Atuação dos profissionais de enfermagem durante o processo transfusional na UTI de um hostital universitário

Prospective descriptive study with quantitative approach, which aimed to analyze the relationship of the knowledge of Nurses and conduct assistance during the process of transfusion, to patients in the ICU of a university hospital in Natal-RN. The sample consisted of 27 professionals from the nursing staff (5 nurses and 22 nursing technicians), climbing in the ICU during the period of data collection. Data collection was through a questionnaire and structured form of observation, in addition to consulting the diary. The results were organized in SPSS 15.0, tabulated, cathegorized and analyzed by descriptive and inferential statistics. The results show a young population, aged between 21 and 32 years (63.0%), female (85.2%). Among those surveyed were the main type of stock, mostly technical, nursing (ρ= 0006), which have little time to experience - up to 2 years (ρ= 0008), did not know the DRC in 153 (ρ= 0019), held greater number of pipelines care in blood (ρ= 0018), the non-participation in training and feel informed about the process of transfusion, showed no significant differences. As for officials, highlighted only the time to experience more than 2 years, carrying out fewer procedures and feel informed about the blood. As for the pipes during the transfusion process, I found that the majority of pipes observed in both the stock and the staff were inadequate, with predominance in the first, both in the pursuit of conduct regarding the shortfall. The averages of inappropriate conduct, predominantly developed by stock, were higher in all stages for appropriate conduct. Analyzing the knowledge about the disease process, the stock market were those who had lower scores of knowledge in three stages. As the relationship between the pipes care and knowledge, we see that at all stages of the process of transfusion inadequate knowledge of the averages were higher, taking a significant difference in the stages pre-transfusion (ρ= 0012). When analyzing the average of pipes behind, we see that in inappropriate conduct were significantly higher (ρ= 0031), who had searched in inadequate knowledge. As for the frequency of total procedures performed, we found a significant predominance (ρ= 0049) of inappropriate conduct (88.9%) of which 81.5% were developed by professionals who had inadequate knowledge, showing moderate correlation (r = 0,516) and odds ratio of 2,750 times the development of inappropriate conduct in trade with inadequate knowledge. We conclude that the professionals surveyed, especially the technicians of nursing stock, showed serious deficiencies with regard to the development of pipelines and knowledge of the transfusion process, showing the inadequacy to develop this therapy. Facing the foregoing, we accept the alternative hypothesis proposed in the study, because we show that the inadequacy of knowledge about the process of transfusion influence in inappropriate conduct implemented by the nursing staff in ICU.

Uma análise exploratória da jornada flexível de trabalho sob a perspectiva de tutores na educação a distância

Information Age has been providing accelerated development of technologies in teaching, which is making the increase in distance courses and flexibility in the tutors everyday work. In this context, it was aimed to study the influence of flexible work in the development of activities and personal life of the tutors in Distance Education at Universidade Federal do Rio Grande do Norte. More specifically, they have been sought to compare the types of flexibility detected, identifying the extent of the day's work in mentoring; investigating the relationship between flexible working time and productivity; evaluating the Quality of Working Life (QWL) and for Work and Family Relationship of the tutors. Thus, work is justified by the importance of academic and organizational achievement. To meet the goals, it was obtained a sample of 75 respondents (45.73% of the population). The data collection instrument was comprised of 48 variables mainly based by Walton (1975) and Paschoal, Tamayo and Barham (2002). The statistical techniques used were: analysis of frequency, ratio test, factor analysis and regression. The results collected have shown that the presence and distance tutors experience similar realities, but have different profiles; the day of their work is on average three hours daily; in view of the tutors, flexibility has a relation with the production, QWL work-family balance were evaluated in a satisfactory manner and the statistical techniques used have shown significant influence between the QWL and flexible working day. It is therefore concluded that flexibility at work can influence the development of activities and personal life of the tutors. Thus, the flexible working day may be used in a strategy way of routine in many organizations

Conectores sequenciadores e e aí em contos e narrativas de experiência pessoal escritos por alunos de ensino fundamental: uma abordagem sociofuncionalista

