BODY METABOLIC RESPONSE

The Phases of Metabolic Response


1.3 The early phase is also known as Low Flow Phase (Ebb phase) and it occurs immediately after the injury and lasts for 24 hours.
We see a fall in metabolic functions, decrease in body temperature and increase in the levels of stress hormones cortisol,
Epinephrine,
And aldosterone.

1.4 This phase is followed by a Flow phase where the body temperature
and metabolic function rises
There is an increased insulin level, glucose and blood lactate.
With the efficient resuscitative measures the second phase (flow phase) can be brought in earlier.
This is the hyper-metabolic phase and is manifested by an upward
shift in temperature control centre and is a part of the response
to trauma.
Individuals vary in their response to trauma; two important factors are severity of trauma,
And nutritional status of the patient.
Infection also prolongs this phase.
This is the catabolic phase (break down) this phase is because of hypo-volume (loss of blood or fluid) seen in trauma and reduced tissue perfusion, and tends to conserve the bodies resources.


1.5 Anabolic phase.
This is the phase that follows the first two phases and is the phase of rebuilding of the loss resulting from the injury.

This is also called convalescence.
The patient feels better and puts on weight in well treated patients. It starts from 2nd to 10 day onwards.
The hormones required in this phase are insulin and growth
hormone.
