Safety Analysis of a New Portable Electrical Drill With a Smart Autostop Mechanism for Bedside Cranial Procedures.
Article in Operative neurosurgery (Hagerstown, Md.), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
BACKGROUND AND
objectivesBedside procedures are often helpful for neurosurgical patients, especially in neurocritical care. Portable drills with technological advancements may bring more safety and efficiency to the bedside. In this study, we compared the safety and efficiency of a new cordless electric drill with smart autostop ("HD"-Hubly Cranial Drill, Hubly Surgical) with those of a well-established standard traditional electrical neurosurgical perforator ("ST").
methodsA cadaveric study was conducted using both drills to perform several burr holes in the fronto-temporo-parietal region of the skull. An evaluation was performed on the number of dura plunges, and complete burr hole success rates were compared.
resultsA total of 174 craniotomies using the HD and 36 burr holes using the ST perforator were performed. Despite significantly exceeding intended drill bit tolerance by multiple uses of a single-use disposable HD, autostop engaged in 100% of the 174 craniotomies and before violating dura in 99.4% of the 174 craniotomies, with the single dura penetration occurring on craniotomy no. 128 after the single-use drill bit had significantly dulled beyond its single-use tolerance. Autostop engaged before dura penetration for 100% of the 36 burr holes drilled with the ST perforator ( P = .610). All the perforations were complete using the HD after resuming drilling. An autostop mechanism in a cranial drill is not commonly available for portable bedside perforators. In the operating room, most use a mechanical method to stop the rotation after losing bone resistance. This new drill uses an electrical mechanism (smart autostop) to stop drilling, making it a single-use cranial drill with advanced features for safety and efficiency at the bedside.
conclusionThere was no difference in the safety and efficacy of the new cordless electric drill with smart autostop when performing craniotomies compared with a traditional well-established electric cranial perforator with mechanical autostop on a cadaveric model.
