Escuta analítica no hospital geral: : implicações com o desejo do analista

Partindo da experiência na enfermaria de um hospital-escola1, do confronto com o status-quo do trabalho dos psicólogos em hospitais e da avaliação da literatura sobre a clínica psicanalítica em hospital, esta pesquisa se propôs a buscar avanços frente a uma questão específica: a escuta psicanalítica no trabalho em enfermarias de hospital geral e as implicações dessa prática com o desejo do psicanalista. Foram entrevistados quinze psicólogos declaradamente de orientação psicanalítica, vinculados a unidades de internação e com experiência mínima de dois anos de trabalho em hospital geral. As entrevistas foram abertas e semi-estruturadas, com o intuito de contemplar de maneira uniforme a coleta de informações de cunho mais objetivo, assim como de facilitar a pertinência ao tema de estudo. A interpretação dos dados foi realizada à luz do referencial clínico psicanalítico (freud-lacaniano), sendo que tal interpretação nos permitiu identificar uma importante interação entre os impasses, presentes na instituição hospitalar, da prática clínica psicanalítica com questões pessoais e de formação do profissional, interação que se vincula à postura de trabalho adotada no hospital. Reafirmamos, através desta pesquisa, a possibilidade de fazer uso de uma escuta analítica no trabalho com pacientes internados, a qual está sempre voltada para as manifestações do inconsciente ao longo da fala, e na qual a direção do tratamento é a emergência do sujeito do inconsciente.

Modificacoes na ação mecânica do coração isolado de cobaia por doses de propafenon capazes de alterar o eletrocardiograma

Inotropic effects of Propafenon were studied in isovolumic isolated guinea pig hearts submitted to infusion of the drug during 10 minutes. The dosages utilized caused: bradycardia, depression of AV nodal conduction and QRS widening. Simultaneously there was: decrease of the developed pressure (DP) and of the rate of rise of pressure (dp/dt), and elongation of the time of peak pressure. Since there was no clear relation between the heart rate and the inotropic indices (PD and dp/dt), it could be supposed that the depressor effect was not due to impairment of the chronotropism only. After the infusion of Propafenon, the chronotropic effect disapeared after 15 min, while the inotropic state presented a less satisfatory recuperation. The coronary output accompanied the myocardial metabolic needs, that is to say, there was a fall during the period of depressed cardiac function and a later tendency to increase during recovery.

Ação do diclofenaco de sódio, após a interrupção da peritonite estercorácea, no cólon de ratos. Estudo da resistência mecânica e do colágeno tecidual.

The objective of the present study was to investigate changes in colon wall in rats with fecal peritonitis (Per) associated with sodium diclofenac (SD) by studying breaking strength and tissue collagen concentration. The rats were divided into the following experimental groups: GROUP 1-SD: 60 animals injected intramuscularly with sodium diclofenac at the dose of 2 mg/kg body weight; GROUP 2-Per: 60 animals injected intraperitoneally with a suspension of human feces. Peritonitis was interrupted after six hours of evolution; GROUP 3-Per+SD: 60 animals injected intraperitoneally with a suspension of human feces and receiving SD according to the schedule used for Groups 1 and 2; CONTROL GROUP: 12 animals injected intramuscularly with physiological saline. The animals of Group 1, 2 and 3 were successively sacrificed 2, 4, 7, 14 and 21 days after interruption of peritonitis an/or the beginning of treatment. Under conditions of the experimental model and of the methods used, we conclude that sodium diclofenac, peritonitis and the peritonitis-sodium diclofenac association decrease the breaking strength and the concentration of tissue collagen in the colon segment.

Filmes de metal-hexacianoferrato: Uma ferramenta em química analítica

Chemically modified electrodes based on hexacyanometalate films are presented as a tool in analytical chemistry. Use of amperometric sensors and/or biosensors based on the metal-hexacyanoferrate films is a tendency. This article reviews some applications of these films for analytical determination of both inorganic (e.g. As3+, S2O3 2-) and organic (e.g. cysteine, hydrazine, ascorbic acid, gluthatione, glucose, etc.) compounds.

Efeito da posição do prematuro no desmame da ventilação mecânica

Objective: the purpose of this study was to determine the effects of prone positioning on cardiorespiratory stability and weaning outcome of preterm infants during weaning from mechanical ventilation. Methods: from January to December 1999, a sample of 42 preterm infants, with birthweight < 2,000 g, mechanically ventilated in the first week of life, were randomly divided, in the beginning of the weaning process, in two groups according to the position: supine position (n = 21) or prone position (n = 21). Heart rate, respiratory rate, transcutaneous oxygen saturation and ventilatory parameters were recorded every one hour. Length of the weaning process and complications were also assessed. Results: in both groups the mean gestational age was 29 weeks, most of the patients presented very low birthweight and respiratory distress syndrome. The mean length of the weaning process was 2 days. There were no differences between the groups regarding respiratory rate, heart rate and transcutaneous oxygen saturation, however, oxygen desaturation episodes were more frequent in supine position (p = 0.009). Ventilatory parameters decreased faster and reintubation was less frequent in the prone group (4% versus 33%). No adverse effects of prone positioning were observed. Conclusion: these results suggest that prone position is a safe and beneficial procedure during the weaning from mechanical ventilation and may contribute to weaning success in preterm infants.

