Outcomes

Twyman (1997)
USA
RCT
PEDro=3
N=21

 

Population: Head injury; Time Post-Injury= <72h.
Treatment: Patients were randomly assigned to receive either tube feeding containing 1g nitrogen/150 cal (control group; n=11) or 1g nitrogen/90 cal (study group; n=10).
Outcome Measure: Nitrogen Balance, calorie intake.

  1. Patients receiving the high-protein tube feeding attained a significantly greater daily (p=0.006) and cumulative (p=0.04) nitrogen balance despite higher nitrogen excretions, suggesting high nitrogen feedings are required to replace high nitrogen losses following injury.
  2. Both groups of patients received similar amounts of calories/kg.

PEDro = Physiotherapy Evidence Database rating scale score (Moseley et al., 2002).
