend on how severe the symptoms are and on the cause of the infection. If the symptoms are very severe or your child develops complications, additional treatment may be needed in hospital.
