This chapter reviews a range of tools and approaches for the stabilization of traumatized patients and the containment of eruptions of traumatic material until they can be effectively addressed in a later phase of treatment. The International Society for the Study of Trauma and Dissociation (ISSTD) Treatment Guidelines describe the consensus model in three phases, to include stabilization, trauma metabolization, and integration phases of treatment. Many patients experience continuous swings from one extreme of arousal to the other or have lives characterized by chronic shutdown, punctuated with occasional explosions of high arousal. Consistent with the theory of optimal arousal level, the patient must have the capacity to tolerate somatic sensation and affective awareness in order to process through any channels of information that comprise traumatic memory. Therapy will often need to help establish resources for traumatized patients through basic psychoeducation, an essential feature of preparation for poststabilization trauma reduction work.
