  39. 39. ED: Salbutamol Nebulizer –cont 1hour Oxygen mask IV hydrocortisone Ipratropiumbromide: 4hourly IV fluid-maintainance Blood investigation: FBC, VBG, electrolyte If not, IV salbutamoloraminophyline If the symptoms persist, intubation. Monitoring: vital signs, SpO2, VBG Syrup prednisolone 17mg OD 5/7                 mdifluticasone 125mcg BD mdisalbutamol 200mg 4 hourly At home: Avoid allergens syrup prednisolone MDI Salbutamol
  41. 41. Chronic inflammatory disorder of airways that causes recurrent episodes of wheezing, breathlessness, chest tightness and coughing. DEFINITION
  42. 42. RISK FACTORS Host Factors Genetic predisposition Atopy Airway hyper- responsiveness Gender Race/Ethnicity Environmental Factors Indoor /allergens Socioeconomic factors Family size weather changes Obesity
  43. 43. TRIGGERS FACTORS Allergens Smoke (passive smoker) Respiratory infections Exercise and hyperventilation Emotional upset or excitement Food, additives, drugs
  44. 44. Pathogenesis of asthma Enviromental factors Genetic factors Bronchial inflamation Bronchial hyperactivity + trigger factors Oedema , bronchononstriction, & increase mucous production Airways narrowing Symptoms: -cough -wheezing -breathlessness -chest tightness
  45. 45. CLINICAL FEATURES Cough Chest tightness Wheezing sound of breath Episodic shortness of breath Worsen during night
  46. 46. Various severities of asthma Classification of asthma severity - Mild intermittent - Mild persistent - Moderate persistent - Severe persistent *In this patient, it is mild intermittent.
  47. 47. *Patient only developed asthma once in two month.
  48. 48. DIAGNOSIS History and patterns of symptoms Physical examination Measurements of lung function Measurements of allergic status to identify risk factors
  49. 49. TAKING HISTORY Since when it start & previous attack? -since 4 years old, once in 2 months, last attack was on October Aggravating and relieving factors? -cold drinks, cold weather or do vigorous exercise Have any prolong URTI sx? - No significance Prev hospital administration? - No hospital administration before this. History of atopy? - No eczema Family history of asthma? -Strong family hx of asthma Impact on lifestyle? -Not impact patient lifestyle as he only developed mild intermittent asthma
  50. 50. PHYSICAL EXAMINATION OBSERVATION -(tachypnic, wheezing, drowsiness, central cyanosis, hyperinflated chest, head bobbing, peripheral cyanosis, using accessory muscle when breathing, SCR ,ICR & suprasternal recession) PALPATION - Decrease symetrically chest wall expansion PERCUSSION -resonance AUSCULTATION -(reduced breath sound, rhonci, vesicular breath sound with prolong expiration time)
  51. 51. INVESTIGATION1)LUNG FUNCTION TEST This can be done by using Peak Expiratory Flow Rate(PEFR).
  52. 52. 2)Blood and sputum test.3)Chest X-ray. Asthmatic patient may have increase number of neutrophils in pheripheral blood Helpful in excluding a pneumothorax / pneumonia.
  53. 53. Criteria for admission failure to respond to standard home treatment Failure of those with mild or moderate acute asthma to respond to nebulised B2-agonist. Relapse within 4 hours of nebulised B2-agonist. Severe acute asthma * This patient was admitted to ward because failed respond towards the nebulisersalbutamol given in the ED.
  54. 54. Common management for AEBA Gives neb oxygen + neb salbutamol + neb ipratopium bromide + IV hydrocortisone + hydration – IV normal saline If symptoms not subside, gives IV salbutamol If symptoms still not subside, do endotracheal intubation and gives mechanical ventilation.
  55. 55. MANAGEMENT Give drug treatment to the patient by following the severity of the asthma. Hydration-give maintenance fluid Monitor pulse, colour, PEFR, VBG and SPO2. (4 hrly) Antibiotic indicated only if bacterial infection suspected Avoids sedatives and mucolytics Health education involving the parents and their asthmatic child. -how to recognized & treat worsening asthma -when to seek for medical attention -how to used MDI correctly
  56. 56. Impact of asthma Night cough, disturbed sleep Restriction in activity / exercise Increased school absences (not able to pay attention in the class, academic performance will drop) Ongoing symptoms may have a detrimental effect on physical, psychological and social well-being * Patient only had continuous night cough and sleeping disturbance during the attack.
  57. 57. Acute severe asthma Inability to complete a sentence in one breath. Respiratory rate >50/min Tachycardia >140/min PEFR <50% from normal
  58. 58. LIFE-THREATENING ASTHMA Silent chest and cyanosis. Exhaustion,confusion or coma. PEFR <33% of prediction.
  59. 59. PREVENTION Education of the family members is a vital role : - teaching basic asthma facts - explain role of medication given - teaching environmental control measures - improving parents skills in the use of spacer device MDI. *in this case, the parents of the patient did not know how to use the device & his father is a smoker
  60. 60. COMPLICATION STATUS ASTHMATICUS -Is an acute exacerbation of asthma attack which do not respond adequately to therapeutic measures and required hospitalization
