“…The LTS is a further development of the LT, which allows the separation of respiratory and alimentary tract. Many studies have reported successful ventilation using the LT or LTS (2–7). Lately, LTS was remodeled into LTS II with following characteristics: a longer shaft, a more pointed tip, and a redesigned distal balloon to better fit esophageal inlet.…”

“…These articles suggest that the success of the Laryngeal Tube Ò on first insertion attempt, sore throat, dysphonia, and rate of gastric insufflation is similar to that of the LMA TM , while leak pressure is higher and the fibreoptic laryngeal view is not as good. 18,19 Most of this information applies to children older than 2 years and/or [10 kg. In smaller children, there are limited data, and the data that exist suggest a high failure rate in children \10 kg.…”

The first prototype of the laryngeal mask airway (LMA TM ) was used clinically in the summer of 1981 at Ashford, Kent, UK, by Dr. Archie Brain. Dr. Brain followed in the worthy footsteps of Clover, O'Dwyer, Shipway, Leech, and others in developing a supraglottic airway to facilitate the delivery of anesthetic gases via a reliable supraglottic airway. 1 The LMA TM was released in the UK in 1988 and in the USA in 1992. Since the original range of pediatric LMAs TM was soon found to be inadequate to address all children's sizes, half-sizes (1.5 and 2.5) were developed. As with adult practice, the LMA TM and other supraglottic airways have radically changed pediatric anesthesia practice and have become a key component of airway management in children, both in the operating room and in remote anesthesia locations. These devices have increasingly been advocated for emergency airway control in the field, in the emergency department, and in the delivery suite. So what have we learned about pediatric supraglottic airways over the past two decades and where does the future lie with respect to these devices?Much of the published research in this area relates to the LMA Classic TM . From the clinical anesthesiologist's perspective, the following questions relating to the LMA Classic TM are important: When should it be used (patient and procedure related factors), how should it be used, and when should an alternative device be used?Indications for the use of the LMA Classic TM are extensive, and it is often the airway of choice in routine general anesthesia for minor procedures in children. In a prospective study of 1,400 children who had LMA TM -based anesthesia conducted by supervised trainees, the device was found to be highly effective for a broad range of surgical procedures, and there was no instance where the LMA TM had to be replaced with an endotracheal tube (ETT). 2 Initial misgivings about the use of the LMA TM for head and neck procedures were shown to be largely unfounded. For example, the LMA TM was shown to be safe and effective when used for ophthalmological surgery and adenotonsillectomy in children 3,4 ; however, these situations require a surgeon with some insight that the trachea is not intubated.Pediatric anesthesia is increasingly being delivered in areas outside the operating room where the LMA TM has been proven to be particularly valuable. For instance, the LMA TM has been used for radiotherapy, 5 magnetic resonance imaging, 6 fibreoptic bronchoscopy, 7 and upper gastrointestinal endoscopy. 8 Its relative stability combined with the ease of respiratory monitoring and the relative lack of airway complications are distinct advantages in these remote locations.One clinical scenario of particular interest is the difficult pediatric airway. Here the LMA TM has proven to be invaluable both as a rescue airway device in the child with a difficult airway and as a conduit for fibreoptic bronchoscopy and endotracheal intubation. 7 Consequently, the LMA TM has a role in both anticipated and unanticipated difficu...

“…Eine ähnliche Untersuchung wurde von Genzwürker et al ( [14], LoE: 2b) an einem größeren Patientenkollektiv von 60 Kindern durchgeführt. Dabei wurden Kinder im Alter von 2 bis 8 Jahren mit normalem Atemweg im Rahmen von elektiven Allgemeinnarkosen untersucht.…”

“…Gleichzeitig war die Inzidenz von Halsschmerzen trotz Beachtung eines maximalen Cuff-Drucks von 60 cm H 2 O höher. Insgesamt wird die Anwendung des LT gegenüber der LM von den Autoren dieser Studie favorisiert [14]. Eine wichtige Limitation stellt jedoch das Alter der eingeschlossen Patienten (ab 2 Jahre) dar, sodass keine Aussage zur Anwendbarkeit des LT bei Kindern unter 2 Jahren möglich ist.…”

Considering the scientific data and the large clinical experience with the LM in medical routine and emergency situations in children, currently only the LM can be recommended for alternative (i.e. non-intubation) airway management in children. If alternative airway management is part of a local emergency strategy, the LM should be provided in all pediatric sizes (1, 1.5, 2, 2.5, 3, 4 and 5) for prehospital and in-hospital emergency use and all users should be regularly trained in its application.

Prospective, randomized comparison of laryngeal tube and laryngeal mask airway in pediatric patients

Abstract: Insertion success rate is high with both LMA and LT in the age group studied. The airway leak pressure, serving as an estimate to judge quality of airway seal, is higher with the LT.
