Incidence of early diaphragmatic dysfunction after lung transplantation: results of a prospective observational study.

Background: Diaphragmatic dysfunction is common after cardiothoracic surgery, but few studies report its incidence and consequences after lung transplantation. We aimed to estimate the incidence of diaphragmatic dysfunction using ultrasound in lung transplant patients up to 3 months postoperatively and evaluated the impact on clinical outcomes.

Methods: This was a single-center prospective observational cohort study of 27 lung transplant recipients using diaphragmatic ultrasound preoperatively, at 1 day, 1 week, 1 month, and 3 months postoperatively.

Commencing Out-of-Bed Rehabilitation in Critical Care-What Influences Clinical Decision-Making?

Objectives: To develop a decision tree that objectively identifies the most discriminative variables in the decision to provide out-of-bed rehabilitation, measure the effect of this decision and to identify the factors that intensive care unit (ICU) practitioners think most influential in that clinical decision.

Design: A prospective 3-part study: (1) consensus identification of influential factors in mobilization via survey; (2) development of an early rehabilitation decision tree; (3) measurement of practitioner mobilization decision-making. Treating practitioners of patients expected to stay >96 hours were asked if they would provide out-of-bed rehabilitation and rank factors that influenced this decision from an a priori defined list developed from a literature review and expert consultation.
