Purpose: To compare the safety and efficacy of the laryngeal mask airway (LMA) with the Guedel airway during the recovery period. Methods: In a prospective randomised trial in the Post Anesthesia Care Unit (PACU), 52 patients (ASA I and 2) were randomised to receive either a laryngeal mask airway (LMA: n = 26) or a Guedel airway (n = 26) during the recovery period after middle ear surgery. Ease...

BACKGROUND AND AIMS A popular method of providing anesthesia for laryngeal mask airway (LMA) insertion is with the use of propofol. However, bolus propofol has been associated with adverse effects such as hypotension, apnea and pain on injection. Hence, time is needed to search an alternative. We aimed to compare the induction characteristics, ease of LMA insertion, hemodynamic changes and comp...

OBJECTIVE To assess flexible laryngeal mask airway (F-LMA) use during pediatric adenoidectomies in terms of patient safety, comfort, complication rates and surgeon satisfaction levels. METHODS Patients who had undergone an elective adenoidectomy after receiving general anesthesia using F-LMA from June 2012 to November 2015 were included. Patients' demographics and the incidence of perioperati...

UNLABELLED We tested the hypothesis that pressure-support ventilation (PSV) allows a reduction in emergence time and laryngeal mask airway (LMA) removal time after general anesthesia compared to volume-controlled mechanical ventilation (CMV). Because spontaneous breathing (SB) is often used with LMA under general anesthesia, patients were allocated randomly to three groups (CMV, SB and PSV). Th...

The self-assembly of the protein shell ("capsid") of a virus appears to obey the law of mass action (LMA) despite the fact that viral assembly is a nonequilibrium process. In this paper we examine a model for capsid assembly, the "assembly line model," that can be analyzed analytically. We show that, in this model, efficient viral assembly from a supersaturated solution is characterized by a sh...

Background: A new supraglottic device, the LMA-SupremeTM, has recently become available for clinical use. Information on anaesthetic and co-adjuvant requirements for insertion of the LMA-SupremeTM is limited. The present study aimed to evaluate the optimal effect-site concentration of propofol in 50 % (EC50) of adults necessary for successful insertion of the LMA-SupremeTM and to examine remife...

BACKGROUND: Laryngeal Mask Airway (LMA) fills a niche between the facemask and endotracheal tube. For LMA insertion, use of only propofol as sole induction agent has less success rate. So many co-induction agents had been tried to get better success rate. Aim: To evaluate whether midazolam or mini-dose succinylcholine eases LMA insertion during propofol anaesthesia. MATERIALS AND METHOD: 75 adu...

We investigated the time course of neural processing of multi-digit additions in high- (HMA) and low-math anxious (LMA) individuals. Seventeen HMA and 17 LMA individuals were presented with two-digit additions and were asked to perform a verification task. Behavioral data showed that HMA individuals were slower and more error prone than their LMA peers, and that incorrect solutions were solved ...
