RESUMEN
BACKGROUND: Decisions about limitations of life sustaining treatments (LST) are made for end-of-life patients in intensive care units (ICUs). The aim of this research was to explore the professional and ethical attitudes and experiences of medical professionals on treatment of end-of-life patients in ICUs in the Republic of Croatia. METHODS: A cross-sectional study was conducted among physicians and nurses working in surgical, medical, neurological, and multidisciplinary ICUs in the total of 9 hospitals throughout Croatia using a questionnaire with closed and open type questions. Exploratory factor analysis was conducted to reduce data to a smaller set of summary variables. Mann-Whitney U test was used to analyse the differences between two groups and Kruskal-Wallis tests were used to analyse the differences between more than two groups. RESULTS: Less than third of participants (29.2%) stated they were included in the decision-making process, and physicians are much more included than nurses (p < 0.001). Sixty two percent of participants stated that the decision-making process took place between physicians. Eighteen percent of participants stated that 'do-not-attempt cardiopulmonary resuscitations' orders were frequently made in their ICUs. A decision to withdraw inotropes and antibiotics was frequently made as stated by 22.4% and 19.9% of participants, respectively. Withholding/withdrawing of LST were ethically acceptable to 64.2% of participants. Thirty seven percent of participants thought there was a significant difference between withholding and withdrawing LST from an ethical standpoint. Seventy-nine percent of participants stated that a verbal or written decision made by a capable patient should be respected. Physicians were more inclined to respect patient's wishes then nurses with high school education (p = 0.038). Nurses were more included in the decision-making process in neurological than in surgical, medical, or multidisciplinary ICUs (p < 0.001, p = 0.005, p = 0.023 respectively). Male participants in comparison to female (p = 0.002), and physicians in comparison to nurses with high school and college education (p < 0.001) displayed more liberal attitudes about LST limitation. CONCLUSIONS: DNACPR orders are not commonly made in Croatian ICUs, even though limitations of LST were found ethically acceptable by most of the participants. Attitudes of paternalistic and conservative nature were expected considering Croatia's geographical location in Southern Europe.

Infertility is one of the major medical problems nowadays. Couples who opt for In Vitro Fertilization (IVF) face a great deal of stress which certainly affects the outcome of the procedure. Therefore, we aimed to reduce the stress during the oocyte retrieval procedure by applying midazolam. Total oxidant (TOC) and antioxidant (TAC) capacities of serum, as well as glutathione (GSH) content and catalase activity, were measured in both control and midazolam groups. Follicular fluid was also tested for oxidant capacity and IL1ß. Results implied that the midazolam group increased TAC at the end of the procedure. At the same time, the control group decreased GSH at the beginning of the procedure, and both groups decreased catalase activity at the end of the procedure. The results imply that stress during the procedure affects oxidative and antioxidative parameters of the patients, but did not affect the frequency of the pregnancy at the end of this pilot study. Yet, the results imply that oxidative and antioxidative mechanisms during IVF should be investigated in detail as they could affect the outcome of IVF.
RESUMEN
In 1937, Ugo Cerletti and Lucio Bini performed electroconvulsive treatment (ECT) in Rome for the first time. That was the time when different types of 'shock therapy' were performed; beside ECT, insulin therapies, cardiazol shock therapy, etc. were also performed. In 1938, Cerletti and Bini reported the results of ECT. Since then, this method has spread rapidly to a large number of countries. As early as 1940, just two years after the results of the ECT had been published, it was also introduced in Croatia, at Sestre milosrdnice Hospital, for the first time in our hospital and in the then state of Yugoslavia. Since 1960, again the first in Croatia and the state, we performed ECT in general anesthesia and continued it down to the present, with a single time brake.

Four thousand cardiac implantable electronic devices (CIED) are implanted yearly in Croatia with constant increase. General anesthesia and surgery carry some specific risk for the patients with implanted CIEDs. Since most of the surgical procedures are performed in institutions without reprogramming devices available, or in the periods when they are unavailable, these guidelines aim to standardize the protocol for perioperative management of these patients. With this protocol, most of the procedures can be performed easily and, more importantly, safely in the majority of surgical patients.

