Condutividade elétrica da solução nutritiva para o cultivo do crisântemo em vaso

Em se tratando do crisântemo de vaso, que constitui relevante contribuição à atividade de plantas ornamentais, ainda há necessidade de uma recomendação consistente sobre a condutividade elétrica (CE) da solução nutritiva para seu cultivo. Nesse sentido, realizou-se um experimento em ambiente protegido, objetivando avaliar o crescimento do crisântemo cv. Miramar cultivado em vaso, em função da CE da solução nutritiva e da lixiviação de sais do substrato. O delineamento experimental foi em blocos casualizados, com quatro repetições; os tratamentos foram distribuídos em esquema fatorial 5 x 2, referentes aos valores de CE da solução nutritiva (2,1; 2,8; 3,5; 4,2; e 4,9 dS m-1), em substrato com e sem lavagem para lixiviação dos sais. O aumento da CE inibiu o crescimento e desempenho vegetativo, mas estimulou o diâmetro da haste. A lixiviação dos sais estimulou, exceto quanto ao diâmetro da haste, o maior crescimento avaliado pelas demais variáveis fitotécnicas. A CE de 2,1 dS m-1 possibilita a produção de crisântemo dentro de padrões qualitativos de comercialização, mediante lixiviação periódica do substrato.

Infecção do trato urinário associada à sondagem vesical numa unidade de terapia intensiva

A descriptive, quantitative approach and non-participant observation study, which was aimed at analyzing the association between knowledge and practice of inclusion and maintenance of urinary catheter by nursing professionals in the occurrence of urinary tract infection, performed in the ICU of Onofre Lopes University Hospital in Natal / RN. The original sample was composed of 42 nursing staff professional, five (5) nurses and 37 nursing technicians, 27 of them were outsourced (FUNPEC and IEL fellows) and 10 servers UFRN. Data collection was performed using two instruments, the first observation procedures used in the insertion and manipulation of indwelling urinary catheter (IUC) and the second with a questionnaire that addressed the characterization data of respondents, knowledge and conduct the insertion and manipulation of the IUC. The results were tabulated in Microsoft Excel and analyzed using SPSS software, version 15.0. We found the prevalence of institutional staff members on outsourcing - IEL and FUNPEC - (64.3%) were female (69.0%), aged 21 to 35 years (59.5%) and with mid-level education (88.1%). As to knowledge, we found that the nurses had levels of good to excellent and the nursing technicians, to regulate the poor. The nurses made a mistake when choosing IUC (40.0%) and washing hands (30.0%) and technicians on hand washing (74.4%) and the contents of the tray (34.7%). In relation to the conduct of insertion of IUC, the nurses made a mistake when choosing SVD (66.7%) and washing hands (57.1%). Regarding the handling of IUC/drainage system, the technicians were wrong more about washing their hands (56.0%). Analyzing the misconduct to the categorization of knowledge, we saw that the nursing staff who had missed more had inadequate knowledge (ρ = 0.001). At the end we found the risk of a patient to acquire UTI is higher in two and a half times when there is a large number of mismatches, patient spends more time using the IUC and hospitalized in the ICU. As regards the study hypotheses, we accept the alternative hypothesis and reject the null hypothesis proposed at the start of this research, where the number of gaps in knowledge and behavior increases the incidence of urinary tract infection.

Repercussões da terapia comunitária no processo de trabalho na estratégia saúde da família: um estudo representacional