In this dissertation, based on two theoretical frameworks, American functionalism and variationist sociolinguistics, I take as subject the sequence connectors E and AÍ, which has the grammatical function of indicating retroactive-propeller sequenciation of information. I analyze the variable use of these connectors in texts written by students from two public schools in the city of Natal, RN, attending at the time of data collection (the year 2012), two distinct levels of basic education: the sixth and the ninth year. The students who contributed to this research wrote, as part of their activities in the classroom, texts of two narrative genres: narrative of personal experience (non-fictional) and short story (fictional). In addition, these students and their Portuguese teachers answered a test of linguistic attitude in which they gave their opinions regarding the appropriateness of the use of connectors E and AÍ in contexts of speech and writing marked by distinct degrees of formality. The results obtained by means of quantitative analysis showed different tendencies of linguistic, social and stylistic distribution of connectors E and AÍ in the narrative texts written by the students. I related these results to the action of two principles: the principle of persistence, linked to the process of change by grammaticalization, and the principle of stylistic markedness. Besides, I took into account the answers provided by students and teachers to the test of linguistic attitude for refine the interpretation of the results

O tratamento odontológico sob o olhar da criança :um estudo de representações sociais

Oral health measures directed to children are characterized by the lack of policies that consider the individual and his biopsychosocial aspects. As a consequence, it can be observed that a child´s dental experience has normally been prejudged as unpleasant and threatening. Thus, this study is aimed at investigating dental treatment from the child´s viewpoint using the theory of social representations for theoretical/methodological support. This theory was selected for being able to build practical knowledge surrounding the interrelations between social actors, the phenomenon and the world around them. The investigation was performed at the Professor José Fernandes Machado State School, located in the Ponta Negra district of Natal-RN-Brazil. The participants consisted of 30 children from the public elementary school system in the 6-10 year age group, who had undergone dental treatment within the previous year or were being treated at the time of data collection. An in-depth interview and story drawing within a theme were used as collection instruments. Thematic Content Analysis (Bardin, 2002) was used to analyze the material collected in the interviews, whereas for story drawing within a theme, in addition to content analysis, the data were also analyzed by the Coutinho model (2001). The two instruments demonstrated similarity of content as well as complementarity and contained categories associated to the model for dental treatment in children, the description of the dental office environment., the perception of the image of the dentist, as well as psychological and behavioral manifestations. The results enable us to understand determinate reactions of the children in relation to dental treatment, which has been characterized by its technical-curative approach, where the motive for seeking treatment, the manner in which it is performed and the relation of the dentist with the child are all in evidence. Thus, this study intends not only to reveal the viewpoint of children faced with dental treatment, but also to contribute to a dental practice directed towards them, in this way instilling in the professionals who attend them a more concrete awareness of the needs, anxieties and feelings of these young patients

A experiência de depressão na contemporaneidade: uma compreensão fenomenológico-existencial

The depression is one of the most common forms of getting ill nowaday. Due to the increase in incidence of depression cases registered worldwide, this theme has been the subject of important studies, especially regarding the symptomatological description and biological etiology of the disease. This research had the objective to understand the unique experience of depression experienced by people who recognize themselves in depression, under the focus of existential phenomenology of Martin Heidegger. To reach the proposed objective, individuals narratives interviews were conducted with four participants, starting from the triggering question, "from your experience, how is for you to being depressed?". The survey revealed that depression affects the whole person and is related to stressful life contexts. Depression was narrated as an experience of disempowerment and lack of self esteem and personal worth. The collaborators of the research referred to the depression from sad, angry, bored and pessimistic mood. The time is experienced as a restriction to the projective opening towards the possibilities of being in which the future is seen as catastrophic and the past lived as debt and guilt. The corporeality, in depression is experienced through the weight, fatigue and pains for no reason. The space is lived from the notion of fall and collapse. We also realized the desire for isolation and avoidance of social contact. Suicide is desired and represents the end of the suffering in life. The depression has proved, still, very stigmatized, because it is discredited and misunderstood. The stigma also addressed to the experience of hospitalization and the unsuitability to the socially imposed standards of beauty, which generates enough suffering to the depressed person. The medication was described based on its positive effects, as a balance and suffering reducer, but also as a producer of dependence. Were also identified according to the collaborators, traces of selfdemand, ordenality and being-for-others, characteristic of typus melancholicus. This study contributes to an understanding of the depression that goes beyond the merely biological perspective and symptomatology of the pathology. The investigation of the depressive experience, through the lens of Heidegger's phenomenology, showed us the phenomenon of the depression in their singularity, complexity and multiple meanings, showing the close relationship between the formation of the depression and the context of personal and social life of the participants

Giving up reporting the aggressor: reports of female victims of domestic violence

