Randomized Controlled Trial Comparative Study
The effect of ulinastatin on postoperative blood loss in patients undergoing open heart surgery with cardiopulmonary bypass.
This prospective, randomized, double-blind study evaluated the effect of ulinastatin on postoperative blood loss and transfusion requirements of patients undergoing open-heart surgery with cardiopulmonary bypass (CPB) and aortic cross-clamping (ACC). CPB and ACC produce variable systemic inflammatory reactions that are associated with multiorgan dysfunction via leucocytes, especially polymorphonuclear neutrophils (PMNs). PMNs increase blood loss and transfusion requirements. ⋯ There were no statistically significant between-group differences in postoperative blood loss and transfusion requirements. Ulinastatin caused a non-significant decrease in duration of intubation. Patients who received ulinastatin had significantly shorter ICU stays than control patients.

Randomized Controlled Trial Clinical Trial
Effect of single-injection versus continuous local infiltration analgesia after total knee arthroplasty: a randomized, double-blind, placebo-controlled study.
In this randomized, double-blind, placebo-controlled, single-centre study, 80 patients (American Society of Anesthesiologists physical status I-III) received postoperative single-injection local infiltration analgesia (SLIA), continuous local infiltration analgesia (CLIA) or placebo (control group). Intravenous patient-controlled morphine was used as rescue analgesia. ⋯ Patient satisfaction was higher, and maximum flexion of the knee on postoperative days 7 and 90 was greater, in the CLIA group compared with the SLIA group. CLIA provided prolonged superior analgesia and was associated with more favourable functional recovery and patient satisfaction compared with SLIA.

Randomized Controlled Trial
The analgesic effect of dexketoprofen when added to lidocaine for intravenous regional anaesthesia: a prospective, randomized, placebo-controlled study.
This prospective, randomized, placebo-controlled study evaluated the effects of dexketoprofen as an adjunct to lidocaine in intravenous regional anaesthesia (IVRA) or as a supplemental intravenous (i.v.) analgesic. Patients scheduled for elective hand or forearm soft-tissue surgery were randomly divided into three groups. All 45 patients received 0.5% lidocaine as IVRA. ⋯ The times of sensory and motor block onset, recovery time and postoperative analgesic consumption were recorded. Compared with controls, the addition of dexketoprofen to the IVRA solution resulted in more rapid onset of sensory and motor block, longer recovery time, decreased intra- and postoperative pain scores and decreased paracetamol use. It is concluded that coadministration of dexketoprofen with lidocaine in IVRA improves anaesthetic block and decreases postoperative analgesic requirements.

Randomized Controlled Trial
The effect of ketamine with remifentanil for improving the quality of anaesthesia and recovery in paediatric patients undergoing middle-ear ventilation tube insertion.
This prospective randomized study evaluated the effects of ketamine with remifentanil to improve the quality of anaesthesia and postoperative recovery, following brief procedures, in 60 paediatric patients undergoing middle-ear ventilation tube insertion (MEVTI). Patients were randomly assigned to either ketamine 2 mg/kg intravenous [i.v.] bolus plus normal saline by i.v. infusion (K group, n = 30) or ketamine 2 mg/kg i.v. bolus, plus remifentanil 0.15 μg/kg per min i.v. infusion (KR group, n = 30). ⋯ Time to recovery was significantly shorter in the KR group than in the K group. In conclusion, remifentanil was a good adjuvant to ketamine, improving the quality of anaesthesia and postoperative recovery in children undergoing MEVTI.

Case Reports
Dural metastasis of atypical extraventricular neurocytoma with the codeletion of chromosomes 1p/19q.
Extraventricular neurocytoma (EVN) is a rare neoplasm described in the 2007 World Health Organization classification of tumours of the nervous system. Due to the rarity of the tumour, there is limited literature available. The clinical characteristics, pathological features, biological behaviour and outcome of EVN remain unclear, and there are challenges regarding its diagnosis and management. ⋯ Atypical pathological features included vascular proliferation, the presence of mitosis and a high MIB-1 (an antibody against Ki-67) labelling index. The disease recurred 7 months after the initial complete resection and radiation treatment, presenting with dural metastasis and codeletion of chromosomes 1p/19q. The present case history and treatment course are discussed with respect to the literature.