The Community Therapy (CT) is in a practice of therapeutic effect and may also be considered as a technology takes care of the therapeutic procedure group, whose purpose is to promote health, prevent illness, developed within primary care in mental health. In this study we sought to understand the social representations of health professionals who work with the Community Therapy, on use of the Family Health Strategy (FHS) in the city of Joao Pessoa. This is a field research with a qualitative view Moscovician Theory of Social Representations, held with seven professionals of the FHS, therapists of Community Health District II. The empirical data were obtained by carrying out two thematic therapies in April 2009, which were wheeled CT. It was used as a technique for analyzing the collective subject discourse, and the data presented through graphs, charts, maps, pictures and graphics and arranged in three stages: Subjects of the study, characterizing the study participants; Social Representations of Therapist Community presenting and discussing the social representations of therapists community studied on CT, and Consequences of Community Therapy at the Family Health Strategy, discussing the meanings attributed by the study participants about changes in FHS. Meanings were attributed to the CT by the therapists studied originated from the speeches, songs, drawings and constructed, and that presented by schematic illustration show the relation between the representations: life, listening, faith / light, change, transformation. The web, symbol of CT, appeared on the images constructed by the representatives of the study and represents the formation of bonds that allows the construction of social support networks that strengthen relationships among community. In the study, proved by professionals who have the meanings about the changes in the work process from the introduction of CT, and shown that the change took place within a more welcoming attitude on the part of professionals, the relationship between Team members had no significant changes, explained by the low compliance of team members to the CT in relation to the user front, the bond was strengthened, and this involved strengthening the role of the therapist community. It is recognized, thereby transforming the character of CT in building links with users, requiring, however, that the team is viewed as offering therapeutic services, not the professional therapist. Therefore, the CT for being a new phenomenon in health services and community belonging, it fits like a novelty which affects the construction of a representation dispute. Still, can contribute to the reorganization of mental health care in line with the new model of mental health care advocated by the Psychiatric Reform.

Custo-efetividade da terapia compressiva no processo de cicatrização de úlceras venosas

Analytical study of therapeutic nonrandomized intervention type, intra-group controlled, with the aim of analyzing the cost-effectiveness of compression therapy with manipulated Unna boot in relation to conventional therapy in the healing of venous ulcers (VU) of patients treated in ambulatory clinic. The study population was composed by patients with VU treated by angiologists in Surgical Clinic Ambulatory of the Onofre Lopes University Hospital (HUOL) with a sample of 18 patients. It obtained the assent of the HUOL Ethics in Research Committee (Protocol 276/09). Data collection was performed over a period of four months by the own master's student and 34 nursing students, through the application of the research instrument in the admission of patients to the study and in the ten subsequent evaluations, performed at the time of changing Unna boot, weekly, for a maximum period of 10 weeks. The data were analyzed with SPSS 15.0 software, using descriptive and inferential statistics, and presented as tables, charts and graphs. Among those surveyed, prevailed: females, mean age 57.6 years, low education and income levels, most retired, unemployed or off work, with the standing position more than six hours per day and up to eight hours daily of domestic or occupational activities. In health status profile of respondents there were predominantly sleep, rest and inadequate elevation of the lower limbs, no smoking and/or alcohol use, presence of hypertension and no use of drugs. Most presented the first VU for over 10 years, recurrences, present VU for more than five years, involvement of left leg, in malleolar and / or distal leg region, mild edema, hyperpigmentation, lipodermatosclerosis, telangiectasies, reticular and varicose veins, mild pain, serous exudate in moderate quantity, small lesions (up to 50cm2), with predominance of granulation tissue and / or epithelialization and demarcated, elevated and irregular borders, with crusts and macerated. Most patients reported that in the 10 weeks prior to admission, made bandages at home and / or Basic Health Unit and / or ambulatory, with nursing aides or technicians, daily, and on weekends or holidays, performed by patients themselves, using healing ointment on the lesion, being observed granulation / epithelialization and increase in VU prevalent in the 10 weeks of traditional treatment. After follow up with manipulated Unna boot, was observed a decrease of lesions in all study patients, with complete healing in 27.8% of those between 1 and 5 weeks of treatment, with satisfactory evolution of the lesions, pain and ankle and calf circumferences, and unsatisfactory development of the borders of ulcers, edema, sleep, rest and elevation of the lower limbs, especially in more chronic patients. Furthermore, patients who achieved total healing and exhibited the greatest percentage reduction of lesions had a higher number of wound healing factors (ρ = 0.01 and ρ = 0.027, respectively). The manipulated Unna boot showed better results in those patients with shorter duration of injury, leading them to a satisfactory outcome within a short period of treatment. After the cost-effectiveness analysis, we conclude that the manipulated Unna boot is more effective than conventional therapy in the healing process of VU and is more cost-effective in patients with shorter lesions (ρ = 0.001), shorter treatment (ρ = 0.000) and greater number of wound healing factors (ρ = 0.005).

