Much controversy exists over the fluid composition for hypotensive resuscitation. We previously showed that addition of 6% Dextran-70 or hetastarch to 7.5% NaCl led to heart instability and mortality. Our aim was to examine the early resuscitative effects of 7.5% NaCl with adenosine, lidocaine, and magnesium (ALM) on hemodynamics and mortality in a rat model of severe hemorrhagic shock. ⋯ Ultra-small intravenous bolus of 7.5% NaCl with ALM led to a significantly higher MAP, higher diastolic rescue, and higher rate-pressure product compared with other treatment groups. The possible clinical and military applications for permissive hypotensive resuscitation are discussed.

Dysautonomia after severe traumatic brain injury (TBI) is a clinical syndrome affecting a subgroup of survivors and is characterized by episodes of autonomic dysregulation and muscle overactivity. The purpose of this study was to determine the incidence of dysautonomia after severe TBI in an intensive care unit setting and analyze the risk factors for developing dysautonomia. ⋯ Dysautonomia frequently occurs in patients with severe TBI. A younger age and DAI could be risk factors for facilitating the development of dysautonomia.

Lumbopelvic distraction stabilization with (triangular osteosynthesis) or without additional iliosacral screw allows anatomic reduction of the posterior pelvic ring after severely displaced sacral fractures, correction or resection osteotomies of malunions, respectively, septic sacroiliitis and permits early weight bearing. However, this technique is complicated by wound necrosis or infection in up to 20% to 30%. We describe our experience with a less invasive technique. ⋯ The presented technique respects the lumbar anatomy and provides the access required for lumbopelvic stabilization, while having the potential to decrease or even prevent postoperative wound disorders if combined with a polyaxial low-profile system. The low number of cases presented may, however, limit the relevance of the conclusions in cases of severe Morell-Lavallé lesions with skin disorders.
