“…[14][15][16][17]. Again, these discrepancies may be due to the fact that different airway management trainers were used and the fact that the 'anatomy' of the trainers is better or less suited for a specific airway device.…”

) and tracheal intubation (TI) were compared in a manikin study. Nurses, anaesthetic nurses, paramedics, physicians and anaesthetists inserted the devices three times in a randomised sequence. Time taken for successful insertion, success rates and ease of insertion were evaluated. Anaesthetists performed tracheal intubation significantly faster than other healthcare professionals (p < 0.05). Insertion times for the cLMA, PLMA, LT and CT were not significantly different between the groups. Insertion of the CT, ILMA and TI was associated with a significant learning effect in all groups. This was not observed with the cLMA, PLMA or LT. All non-anaesthetists were able to insert the cLMA, PLMA and LT within two attempts with a > 90% success rate on the first attempt. The ILMA and TI were the only devices where more than one subject experienced some difficulty in insertion. The cLMA, PLMA and LT should be evaluated for use in situations where only limited airway training is possible.

“…The left internal thoracic vein accompanies the left internal thoracic artery, passes a finger's breath from the border of the sternum and is situated closer to the sternal end of the clavicle compared with the left superior intercostal vein. The chest X-ray usually shows the catheter passing through or to the left of the aortic knuckle [1]. Although our patient came to no harm there was a danger of vessel rupture, incorrect CVP pressure readings and failure to deliver essential fluids and drugs.…”

“…The catheter has been reported to be found in the right or left internal thoracic vein [1], the left superior intercostal vein [2] and in a partial anomalous pulmonary venous channel [3]. The left superior intercostal vein drains blood from the left second and third intercostal veins, runs over the arch of aorta and empties into the left brachiocephalic vein.…”

“…Although our patient came to no harm there was a danger of vessel rupture, incorrect CVP pressure readings and failure to deliver essential fluids and drugs. The laryngeal tube (VBM, Medizintechnik, Germany) [1,2] has a potential role in providing a clear airway during cardiopulmonary resuscitation, although it may share limitations with the laryngeal mask airway in patients with an increased risk of pulmonary aspiration. Its use during cardiopulmonary resuscitation has been reported in a number of patients [3,4].…”

P Pu ur rp po os se e: : The laryngeal tube airway (LTA) is a new extraglottic airway device with a large proximal cuff that inflates in the laryngopharynx and a distal conical cuff that inflates in the hypopharynx. We determine the influence of the cuff volume and anatomic location on pharyngeal mucosal pressures for the LTA.M Me et th ho od ds s: : Fifteen fresh cadavers were studied. Microchip sensors were attached to the (anatomic location) anterior, lateral and posterior surface of the distal cuff (hypopharynx) and proximal cuff (laryngopharynx) of the size 4 LTA. Oropharyngeal leak pressure (OLP) and mucosal pressures were measured at 0-140 mL cuff volume in 20-mL increments. In addition, mucosal pressures for the proximal cuff were measured in three awake, topicalized volunteers.R Re es su ul lt ts s: : OLP and mucosal pressure at all locations increased with cuff volume (all: P < 0.01). Mucosal pressures were highest posteriorly. Mucosal pressures only exceeded 35 cm H 2 O (pharyngeal mucosal perfusion pressure) in the anterior and posterior laryngopharynx and when the cuff volume was > 80-100 mL. Mucosal pressures were similar for cadavers and awake volunteers.C Co on nc cl lu us si io on n: : Mucosal pressures for the LTA increase with cuff volume, are highest posteriorly and potentially exceed mucosal perfusion pressure when cuff volume exceeds 80-100 mL. HE laryngeal tube airway (LTA; VBM Medizintechnik GmbH, Sulz, Germany), first described by Agro et al. 1 in 1999, is a new extraglottic airway device for resuscitation and anesthesia. It consists of an airway tube with a large proximal cuff that inflates in the proximal pharynx to form an airtight seal and a distal conical cuff that inflates in the hypopharynx to prevent regurgitation and gastric insufflation. A single pilot balloon and inflation tubing inflate both cuffs. Early clinical studies suggest that there is a high insertion success rate, 2 positive pressure ventilation is fair to excellent in 88% 1084 CARDIOTHORACIC ANESTHESIA, RESPIRATION AND AIRWAY Objectif : Le tube d'intubation laryngé (TIL) est un nouvel appareil d'intubation extraglottique muni d'un grand ballonnet proximal qui
