ABSTRACT

ABSTRACT Objective: To characterize the sound alarms of the Intra-Aortic Balloon Pump (IABP) during aortic counterpulsation therapy; to measure the stimulus-response time of the team to these; and to discuss the implications of increasing this time for patient safety from the alarm fatigue perspective. Method: This is an observational and descriptive study with quantitative and qualitative approach, case study type, carried out in a Cardiac Surgical Intensive Care Unit. Results: The most audible IABP alarm was the one of high priority increased-reduced diastolic blood pressure. The stimulus-response time was 33.9 seconds on average. Conclusion: Managing the alarms of these equipment is essential to minimize the occurrence of the alarm fatigue phenomenon and to offer a safer assistance to patients who rely on this technology.


RESUMEN Objetivo: Caracterizar las alarmas sonoras disparadas por el balón de contrapulsación intraaórtico (BCIA) durante la terapia de contrapulsaciónaórtica; calcular el tiempo estímulo-respuesta del dispositivo y discutir las implicaciones al extenderse el tiempo para la seguridad del paciente cuando presente fatiga por las alarmas. Método: Estudio descriptivo observacional, con enfoques cuantitativo y cualitativo, de tipo estudio de caso, llevado a cabo en una Unidad de Cuidado Cardiontensivo Quirúrgico. Resultados: La alarma sonora más disparada por el BCIA fue la de la diástole aumentada y disminuida, de alta necesidad. El promedio del tiempo estímulo-respuesta fue de 33,9 segundos. Conclusión: La gestión de las alarmas de este dispositivo se hace imprescindible para minimizar su fatiga a los pacientes que lo utilizan y para ofrecerles un cuidado más seguro.

Método: Trata-se de um estudo descritivo observacional, com abordagem quanti-qualitativa, do tipo estudo de caso, realizado em uma Unidade de Terapia Cardiointensiva Cirúrgica. Resultados: O alarme sonoro mais disparado pelo BIA foi o de pressão diastólica aumentada-diminuída, de alta prioridade. O tempo estímulo-resposta foi em média de 33,9 segundos. Conclusão: O gerenciamento dos alarmes desses equipamentos torna-se imprescindível para minimizar a ocorrência do fenômeno fadiga de alarmes e na oferta de uma assistência mais segura ao paciente dependente dessa tecnologia.

ABSTRACT

Introduction: Th e ischaemic disorders as a complication of intra-aortic balloon pump counterpulsation (IABP) could be deleterious in critically ill patients with myocardial failure and cardiogenic shock. Th is study is a pilot to predict the length of the descending aorta to select the optimum IABP size for Asian patients. Methods: Th e somatometric features from 80 Chinese patients were used: gender, age, height, body mass index, body surface area, trans-pyloric plane. Moreover, the aortic length from the origin of left subclavian artery to the orifi ce of the celiac trunk (LSA-CT) measured from tomographic scan examination. Th e variables to predict the length from the LSA-CT were studied in four types of predictive statistical analysis: nonlinear regression analysis, tree model, linear regression, and log_linear regression. Th e model was defi ned by obtaining the R square. Results: Th ere were 59 males (mean age 53.9 years SD 13.2, height 170.8cm SD 4.0) and 21 females (mean age 58.7 years SD 7.8, height 160.2 cm SD 6.8). LSA-CT distance was found to be 279.5 SD 31.34 mm. Th e length of distance from the jugular notch to trans-pyloric plane was 273.8cm SD 12.5. Th e body mass index was 25.6 Kg/m2 SD 3.8 and the body surface area 1.8 m2 SD 0.1. Th e tree model for predicting the distance to the left subclavian artery to the celiac axis was chosen due to obtained an R2 square of 0,829. Th e comparison between the tomographic values and results of the tree model was realized with a nonparametric test. Wilcoxon signed-rank test showed that the values of computed tomograhy scan did not show a statistically signifi cant diff erence with the results of the tree model (Z = -0.827 p =0.408). Conclusion: Th e tree model for predicting the distance from the left subclavian artery to the celiac trunk, could be an accurate guide to choosing an adequate catheter length of intra-aortic balloon pump counterpulsation in Asian patients.

ABSTRACT

This pictorial review provides the principles of extracorporeal membrane oxygenation (ECMO) support and associated CT imaging features with emphasis on the hemodynamic changes and possible imaging pitfalls encountered. It is important that radiologists in ECMO centers apply well-designed imaging protocols and familiarize themselves with post-contrast CT imaging findings in patients on ECMO.

ABSTRACT

Trombocitopenia é um achado frequente em unidades de terapia intensiva cardiológica; neste ambiente onde grande parte do arsenal terapêutico diminui a coagulabilidade sanguínea, a baixa contagem plaquetária representa um desafio ao médico intensivista. Este relato de caso ocorreu no Hospital Johns Hopkins, em Baltimore(EUA), em 2003, quando o autor esteve em visita a esta instituição. É apresentada uma revisão da literatura e uma breve discussão do caso

ABSTRACT

O presente trabalho tem por finalidade apresentar as etapas de um projeto para construçao de uma bomba-balao para contrapulsaçao aórtica. Desenvolveram-se três protótipos, sendo que os dois primeiros utilizavam ar comprimido e vácuo hospitalares para insuflaçao e deflaçao do cateter-balao. Esses dois protótipos apresentavam como diferenças fundamentais: o tipo de dispositivo que captava o sinal luminoso da onda R do ECG utilizado para a sincronizaçao do bombeamento; o tipo de válvula solenóide e os componentes eletrônicos de maior resoluçao utilizados no segundo protótipo. O terceiro e atual protótipo passou a obter o sinal da onda R diretamente da saída de cardioversao do monitor de ECG e substituiu o ar comprimia e o vácuo hospitalares, além das válvulas solenóides, por uma bomba eletromagnética. Está em fase de resoluçao o problema de deflaçao tardia que ainda ocorre no sistema.
