Filter by:The researchers are trying to determine pain medication consumption in the first 24 hours after surgery in patients given the standard continuous infusion of local anesthetic versus patients given the same total dose via programmed intermittent dosing. Both groups will receive the option of patient controlled pain medication as well as the same dose of pre-programmed pain medication. The only difference is the rate of administration: continuous vs. hourly intervals.
Many intrathoracic procedures demand optimal collapse of the operative lung to facilitate surgical exposure. Single-lung ventilation can be achieved using a double-lumen tube (DLT), a Univent tube, or an independent bronchial blocker. Insertion of a DLT using a direct laryngoscope can be more difficult than that of single-lumen tube (SLT), especially in patients for whom airway difficulty is anticipated. The safest of the proposed methods involves the placement of an SLT with the aid of an fibreoptic bronchoscope (FOB), following which the SLT is replaced with a DLT using an airway exchange technique in these patients. HumanBroncho® (Insung Medical, Seoul, Korea) is a new silicone DLT with a soft, flexible, non-bevelled, wire-reinforced tip. The oval shape, obtuse angle, and short lateral internal diameter of the bronchial lumen and its flexibility may allow for advancement to the trachea over the FOB with as much as ease as a standard SLT. In the present study, the investigators aimed to test the hypothesis that the HumanBroncho® DLT would be non-inferior to a standard SLT with regard to intubation time over an FOB in patients with semi-rigid neck collar simulating difficult airway.
Automated delivery of propofol using computer-controlled closed loop anaesthesia device delivers propofol based on patient's frontal cortex electrical activity as determined by bi-spectral index (BIS). Evaluation of anaesthesia delivery by these systems has shown that they deliver propofol and maintain depth of anaesthesia with far more precision as compared to manual administration. By automatically controlling anaesthesia depth consistency they provide time to the anaesthesiologist to focus on other aspects of patient care such as managing intra-operative hemodynamics and ventilation perturbations during major surgeries. Closed loop anaesthesia delivery system (CLADS) is an indigenously developed continuous automated intravenous infusion system which delivers propofol based on patients EEG profile (BIS) feedback. Although a few studies have already evaluated these automated systems in patients undergoing thoracic surgery, but suffered from significant limitations (small number of patients, not dedicated to thoracic surgery cohort). Currently, there is no data available regarding CLADS performance vis a vis adequacy of GA and haemodynamic profile in patients undergoing thoracic surgery. We contend that propofol as delivered by CLADS will proffer greater consistency to anaesthesia depth, intra-operative hemodynamic stability, and rapid recovery upon anaesthesia discontinuation than manual means of delivering propofol TIVA. This randomised controlled study aims to compare the efficiency of CLADS-driven propofol TIVA versus manually controlled propofol TIVA in patients undergoing thoracic surgery.
Collect real-world clinical and device-specific outcomes of the GORE® TAG® Conformable Thoracic Stent Graft featuring ACTIVE CONTROL System (CTAG Device with ACTIVE CONTROL) in the treatment of aortic disease as part of routine clinical practice.
A technique not yet described in the literature and allowing anesthesiologists who do not regularly practice fibroscopy or who do not routinely have this type of apparatus for their procedures, to install straight double-lumen tubes without compromising the ventilation of the patient. The aim is to introduce a central venous catheter wire guide into the bronchial arm of the right double-lumen tube and insert it into the right upper lobe bronchus orifice under fluoroscopic control. Then, to validate the new technique, we will carry out a fibroscopic control.
Prospective randomized double blind phase IV trial studying the efficacy and safety of the tonicity of two different perioperative maintenance solutions: an isotonic solution containing NaCl 0.9 in glucose 5% with an added 40 mmol/L of potassium or a commercially available premixed solution (Glucion 5%) containing a.o. 54 mmol/L of sodium and 26 mmol/L of potassium. Both solutions are administered at 27 mL/kg of ideal body weight, as recommended by current guidelines (NICE 174) and both solutions are widely used in daily clinical practice. The primary hypothesis is that isotonic maintenance solutions lead to more fluid retention than hypotonic fluids. Metabolism of both solutions is assessed by sequential analysis of urine and serum and clinical parameters.
The aims of the study are to compare the effectiveness and postoperative outcomes of liposomal bupivacaine vs plain bupivacaine following video-assisted thoracoscopic surgery. The investigators' hypothesis is that liposomal bupivacaine will decrease the postoperative pain and will be associated with more favorable postoperative outcomes when compared to plain bupivacaine following video-assisted thoracoscopic surgery.
The B vitamin biotin is widely available as an over the counter supplement, often advertised and used to promote health of hair, skin and nails. Commercially available over the counter biotin supplements contain dose ranges up to 10 mg/day (ie 333 times higher than the recommended dietary allowance). The biotin molecule is also sometimes used as part of the lab technology to measure hormone and protein levels in the blood. It is possible that high doses of ingested biotin may interfere with accurate hormone or protein measurement using biotin related in vitro measurement systems. Such interference, if present, could lead to misdiagnosis. The study will analyze laboratory levels obtained with streptavidin-biotin assay systems while ingesting biotin in currently available high dose supplements. The data will be compared to measurements obtained prior to and one week after stopping the biotin supplement.
The purpose of this study is attempt to establish optimum drive pressure of high frequency jet ventilation during rigid bronchoscopy to ensure good aeration of the lungs examined by electrical impedance tomography.
