Comparison of Direct Laryngoscopy With McCoy Blade and BPL Video Laryngoscopy for Intubation in Patients Undergoing Elective Cervical Spine Surgery.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFor patients having cervical spine instability, stabilization of the neck is crucial to prevent further damage to the spinal cord, which can make laryngoscopy challenging. Specialized tools like McCoy blade direct laryngoscope (Surgitech, India) and BPL video laryngoscope (BPL Medical Technologies Pvt. Ltd., India) enhance airway management in these groups of patients. This study compared the efficacy and safety of direct laryngoscopy with McCoy blade and BPL video laryngoscopy in cervical spine surgery patients. MATERIALS AND
methodsThis randomized prospective comparative study was performed on 60 patients of ASA physical status I & II, either sex, 18 to 65 years of age, undergoing elective cervical spine surgery under general anesthesia. Patients were divided into groups B (BPL) and M (McCoy), with 30 patients in each group. After successful intubation, time for intubation, Modified Cormack Lehane grading, intubation difficulty score, ease of intubation, and hemodynamic parameters were recorded at numerous intervals.
resultsThe mean duration for tracheal intubation was longer in Group B (36.30 ± 19.75 seconds) as compared to Group M (28.07 ± 10.19 seconds), which was statistically significant. The MCL grading, in Group B, was 76.67% and in Group M 46.67% of patients achieved MCL grade 1, which was statistically significant (p = 0.049), indicating better visualization of the vocal cords in Group B. Intubation difficulty score, in Group B, was 56.67% patients, and in Group M, only 23.33% patients achieved a score of 0 and it was also statically significant (p=0.042). 86.67% of patients in Group B and 60.00% of patients in Group M had ease of intubation scores 1, which were statistically significant (p = 0.040). All hemodynamic parameters were found statically insignificant in both groups.
conclusionsThis study revealed that BPL video laryngoscopy took more time for intubation but provided better vocal cord visualization and easier intubation, while McCoy blade intubation took less time for tracheal intubation and all hemodynamic parameters remained stable in both groups.
