Impact of a High-Protein Diet on Clinical Outcomes in Mechanically Ventilated Patients With Severe Pneumonia
Aperçu de l'étude
Statut
Les conditions
Description détaillée
prospective, comparative, observational study will be conducted at the Critical Care Department, Fayoum University Hospital, aims to evaluate the effect of a high-protein diet on clinical outcomes in mechanically ventilated patients with severe pneumonia, focusing on muscle preservation and weaning ability. The specific objectives are:
- To assess the impact of high-protein intake on skeletal muscle mass using quadriceps ultrasound.
- To evaluate diaphragmatic function and thickness in relation to protein intake using ultrasound.
- To determine the effect of high-protein nutrition on weaning success, duration of mechanical ventilation, length of hospital stay and mortality.

Principaux critères de jugement
Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|
|
Duration of mechanical ventilation
Délai: From enrollment to the end of treatment at 1 to 2 weeks
|
The total time in days during which the patient receives invasive mechanical ventilatory support through an endotracheal tube or tracheostomy, calculated from the initiation of mechanical ventilation until successful liberation from the ventilator or death.
|
From enrollment to the end of treatment at 1 to 2 weeks
|
|
Weaning Success
Délai: 1 to 2 weeks
|
Successful discontinuation of mechanical ventilatory support with maintenance of spontaneous breathing after extubation, without the need for re-intubation, reinstitution of invasive mechanical ventilation, or death within 48 hours.
|
1 to 2 weeks
|

Preservation of Quadriceps Muscle Mass Assessed by Ultrasound
Délai: 2 weeks
|
Preservation of quadriceps muscle mass was assessed using bedside ultrasonography by measuring the quadriceps muscle thickness at predefined anatomical landmarks.
Muscle preservation was defined as the percentage change in muscle thickness from baseline to the follow-up assessment, with a smaller reduction indicating better preservation of muscle mass.
|
2 weeks
|
|
Diaphragm Muscle Thickness Assessed by Ultrasound
Délai: 2 weeks
|
Diaphragm muscle thickness was assessed using bedside ultrasonography in the zone of apposition of the diaphragm. The thickness of the diaphragm measured by ultrasound at the zone of apposition, expressed in millimeters (mm). Measurements were obtained at end-expiration, and the percentage change from baseline was used to assess diaphragm muscle preservation or atrophy. Diaphragm Thickening Fraction (DTF) (%)=(DT at end-inspiration - DT at end-expiration) ÷ DT at end-expiration × 100. TF ≥ 20% is considered normal; < 20% suggests diaphragmatic dysfunction. |
2 weeks
|
|
Incidence of ICU-Acquired Weakness
Délai: 1 to 4 weeks
|
The percentage of patients who develop ICU-acquired weakness during ICU admission.
ICU-AW was diagnosed when the MRC sum score was <48/60 during ICU admission.
|
1 to 4 weeks
|
|
ICU Length of Stay
Délai: 2 to 4 weeks
|
The number of days spent in the ICU, calculated from ICU admission to ICU discharge, transfer to another ward, or death during ICU stay.
|
2 to 4 weeks
|
|
Mortality
Délai: 2 to 4 weeks
|
The proportion of patients who die during their ICU stay, calculated from ICU admission until ICU discharge.
|
2 to 4 weeks
