The physiological impact of digestive changes in geriatric patients and their impact on dietary and fluid intake
Krotilová, Martina ; Maruna, Pavel (advisor) ; Živný, Jan (referee)
Introduction: This bachelor thesis focuses on the aging process, physiological changes in the digestive tract, and the potential severe problems associated with advanced age that may impact diet and fluid intake. In the theoretical part, it summarizes the most important factors discussing old age and its related aspects. The practical part compares the theoretical research with the collected results from a questionnaire survey and laboratory blood tests. Aims: The main general aim of this thesis was to conduct a search of literature and scientific studies, and then to compare these findings with the data collected in the practical part. It was necessary to obtain the specific changes in the given sections of the digestive tract from the literature and research. The practical part included a questionnaire survey and the results of laboratory blood tests of geriatric patients to compare the diet of current versus younger age and, if necessary, to find out the reasons for the change. Methods: The quantitative questionnaire survey was realized between December 2022 and February 2023 in the Home for the Elderly, Prague 4 Háje and was completely anonymous. The target group were individuals from the elderly population. The questionnaire was based on a professional article by Professor Hana Kubesova. The...

The meaning of hydratation old people from the perspective of nurses
GRIMM, Viktor
The aim of the bachelor work is to fulfill the following: 1. to research the nurses´knowledge of seniors´ hydratation, 2. to research the nurses´procedure of monitoring the seniors´hydratation and 3. to research the nurses´role in seniors´care concerning hydratation. To achieve the aims mentioned there have been seven research questions to be answered: What is the nurses´ knowledge in the field of hydratation?, How do nurses keep their knowledge and how do they extend it? Are there any significant differences as for maintaining and upgrading knowledge regarding hydratation among nurses of individual units? What are the hydratation signs nurses monitor and evaluate? Are there any differences as for the seniors´hydration procedures among nurses of individual units? What interventions concerning seniors´ hydratation care do nurses carry out? And How do nurses perceive their part of care connected with seniors´liquid intake? To get valuable information for the empiric part of the work there has been carried out a qualitative research method for which a semi-structured dialogue has been used.This dialogue included 22 open questions which were completed by follow-up questions if necessary, see the attachment 1.The questions were aimed at the following: what do nurses monitor while taking care of seniors in danger of hydratation, what are the key interventions the nurses carry out but also if they are being educated in this field and how important do they consider their part. The respondents were 6 general nurses who provide care for geriatric patients endangered by dehydratation. To analyse the research results the method of open coding, pencil-paper, was used. For better orientation the research results have been put into four main categories and several sub-categories. These logically created categories were set to deal with individual hydratation issues from the nurses´point of view, complexly, taking wider circumstances into consideration including nurses´education and their personal opinions on this topic.Thank to opinions of the general nurses, the most competent ones, the work´s results provide us with a complex view on the matter and that is why it can be used as the source of information not only for students, hospital attendants and nurses but also for common people who look after a senior at home and that is why they are highly interested in this issue.

Mathematical analysis of models arising in continuum mechanics with implicitly given rheology and boundary conditions
Maringová, Erika ; Bulíček, Miroslav (advisor)
In the thesis, we study the Navier-Stokes-like and the Navier-Stokes-Fourier- like problems for the flows of homogeneous incompressible fluids. In the first part of the thesis, we introduce a new type of boundary condition for the shear stress tensor, which includes the time derivative of the velocity. Therefore, we are able to capture the dynamic response of the fluid on the boundary. As the second part of the thesis, we include the published journal article co-authored by J. Žabenský on the Navier-Stokes-Fourier-like problem formulated in the complete thermodynamic setting. In both parts, the constitutive relations are formulated implicitly with the use of maximal monotone graphs. The main result of the thesis is the existence analysis for the above mentioned problems.

Fluid resuscitation and haemotherapy in the intensive care from the perspective of nurse
NĚMCOVÁ, Kateřina
This thesis focuses on the fluid replacement therapies and the use of blood products in intensive care which is part of the daily routine for the mutidisciplinary team on intensive care including the intensive care nursing staff. These therapies span wide array of functions, including but not limited to fluid status management, electrolyte replacement and optimisation, therapeutic purposes and the delivery of nutritional requirements. The administration of blood products is vital in modern day medicine, partyicularly in the intensive care setting, and although there has been significant improvements in the standard of safety it is not completely without risk. The role of the intensive care nurse is vital not only in the preparation and administraton of blood products but also to watch for potential complications and side effects that may arise. They are also responsible for meticulous care of venous access ports as these are frequently used in the intensive care setting and must be well looked after to ensure patency and to prevent infection. This thesis is divided into parts in an attempt to cover the main issues surrounding fluid managemnet and the administration of blood products. The first part aims to summarise the relevant physiology underlying fluid balance, transfusion medicine and homeostasis. Next, based on reviewing the current literature, we aim to describe the current terminology approaches to fluid management and summarise the most commonly used products. The following sections are written with a focus on nursing care the tasks involved and their responsibilities and an overview of the possible complications that may arise with fluid replacement strategies. The important aspects of transfusion medicine are described by first defining the available blood products commonly used on intensive care followed by the basic principles underpinning the indications for their usage. We go on further to highlight the possible complications of these respective therapies and what nursing staff should be vigilant for when involved in the care of patients receiving blood products. We also address the role of the nurse in the care of the patient in hypovolemic shock. This encompasses the principles and therapies previously described in an acute setting. We describe the principles of management of such patients together with the clinical implications and practical considerations that need to be taken into account. We also focus on the particular responsibilities of the nurse in the care of such patients on intensive care. At the end of this thesis we summarised the safe concept of intravenous therapy. The second aim of this paper was based on the literature search to summarise and compare modern trends in fluid management.

Keeping of drinking habits in hospices in case of walking patients
MATOUŠEK, Jan
This diploma thesis deals with the problem of the drinking-regime keeping in case of patients in hospices and in case of seniors living on their own. The phrase 'drinking regime' means correct fluid supplement which is necessary for a human body. It is the main way to recover the daily fluid loss. The intake of fluids is essential at any age, though even more essential it is at the old age, when the human body encounters considerable natural decrease in amount of fluids and what is more, when a man also loses the feeling of thirst. To stay healthy and in a good shape, it is necessary to maintain a balance between the intake and expenditure of fluids during a day. From this point of view, it is important to have a regular fluid intake during a day - especially to drink sth. before one starts to feel thirsty.
