Effects of different fresh gas flows and different anesthetics on airway temperature and humidity in surgical patients: a prospective observational study.

This study was aimed to investigate the effects of different fresh gas (oxygen + air) flow rates and different anesthetics on airway temperature and humidity when using the same anesthesia machine in patients undergoing general anesthesia. In this prospective, observational study, 240 patients with American Society of Anesthesiologists (ASA) I-II between the age of 18-65 years to be operated under general anesthesia were enrolled and divided into two groups according to the fresh gas flow rate (3-6 L/min). Each of the two main groups was further divided into three subgroups according to the administered anesthetic gases and drugs.

Comparison of the intubation success rate between the intubating catheter and videolaryngoscope in difficult airways: a prospective randomized trial.

Background: Several devices and algorithms have already been examined and compared for difficult airway management. However, there is no existing study comparing the success of the Intubating Catheter (IC) and the Videolaryngoscope (VL) in patients who are difficult to intubate. We aimed to compare Frova IC and McGrath VL in terms of intubation success rates in patients with difficult intubation.

A comparative randomized trial of intubation success in difficult intubation cases: the use of a Frova intubation catheter versus a Bonfils intubation fiberoscope.

Introduction: A difficult airway is one of the main causes of morbidity and mortality in patients who undergo surgical interventions. Therefore, many devices and algorithms have been developed for the management of a difficult airway. However no study has been conducted comparing Frova catheter (FC) and a Bonfils fiberoscope (BF) to date.
