    ABSTRACT: Segment-oriented liver resections can be performed effective by posterior intrahepatic approach. A significance of such resection - is that they are oncologically radical as well as parenchyma-sparing. Segmental liver resections were performed in 102 patients with liver tumors. Suprahilar control of the appropriate glissonean pedicle was achieved by the posterior intrahepatic approach. Liver parenchyma was transsected by ultrasonic dissector, under intermittent vascular occlusion (IVO). Pedicle was divided at the end of resection using "endo-GIA" vascular stapler. The overall transection time was 30,14+/-12,56 min. The amount of blood loss was 285,59+/-129,92 ml. The postoperative complication rate was 25,49%. R0 resection had 94 (92,16%) patients.There was no liver failure or perioperative death. Posterior intrahepatic approach for segmental resection is safe, can expedite the liver transection and reduce intraoperative hemorrhage. This approach provides adequate tumor clearance with preservation of normal parenchyma, as well as the vasculature or the biliary drainage of the contralateral liver.

    ABSTRACT: Neurotrauma is a leading cause of childhood mortality. Physicians are in a continuous search for means to decrease mortality and morbidity caused by head injury. Treatment of these patients requires familiarity with both cerebral pathophysiology and actions of anaesthetic agents on brain. Early treatment of hypotension and hypoventilation would cut mortality rate by at least one third. Prevention of increased intracranial pressure is the best treatment for head injury. Anaesthetist, neurosurgeon and radiologist should all be members of a team which can secure timely diagnosis and treatment of an injured child. Paying attention to every detail is of huge significance. Treatment of the child in a pediatric trauma center or an accident and emergencies center for adults with both personnel and equipment capable for handling paediatric patients offers greater probability of survival.

    ABSTRACT: Intra-abdominal compartment syndrome (ACS) are increasingly recognised to be a contributing cause of organ dysfunction and mortality in critically ill patients. The term abdominal compartment syndrome (ACS) describes the clinical manifestations of the pathologic elevation of the intra abdominal pressure (IAP). This syndrome is most commonly observed in the setting of severe abdominal trauma. ACS affects mainly the respiratory, cardiovascular, renal, gastrointestinal and central nervous system. Preventing ACS by the identification of patients at risk and early diagnosis is paramount to its successful management. Because of the frequency of this condition, routine measurement of intra abdominal pressure should be performed in high risk patients in the intensive care unit. Surgical decompression is definitive treatment of fully developed abdominal compartment syndrome, but nonsurgical measures can often effectively affect lesser degrees of IAH and ACS.

    ABSTRACT: 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 %).

    ABSTRACT: 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.

    ABSTRACT: Injuries of the stomach and duodenum have an important place in abdominal trauma, even though that the isolated injuries are rare. This kind of injury is most commonly associated with injuries of other abdominal organs. This retrospective study has been done at the Department of Emergency Surgery, Clinical Centre of Serbia, during the period from January 2004. until January 2009. The study included 36 patients diagnosed intraoperatively with the injury of the stomach and duodenum. The most common mechanism of harming were injuries due to blunt trauma (41.7%), the ones followed by gunshot wounds (30.5%), and the least were stab injuries (27.8%). With the majority of patients has been conducted sutures (46.3%) and serosation (30.6%) of the stomach and duodenum. In 24 (66.7%) patients on admission have been done ultrasound of the abdomen, in 6 (16.7%) abdominal CT was done, in 4 (11.1%) peritoneal lavage have been done and the x-ray of the abdomen was performed in 3 (8.3%) patients. Specific complications had 1 (2.8%) patient, while 14 (29.9%) patients have had non-specific complications. Total mortality has been 33.3%

