Effective Volemia in Older Adults

Orthostatic Hypotension

Clinical and biological assessments of volemia are challenging in older patients as they are more likely to present non-typical signs. Point of care ultrasonography (POCUS) using heart and lung exploration is a relevant tool to assess volemia in adults with little data in older adults. The primary objective of the study is to evaluate feasibility of positional POCUS in aging patients. The secondary objectives are to assess the variability of measurements between decubitus and sitting position.

HOW DOES HEMODYNAMIC REGULATION AFFECTS GRAFT FUNCTIONS DURING RENAL TRANSPLANTATION?

Renal Transplant Failure and RejectionHypotension

The aim of the researchers was to evaluate the adequacy of graft function in the postoperative period of patients who underwent renal transplantation and encountered hypotension in the intraoperative period.

Pressure Recording Analytical Method Parameters in Hypertensive Patients

Cardiovascular DiseasesSurgery3 more

Perioperative anesthesiologists can benefit from easily obtainable hemodynamic variables detecting or quantifying the lack of an adequate compensatory capacity of the cardiovascular system in order to optimize patient management and improve patient outcomes. Parameters of the Pressure Recording Analytical Method (PRAM; Vygon, Padua, Italy) of the MostCare system, specifically cardiac cycle efficiency has been proposed as such variables. Yet, their value in anesthesia and especially in hypertensive patients is not studied. The goal of the PRAM-in-HYPO study is to prospectively evaluate the relationship between cardiac reserve and efficiency and cardiovascular risk factors in patients wo will undergo major surgical procedures using the state-of-the-art hemodynamic monitors. Also the investigators aim to build a predictive model to identify patients with decreased cardiac reserve due to hypertension and other cardiovascular risk factors, who are susceptible to post-induction hypotension. The investigators seek to include high-risk patients or patients presenting for major surgery, who are monitored with an advanced hemodynamic monitor to adequately evaluate the differences in cardiac reserve and cardiac efficiency.

Breathing Device for Orthostatic Hypotension (OH)

Orthostatic Hypotension

The investigators will test whether breathing through an inspiratory resistance device will improve the ability to be upright and decrease blood pressure drops on standing in patients with orthostatic hypotension.

The Ability Of Inferior Vena Caval Distensibility Index With Passive Leg Raising Test To Predict...

Spinal Anesthetics Causing Adverse Effects in Therapeutic Use

Many previous studies have investigated the ability of various methods such as passive leg raising test , and inferior vena cava collapsibility index in predicting post-spinal hypotension, but none of them have succeeded in obtaining a good predictive value. Our study aims to combine the passive leg raising test with the inferior vena cava distensibility index to aid in predicting post-spinal hypotension in elderly undergoing infra-umbilical surgeries.

Colloid Preload Versus Crystalloid Co-load in Cesarean Section Under Spinal Anesthesia

Hypotension

Comparison between colloid preload and crystalloid co-load in cesarean section under spinal anesthesia. The primary outcome was the incidence of hypotension Secondary outcomes included the incidence of severe hypotension, total ephedrine dose, nausea and vomiting and neonatal outcome assessed by Apgar scores and umbilical artery blood gas analysis

Impact of GDT in Robot-assisted Laparoscopic Urological Surgery for Low to Moderate Risk Patients...

Vascular HypotensionHypovolemia1 more

Robot assisted urological procedures are often long surgical cases that can potentially result in complicated postoperative hospital course. The amount of intravenous (IV) fluids administered to patients during these operations fluctuates based on the length of the case, surgical blood loss, hemodynamic monitors, and the discretion of the anesthesiologist. The goal of intraoperative fluid therapy is to maintain optimal tissue perfusion without causing fluid overload. We plan to use a goal directed fluid therapy protocol to optimize fluid status and analyze post-operative outcomes.

Extra Sitting Time After Spinal Anesthesia for Cesarean Section and Fetal Well-being

Complications; Cesarean SectionHypotension

After injection of the spinal anesthetic drug, women will be allowed to lie down immediately (0-30 sec) or after three minutes (180 sec) of sitting. The incidence of maternal hypotension and fetal umbilical cord blood pH will be recorded.
