Introduction: The hospital environment exacerbates the effects of immobility due to several exposure factors, and the functional assessment of individuals using reliable instruments is vital. Objective: To determine the relationship between functional mobility and the clinical outcome of patients admitted to an intensive care unit. Method: This is a prospective quantitative longitudinal study, approved by the institutional research ethics committee, carried out in the intensive care unit of a University Hospital. Clinical data and the Acute Physiology and Chronic Health Evaluation (APACHE II) score were collected 24 hours after admission. The Perne Score was used to analyze patient mobility. Results: 33 patients participated, 63% female. With respect to mobility and transfers, 69.7% required total assistance from the supine to the sitting position and 70% to maintain balance, 9.1% needed minimum assistance from sitting to standing, and 100% total assistance for walking and endurance exercises. The main barriers to mobility were invasive ventilation (60%), assistive devices and intravenous infusion (100%). The following Perne Score domains were significantly associated with the outcome: mental status (p = 0.040), barriers to mobility (p = 0.016), strength (p = 0.010), mobility in bed (p = 0.024) and the total Perme Score ( p = 0.002). There were also significant associations between invasive ventilation and low Perme Scores (p = 0.000), and the Richmond Agitation-Sedation Scale (RASS) (-5 and -4) and death in 66.7% of patients (p = 0.011). The Perme Score and RASS (R = 0.745) were moderately correlated and APACHE II and Perme Score inversely moderately correlated (R = -0.526). Conclusion: Mobility assessed by the Perme Score was related to the clinical outcome and strongly associated with sedation level and patient severity.
Objetivo: avaliar os efeitos adversos agudos e conforto da interface máscara de mergulho como estratégia de suporte ventilatório durante a ventilação não invasiva. Metodologia: Estudo clínico, experimental e descritivo, realizado no laboratório da Unidade de Pesquisas Clínicas, da Universidade Federal do Ceará, no período de junho e julho de 2020. Foram estudados 12 voluntários saudáveis. Utilizou-se um modelo de suporte ventilatório não invasivo de circuito único, acoplado a máscara de mergulho, cilindro de ar comprimido (fluxo de 15L/min) e válvula de PEEP (5cmH2O), durante o período de 60 minutos. As variáveis avaliadas foram: parâmetros fisiológicos (frequência cardíaca, frequência respiratória, pressão arterial e saturação periférica de oxigênio), gasometria venosa, escala visual analógica e efeitos adversos relacionados a interface. Resultados: A amostra foi composta por 12 mulheres com idade média 25,58 ± 3,47. Não foi observada diferença estatisticamente significante entre os dados gasométricos quando comparado os valores antes e após o uso da interface. O nível de desconforto respiratório foi pontuado como leve durante o uso da interface. Os efeitos adversos com maior grau de problema foram: pressão da máscara, desconforto torácico, peso da máscara e pressão no ouvido. Conclusão: A interface máscara de mergulho parece ser viável, não apresentando graves níveis de efeitos adversos que inviabilize a sua utilização, porém para ampliar a sua aplicabilidade clínica são necessárias implementações de melhorias.