    ABSTRACT: Nosocomial infections (NI) are significant medical problem in the countries worldwide. NI significance reflects in higher morbidity and mortality rates, and moreover, NIs add to longer stay and higher treatment costs. Based on data obtained from underdeveloped and developing countries, over 20% of hospitalized patients acquire some of NIs, while that proportion is 5% in developed countries. A) to establish the frequency of noosocomial infections at the Clinic of Digestive System Diseases, b) determine the NI incidence in accord with anatomic localizations, c) evaluate the percentage prevalence of NI causes according to anatomic localizations, and d) review the problem of resistance of NI causative agents. The study of NI incidence was calculated by Center for Diseases and Prevention (CDC) methodology. Sampling, cultivation, isolation, identification and sensitivity tests of cauosative agents to antimicrobial drugs, obtained from patient's material, were carried out by standard microbiological methods in Microbiological laboratory of the Emergency Center, Clinical Center of Serbia. All infections in patients hospitalized at the Clinic of Digestive System Surgery in 2007 were recorded. Data available from medical documentation as well as data obtained from interviews of medical personnel were analyzed. The incidence rates of patients with NI ranged from 1.7-3.4 per 1000 hospital days. Out of a total number of recorded nosocomial infections, surgical site infections accounted for 69%, blood infections 23% and urinary tract infections 6.8%. The most frequent causative agents of surgical site infections in the last year were as follows: Pseudomonas spp (19%), followed by Staphylococcus aureus and Klebsiella spp--(18%), Acinetobacter spp (13%), and Enterococcus spp (8%). Forty percent (40%) of all blood infections verified by laboratory tests in 2007 was caused by coagulase negative Staphylococcus spp (CNS), followed by Acinetobacter spp (18%). Enterococcus spp (11%), and Staphylococcus aureus (7%). The most frequent causative agents of urinary infections were: Escherichia coli (35%) and Enterococcus spp (29%). Over 80% of Staphylococcus aureus isolates were resistant to Methicillin (MRSA) and enterobacteria produced by beta lactamase were recorded (ESBL). Enforcement of epidemiological surveillance of nosocomial infections contributes to insight of severity of NI problem, recognition of resistance of causative agents to antibiotics and recommendation of specific preventive measures related to these infections.

    ABSTRACT: To determine overall mortality and timing of death in patients with severe acute pancreatitis and factors affecting mortality. This was a retrospective, observational study of 110 patients admitted to a general intensive care unit (ICU) from January 2003 to January 2006. The overall mortality rate was 53.6% (59/110); 25.4% (n = 15) of deaths were early (<or=14 days after ICU admission). There were no significant differences in age, sex, or surgical/medical treatment between survivors and nonsurvivors. Median Acute Physiology and Chronic Health Evaluation (APACHE) II score was higher among nonsurvivors than survivors (score = 26 vs 19, respectively; P < 0.001), and the duration of hospitalization before ICU admission was significantly longer (4 vs 1 day; P < 0.001). Among the 59 patients who died, those in the early-mortality group were admitted to the ICU significantly earlier than those in the late-mortality group (3 vs 6.5 days; P < 0.05). Overall mortality and median APACHE II score were high. Death predominantly occurred late and was unaffected by patient age, length of stay in the ICU, or surgical/medical treatment. An APACHE II cutoff of 24.5 and pre-ICU admission time of 2.5 days were sensitive predictors of fatal outcome.

    ABSTRACT: Because the supply of cadaveric organ donors is limited and their ICU management is complex, a multidisciplinary, well-coordinated, and institutionally supported approach to management is essential to ensure the maintenance of the current supply and to increase the future supply of organs and tissues that are suitable for transplantation. The potential organ donor is at high risk for instability as a direct consequence of the loss of physiologic homeostatic mechanisms that are dependent on functioning of the central nervous system. The keys to successful ICU management of the potential organ donor include a team approach that is focused on the anticipation of complications, appropriate physiologic monitoring, aggressive life support, with frequent reassessment and titration of therapy.

    ABSTRACT: Hemorrhagic shock is a condition produced by rapid and significant loss of blood which lead to hemodynamic instability, decreases in oxygen delivery, decreased tissue perfusion, cellular hypoxia, organ damage and can be rapidly fatal. Despite improved understanding of the pathophysiology and significant advances in technology, it remains a serious problem associated with high morbidity and mortality. Early treatment is essential but is hampered by the fact that signs and symptoms of shock appear only after the state of shock is well establish and the compensatory mechanisms have started to fail. The primary goal is to stop the bleeding and restore the intravascular volume. This review addresses the pathophysiology and treatment of haemorrhagic shock.

    ABSTRACT: Massive hemorrhage is a formidable challenge for anesthesia care providers in the elective setting and poses even greater potential challenges in the trauma setting. In all this cases, the anesthesia care providers are faced with large-volume resuscitations that typically start with crystalloid and colloid and rapidly progress to blood and blood products. These large-volume replacement may cause coagulopathy, which can be difficult to manage in the setting of ongoing blood loss. Coagulopathy associated with massive transfusion is multifactorial event that results from hemodilution, hypothermia, the use of fractionated blood products and disseminated intravascular coagulation. Maintaining a normal body temperature is a first-line, effective strategy to improve hemostasis during massive transfusion. Treatment strategies include the maintenance of adequate tissue perfusion, the corection of anemia, and the use of hemostatic blood products.