BACKGROUND: Maintenance of the open lung alveoli in the expiration on mechanical ventilation in acute lung injury/acute respiratory distress syndrome (ALI/ARDS) remains challenging despite advances in lung imaging. The inspiratory lower inflection point (LIP) on the ventilator pressure-volume (P-V) curve estimates the required end-expiratory pressure for recruitment of alveolar consolidation. Alternatively, the end-expiratory pressure for recruitment of crater-like subpleural alveolar consolidation could be simply followed with ultrasound. These two methods for setting the ventilators positive end-expiratory pressure (PEEP) were compared. METHODS: The observational study in surgical/neurosurgical intensive care between October 2009 and November 2011 included 17 deeply sedated or relaxed patients. LIP was measured with continuous low-flow method, as a pressure in cmH(2)O. Expiratory levelling between lower border of subpleural consolidation and adjacent pleural line, which means lung recruitment, was followed with linear ultrasound probe. PEEP in cmH(2)O at which the levelling occurs was compared with LIP pressure. RESULTS: LIP pressure never exceeds the PEEP for recruitment of subpleural consolidations followed with ultrasound. A significant correlation (r = 0.839; p < 0.05) was found between two methods. CONCLUSIONS: In this study, positive end-expiratory pressures for recruitment of subpleural consolidations followed by ultrasound always exceed the pressures measured with LIP. Respecting this, ultrasound method could be the guide for PEEP lung recruitment.

Difficult airway has gained increasing interest due to a relatively high number of adverse effects following unsuccessful intubation. Besides traditional techniques, several alternative methods are available today. It is crucial for the anesthesiologists and intensive care physicians to maintain sufficient oxygenation and ventilation of the patient. Hypoxia is one of the most frequent causes of death or severe neurologic defects in anesthesia. Therefore, it is necessary to have an easy alternative to secure the airways in critical situations.

BACKGROUND AND OBJECTIVES: To determine the visibility of pleural lung sliding in alveolar-interstitial syndrome (AIS) in patients on mechanical ventilation at two different time points, as a confirmatory ultrasonographic method for excluding pneumothorax. METHODS: Fifty-two mechanically ventilated patients in the semirecumbent position in a surgical/neurosurgical intensive care unit with ultrasonographic lung 'comet tails' in three upper anterolateral intercostal spaces, indicating the presence of AIS, were scanned for lung sliding in the same three intercostal spaces with a linear 5-10 MHz transducer after starting mechanical ventilation and on weaning trials. Pneumothorax and atelectasis were excluded by chest radiograph. RESULTS: Absent lung sliding was found in 22.7% of intercostal spaces scanned after starting mechanical ventilation and in 21.2% of scans taken on weaning trials. The lowest invisible rate was in patients with acute heart failure and the highest in patients with acute respiratory distress syndrome. CONCLUSION: Lung sliding specificity in AIS during mechanical ventilation was 78%. Our opinion is that different levels of airway pressure between starting mechanical ventilation and weaning trials have no influence on lung sliding visibility.

Human soluble triggering receptor expressed on myeloid cells (sTREM-1) is a glycoprotein of the immunoglobulin superfamily. In normal lung tissue, sTREM-1 is selectively expressed in lung alveolar macrophages specialized for pathogen clearance and is up-regulated in the presence of bacteria and fungi. The aim of this study was to assess sTREM-1 levels in serum and lungs of patients with ventilator associated pneumonia (VAP) and to evaluate its potential diagnostic role. The study cohort included 31 patients meeting the criteria for VAP, including clinical, microbiological, radiological and laboratory findings in patients on mechanical ventilation for more than 48 hours and with Clinical Pulmonary Infection Score (CPIS) > 6. Serum and lung levels of sTREM-1 were obtained and tested for differences. The samples were analyzed using ELISA technique and the values were expressed in pg/mL. The samples for lung sTREM-1 were obtained from direct bronchial lavage fluid and serum samples from peripheral blood. Differences were tested by Mann Whitney U test with P < 0.05 considered significant. In patients with bacterial VAP, a statistically significant difference was found between serum and lung sTREM-1 levels (P < 0.05), with very high levels of sTREM-1 recorded in lung samples (mean value 1565 pg/mL). There was no statistically significant difference in pulmonary sTREM-1 level between the polymicrobial and monomicrobial VAP groups. In conclusion, sTREM-1 is present in a high concentration in the lungs of patients with bacterial VAP. sTREM-1 levels can help in making the diagnosis of bacterial pneumonia as a standalone marker.

