Electrical stability of the heart during hypothermia-induced potassium plasmatic level changes and after modulation of the autonomic nervous system by renal denervation.
Kudlička, Jaroslav ; Kittnar, Otomar (advisor) ; Nováková, Marie (referee) ; Danzig, Vilém (referee)
Malignant ventricular arrhythmias are a common cause of sudden cardiac death. Moderate therapeutic hypothermia (MTH) is routinely used in post-resuscitation care for anticipated neuroprotective effects. However, the safety of MTH in terms of the electrical stability of the heart has not been satisfactorily proved yet. Also, the increased sympathetic tone in patients with heart failure contributes to a higher incidence of malignant ventricular arrhythmias. The aim of this work was to verify the safety of MTH as regards the inducibility of ventricular fibrillation (VF) in the pig biomodel, especially in relation to spontaneous changes in the kalemia and QT interval. Furthermore, we assumed that renal denervation (RDN) could reduce the inducibility of VF. In the first part of the thesis, the extracorporeal cooling was introduced in fully anesthetized swine (n = 6) to provide MTH. Inducibility of VF was studied by programmed ventricular stimulation (8 basic stimuli with up to 4 extrastimuli) three times in each biomodel under the following conditions: during normothermia (NT), after reaching the core temperature 32 řC (HT) and after another 60 minutes of stable hypothermia (HT60). VF inducibility, effective ventricular refractory period (ERP), QTc interval, and potassium plasma level were measured. In...

Adult Advanced Life Support in Hospital
Jarešová, Petra ; Hošťálková, Monika (advisor) ; Burišková, Klára (referee)
The Thesis deals with the issue of provision of advanced life support in a Hospital. The main focus is the process, algorithm, of successive individual steps, its correct performance in practice should lead to the provision of effective CPR or to minimize subsequent post-resuscitation complications. The Thesis is mainly focused on non-medical health worker, as an important member of the healthcare team, his tasks, responsibilities and competences. The theoretical part will be processed according to the current guidelines of the European Resuscitation Council. Within the subsequent empirical part is included the methodology of realized research, the process of data collection, and the final interpretation of the results, followed by analysis and discussion. The survey is conducted by quantitative research, using the questionnaire survey. The aim of the research was to determine respondents' level of theoretical training, ways of continuing education and current conditions at selected workplaces. Based on detected results, the steps for nursing practice are proposed. KEY WORDS: advanced life support, sudden cardial arrest, sudden respiratory arrest, ventricular fibrillation, electrical defibrillation, algorithm of KPCR, post - resuscitation syndrome, activities of nurse.
