Clinical Trial Summary

Acute chest syndrome (ACS) is a frequent complication of sickle cell disease and is diagnosed by having findings on a chest x-ray and one of the following: chest pain, fever, or trouble breathing. Patients with Acute Chest Syndrome can get very sick and require an exchange transfusion (special large blood transfusion) and mechanical ventilation. Bi-level Positive Airway Pressure (also known as BLPAP or BiPAP) is a device that blows air into a patients lungs via a mask that covers the nose. The goal of this study is to determine whether giving children BiPAP when they have ACS, in addition to providing standard clinical care for ACS, alters the clinical course of these patients. The investigators hypothesize that patients receiving effective BiPAP will have milder clinical courses resulting in shorter hospital stays and fewer transfers to the intensive care unit and exchange transfusions.


Description:

Acute chest syndrome (ACS) is a frequent complication of sickle cell disease and is diagnosed by a new infiltrate on chest x-ray and one of the following: chest pain, fever, or respiratory signs or symptoms (tachypnea, cough, new onset hypoxemia, or increased work of breathing.)The treatment for acute chest syndrome is focused on supportive care with hydration, antibiotics, blood transfusions and respiratory support. Unfortunately, despite these treatments many patients fail to have improvements in their respiratory status, or have respiratory decompensation. These patients require more aggressive treatments, which frequently include exchange transfusions, pediatric intensive care unit (PCCU) management, and respiratory support.

The study objective is to perform a prospective double blind randomized control trial to investigate if early initiation of effective BiPAP in addition to providing standard clinical care for ACS alters the clinical course of these patients vs. sham BiPAP and standard clinical care. Investigators hypothesize that participants receiving effective BiPAP will have milder clinical courses resulting in shorter hospital stays and fewer transfers to PCCU and exchange transfusions.

Outcome

Type Measure Description Time frame Safety issue
Primary Length of Stay as Measured by the Time From Initial Diagnosis of ACS Until Meeting Discharge Criteria. Length of stay as measured by the time from initial diagnosis of ACS until meeting discharge criteria. It is anticipated length of stay will correlate to efficacy of treatment: shorter stay is theorized to indicate more efficient treatment. From diagnosis of ACS until meeting discharge criteria- Average 7 days.
Secondary Rate of Exchange Transfusions. Diagnosis until discharge. Average 7 days.
Secondary Determine Parent and Patient Acceptability of BLPAP Administration in the Setting of ACS. Upon completion of intervention at 48hrs.
Secondary Rate of PCCU Transfers. Diagnosis until discharge. Average 7 days.
Secondary Difference in Respiratory Rate. 48hrs after initiation of treatment
Secondary Difference in Pulmonary Function Tests. 48hrs after initiation of treatment
Secondary Difference in Mean SpO2 Recording During Sleep. Peripheral capillary oxygen saturation (SpO2) is an estimate of the amount of oxygen in the blood. It is the percentage of haemoglobin containing oxygen compared to the total amount of haemoglobin in the blood (i.e. oxygenated haemoglobin vs oxygenated and non-oxygenated haemoglobin). 48hrs after initiation of treatment
