Propofol concentration requirement for laryngeal mask airway insertion was highest with the ProSeal, next highest with the Fastrach, and lowest with the Classic type, with target-controlled infusion

Low dose of fentanyl reduces predicted effect-site concentration of propofol for flexible laryngeal mask airway insertion

“…In our study, the induction and maintenance of propofol anesthesia were performed with a TCI system using the Diprifusor. This experimental condition was similar to that in previous studies [2][3][4]. However, our study was different from these previous studies in two aspects.…”

“…The EC 95 value should be applicable to the clinical situation. However the EC 95 cannot be obtained by Dixon's up-and-down method (stair-cast method) [11], which was used in the previous studies [2,4], because this method is basically designed to detect the 50% effect dose with fewer samples. On the other hand, probit analysis also has some problems.…”

“…In a previous report, the predicted propofol effect-site concentrations (ECs) required to prevent movement of the body or limbs in 50% of patients (EC 50 ) at the insertion of various types of LMA were determined and compared with each other [2]. The results of that report showed there were signifi cant differences among propofol EC 50s for Proseal (LMA, San Diego, CA, USA), Fastrach (LMA, San Diego, CA, USA), and CLMA insertion.…”

Assessment of effect of various concentration of ketamine-propofol (ketofol) on haemodynamic parameters and LMA insertion conditions

“…3 Propofol is sedative hypnotic agent with a short onset duration and recovery time. 4 This property makes propofol an ideal agent for anesthesia but can cause cardio respiratory instability and depression at the doses needed for laryngeal mask insertion. 5,6,7 The ketamine stimulate sympathetic nervous system and increases blood pressure along with increasing the heart rate.…”

End-tidal concentrations of sevoflurane and desflurane for ProSeal laryngeal mask airway removal in anaesthetised adults

“…Hence, the anaesthetic agent requirement for PLMA removal may not corroborate with CLMA due to these structural alterations in PLMA. 2,3 The appropriate time for removal of a laryngeal mask airway (LMA) in adults is controversial. Removal during the awake state is reported with a higher incidence of complications such as coughing, biting, retching, gastric regurgitation and airway obstruction 4 as well as an increased incidence of airway hyperreactivity and damage to the LMA.…”
