Functional capacity assessment of patients under mechanical ventilation in Intensive Care Unit/ Avaliacao da capacidade funcional dos pacientes em uso de ventilacao mecanica internados em uma Unidade de Terapia Intensiva/Evaluacion de la capacidad funcional de la ventilacion mecanica en pacientes ingresados en Unidad de Terapia Intensiva

Introduction: Physical limitations due to immobilism experimented by adult patients under mechanic ventilation (MV) in intensive care unit (ICU) is not usually measured systematically with functional scales. Objectives: To describe the evolution of functional capacity using the Perme Scale, as well as peripheral and respiratory muscle strength of patients under MV in the ICU of a university hospital. Methods: From august to december 2016, we observed all patients admitted in the ICU. Patients were included only when submitted to MV. The four different moments of hospitalization that assessments were done in the ICU: admission in the ICU (A1), the first day of MV (A2), weaning of MV (A3) and discharge of the ICU (A4). We evaluated functional capacity using Perme Scale and muscular strenght assessments using the medical research council scale, PImax and PEmax. We used the Katz Index at the time of admission to measure functional capacity before hospitalization. Results: We included 26 patients and 9 completed the four evaluations. The median of age, Katz Index and SAPS III was 63 years (58-70), 6 (5-6) and 64 (44.75 - 68.50), respectively. There was a progressive improvement in the MRC, PImax and PEmax values throughout the evaluations. On the Perme Scale there was an increase from 2 (1,5-7,25) in A1 to 10 (6,75-22) in A4. Conclusions: In these patients, the muscle strength and functional capacity increased during de hospitalization in the ICU. The Perme Scale was not applicable for all moments.

Introducao: Limitacoes fisicas e psicologicas decorrentes do repouso prolongado no leito sao complicacoes comumente encontradas no paciente critico e impactam diretamente na capacidade funcional. Objetivos: Avaliar a evolucao da capacidade funcional, da forca muscular periferica e respiratoria de pacientes ventilados mecanicamente internados no CTI Geral do Hospital Universitario Pedro Ernesto (HUPE). Metodologia: No periodo de dezembro de 2016 a fevereiro de 2017 observamos os pacientes admitidos no CTI. Pacientes que nao evoluiram para ventilacao mecanica (VM) foram excluidos. Os pacientes foram avaliados em quatro momentos: admissao no CTI geral (A1), primeiro dia de VM (A2), desmame da VM (A3) e alta do CTI (A4). Avaliamos a forca muscular respiratoria periferica, respiratoria e a capacidade funcional atraves da Escala Perme. Avaliamos a funcio
