About this study

Official title: The Effect of Respiratory Exercise Using Preoperative Biofeedback on Postoperative Pain

This study is a multi-center, randomized, controlled, double-blinded, and parallel design study. A total of 106 patients were decided to be recruited considering a 10% dropout rate. Patients are randomizes to perform or not respiratory exercises using biofeedback device(ResCalm). The randomization numbers are generated using a computer-generated randomization code and are sealed in the opaque envelope until they are handed over to anesthesiologist in charge of patient management. Record patient preoperative t anxiety, postoperative pain, and pain medication use. Patient aged 19-64 yr, ASA class 1 or 2, and are scheduled for elective laparoscopic cholecystectomy are included. Patients who were unable to perform self breathing at regular intervals were excluded.

Read the detailed description
  1. Assignment of experimental groups Group A: Respiratory exercise using respiratory biofeedback device(ResCalm) is applied 2-3 times / day for 3 minutes until discharge from hospital and once in the recovery room before surgery. Group B: General surgery schedule without control exercise. All patients measure STAI(state trait anxiety inventory) at the operating room entrance on the day of surgery.
  2. anesthesia methods Intravenous anesthesia is performed using the target injection concentration control method. As an anesthetic, propofol / remifentanil / rocuronium is used. The artificial ventilation method is a pressure-controlled ventilation method, which maintains an appropriate pressure and performs anesthesia.
  3. postoperative care After anesthesia, the patient wakes up and transfers to the recovery room to encourage self-breathing exercise. After entering the recovery room, the patient's vital signs (average blood pressure, heart rate, oxygen saturation) and analgesic use are checked immediately before leaving.

The investigators check for the presence of pulmonary complications, visual analog scale (VAS), analgesic use, and hospital patient satisfaction for 24 hours after surgery.

What is being measured

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

  1. Total score of STAI(state-trait anxiety inventory)

    Preoperative anxiety state is measured using STAI(state-trait anxiety inventory): Total score of 40 questions.

    Each question is consisted as follows

    1: not at all 2: a little 3: somewhat 4: very much so minimal: 40 maximum: 160

    Measured: 20 minutes before the anesthesia started.

Secondary outcomes (3)
  1. Total amount of cumulative analgesics

    total amount of analgesics are measured for 24 hours after surgery.

    Measured: 24 hours after the anesthesia finished.

  2. The rate of Pulmonary complication

    medical record is checked after operation

    Measured: 24 hours after the anesthesia finished.

  3. The score of pain

    VAS(visual analog scale) measurement for 24 hours after surgery(0-10) 0: no pain 10: severe pain

    Measured: 24 hours after the anesthesia finished.

Questions about this trial

What is this clinical trial studying?

A study testing Respiratory biofeedback in people with Postoperative Pain, run by Seoul National University Bundang Hospital at 1 site in South Korea.

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 1 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: status not confirmed, as of the sponsor's last update on 10 Jan 2024. 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 South Korea. 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?

Total score of STAI(state-trait anxiety inventory) (time frame: 20 minutes before the anesthesia started.). 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 10 Jan 2024.
