In an infusion test the apparent rate of cerebrospinal fluid (CSF) production is temporarily increased through injection of fluid directly into the CSF system with the result that CSF pressure rises, in theory to a new plateau average, and the change in pressure level gives a measure of resistance to CSF outflow and the rate of approach to the plateau gives information about cerebral compliance...
A finite element code, in modular form, has been developed to model the complete three-dimensional resin film infusion (RFI) process. The problem formulation and its analysis incorporate compaction of the anisotropic elastic porous preform, elastic deformations of the tooling components, heat transfer in the resin, flow of resin through the preform, cure kinetics of the resin, and the heat tran...
OBJECTIVE: Hyperglycemia is associated with increased morbidity and mortality in diabetic patients following coronary artery bypass grafting. Tight glycemic control in perioperative period can reduce these events. The goal of this study was to determine whether combination of continuous infusion and subcutaneous glargine as a basal insulin could improve glycemic control. MATERIAL AND METHODS:...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
Background and purpose: Recurrent implantation failure is one of the problems associated with in vitro fertilization cycles. The aim of this study was to evaluate the results of pregnancy using intralipid infusion in infertile women with history of two implantation failures. Materials and methods: A clinical trial was conducted in 80 infertile women in the infertility center in Sari Imam Khom...
Angiotensin-converting enzyme inhibitors have been shown to improve splanchnic perfusion in distinct shock states. We hypothesized that enalaprilat potentiates the benefits of early fluid resuscitation in severe experimental sepsis, particularly in the splanchnic region. Anesthetized and mechanically ventilated mongrel dogs received an intravenous infusion of live Escherichia coli over a period...
The objective of the present study was to compare the success rate of extra-amniotic saline with traction on the cervix with folly catheter for termination of second trimester pregnancies. A randomized trial of extra-amniotic saline infusion versus traction on the cervix with folly catheter was performed on 200 patients with gestational age of 14-28 weeks who required induction of lab...
Introduction: It has been shown that repeated large volume paracenthesis associated with intravenous albumin infusion is a rapid, effective and safe therapy of massive ascites in cirrhosis. Our aim was to investigate wether IV infusion of albumin is necessary in large volume paeacenthesis therapy of cirrhotic ascites. Methods: 37 patients with tense cirrhotic ascites who were intractable to diu...
Objective(s): Propofol (2, 6-diisopropylphenol) is an intravenous anesthetic that is commonly used for the general anesthesia. It is well known that the spinal cord is one of the working targets of general anesthesia including propofol. However, there is a lack of investigation of the effects of propofol on spinal dorsal horn which is important for the sensory transmission of nociceptive signal...
Several techniques have been proposed to prevent hypotension in obstetric patients. Ephedrine and phenylephrine are individually used to prevent maternal hypotension; however, each has its own drawbacks. Some researchers have reported that the infusion of combined ephedrine and phenylephrine immediately after spinal anesthesia for cesarean delivery reduces the incidence of maternal hypotension....