Diagnóstico de uma área compactada por atividade minerária, na floresta amazônica, empregando métodos geoestatísticos à variável resistência mecânica à penetração do solo

A quite common problem in the recovery of degraded areas in the mineral exploration understands the compaction of the soil due to the intense traffic of machines and earth movement. The most common problem of the compaction of a degraded surface is: increase of the mechanical resistance to the penetration of the rooats, reduction of the aeration, alteration of the water flow and heat. Thus the present work had the basic objective of diagnosing the compaction of a degraded area by mining in a space way, through the mechanical resistance the way penetration to guide a future subsoiling in the place seeking recovery. Through the studies it was concluded that the kriging method in agreement with the space variation allows the division of the area studies in sub areas facilitating a future work to reduce cost and unnecessary interference to the atmosphere. The method was shown quite appropriate and it can be used in diagnosis of the compaction in a degraded area by mining, foreseeing subsoiling need.

Estudo de metodologia analítica para a determinação do cetoconazol em formulações farmacêuticas

Ketoconazole is a synthetic broad-spectrum oral and topical antifungal drug derived from imidazole, effective in the treatment of superficial mycoses and systemic infections. In this study we have tested several methods to analyze ketoconazole in various pharmaceutical products containing this drug, employing techniques such as UV and IR spectrophotometry and thermal analysis. The results showed that UV spectrophotometry is a fast, practical and economical method and indicated that other methods, such as IR spectrophotometry and thermal analysis, could be good alternative methods for ketoconazole analysis in certain pharmaceutical forms.

Temperatura, escarificação mecânica e substrato na germinação de sementes das palmeiras juçara e açaí

The propagation of 'juçara' and 'açaí' is done by seeds, but there is a great desuniformity in the germination process. In this way, the objective of this study was to verify the effect of temperature, mechanical scarification and substrate on seed germination of both species. Two experiments were conducted in a completely randomized design, with four replications each consisting of 25 seeds. The first was conducted with 14 treatments in factorial scheme 7 x 2, seven temperatures (20, 25, 30, 35, 20-30 and 25-35 °C and natural condition), with and without mechanical scarification. The second was constituted of eight treatments in factorial scheme 4 x 2, four substrates (sand, vermiculite, coconut fiber and soil + manure), with and without mechanical scarification. Seeds of 'juçara' palm present the highest mean percentage and germination speed index in alternating temperatures of 20-30 and 25-35 °C and natural condition and in substrates sand, vermiculite and coconut fiber. Temperatures of 30, 35, 20-30 and 25-35 °C and natural condition in all substrates tested were the most favorable condition for 'açai' seeds. The scarification of the seeds was favorable to the germination process of 'juçara' whereas the seeds of açaí does not need to be scarified.

Caracterização analítica de sucos e néctares de laranja adoçados com sacarose e edulcorantes

Objective: To characterize physically and chemically, non-sweetened orange juices and orange nectars sweetened with sucrose or sweet flavoring agents, with respect to their pH, titratable acidity (TA) and total soluble solids content (TSSC), as well as to evaluate the correlation of the latter property with the others. Method: Aliquots of three lots of two orange juices and two orange nectars containing sucrose and two containing sweet flavoring agents were evaluated. Mineral water was used as a control. The TSSC was determined using an Abbe refractometer. The pH was recorded using a digital pH meter, while TA was quantified by titrating samples of the beverages with 0.1 M NaOH until reaching pHs 5.5 and 7.0. Data were subjected to Pearson's correlation test, regression analysis, analysis of variance and Tukey's test (α=0.05). Results: TSSC values presented a strong correlation with TA, and these properties exhibited a quadratic relationship. Although the pH values were not dependent on the presence of sucrose or sweet flavoring agents, a significantly greater amount of base was necessary to reach pHs 5.5 and 7.0 in the beverages without sucrose or flavoring agents. Conclusion: Orange juices and nectars presented similar pH values, which was not associated with the presence of sucrose or sweet flavoring agents in the beverages. Higher TA values were obtained for the juice and lower for the nectars, regardless of containing sucrose or sweet flavoring agents. The increase of TSSC did not implicate in decrease of TA in the beverages.

Variabilidade espacial da resistência mecânica do solo à penetração e umidade do solo em área cultivada com cana-de-açúcar na região de Humaitá, Amazonas, Brasil

The mechanical resistance to penetration (RP) is an attribute indicator of compaction was influenced by soil moisture. The objective of this study was to evaluate the spatial variability of soil resistance to penetration and soil moisture on area under cultivation of sugar cane in the region of Humaitá, Amazonas, Brazil. We conducted a sampling grid of 70x70 m where points were scored at regular intervals of 10 m, a total of 64 points. Soil samples were collected at depths of 0.00 to 0.15 m, 0.15 to 0.30 I 0.30 to 0.45 m for determination of soil moisture and soil resistance to penetration in the field. After analysis of these data analyzes were descriptive statistics and geostatistics. We conclude that all the variables studied showed spatial dependence and range values were higher than stipulated by the sampling grid and the RP and soil moisture showed a spatial relationship where lower values of PR concentrated on smaller values of soil moisture.
