The reduction of awareness incidence during anesthesia is related to the anesthesiologist improved scientific and technical performance, involving issues such as monitoring, comprehension of the anesthesia activity components, hypnotic and analgesic drugs, neuromuscular blocking agents, autonomic and motor reflex control, in addition to the risk factors involved in this event.
Increased markers in Group I (M5) suggests an increase in anaerobic metabolism (AM) in the splanchnic circulation while the highest values seen in Group II (GII > GI in M5, p<0.05%) suggest interference of another factor (deep anesthesia) responsible for the increase in AM, probably as a result of increased autonomic nervous system depression and minor splanchnic self-regulation.
Summary: Nunes RR, Porto VC, Miranda VT, Andrade NQ, Carneiro LMM -Risk Factors for Intraoperative Awareness.
Background and objectives:The intraoperative awareness is an adverse event in the general anesthesia, and may occur in approximately 20,000 cases per year, which justifies the study of the risk factors for this event. The objective of this study was to review this subject in order to reduce the incidence of intraoperative awareness and psychological sequelae incurring from this incident, which may result in post-traumatic stress disorder with negative repercussions on the surgical patient social, psychic and functional development.
Considerando o aumento do número de casos de câncer, em especial do câncer de mama, fica evidente a necessidade de identificar fatores de risco modificáveis da doença. Estudos relataram uma associação inversa entre o status de vitamina D e o risco de câncer de mama através da redução da densidade mamográfica, um conhecido fator de risco do câncer. O objetivo deste trabalho é definir se há associação entre vitamina D e densidade mamográfica e se esta associação pode reduzir o risco de câncer de mama. Foi realizada uma revisão integrativa da literatura, com os descritores em Ciências da Saúde “Vitamin D” AND “Mammographic Density” nas seguintes bibliotecas virtuais: MEDLINE, PUBMED, LILACS e SCIELO. Os estudos que avaliaram esta relação têm achados heterogêneos; uns mostram redução da densidade mamográfica nas pacientes com níveis séricos normais de vitamina D, e outros, não. Contudo, a dosagem insuficiente de vitamina D não deve ser desconsiderada, especialmente devido seu efeito comprovadamente importante na formação óssea e homeostase do cálcio.
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.
