Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients classified as Mallampati 1 or 2 and ASA 1 or 2, scheduled for elective thoracic surgeries under general anesthesia.

Probably not a fit

Patients with anticipated difficult airways, significant obesity, or other complications may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to determine which laryngoscope, the C-MAC blade D video laryngoscope or the Macintosh laryngoscope, is more effective for double lumen tube (DLT) insertion in patients undergoing elective thoracic surgeries. Participants will be randomly assigned to one of two groups, with intubation times and hemodynamic changes monitored during the procedure. The study will assess the time taken for intubation and changes in heart rate and blood pressure at various intervals post-intubation. Data will be analyzed using SPSS to evaluate the outcomes of each laryngoscope type.

Why it matters

Potential benefit: If successful, this study could improve intubation efficiency and patient safety during thoracic surgeries.

How similar studies have gone: While there have been studies comparing different laryngoscopes, this specific comparison of the C-MAC blade D video laryngoscope and the Macintosh laryngoscope for DLT insertion is relatively novel.
