About this study
Official title: Acute Effects of BIPAP vs CPAP on Hemodynamics and Respiratory Parameters in Management of Type 2 Respiratory Failure Patients
Effectiveness of BIPAP is evaluated in Type-2 failure but evaluation of effectiveness of CPAP in Type-2 respiratory failure in post cardiac surgery patients was not done. So the objective of this study is to determine the acute effects of BIPAP vs. CPAP with conventional physiotherapy on Hemodynamics and Respiratory parameters in management of Type 2 Respiratory failure in post cardiac surgery patients.
Read the detailed description
Non-invasive ventilation (NIV) refers to the provision of Ventilatory support through the patient's upper airway using a mask or similar device. This technique is distinguished from those which bypass the upper airway with a tracheal tube, laryngeal mask, or tracheotomy and are therefore considered invasive. NIV refers to non-invasive positive pressure ventilation, Continuous positive airway pressure (CPAP) refers to the non-invasive application of positive airway pressure, again using a face or nasal mask rather than in conjunction with invasive techniques.
A study on Non-invasive ventilation in postoperative patients was conducted in 2017 in Italy; systematic review was performed on Patients undergoing any of the following procedures, thoracic surgery, lung surgery, abdominal surgery, solid organ transplantation, thoraco-abdominal surgery and bariatric surgery were included. Information on demographics, medical history, preoperative medications, postoperative care Pharmacologic management and laboratory investigation results were obtained from medical charts.
Prospective, randomized, case-controlled, pilot study included forty patients, who underwent elective (OPCAB) and were randomized into two groups. group-A (BiPAP) and group-B . All patients received same regimen of medication. Group-B was kept on BiPAP immediately following extubation, while, group-B received conventional physiotherapy only. All hemodynamic and oxygenation parameter were recorded and chest radiographs were done to find out incidence of atelectasis. Patients were followed up to their discharge.
Noninvasive Ventilatory support does not facilitate recovery from acute respiratory failure in chronic obstructive pulmonary disease his investigation evaluates, in a prospective, randomized and controlled manner, whether noninvasive ventilatory support (NIVS) with bilevel positive airway pressure (BiPAP) facilitates recovery from acute respiratory failure (ARF) in patients with chronic obstructive pulmonary disease.
Effects of Positive Airway Pressure in Patients with Heart Failure and Obstructive Sleep Apnea done at Toronto General Hospital University Health Network and Mount Sinai Hospital Twenty-four patients with a depressed left ventricular ejection fraction (45 percent or less) and obstructive sleep apnea who were receiving optimal medical treatment for heart failure underwent polysomnography. The subjects were then randomly assigned to receive medical therapy either alone (12 patients) or with the addition of continuous positive airway pressure (12 patients) for one month. The assessment protocol was then repeated.
Bilevel positive airway pressure on ventricular ectopy in heart failure patients with obstructive sleep apnoea was done at canada in 2015. Following optimisation of medical treatment and cpap.The frequency of vpbs and urinary norepinephrine (noradrenaline) concentrations during total sleep time were determined at baseline and after 1 month

Secondary outcomes (2)
Richmond Agitation-Sedation Scale (RASS)
Richmond Agitation-Sedation Scale is a medical scale used to assess the agitation or sedation level of a individual. Changes from the Baseline. Below 0 means drowsy and sedated, 0 means alert and calm and 1 or above 1 means restless \& agitated
Measured: 3rd day
Confusion Assessment Method for the Intensive Care Unit (CAM-ICU)
Changes from the baseline. It will provide a qualitative result of "delirium present" or "delirium absent". Clinical psychologist delirium is defined in terms of four diagnostic features, and is deemed present when a patient has positive Feature 1 and Feature 2 and either Feature 3 or 4. overall answer in Yes or No

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Effectiveness of BIPAP is evaluated in Type-2 failure but evaluation of effectiveness of CPAP in Type-2 respiratory failure in post cardiac surgery patients was not done. So the objective of this study is to determine the acute effects of BIPAP vs. CPAP with conventional physiotherapy on Hemodynamics and Respiratory parameters in management of Type 2 Respiratory failure in post cardiac surgery patients.

Questions about this trial
What is this clinical trial studying?
A study testing BiPAP Group and CPAP Group in people with Type 2 Respiratory Failure, run by Riphah International University at 1 site in Pakistan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 16 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Pakistan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Arterial blood gas (ABG) parameter like potential of hydrogen (PH) (time frame: 3rd Day). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04020627, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
