Application of the ICU Mobility Scale in patients submitted to cardiac surgery / Aplicação da ICU Mobility Scale em pacientes submetidos à cirurgia cardíaca

Abstract Introduction Early mobilization is an alternative used in the Intensive Care Unit (ICU) to reduce the effects of immobility. The Intensive Care Unit Mobility Score (IMS) is applied to assess mobility status. Objective To determine the functional level of ICU patients submitted to cardiac surgery using the IMS scale. Methods This is an analytical observational study carried out with adult ICU patients submitted to cardiac surgery. Data on the use of vasoactive drugs, functional level through IMS, duration of mechanical ventilation and length of ICU stay were collected from the physiotherapy routine form and recorded on a specific instrument developed for the study. The data obtained from the IMS scale score on the postoperative days in the ICU were used to classify the patients' mobility during the hospitalization period. Descriptive statistics were used to present the data. Results A total of 69 patients were evaluated, 43% of whom were men, and all had an SMI of 0 on the first postoperative day. Classification on the scale increased over the course of hospitalization (IMS between 7 and 10), despite the use of vasoactive drugs in 54.6% of the individuals. Conclusion Patients submitted to cardiac surgery admitted to the ICU had moderate-to-high mobility levels throughout their stay and at discharge from the ICU.

Resumo Introdução A mobilização precoce é uma alternativa utilizada em Unidades de Terapia Intensiva (UTIs) na tentativa de reduzir os efeitos decorrentes do imobilis-mo. A escala de mobilidade em UTIs ou Intensive Care Unit Mobility Score (IMS) é aplicada para avaliar o nível de mobilidade. Objetivo Verificar por meio da escala IMS o nível de funcionalidade de pacientes submetidos à cirurgia cardíaca internados em uma UTI. Métodos Trata-se de um estudo observacional analítico realizado em UTI com pacientes adultos submetidos à cirurgia car-díaca. Foram coletados da ficha de rotina da fisioterapia informações quanto ao uso de drogas vasoativas, nível funcional por meio da IMS, tempo de ventilação mecânica e de internação na UTI, e registrados em instrumento específico desenvolvido para o estudo. Os dados obtidos do escore da escala IMS nos dias de pós-operatório na UTI foram utilizados para classificar a mobilidade dos pacientes durante o período de internação. Utilizou-se estatística descritiva para a apresentação dos dados. Resultados Foram avaliados 69 pacientes, 43% eram do sexo masculino e todos apresentavam IMS 0 no primeiro dia de pós-operatório. A classificação na escala aumentou com o decorrer do período de internação (IMS entre 7 e 10), apesar do uso de drogas vasoativas em 54,6%. Conclusão Os pacientes submetidos à cirurgia cardíaca internados na UTI apresentaram níveis de mobilidade de moderado a alto ao longo da internação e na alta da UTI.

Early Mobilization Prescription in Patients Undergoing Cardiac Surgery: Systematic Review

ABSTRACT Introduction: Early mobilization of patients in the postoperative period of cardiac surgery who are hospitalized in the intensive care unit (ICU) is a practice that has a positive impact. Methods: This is a systematic review of studies published until September 2020 in the Medical Literature Analysis and Retrieval System Online (or MEDLINE®), Embase, Physiotherapy Evidence Database (or PEDro), Scientific Electronic Library Online (or SciELO), and Latin American and Caribbean Health Sciences Literature (or LILACS) databases. Randomized clinical trials describing mobilization protocols performed early in ICU patients after cardiac surgery were included. Results: According to the eligibility criteria, only 14 of the 1,128 articles found were included in the analysis. Early mobilization protocols were initiated in the immediate postoperative period or first postoperative day. The resources and technics used were progressive mobilization, cycle ergometer, early bed activities, walking protocols, resistance exercise, and virtual reality. Intensity of the mobilization activities was determined using the Borg scale and heart rate. Conclusion: Early mobilization protocols are generalist (not individual), and low-intensity exercises are used, through progressive mobilization, with two daily physical therapy sessions, during 10 to 30 minutes.
