Randomized Controlled Trial Comparative Study Clinical Trial
The effect of acute normovolemic hemodilution and acute hypervolemic hemodilution on coagulation and allogeneic transfusion.
In this study, acute normovolemic hemodilution (ANH) and hypervolemic hemodilution (HHD) were compared with no hemodilution with regards to the effectiveness in blood usage and coagulation parameters. ⋯ We conclude that hemodilution (both ANH and HHD) decreases the demand for homologous blood without adversely affecting hemodynamics or coagulation parameters and HHD seems to be a simple and valuable alternative to ANH in orthopedic patient undergoing hip replacement.

Focused Assessment Sonography for Trauma (FAST) is not widely practiced by Trauma Surgeons in the Middle East despite its international acceptance. A FAST course was established by the Trauma Group at the Faculty of Medicine and Health Sciences at United Arab Emirates (UAE) University aiming to introduce doctors who have limited experience of ultrasound to the basics of FAST. This article summarizes the content of the course; the evaluation of the participants and their recommendations. ⋯ Organizing a FAST course is an important step towards recognizing and implementing it in practice. Nevertheless, there is a need for appropriate quality assurance and credentialing guidelines before commencing.

Cricothyroid space (CS) is one of the thinnest part in the framework of the larynx. The close relations of CS to the intralaryngeal subglottic area increase its anatomical importance. The aim of this study was to establish topographic distribution and the number of perforating vessels lying towards the intralaryngeal subglottic region and finding the calibrations of these vessels, thus revealing an index for the Turkish population. ⋯ The cricothyroid area is an anatomical compartment enclosed by a connective tissue membrane and connected to the adjacent laryngeal region by vessels. This region is important with regard to surgical procedures, spread of laryngeal cancer and traumatic lesions of the larynx. Therefore, the clinical and surgical importance of vascular anatomy and the dimension of the cricothyroid space should be given emphasis in our population.