The goal of this study is to describe the experience of female victims of domestic violence, who forfeited the lawsuits against their aggressors. The interviews were oriented by the question: What was your experience of forfeiting the denunciation of your aggressor? Three themes emerged from the convergence of the testimonies: time passed from the aggression to the denunciation and then to the forfeiting; the partner, the family, the women's precinct; reflecting about the experience, which described the studied phenomenon. The women expressed ambiguous feelings for their aggressor: affection, anger, humiliation and fear. They recognize that they are dominated and humiliated, but notions of justice and equality between spouses do not appear in the testimonies. Forfeiting can be understood in the context of the reproduction of the traditional family structure, conditioned to economic and social factors. Results highlight implications about the role of the Women's Precinct and the healthcare institutions in the care for women who were victims of domestic violence.

Strategies to improve the ovarian response to equine pituitary extract in cyclic mares

Equine pituitary extract (EPE) has been reported to induce heightened follicular development in mares, but the response is inconsistent and lower than results obtained in ruminants undergoing standard superovulatory protocols. Three separate experiments were conducted to improve the ovarian response to EPE by evaluating: (1) effect of increasing the frequency or dose of EPE treatment; (2) use of a potent gonadotropin-releasing hormone agonist (GnRH-a) prior to EPE stimulation (3) administration of EPE twice daily in successively decreasing doses. In the first experiment. 50 mares were randomly assigned to one of four treatment groups. Mares received (1) 25 mg EPE once daily; (2) 50 mg EPE once daily (3) 12.5 mg EPE twice daily; or (4) 25 mg EPE twice daily. All mares began EPE treatment 5 days after detection of ovulation and received a single dose of cloprostenol sodium 7 days postovulation. EPE was discontinued once half of a cohort of follicles reached a diameter of greater than or equal to35 mm and hCG was administered. Mares receiving 50 mg of EPE once daily developed a greater number (P = 0.008) of preovulatory follicles than the remaining groups of EPE-treated mares, and more (P = 0.06) ovulations were detected for mares receiving 25 mg EPE twice daily compared to those receiving either 25 mg EPE once daily and 12.5 mg EPE twice daily. Embryo recovery per mare was greater (P = 0.05) in the mares that received 12.5 mg EPE twice daily than those that received 25 mg EPE once daily. In Experiment 2, 20 randomly selected mares received either 25 mg EPE twice daily beginning 5 days after a spontaneous ovulation. or two doses of a GnRH-a agonist upon detection of a follicle greater than or equal to35 mm and 25 mg EPE twice daily beginning 5 days after ovulation. Twenty-four hours after administration of hCG, oocytes were recovered by transvaginal aspiration from all follicles greater than or equal to35 mm. No differences were observed between groups in the numbers of preovulatory follicles generated (P = 0.54) and oocytes recovered (P = 0.40) per mare. In Experiment 3, 18 mares were randomly assigned to one of two treatment groups. Then, 6-11 days after ovulation, mares were administered a dose of PGF(2gamma) and concomitantly began twice-daily treatments with EPE given in successively declining doses, or a dose of PGF(2alpha), but no EPE treatment. Mares administered EPE developed a higher (P = 0.0004) number of follicles :35 mm, experienced more (P = 0.02) ovulations, and yielded a greater (P = 0.0006) number of embryos than untreated mares. In summary, doubling the dose of EPE generated a greater ovarian response, while increasing the frequency of treatment, but not necessarily the dose. improved embryo collection. Additionally, pretreatment with a GnRH-a prior to ovarian stimulation did not enhance the response to EPE or oocyte recovery rates. (C) 2002 Elsevier B.V. All rights reserved.

Early social environment and the fighting behaviour of young Oreochromis niloticus (Pisces, Cichlidae)

This study examines the influence of early experience with different forms of aggressive behaviour on the fighting behaviour of young fish. Fry of the cichlid fish, Oreochromis niloticus, were raised from hatching in small groups consisting of a normal individual (the test fish) and either mutant conspecifics lacking the dorsal fin and thereby the ability to perform fin displays, or normal ones. Following a 63-day period of development in groups the test fish were confronted in their home tanks with an unfamiliar normal fish for 10 min. The fighting behaviour of the test fish was analyzed considering their previous group type (mutant or normal) and rank (alpha or beta). There was no difference between test fish in the rate and sequence of behaviour patterns used in fighting. However, test fish that had developed in mutant groups were rarely the first to bite in contests and had a longer latency to biting following the first bite of the stimulus fish than rest fish with normal experience. This finding is attributable to the form of aggressive behaviour experienced by the test fish during development but not to existing differences in the amount of aggression previously experienced, nor to previous rank, sex, or size relative to the stimulus fish. The results suggest that early experience influenced decision making by the test fish during the fight. The involvement of the fin displays and the possible mechanism of this influence are discussed.

