-Summary

The aim of this study is to answer the question of whether direct laryngoscopy can be performed with videolaryngoscopes. How do the videos of the laryngoscopes provide images directly in laryngoscopy? Primary objective: To compare the images of Hugemed and Mcgrath videolarinygoscope in direct laryngoscopy and indirect laryngoscopy secondary objective: to compare the effects on haemodynamic response Participants :people who are not expected to have difficult intubation

+Arms and interventions

Arm	Type	Interventions	Description
Group MC McGrath videolaryngoscope Group H Hugmed Videolaryngoscope		Other: endotracheal intubation with videolaryngoscope	All patients will receive intravenous premedication with midazolam 0.03 mg/kg approximately 30 minutes before induction of anaesthesia. Preoperatively, standard monitoring included a 3-lead electrocardiogram (ECG) with continuous ST-segment analysis and assessment of peripheral oxygen saturation (SpO2) and intermittent non-invasive blood pressure. Following preoxygenation with 100% oxygen for three minutes, general anaesthesia would be induced with propofol (3mg/kg) a few minutes after injection of fentanyl (2µg/kg). Neuromuscular paralysis will be induced with rocuronium (0.5 mg/kg) in all patients.In group MC, direct and indirect Modified Cormack Lehane score and POGO score will be evaluated with McGrath videolaryngoscope. In Group H, direct and indirect Modified Cormack Lehane score and POGO score will be evaluated with Hugemed videolaryngoscope.

endotracheal intubation with videolaryngoscope (Other): The present study will compare the images of two different VLs with Macintosh blades (the McGrath videolaryngoscope and the Hugemed videolaryngoscope) in both indirect (screen images) and direct (images viewed through the mouth) laryngoscopy.

+Outcome measures

Primary outcomes

Comparison of Direct and Indirect Images of Two Different Video Laryngoscopes in Adult Airway Management [3 months]: Videolaryngoscopy (VL) is a frequently used method in airway management to improve the success of tracheal intubation in recent years. VLs have a miniature video camera at the tip of the blades which allows indirect visualisation of the glottis (1,2,3). The American Society of Anaesthesiologists (ASA) recommends that a VL should be available and used for all patients with a particularly difficult airway and for whom intubation is planned In recent years, a number of VLs have emerged that offer several advantages over direct laryngoscopy.It is aimed to compare direct and indirect images of mcgrath and hugemed videolaryngoscope.
Comparison of Direct and Indirect Images of Two Different Video Laryngoscopes in Adult Airway Management [3 months]: The principal objective of this study was to undertake a comparative analysis of the images produced by two distinct VLs during direct and indirect laryngoscopy
