CROUP
An upper airway infection that blocks breathing and has a distinctive barking cough.
Croup generally occurs in children.
Requires a medical diagnosis
In addition to a barking cough, symptoms include fever, hoarseness and laboured or noisy breathing.
People may experience:
Cough: can be barking
Respiratory: difficulty breathing, fast breathing, noisy breathing, shortness of breath, or wheezing
Whole body: fatigue or fever
Nasal: congestion or runny nose
Speech: hoarseness or impaired voice
Also common: agitation, drooling, phlegm, or sore throat
Most cases clear up with home care in three to five days. A doctor may prescribe a steroid for a persistent case. Rarely, a severe case may need hospital care.
Medications
Steroid, Analgesic, Nonsteroidal anti-inflammatory drug, Vasoconstrictor and Cough medicine
Supportive care
Oxygen therapy, Can be self-healing and Airway management
EPIGLOTTIS
A potentially life-threatening condition that occurs when the tissue protecting the windpipe becomes inflamed.
Epiglottitis is commonly caused by an infection. The resulting inflammation causes swelling, which blocks air to the lungs.
Symptoms
Requires a medical diagnosis
Symptoms often include shortness of breath, difficulty swallowing and sore throat. Fever is commonly seen in cases of infection.
People may experience:
Pain circumstances: can occur while swallowing
Respiratory: noisy breathing or shortness of breath
Throat: soreness or difficulty swallowing
Also common: fever, coughing, drooling, impaired voice, or swollen lymph nodes
Treatment consists of supportive care and antibiotics
When an infection is present, treatment includes antibiotics. A breathing tube and ventilator may be required in severe cases.
Medications
Antibiotics and Penicillin
Supportive care
Airway management and IV fluids
RSV
Respiratory syncytial virus (RSV) causes infections of the lungs and respiratory tract. It's so common that most children have been infected with the virus by age 2. Respiratory syncytial (sin-SISH-ul) virus can also infect adults.
In adults and older, healthy children, RSV symptoms are mild and typically mimic the common cold. Self-care measures are usually all that's needed to relieve any discomfort.
Symptoms
Signs and symptoms of respiratory syncytial virus infection most commonly appear about four to six days after exposure to the virus. In adults and older children, RSV usually causes mild cold-like signs and symptoms. These include:
Congested or runny nose
Dry cough
Low-grade fever
Sore throat
Mild headache
In severe cases
Respiratory syncytial virus infection can spread to the lower respiratory tract, causing pneumonia or bronchiolitis — inflammation of the small airway passages entering the lungs. Signs and symptoms may include:
Fever
Severe cough
Wheezing — a high-pitched noise that's usually heard on breathing out (exhaling)
Rapid breathing or difficulty breathing — the child may prefer to sit up rather than lie down
Bluish color of the skin due to lack of oxygen (cyanosis)
Infants are most severely affected by RSV. You may notice your child's chest muscles and skin pull inward with each breath. This is a sign that he or she is struggling to breathe. Other signs and symptoms of severe RSV infection in infants include:
Short, shallow and rapid breathing
Cough
Poor feeding
Unusual tiredness (lethargy)
Irritability
Treatment
The doctor may recommend an inhaled form of an antiviral medicine called ribavirin (Virazole) for people with very weakened immune systems (immunocompromised). An inhaler (bronchodilator) or steroids are not proved to be helpful in treating RSV infection
