Laboratory tests were carried out on cadaver animal bones to evaluate the thermal effect of inserting K-wires with a pneumatic hammer as compared to drilling. The mean maximum bone temperature 0.5 mm from the K-wires was 34 (22-72) degrees C using the hammer and 54 (19-100) degrees C for drilling, 1.0 mm from the K-wire the mean maximum temperature was 31(More)
Perioperative intravenous (IV) infusion of lidocaine has been shown to decrease post-operative pain, shorten time to return of bowel function, and reduce the length of hospital stay. This randomized, prospective, double-blinded, placebo-controlled clinical trial evaluated the impact of IV lidocaine on the quality of post-operative analgesia and other(More)
BACKGROUND Transfusion of allogeneic blood influences outcome after surgery. Despite widespread availability of transfusion guidelines, transfusion practices might vary among physicians, departments, hospitals and countries. Our aim was to determine the amount of packed red blood cells (pRBC) and blood products transfused intraoperatively, and to describe(More)
The aims of this study were to assess the prevalence of paraneoplastic rheumatic syndromes in a cohort of patients with newly diagnosed solid tumours and to describe their autoimmune profile, comparing it to the controls. Screening questionnaires (3,770) were distributed, and during a three-step study, 94 patients were confirmed to have both paraneoplastic(More)
Induced hypotension with epidural anesthesia influences the intraoperative blood loss in prostate cancer patients undergoing radical prostatectomy. The aim of this study was to evaluate intraoperative blood loss and need of blood transfusions in patients who underwent radical prostatectomy under epidural/general anesthesia and general anesthesia. Two groups(More)
Hand-assisted laparoscopic colectomy is an alternative technique to laparoscopy: it is technically easier, learning curve and operative time is shorter. We aimed to describe the characteristics of patients admitted due to colorectal cancer for hand-assisted laparoscopic surgery (HALS), intra- and postoperative clinical and functional outcomes. A(More)
OBJECTIVE This study evaluated effectiveness of hypotensive epidural anesthesia in decreasing blood loss, operation and extubation time, opiates use and stay in intensive care unit. MATERIAL AND METHODS Fifty-eight patients were enrolled in the study. Right (n=16) or left (n=42) pneumectomy was performed for the study patients. We used the hypotensive(More)
PURPOSE This study was performed in order to evaluate effectiveness of controlled hypotension decreasing blood lose in transthoracic esophageal resection. PATIENTS AND METHODS Thirty-six patients were enrolled in this randomized study. The patients were divided in to two groups. We used controlled hypotension induced by thoracic epidural anaesthesia for(More)
Introduction For more than the last 20 years, low anterior resection with total mesorectal excision (TME) is a gold standard for rectal cancer treatment. Oncological outcomes have improved significantly and now more and more reports of functional outcomes appear. Due to the close relationship between the rectum and pelvic nerves, bowel, bladder, and sexual(More)
Modifications of heart rate variability were investigated during intravenous-inhalation anesthesia in 80 cancer patients. Heart rate was recorded during active orthostatic test before surgical intervention as well as during: (1) before operation; (2) after atropine (0.01 mg/kg); (3) after intubation; (4) at the beginning of operation; (5) after 30 min from(More)
