Nursing care by children with arthroscopy of the knee joint.
ŠESTÁKOVÁ, Růžena
With the increasing sports and physical activity pursued by young people, the spectrum of the knee joint injuries is extending. At the present time, arthroscopy represents one of the basic diagnostic and therapeutic methods in the case of the knee joint injuries. Owing to this method, the attending physician can examine the joint directly using the endoscopic instrument and they can possibly execute surgical treatment thereof as well. Thanks to development, this method can be applied in children's patients with ever increasing frequency. The joint subject to most frequent arthroscopy treatment is definitely the knee joint. The treatment is executed in the operating theatre, most often under anaesthesia and it is careful, quick and accurate. Nevertheless, the children's patient must be hospitalized, which means, in addition to the planned treatment, considerable mental stress not only for the child but for the whole family as well. The way how the child and the parents will cope with the situation depends to a great extent on the nursing personnel. Therefore it is necessary to pay increased attention to the nursing care. The theoretical part of the bachelor's thesis describes the anatomy of the knee joint, possible damage thereto and this theory is followed by the nursing care prior to and after arthroscopy, rehabilitation nursing care, satisfaction of needs, information provided to the children prior to leaving hospital. The application part of the thesis focuses on the children's patients who were hospitalized in the Dětská klinika Nemocnice České Budějovice a.s. (Children's Clinic of the Hospital of České Budějovice) and underwent arthroscopy of knee joint. The following part deals with the nurses working with these children. The thesis is based on a qualitative research and the acquired information was summarized in case reports and interviews. Three research questions were determined for the research part. The purpose of the bachelor's thesis is to discover the specifics concerning nursing care for children undergoing the knee joint arthroscopy. The discovered specifics, such as care for Redon drain, use of French crutches or motor splint, education of the children and their parents can help the nurse become aware of these specifics, not perform them automatically and achieve a higher quality of the nursing care provision. Identification thereof may help perform the right determination of nursing diagnoses, goals and interventions in the nursing process in the patient prior to and after arthroscopy of knee joint. Another goal of the thesis was to determine what negative factors are perceived by the children most frequently. The fact that we have discovered the specifics of the care and that we accentuate them may mitigate the negative factors perceived by the children as well. Among them there are fear, redressing relating to the Redon drain removal, pain. The acquired results of the bachelor's thesis were processed to have the form of a standard nursing plan, which should contribute to achieving a higher quality of the nursing care for children undergoing arthroscopy of knee joint.

Improvement of the patient?s safety in intraoperative nursing care.
LEŠTINOVÁ, Terezie
Abstract - Improvement of the patient?s safety in intraoperative nursing care Every activity brings about a certain rate of risk in contemporaneous healthcare facilities. Every nurse has to ensure patient?s safety. Successful management of this task requires a good overview of the patients to whom the care is provided, and of the risks which could endanger the patients, cause them harms or worsen their health condition. The present Bachelor?s Dissertation focused on the topic: ?Improvement of the patient?s safety in intraoperative nursing care?, follows two objectives. The first one is to map the most frequent risks of undesirable events which threaten to the patient during the intraoperative nursing care; the other one is to assess the rate of risk of undesirable events in the intraoperative nursing care. In accordance with the proposed objectives, two hypotheses were stated: H1: The most frequent risk of an undesirable event that threatens to a patient during the operative intervention is burn; and H2: Confusion of the patient?s identity in the intraoperative nursing care achieves the highest risk rate. The Dissertation was drawn up with the help of quantitative research investigation. The data collection method used was based on a survey where a questionnaire approach was applied. The questionnaire was non-standardised and included 21 items. The research dataset was formed of 54 perioperative nurses working in operating theatres of Nemocnice České Budějovice a.s. It implied from the research investigation that the most frequent undesirable events that threaten to patients during intraoperative nursing care are, from the viewpoint of perioperative nurses, allergies to medicine, to disinfection (3.47), sore galls (3,35) and early infection in the wound (2,90). Patient?s burn caused by a neutral electrode (1.98) was on the fifth place of undesirable events. The first hypothesis ?The most frequent risk of an undesirable event that threatens to a patient during the operative intervention is burn? was not confirmed. The undesirable events leading to the most serious consequences in the field of patient?s health condition include confusion of the patient?s identity (4.88), fire arising due to contacts of the coagulation instrument and alcohol disinfection (4.83) and confusion of the side to be operated on (4.80). Through the subsequent evaluation of the results of the questionnaire survey it was found out that the highest rate of risk in the intraoperative nursing care is achieved by confusion of the patient?s identity (3.90), confusion of the side to be operated on (3,85), fire arising due to contacts of the coagulation instrument and alcohol disinfection (3.84). The second hypothesis ?Confusion of the patient?s identity in the intraoperative nursing care achieves the highest risk rate?, was confirmed. The deliverable of the Dissertation is a proposal for safety mechanisms in the field of prevention of confusions of the patient?s identity and of the side to be operated on, as well as basic principles for safe application of the neutral electrode.

