Interposed abdominal compression-cardiopulmonary resuscitation and resuscitation outcome during asystole and electromechanical dissociation.
BACKGROUND Coronary perfusion pressure has been shown to be a significant determinant of return of spontaneous circulation from cardiac arrest during asystole and electromechanical dissociation. The addition of interposed abdominal compression to otherwise standard cardiopulmonary resuscitation (CPR) increases coronary perfusion pressure in animal and human models. METHODS AND RESULTS Accordi...
متن کاملClinical and experimental studies on electromechanical dissociation.
Electromechanical dissociation (EMD) is the most frequent cause of unsuccessful cardiac resuscitation in critically ill patients. In a clinical study of cardiac arrest, including 54 episodes in 50 fully monitored patients, 14 episodes of ventricular fibrillation were observed and seven were reversed. In the remaining 40 instances, 36 cases of EMD were initially observed. Four patients had asyst...
متن کاملAuto-PEEP during CPR. An "occult" cause of electromechanical dissociation?
A 64-year-old man with severe COPD developed refractory nonperfusing sinus rhythm after intubation and positive-pressure ventilation. Fifteen minutes after resuscitative efforts were halted, the patient was noted to have spontaneous respirations and blood pressure, suggesting that dynamic hyperinflation was responsible for the observed electromechanical dissociation (EMD). We recommend a brief ...
متن کاملAtypical electromechanical dissociation in a patient with recurrent pulmonary embolism.
A 47-year-old man experienced recurrent pulmonary embolism resistant to aggressive medical and surgical prophylaxis. Although paraneoplastic hypercoagulability was suspected, no endoscopic or radiologic signs of malignancy were detected. Death was the result of electromechanical dissociation, which was attributed to right ventricular outflow obstruction. At autopsy, anaplastic lung carcinoma wa...
متن کاملAlternating atrial electromechanical dissociation as contributing factor for pulsus alternans.
Ten patients with mechanical pulsus alternans were studied by echocardiography and mechanocardiography. All had been or were in congestive heart failure. An atrial mechanism for pulsus alternans could be identified in two patients: one with primary congestive cardiomyopathy and one after aortic valve replacement for calcific aortic stenosis. Each strong systole was preceded by an "a" wave, whil...