Acidentes de Trabalho : análise em profissionais de enfermagem que atuam nas unidades de terapia intensiva e urgência Natal/RN

It is a descriptive-exploratory research, with a quantitative approach, aiming to characterize typical occupational accident suffered by the professionals from nursery group, in the Intensive Care Units and Emergency in a hospital in Natal-RN, trying to identify the factors that contribute to those accidents; to identify some information taken by those professionals related to the accident risks; to know the procedures taken after each accident. This sample is composed by 176 professionals that are 44 nurses and 132 nursing technicians/auxiliaries, collected from March to April 2010. The results related to the personal characterization of the nursery group showed that 31 (18.61%) are between the 36-40 years of age; 148 (84.09%) females and 96 (55.68%) had finished High School. Related to the professional characterization, 53 (30.11%) are nurses, and 123 (69.88%) nursing technicians and auxiliaries; 44 (25.00%) are working as nurses, and 132 (75.00%) as nursing technicians and auxiliaries; 45 (25.56%) are working in the nursery area between 15 to 20 years and 11 months; 53 (30.11%) are in this institution between 10 to 14 years and 11 months; 79 (44.88%) work in the ICU; 55 (31.25%) are working in this area from 1 to 4 years and 11 months; 110 (62.50%) like to work in this area; 161 (91.47%) work 30 to 40 hours per week; 90 (51,13%) have another employment. Related to knowledge about typical occupational accident, 167 (94.88%) said they know about it; 96 (54.54%) know the accident rules; 103 (58.52%) think it is important to talk about this subject in the nursery courses; 92 (52.27%) said this subject is important to be discussed in the work and 372 (87.73%) think education is necessary to reduce accident. Related to the data about accidents, 104 (59.09%) have suffered typical occupational accident, among them 69 (39.20%) have suffered it once; 47 (36.19%) did not register any accident; 60 (57.69%) were caring some patient during the accident; 47 (45.19%) of them occurred in the ICU; 50 (48.07%) professionals were working during the night period; 69 (66.34%) have suffered perforation; 86 (82.69%) had upper limbs affected; 64 (61.53%) were affected by needle; about the reason of the accident, 89 (60.54%) said it occurred due to carelessness. Related to the accident evolution, 88 (85.57%) did not need to remain off work after accident; 13 (81.25%) remained off work during 15 days; 87 (83.65%) had no sequelae and for 101 (97.11%) it was not necessary rehabilitation. We conclude that typical occupational accident can occur with young workers who admit a knowledge about the subject, however they do almost nothing to prevent it. We believe this research has contributed to the characterization of this kind of accident suffered by the nursery group of a public hospital in Natal, and it can stimulate the creation and reformulation of personal protection against typical occupational accident suffered by nursery professionals

O processo de cuidar em Unidade de Terapia Intensiva

The environment of Intensive Care Unit (ICU) is commonly referred to as a place where caring is inextricably linked to high technology. The care in ICU often changes the patient into a taxpayer being left apart from its complexity and sometimes seen through a reductionist perspective. Thus, studies circa the care process are needed oriented from a historical ransom, raising the prospect of a more centralized human care. Hence, this study aimed to analyze the care process in a nursing intensive care unit from the perspective of the professional, family and patients. The study is characterized from a qualitative, descriptive and exploratory methodological approach. The actors were participating nursing professionals, patients and family members of an intensive care unit of Mossoró / RN. Data were collected in the period of May-June 2011, through interviews and observation of activities performed by nursing professionals, and their records in the chart. Data analysis was divided into topics and subtopics representing the phases and shapes that formed the collection. The analysis and discussion of the interviews were based on Bardin's proposal, when we created categories from a process of sorting and grouping criteria adequately defined. The observation of nursing records intended to observe the emphasis which is described in those notes as well as their consistency with practice of FCN and resolution 358/2009. The analysis showed that the nursing staff also performs work focused on mechanized activities and technical-bureaucratic institution that seem to override the needs of patients. In an overview, the care provided by professionals occurs either fragmented or insipient, however there is a service that involves other aspects beyond technical-curative practice, considering that major attention is given to the family and patient, focused on the concern of Nursing guiding their actions in not only the performance of procedures. However, the process of humanizing not always ends with an engagement between professional and patient, which mischaracterizes the true meaning of human care. The records also showed a tendency to focus on caring in a positivist line, where, in most cases, the factors of the disease and the obligation to meet the productivity have overshadowed other relevant aspects to a holistic understanding of caring. Regarding FCN Resolution No. 358/2009, which guides a systematization of nursing care, it is confirmed a technical view, a fragmented and superficial view of the patient, as well as a weakness of care, caused by ignorance and unpreparedness of the entire team. The perspective of caring demonstrates a reality with dialectic between what is proposed in a humane nursing and what happens in this performance space. Besides, it was shown a daily full of important considerations that arise in professional practice, in their views and also those people who were participants in the process

