Association of remimazolam with delirium and cognitive function: A systematic review and meta-analysis of randomised controlled trials.

Background And Study Objective: Delirium is an organic mental syndrome significantly associated with long-term cognitive decline, increased hospital stays and higher mortality. This systematic review of randomised controlled trials (RCTs) with meta-analysis assesses the association of remimazolam with postoperative cognitive function and delirium compared with non-benzodiazepine hypnotics.

Design: Systematic review of RCTs with meta-analysis.

Effect of Volatile Anesthetics on Myocardial Infarction After Coronary Artery Surgery: A Post Hoc Analysis of a Randomized Trial.

Objective: To investigate the effect of volatile anesthetics on the rates of postoperative myocardial infarction (MI) and cardiac death after coronary artery bypass graft (CABG).

Design: A post hoc analysis of a randomized trial.

Setting: Cardiac surgical operating rooms.

[New oropharyngeal double lumen cannula for sedation for transesophageal echocardiography: case series].

Introduction: Currently, transesophageal echodopplercardiography is frequently performed under sedation on an outpatient basis. Sedation is related with increase in incidents on airways. Bearing in mind this scenario, we developed a new double lumen oropharyngeal cannula aimed at keeping airway patency, in addition to reducing risks to patients during endoscopy procedures performed under sedation.

Development of a prototype anti-pollution filter for volatile anesthetics.

Introduction: The use of volatile agents during cardiopulmonary bypass allows a "single drug anesthesia" and is associated with reduced peak postoperative troponin levels. Connecting the exhaust systems to the oxygenator's gas outlet port is mandatory and allows to prevent operating room (but not atmospheric) pollution by volatile agents. The aim of this study was to create a prototype filter for volatile agents and to test its adsorption efficacy during an ex-vivo simulated conventional cardiopulmonary bypass test.

[Inhalational anesthesia maintenance with the Janus facial mask for transcatheter aortic-valve replacement: a case series].

Background And Objectives: Aortic stenosis is the most common type of heart valve disease. Percutaneous aortic valve replacement has become the alternative for patients considered at high risk for surgery. Controlled mechanical ventilation with tracheal intubation has been the choice for this type of procedure, however the use of noninvasive ventilation in cardiac patients has shown to be beneficial.

[Thiobarbituric acid reactive substances as an index of lipid peroxidation in sevoflurane-treated rats.].

Background And Objectives: Sevoflurane is a fluorinated ether with low blood solubility and biotransformed by an oxidative enzymatic liver system involving cytochrome P450 2E1. Lipid peroxidation occurs during ethers biotransformation process under action of cytochrome P450, a possible mechanism for liver and kidney toxicity promoted by such compounds. This study aimed at determining the levels of substances reactive to thiobarbituric acid (TBARS), as an index for lipid peroxidation in sevoflurane-treated rats, previously treated or not with isoniazid, enzymatic inducer of cytochrome P450 2E1.
