Abstract P42: Active Compression Decompression-CPR in an Infant Manikin Model Using a Novel Adhesive Glove Device

Introduction: In animals Active Compression-Decompression(ACD)-CPR improves hemodynamics compared with standard CPR (S-CPR). We evaluated the feasibility of achieving ACD-CPR with a novel, simple and inexpensive Adhesive Glove Device (AGD) in an infant manikin model using two thumb (TT) chest compression. Hypothesis: AGD-ACD CPR provides better chest decompression compared to S-CPR in an infant manikin model without excessive rescuer fatigue. Methods: Laerdal ™ Baby ALS Trainer manikin was modified to digitally record compression pressure (CP), compression depth (CD) and decompression depth (DD). The thumb portion of two oven mitts were sewn together and a Velcro adhesive patch was stitched on the underside with an encircling adjustable strap for proper fit to create the AGD. An interlocking Velcro patch was glued to the manikin chest wall. Sixteen BLS or PALS certified healthcare providers were prospectively randomized to perform either two-thumb S-CPR or AGD-ACD-CPR for 5 minutes with a 30:2 compression:ventilation ratio using a crossover design. During AGD-ACD-CPR subjects were asked to pull up during chest decompression. Rescuer heart rate (HR), respiratory rate (RR), recovery time (RT) for HR/RR to return to baseline and actual compressions delivered per minute were recorded. Subjects were blinded to data recordings. Data (mean±SEM) was analyzed using 2 sided paired t-test; p-value ≤0.05 was considered significant. Results: Chest decompression was greater with AGD-ACD-CPR; the mean DD difference was 0.11±0.02 inches, p= Conclusions: Active decompression and improved recoil was achievable with the use of our simple, inexpensive AGD in this infant CPR model. Use of our device did not result in excessive rescuer fatigue compared to S-CPR. The clinical significance of 6 less compressions/minute in the AGD-CPR group needs to be determined.