I devote a separate section to the victim of a crime act and his or her compensation as per the current legal regulation. The main part of the work deals with the offended party´s process rights in the criminal proceedings and divides them into rights pertaining to all offended parties and to the rights pertaining to those offended parties who are entitled to claim compensation for damage. I also focus on the institute of criminal prosecution with the offended party´s consent. The concluding section of the theoretical part deals with hne adhesion proceedings. The following part of the work presents my research whose purpose was to find whether the offended parties´ rights are sufficiently described in the legal order. I selected a qualitative research method, namely semi-structured interview. I asked selected experts six questions aubot the offended parties´process rights and thein application in practice. The conclusion of this part contains my proposals for modifications or amendments of certain process rights, which, as I believe, are missing in the current legal regulation. The work also features appendices: speciments of forms which bodls active in the criminal proceedings use in thein everyday practice.

Artificial Fertilisation, Genetics, Handicapped Children
Provazníková, Zdeňka ; Ovečka, Libor (advisor) ; Skoblík, Jiří (referee)
Auf der Grundlage durchgeführter Studien , Konsultationen und durcharbeiteter Literatur können wir davon ausgehen , dass die Anzahl behinderter Kinder nach einer künstlichen Befruchtug prozentual vergleichbar ist mit den Kindern , die nach natürlicher Befruchtung mit Behinderung geboren wurden. Leider ist es statistisch nicht möglich diese Prozentzahl eindeutig zu nennen , da weder in den Geburtshäusern noch anderswo diesbezügliche Statistiken durchgeführt werden. Wir können leider nur von den Angaben aus Kinderheimen ausgehen. Paare , die eine künstliche Befruchtung eingingen , waren nicht ausreichend informiert über alle Risiken , besonders eben über die Möglichkeit der Geburt behinderter inder nach einer künstlichen Befruchtung. Angesichts dessen , dass die künstliche Befruchtung finanziel sehr Anspruchsvoll ist , ihre Effektivität sich zwischen 20 bis 30 % bewegt , die Psyche der Paare sehr belastet wird , aber auch andere Risiken damit verbunden sind , stellt sich die Frage nach einer annehmbareren Möglichkeit , das Problem der Unfruchtbarkeit der Paare zu lösen. Immerhin existiert Unfruchtbarkeit seit dem Beginn der Menschheit. Mit der Unfruchtbarkeit hängen auch viele ethische Probleme zusammen. Gott gab den Menschen aber Recht einzugreifen und über Leben zu entscheiden , darf er gesetzte Grenzen...

Workplace violence - mobbing and bossing
Pocová, Vanda ; Beneš, Milan (referee) ; Tureckiová, Michaela (advisor)
Originating from an individual or a group of individuals and targeted against another individual, mobbing and bossing are two forms of workplace violence which can include persistent and constant attacks, rather psychological by their nature. Any employee can be the mobber, whereas the bosser is always the superior of the subject of bossing. The abuser aims to humiliate and subjugate the victim's personality, as a result of which the victim leaves the workplace - either voluntarily or by means of dismissal. The situation involves not only the abuser and the abused but also co-workers, superior and/or personnel managers. This bachelor thesis provides an insight to the origin and use of the terms Mobbing and Bossing. I have described individual phases of conflict development, behaviour of individual parties involved and impacts on victim's health. The final part looks at the existing European and Czech studies on this topic and the workplace violence prevention.
