Complicações verificadas no pós-operatório podem ser compreendidas como respostas ineficazes do modelo de adaptação de Roy frente à estratégia de coping gerada pela cirurgia cardíaca eletiva. Objetivos: Identificar as complicações do pós-operatório imediato de adultos e idosos submetidos a cirurgias cardíacas eletivas com uso de circulação extracorpórea; Categorizar as complicações do pós-operatório imediato identificadas como respostas ineficazes do modo fisiológico do sistema adaptativo humano. Metodologia: Estudo do tipo observacional retrospetivo, transversal, de objetivo exploratório e descritivo. Foram analisados os registos do período pós-operatório imediato de 230 pessoas submetidas à cirurgia cardíaca eletiva com uso de circulação extracorpórea no período de janeiro de 2013 a dezembro de 2015. Resultados: Foram identificadas 423 complicações no pós-operatório imediato, estando relacionadas, na sua maioria, com o equilíbrio de fluidos, eletrólitos e ácido-base e função endócrina. Conclusão: A leitura das complicações pós-operatórias como respostas ineficazes amplia a participação avaliativa e de intervenção da equipa de enfermagem durante o período pós-operatório, garantindo uma direção disciplinar singular. Palavra-chave: cirurgia torácica; procedimentos cirúrgicos cardiovasculares; complicações pós-operatórias; teoria de enfermagem; enfermagem
Summary The influence of the method of evaluating developmentally competent oocytes on their viability after cryopreservation still needs to be better understood. The objective of this study was to determine the cleavage and embryo developmental rates after parthenogenetic activation of cumulus–oocyte complexes (COCs) selected by different concentrations of brilliant cresyl blue (BCB) and cryopreservation. In the first experiment, COCs were separated into groups and incubated for 1 h in medium containing BCB (13 μM, 16 μM, or 20 μM). The control group was not exposed to BCB staining. In the second experiment, COCs were divided into four groups: 13 μM BCB(+), 13 μM BCB(−), fresh control (selected by morphologic observation and immediately in vitro matured) and vitrified control (selected by morphologic evaluation, vitrified, and in vitro matured). In the first experiment, the 13 μM BCB group displayed greater development rates at the morula stage (65.45%, 36/55) when compared with the other groups. In the second experiment, cleavage (47.05%, 72/153) and morula development (33.55%, 51/153) of the control group of fresh COCs were increased compared with the other groups. However, when comparing morula rates between vitrified COC control and BCB(+) groups, the BCB(+) group had better results (19.23%, 5/26 and 64.7%, 11/17, respectively). Our best result in rat COC selection by BCB staining was obtained using a concentration of 13 μM. This selection could be a valuable tool to improve vitrification outcomes, as observed by the BCB(+) group that demonstrated better results compared with the vitrified COC control.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
