Filter by:Anesthesia reduces blood pressure and cerebral blood flow is normally considered to be maintained despite marked changes in blood pressure. Vascular surgical patients are often elderly, have high blood pressure and atherosclerosis and in these patients cerebral blood flow may decrease if blood pressure is reduced during anesthesia. The purpose of this study is to assess the effect of blood pressure for preservation of cerebral blood flow during anesthesia in vascular surgery. The hypothesis is that in vascular surgical patients, during anesthesia, cerebral blood flow is higher with blood pressure maintained at a higher level than that used in normal clinical practice.
Maintenance of analgesia during a patient stay in the hospital has been an important area of investigation after demonstrating a direct correlation between level of sedation and mortality in the ICU setting. This study will investigate the use of accelerometers in determining patient sedation level.
This study investigates the use of remimazolam as a sedative/hypnotic in general anesthesia. Remimazolam or propofol will be administered together with fentanyl/sufentanil/remifentanil as opioid analgesics and a neuromuscular blocker. In total, 530 patients will be randomized. This group of 530 patients will be split randomly into 2 groups as follows: • 106 patients will be randomized to induction with propofol plus fentanyl or sufentanil or remifentanil and a neuromuscular blocker. Throughout maintenance, the patients will receive propofol and remifentanil until weaning from the mechanical ventilation on the ICU or PACU within 24 hours after induction. Afterwards, sedation with propofol as study medication has to be ended. If necessary, the sedation is to be continued with the hospital's own supplies (propofol or other sedative). • 424 patients will be randomized to induction with remimazolam 6.0 mg/kg/hr together with fentanyl or sufentanil or remifentanil and a neuromuscular blocker. Throughout maintenance, the patients will receive remimazolam and remifentanil until weaning from the mechanical ventilation on the ICU or PACU within 24 hours after induction. The primary endpoint is successful sedation is defined as a Narcotrend index of 60 or less during at least 85% of the maintenance time and no rescue sedative medication administered. The maintenance starts at arrival at the operation theater and ends with the completion of the last skin suture.
Investigators studied 15 patients scheduled for pulmonary resection through thoracotomy. Initial tidal volume (VT) 10ml kg-1 was reduced to 8ml kg-1 after one lung ventilation (OLV) and the rate adjusted to maintain partial pressure of arterial carbon dioxide (PaCO2) 30-35 mm Hg. Data were obtained at: T1, 15 min post establishing OLV with normocapnia, T2, 15 min post establishing OLV with hypercapnia (PaCO2 7.98kPa (60mmHg) and 9.31kPa (70mmHg) and pH >7.1), and T3, 15 min after resuming OLV with normocapnia. One-way repeated measures analysis of variance (ANOVA), with post hoc Dunnet´s test were used for analysis. A P value < 0.05 is considered statistically significant.
The purpose of this study is to determine the effects of pain on facilitating long-term auditory memory in the presence and absence of distinct intravenous anesthetics. The ability to identify previously presented words from a list assessed the degree of memory formation. In a subset of subjects, functional magnetic resonance imaging was used to identify the neural correlates of memory inhibition or facilitation by the combination of pain and anesthetic used.
The Anesthesia Quality Institute (AQI) is home to the National Anesthesia Clinical Outcomes Registry (NACOR), a data warehouse that has been designated as a Qualified Clinical Data Registry (QCDR) by the Centers for Medicare and Medicaid Services (CMS) for Physician Quality Reporting System (PQRS) reporting. With 20 million cases and growing, Anesthesia Quality Institute's clinical data provides an evidence-based rational that informs treatment choices and helps control treatment costs. National Anesthesia Clinical Outcomes Registry is intended for all anesthesia providers caring for patients. The registry provides participating providers with: Custom continuous performance monitors Performance gap analysis and patient outlier identification Access to improvement interventions to close performance gaps including patient care management tools, targeted education, resources and other evidence based interventions Registry and peer-to-peer benchmarks
The present study is a pilot study aiming to compare the variation in core temperature (measured through the non-invasive device Spot-OnTM3MTM) in patients submitted to neuraxial anesthesia for orthopedic procedures, during sedation with midazolam vs propofol.
Overinflation of laryngeal mask airway cuff increase side effect like hoarseness, vocal cord paralysis, sorethroat. The investigators will study correlation between laryngeal mask airway cuff volume and pressure and physical examination of head and neck.
General anesthesia lowers FRC thereby promoting airway closure and absorption atelectasis. Alveolar recruitment manoeuvers recruit collapsed alveoli, increase gas exchange, and improve arterial oxygenation.
The purpose of the study was to investigate the effects of etomidate or sevoflurane used in electroconvulsive therapy (ECT) on duration of seizure, hemodynamic response and recovery profiles.
