Effect of topical vibration on pain during scalp block injections in awake craniotomy and deep brain stimulation surgery : Analgesic effects of vibratory stimulation during scalp blocks.
Trial report in Die Anaesthesiologie, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06038825 (The Effect of Topical Vibration on Injection Pain in Scalp Block), which is not on this map. Not yet cited in PubMed.
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.

Abstract
BACKGROUND AND
aimAwake craniotomy and deep brain stimulation (DBS) procedures require the patient to be awake and adequate anesthesia conditions are typically achieved using a scalp block. These procedures inherently involve some degree of pain from local anesthetic injections during scalp block administration. We aimed to reduce the injection pain in scalp blocks using a vibration stimulus.
methodsA total of 56 patients aged between 18 and 75 years undergoing awake craniotomy and DBS procedures were enrolled in the study. All patients received a loading dose of dexmedetomidine before scalp block administration. Local anesthetic injections were applied sequentially to the identically named nerves on the right and left sides of the head. A vibration device was used during injections on one side, while injections on the other side were performed without vibration. The numeric rating scale (NRS) score and hemodynamic measurements during each injection, including heart rate and mean arterial pressure were compared between vibration and nonvibration sides.
resultsThe NRS scores were lower on the side where vibration was used during scalp block injections (P < 0.001). Additionally, there was a decrease in heart rate and mean arterial pressure on the side where vibration was used compared to the baseline value (P < 0.005).
conclusionThe study showed that using topical vibration during a scalp block can decrease the pain of a local anesthetic injection and maintain hemodynamic stability.
