II. Evaluation: Vital Sign Monitoring
-
Vital Signs: Temp, Pulse, Blood Pressure, Respirations
- Start with every 4 hours for 12 hours
- Space to every 6 hours
- Peak Expiratory Flow (PEFR)
-
Oxygen Saturation Monitor
- Oxygen to keep Oxygen Saturation adequate
- Adults: >90%
- Children: >95%
- Discontinuation Criteria
- Oxygen Saturation adequate for 4 hours
- Patient on general ward
- Continue spot check Oxygen Saturation
- Perform with Vital Signs
- As needed for respiratory distress
- Oxygen to keep Oxygen Saturation adequate
- Telemetry monitor (cardiac monitor) Indications
- Albuterol Nebulizer more than every 4 hours
- Infant or young child
- Corroborate Oxygen Saturation monitor (match pulse)
- Child movement makes Oxygen Saturation inaccurate
III. Management: Medications
- See Albuterol Nebulizer dose
-
Corticosteroids
- Methylprednisolone (Solu-medrol)
- Dose: 1 mg/kg/dose q6 hours
- Maximum Dose: 60 mg IV q6 hour OR 80 mg IV q8 hours
- Oral Prednisone
- Indications to switch from Solu-medrol
- Albuterol Nebulizer spaced to 4 hours or more
- Tolerating oral intake (No Nausea or Vomiting)
- Dose
- Prednisone 1-2 mg/kg/day qd-bid
- Maximum: 40-60 mg/day for 5-10 days
- No tapering needed if use less than 2 weeks
- Indications to switch from Solu-medrol
- Methylprednisolone (Solu-medrol)
IV. Evaluation: Monitoring
-
Arterial Blood Gas Indications (on admission)
- Pulmonary Function Test Criteria
- PEFR < 30%
- Prior history of pCO2 > 40
- Failure to improve in 4 hours of therapy
- Clinical Asthma score >7
- Pulmonary Function Test Criteria
- Indications to monitor serum electrolytes
- Nausea or Vomiting
- Intravenous Fluids for more than 24 hours
- Beta agonists more than every 4 hours for 24 hours
- Chest XRay Indications
V. Evaluation: Signs of Improvement
- Minimal or no Wheezing
- Less than 2 night awakenings for Mild Asthma symptoms
- Good activity tolerance
-
Pulmonary Function Test criteria
- PEFR or FEV1 >= 70% of baseline
- Adequate Oxygen Saturation off Supplemental Oxygen
VI. Management: More Intensive Treatment Options
- Intensive care unit for no improvement in 6-12 hours
- See Status Asthmaticus
VII. Management: Preparation for Discharge
- Asthma-Related Death Risk Factors
- Inhaled Beta Agonist no more then q4 hours
- Parenteral steroids switched to Oral Corticosteroids
- Adequate Oxygen Saturation on room air
-
Asthma Education: Medication use
- Inhaled Corticosteroid by bedside
- Respiratory Therapy or nurse to instruct use bid
- Peak Flow measurement at home
- Follow-up in clinic in 7-10 days
