Postoperative Pulmonary Complications In Obstructive Sleep Apnea Patients

September 15, 2023 updated by: Demet Laflı Tunay, Cukurova University

Predicting Postoperative Pulmonary Complications In Obstructive Sleep Apnea Patients; Multicentre, Prospective, Observational Cohort Study

It is known that perioperative respiratory complications occur more often in obstructive sleep apnea syndrome (OSAS) patients during general anesthesia. Although there are prospective RCTs in this area, the need for further and larger studies remains due to the heterogenity of the results. Moreover, the incidence of postoperative pulmonary complications in OSAS patients undergoing surgery in Turkey and the predictive factors affecting the respiratory adverse events are uncertain. Therefore, in this prospective observational cohort study, it was aimed to determine the incidence of postoperative pulmonary complications and the predictor factors associated with patient, anesthesia and surgery in surgical patients with a confirmed or highly suspected OSAS diagnosis undergoing general anesthesia.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Not yet recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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

  • Adult

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
OSAS patients with postoperative pulmonary complication
American Society of Anesthesiologists (ASA) physical status I-III adult patients age between 18-65 years undergoing elective surgery with general anesthesia and diagnosis of OSAS will be recruited in this study. In this patient group, the incidence of postoperative early-period and long-term pulmonary complications will be investigated.
Procedure: Elective surgical procedure under general anesthesia
The incidence of postoperative pulmonary complications in OSAS patients undergoing elective surgery under general anesthesia will be determined.

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
postoperative pulmonary complications
Time Frame: Postoperative day 1, 2, 7 and 30.
The rate of postoperative hypoxia (respiratory failure), atelectasis, pulmonary edema /embolus, aspiration, bronchospasm, respiratory infection / pneumonia, pleural effusion, pneumothorax, respiratory arrest will be measured
Postoperative day 1, 2, 7 and 30.

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.
Outcome Measure
Measure Description
Time Frame
Predictive factors
Time Frame: Postoperative day 1, 2, 7 and 30.
Determination of patient, anesthesia and surgery-related predictive factors affecting the development of postoperative pulmonary complications.
