Improving rehabilitation after critical illness through outpatient physiotherapy classes and essential amino acid...

Patients recovering from critical illness may be left with significant muscle mass loss. This study aimed to evaluate whether a 6-week program of enhanced physiotherapy and structured exercise (PEPSE) and an essential amino acid supplement drink (glutamine and essential amino acid mixture [GEAA]) improves physical and psychological recovery.

Intensive care patients aged 45 years or older, with a combined intensive care unit stay/pre-intensive care unit stay of 5 days or more were recruited to a randomized controlled trial examining the effect of PEPSE and GEAA on recovery. The 2 factors were tested in a 2 × 2 factorial design: (1) GEAA drink twice daily for 3 months and (2) 6-week PEPSE in first 3 months. Primary efficacy outcome was an improvement in the 6-minute walking test at 3 months.

A total of 93 patients were randomized to the study. Patients receiving the PEPSE and GEA had the biggest gains in distance walked in 6-minute walking test (P < .0001). There were also significant reductions in rates of anxiety in study groups control supplement/PEPSE (P = .047) and GEAA supplement/PEPSE (P = .036) and for GEAA supplement/PEPSE in depression (P = .0009).

Enhanced rehabilitation combined with GEAA supplement may enhance physical recovery and reduce anxiety and depression.
