Induction Agent and Incidence of Hypotension in Heart Failure Patients Undergoing LVAD-Implantation...
Blood PressureLowThe induction of anesthesia is one of the most critical situations for high-risk-patients undergoing major surgery. For several reasons, it is crucial to maintain adequate blood pressure and cardiac output during this phase. This observational study aims to find out if the choice of the induction agent has a major impact on blood pressure and the use of antihypotensive drugs during the induction and the surgical procedure in heart-failure patients undergoing the implantation of a left ventricular assist device (LVAD).
Prediction of Risk of Hypotension in Hemodialysis
Chronical Kidney DiseaseHypotension2 moreThe main objective is to establish a statistical predictive model of the risk of intradialytic hypotension during hemodialysis (HD) or hemodiafiltration (HDF) sessions based on the measurement of residual blood volume and excess extracellular hydration. The secondary objective is to study the impact of dysfunction in the mechanisms of compensation for decreased blood volume (heart disease, neuropathy, drugs) on the risk of intradialytic hypotension.
Ability of Carotid Sonography and Inferior Vena Cava Sonography for the Prediction of Post-induction...
General AnesthesiaHypertensive patients have more hemodynamic instability during general anesthesia than do patients with NORMOTENSION. In this study, the investigators evaluated the usefulness of carotid ultrasound and inferior vena cervical ultrasound for predicting hypotension after induction of anesthesia in patients with hypertension.
Is Orthostatic Hypotension Associated With Nondipping Hypertension
Orthostatic HypotensionNondipping HypertensionThe aim of the study is to evaluate whether orthostatic hypotension is associated with nondipping hypertension. Methods and patients: 400 subjects who are referred for 24hABPM will be filled questioner regarding their medical background and medications. All patients will be subjected to orthostatic test before connection to the 24 ABPM. The orthostatic changes in blood pressure and heart rate will be correlated to the changes in blood pressure and heart rate from day to night as recorded by the 24H ABPM.
IVC Ultrasonography Versus Plethysmographic Variability Index for Prediction of General Anesthesia...
Hypotension on InductionThis thesis aims to evaluate the ability of preoperative plethysmographic variability index to predict post-induction hypotension in comparison with ultrasound measurements of inferior vena cava (IVC) diameter.
IDH in Diabetic Haemodialysis Patients and Association With Dialytic Age
Intra-dialytic HypotensionIntradialytic hypotension (IDH ) is a serious and the most frequent complication of hemodialysis of the hemodialysis .Diabetes is associated with autonomic neuropathy which contribute to intradialytic hypotension
Validation Study in Patients of a Non-invasive Blood Pressure Monitor for Perioperative Use
Intraoperative HypotensionCollecting all available data (waveforms, beat to beat data, status data) generated by a non invasive blood pressure monitor on each hand and compare this to the actual data obtained by intra arterial (radial) monitoring. This to see if the non invasive bloodpressure monitor can be validated for intraoperative use.
Focussed Echocardiography to Detect Preoperative Hypovolemia and Left Ventricular Dysfunction as...
HypotensionThis is an observational study to evaluate the role of a Bed side Focus assessed Transthoracic Echocardiography (FATE) in identifying the patients at a potential risk of developing hypotension secondary to general anesthesia induction using the FATE parameters like velocity time integral ( VTI ), Inferior venacava diameter , Caval index and Left ventricular end end diastolic area.
Prediction of Hypotension During Beach Chair Position Using Pleth Variability Index
HypotensionThe beach chair position for shoulder operation induces hypotension during general anesthesia. Hypotension is induced by decreased preload and contractility due to anesthesia. Masimo is a pulse oximetry which shows pleth variability index noninvasively. The pleth variability may predict the hypotension during beach chair position.
Ultrasonic Measurement of IVC and IJV in Predicting Hypotension After Anesthesia Induction
AnesthesiaThis research is expected to study ultrasonic measurement of internal jugular vein and inferior vena cava, which can be used as a good index to predict hypotension after anesthesia induction, and its measurement method is simple and quick.
