Análise comparativa entre métodos de estimativa de estatura em pacientes de um complexo de terapia intensiva / Comparative analysis between height estimation methods in patients of an intensive care complex

Objetivo: verificar a acurácia de quatro fórmulas de estimativa de estatura quando comparadas à altura real de pacientes internados em um complexo de terapia intensiva. Metodologia: estudo prospectivo analítico. Realizado por meio de coleta de dados e aferição de medidas em 66 pacientes. Para avaliar a acurácia das fórmulas, o teste t-student para amostras pareadas foi utilizado. Resultados: as fórmulas que utilizam a altura do joelho como parâmetro mostraram alta correlação com a altura real, sendo superiores às fórmulas que utilizam a medida da ulna. Conclusão: as estimativas são bons métodos para obter a estatura do paciente quando não é possível aferi-la.

Objective: to verify the accuracy of four height estimation formulas compared to the actual height of patients admitted to an intensive care complex. Methodology: prospective analytical study. Performed by means of data collection and measurement taking for 66 patients. To evaluate the accuracy of the formulas, the t-student test for paired samples was used. Results: the formulas that use the knee height as a parameter showed a high correlation with the actual height, being superior to the formulas that use the measurement of the ulna. Conclusion: estimates are good methods to obtain the height of the patient when it is not possible to measure it.

Demographic and clinical characteristics of patients undergoing coronary artery bypass graft surgery and their relation to mortality.

OBJECTIVE: To describe the demographic and clinical characteristics and to test their relation to mortality in patients undergoing to coronary artery bypass graft surgery (CABG). METHODS: It is a retrospective study developed from the medical records of 655 patients undergoing CABG from May 2002 to April 2010. RESULTS: Hospital mortality was 12.1%. Mortality was significantly (P<0.05) higher in females (17.3%), aged less than 70 years (22.8%), in emergency surgery (36.4%), in cases of readmission to the intensive care unit (ICU) (33.3%), when the stay in the ICU was less than three days (16.3%), undergoing longer cardiopulmonary bypass (CPB) and with more comorbidities (15.4%). Predictor variables of death identified with logistic regression analysis were: female (OR=2.04), age >70 years (OR=2.69), emergency surgery (OR=15.43) and urgency (OR=3.81), performance of CPB (OR=2.19) and re-admission to the ICU (OR=4.33). CONCLUSION: Variables such as gender, age, type of surgery, readmission to the ICU, ICU stay, comorbidities and time of CPB influence the outcome death in patients undergoing to CABG. Thus, such aspects should be considered to reduce hospital mortality in patients undergoing such surgery.

Características clínico-demográficas de pacientes submetidos a cirurgia de revascularização do miocárdio e sua relação com a mortalidade / Demographic and clinical characteristics of patients undergoing coronary artery bypass graft surgery and their relation to mortality

OBJETIVO: Descrever as características clínicodemográficas e testar sua relação com a mortalidade hospitalar em pacientes submetidos à cirurgia de revascularização do miocárdio (CRM). MÉTODOS: Estudo retrospectivo conduzido a partir dos prontuários de 655 pacientes submetidos à CRM, no período de maio de 2002 a abril de 2010. RESULTADOS: A mortalidade hospitalar foi de 12,1%. A mortalidade foi significativamente (P<0,05) maior em indivíduos do sexo feminino (17,3%), com idade igual ou superior a 70 anos (22,8%), em cirurgias de emergência (36,4%), nos casos de reinternação na unidade de terapia intensiva (UTI) (33,3%), quando a permanência foi inferior a três dias na UTI (16,3%), submetidos a maior tempo de circulação extracorpórea (CEC) e com maior número de comorbidades (15,4%). As variáveis preditoras de óbito identificadas pela análise de regressão logística foram: sexo feminino (OR=2,04); idade >70 anos (OR=2,69); cirurgias em caráter de emergência (OR=15,43) e de urgência (OR=3,81); realização de CEC (OR=2,19) e reinternação na UTI (OR=4,33). CONCLUSÃO: Sexo, idade, tipo de cirurgia, reinternação na UTI, permanência na UTI, comorbidades e tempo de CEC influenciaram no desfecho óbito do paciente submetido à CRM. Dessa forma, tais aspectos devem ser considerados para diminuir o óbito hospitalar em pacientes submetidos a esse tipo de cirurgia.
