BACKGROUND As measurement of arterial oxygen saturation (SpO2) is common in the delivery room, target SpO2 ranges allow clinicians to titrate oxygen therapy for preterm infants in order to achieve saturation levels similar to those seen in normal term infants in the first minutes of life. However, the influence of the onset of ventilation and the timing of cord clamping on systemic and cerebral...
PURPOSE To evaluate glomerular injury in the rat model during renal warm ischemia (WI), comparing artery and vein (AV) clamping with artery only (AO) clamping. MATERIALS AND METHODS Twenty-four adult male rats underwent 60 minutes of renal WI in the left kidney. The animals were divided into three groups: AV clamping, AO clamping, and Sham surgery. After 30 days, the animals were euthanized, ...
Intraoperative epiaortic scanning for preventing early stroke after off-pump coronary artery bypass.
BACKGROUND Numerous studies have demonstrated the accuracy of epiaortic ultrasound scanning (EAS) for assessing ascending aortic disease. It remains unclear whether EAS changes the incidence of perioperative stroke after off-pump coronary artery bypass (OPCAB). METHODS We studied a retrospective cohort of 2292 patients who underwent isolated OPCAB from January 2001 to December 2011. Patients ...
Limited resection can be a therapeutic approach in patients with cirrhosis with very low remnant hepatic function after resection. In this study, two hilar vascular clamping methods (hilar selective clamping In 13] and hilar lobar clamping method In 8]), which were used for resection ofhepatocellular carcinoma in patients with cirrhosis, were compared based on cardiovascular stability during cl...
celiac artery aneurysm is a rare visceral aneurysm, comparising only 4 % of them. in this article, an innovative surgical method is presented for the treatment o f such aneurysms. a 53 year old female referred to our center with epigastric pain and a mass in the region, which was diagnosed as a case of celiac artery aneurysm by using different imaging techniques. during the operation, according...
conclusion we suggest the standard cefazolin prophylaxis (after cord clamping) for elective cesarean section and cefazolin before incision for non elective cesarean section. therefore, administration of prophylactic cefazolin prior to incision will not increase the rate of neonatal sepsis. compared between these groups. results two groups were demographically identical. rate of iv line need (rr...
OBJECTIVE To investigate the effects of delayed umbilical cord clamping, compared with early clamping, on infant iron status at 4 months of age in a European setting. DESIGN Randomised controlled trial. SETTING Swedish county hospital. PARTICIPANTS 400 full term infants born after a low risk pregnancy. INTERVENTION Infants were randomised to delayed umbilical cord clamping (≥ 180 second...
The optimal time to clamp the umbilical cord in preterm and full-term neonates after birth continues to be a matter of debate. A review of randomised controlled trials comparing the effects of early versus late cord clamping on maternal and infant outcomes was performed to assess data in favor of immediate or delayed clamping. Although there is no conclusive evidence, delayed cord clamping seem...
An Intelligent Fixturing System (IFS) is currently being developed to hold a family of thin-walled workpieces for machining operations. This is a cost-effective system which uses off-line optimisation of the clamps location and on-line adjustment of clamping forces. As adaptive clamping forces appropriate to the dynamic machining environment are employed, the IFS offers higher quality of machin...
