About

The goal of this clinical trial is to know which type of laryngoscope is better for Double Lumen Tube (DLT) insertion, in participants undergoing elective thoracic surgeries.

The main question aim to answer is Is C-MAC blade D video laryngoscope better than Macintosh laryngoscope for DLT insertion in term of time taking for intubation and hemodynamic changes to laryngoscopy? Researchers are comparing two groups of participants

• Participants in Group A are receiving intubation from C-MAC blade D video laryngoscope.
• Participants in Group B are receiving intubations from Macintosh laryngoscope.

Full description

Double Lumen Tube (DLT) is a common airway management device, used to implement lung isolation technique during thoracic surgeries. Intubation of DLT is challenging because it is much larger in diameter and rotational insertion technique is associated with significant risk of prolong intubation, intubation failure, greater hemodynamic changes and airway trauma.

Objective of this study is to compare the outcome C-MAC blade D video laryngoscope and Macintosh laryngoscope for DLT insertion, in term of time taking for DLT intubation and hemodynamic changes to laryngoscopy.

This study is conducting at Department of Anesthesiology at SMBBIT, Pakistan. Data is collecting after taking approval from Ethical Review Committee and written informed consent from participants.

Participants are enrolling by primary investigator, day before surgery. All participants are undergoing simple randomization by lottery method.

During induction of aesthesia, time for intubation is noting from introduction of the laryngoscope blade till three complete capnograph cycles.

Participants have also been assessed for hemodynamic parameters {Heart Rate (HR), Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP) and Mean Arterial Pressure (MAP)} to intubation at 0 (Baseline), 1st Minute , 3rd Minute and 5th Minute after intubation.

After Completing data collection, Data analysis will be done by using SPSS version 26.
