Bi-Level Positive Airway Ventilation for Acute Chest Syndrome

November 19, 2018 updated by: Deepa Manwani, Albert Einstein College of Medicine

Early Bi-Level Positive Airway Pressure (BiPAP) Ventilation for Acute Chest Syndrome (ACS) - a Double-Blind Randomized Controlled Pilot Study

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.

Detailed 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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

4 years to 21 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Must meet clinical criteria for ACS- an infiltrate on Chest X-ray and one of the following:

  • Respiratory symptoms/signs (patients pulse oximetry < 92% or oxygen saturation < 2% below their baseline, tachypnea, cough, and increased work of breathing)
  • Fever
  • Chest pain AND

Patients' eligible for a simple transfusion based on one of the following criteria:

  • Hypoxemia (patients pulse oximetry < 92% or oxygen saturation < 2% below their baseline)
  • Hemoglobin < 5 gm/dl
  • Increased work of breathing

Exclusion Criteria:

  • Patient requires exchange transfusion within first 24 hours of admission
  • Patient requires PCCU transfer within first 24 hours of admission
  • Hemoglobin > 9gm/dl secondary to these patients requiring an exchange transfusion

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Length of Stay as Measured by the Time From Initial Diagnosis of ACS Until Meeting Discharge Criteria.
Time Frame: From diagnosis of ACS until meeting discharge criteria- Average 7 days.
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 Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
