Asthma is a disease resulting in mucus hypersecretion and airways obstruction. This causes difficulty breathing. The High Frequency Chest Compressor (HFCC) is a device that has been shown to decrease respiratory complications in individuals with severe disability who are unable to clear airway secretions. There is a lack of studies using this device in children with asthma. The device has been shown in a study to be safe in children with asthma. The investigators propose that using this device in our pediatric patients hospitalized in the pediatric ICU with asthma will result in decreased pediatric ICU stay. The investigators will also look at asthma severity, total days of hospital stay and chest discomfort while on therapy.

Condition Intervention
Pediatric, Asthma, Acute Exacerbation, Pediatric ICU
Device: High Frequency Chest Compression VEST

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Use of High Frequency Chest Compression (HFCC) in Pediatric Status Asthmaticus

Further study details as provided by Texas Tech University Health Sciences Center:

Primary Outcome Measures:
  • Hours Spent in Pediatric ICU [ Time Frame: Number of hours from admission to discharge from PICU ]
    Length of stay (hours) in Pediatric ICU.

Secondary Outcome Measures:
  • Total Days of Hospital Admission [ Time Frame: Days ]
    This is limited due to non collection by collaborating centers.

  • Pediatric Asthma Severity Score (Modified Pulmonary Index Score) [ Time Frame: Discharge from PICU ]
    Modified Pulmonary Index Score (MPIS): a validated asthma severity score in pediatric population (Carroll CL et al. A modified pulmonary index score with predictive value for pediatric asthma exacerbations, Ann Allergy Asthma Immunol 2005) Consists of: 1) oxygen saturation on room air 2) accessory muscle use 3) inspiratory to expiratory ratio 4) degree of wheezing 5) heart rate 6) respiratory rate Scored observations 0, 1, 2 or 3. Total score range 0 - 18. Mild exacerbation total less than 6, moderate exacerbation 6 - 10, severe exacerbation higher than 10

  • Number of Participants With Chest Discomfort [ Time Frame: During PICU admission ]

Enrollment: 36
Study Start Date: October 2007
Study Completion Date: September 2014
Primary Completion Date: July 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Use of the HFCC device in addition to standard therapy for status asthmaticus. The use of HFCC will not affect the therapy received
Device: High Frequency Chest Compression VEST
every 6 hours for 20 minutes
No Intervention: 2
This group will not use the VEST or HFCC. They will just have standard therapy for status asthmaticus. The standard therapy will not be affected if they are in this group.
