Randomized Controlled Trial Comparative StudyComparison of auditory evoked potential index and clinical signs as indicator for laryngeal mask airway insertion.
Auditory evoked potential (AEP) index is one of the several physiological parameters for assessing the depth of anesthesia. The purpose of this study was to investigate whether the AEP monitoring could provide a better information for assessment of anesthesia level in classic laryngeal mask airway (C-LMA) insertion than the use of clinical signs in general anesthesia with single standard dose of intravenous propofol and fentanyl. ⋯ This study demonstrated that AEP index provided better information for C-LMA insertion with higher successful rate, less emergence of airway reflex and lower incidence of movement during induction of general anesthesia with single dose of intravenous propofol and fentanyl.

Most of the potent analgesics currently in use act through the mu opioid receptor. Although they are classified as mu opioids, clinical experience suggests differences among them. The relative potencies of the agents can vary from patient to patient, as well as the side-effect profiles. ⋯ The explosion in molecular biology has led to the identification of a single gene encoding mu opioid receptors. It now appears that this gene undergoes extensive splicing, in which a single gene can generate multiple proteins. Evidence now suggests that these splice variants may help explain the clinical variability in responses among patients.

Forces applied to the maxillary incisors during tracheal intubation and dental injury risks of intubation by beginners: a manikin study.
We wished to determine whether dental injuries during intubation would occur more frequently when performed by inexperienced beginners. We measured the laryngoscopic force exerted on maxillary teeth of a modified manikin by experienced anesthesiologists and unexperienced medical students and estimated the injury risk. ⋯ Our results suggest that the experience levels of the laryngoscopists are not a major determinant of dental injuries in patients with healthy dentition.

Randomized Controlled Trial Comparative StudyComparison of the performance of 'Intubating LMA' and 'Cobra PLA' as an aid to blind endotracheal tube insertion in patients scheduled for elective surgery under general anesthesia.
Supraglottic airways (SGA) through which blind endotracheal intubation is made possible is an area of considerable interest. Our study aimed at comparing the Cobra Perilaryngeal Airway (CPLA) with the Intubating Laryngeal Mask Airway (ILMA) with regard to the performance of the former as a conduit for facilitating blind endotracheal intubation. ⋯ We conclude that CPLA can be used as an effective conduit for blind endotracheal intubation with cuffed PVC tube and has comparable efficacy in tracheal intubation as that with ILMA.
