The Ebb phase develops within the first hours after injury (24–48 hours) . It is characterized by reconstruction of body’s normal tissue perfusion and efforts to protect homeostasis. In this phase, there is a decrease in total body energy and urinary nitrogen excretion.

The "ebb" phase is associated with a decline in body temperature and oxygen consumption, presumably aimed at reducing posttraumatic energy depletion. The brief duration of this phase limits its clinical relevance.

Jun 14, 2015 · Historically, the response to injury was divided into two phases: ‘ebb’ and ‘flow’. In the ebb phase during the first few hours after injury patients were cold and hypotensive (shocked). When intravenous fluids and blood transfusion became available, this shock was sometimes found to be reversible and in other cases irreversible.

Jun 1, 2024 · It results in a complex response initially described in 1942 as an acute ‘ebb’ phase of catabolism followed by anabolism in the ‘flow phase’. Others have described the process as a ‘nervous’ initial phase, closely followed by an ‘immune’ phase which then develops into a late ‘endocrine’ phase.

The second flow phase, beginning after the ebb phase and lasting for days to weeks depending on injury severity, is characterized by increases in cardiac output, respiratory rate, VO2, hyperglycemica, skeletal muscle catabolism, and a negative nitrogen balance.

Jul 1, 2000 · The terms ‘ebb’ and ‘flow’ were introduced to describe an initial decrease and subsequent increase in metabolic activity. The description of the ‘ebb’ phase was based partly on work in experimental animals and the estimations of increases in metabolic rate in the ‘flow’ phase were exaggerated.

The metabolic response to injury in humans is divided into ‘ebb’ and ‘flow’ phases. The ebb phase begins at the time of injury and lasts for approximately 24–48 hours. It may be attenuated by proper resuscitation, but not completely abolished. Hypothermia and lactic acidosis.

Oct 4, 2006 · The "ebb" phase is initiated within minutes after trauma and persists for several hours after the initial insult. It is characterized by a decline in body temperature and oxygen consumption, aimed at reducing posttraumatic energy depletion.

Jun 18, 2016 · The ebb phase is usually short and may correspond to clinical shock, resulting from reduced tissue perfusion. The physiological changes that occur here are designed to restore adequate vascular volume and maintain essential tissue perfusion. The severity of the ebb phase determines clinical outcome.

Following this early phase (previously described as Ebb phase) a stabilized phase is observed. REE derived from VCO 2 may guide nutritional therapy.
