NCT ID: NCT03168126 Completed - Fluid Overload Clinical Trials

Advanced Hemodynamic Monitoring in Free Flap Surgery

AHM
Start date: January 2014
Phase: N/A
Study type: Observational

Background: Anesthesia in free flap surgery is challenging. Monitoring of hemodynamic changes and their influence on the cardiovascular system in permanent feedback loops allow control, which is what anesthesiologists aim for to ensure an adequate blood flow and tissue oxygenation. The circulatory support and inferable volume administration are managed via heart rate (HR) and mean arterial pressure (MAP), but both parameters are influenced by variable components and are thus unfavorable for volume management. The aim of this study was to evaluate whether volume requirement may be assumable to additional monitoring parameters. Methods: 31 patients were enrolled prospectively. HR, MAP, central venous pressure and O2 saturation were comprehended based on the protocols. We expanded the data set by a permanent blinded intraoperative monitoring with registration of the Cardiac Index (CI) and Stroke Volume Variation (SVV) and semi-invasive pulse-contour analysis utilizing the Pro-AQT-Device.

NCT ID: NCT03008785 Completed - Bloodpressure Clinical Trials

Effect of Isoflavone Supplementation Associated With Physical Exercise in the Health Parameters of Postmenopausal Women

Start date: February 2015
Phase: N/A
Study type: Interventional

This study evaluate if 10 weeks of mixed exercise combined with isoflavones could have greater effects on climacteric symptoms, body composition and hydratation, lipidic and inflamatory profile than exercise alone in postmenopausal women. the participants will be randomly assigned to the group: placebo and exercise or 100mg of isoflavone and exercise.

NCT ID: NCT02997800 Completed - Heart Rate Clinical Trials

The Effect of Intraoperative Labetalol on Time to Discharge

Start date: November 2012
Phase: Phase 2
Study type: Interventional

Patients coming for surgery often receive opioid medications, like fentanyl, to treat pain. Opioids however have many unpleasant side effects including nausea and vomiting, itching, sedation, and decreased breathing. During laparoscopic surgery increases in heart and blood pressure are often attributed to pain. It has been shown that by treating these changes with medications such as esmolol, instead of opioids, side effects and time to discharge from hospital can be reduced. Labetalol is a drug that is similar to esmolol but may have advantages over it. It is more effective at controlling both heart rate and blood pressure and it is easier and less costly to use. This study is investigating labetalol in patients having laparoscopic gallbladder surgery and comparing it to esmolol and fentanyl. Patients will be treated with one of these drugs during surgery to control heart rate and blood pressure and the effects on time to discharge, pain scores, frequency of side effects, and narcotic requirements will be observed in the recovery room. It is thought that labetalol will be shown to be as effective as esmolol and that both drugs that minimize fentanyl will show reduced time to discharge, fewer side effects, and effective treatment of heart rate and blood pressure.

NCT ID: NCT02038270 Completed - Bloodpressure Clinical Trials

Accuracy of Nexfin® and NIBP to Predict IBP

Start date: September 2011
Phase:
Study type: Observational

The Nexfin monitoring device relies on noninvasive pressure measurement using a finger-cuff manometer, combined with NIRS technology. The accuracy of the signal is dependent on the degree of vascular unloading, which takes an period before optimal unloading is reached. The evolution of the degree of inaccuracy caused by inclomplete unloading is quantified, and the absolute and relative inaccuracy of the nexfin as a function of the time is determined compared to the invasive blood pressure (IBP). Secondly, the accuracy of the Nexfin to predict the IBP is compared with the accuracy of noninvasive blood pressure to predict the IBP.

NCT ID: NCT01609491 Completed - Bloodpressure Clinical Trials

Phenylephrine Versus Norepinephrine in Ophthalmic Surgery

Start date: January 2012
Phase: N/A
Study type: Interventional

In ophthalmic surgery the specific anaesthesiological challenges necessitate the administration of a combination of relatively high doses of hypnotics and analgetics. In order to preserve adequate organ perfusion, there is often a need to administer pharmacological agents for haemodynamic support. Depending on the experience of the anaesthetist a continuous infusion of phenylephrine or norepinephrine is used. It is currently not known which of these agents has the most favorable haemodynamical profile. Haemodynamic parameters (continuous blood pressure, cardiac index, stroke volume and systemic resistance), peripheral tissue oxygenation and cerebral tissue oxygenation will be monitored noninvasively using the Nexfin® , Inspectra®, and Foresight® and O2C® monitoring devices.
