Abstract

The aim of the present work was to assess systemic hemodynamic changes using PiCCo monitoring in a porcine model of E. coli-induced fulminant sepsis. Thirty-one healthy female Hungahib pigs were randomly assigned into control (n= 15) or septic groups (n= 16). In the sepsis group Escherichia coliculture was intravenously administrated in a continuously increasing manner according to the following protocol: 2 ml of bacterial culture suspended in physiological saline was injected in the first 30 min, then 4 ml of bacterial culture was administered within 30 min, followed by infusion of 32 ml bacterial culture for 2 h. Control animals received identical amount of saline infusion. Systemic hemodynamic parameters were assessed by PiCCo monitoring in both groups. Resting hemodynamic parameters were identical in the two groups. In control animals, systemic hemodynamic variables were relatively stable during the entire procedure. In septic animalsshock developed in 165 (IQR: 60–255) min after starting the injection of E. colisolution. Blood pressure values gradually decreased, whereas pulse rate increased. A decrease in cardiac index, an increased systemic vascular resistance, and a decreased stroke volume variation were observed. These results may serve as additional pathophysiological information of hemodynamic changes occurring during hypodynamic sepsis and may contribute to a better understanding of the pathomechanism of septic multiple organ failure.

Abstract

Introduction: In 1968 R. E. Fear first reported a trocar site hernia (TSH) in his large series on laparoscopy. Currently, the incidence of TSH is estimated to be 0.65-2.80%. Ports ≥10-mm are usually closed, but ports of the 5-mm trocars are always left open, which may lead to herniation., Material and Methods: Authors guided teaching courses for hands-on animal laparoscopic cholecystectomy (LC) operations, where trainees performed LC-s on 60 animals. Two and four weeks following the operations the animals underwent second look laparoscopy to detect adhesion formation., Results: Trocar site herniation was observed, and in 20% of the animals herniation was found. 70% of the hernias were situated in the 5-mm ports and 30% in the 10-mm ports., Conclusion: Port sites should be closed to prevent the formation of TSH. Attention should be payed on the closure of 5-mm trocar sites as well.

Abstract

The authors provide a review about the main parameters of the gradual and postgradual educational activity of the Department of Operative Techniques and Surgical Research between 2000-2013. In this period of time several new subjects and courses have been introduced. The thematics have been widened, and the educational topics underwent a significant change and development: new teaching videos, revised note-books and a new textbook have been prepared through these years. Further, new training models (surgical training models, phantom and biomodels) have also been evolved. The educational activity of the Department was supported significantly several times (financial, contribution, grants) from the University of Debrecen, partner companies, HEFOP and TÁMOP grants. Infrastructural development in conjunction with the above increased the quality of educational standards in gradual and postgradual education, too. All these changes and developments were presented on various professional meetings and published in relevant journals, as part ofinternal quality control.

Abstract

Intermittent compression of the structures of the hepatoduodenal ligament, is often performed during liver surgery. As a result, changes in hepatic blood supply and consequent reperfusion induced tissue damages will develop. Ischemia-reperfusion injury, which occur in local and distant regions, influence outcome of hepatic surgery, and it is in close correlation with the duration of hypoxia during the intervention. In animal model the effect of Baron/Pringle manoeuvre was investigated in terms of changes in liver function tests and histology. The study was carried out on 12 Beagle dogs, clamping of the hepatoduodenal ligament for 3×15 minutes then half an hour reperfusion was performed followed by blood and tissue sampling. Significant histological changes were observed both in the liver as well as the small intestine. In terms of liver function changes, GPT elevation occurred the earliest, GOT and LDH were also increased at the end of the 30 minutes reperfusion. In this animal model, the third 15 minutes compression turned out to be too long. Elevation in GPT levels was the most sensitive marker.
