Pertussis (Whooping Cough)

Image
Definition Pertussis (Whooping Cough) is an acute disease of the respiratory tract. Found in children younger than 5 years, especially in children age 2-3 years. Cause Pertussis is caused by gram-negative Bordetella Pertussis. Clinical Overview These symptoms occur 1-2 weeks after contact with the infected person and preceded by an incubation period of 7-14 days. Typically, the disease lasts for 6 weeks or more. That is why the disease is called cough hundred days. On his way, pertussis includes several stages, namely: Kataralis which marked the onset of a mild cough, especially at night, accompanied by mild fever and runny nose. This stage lasts 1-2 weeks. In the catarrhal stage indistinguishable from that caused by a viral respiratory infection Second is the spasmodic stage lasts 2-4 weeks. Symptoms, cough more often, people with sweat, and blood vessels in the face of wide-neck. Long coughing attack usually ends with a distinctive high-pitched sound (whooping caugh) and accompanied ...

Management of Cough

Image
The best management of cough is best to specific drug delivery to the etiology. Three forms of management of cough are: 1. Without the drug delivery Cases with a cough without the interference caused by acute illness and heal itself usually does not need medication. 2. Specific Treatment This treatment is given to the causes of cough . If the cause of cough is known then the treatment should be directed towards the cause. With an integrated diagnostic evaluation, in almost all patients can be a known cause of chronic cough . Specific treatment depends on the etiology or the cough mechanism. Asthma treated with bronchodilators or corticosteroids. Post nasal drip due to sinusitis treated with antibiotics, nasal spray and antihistamine-decongestant combinations, post nasal drip due to allergies or non allergic rhinitis dealt with avoiding environments that have the precipitating factors and antihistamine-decongestant combinations. Gastroesophageal reflux treated by elevating the head,...

Cough - Causes and Complications

Image
Cough Reflex Cough reflex consists of five main components, ie, cough receptors, afferent nerve fibers, central cough, nervous system and efferent effectors. A cough begins with a stimulus on cough receptor. These receptors are non-myelinated nerve fibers in the form of finely located both inside and outside the thoracic cavity. Located within the thoracic cavity, among others, contained in the larynx, trachea, bronchi and the pleura. Will decrease the number of receptors on the branches of a small bronchus, and a large number of receptors found in the larynx, trachea, carina and bronchus branching region. The receptors are also found even in the ear canal, stomach, hilum, paranasalis sinus, pericardial and diaphragm. The most important afferents exist in the branch of the vagus, which excitatory flow of the larynx, trachea, bronchus, pleura, stomach, and also stimulate the ear through the Arnold branch of n. Vagus. Trigeminal nerve stimulation of the sinus paranasalis channeling, c...

Cough - Definition and Mechanisms

Image
Cough Cough is a symptom of the most common disease in which the prevalence was found in about 15% in children and 20% in adults. One out of ten patients who visited the doctor's office each year has a chief complaint of cough. Coughing can cause bad feelings, sleep disorders, affecting daily activities and reduce quality of life. Cough is a complex physiological reflex that protects the lung from mechanical trauma, chemical and temperature. Coughing is also a natural defense mechanism of lung airway to keep it clean and open to the street: Prevent the entry of foreign objects into the respiratory tract. Remove foreign objects or abnormal secretions from the respiratory tract. Coughing becomes physiologically when perceived as a nuisance. Such a cough is often a sign of a disease within or outside the lungs and sometimes are the early symptoms of a disease. Cough may be very significant on the transmission of disease through the air (air-borne infection). Cough is one of the sympto...

Lung Defense Mechanism

Image
Lung defense mechanisms are very important in explaining the occurrence of respiratory infections. lung has defense mechanisms to prevent bacteria from entering into the lungs. cleaning mechanism are: 1. Cleaning mechanism in the conductive airways , including: • Reepitelisasi airway • The flow of mucus on the surface epithelium • Bacteria naturally or "epithelial-cell binding site analogue" • Local humoral factors (IgG and IgA) • Components of the local microbial • Mucosilliar transport system • Sneezing and coughing reflexes Upper respiratory tract (nasopharynx and oropharynx) is a defense mechanism through the barrier against the entry of the anatomy and mechanism of pathogenic microorganisms. Cilia and mucus push microorganisms out of the way coughed or swallowed. If there is dysfunction of cilia as in Kartagener's syndrome, the use of nasogastric tube and pipe nasotracheal long can disrupt the flow of secretions that have been contaminated with pathogenic bacteria. ...

Anesthesia Patients With Asthma

Image
Pre-operation / Pre-anesthesia Assessment Anamnesis History about whether patients had received previous anesthesia is very important to know if there are things that need special attention, for example: allergies, nausea, vomiting, itching or shortness of breath after the surgery, so that we can design the next anesthetic well. Physical examination State of dentition examination, action open mouth, the tongue is relatively large is very important to know whether the action would make it difficult laryngoscopy intubation. Another routine systemically check about the general course should not be missed such as inspection, palpation, percussion and auscultation of all organ systems of patients. Examination of inspection, palpation, percussion and auscultation on the cardiopulmonary system is a major clinical examination of much help in the assessment of asthma . With this examination can be known frequency of breathing, respiratory pattern, presence of wheezing / ronchi. ECG examination...

