Jurnalul de Chirurgie , 2011,
Abstract: Objective: The study aimed to identify the variation of biological parameters recorded at the patients with obstructive renal failure treated with percutaneous nephrostomy. Material and method: The retrospective study investigated the data of 244 patients admitted in our department and treated with percutaneous nephrostomy for obstructive renal failure during January 2005 – December 2007. Demographical data, investigation, operation notes, indication, biological parameters trends (creatinine, haematocrit, haemoglobin, kaliemia, alkaline reserve), complications and hospital stay were recorded. The biological parameter trends (creatinine, haematocrit, haemoglobin, kaliemia, alkaline reserve) was analysed. The median preoperative and postoperative values of those parameters was compared. Statistical analysis was performed.Results: The median preoperative/discharge values of creatinine were 8.29mg%(1.6-26.3 mg%) comparing to 3.63mg% (0.64-13 mg%). A return to normal renal function at the discharge time was noted in 23 patients (9.7%). Hyperpotasemia (K>5.1mEq/l) on admission was found in 134 patients (54.9%). The median preoperative/discharge values of potassium were 5.71mEq/l comparing to 4.8 mEq/l.The median hospitalization time was 8.7 days with a median ICU stay of 3.3 days. The recorded mortality was 3.2% (8 patients) with an average time of 5.8 days between the operatory time and exitus time. Conclusions: The most frequent causes of obstructive renal failure necessiting percutaneous nephrostomy are malignancies. After renal percutaneous drainage the renal function improvement is fast and significant. In the postoperative period the onset of severe hypokalemia call for aggressive treatment in the same time with volume repletion.
Biomarkers in early diagnosis of sepsis.
Irina Ristescu,Ioana Grigora?
Jurnalul de Chirurgie , 2012,
Abstract: Purpose of review. Sepsis is a complex pathology with a high morbidity and mortality rate. Many studies demonstrate that early diagnosis is crucial to survival. Sepsis is a difficult to diagnose disorder due to lack of specificity and sensibility of signs and symptoms and limitations of current microbial detection techniques. We review in this article the advantages and disadvantages of mainly used biomarkers for the diagnosis of systemic infections. Recent findings. In the last decades a large number of serum biomarkers have been proposed for clinical application with the main purpose of distinguishing between systemic inflammation and systemic infection. Their clinical usefulness and limitations are under reviewed. Summary. Along with clinical evaluation, sepsis biomarkers may improve the diagnostic evaluation of patients with systemic infections. Taking into account the actual diagnostic usefulness of each single biomarker, future research is needed to explore the benefit ofmultiple biomarkers panel.
LEPTIN, A NEW PROINFLAMMATORY MARKER AND BODY COMPOSITION – CORRELATIONS DURING EARLY POSTOPERATIVE PERIOD AFTER MAJOR SURGERY

Jurnalul de Chirurgie , 2011,
Abstract: Introduction: Leptin is an adipokine regulating energy balance but recently has been related to immune system and inflammatory response. Objectives: To investigate the correlation between leptin plasma level and body composition in patients with signs of systemic inflammatory response syndrome after major abdominal surgery and to characterise early dynamics of this and other proinflamatory cytokines in such patients. Methods: We prospectivelly enrolled 40 patients divided in 2 groups: study group (20 pts) – patients with major abdominal surgery and signs of SIRS and control group (20 pts) – preoperative patients without inflammatory disease. Plasma concentration of leptin, CPR and IL6 were measured preoperatively in both groups and in first three days postoperative (9 samples) in the study group. Body composition (percent of body fat, lean body mass, total body water) was recorded using bioelectrical impedance analysis method. Results: In control group leptin has a positive correlation (r2=0.52) with the percent of body fat. In study group this correlation is present (r=0.85) preoperatively but is lost at 24,48 and 72 hours postoperative measurements (r=0.04, 0.07, 0.15). In study group leptin acts as a pro-inflammatory cytokine. The plasmatic peak of 17.31 ng/ml is reached at 12 h, later than IL 6 (plasmatic peak at 6h) but earlier comparing with CRP (plasmatic peak at 24h). Conclusions: In patients with major abdominal surgery and SIRS leptin acts as a proinflammatory mediator with mainly extraadipocitary source. Leptin has specific early dynamics and may be useful as an early diagnostic marker of systemic inflammation.
THE IMPACT OF INTRAABDOMINAL HIPERTENSION IN OUTCOME OF SEVERE ACUTE PANCREATITIS

