Adverse events following surgical operations are common complications due to removal of tracheal tube in contrast to the tracheal intubation. Awareness about the new methods and strategies for tracheal tube extubation is necessary for a safe and successful extubation. Therefore, we aimed to assess the safety and efficacy of laryngeal mask airway (LMA), streamlined liner of the pharyngeal airway (SLIPA) and I-gel in extubation time of tracheal tube. A one-single randomized clinical trial was conducted in 105 eligible patients in three groups including LMA, SLIPA and I-gel...

Background and Aims: Head and neck movements alter the shape of the pharynx, resulting in changes in the oropharyngeal leaking pressures and ventilation with supragottic airway devices. We compared the effect of the different head-and-neck positions on the oropharyngeal leak pressures and ventilation with the I-Gel™ and ProSeal™ laryngeal mask airway (PLMA) in anaesthetised paralysed children. Methods: A total of 70 children were randomly assigned to receive PLMA ( n = 35) or I-Gel™ ( n = 35) for airway management...

BACKGROUND: Tumor microenvironment consists of the extracellular matrix (ECM), stromal cells, such as fibroblasts-FBs and cancer associated fibroblasts-CAFs, and a myriad of soluble factors. In many tumor types, including pancreatic tumors, the interplay between stromal cells and the other tumor microenvironment components leads to desmoplasia, a cancer-specific type of fibrosis that hinders treatment. Transforming growth factor beta (TGF-β) and CAFs are thought to play a crucial role in this tumor desmoplastic reaction, although the involved mechanisms are unknown...

BACKGROUND: Transwell-based models of the blood-brain barrier (BBB) incorporating monolayers of human brain microvascular endothelial cells (dhBMECs) derived from induced pluripotent stem cells show many of the key features of the BBB, including expression of transporters and efflux pumps, expression of tight junction proteins, and physiological values of transendothelial electrical resistance. The fabrication of 3D BBB models using dhBMECs has so far been unsuccessful due to the poor adhesion and survival of these cells on matrix materials commonly used in tissue engineering...

Efforts for tissue engineering vascular grafts focuses on the tunica media and intima, although the tunica adventitia serves as the primary structural support for blood vessels. In surgery, during endarterectomies, surgeons can strip the vessel, leaving the adventitia as the main strength layer to close the vessel. Here, we adapted our recently developed technique of forming vascular tissue rings then stacking the rings into a tubular structure, to accommodate human fibroblasts to create adventitia vessels in 8 days...

OBJECTIVE: The supraglottic airway device (SAD) can be used for airway management of spontaneous breathing patients, and propofol is commonly applied for the SAD placement. This study was designed to assess the effect of gender on median target effect-site concentration (Ce 50 ) of propofol for I-gel placement when combined with dexmedetomidine. MATERIAL AND METHOD: 19 males and 18 females, aged 18 to 59 and undergoing elective surgery, were enrolled. After intravenous infusion of dexmedetomidine 1...

Background: The i-gel™ (i-gel) and Laryngeal Mask Airway Supreme™ (LMA Supreme) have been safely used in children. We compared the airway performance of the i-gel and LMA Supreme in infants undergoing general anesthesia. Methods: Sixty infants with American Society of Anesthesiologists physical status I or II were randomly assigned to place either the i-gel or the LMA Supreme. The size 1 or 1.5 of each airway was selected by the weight of infants. The primary outcome variable was oropharyngeal leak pressure (OLP)...

Background: Propofol is used for supraglottic airway device insertion, often with the i-gel. However, the propofol requirement for i-gel insertion has not been explored in paralyzed patients. This study was performed to explore hemodynamic changes and sedation level with different propofol doses in healthy paralyzed patients when the i-gel was inserted. Methods: A total of 141 patients undergoing a urologic operation were randomly allocated to three groups depending on the propofol dose (1...

The i-gel has a thick airway tube and occasionally, achieving the airway can be difficult because of obstruction in the prone position. The authors aimed at solving this problem and used a modified i-gel airway in the prone position for radiotherapy processes in children.

Thermosensitive hydrogels have been studied for potential application as promising alternative cell carriers in cell-based regenerative therapies. In this study, a thermosensitive butane diisocyanate (BDI)-collagen hydrogel (BC hydrogel) was designed as injectable cell delivery carrier of tendon stem/progenitor cells (TSPCs) for tendon tissue engineering. We functionalized the BDI hydrogel with the addition of 20% (v/v) collagen I gel to obtain the thermosensitive BC hydrogel, which was then seeded with TSPCs derived from human Achilles tendons...

OBJECTIVE To compare 6 airway-management devices in 3 isolation scenarios regarding their effect on airway management: portable isolation unit (PIU), personal protective equipment (PPE), and standard protection measures METHODS In total, 30 anesthesiologists working in emergency medical services performed airway management on mannequins in 3 isolation settings using 6 different airway management devices (in random order): (1) standard Macintosh laryngoscope; (2) Airtraq SP-video-laryngoscope; (3) i-gel; (4) LMA-Fastrach; (5) Ambu fiberoptic-aScope; and (6) Melker cricothyrotomy-set...

Background and Aims: Supraglottic airways (SGAs) are generally used for airway management; but can also be used as a conduit for tracheal intubation. Our primary aim was to evaluate i-Gel and laryngeal mask airway (LMA) classic as conduits for tracheal intubation using ventilating bougie by assessing number of attempts and time for insertion of SGAs, ventilating bougie and endotracheal tube (ETT), and total intubation time. Material and Methods: A randomized clinical trial was carried out in 58 patients requiring general anesthesia and endotracheal intubation for planned surgery...

BACKGROUND: When working in a tactical environment there are several different airway management options that exist. One published manuscript suggests that when compared to endotracheal intubation, the King LT laryngotracheal airway (KA) device minimizes time to successful tube placement and minimizes exposure in a tactical environment. However, comparison of two different blind insertion supraglottic airway devices in a tactical environment has not been performed. This study compared the I-Gel airway (IGA) to the KA in a simulated tactical environment, to determine if one device is superior in minimizing exposure and minimizing time to successful tube placement...

BACKGROUND: The optimal methodology for sedation and anesthesia during atrial fibrillation (AF) ablation has not been well established. We assessed the feasibility of total intravenous anesthesia (TIVA) by cardiologists with support from anesthesiologists during AF ablation and quality of pulmonary vein isolation (PVI) and single procedure success rate at 12 months. METHODS: TIVA was performed by cardiologists using IV propofol and fentanyl under controlled ventilation via i-gel™ without neuromuscular blocking drugs in 160 consecutive patients (80 nonparoxysmal) with no anticipated difficult airway or other severe diseases...

Current therapeutic strategies to reduce scarring in full thickness skin defect offer limited success due to poor understanding of scar tissue formation and the underlying signaling pathways. There is an urgent need to develop human cell based in vitro scar tissue models as animal testing is associated with ethical and logistic complications and inter-species variations. Pro-inflammatory cytokines play critical role in regulating scar development through complex interplay and interaction with the ECM and corresponding signaling pathways...

Background and Aims: The ProSeal™ laryngeal mask airway (PLMA), i-gel™ and Laryngeal Tube Suction-D (LTS-D™) have previously been evaluated alone or in pair-wise comparisons but differing study designs make it difficult to compare the results. The aim of this study was to compare the clinical performance of these three devices in terms of efficacy and safety in patients receiving mechanical ventilation during elective surgical procedures. Methods: This prospective, randomised, double-blind study was conducted on 150 American Society of Anesthesiologists physical status I-II patients, randomly allocated into 3 groups, undergoing elective surgical procedures under general anaesthesia...
