About this study
Official title: Effectiveness of Weighted Blankets to Decrease Emergence Agitation, Sedation, and Vascular Complications in a Pediatric Cardiac Post Anesthesia Care Unit Following Cardiac Catheterization
This study is being conducted to evaluate the safety and efficacy of weighted blankets to reduce agitation in patients in the post-procedural phase after cardiac catheterization and electrophysiology procedures in the post anesthesia care unit.
The study hypothesizes that compared to the traditional and current post-procedural strategy, weighted blanket use will reduce agitation and therefore lessen the need for additional sedation along with a reduction of post-procedure vascular complications.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Standard of CareOther
Following the participants procedure, standard of care will be given in the recovery area.
Weighted blanketDevice
Following the participants procedure once in the recovery area, the nursing staff will place a weighted blanket on the participants. Different weighted blanket sizes will be used based on participants weight.
| Study group | Role | What they receive |
|---|---|---|
| Standard of Care | Active comparator | Not described Receives: Other: Standard of Care |
| Weighted blanket | Experimental | Not described Receives: Device: Weighted blanket |
What is being measured
The primary outcome is the main question the study is designed to answer.
Average Richmond Agitation Sedation Scale (RASS) compared between the two groups
Richmond Agitation Sedation Score is a validated and standardized scoring system ranging from negative 5 (unarousable sedation) to 0 (awake and calm) to 4 (combative).
Measured: up to 60 minutes (after arrived to PACU)
Secondary outcomes (5)
Analgesia administered in the recovery area
Number of medications (Midazolam, Ketamine, Propofol, Dexmedetomidine, Lorazepam, etc.) required during the recovery period following the procedure.
Measured: up to 6 hours after arriving in the PACU
Incidence of vascular complications in the recovery area
This will include participants that have episodes of re-bleeding and hematomas.
Measured: up to 6 hours after arriving in the PACU
Safety measures assessed by vital sign parameters for absolute oxygen (O2 saturation)
Absolute oxygen (O2) saturation drop of 10 points or more from recovery area arrival baseline.
Measured: up to 6 hours after arriving in the PACU
Safety measures assessed by vital sign parameters for respiration rate
Respiration rate decreased 20% or more from recovery arrival baseline.
Measured: up to 6 hours after arriving in the PACU
Safety measures assessed by vital sign parameters for respiratory effort
Increased Respiratory Effort (retractions, labored, nasal flaring, etc.) as compared to recover area arrival baseline
Measured: up to 6 hours after arriving in the PACU

What does the primary outcome measure?
Average Richmond Agitation Sedation Scale (RASS) compared between the two groups (time frame: up to 60 minutes (after arrived to PACU)). 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.
