This article compares the performance of WDM lightpath protection and IP LSP protection schemes for IP-over-WDM networks. A mathematical formulation of the maximum throughput problem is presented and analytical expressions for recovery time are derived for both schemes. The throughputs and recovery times are analyzed and compared. Results show that the IP LSP protection scheme presents higher t...

background: emergence delirium (ed) is a frequent postoperative complication in children. its prevalence is about 25-80% and is observed more commonly with rapid-acting volatile anesthetics than the older inhalation agents. methods: 30 patients aging between 2 to 8 years were included in this randomized double blind study. we compared the effect of combination of two anesthetic drugs, propofol-...

conclusions intravenous administration of paracetamol immediately after knee arthroscopy improved postoperative pain, decreased analgesic administration, maintained stable hemodynamic parameters, had no complications related to opiates, no nausea and vomiting, and increased patient satisfaction and comfort in comparison to pca with morphine. results there was no significant difference regarding...

BACKGROUND The purpose of this study was to examine whether the time required for recovery from transient hypoparathyroidism is correlated with the onset of hypocalcemic symptoms in patients with total thyroidectomy. METHODS Medical records of 54 patients were retrospectively reviewed. The correlation between the onset of hypocalcemic symptoms and the recovery time were compared for all patie...

OBJECTIVE To assess the care provided to patients with congenital heart diseases and ischemic heart diseases undergoing cardiac surgery according to the fast-track recovery protocol compared with those undergoing the conventional procedure. METHODS The transfer of patients from one hospital unit to another was assessed for 175 patients, 107 (61%) men and 68 (39%) women, with ages ranging from...

We used a modified photostress recovery test (PSRT) with microperimetry in a scanning laser ophthalmoscope (SLO) to evaluate the extrafoveal region. After the red-target threshold was determined, the retina was bleached with argon green laser illumination. Test spots were presented every 3 seconds at the testing point and subjects indicated when they saw the spot. We determined the recovery tim...
