Brief summary describing the background
and objectives of the trial

The occurrence of muscle weakness and malnutrition are two significant challenges in critical care settings, with an estimated prevalence of 30-50% during hospital stays. Critical conditions, such as Intensive Care Unit -acquired weakness (ICU-AW) and ICU-acquired diaphragm dysfunction (ICU-DD), frequently manifest in critically ill patients undergoing mechanical ventilation, influencing clinical outcomes. ICU-AW is a multifactorial disorder, attributed to factors like drug side effects, disruption of microcirculation, and muscle atrophy from prolonged immobilization. Catabolic processes, particularly myosin catabolism, contribute to muscle mass loss, exacerbating the situation.
The metabolic responses to injury, including a pronounced catabolic response in critically ill patients, result in significant inflammatory and stress reactions, leading to the loss of lean body mass, muscular weakness, tachycardia, and diminished energy. Static responses, such as muscular atrophy, further impact outcomes, including increased mortality and extended hospital stays. To address ICU-AW, novel treatment strategies emphasize early mobilization, reduced sedation, and improved nutrition. Anabolic support during the recovery stage, including testosterone therapy, has been proposed. Testosterone deficiency is common in critically ill patients, indicating a hormonal imbalance during acute illness. While testosterone therapy in healthy males has demonstrated benefits in physical functioning, including increased fat-free mass and muscle strength, it poses virializing side effects for women and adverse impacts on cholesterol levels . Other anabolic agents, such as Decadurabolin and oxandrolone, exhibit more significant effects on muscle strength with minimal androgenic effects.
Few studies investigated the potential benefits of intramuscular Decadurabolin administration on the muscle thickness and strength .Some studies reported that intramuscular Decadurabolin administration increased the muscle thickness and strength and other studies denied this, so we designed this study to judge the effect of intramuscular Decadurabolin administration on muscle weakness in critically ill patients. |
