Comparative Study Clinical Trial Controlled Clinical Trial
Comparison of phonomyography with balloon pressure mechanomyography to measure contractile force at the corrugator supercilii muscle.
Phonomyography is based on the creation of low frequency sounds during muscle contraction, which can be recorded and used for neuromuscular monitoring. In this study, balloon pressure mechanomyography, a novel method to measure the force of contraction via pressure changes in an air-filled balloon, was compared with phonomyography to determine neuromuscular blockade at the corrugator supercilii muscle. ⋯ We applied a balloon pressure method to measure the force at the corrugator supercilii. Phonomyography at the corrugator supercilii shows good agreement with this modified version of mechanomyography.

Randomized Controlled Trial Comparative Study Clinical Trial
The McCoy straight blade does not improve laryngoscopy and intubation in normal infants.
The McCoy curved blade laryngoscope has been demonstrated to improve view at laryngoscopy in adults. A straight-bladed version of this laryngoscope has recently been introduced into pediatric practice. The objective of this prospective, randomized study was to compare the intubating conditions afforded by the McCoy (#1) straight blade laryngoscope with the conventional Miller (#1) blade in neonates and infants. ⋯ Our data indicate that the McCoy blade has no advantage over the conventional pediatric Miller blade in normal infants.

The responsibility of acute airway management often falls into the hands of non-anesthesiologists. Emergency physicians now routinely use neuromuscular blockade to facilitate intubation. The literature in support of this practice has almost exclusively been published in emergency medicine (EM) journals. This body of literature is presented and issues of educational support are discussed. ⋯ The role of non-anesthesiologists in acute airway management is significant. Despite shortcomings in methodology, current evidence and practice supports the use of RSI by trained emergency physicians. Constructive collaborative efforts between anesthesiology and EM need to occur to ensure that educational needs are met and that competent airway management is provided.

Randomized Controlled Trial Comparative Study Clinical Trial
[Remifentanil is an effective alternative to propofol for patient-controlled analgesia during digestive endoscopic procedures].
Unlike propofol, the self-administration of remifentanil for sedation in gastrointestinal endoscopies has never been evaluated formally. We wanted to compare the efficacy and tolerance of patient self-administration of remifentanil vs propofol during gastrointestinal endoscopy. ⋯ The self-administration of remifentanil for sedation during gastrointestinal endoscopies is as effective as the self-administration of propofol and can be offered to patients, especially when it is desirable that they remain conscious during the procedure.
