This study was conducted to evaluate the relation between extraarticular distal radius fractures associated with fracture of ulnar styloid and the rota-tional movements of the wrist and forearm. Patients and methods: 47 patients with an extraarticular distal radius fracture were enrolled in a prospective case control study. The patients were visited in regular follow up intervals after treatment and at the final follow up the rotational movements of the forearm were measured. The findings were analyzed with Independent T and Chi-square tests. Findings: Ultimately 23 patients of the group 1 (intact ulnar styloid) and 24 of the group 2 (fractured ulnar styloid) completed the follow up period. At this time supination of the wrist and forearm in group 2 was significantly less than the group 1 (p< 0.001). Conclusion: It seems that the association of an extraarticular distal radius fracture with the fracture of ulnar styloid, at least in short term causes restriction of supination of the forearm, though the mechanism and clinical significance of this finding cannot be easily explained.展开更多

Endoscopic Sinus Surgery (ESS) is one of the surgeries which need a clear field and the amount of bleeding profoundly impacts the ability of surgeons. Current study was designed to evaluate the effect of remifentanil combined with propofol versus Isoflurane on blood loss during ESS and its possible interaction with Depth of Anesthesia. Fifty one patients comprising 15 females and 36 males undergoing ESS were chosen for this study. One group received propofol and remifentanil to induce and maintain anesthesia and the second group received Isoflurane. Mean Arterial Blood Pressure (MAP), Depth of Anesthesia and total blood loss were recorded for the patients of both group. Data were analyzed using t-test, Repeated Measures ANOVA and Pearson’s correlation. P 0.05 was considered statistically significant. Both agents induced hypotension during surgery. No significant difference was observed in total blood loss between two groups. DA was decreased in both groups, but no significant correlation was found between DA and MAP or DA and blood loss. There is no significant difference between remifentanil combined with propofol and Isoflurane in decreasing blood loss during ESS, thus we suggest usage of hypotensive anesthetic agent regardless of its type is ESS.展开更多
