Detailed Description
Once each patient legal guardians has signed the informed consent document and it has been verified that the inclusion criteria are met, it will be assigned the same identification number (ID) that is related to its Clinical History (CH) by simple coding; custody of the file with the relationship of each ID with its CH will be the responsibility of the principal investigator.
The assignment will be made at the time of query according to a table of random numbers previously established and that it will only be known by physiotherapists.
Before starting the treatment protocol, a blind evaluator who does not know the treatment to which the patient is assigned, classifies the child according to the initial score of clinical severity proposed by Wang, in addition to the measurement of SO2 and frequency heart rate through a pulse oximeter. The measurement of the amount of sputum collected in a meter measuring cup, once the respiratory physiotherapy session is finished, it will be done in a calibrated weight in both groups.
The protocol in the manual maneuvers group consists of 20 minutes of FR based on prolonged slow expiration and coughing provoked. Is apassive technique of expiratory help applied to the baby through a slow thoracic-abdominal pressure that begins at the end of spontaneous expiration and continues to the residual volume. The physiotherapist through the cough provoked or stimulation of the trachea gets expectoration of sputum, to be able to assess its weight.
The protocol in the high frequency compression chest wall group consists of the same protocol as the respiratory physiotherapy Group plus high frequency compression chest wall applied with Smart Vest® device, with a fixed frequency of 13 Hz and a time 15 min. The selected mode will be the normal (fixed parameters) and the pressure of 4 units (12 cm H2O). The patient remains seated on his parents, and with a cotton garment between the vest and the skin of the patient to prevent skin lesions.
Attention must be paid during maneuvers to maintain a position of infant in supine decubitus in 30 degrees of slope, to avoid episodes of gastroesophageal reflux and decrease the risk of vomiting.
Criteria for cessation of physiotherapeutic intervention, alterations will be considered abrupt of the respiratory rhythm (brady or tachypnea), stare, ocular revulsion, hiccups or hypertonia and changes in skin color (pallor or cyanosis). In addition to these manifestations clinics, it is established that if the parent or legal guardian so requires, the the application of the protocol.
After 10 and 20 minutes of finishing both groups, the doctor again makes a measurement of mucus volume, SO2, heart and respiratory rate, and classify again according to the criteria of Wang's clinical severity scale.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Manual maneuvers physiotherapy
The protocol of physiotherapy treatment techniques consists of 20 minutes of FR based on prolonged slow expiration and cough provoked.
|
20 minutes of manual maneuvers physiotherapy based on prolonged slow expiration: passive technique of expiratory help applied to the baby through a slow thoracic-abdominal pressure that begins at the end of spontaneous expiration and continues to the residual volume.
The physiotherapist through the cough provoked or stimulation of the trachea gets expectoration of sputum, to be able to assess its weight.
|
Experimental: High frequency compression chest wall
The protocol consists in the application of the Smart Vest® device for high frequency compression of the chest wall, with a fixed frequency of 13 Hz and a time of 15 minutes.
Then during 20 minutes will apply the same protocol as in the manual maneuvers group.
