Supraglottic airway devices in neuroanesthesia practice: A narrative review.
Review in Journal of anaesthesiology, clinical pharmacology. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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
Supraglottic airway devices (SADs) have a great application as an alternative to tracheal intubation, prompting a paradigm shift in routine anesthetic practice. However, its usage in neuroanesthesia is limited and debatable, considering the clinical challenges and complexity of neurosurgical procedures. Even though literature evidence exits regarding successful airway management with SADs in neurosurgery, there is no clear-cut evidence or consensus among anesthesiologists. Articles were searched in PubMed and Google Scholar by using the keywords "Supraglottic airway" AND "Laryngeal Mask" OR "LMA" AND "Craniotomy" over the past 30 years. In addition, a manual search was performed (with additional keywords "neurosurgery," spine surgery," "I-gel," "ILMA," "awake craniotomy," "radiology," "electroconvulsive therapy," and "magnetic resonance imaging") to retrieve additional articles. The primary goal of this narrative review is to determine the applicability of SADs in various neurosurgical settings. According to the review, SADs play an important role as a rescue device during intraoperative emergencies such as accidental tracheal extubation (supine, lateral, and prone positions with head fixed on cranial pins), sudden airway loss due to seizure during awake craniotomy, postoperative airway loss following trans-nasal pituitary surgeries, and macroglossia. SADs can be used successfully for short-duration minimally invasive elective procedures such as cranioplasty, burr hole evacuation of subdural collection, battery implantation for deep brain stimulation, vario-guided biopsies, and minimally invasive spine surgeries. Furthermore, SADs serve a significant function in blunting extubation responses, thereby preventing cerebral edema and tumor bed hemorrhage. Only a few studies have supported the use of SADs in long-duration major intracranial tumour surgeries, making its use controversial in major surgeries where intracranial pressure control is the key. The SADs also have clinical utility in various non-operating room neuroanesthesia procedures.
