The knowledge of critical care nurses regarding intra-aortic balloonpump counterpulsation therapy

Oosthuizen, Phillippus Johannes 01 1900 (has links)
Intra-aortic balloonpump (IABP) counterpulsation therapy is a volume displacement device designed to provide partial assistance to the left ventricle of the heart. Critical care nurses are expected to manage IABP therapy. It is therefore important that the critical care nurse has the knowledge to manage IABP therapy in a safe and therapeutic manner. The question arises: does the critical care nurse have the knowledge to manage IABP therapy? The purpose of this research study is to explore and describe the knowledge of the critical care nurse regarding the management of IABP therapy. The design of this research study is a quantitative, descriptive and contextual study, in which a sample survey was performed, using a questionnaire (based on a literature study) under controlled conditions. The knowledge of the majority of critical care nurses tested was found to be insufficient. Safe management guidelines and in-service training have been proposed to improve the situation. / lntra-aortiese ballonpomp (IABP) teenpulsasie terapie is 'n volume verplasings apparaat, antwerp om gedeeltelike ondersteuning aan die linker ventrikel van die hart te bied. Kritiekesorgverpleegkundiges is verantwoordelik vir die hantering van rASP terapie. Die vraag ontstaan: beskik die kritiekesorgverpleegkundige oor voldoende kennis rakende die hantering van IABP terapie? Die doel van hierdie studie is om die kennis van kritiekesorgverpleegkundiges te ondersoek en te beskryf rakende die hantering van IABP terapie. Die resultate van hierdie navorsingstudie dui daarop dat die meerderheid kritiekesorgverpleegkundiges wat getoets was oor onvoldoende kennis beskik ten opsigte van IABP terapie. Formulering van riglyne en indiensopleiding is aanbeveel om hierdie situasie te verbeter.

Kliniese bevoegdheid van die kritiekesorg verpleegkundige tydens die verpleging van 'n pasiënt op 'n intra-aortiese ballonpomp (IABP

De Wet, Belinda 10 September 2012 (has links)
M.Cur. / The intra-aortic balloon pump is a volume displacement device that is used to provide partial support to the left ventricle. The IABP is an effective and general used circulatory support device. The nursing of a patient on IABP therapy requires demonstration of specific clinical competence by the critical care nurse. Clinical competence is defined as the ability of the critical care nurse to integrate his/her knowledge, skills and values and to demonstrate it during nursing of a patient on IABP with the aim to promote the patient's health. The aim of this research had been to evaluate the clinical competence of the critical care nurse during the nursing of a patient on IABP, and to make recommendations according to that regarding education, the practice and research. The relationship between the components of clinical competence namely knowledge, skills and values that were set as aim, were also established. A quantitative, contextual, descriptive, correlational research design had been used in the study to compile a self-developed evaluation instrument that had been used to evaluate the clinical competence of the critical care nurse. The evaluation instrument consisted of a questionnaire that evaluated the knowledge of the critical care nurse, a check list that evaluated the skills of the critical care nurse and a semantic differential scale that evaluated the values of the critical care nurse during the nursing of a patient on IABP therapy. After the data was analyzed, it appeared that critical care nurses don't possess the necessary knowledge and skills to nurse patients on IABP, and as such are not clinically competent to nurse patients on IABP. iii Recommendations were made regarding education, the practice and research in order to improve the clinical competence of critical care nurses during the nursing of a patient on IABP therapy

PROBLEMATIKA POSKYTOVÁNÍ ÚZCE SPECIALIZOVANÉ PÉČE NEMOCNÉMU S INTRAAORTÁLNÍ BALÓNKOVOU KONTRAPULZACÍ / THE ISSUE OF PROVIDING HIGLY SPECIALIZED CARE TO PATIENT WITH INTRA-AORTIC BALLOON COUNTERPULSATION