Teste de condutividade elétrica para a avaliação do vigor de sementes de abobrinha

O teste de condutividade elétrica da solução de embebição é recomendado para avaliar o vigor de sementes de ervilha e indicado para outras espécies, mas ainda há necessidade da continuidade de estudos sobre o assunto. A presente pesquisa foi desenvolvida com o objetivo de comparar procedimentos no teste de condutividade elétrica para avaliar o potencial fisiológico de sementes de abobrinha. Utilizaram-se sementes de abobrinha (Cucurbita pepo L.), cultivar Menina Brasileira, representadas por quatro lotes na primeira etapa e por outros cinco, na segunda. Foram conduzidos os teste de germinação, primeira contagem de germinação, emergência de plântulas, índice de velocidade de emergência e de condutividade elétrica. Para o teste de condutividade foram estudadas variações no volume de água (50 e 75mL), na temperatura (20, 25 e 30ºC) e no tempo de embebição (1, 2, 4, 8, 12, 16, 20 e 24 horas). O tempo de embebição para o teste de condutividade elétrica pode ser reduzido para 8 horas. Independentemente do volume de água, a temperatura de 30ºC foi a mais favorável para a ordenação consistente dos lotes quanto ao vigor. Assim, conclue-se que a condição mais adequada para o teste de condutividade elétrica em sementes de abobrinha é a utilização de 50 sementes em 75mL de água por oito horas, a 30ºC.

À beira do leito : sentimentos de pacientes durante a passagem de plantão em Unidade de Terapia Intensiva

This study aims to understand the feelings of patients admitted to the Intensive Care Unit (ICU) that experienced a change of shift at the bedside. The change of shift is one of the routines used by nursing in their work process and of great significance for the patient; therefore, deserves careful analysis in seeking to perfect themselves for the improvement of nursing care. It is a descriptive research, with a qualitative approach. The collection of information was performed using semi-structured interview, in August and September of 2011, after authorization from the Ethics Committee of the Federal University of Rio Grande do Norte, as opinion 290/2011. The analysis, based on interviews of patients, took the humanization as the thread of investigation backed by authors who deal on the subject and the theory of the gift of Marcel Mauss that sits on drug give-receive-return. The results indicate that the change of shift at the bedside but has not configured, the content of the speech of patients interviewed, as a moment that has generated fear and anxiety, could be deduced by the expression of silence, tears and other signs during interviews, how hard it is to live this experience. Nevertheless, despite this apparent tranquility, revealed uncertainty and apprehension face the speech of professional, during the visit at the bedside, particularly when referring to their health and their neighbors. On the other hand, the indifference to the participation of the patient at the time of the visit, expressing an attitude of merely technical nature, dehumanizes the act of taking care, the essence of nursing. And, for all the patients that we understand, about the visit to the bedside, as well as the ICU, we can infer that there is suffering for them. However, we understand your feelings and revelations seeking support in the theory of Mauss's gift: the patient receives the gift (care), and imbued with a feeling of gratitude, the rewards in the form of compliments and courtesies. Precisely for this reason, we need to sharpen our sensitivity to deal about the human condition in all its vulnerability.

