Comparative evaluation of self-pressurized Air-Q and Proseal™ LMA in patients undergoing elective surgery under general anaesthesia: A randomized clinical trial.

Background And Aims: Intra-cuff pressure of Air-Q self-pressurized laryngeal airways (Air-Q SP) balances airway pressure and adapts to patient's pharyngeal and periglottic structures, thus improves oropharyngeal leak pressure (OLP).This study was performed to compare efficacy of Air-Q SP with Proseal laryngeal mask airway (PLMA) in patients undergoing elective surgery.

Material And Methods: The study design was prospective, randomized and controlled.

Awake videolaryngoscopic orotracheal intubation in patients with laryngeal tumour using the C-MAC D-Blade.

Background And Aims: This study assessed the applicability of C-MAC videolaryngoscope (VL) D-blade for awake intubation in patients with laryngeal tumour. The primary study objective was to determine the rate of successful intubation in the first attempt. The other parameters recorded were number of attempts required for intubation, duration of different stages of intubation, haemodynamics, ease of intubation and patient comfort on visual analogue scale (VAS) postoperatively.

Comparison of prophylactic phenylephrine and norepinephrine infusion on umbilical arterial pH and maternal blood pressure during spinal anaesthesia for caesarean delivery.

Background And Aims: Spinal anaesthesia induced maternal hypotension in parturients undergoing caesarean delivery may lead to neonatal acidosis and fall in umbilical artery pH. The aim of this study was to compare low dose norepinephrine infusion with phenylephrine to see the effect on umbilical arterial pH and maternal blood pressure during spinal anaesthesia for caesarean delivery.

Methods: In a randomised, double-blind study, 60 parturients belonging to American Society of Anesthesiologists grade II, age 18-35 years with singleton term pregnancy were divided into the phenylephrine group and norepinephrine group.

Comparison of different types of stylets with no-stylet technique for intubation with C-MAC D-Blade® videolaryngoscope in simulated difficult airway: A prospective randomized study.

Background: The angulated C-MAC D-Blade videolaryngoscope (VL) is designed for difficult intubation and may not be compatible with standard PVC endotracheal tubes.

Objective: Present study was planned to compare efficacy of C-MAC, D-blade VL using endotracheal tube with three different stylets versus No stylet in patients undergoing tracheal intubation with simulated difficult airway.

Methods: After obtaining written consent and IEC approval, total 144 adult patients were allocated to four groups of 36 each using no stylet or different types of stylets.

Comparative evaluation of Air-Q blocker and Proseal laryngeal mask airway in patients undergoing elective surgery under general anaesthesia: A randomised controlled trial.

Background And Aims: The Air-Q blocker (Cook gas LLC, Mercury Medical, Clearwater, FL, USA) is a relatively new supraglottic airway device (SAD) with capability to serve as a conduit for intubation. As there is limited data on Air-Q blocker, the present study was performed to compare the efficacy of Air-Q blocker and Proseal laryngeal mask airway (PLMA) in patients undergoing elective surgery.

Methods: A total of 90 American Society of Anesthesiologists (ASA) physical status I and II patients were randomly allocated to Air-Q blocker or PLMA group.

Comparison of the Supreme and the ProSeal laryngeal mask airway in patients undergoing laparoscopic cholecystectomy: A randomized controlled trial.

Objective: The single-use LMA Supreme (Teleflex, Inc., Wayne, PA, USA) and the LMA ProSeal (Teleflex, Inc., Wayne, PA, USA) laryngeal mask airway (LMA) have similar characteristics.

Intranasal clonidine vs. midazolam as premedication in children: a randomized controlled trial.

Objective: To compare anxiolysis produced by intranasal clonidine with intranasal midazolam as premedication in children undergoing surgery.

Design: Double-blind randomized controlled study.

Setting: Tertiary-care hospital, July 2009 to June 2010.

Effect of intraoperative depth of anesthesia on postoperative pain and analgesic requirement: A randomized prospective observer blinded study.

Background: Intraoperative depth of anesthesia may affect postoperative pain relief. This prospective, randomized, and observer-blinded study assessed the effect of intraoperative depth of anesthesia on the postoperative pain and analgesic requirements in patients undergoing laparoscopic cholecystectomy.

Materials And Methods: A total of 80 patients were randomly divided into two groups of 40 each.

A randomized controlled study to evaluate and compare Truview blade with Macintosh blade for laryngoscopy and intubation under general anesthesia.

Background: The Truview EVO2™ laryngoscope is a recently introduced device with a unique blade that provides a magnified laryngeal view at 42° anterior reflected view. It facilitates visualization of the glottis without alignment of oral, pharyngeal, and tracheal axes. We compared the view obtained at laryngoscopy, intubating conditions and hemodynamic parameters of Truview with Macintosh blade.
