Abstract Background Phase lag entropy (PLE) is a novel anesthetic depth indicator that uses four-channel electroencephalography (EEG) to measure the temporal pattern diversity in phase relationship of frequency signals brain. The purpose study was evaluate monitoring using PLE and correlation between bispectral index (BIS) values during propofol anesthesia. Methods In thirty-five adult patients undergoing elective surgery, anesthesia induced with target-controlled infusion (the Schneider...
Anesthesia machines have been developed by the application of new technology for rapid and easier control anesthetic concentration. In this study, we used a test lung to investigate whether time taken reach target sevoflurane concentration varies with rate fresh gas flow (FGF) type anesthesia machine (AM). We measured times (2 minimum alveolar = 4%) at variable rates FGF (0.5, 1, or 3 L/min) different types AM (Primus®, Perseus®, Zeus® [Zeus®-F; mode, Zeus®-A; auto-mode]). Concomitant...
Tracheal intubation using a double-lumen endobronchial tube (DLT) causes postoperative sore throat.To determine the effect of two-handed jaw thrust on throat in patients requiring insertion DLT.A randomised study.A tertiary teaching hospital from December 2017 to May 2018.One-hundred and six undergoing one-lung anaesthesia.Patients were allocated one two groups (n=53 each). In group, manoeuvre was applied at advancement DLT. control conventional with sham performed.Incidence 1, 6 24 h...
Malignant hyperthermia (MH) may lead to metabolic crisis of skeletal muscle in susceptible individuals following exposure triggering agents such as volatile anesthetics or depolarizing relaxants. MH is a rare and potentially lethal disease, which can cardiac arrest. We report case severe MH, the rapidly evolving signs hypermetabolism eventually resulted Despite conventional treatments cardiopulmonary resuscitation, patient's vital did not improve. Therefore, we applied extracorporeal...
Objectives/Hypothesis Laser microlaryngeal surgery (LMS) is a short operation requiring brief and intense paralysis. Adequate muscle relaxation rapid recovery of neuromuscular function are essential for improving surgical conditions reducing the incidence complications during LMS. However, ideal relaxant with onset duration action not yet available. Rocuronium has at higher doses, but prolonged action. Sugammadex selective relaxant‐binding agent that allows reversal rocuronium‐induced...
Objective The efficacy of chlorhexidine- and silver sulfadiazine-coated central venous catheters (CSS-CVC) against catheter-related infection remains controversial. We hypothesized that the loss nanoparticles may reduce antibacterial CSS-CVCs this could be due to frictional force between surface CVC bloodstream. objective study was investigate whether antimicrobial effect decreases with increasing exposure time in a bloodstream model quantitatively assay compared polyurethane...
Background: External applied pneumatic pressure is usually used for rapid transfusion of red blood cells (RBCs). However, increased shear stress can cause hemolysis and decreased RBC elongation indices. Therefore, the purpose this study was to measure degree alteration indices under varying external in fresh aged blood. Methods: Venous samples were obtained from 20 healthy human volunteers. Each bag divided into 2 subgroups (5 or 35 days storage), 5 levels applied: 0, 150, 200, 250, 300...
BACKGROUND: I-gelTM is a second-generation supraglottic airway device with non-inflatable cuff. In this prospective randomized investigation, we evaluated the effects of two-handed jaw thrust technique on i-gel insertion in anesthetized non-paralyzed patients.METHODS: Seventy-four adult patients were allocated to two groups (N.=37 each). group, was applied facilitate insertion. control conventional performed. The success rate at first attempt, air leakage pressure, time, and postoperative...
For patients undergoing endoscopic sinus surgery, intranasal injection of epinephrine can cause acute increases in heart rate and blood pressure.Among the drugs for reducing hyperdynamic effects, dexmedetomidine remifentanil are expected to blunt hemodynamic responses after epinephrine. Our study compared a difference 2 their abilities intraoperative period postoperative profile.In this study, were randomly divided into groups. During period, values recorded. The surgical condition was...
Real-time quantification of the patient's consciousness level during anesthesia is an important issue to avoid intraoperative awareness and post-operative side effects. A depth-of-anesthesia (DoA) monitoring method called Bispectral Index (BIS) generally used for this purpose. However, BIS known be inaccurate at transitory state, also shows a critical time delay in quantifying level. This paper introduces novel reduce response process. thesis develops new index HDoA by analyzing EEG using...
Penetrating neck injuries can be a fatal event and they are difficult to manage for both surgeons anesthesiologists. So, adequate preoperative evaluation is important improve the patients' outcomes, but this not done hemodynamically unstable or uncooperative patient. Here we present our clinical experience with patient penetrating injury who was stable, she knife still embedded in her neck. The surgical exploration bronchoscopic examination were successfully under monitored anesthesia care.
Objective To investigate the renoprotective effect of nicardipine in patients with pre-existing renal insufficiency undergoing robot-assisted laparoscopic radical prostatectomy (RALRP). Methods Men preoperative (estimated glomerular filtration rate [eGFR] <60 ml/min per 1.73 m 2 ) were enrolled and randomized to receive either 0.5 µg/kg min continuous infusion (nicardipine group) or normal saline (control during RALRP. Renal function was determined by eGFR serum creatinine concentration....
Background. The lumen of novel threadlike structures (NTSs) is enclosed by a single layer endothelial cells surrounded extracellular matrix (ECM). We hypothesized that collagen may be component the ECM associated with lymphatic NTSs. Methods. Six female New Zealand white rabbits were anesthetized, and NTS within vessels identified contrast-enhanced stereomicroscopy or alcian blue staining. Isolated specimens stained acridine orange, YOYO-1,...
Chlorhexidine and silver sulfadiazine coated central venous catheters (CSS-CVC) may cause loss of antimicrobial efficacy due to friction between the CVC surface sheer stress caused by blood flow. Therefore, aim this study was investigate antibacterial CSS-CVC at various flow rates using a bloodstream model.Each subjected (0.5, 1, 2, 4 L/min) wear-out times (0, 24, 48, 72, 96, 120 hours), optical density (OD) 600 after Staphylococcus aureus incubation test used determine effect CSS-CVC.In 0.5...
Objective General anaesthesia with tracheal intubation results in sore throat. We evaluated the influence of two-handed jaw thrust on postoperative throat patients who require intubation. Methods In this prospective, double-blind, single-centre, parallel-arm, and randomised trial, 92 were scheduled for general total hip arthroplasty allocated to one two groups. group (n = 46), manoeuvre was applied at control conventional sham performed. Incidences airway morbidities including throat,...
Organ transplant in humans is an established therapy for a variety of end-stage organ diseases. However, due to shortages and lack donors, the need xenotransplant has gradually increased. Xenotransplantation great potential solve many problems facing transplantation. Pigs are being developed as xenogeneic donors use humans. In this study, we propose novel simple method tracheal intubation swine model using neuromuscular blocking agents laryngeal mask airway.Eight Yorkshire pigs were used 2...

Various methods of assessing the depth anesthesia (DoA) and reducing intraoperative awareness during general have been extensively studied in anesthesiology. However, most DoA monitors do not include brain activity signal modeling. Here, we propose a new algorithm termed cortical index (CAI) based on signals. In this study, enrolled 32 patients who underwent laparoscopic cholecystectomy. Raw electroencephalography (EEG) signals were acquired at sampling rate 128 Hz using BIS-VISTA with...
