Registered outcomes 6
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | State Anxiety Level | Baseline (pre-procedure) and immediately after the 4-7-8 breathing technique | Measured using the State-Trait Anxiety Inventory (STAI-S). The score ranges from 20 to 80, with higher scores indicating higher levels of anxiety. The outcome will be reported as the change in anxiety scores from baseline to immediately after the 4-7-8 breathing technique. | ClinicalTrials.gov |
| Primary | Pain | Baseline (pre-procedure) and immediately after the CVC insertion procedure. | Measured using the Visual Analog Scale (VAS), where scores range from 0 (no pain) to 10 (worst possible pain). The outcome will be reported as the change in pain scores from baseline to immediately after the CVC insertion procedure. | ClinicalTrials.gov |
| Secondary | Systolic Blood Pressure | Baseline (pre-procedure) and immediately after the 4-7-8 breathing technique. | Measured using a standardized non-invasive blood pressure monitor. The outcome will be reported as the change in systolic blood pressure from baseline to immediately after the 4-7-8 breathing technique. | ClinicalTrials.gov |
| Secondary | Diastolic Blood Pressure | Baseline (pre-procedure) and immediately after the 4-7-8 breathing technique. | Measured in mmHg using a standardized non-invasive blood pressure monitor. The outcome will be reported as the change in diastolic blood pressure from baseline to immediately after the 4-7-8 breathing technique. | ClinicalTrials.gov |
| Secondary | Heart Rate | Baseline (pre-procedure) and immediately after the 4-7-8 breathing technique. The outcome will be reported as the change in heart rate from baseline to immediately after the 4-7-8 breathing technique. | Measured as beats per minute. | ClinicalTrials.gov |
| Secondary | Respiratory Rate | Baseline (pre-procedure) and immediately after the 4-7-8 breathing technique. | Measured as breaths per minute. The outcome will be reported as the change in respiratory rate from baseline to immediately after the 4-7-8 breathing technique. | ClinicalTrials.gov |
