Active clinical trials for "Hypotension"

The incidence of hypotension perioperatively during operation of an acute hip fracture is unknown. As a surrogate factor the usage of vasopressor support is more adequate as the registration of vasopressor drugs are many times not complete in records. The investigators retrospectively investigated the anesthetic journals of 1100 patients with an acute hip fracture (AHF) noting confounding factors and the usage of vasopressors either by injections or infusions and then correlated these results to mortality at 30-, 90- and 365- days

Prospective trial including full term parturients scheduled for a cesarean section under spinal anesthesia. patients are being randomly assigned into 2 groups: LE group: will be positioned in 15° left tilt with leg elevation with a 30cm height pillow under the heels, this position will be hold after spinal anesthesia until fetal extraction. Control group: will be positioned in supine with 15° left tilt. the 2 groups will receive a 10ml/kg of crystalloid co-load intravenously, and the spinal anesthesia will be performed in sitting position with the same dose of Bupivacain, morphine and sufentanil.

The perfusion index (PI) is a numerical value for the ratio between pulsatile and non-pulsatile blood flow measured by a special pulse oximeter. PI represents the baseline sympathetic tone which is assumed one of the factors contributing for hypotension. Patients with low PI were reported by Mahendale and Rajasekhar to show greater hypotension after induction of anesthesia. This was explained by the high sympathetic tone in these patients which is suddenly masked by propofol administration leading to profound hypotension. This study aims to evaluate the ability of preoperative plethysmographic variability index, perfusion index and the Dicrotic Plethysmography to predict post-induction hypotension.

During general anesthesia, hypotension might occur during positional change. It is reported that hypotension after positional change from supine to prone is mainly caused by the decrease in preload. The investigators aimed to investigate whether dynamic arterial elastance might predict hypotension associated with positional change from supine to prone.

The induction of anaesthesia is one of the most critical situations for high-risk-patients undergoing interventions surgery. For several reasons, it is crucial to maintain adequate blood pressure and cardiac output during this phase. This retrospective cohort study aims to find out if the choice of the induction agent has a major impact on blood pressure and the use of catecholamines during the induction and the interventional procedure in patients undergoing interventional mitral valve repair.

Children generally undergo induction of anesthesia by inhalation of sevoflurane. Children with Down Syndrome experience bradycardia with induction of anesthesia using sevoflurane. It is unknown if this bradycardia is isolate or results in hypotension, thus requiring treatment. Isolate bradycardia without hypotension does not require treatment and should be avoided as many of these patients have underlying cardiac anomalies.

The primary objective of the study is to provide access to LJPC-501 for distributive shock patients who remain hypotensive despite receiving fluid and vasopressor therapy.

The primary aim is to establish whether breastfeeding is associated with lowering blood pressure in hypertensive women.

The purpose of this study is to find out the predictability of the pulse pressure variation during spontaneous ventilation on the incidence of hypotension during induction of anesthesia.
