OBJECTIVE To compare the use of crossed K-wire and prebent intramedullary nail techniques for the fixation of distal radius metaphyseal fracture in children. METHODS Intraoperative and follow-up data for children with distal radius metaphyseal fracture, treated using crossed K-wire or prebent intramedullary nail fixation, were retrospectively analysed. Patient groups were matched for age, sex...

Background: Various drugs are used as adjuvants to improve the quality of supraclavicular block. Objective: This study aimed to investigate the effect of adding dexmedetomidine to lidocaine on the characteristics of supraclavicular block in upper limb surgeries. Methods: This double-blind controlled clinical trial was conducted on patients undergoing upper extremity fracture surgery under a ...

BACKGROUND AND OBJECTIVES The processed analysis of electroencephalogram became extremely important to monitor nervous system, being used to obtain a better anesthetic adequacy. The objective was to conduct a review about each processed parameter, defining its real importance. CONTENT A review was conducted showing mathematical, physical and clinical aspects as well as their correlations and ...

We demonstrate for the first time the application of an endoscopic fluorescence lifetime imaging microscopy (FLIM) system to the intraoperative diagnosis of glioblastoma multiforme (GBM). The clinically compatible FLIM prototype integrates a gated (down to 0.2 ns) intensifier imaging system with a fiber-bundle (fiber image guide of 0.5 mm diameter, 10,000 fibers with a gradient index lens objec...

Evoked potentials have been successfully monitored intraoperatively to provide valuable real-time information to surgeons and reduce unfavorable surgical outcome. However, the inability to reliably record Visual evoked potentials (VEPs) in the operating room continues to limit its use. Several factors technical, anesthetic and others, have been looked into by various groups, but with limited su...

Breast cancer detection and staging are constantly evolving as technologies improve. Breast cancer surgery is also undergoing continuous refinement, with the objective being to achieve optimal cosmetic results. Surgery has been combined with intraoperative radiation therapy to achieve the best local-disease control with minimal side-effects. The adjuvant strategy of treatment is a 'hot' issue i...

Intraoperative imaging is used more frequently today since this enables the surgeon to localize structures inside the brain more accurately and helps to detect shape changes. In order to combine informations derived at different time points, we describe a nonrigid registration algorithm that aligns MR scans of the brain. Based on a set of feature points, an initial sparse estimate of the displa...
