In this study, we aimed to determine psychological factors that might contribute to this response. We hence investigated patients undergoing a standardized surgical intervention (open nephrectomy). Patients and methods: Between May 2014 and April 2015, we conducted a prospective observational cohort study. The following psychological tests were administered preoperatively: Mini-Mental State Examination, Amsterdam Preoperative Anxiety and Information Scale (APAIS), Hamilton Anxiety Rating Scale, Hamilton Depression Rating Scale, and Pain Catastrophizing Scale. The primary outcome, postoperative pain intensity (11-point numerical rating scale, [NRS]), was assessed in the “immediate early” (first 8 hours), “early” (12 and 24 hours), and “late early” periods (48 and 72 hours).Results: A total of 196 patients were assessed, and 150 were finally included in the study. NRS scores improved from 4.9 (95% confidence interval [CI]: 4.7–5.1) in the “immediate early” to 3.1 (95% CI: 2.9–3.3) in the “early” and 2.3 (95% CI: 2.1–2.5) in the “late early” postoperative period. Most (87%) patients received intravenous opioids, while 13% received analgesics epidurally. Repeated measures analysis of variance indicated better pain management with epidural analgesia in the first two postoperative periods (F=15.01, p

Objectives This study investigates the effects of high glucose content on patients undergoing cold crystalloid versus cold blood cardioplegia in terms of early clinical results, functional myocardial recovery and ischaemia-reperfusion injury in patients undergoing repair of acyanotic cardiac lesions. Methods Patients were randomly assigned to receive either crystalloid (n = 31) or blood cardioplegia (n = 31). Early clinical results were assessed. Changes in left ventricular fractional shortening, arterial blood lactate levels, central venous saturation, cardiac Troponin I release and blood glucose concentration were measured during the first 24 h after ischaemia. Results There was no significant difference in clinical outcomes and postoperative complication rates between groups. The postoperative changes in left ventricular function, lactate levels, central venous saturation and Troponin I were not significantly different between groups. The use of crystalloid cardioplegia was associated with significant increases in serum glucose compared with blood cardioplegia. Conclusions A high glucose content blood cardioplegia does not show any advantage compared with crystalloid cardioplegia in terms of clinical outcomes, functional recovery and the degree of ischaemic injury in infants and children undergoing repair of acyanotic heart lesions. High glucose concentration of the cardioplegic solution might potentiate ischaemia-reperfusion injury and diminish the beneficial effects of blood cardioplegia.

Minimal Sedation (Anxiolysis) is a drug-induced state during which patients respond normally to verbal commands. Although cognitive function and physical coordination may be impaired, airway reflexes, and ventilatory and cardiovascular functions are unaffected. Moderate Sedation/Analgesia ('Conscious Sedation') is a drug-induced depression of consciousness during which patients respond purposefully to verbal commands, either alone or accompanied by light tactile stimulation. No interventions are required to maintain a patent airway, and spontaneous ventilation is adequate. Cardiovascular function is usually maintained. Dexmedetomidine is a new generation highly selective α2-adrenergic receptor (α2-AR) agonist that is associated with sedative and analgesic sparing effects, reduced delirium and agitation, perioperative sympatholysis, cardiovascular stabilizing effects, and preservation of respiratory function.

To compare the total fluoroscopy time (FT) based on the fluoroscopy mode used-continuous vs. pulsed-in patients who underwent percutaneous nephrolithotomy (PCNL). The study cohort evaluated 111 patients who underwent PCNL by a single surgeon. Standard (continuous) fluoroscopy of 30 frames per second (fps) was used in the first 56 cases (SF group), while the next 55 consecutive cases were performed under pulsed fluoroscopy of two fps (PF group). The presence of surgeon's previous experience decreased the possible impact of the learning curve on the outcome. In both groups, using ultrasound in combination to fluoroscopy performed the renal access. The stone complexity was determined using Guy's stone score (GSS). Complications were evaluated using Clavien-Dindo classification. Median FT was significantly lower in PF group (76.8 s) compared to SF group (155.4 s) (p

