Trial summary

Pulmonary hypertension (PHT) is an oPAP ≥25 mmHg as assessed by right heart catheterization at rest. It is divided into 5 groups according to its etiology and mechanism. The first group is patients with pulmonary arterial hypertension due to various reasons (drugs, connective tissue diseases, etc.). Read more about this study

About this study

Official title: The Relationship of Postoperative Morbidity / Mortality Rates of Patients With Pulmonary Hypertension With Risk Factors

Pulmonary hypertension (PHT) is an oPAP ≥25 mmHg as assessed by right heart catheterization at rest. It is divided into 5 groups according to its etiology and mechanism. The first group is patients with pulmonary arterial hypertension due to various reasons (drugs, connective tissue diseases, etc.). Group 2 is classified as left heart failure, group 3 is due to chronic lung disease and hypoxemia, group 4 is due to pulmonary arterial obstruction (most commonly CTEPH), and group 5 is patients with pulmonary hypertension due to multifactorial unspecified causes.

In the pathophysiology, pulmonary hypertension occurs when the balance is disturbed by endothelial dysfunction, decrease in vasodilator mediators (NO, prostacyclin) and increase in vasoconstrictor mediators (endothelin-1, serotonin, thromboxan) in the vascular bed.

Perioperatively, patients with WHO functional classification >2, right ventricular hypertrophy, obese, chronic renal failure, previous PTE, COPD, diabetes mellitus are more prone to complications related to pulmonary hypertension. Although factors such as emergency surgery, intraoperative vasopressor use, delayed intubation, acidosis, and hyperthermia pave the way for postoperative pulmonary complications, attention should be paid to mortality and morbidity since they are also preventable factors.

Postoperatively, as a result of the supine position triggering bronchospasm with secretions, acute lung injury in addition to the existing comorbidity occurs. With the increase in respiratory workload, acute respiratory failure develops with symptoms such as hypoxemia and hypercarbia. Residual anesthesia, increased pain or prolonged mechanical ventilation time also decrease functional residual capacity, increasing the possibility of atelectasis development.

With the records we kept in our study, we aimed to show which complications the patients with pulmonary hypertension faced after their surgeries due to their underlying diseases and References ESC/ERC Guidelines Eurepean Heart Journal 2016; 37:67-119 Aguirre MA, et al. Advances in Anesthesia 2018;36: 201-30

Read the detailed description

Our study will be carried out by recording the patients with PHT who underwent non-cardiac and non-obstetric surgeries at Başkent University Ankara Hospital between 11/10/2021 and 11/10/2023. It was planned to select the patients participating in our study on a voluntary basis and to include only the patients who agreed to participate in the study. Informed consent will be obtained by informing the patients before the application.

Both patient groups will be evaluated in the anesthesia polyclinic in the preoperative period. Routine blood tests will be done. It was planned as a cohort study. Depending on the surgery type of the patients, GA or RA will be applied as appropriate. The drugs in the standard anesthesia method will be administered to the patients. Standard monitoring and, if necessary, other invasive monitoring methods will be applied. Echocardiography evaluations, pulmonary function tests will be planned, and control evaluations will be requested at the 3rd, 6th and 1st postoperative months.

By the team in the postoperative recovery unit, hypoventilation (falling below breath per minute), apnea (episodes longer than 10 seconds), hypoxemia (SpO2<90, nasal O2 or Room Air), tachypnea, dyspnea, arrhythmia, chest pain, tachycardia, hypotension 30 minutes in terms of symptoms such as hypertension, laryngospasm, bronchospasm, subcostal retraction. They will be followed throughout. They will be evaluated in terms of analgesia control with Numeric Pain Score.

It will be evaluated in terms of postoperative pulmonary complications (tracheal reintubation) in the recovery unit and afterwards, extubation failure, pulmonary edema, and pneumothorax at the end of the case, and records will be kept.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Comparison of postoperative morbidity/mortality

    In this study, we investigated how the risk factors of patients with pulmonary hypertension can be evaluated and how the treatment plan can be arranged to prevent postoperative complications and reduce postoperative morbidity/mortality rates. We aim to compare the postoperative morbidity/mortality rates and complication frequency of patients who were evaluated and treated preoperatively with those who did not receive treatment.

    Measured: 11/2021- 11/2023

Questions about this trial

What is this clinical trial studying?

An observational study of oPAP Should be > 25mmHg in Right Heart Catheterization at Rest and There Should be Patients Who Will Undergo Non-cardiac and Non-obstetric Surgery, run by Baskent University at 1 site in Turkey (Türkiye).

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 2 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: status not confirmed, as of the sponsor's last update on 4 Oct 2022. 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 Turkey (Türkiye). 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?

Results are not available in the source record.

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?

Comparison of postoperative morbidity/mortality (time frame: 11/2021- 11/2023). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Oct 2022.
