Filter by:The aim of the study is to analyze the variability of plethysmography curve depending on the breath cycle (respiratory rate and tidal volume).
The Pedra perfusion system will be used to assess changes in perfusion in response to physiological stimuli. It will be compared to other standard diagnostics.
The incidence of anastomotic leaks after gastroesophageal anastomosis after thoracolaparoscopic cancer esophagus surgery is high at the Oslo University Hospital. The patients selected for operation shall be investigated for microcirculatory changes at the thoracic anastomosis site and followed up for any post operative anastomotic leaks.
The objective of this study is to evaluate the performance of Modulated Imaging Inc.'s (MI) next generation Spatial Frequency Domain Imaging (SFDI) system to measure potential circulatory compromise.
Hepatocellular insufficiency is a dreaded complication after hepatectomy, since, if it is persistent, it leads to the death of the patient in the absence of liver transplantation. The preoperative evaluation aims in particular to estimate the risk of postoperative hepatocellular insufficiency so as to minimize or contraindicate high-risk patients. It has been shown that the flow of the portal vein is correlated with liver function, especially in the living donor and after portal embolization. More recently, the study of flow rates in the portal vein and the hepatic artery after transplantation has shown a correlation with the recovery of graft function. The hypothesis is that portal and arterial flow after hepatectomy can predict postoperative hepatocellular function.
Aim of this study is to investigate the effects of increased intrarenal pressure during flexible ureteroscopy on renal blood flow. Patients undergoing flexible ureteroscopy (F-URS) and laser lithotripsy for kidney stones according to European Association of Urology (EAU) guidelines on Urolithiasis will be included in the study after having signed an informed consent form. The pre- and post-operative evaluation and management will be performed according to EAU Guidelines on Urolithiasis. Additionally, as a non-invasive test, bilateral renal power Doppler US will be performed to patients pre- and post-operatively. The pre-operative Doppler US will be performed 2 days prior to surgery and the post-operative Doppler US will be performed in the first 24 hours following surgery. The changes on blood flow in renal artery and arcuate artery will be recorded.
The aim of the present study is to assess the effects of brachial plexus block on microcirculation using pefusion index and capillary filling time.
To investigate if there are detectable changes in volume and circulation in breasts of healthy volunteers using toremifene 20 mg in luteal phase of the menstruation cycle versus nonmedicated cycle.
