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).

Nursing workload in intensive care unit trauma patients: analysis of associated factors.

Background: From the perspective of nurses, trauma patients in the Intensive Care Unit (ICU) demand a high degree of nursing workload due to hemodynamic instability and the severity of trauma injuries. This study aims to identify the factors related to the high nursing workload required for trauma victims admitted to the ICU.

Methods: This is a prospective, cross-sectional study using descriptive and correlation analyses, conducted with 200 trauma patients admitted to an ICU in the city of São Paulo, Brazil.

The role of the New Trauma and Injury Severity Score (NTRISS) for survival prediction.

The objective of this study was to verify if replacing the Injury Severity Score (ISS) by the New Injury Severity Score (NISS) in the original Trauma and Injury Severity Score (TRISS) form would improve the survival rate estimation. This retrospective study was performed in a level I trauma center during one year. ROC curve was used to identify the best indicator (TRISS or NTRISS) for survival probability prediction.

Standard examination system for laparoscopy in penetrating abdominal trauma.

Background: The high missed occult small bowel injuries (SBI) associated with laparoscopy in trauma (LIT) is a major reason why some surgeons still preclude LIT today. No standardized laparoscopic examination for evaluation of the peritoneal cavity is described for trauma. The objective of this article is to verify if a systematic standardized laparoscopic approach could correctly identify SBI in the peritoneal cavity for penetrating abdominal trauma (PAT).

Acute care surgeon South American model.

Background: In the World Health Organization book by Murray and Lopez (The Global Burden of Disease), the authors make the point that there are major regional differences across the world for death from injury. In the European market economies, injuries accounted for 6% of all deaths, of which the majority were the result of road traffic accidents. In stark contrast, in Latin America and the Caribbean, injuries account for 12-13% of all deaths, and most of these are the result of violence.

Gut ischemia/reperfusion induced acute lung injury is an alveolar macrophage dependent event.

Background: Although the role of the lung alveolar macrophage (AM) as a mediator of acute lung injury (ALI) after lung ischemia/reperfusion (I/R) has been suggested by animal experiments, it has not been determined whether AMs mediate ALI after intestinal I/R. The objective of this study was to determine the effect of AM elimination on ALI after intestinal I/R in rats.

Methods: Male Wistar rats (n = 90) were randomly divided into three groups: the clodronate-liposomes (CLOD-LIP) group received intratracheal treatment with CLOD-LIP; the liposomes (LIP) group received intratracheal treatment with LIP; and the nontreated (UNTREAT) group received no treatment.

Comparison of anterior gastric wall and greater gastric curvature invaginations for weight loss in rats.

Background: Many bariatric endoscopic or surgical procedures performed today reduce gastric capacity and/or induce an early sensation of gastric satiety, alone or in combination with a distal enteric intervention. A form of prosthetic wrap of the folded stomach was used in the past for treating obesity with a high rate of prosthesis-related reintervention. Nissen gastric fundoplication used in the treatment of gastroesophageal reflux disease induces a small but significant weight loss without gastric stapling, partitioning, or prosthesis-related morbidity.

Evaluation of the mortality rate caused by different periods of selective portal vein occlusion in rats.

Unlabelled: Mortality from acute selective portal vein occlusion (SPVO) is a matter of concern for surgeons during the management of traumatic portal vein injury. However, mortality rates related to different periods of SPVO remains undetermined.

Purpose: To determine the mortality rates resulting from different periods of acute SPVO in rats.

Obstructive jaundice induces early depression of mitochondrial respiration in rat hepatocytes.

Introduction: Oxidative phosphorylation dysfunction of hepatocyte mitochondria is involved in the pathophysiology of organ dysfunction following obstructive jaundice (OJ). However the time period from biliary occlusion to the occurrence of the dysfunction has not been determined decisively.

Purpose: To evaluate the early effects (1 d and 7 d) of OJ on liver mitochondria respiratory function in rats.

Isolated right atrial appendage (RAA) rupture in blunt trauma--a case report and an anatomic study comparing RAA and right atrium (RA) wall thickness.

Background: Heart chambers rupture in blunt trauma is uncommon and is associated with a high mortality. The determinant factors, and the incidence of isolated heart chambers rupture remains undetermined. Isolated rupture of the right atrium appendage (RAA) is very rare, with 8 cases reported in the reviewed literature.

An experimental model for the treatment of lethal bleeding injury to the juxtahepatic vena cava with stent graft.

Background: Juxtahepatic vein injuries present a high mortality rate. Our objectives were to develop an experimental model of endovascular lethal injury of the juxtahepatic inferior vena cava (JHIVC) and to evaluate its hemodynamic alterations; to treat the lesion with volume replacement, and a stent graft (SG); and to follow the animals after treatment.

Methods: Twenty dogs were anesthetized and monitored [heart rate (HR), mean arterial pressure (MAP), vesical and peritoneal pressures], and submitted to a JHIVC endovascular injury.

Intestinal ischemia/reperfusion induces bronchial hyperreactivity and increases serum TNF-alpha in rats.

Introduction: Intestinal or hepatic ischemia/reperfusion induces acute lung injury in animal models of multiple organ failure. Tumor necrosis factor (TNF)- alpha is involved in the underlying inflammatory mechanism of acute respiratory distress syndrome. Although the inflammatory cascade leading to acute respiratory distress syndrome has been extensively investigated, the mechanical components of acute respiratory distress syndrome are not fully understood.

Evaluation of gastric greater curvature invagination for weight loss in rats.

Background: Many bariatric endocopic or surgical procedures performed today reduce gastric capacity and/or induce an early sensation of satiety, alone or in combination with a distal enteric intervention. A form of prosthetic gastric wrap was used in the past for treating obesity with a high rate of reintervention. Nissen gastric fundoplication used in the treatment of gastroesophageal reflux disease induces a small but significant weight loss.

Bile duct-duodenal fistula caused by AIDS/HIV-associated tuberculosis.

Although infrequent, digestive fistulae in HIV/AIDS patients have been reported throughout the digestive tract from the esophagus to the anus, with predominance of esophageal fistulae. AIDS/HIV-associated opportunistic infections may invade the digestive system and lead to fistula formation. Tuberculosis is the most common infection associated with these esophageal fistulae.

Hypertonic saline improves tissue oxygenation and reduces systemic and pulmonary inflammatory response caused by hemorrhagic shock.

Background: The treatment of hemorrhagic shock (HeS) with large volumes of fluid does not ensure an adequate peripheral perfusion or prevent inflammatory activation despite hemodynamic recovery. The purpose of this study was to compare the effect of hypertonic saline (HTS) and isotonic saline (IS) solutions on oxygenation, perfusion, tumor necrosis factor-alpha and interleukin-6 levels, accumulation of polymorphonuclear neutrophils, and pulmonary perivascular edema in the treatment of controlled HeS in rats.

Methods: Wistar rats submitted to HeS for 50 minutes (mean arterial pressure, 45-50 mm Hg) were treated with IS at three times the bled volume or with 5 mL/kg HTS.
