Background/Aim. Hip replacement surgery can initiate significant postoperative pain caused by bone alterations, implant, and soft tissue or nerve injuries. Postoperative analgesia using regional techniques has been shown to have numerous advantages over the intravenous use of morphine. However, numerous side effects and complications of postoperative continuous epidural analgesia have been reported recently. The aim of this prospective, randomized study was to investigate whether continuous lumbar plexus block can be a safe and efficacious alternative for postoperative analgesia in comparison with epidural analgesia and patient-controlled analgesia with morphine (PCA morphine) for hip arthroplasty. Methods. This prospective study included 60 patients, scheduled for total hip arthroplasty. Patients were randomized into 4 groups: the group central nerve block - epidural (CNB), the group peripheral nerve block - lumbar plexus block (PNB), the group spinal anesthesia-PCA morphine (SAM) and the group general anesthesia-PCA morphine (GAM). The quality of analgesia and side effects (hypotension, nausea, vomiting, urinary retention) were recorded in all groups at 4 h, 12 h, and 24 h after surgery. Pain scores were assessed using Visual Analogue Scale (VAS), both at rest and on moving. Results. Our findings demonstrated that the use of a continuous lumbar plexus block provides effective analgesia at rest and on moving, during 24 h after hip arthroplasty. Pain scores varied significantly among the groups 4 h postoperatively (F = 21.827; p < 0.01), 12 h postoperatively (F = 41.925; p < 0.01) and 24 h postoperatively (F = 33.768; p < 0.01) with the highest scores ≥ 3 in the GAM group. Patients from the PNB group had satisfactory analgesia, comparable with patients from the CNB group. The incidence of nausea was significantly lower in the PNB group 12 h after the operation (χ2 = 9.712; p < 0.01). The incidence of urine retention was significantly different 12 h after the operation, with a presence only in the CNB group, with the incidence of 33.3% (χ2 = 16.365; p < 0.01). In all studied groups, the incidence of hypotension was not significantly different postoperatively. Conclusion. Administration of postoperative analgesia using continuous lumbar plexus block produces satisfactory analgesia with a low incidence of side effects when compared to epidural analgesia or parenteral opioids following hip arthroplasty. © 2017, Institut za Vojnomedicinske Naucne Informacije/Documentaciju.

Background/Aim. Early assessment of severity and continuous monitoring of patients are the key factors for adequate treatment of acute pancreatitis (AP). The aim of this study was to determine the value of procalcitonin (PCT) and Bedside Index for Severity in Acute Pancreatitis (BISAP) scoring system as prognostic markers in early stages of AP with comparison to other established indicators such as Creactive protein (CRP) and Acute Physiology and Chronic Health Evaluation (APACHE) II score. Methods. This prospective study included 51 patients (29 with severe AP). In the first 24 h of admission in all patients the APACHE II score and BISAP score, CRP and PCT serum concentrations were determined. The values of PCT serum concentrations and BISAP score were compared with values of CRP serum concentrations and APACHE II score, in relation to the severity and outcome of the disease. Results. Values of PCT, CRP, BISAP score and APACHE II score, measured at 24 h of admission, were significantly elevated in patients with severe form of the disease. In predicting severity of AP at 24 h of admission, sensitivity and specificity of the BISAP score were 74% and 59%, respectively, APACHE II score 89% and 69%, respectively, CRP 75% and 86%, respectively, and PCT 86% and 63%, respectively. It was found that PCT is highly significant predictor of the disease outcome (p < 0,001). Conclusion. In early assessment of AP severity, PCT has better predictive value than CRP, and similar to the APACHE II score. APACHE II score is a stronger predictor of the disease severity than BISAP score. PCT is a good predictor of AP outcome.