ŠMERÁKOVÁ, Věra January 2015 (has links)
This thesis is focused on the issues linked with providing highly specialized care to critically ill patients with intra-aortic balloon pump (IABP) in intensive care units. IABP helps these patients overcome period of acute phase of heart failure or overcome period of time necessary before definitive intervention or surgical solution. A nurse has an irreplaceable role from the very beginning of patient's preparation before insertion of mechanical support (psychological as well as physical), assumes the assistance and instrumentation during insertion of heart support, observation during counterpulsation to psychological support of the patient leading to disconnection (weaning). This thesis is divided into two parts. Theoretical part is organized in several theme units focused on description and method principles, main indications, contraindications, and complications occuring with counterpulsation. The next part is dedicated to nurse's role in the problematics of saturation of bio-psycho-social needs of IABP patients. And the last part characterizes the specifics of intensive care. The core of practical part was qualitative research as per defined goals. The main objective was to map demand for quality nursing care in connection with IABP. This aim was reached through definition of four sub-aims and five research questions. The research questions were focused firstly on knowledge preconditions of nurses and problematic areas of care for IABP patients. Secondly, research effort was focused on the area of insufficient needs of patients in the bio-psycho-social area and on quality of information provided to patients. Imaginary centerpiece of research investigation consists of analysis of case studies of patiens, graphic visualisation of their thought map was used to survey the specifics of nursing care. For the evaluation of needs and mapping of patient's awareness the technique of individual half-structured interview with open questions was used. Same was used with nurses for mapping of problematic areas of nursing care. At the same time casuistry was formed as classical method of description followed by analysis of nursing case. Its meaning was to clarify optimization of means, processes and nursing interventions, i.e. mapping the specifics of nursing care of IABP patients. Research group consisted of patients selected intentionally with regards to the research problematics. For a complex conseption of the research the group for qualitative investigation consisted of four patients of cardio-surgery unit and one patient of coronary unit. Research investigation was realized in coronary intensive care units in České Budějovice hospital and Faculty hospital Plzeň and in Cardio-surgery unit of FN Plzeň. Research group for investigation of nursing problematic was formed by nurses of coronary units and cardio-surgery units of above mentioned hospitals. Eight nurses participated in the interviews. The selection of nurses was finalized only after the research topics were developed in detail. At that time sample selection was not bringing any new information any more, hence theoretical saturation of factual reality was reached. Based on analysis of research results within the goal defined and focused on the level of nurses' theoretical knowledge of nursing patients during IABP therapy it was observed that even though nurse's knowledge is sufficient, it is also significantly inconsistent. Relatively vast reserves were found especially in the area of communication with patients, hence in complex care for patient's psychological state.

Intra-aortic balloon pump (IABP) counterpulsation improves cerebral perfusion in patients with decreased left ventricular function

Pfluecke, C., Christoph, M., Kolschmann, S., Tarnowski, D., Forkmann, M., Jellinghaus, S., Poitz, D. M., Wunderlich, C., Strasser, R. H., Schoen, S., Ibrahim, K. 17 September 2019 (has links)
Background: The current goal of treatment after acute ischemic stroke is the increase of cerebral blood flow (CBF) in ischemic brain tissue. Intra-aortic balloon pump (IABP) counterpulsation in the setting of cardiogenic shock is able to reduce left ventricular afterload and increase coronary blood flow. The effects of an IABP on CBF have not been sufficiently examined. We hypothesize that the use of an IABP especially enhances cerebral blood flow in patients with pre-existing heart failure. Methods: In this pilot study, 36 subjects were examined to investigate the effect of an IABP on middle cerebral artery (MCA) transcranial Doppler (TCD) flow velocity change and relative CBF augmentation by determining velocity time integral changes (ΔVTI) in a constant caliber of the MCA compared to a baseline measurement without an IABP. Subjects were divided into two groups according to their left ventricular ejection fraction (LVEF): Group 1 LVEF >30% and Group 2 LVEF ≤30%. Results: Both groups showed an increase in CBF using an IABP. Patients with a LVEF ≤30% showed a significantly higher increase of ΔVTI in the MCA under IABP augmentation compared to patients with a LVEF >30% (20.9% ± 3.9% Group 2 vs.10.5% ± 2.2% Group 1, p<0,05). The mean arterial pressure (MAP) increased only marginally in both groups under IABP augmentation. Conclusions: IABP improves cerebral blood flow, particularly in patients with pre-existing heart failure and highly impaired LVEF. Hence, an IABP might be a treatment option to improve cerebral perfusion in selected patients with cerebral misperfusion and simultaneously existing severe heart failure.
