RESUMO
Acutelunginjury (ALI) and its more severe form acute respiratory distress syndrome (ARDS) are syndromes with a spectrum of increasing severity of lung injury defined by physiologic and radiographic criteria. There are many clinical disorders as sociated with the development of ALI/ARDS and can be divided into those associated with direct or indirect lung injury. Early detection and protective lung ventilation strategy contribute to lowering the mortality rate.

Anemia is common in critically ill patients and carries risk of reduced oxygen carriage and worse outcomes. Transfusion, however, carry their own risk, and the physician must balance the risks of anemia with the risk of transfusion in each patient. Some recent studies compared a liberal with a restrictive approach to transfusion, and a clinical practice guidelines were made. This protocols consider that acute hemorrhage has been controlled, the initial resuscitation has been completed, and the patient is stabile in the intensive care unit without ongoing bleeding. The trigger for PRBC transfusion in patients without severe cardiovascular disease is hemoglobin g/dL (or a hematocrit %).

Laparoscopic diagnostics provides fast, reliable, clear, and obvious information on extent and depth of abdominal organs injury with minimizing additional trauma to the patient. It is performed without any specific preparations and, if needed, it may be promptly converted into conventional laparotomy. Through use of optical equipment with various refraction angles and through variable patient positioning, laparoscopic technique enables visualization of whole abdominal cavity. In approximately 20% of cases of unclear findings, and after other performed diagnostic procedures, laparoscopy provides definitive diagnosis. Abdominal surgeons are familiar with this method, making interpretaion of the results very fast and reliable and, what is the most important, this method avoids additional trauma caused by conventional laparotomy.

The phylosophy of aggressive surgical approach, its complete implementation in liver trauma surgery did not appear efficient. No matter of permanenent development of diagnostic imaging methods, anesthesia, intensive therapy, medical technology and suture materials, operational theater and operative tchniques, major liver resections in trauma had mortality rate up to 60%. With introduction of computerized tomography (CT, 1981) in everyday clinical praxis and with better evaluation of trauma patients, the whole approach to liver trauma patient has been redesigned. Based on AAST-OIS classification, almost 70% of traumatized with grade I, II and III sholud be treated non-operatively, hospitally, with repeating FAST (focused abdominal ultrasound in trauma) and abdominal CT scans. The rest of traumatized patients, with grade IV and V injuries of juxtahepatic structures demand complexive surgical treatment. The modalities of surgical treatment depend on trauma mechanisms, extensivity, anatomical localisation and affection of vascular structures. Hanging Manuevr--the Method of French surgeon Belghiti bases on anterior approach in liver resection is a try for fast solution for fatal bleeding in liver trauma. It consists of placing the elastic cord throughout the anterior surface of VCI or ligamentum venosusm, of upper end of the cord is located in superior part of VCI where hepatic veins are emerging. Lower end of the cord is located in subhepatic part of VCI between 3 Glisonian pedicles. Concerning hepatic veins liver is divided in 3 sections, which derives blood in right hepatic vein RHV, middle hepatic vein MHV and left hepatic vein LHV. Belghiti proposed the usage of hanging maneuver when resecting the right liver, while the cord is placed throughout retrohepatic VCI, lower end between elements of Glisonian pedicle and upper end between hepatic veins. Complications like bleeding from caudal veins are minimal, then speed in liver resection in hemodynamic unstable and ishemic patient, defects like bleeding because compressing tapes or lesions IVC tile mobilazion of liver for conventional resection.

Question of missed injuries is more often a question of human errors: task execution errors, procedural errors, communication errors, decision errors and noncompliance. Missed injuries are those which are not idetified in the first three days of hospitalisaation. This theme is not popular among physicians. Literature data mention percent from 3-29% missed injuries overall. The underlying causes errors are: false attributin, false negative prediction and false lebeling. False attribution involves a tendency to incorrectly link a clinical observation with an arroneous cause. This tendency also ignores one of the fundamental principles of the management of traumatic injury: that the index of suspicion should proceed on the basis of assumed wors resonable case scenario. Weaknesses of trauma systems: high patients volume, high-risk patients, long hours, changing set of resources, and problems sush bad admission planing, defficite anamnesis, defficite diagnostic procedures, bad communication, improvisation etc.
