In this prospective randomized study, success rate of blind tracheal intubation through two different supraglottic airway devices viz. i-gel ® and the intubating laryngeal mask airway (ILMA)® was compared a using conventional polyvinylchloride endotracheal tubes. Eighty patients undergoing elective surgery under general anaesthesia were randomized in two groups comprising of 40 patients each to...

IN SURGICAL PROCEDURES necessitating one-sided thoracotomy in the lateral position it is becoming evident that, despite the use of end,tracheal and double lumen tubes, the amount of alveolar arterial (a-A) oxygen difference is very high and the Pao~ of many patients may become dangerously low?,-" Investigations were carried out on a practical level to try to find the cause for this and to devis...

Tracheostomy tubes are used to administer positive-pressure ventilation, to provide a patent airway, to provide protection from aspiration, and to provide access to the lower respiratory tract for airway clearance. They are available in a variety of sizes and styles, from several manufacturers. The dimensions of tracheostomy tubes are given by their inner diameter, outer diameter, length, and c...

A broad comparative study of insect respiratory morphology is presented. Tracheae, epidermal invaginations extending into the body in branching networks tubes, supply tissues with direct access to air for gas exchange. While previous tracheal studies focused on a handful taxa and lacked consistency, here unified system nomenclature established using visualizations from micro-CT scanning represe...

Sir,—I read with interest the article entitled "Trachea! rupture after tracheal intubation" by Regragui, Fagan and Natrajan [1]. The authors described the anaesthetic management of a patient with a distal tracheal tear. The trachea was intubated initially with an 8-mm tracheal rube under bronchoscopic guidance with the distal end of the tube above the tracheal tear. After right rhoracotomy was ...

INTRODUCTION Tip cells are specialized endothelial cells that lead the migration of sprouting vessels and mediate anastomosis formation during vascular development in vertebrates (Geudens and Gerhardt, 2011; Herwig et al., 2011). Signaling through Vascular endothelial growth factor receptor (VEGFR), a receptor tyrosine kinase (RTK), is involved in selecting tip cells and in guiding their direct...

BACKGROUND Cuff pressure (P cuff) control is mandatory to avoid leakage of oral secretions passing the tracheal tube and tracheal ischemia. The aim of the present trial was to determine the efficacy of a mechanical device (PressureEasy®) in the continuous control of P cuff in patients intubated with polyvinyl chloride (PVC)-cuffed tracheal tubes, compared with routine care using a manometer. ...

Precise control of epithelial tube size is critical for organ function, yet the molecular mechanisms remain poorly understood. Here, we examine the roles of cell growth and a highly conserved organ growth regulatory pathway in controlling the dimensions of the Drosophila tracheal (airway) system, a well-characterized system for investigating epithelial tube morphogenesis. We find that tracheal ...

OBJECTIVE In patients intubated with endotracheal tubes (ETTs), suctioning is routinely performed to remove mucus from within the ETT and trachea. The Mucus Slurper is a novel ETT with built-in suction ports arranged radially at its tip. We evaluated the safety and efficacy of the Mucus Slurper, compared with conventional tracheal suction, to prevent airway obstruction in sheep with the ETT and...

Introduction: Postoperative sore throat is a common complaint in patients with endotracheal intubation and has potentially dangerous complications. This randomized controlled trial study investigated the incidence of postoperative sore throat after general anesthesia when betamethasone gel is applied to a tracheal tube compared with when IV dexamethasone is prescribed.   Materials and Methods: ...
