The purpose of the paper is to evaluate the duration of trauma resuscitation within the Trauma Resuscitation Area in patients with multiple injuries, and possible time‑saving by introducing a teamwork model. A retrospective evaluation included medical documentation of patients treated in the Emergency Department of Warsaw Military Institute of Medicine in 2015. The calculation covers median value, the first and the third quartile of total activity time of trauma team in the resuscitation area. The second stage included repeated simulation of resuscitation in a trauma room setting, using a CPR manikin. The resuscitation times have been measured for trauma teams of two or three. The results are presented in tabular and descriptive form. Introduction of trauma teamwork model in trauma patient care may shorten resuscitation and increase its efficacy. Regular team training and improvement of communication within the trauma team are key factors that improve quality of the treatment provided.