Terapia comunitária integrativa: construção de um espaço de escuta para os trabalhadores na atenção básica da saúde

This research, which appears in the form of a dissertation, entitled: Integrative Therapy Community: construction of a listening space to health care workers in primary care, addresses the Integrative Community Therapy (ICT) as a tool to create meeting spaces between health professionals where they can be receptive among one another. With the completion of this study aimed to analyze the ICT as a therapeutic approach and space of listening and speaking for health professionals cited here in order to identify their anxieties, doubts, worries and uncertainties arising from the context of labor relations and the impact of therapeutic experiences under the view of the participants. It was developed as an action-science research, involving several steps. The field of research was the ICT meetings of workers from the units under the Family Health Strategy of Northern Health Districts I and II of the city of Natal, using a qualitative approach. The interpretation of data collected was based on content analysis proposed by Bardin. Finally, this study showed the ICT as a space for dialogue and sharing, with repercussions on labor relations and expansions beyond the ICT meetings, reaching out to family and social relationships, contributing to creating bonds and solidarity networks. Under the view of the participants it was recognized as an experience that optimized the socialization, promoting the alleviation of suffering and increasing the well-being. Based on the study findings, it is inferred that ICT can be considered a viable tool for the receptiveness and humanized care of health care workers.

Condutividade elétrica em sementes de abóbora, híbrido Bárbara

A condutividade elétrica na solução de embebição de sementes tem sido um procedimento usado com sucesso para avaliar o vigor de sementes. A presente pesquisa foi desenvolvida com o objetivo de determinar os procedimentos adequados para o teste de condutividade elétrica de sementes de abóbora (Cucurbita moschata Duch ex. Lam). Foram utilizadas sementes do híbrido Bárbara, representadas por cinco lotes (1 a 5) na primeira etapa e por outros cinco (6 a 10) na segunda. Foram realizados os teste de germinação, primeira contagem de germinação, emergência de plântulas, índice de velocidade de emergência e de condutividade elétrica (CE). Para o teste de CE, foram estudadas variações no volume de água (50 e 75mL), na temperatura (20, 25 e 30ºC) e no tempo de embebição (1, 2, 4, 8, 12, 16, 20 e 24 horas). Assim, concluiu-se que a condição mais adequada para o teste de CE é a utilização de 50 sementes em 75mL de água por oito horas, à temperatura de 25ºC.

Condutividade elétrica em função do teor de água inicial de sementes de amendoim

O vigor de sementes de amendoim (Arachis hypogaea L.) avaliado pelo teste de condutividade elétrica demonstra estreita relação com o desempenho no campo, mas alguns fatores podem afetar o resultado da condutividade elétrica, sendo um destes o teor de água inicial das sementes. Assim, o objetivo deste trabalho foi avaliar o teor de água ou faixa de umidade da semente mais adequado para a avaliação da condutividade elétrica em sementes de amendoim. Quatro lotes de sementes da cultivar 'IAC Tatu ST' e quatro da cultivar 'IAC Runner 886' foram avaliados quanto ao seu potencial fisiológico e posteriormente o teor de água foi ajustado para 5, 7, 9, 11, 13 e 15%, pelo método da atmosfera úmida. O delineamento foi inteiramente casualizado em esquema fatorial 4×6 (lotes × teores de água) para as sementes de cada cultivar, em quatro repetições e os resultados para o fator teor de água foram submetidos à análise de regressão. A maior relação da condutividade elétrica com vigor das sementes ocorreu naquelas com teor de água entre 9 a 15%, de forma que sementes com 5 a 7% de umidade não devem ser submetidas ao teste de condutividade elétrica, porque os lotes expressam alto padrão de germinação e vigor. A condutividade elétrica de sementes de amendoim é influenciada pelo teor de água e a estabilização dos resultados ocorre quando elas estão com teor de água entre 10 e 14%.

Teste de condutividade elétrica em sementes de maracujazeiro-amarelo

O teste de condutividade elétrica pode proporcionar informações importantes e complementares sobre o potencial fisiológico de sementes em período de tempo relativamente curto, visto que o teste de germinação se completa aos 28 dias para sementes de maracujá. Dessa forma, o objetivo deste trabalho foi avaliar a eficiência do teste de condutividade elétrica na avaliação do potencial fisiológico e padronizar a metodologia para sementes de maracujá-amarelo. Quatro lotes de sementes foram submetidos aos testes de germinação e vigor (primeira contagem, envelhecimento acelerado, índice de velocidade de germinação e emergência de plântulas em casa de vegetação), incluindo o teste de condutividade elétrica, conduzido com 25 e 50 sementes imersas em 50 e 75 mL de água desionizada,e as leituras realizadas após três, seis, nove, 12 e 24 h de embebição. Somente o lote 2 apresentou comportamento de baixo vigor apontado pelos testes de primeira contagem, emergência de plântulas e condutividade elétrica. A determinação do vigor de sementes de maracujá-amarelo por meio do teste de condutividade elétrica pode ser realizada utilizando 50 sementes e 75 mL após 24 h de embebição.

