Filter by:Intraoperative hypotension (IOH) is a sudden clinical phenomenon that occurs frequently during general anesthesia. Prevention of IOH has been linked to reduced postoperative organ damage and decreased incidence of perioperative complications. Oncological patients with reduced preoperative physiological reserves may be especially vulnerable to IOH deleterious effects, especially when exposed to prolonged surgical time increase, as it is the case for patients undergoing pancreatic surgery. The investigators aim to study introduction of a new technology able to predict hypotensive events (Hypotension Predictive Index, HPI Acumen™) in terms of its effects on IOH occurrence and burden in patients undergoing pancreatic surgery. The investigators will enroll patients before and after the introduction of HPI monitoring. Further, differences in postoperative outcomes and perioperative complications between before and after populations will be investigated.
Subarachnoid block is the common route of anesthesia for cesarean delivery. Maternal hypotension after subarachnoid block is very common despite the vigorous methods for its prevention. Maternal hypotension is sometimes deleterious to the mother and the fetus; thus, it is highly recommended to use prophylactic vasopressors directly after the block and before the blood pressure drops. The aim of this work is to compare the maternal and neonatal effects of epinephrine and phenylephrine when used as prophylactic infusion after subarachnoid block for cesarean delivery.
The parturients may suffer from hypotension after spinal anesthesia and the incidence could be as high as 70-80% when pharmacological prophylaxis is not used. Acupuncture was reported to treat hypotension both in human and animal studies. Possible mechanisms include modulating cardiovascular and sympathetic system. In this prospective, double-blinded, randomized clinical trial, we tend to investigate the effect of transcutaneous electric acupoint stimulation (TEAS) on hypotension in parturients undergoing cesarean section.
Intraoperative hypotension is linked to increased incidence of perioperative adverse events such as myocardial and cerebrovascular infarction and acute kidney injury. Hypotension prediction index (HPI) is a novel machine learning guided algorithm which can predict hypotensive events using high fidelity analysis of pulse-wave contour. Goal of this trial is to determine whether use of HPI can reduce the number and duration of hypotensive events in patients undergoing major thoracic procedures.
In this study investigators will explore the association between intraoperative arterial hypotension and cerebral oxygen saturation in patients scheduled for major abdominal surgery. Investigators will assign patients to control or interventional group. In this last group arterial hypotension will be avoided based on a HPI (Hypotension Predictive Index) protocol. In the control group arterial hypotension will be promptly treated according to hemodynamic variables.
Research objective: To explore the safety and dose exploration of Remimazolam Tosilate for Injection for induction and maintenance of general anesthesia in elective short-term surgery in adults. Main research indicators:(1)Success rate of sedation during induction and maintenance of general anesthesia with remazolam tosylate;(2)The incidence and severity of hypotension in the induction and maintenance phases Study design: Multi-center, randomized, double-blind clinical study. Subject population: patients undergoing elective short-term surgery. Research data collection period: The subject signs the consent form until discharge or death in the hospital or withdrawal from the research. Number of research centers/sample size: It is planned to enroll 600 patients from 11 hospitals. Research process: The researchers will include patients who meet the enrollment criteria and agree to participate in the investigation of the support laryngoscope surgery and minor head and neck surgery patients from the elective surgery patients.
The study will investigate whether the use of Goal Directed Hemodynamic Therapy implemented with the HPI algorithm using a treatment algorithm will reduce the incidence of hypotension and improve treatment of hypotension.