Inflammation plays a key role in the development of benign prostatic hyperplasia. Prostaglandin E2 (PGE2) is an important inflammation factor found in enlarged prostatic tissue that can be the main cause of inflammatory pain. The aim of this study was to investigate whether epidural anesthesia can block the negative effects of prostaglandin mediators during prostate surgery.The study included 60 patients who underwent open prostatectomy. All patients were randomly allocated to one of two study groups. The first group received general anesthesia and the second group a combination of general and epidural anesthesia. Main outcome measures were plasma concentration of PGE2, adrenaline, noradrenaline, and dopamine, before induction of anesthesia and at the time of enucleation.Preoperative serum concentrations of PGE2 were high in both groups. During enucleation, serum concentrations of adrenaline, noradrenaline, and dopamine increased, followed by a rise of systolic and diastolic blood pressure in the group of patients that received only general anesthesia. Serum concentration of PGE2 was at the same level as before induction of anesthesia in both groups.Epidural anesthesia blocks transmission of painful stimulus through the spinal cord caused by prostaglandin release and prevents the rise of catecholamines and blood pressure. Open prostatectomy can become a safer procedure performed under a combination of general and epidural anesthesia. Negative intraoperative effects of inflammatory prostate mediators during other techniques for prostate surgery could also be blocked with epidural anesthesia.

To examine the relationship between biochemical markers and morphologic sperm characteristics, including head, neck, and tail changes.The study evaluated 154 patients who went to the Andrology Laboratory of the Clinic of Urology, Clinical Center of Serbia. Patients were divided into 4 groups: normozoospermic, oligozoospermic, severe oligozoospermic, and asthenozoospermic, according to the sperm concentration and motility.The differences in creatine kinase (CK) and CK-M levels between normozoospermic and the 2 groups of oligozoospermic patients were significantly different (P.01). The CK and CK-M levels correlated negatively with sperm concentration and sperm motility, but correlated positively with the pathologic sperm form. Patients with CK values0.093 have a total number of pathologic forms higher than 0.40 (87.5% sensitivity, 77.3% specificity, the area under the curve was 0.832, P.001). Patients with CK values0.09 U/L have normal spermatogenesis and pathologic disorder of the head15%, neck12%, and tail10%.The relation between sperm morphology and biochemical markers included in the maturation process is established during the sperm genesis process. If the results of these markers are used together with the morphology of the spermatozoa in the interpretation of infertility, it would lead us to better insight of the fertility potential of the each patient.

Purpose Optimal analgesia in ambulatory urology patients still remains a challenge. The aim of this study was to examine if the pre-emptive use of intravenous tramadol can reduce pain after ureteroscopic lithotripsy in patients diagnosed with unilateral ureteral stones. Materials and Methods This prospective pilot cohort study included 74 patients diagnosed with unilateral ureteral stones who underwent ureteroscopic lithotripsy under general anesthesia in the Urology Clinic at the Clinical Center of Serbia from March to June 2012. All patients were randomly allocated to two groups: one group (38 patients) received intravenous infusion of tramadol 100 mg in 500 mL 0.9%NaCl one hour before the procedure, while the other group (36 patients) received 500 mL 0.9%NaCl at the same time. Visual analogue scale (VAS) scores were recorded once prior to surgery and two times after the surgery (1 h and 6 h, respectively). The patients were prescribed additional postoperative analgesia (diclofenac 75 mg i.m.) when required. Pre-emptive effects of tramadol were assessed measuring pain scores, VAS1 and VAS2, intraoperative fentanyl consumption, and postoperative analgesic requirement. Results The average VAS1 score in the tramadol group was significantly lower than that in the non-tramadol group. The difference in average VAS2 score values between the two groups was not statistically significant; however, there were more patients who experienced severe pain in the non-tramadol group (p
