Accidental intrathecal injection of high-dose magnesium sulphate with conventional-dose bupivacaine: a case report.
Article in AME case reports, 2026. 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
Background: Although inadvertent intrathecal injection of medications is rare, it often leads to catastrophic neurological complications. This report describes a case of accidental intrathecal injection of high-dose magnesium sulphate combined with a local anaesthetic during anaesthesia for orthopaedic surgery, aiming to raise clinical awareness of safety regarding drug administration routes. Case Description: An 80-year-old female patient underwent emergency spinal anaesthesia for surgical repair of a left femoral neck fracture. Due to the inadvertent addition of magnesium sulphate to bupivacaine for intrathecal administration, the patient developed acute hypotension and bradycardia, requiring vasopressor support to maintain circulation. Postoperatively, she exhibited lethargy, persistent hypotension, fever, decreased upper limb muscle strength, and complete paralysis of both lower limbs. Following symptomatic management, her condition gradually improved: hemodynamic stability was restored within 24 hours, and complete recovery of consciousness, motor, and sensory functions to preoperative baseline levels was achieved within 39 hours. The patient was discharged on postoperative Day 8 and showed no neurological sequelae during the two-week follow-up period. Conclusions: This case report demonstrates that inadvertent intrathecal injection of magnesium sulphate during anaesthesia can lead to severe complications. Local pharmaceutical manufacturers are advised to modify ampoule appearance, optimize internal risk-based segregation of high-risk medications, and enforce double-check protocols to reduce the recurrence of similar incidents.
