Predictive factors of mortality in patients with pelvic fracture and shock submitted to extraperitoneal pelvic packing.

Introduction: in recent decades, the extraperitoneal pelvic packing technique has been disseminated, but there are still few studies. Thus, it was decided to analyze the results of extraperitoneal pelvic tamponade, in patients with pelvic fracture and shock, in order to identify predictive factors for mortality.

Methods: a retrospective review of medical records of patients submitted to extraperitoneal pelvic packing was conduced.

Efficacy of a Novel Surgical Manikin for Simulating Emergency Surgical Procedures.

The practical component of the Advanced Trauma Life Support (ATLS®) course typically includes a TraumaMan® manikin. This manikin is expensive; hence, a low-cost alternative (SurgeMan®) was developed in Brazil. Our primary objective was to compare user satisfaction among SurgeMan, TraumaMan, and porcine models during the course.

New Trauma and Injury Severity Score (TRISS) adjustments for survival prediction.

Background: The objective of this study is to propose three new adjustments to the Trauma and Injury Severity Score (TRISS) equation and compare their performances with the original TRISS as well as this index with coefficients adjusted for the study population.

Methods: This multicenter, retrospective study evaluated trauma victims admitted to two hospitals in São Paulo-Brazil and San Diego-EUA between January 1st, 2006, and December 31st, 2010. The proposed models included a New Trauma and Injury Severity Score (NTRISS)-like model that included Best Motor Response (BMR), systolic blood pressure (SBP), New Injury Severity Score (NISS), and age variables; a TRISS peripheral oxygen saturation (SpO) model that included Glasgow Coma Scale (GCS), SBP, SpO, Injury Severity Score, and age variables; and a NTRISS-like SpO model that included BMR, SBP, SpO, NISS, and age variables.

Performance of new adjustments to the TRISS equation model in developed and developing countries.

Background: The Trauma and Injury Severity Score (TRISS) has been criticized for being based on data from the USA and Canada-high-income countries-and therefore, it may not be applicable to low-income and middle-income countries. The present study evaluated the accuracy of three adjustments to the TRISS equation model (NTRISS-like; TRISS SpO; NTRISS-like SpO) in a high-income and a middle-income country to compare their performance when derived and applied to different groups.

Methods: This was a retrospective study of trauma patients admitted to two institutions: a university medical center in São Paulo, Brazil (a middle-income country), and a level 1 university trauma center in San Diego, USA (a high-income country).
