View clinical trials related to Hypotension.
Filter by:Hypotension after spinal anesthesia is associated with significant perioperative morbidity and mortality, especially in hypovolemic patients. Ultrasonographic measurement of internal jugular vein (IJV) has been recently shown as effective in predicting the intravascular volume status. The aim was to investigate the reliability of preanesthetic ultrasound measurements of IJV in predicting hypotension after spinal anesthesia.
Aim of this prospective observational study is to investigate whether shock index(SI), modified shock index(MSI) and age related shock index(ASI) have any predictive value in predicting post-spinal hypotension which may develop in patients over 65 years of age, who are planned to undergo transurethral resection of the prostate (TURP) and transurethral resection of the bladder (TURB) surgery under spinal anesthesia.
The goal of this study is to evaluate if vasopressin can elevate systemic arterial blood pressures without having a significant effect on pulmonary arterial pressures. Because patients who have undergone Fontan procedures rely on low pressures across the pulmonary vascular bed to maintain cardiac output, vasoactive agents that concomitantly increase systemic and pulmonary pressures may have a deleterious effect in this specific patient population. Hypothesis: In patients with Fontan physiology, vasopressin will increase systemic BP by 20% above baseline, without increasing the transpulmonary gradient.
Study of the impact of preoperative oral rehydration on the incidence of spinal anesthesia-induced hypotension for scheduled cesarean section.
Vasoplegic syndrome is characterized clinically by reduced systemic vascular resistance and normal or increased cardiac output. It is principally observed in cardiovascular and orthopedic interventions and is characterized by a systemic inflammatory response with the inability of the vascular endothelial muscles to contract and a resistance to the action of vasoactive drugs. This event extends the length of stay in the critical care area due to the need of vasoactive drugs. The investigators aim to assess the standardized application of midodrine in postoperative patients without sepsis and need of vasoactive drugs in order to reduce the length of stay in critical care area and for extension in hospital.
Comparision of Exposed Factors of Preoperative Hypertension and Intraoperative Controlled Hypotension on Postoperative Delirium in the Elderly under Radical Resection of Head, Neck and Maxillofacial Tumor
The purpose of this observational research study is to examine how point-of care ultrasound affects the workup and management of perioperative complications for specific clinical scenarios of low blood pressure (hypotension), low blood oxygen (hypoxemia), in the post- anesthesia care unit (PACU).
This will be a randomized study aiming at investigating the combination of a norepinephrine infusion and colloid preloading versus the combination of a norepinephrine infusion and crystalloid co-loading for the prevention of maternal hypotension during elective cesarean section
This will be a double-blind randomized study, aiming at investigating a fixed rate phenylephrine infusion versus a fixed rate norepinephrine infusion versus placebo in combination with co-hydration with colloids for the prevention of maternal hypotension in elective cesarean section
This is prospective randomised double blind study conducted in parturients planned for non-elective caesarean section under spinal anaesthesia. Glycopyrrolate group will receive 0.2 mg of Glycopyrrolate before start of phenylephrine infusion. Control group will receive 0.2 ml of Normal Saline before start of phenylephrine infusion. Total amount of vasopressors required i.e. ephedrine or phenylephrine will recorded in the form of phenylephrine equivalent during intraoperative period.
