The role of gastric ultrasound in anaesthesia for emergency surgery: A review and clinical guidance.
Article in European journal of anaesthesiology and intensive care, 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
backgroundThe timing and technique of anaesthesia are challenging in patients with a history of recent food intake. The presence of gastric contents increases the risk of aspiration, potentially resulting in acute lung injury, pneumonia, or death. Delayed gastric emptying complicates the estimation of aspiration risk. Surprisingly, there are no fasting guidelines for emergency surgery. Point-of-care gastric ultrasound is a time-efficient, cost-efficient and accurate bedside tool with which to estimate residual gastric content and to guide decision-making in airway management and timing of general anaesthesia. This review summarises the prevailing concepts of ultrasound-guided gastric content assessment for emergency surgery.
methodsMedline and Embase databases were searched for studies using ultrasound for the evaluation of gastric content in adults scheduled for emergency surgery.
resultsFive prospective observational studies representing 793 emergency surgery patients showed that the incidence of 'full stomach' was between 18 and 56% at the time of induction. Risk factors for a full stomach before emergency surgery were abdominal or gynaecological/obstetric surgery, high body mass index and morphine consumption. No correlation between preoperative fasting time and the presence of a full/empty stomach was found. No deaths due to aspiration were reported.
conclusionThe preoperative presence of gastric content before emergency surgery is high and the estimates used for clinical management are unreliable. This review demonstrates that gastric ultrasound is a valuable tool for evaluating gastric content. A flow chart for medical decision-making using gastric ultrasound before emergency surgery was developed to assist in clinical decision-making. The validity and practical applicability should be assessed in future studies.
