Randomized Controlled Trial Comparative StudyA randomized trial comparing sevoflurane and propofol in children undergoing MRI scans.
We compared three primary outcomes of pausing the magnetic resonance imaging (MRI) scan, emergence quality and respiratory complications. ⋯ Our study compared the three primary outcomes of pausing, agitation, and respiratory complications between the two groups, and we found no difference in respiratory complications. However, the GAP group had more pausing and less agitation than the GAS group.

ReviewPediatric transtracheal and cricothyrotomy airway devices for emergency use: which are appropriate for infants and children?
Cricothyrotomy or insertion of a transtracheal device is a life-saving maneuver that may be performed on an emergent or semi-elective basis as a means of bypassing an obstructed upper airway. A surgeon is trained to perform this life-saving procedure whereas most anesthesiologists are not facile with the scalpel. It is for this reason that many percutaneous devices have been developed for use by surgeons and nonsurgeons alike. ⋯ This paper will review many (but not all) of the available devices, associated literature, pitfalls and dangers. It is emphasized that each clinician should become familiar with the advantages and disadvantages of these devices and obtain training with simulators or animal models. A strategy for management of the 'cannot ventilate, cannot oxygenate, cannot intubate' situation should be developed with age and size appropriate equipment.

Review Historical ArticlePediatric laryngoscopes and intubation aids old and new.
This review summarizes the evolution of the pediatric laryngoscope using some of the established landmarks in the history of anesthesia. Children were rarely intubated before 1940 though the subsequent 30 years saw a proliferation of pediatric laryngoscopes in part driven by the developments in pediatric anesthesia and surgery, manufacturing techniques and materials and a change in airway management philosophy exemplified by Jackson Rees's argument against the notion that intubation was to be avoided in children. ⋯ Images from many of these devices may be enhanced by digital camera or real-time video technology. The prospect of future laryngoscope development is glimpsed in the arrival of light emitting diode light source technology and questions remain regarding the consequences of equipment disposability and at the fidelity of disposable equipment manufacture.

This article looks at the current techniques and equipment recommended for the management of the difficult intubation scenario in pediatric practice. We discuss the general considerations including preoperative preparation, the preferred anesthetic technique and the use of both rigid laryngoscopic and fiberoptic techniques for intubation. The unanticipated scenario is also discussed.

ReviewIatrogenic damage to the pediatric airway. Mechanisms and scar development.
Iatrogenic damage to the pediatric airway occurs rather often. Most injuries will heal without any sequelae because larynx and trachea of children tolerate considerable trauma. ⋯ A selection of photo documents of airway endoscopy out of more than 5000 photos from the years 1987-2007 were used to explain the development of injuries from minor lesions to large areas of necrosis of the mucosa of larynx and trachea of infants and children. The visualization of airway lesions might help to prevent iatrogenic damage.
