Narratives of the convalescent plasma donor in a Peruvian social security hospital.: motivations, fears, expectations and experiences

Objectives: To know and explore from convalescent plasma donators' voices the experience in the blood donation process at a social security hospital. Methods: Qualitative study with a phenomenological design. The investigation was carried out in 01 hospitals of the social security of Peru. Semi-structured interviews were carried out. Results: Eleven donors of convalescent plasma were interviewed. The main motivations for donating were being able to contribute to national research and supporting patients affected by COVID-19. Fears focus on the possible risk of contagion within the hospital. Donors emphasised the attention and support of health personnel alongside the donation procedure. The main expectations and suggestions point towards greater dissemination of donation campaigns with special emphasis on safety. Likewise, an improvement in the time of the donation procedure (from enrolment to the extraction of convalescent plasma), and the implementation of friendly spaces to encourage future blood donation campaigns were highlighted. Conclusions: The experience of the convalescent plasma donors was positive. However, improvements must be made in terms of processes and infrastructure to ensure future successful blood donation campaigns.

Cytochemical findings in pleural fluid from patients with COVID-19, cared for in an emergency department

Objetive: The purpose of this work was to describe the physical, cytological and biochemical characteristics, as well as to classify the pleural fluids of patients with COVID-19 as exudates or transudates. Materials and Methods: An observational, descriptive cross-sectional study was carried out. Data was collected from the cytochemical examination of pleural fluid samples processed between the months of April to September 2020, in the laboratory of the Emergency Center of Metropolitan Lima (CELIM). Results: During the study period, a total of 81 samples of pleural fluid from patients with COVID-19 were evaluated, of these, 26 met our eligibility criteria. Fourteen liquids (54%) had a red color and 18 (69%) had a cloudy appearance. Exudative pleural fluids were the majority (n = 17), total proteins presented a mean of 3.3 g / dl (SD: 1.5), LDH a median of 544 U / L (IQR: 262-2016), the leukocyte count had a median of 610 leukocytes / ul (IQR: 180-968) and the differential polymorphonuclear count a median 29% (IQR: 15-60). Regarding the clinical characteristics, of the total exudates, 41% corresponded to neoplasms and 23% to pneumonia. While, of the total transudates (n = 9), 45% came from patients with neoplasms. Conclusions: In our study we observed that most of the pleural fluid samples from patients with COVID-19 were classified as exudates. These presented a low differential leukocyte percentage of polymorphonuclear cells. The values of the biochemical parameters such as total proteins and LDH were adequately related to the classification of exudates
