a strategy employing moderate hypothermia for the replacement of the aortic arch is proposed to avoid the complications of profound hypothermic circulatory arrest. two patients underwent the complete replacement of the aortic arch using three pumps - for the brain, thoracoabdominal aorta, and heart, respectively. there were no complications and the patients were extubated uneventfully. the meth...

The mean of the term “cardioplegia” is “lesion, attack, wound or blow”, very different to how its is most commonly understood in most heart centers, where it relates to cardiac protection. Thus, “cardioplegic solution” is better defined as a solution capable of inducing cardiac arrest. Cardiac arrest induced by cardioplegic solutions can occur by hyperpolarizaton, depolarization or by inhibitin...

Normothermic ischemic arrest of the heart as an adjunct to open-heart surgery has gained widespread clinical acceptance. This form of arrest, achieved by simply cross-clamping the ascending aorta to eliminate coronary perfusion, is convenient in that it provides a bloodless operative field and a relaxed myocardium. The upper limit ofthe safe period of such ischemia is generally considered to be...

Der European Resuscitation Council (ERC) hat diese Leitlinien für lebensrettende Systeme basierend auf dem 2020 „International Consensus on Cardiopulmonary Science with Treatment Recommendations“ erstellt. Behandelt werden folgende Themen: die Überlebenskette, Messung der Reanimationsleistung, Social-Media- und Smartphone-Apps zur Einbindung Bevölkerung, „European Restart a Heart Day“, „World H...

The authors analysed a series of 557 consecutive patients who suffered cardiorespiratory arrest at the Dante Pazzanese Institute of Cardiology (DPIC) during a period of 5 years in order to examine factors predicting successful resuscitation and long-term survival. Cardiopulmonary resuscitation (CPR) maneuvers were tried in 536 patients, with the following results: 284 patients (53%) died immedi...

Curves relating left ventricular end-diastolic pressure (LVEDP) to echocardiographically determined end-diastolic diameter (LVEDD) were obtained before and after ischemic arrest in 15 patients during open heart surgery. LVEDP ranged from 0-20 mm Hg during routine operation of the heart-lung machine. Ischemic arrest ranged from 0-94 minutes. In eight patients averaging 21 ± 7 (SEM) minutes of ar...

background:  patients undergoing cemented hip hemiarthroplasty may develop bone cement implantation syndrome (bcis) which is a leading cause of intraoperative complications. the purpose of this study was to evaluate cardiovascular changes during cemented hip hemiarthroplasty in elderly patients.   methods:  cemented hip hemiarthroplasty was performed on 72 patients with femoral neck fracture. a...

Cardiac arrest caused by startling stimuli, such as visual and vibration stimuli, has been reported in some animals and could be considered as an extraordinary case of bradycardia and defined as reversible missed heart beats. Variability of the heart rate is established as a balance between an autonomic system, namely cholinergic vagus inhibition, and excitatory adrenergic stimulation of neural...