On the scattering of comets by a planet

In this paper, numerical simulations are made, using the three-dimensional restricted three-body problem as the mathematical model, to calculate the effects of a swing-by with the planet Saturn in the orbit of a comet. To show the results, the orbit of the comet is classified in four groups: elliptic direct, elliptic retrograde, hyperbolic direct and hyperbolic retrograde. Then, the modification in the orbit of the comet due to the close approach is shown in plots that specify from which group the comet's orbit is coming and to which group it is going. Several families of orbits are found and shown in detail. An analysis about the trends as parameters (position and velocity at the periapse) vary is performed and the influence of each of them is shown and explained. The result is a collection of maps that describe the evolution of the trajectory of the comet due to the close approach. Those maps can be used to estimate the probability of some events, like the capture or escape of a comet. An example of this technique is shown in the paper. (C) 2005 COSPAR.

Effect of remifentanil hydrochloride administered via constant rate infusion on the minimum alveolar concentration of isoflurane in cats

Objective - To evaluate the effects of increasing doses of remifentanil hydrochloride administered via constant rate infusion (CRI) on the minimum alveolar concentration (MAC) of isoflurane in cats. Animals - 6 healthy adult cats. Procedures - For each cat, 2 experiments were performed (2-week interval). On each study day, anesthesia was induced and maintained with isoflurane; a catheter was placed in a cephalic vein for the administration of lactated Ringer's solution or remifentanil CRIs, and a catheter was placed in the jugular vein for collection of blood samples for blood gas analyses. On the first study day, individual basal MAC (MAC Basal) was determined for each cat. On the second study day, 3 remifentanil CRIs (0.25, 0.5, and 1.0 μg/kg/min) were administered (in ascending order); for each infusion, at least 30 minutes elapsed before determination of MAC (designated as MAC R0.25, MAC R0.5, and MAC R1.0, respectively). A 15-minute washout period was allowed between CRIs. A control MAC (MAC Control) was determined after the last remifentanil infusion. Results - Mean ± SD MAC Basal and MAC Control values at sea level did not differ significantly (1.66 ± 0.08% and 1.52 ± 0.21%, respectively). The MAC values determined for each remifentanil CRI did not differ significantly. However, MAC R0.25, MAC R0.5, and MAC R1.0, were significantly decreased, compared with MAC Basal, by 23.4 ± 79%, 29.8 ± 8.3%, and 26.0 ± 9.4%, respectively. Conclusions and Clinical Relevance - The 3 doses of remifentanil administered via CRI resulted in a similar degree of isoflurane MAC reduction in adult cats, indicating that a ceiling effect was achieved following administration of the lowest dose.

Razões para substituição de restaurações em clínica integrada

Objective: To analyze the reasons for replacing amalgam and composite resin restorations of patients treated at the Integrated Clinic Discipline of the Dental School of Araçatuba (UNESP), SP, Brazil. Method: After examining the patients for data collection to obtain a diagnosis, the treatment plan was outlined using a clinical form containing the restorations to be replaced, the reasons for replacing, the restorative material of choice and the number of restored surfaces. Next, all restorations indicated for replacement were examined as to their real need of replacement by 5 calibrated examiners taking into account the theorical concepts on the proposed criteria for the need of replacing or not. The analyzed period comprised 5 years (2001 to 2005). The criteria adopted for replacement were attached to the data collecting form in order to standardize the analysis of the restorations. Results: 856 patients were treated within the studied period and 753 needed restoration replacement. The main reasons for replacing amalgam restorations were defective marginal adaptation (40.9%), recurent caries (24.1%) and deficient anatomical form (15.4%). The main reasons for replacing resin restorations were esthetics (31.4%), defective marginal adaptation (29.2%) and recurent caries (20.7%). Conclusion: In spite of the little clinical experience of the studied population (undergraduate students), the reasons for replacing restorations were in accordance with the literature, having estehtics as the main reason for the replacement of composite resin restorations and defective marginal adaptation for amalgam restorations.