Jurnalul de Chirurgie , 2011,
Abstract: Background: Severe acute pancreatitis (SAP) is a condition significantly associated with morbidity and mortality, despite of therapeutic progresses. Several published papers show a high incidence of intraabdominal hypertension (IAH) and abdominal compartment syndrome (ACS) in SAP. IAH is both the result of progressive intraabdominal and retroperitoneal edema, and of intravascular volume therapy. SAP with IAH results in longer Intensive Care Unit (ICU) stay and higher mortality. Despite the proliferation of scoring systems for grading SAP, unfortunately, none has yet proven to be a consistently accurate predictor of the clinical course. Methods: The retrospective study enrolled patients (pts) with SAP and APACHEII>12, during a 3 years (2006-2008) period. The incidence of IAH (IAP ≥12mmHg) and ACS was recorded. IAP was monitored by measuring urinary bladder pressure .The occurrence of organ dysfunction during ICU stay was registered. Severity and prognosis were assessed by APACHE II and SOFA scores. The relationship between IAP, organic dysfunctions and mortality in PAS was analysed. Results: Out of 55 pts (the study group) 37pts (70%) had IAH at admission(18,9+/-4,48) and 9 pts (12,545%) had ACS at admission. During ICU stay 45pts (81,81%) had IAH and 29pts (52%) had ACS. Despite the high incidence of organic dysfunction in our patients, there was no correlation between IAH and organic dysfunction in the study group. APACHE II and SOFA scores were significantly higher at ICU admission, but also during ICU stay in pts with admission IAH compared to patients without admission IAH.These data lead to the idea that admission IAH is a marker of poor prognosis in SAP patients. Patients with admission IAH had a longer ICU stay (10,8+/-8,6 zile) as compared with patients without admission IAH, but the difference was not stastistically significant (p=0,400). In the study group 29pts (52,7%) died. During ICU stay 25/29 nonsurvivors (86,2%) had IAH at admision and 27/29 (93,1%) had worst IAP higher than 12mmHg. During ICU stay survivors had a worst IAP of 19,53+/-2,08, while nonsurvivors had 24,125+/-1,66 (p=0,26).Conclusions: Routine IAP monitoring at ICU admission and during ICU stay is mandatory in SAP patients because IAP strongly corelates with admission APACHE II and SOFA scores. Nonsurvivors have higher admission IAP compared with survivors and 86%of nonsurvivors had IAH at admision. We may conclude that admission IAH may signal a high degree of severity and a poor prognosis in SAP patients.

Abstract: Розглянуто вплив випаровуваност альтернативних палив на р шення проблеми холодного пуску двигуна за рахунок використання пропан-бутаново сум ш для п двищення тиску насичено пари. Volatility fuels fraction of the estimated parameters and letkosti. Volatility characterizes the ability to switch fuels in vaporous state. Selecting indicators to assess the volatility depends on the chemical composition of fuel. The main measure letkosti etanolnogo fuel is vapor pressure. The most simple and cost-effective to improve cold start is putting in fuel lehkoletyuchyh components: butane, izopentanu, gas and other petroleum. It was investigated the influence of DEE on alcohol-gasoline blend, the results show that DEE positive impact on increasing vapor pressure to the desired minimum for starting the engine. But because the ether to 19%, then at such high levels can actively formed peroxide compounds, which is undesirable. Very promising is the use of propane-butane gas mixture as lehkoletyuchoyi gaseous component. Butanizovani spirit-petrol mixture can be recommended for use as alternative fuel vehicles after further study of their stability and himmotolohichnyh characteristics. Автомобильные бензины и альтернативные биологические топлива на основе этанола преимущественно предназначены для применения в двигателях внутреннего сгорания. При использовании альтернативного биологического топлива, особенно этанольного, возникает проблема недостаточной испаряемости бензина при низкой температуре, в результате чего в холодное время года двигатель может не запуститься. Пусковые свойства бензина зависят от содержания в них летучих фракций или летучих соединений. Проблему холодного запуска предлагается решать за счет использования пропан-бутановой смеси для повышения давления насыщенного пара. Для перспективного применения газов пропан-бутановой смеси легколетучего газообразного компонента необходимы дальнейшие исследования стабилизации такой композиции.
