It has been studied the feeding patterns of Triatoma rubrovaria (wild triatominae bug, and intradomiciliary secondary vector of T. cruzi) in a rural area of "La Bolsa" (Department of Artigas). Agar double diffusion test were used for analyze the blood meal, from 120 insects, which were confronted to 13 antisera. It has 251 identify blood meals, and the most frequently was mammalian host (73%), but it has a variable source of feeding (mammals, birds, reptiles and cockroach), including humans rate 8% of the total. The identify of haemolimphe as feed, place this triatominae bug as an intermediary vector between predator and haematophagous. The most usual mammals are dasypodides and bovines. The frequence of human blood meal near the dwellings, shows its potentiality as vectors. Therefore, the peridomicile is an area of interaction between, domestic, wild and sinantropic host. The trypanosomic infection's rate at peridomiciles was lesser those at wild areas.
This paper describes population structure, spatial distribution and habitat selection of wild and peridomestic populations of Triatoma rubrovaria (Blanchard, 1843). Field studies were carried out at Las Piedras and La Bolsa in the Northern Department of Artigas, Uruguay. A semicircular sampling area, divided in seven or eight triangular sectors was sequentially examined from October 1990 to November 1991. At Las Piedras (typical wild habitat) 1063 T. rubrovaria bugs were collected from 84% of the rocky outcroops ("pedregales"). Abundance varied by season peaking in October-November (spring). Throughout the year, most of the population was made up of third, fourth and fifth instar nymphs; adults were found from October to March. In the peridomestic environment of La Bolsa, however T. rubrovaria was less common and showed a more irregular instar distribution. Colonized ecotopes, were those close to houses. In both sites T. rubrovaria was mainly associated with the geckonid Homonota uruguayensis and the cockroach Blaptica dubia.
RESUMOPesquisa qualitativa, exploratória descritiva, que objetivou conhecer a percepção dos receptores sanguíneos quanto ao processo transfusional. A pesquisa foi realizada em uma unidade de hemoterapia de um município da região sul do Brasil e os dados foram analisados por meio do Discurso do Sujeito Coletivo. Foram entrevistados, por meio de instrumento semiestruturado, onze pacientes, homens e mulheres entre 30 e 95 anos, em recuperação pós-cirúrgica de cirurgia cardíaca, submetidos à transfusão sanguínea. Emergiram quatro Ideias Centrais: Perda e reposição sanguínea; Preservação da vida; Reconhecimento do processo transfusional e Segurança transfusional. A percepção sobre a mudança que os pós-transfundidos começam a vivenciar a partir do processo transfusional traz à tona uma ressignificação da própria vida. Este estudo mostrou que os pacientes transfundidos percebem o processo transfusional como uma alternativa de sobrevivência e, mesmo tendo conhecimento sobre o processo e seus significados, permanecem receios e angústias que podem ser minimizados pela equipe multiprofissional. Descritores: Transfusão Sanguínea; Percepção; Enfermagem.
ABSTRACTQualitative research, descriptive exploratory, aimed to know the perception of blood transfusion recipients as to the process. The research was carried out at a blood bank in a city in southern Brazil, and the data were analyzed using the Collective Subject Discourse. Were interviewed using a semistructured instrument, eleven patients, men and women between 30 and 95 years, post-surgical recovery of cardiac surgery, underwent blood transfusion. Four central ideas emerged: loss and blood replacement; Preservation of life; Recognition of the transfusion process; and transfusion safety. The perception about the change that post-transfusion begin to live from the transfusion process raises a reframing of life itself. This study showed that transfused patients perceive the transfusion process as a means of survival, and even having knowledge about the process and their meanings, there is the permanence of fears and anxieties that can be minimized by the multidisciplinary team. Key words: Blood Transfusion; Perception; Nursing.
