Cardiac arrest complicating routine throat pack insertion in oral and maxillofacial surgery under general anesthesia: A case report.

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
Throat packs are routinely inserted during oral and maxillofacial surgery and are generally considered safe. However, severe vagally mediated cardiovascular reflexes can rarely occur during airway or oropharyngeal manipulation. The present study describes a rare case of cardiac arrest directly attributed to throat pack insertion. A healthy 54-year-old male patient underwent third molar extraction under general anesthesia. Immediately following throat pack placement, he developed sudden cardiac arrest with complete electrical asystole lasting ~20 sec. Spontaneous circulation returned rapidly following the intravenous administration of ephedrine (8 mg) without the need for chest compressions. This event was most consistent with a vagal reflex-mediated response. The present case report indicates that vigilant hemodynamic monitoring, adequate ventilation and appropriate anesthetic depth are essential even during routine adjunctive steps, such as throat pack insertion.