Pulmonary Edema

Image
Definitions Edema , in general, means swelling. This typically occurs when fluid from the inside of blood vessels leak out of blood vessels into surrounding tissues, causing swelling. This can occur because of too much pressure in blood vessels or there is not enough proteins in the blood stream to hold the liquid in the plasma (part of blood that does not contain any blood cells). Pulmonary Edema is the term used when edema occurs in the lungs. The area immediately outside of the small blood vessels in the lung occupied by air pockets are very small, called alveoli. This is where oxygen from the air through which blood is taken by, and carbon dioxide in the blood released into the alveoli to exhaled out. Normal alveoli have very thin walls that allow air exchange, and liquids are usually kept away from the walls of the alveoli-dindig unless it loses its integrity. Pulmonary edema is an accumulation of fluid in the lungs due to sudden increase in intravascular pressure. Pulmonary ed...

Respiratory Failure

Image
Respiratory failure is the inability of the respiratory system to maintain normal blood oxygenation (PaO 2 ), elimination of carbon dioxide (PaCO 2 ) and pH Adequate ventilation problem caused by diffusion or perfusion. Respiratory failure is inadequate gas exchange to hypoxia, hypercapnia (increased arterial carbon dioxide concentration), and acidosis. Respiratory failure occurs when the exchange of O 2 to CO 2 in the lungs can not maintain the rate of O 2 consumption and CO 2 formation in the body's cells causing pO 2 <> 2> 45 mmHg (hypercapnia) (Smeltzer, C Susane, 2001) Causes / Etiology 1. The central nervous system depression Resulting in respiratory failure due to inadequate ventilation. Respiratory centers that control breathing, located below the brain stem (pons and medulla) so slow and shallow breathing. 2. Primary neurological disorder May hamper respiratory function. Impulses arising in the respiratory center spreads through the nerves that extend from ...

Benefits and Risk of Asthma Drugs

Image
Talk about the asthma medication, not separated from the wide selection of types of drugs available. Starting from the class of drugs, intended use, as well as dosage forms. Different classes of drugs will show different effects. Different effects will affect the intended use, whether the drugs used to prevent or to cope with current asthma relapse. While the dosage form influencing onset (time taken from drug to drug consumption have an effect) and the effectiveness of medications so usually adjust to the goals of treatment and the patient's condition. But keep in mind the drug in addition to having the benefit, of course not separated from the risk of side effects . Class of steroids . Examples of drugs known as steroids include budesonide , dexamethasone and beclometason . First-line drugs in asthma therapy is commonly used for the purpose of preventing a recurrence of asthma . But can also to address the current state of asthma relapse. In preventive therapy that requires ...

Pulmonary Embolism

Image
Pulmonary embolism is the obstruction of one or more pulmonary artery by a thrombus originating from somewhere. (Brunner and Suddarth) Pulmonary embolism (PE) is a blockage of the main artery of the lung or one of its branches by a substance That has Travelled from elsewhere in the body through the bloodstream (embolism). (Wikipedia) Causes Most cases of pulmonary embolism according to Brunner and Suddarth caused by 1. Blood clot 2. Air bubble 3. Fat 4. Tumor cells Pulmonary Embolism (PE) Overview Causes Clinical Manifestations Pathophysiology Diagnostic Examination Investigations Complication Medical Management Clinical Manifestations The symptoms of pulmonary embolism depends on the size of the thrombus and the area of ​​the pulmonary artery is clogged by a thrombus. The symptoms may be nonspecific. Chest pain is the most common symptom and usually has a sudden onset and is pleuritic. Subternal sometimes can and can mimic angina pectoris or myocardial infarction. Dyspnea is the sec...

Radiological Abnormalities of Atelectasis

Image
When the whole lung is deflated, there will be a homogeneous shadow on the sides of it, to heart and went to the department's trachea and the diaphragm lifted. When only one lobe of the atelaktasis caused by bronchial obstruction, may appear two characteristic abnormalities. The first abnormality is a shadow of a homogeneous than the deflated lobe itself, which will occupy a smaller space than when it develops at all. A right upper lobe collapse would appear as an opaque area at the top, with a limit that is strictly concave beneath the clavicle near the fissures caused by the raised horizontalis. The left upper lobe usually includes Lingula when deflated, and the resulting image is less firm without the firm lower limit. But in the lateral projection would seem a tongue-shaped shadow with a peak near the diaphragm; anteriorly, it may be up to the sternum, or may be separated by a translucent area of ​​the lungs caused by a slip right next to them and the sternum posterior shadow I...