Teste de condutividade elétrica para sementes de mamoneira

The aim was to study the efficiency of electrical conductivity test in evaluating the quality of castor seeds. Emergence of seedlings was evaluated in the field, with five seed lots of cv. AL Guarany 2002. The seeds were submitted to the following tests: germination; first count of germination; accelerated aging (45 degrees C by 24 to 100% UR), emergence of seedlings in the field, rate of speed of development of seedlings and electrical conductivity, testing the periods (2, 4, 6, 8 and 24 hours) and the number of seeds (25,50 and 75) in 75ml of distilled water conditioning to 25 degrees C. A completely randomized design was used. The averages were compared by the Tukey test at 5%. The mean laboratory and field test data were correlated. Electrical conductivity test for 4 hours with 25 seeds and 6 hours with 50 seeds, and the rate of speed emergency proved efficient in the selection of lots vigor by providing information equivalent to the emergence of seedlings in the field.

Carga de trabalho de enfermagem e infecções relacionadas à assistência à saúde na unidade de terapia intensiva

In recent decades, the search for quality care has been widely discussed by the institutions and health professionals. In this context, it is the nurse coordinator of the process of providing nursing staff, reflecting the commitment to quality of care. In this process, it is the appearance of Infections Related to health care and its potential association with the workload in nursing as a valuable indicator of quality of care. Thus, this research contributes to studies to characterize the demand of nursing work to promote a safe healthcare practice. This study aimed to identify the association of nursing workload with the number of cases of Ventilator-Associated Pneumonia, urinary tract infection and central venous catheter infection in the intensive care unit. This is a quantitative research approach, descriptive, cross-sectional and prospective, held at Unimed Hospital in Natal-RN. The study population consisted of all patients treated in the Intensive Care Unit, Hospital for a period of 90 consecutive days in 2011. The convenience sample was compostapelos patients admitted to the ICU during the period of data collection, a total sample of 286 patients. To perform the data analysis software were used: Statistica 6.0, SPPS (Statistical Package for Social Sciences) version 17.0 (2004) and Excel 2007. In the descriptive analysis, we used Measures of Central Tendency and Measures of Dispersion or Variability and the use of nonparametric tests. Of the 286 patients, 88 were from the ICU and 198 ICU II II. Males predominated in the ICU I (51.1%) and female ICU II (57.6%) patients in the ICU I were aged 61-80 years (39.8%) followed by greater than 80 years (39.8%). In the ICU II, most of the patients were aged 61-80 years (38.9%) and then from 41 to 60 years (24.2%). In relation to the class of TISS inlet predominant class II in the two ICUs (59.1%), followed by Class III also in the two units (34.6%). Most patients (70.6%) out of the ICUs belonging to class II TISS. In the ICU I, the average number of forms of the TISS 28 was 6, has in ICU II this value drops to 3.2 forms. The overall mean was 19.9 TISS points in ICU patients I and ICU II.the 17 points in the average hours required to provide adequate nursing care to patients in the ICU I found that is 10 , 7 hours, and the ICU II 9.2 hours. It was found that the time provided by the nursing staff were higher in ICU II, with an average of 19 hours available for nurses in this sector. In the ICU I, which showed higher need of available hours, it was found that the mean value of 12.7 available hours. It was found that only 2.4% of patients had these units Ventilator-Associated Pneumonia, 1.0% were infected central venous catheter and 1.4% of patients had urinary tract infection. Infection associated with health care occurs, on average, on the tenth day of hospitalization. In the ICU II, this average value extends to the twelfth day with an excess of 2.7 hours of nursing care while in ICU I value decays to the ninth day of hospitalization with a deficiency of 12-hour assistance. It is concluded that patients generally showed a need for classification of semi-intensive care and has been assisted in their need to load. As for his association with the Related Infections Health will assist this analysis could not be performed due to the small number of notifications in this period. It is suggested further study how other factors related to infections me a longer period of analysis
