Cardiac arrest & resuscitation
Hemodynamic effects of TEE–guided adjustment of the area of the maximal compressions during cardiopulmonary resuscitation
Authors' conclusion
In patients undergoing AMC adjustment, significant improvements in SV and EF were observed, reaching levels comparable to those without adjustment.
Study context
- Population
- Adults with non-traumatic out-of-hospital cardiac arrest (OHCA)
- Participants
- 19 adults
- Exposure
- AMC-LV vs area of maximal compression (AMC)-non-LV
- AMC-LVn = 4reference
- AMC-non-LVn = 15
- Outcome
- LV parameters and EtCO2 before vs after AMC adjustment (AMC-non-LV)
Methodological detailsprospective enrolment
- Prospective enrolment
Main finding
As reported in the abstract
- AMC located over the left ventricular (LV) in 4 patients (21%); 15 (79%) required TEE-guided AMC adjustment
- Post-adjustment values comparable to the AMC-LV group
- AMC-non-LV post-adjustment vs AMC-non-LV pre-adjustment: P = 0.004
- AMC-non-LV post-adjustment vs AMC-non-LV pre-adjustment: P < 0.0001
- AMC-non-LV post-adjustment vs AMC-non-LV pre-adjustment: P < 0.0001
