Filter by:Continuous perioperative cardiac output (DC) and blood pressure (PA) monitoring contributes to hemodynamic stability and ensures adequate perfusion pressure, resulting in a reduction in morbidity and mortality and length of hospital stay. The monitors usually used in perioperative are either semi-invasive and difficult for calibration (oesophageal Doppler) or invasive (arterial catheter). The Nexfin HD allows these two measurements and it is completely non-invasive, remains to validate its use in peroperative.
This prospective and observational cohort studies the morphine consumption difference during the first 48 hours after a lung lobectomy between patients operated with a robot assisted or a video-assisted technique for a lung cancer lobectomy. Second outcome was to search eventual cardiac output difference during the surgery in 100 patients (50 in each group) using a non invasive monitoring device of cardiac output All patients operated between january 2016 and March 2017 for a lung cancer lobectomy were included.
The aim of the study is to investigate the effect of different angles of lateral tilt on the maternal hemodynamics before and after spinal anesthesia
Spinal block leads to the reduction of systemic vascular resistance (SVR) which may effect the cardiac output. Ngan Kee et al. has showed that spina block with 0.5% hyperbaric bupivacaine for Cesarean section combined with intravenous infusion norepinephrine had higher cardiac output than those who received phenylephrine
Evaluation of a non-invasive technique to measure cardiac output (esCCO™) with the "clinical goldstandard" of the transcardiopulmonal thermodilution technique (PiCCO®). Effect of different potential interference factors to the accuracy of measurement (changing concentration of norepinephrine, generally severity of the basic disease - APACHE II score).
The aim of the present study is to compare accuracy and precision of Cardiac Output (CO) by nine different pulse contour algorithms with transpulmonary thermodilution before and after cardiopulmonary bypass (CPB).
Compromised peripheral tissue oxygenation during surgery may lead to worse patient outcome, mainly due to post-operative infections or heart failure. Insufficient stroke volume and/or cardiac output due to hypovolemia or cardiac defects play a central role in causing poor peripheral tissue oxygenation. In order to assess stroke volume, there are numerous invasive and non-invasive methods available. Up to the present date it is unknown, if these methods may by used interchangeably in patients with severe cardiac defects like aortic stenosis.
Ondansetron is a medication routinely given to mothers having cesarean deliveries to help prevent and treat nausea and vomiting. The investigators are studying the hemodynamic effects of prophylactic ondansetron on parturients undergoing elective cesarean deliveries under spinal anesthesia.
A study to determine if echocardiographically derived parameters, plethysmographic variability index and pulse pressure variation predict fluid responsiveness in children on PICU.
Recent occurrence of significant post-operative liver impairment at Nottingham University Hospitals NHS Trust has prompted investigation into whether interaction between general anaesthesia and prone positioning (lying face down) for surgery can influence liver function. Historical research has shown that the heart does not function as efficiently when an anaesthetised patient is placed in the prone position for surgery. The techniques used for anaesthetising and monitoring these patients have changed remarkably, since these studies were first performed. It is important to know accurately how the heart functions to enable better understanding of the changes in blood flow to the liver when in the prone position. Studies looking at blood flow to the liver when lying face down have been done before but are mainly reporting patients on the intensive care unit. These intensive care patients are different to those in theatre undergoing routine surgery. The intensive care patients are usually received in different types of drugs and monitored with several different types of monitor at the time. Perhaps most importantly is that they are placed face down on a soft air cushioned mattress and pillows rather than the rigid support used for surgical patients. This study will look at whether the function of the liver changes when a patient is anaesthetised and is then rolled onto their front. The function of the liver will be measured by looking how it clears a specific drug from the blood. Also this study will look at how accurate a particular type of heart monitor is when an anaesthetised patient is placed onto their front.
