When should fluid resuscitation be discontinued during treatment?

Fluid resuscitation should be discontinued when radial pulses return or blood pressure exceeds 100 mmHg, as this indicates that there is sufficient perfusion to vital organs and tissues. The primary goal of fluid resuscitation in a combat casualty is to restore hemodynamic stability by improving circulation and ensuring the delivery of oxygen to tissues. The return of radial pulses suggests improved circulation and adequate blood volume, while a blood pressure exceeding 100 mmHg indicates that the casualty is not experiencing severe hypotension.

This threshold is vital to monitor because continuing fluid resuscitation beyond this point can lead to complications such as fluid overload, which could impede patient recovery and increase the risk of respiratory distress or other issues. Therefore, recognizing these clinical signs is crucial in the management of casualties during tactical combat situations.