The accuracy of cardiac output measurement by two most widely used methods of less invasive hemodynamic monitoring and by the standard technique of thermodilution with pulmonary catheter was assessed. The measurements were carried out in septic surgical patients immediately after and between system calibrations. Study results showed satisfactory compatibility of measurements performed by the two methods and by pulmonary catheter in both phases, thus system calibration being recommendable in hemodynamically unstable septic patients.

Methicillin-resistant Staphylococcus aureus (MRSA) is an important pathogen throughout the world, and as well in Croatia. Therefore it was decided to develop guidelines with the aim to reduce the number of patients infected/colonized with MRSA in healthcare facilities and in nursing homes in Croatia, consequently reducing MRSA-related morbidity and mortality. An interdisciplinary team of experts developed these guidelines using existing international guidelines from different countries, and literature reviews about prevention, control, treatment and laboratory diagnosis of MRSA infections. Grades of evidence for specific recommendations were determined using CDC/HICPAC grading system. Categorization is based on existing data, theoretical basis, applicability and economic impact. After a broad discussion in different professional societies, Guidelines were accepted. In the meantime, several new possibilities appeared in the treatment of patients with MRSA infections in Croatia, so the Chapter 7.0 Treatment of patients with MRSA infections is changed and updated according to the new treatment possibilities. The rest of the Guidelines was not changed.

The rate of organ donation reflects the level of the respective society and country development. In Croatia, attempts have been made to increase this rate. As a consequence, the number of potential donors with confirmed brain death was observed to have steadily increased during the 2004-2008 period. Data on all potential donors where the confirmation procedure for brain death was completed were retrieved and analyzed. The percentage of donors out of all persons diagnosed with brain death and all deaths recorded at the Central Intensive Care Unit and at all Hospital departments was calculated. The mean number or organs per donor was also calculated. During the 2004-2008 period, the number of donors perbrain death persons was 5/unknown, 6/10, 8/13, 11/13 and 18/20; mean age 51, 50, 39, 48 and 44; donor rate per Central Intensive Care Unit deaths 5.9%, 5.6%, 5.8%, 10.4% and 12.1%; donor rate per all hospital deaths 0.4%, 0.5%, 0.5%, 1.5% and 1.9%; and number of organs per donor 1.6, 2.4, 2.6, 3.0 and 2.7, respectively. Study results showed a steady increase in the number of donors and organs per donor at Sestre milosrdnice University Hospital during the 2004-2008 period. More intensive education should be organized at medical schools and for medical professionals to identify brain death persons and potential donors. In addition, mass media campaigns should improve public awareness and perception of the issue.

Brain death is a clinical diagnosis and must be confirmed by one paraclinical test. This report presents the usefulness of paraclinical tests applied during a 4-year period. Forty-four patients with severe brain lesions leading to brain death were treated during the 2004-2007 period. The appropriate test was chosen according to test availability and patient condition, appreciating restrictions according to the test protocol. Since the results of some tests were inconclusive, some patients underwent repeat testing with the same or different methods. Among 44 patients, 19 had neurotrauma, 11 massive aneurysmal subarachnoid hemorrhage, 1 massive arteriovenous subarachnoid and parenchymal hemorrhage, 12 hypertensive parenchymal hemorrhage, and 1 ischemic stroke. As a primary test, transcranial Doppler (TCD) was used in 30, brain scintigraphy in 2, multislice computed tomography angiography (MSCTA) in 10, and cerebral angiography in 2 patients; the diagnosis was confirmed in 26, 3, 9 and 2 patients, respectively. Due to inconclusive test results, MSCTA had to be repeated in 4 patients twice, and in one patient three times. Four patients where TCD was used died during the observation period, and in one patient the hemodynamic spectrum was inconclusive. In most patients (65%), TCD confirmed the clinical diagnosis of brain death, and in 61% the diagnosis was confirmed within a 2-hour period. TCD was the most useful confirmatory test for cerebral circulatory arrest in brain death diagnosis.
