Clinical effects of prolonged preoperative fasting in breast cancer surgery: a prospective cohort study.
Observational study in BMC surgery, 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
backgroundPreoperative fasting reduce the risk of pulmonary aspiration during induction of anaesthesia. However, scientific documentation on the correlation between prolonged preoperative fasting and patient discomfort is limited. The aim of the present study was to investigate whether the duration of preoperative fasting correlates with pre- and postoperative patient discomfort, the duration of stay at postoperative care unit and the occurrence of surgical complications within 30 days.
methodsThis prospective observational study included 50 women undergoing elective breast cancer surgery. The Numerical Rating Scale (NRS) was used to assess hunger, thirst, nausea, pain, and anxiety. Patient characteristics, surgical data and occurrence of surgical complications were collected from medical records. Statistical analyses included Sperman’s rank correlation, Pearson’s correlation, Wilcoxon signed rank test, and logistic regression analysis.
resultsThe mean fasting duration was 15.1 h for solid food and 12.1 h for fluids. A positive association was observed between fasting duration for solid food and nausea prior to surgery (p = 0.067), although not reaching statistical significance. There was no significant correlation between duration of fasting for both solids and fluids and patient discomfort before and after surgery, nor with the duration of stay on the postoperative care unit, nor with the surgical complication rate within 30 days.
conclusionsNo correlation was observed between the duration of preoperative fasting and patient discomfort, the length of stay in the postoperative care unit, or the incidence of surgical complications. Notably, fasting durations highly exceeded the recommended six hours for solids and two hours for clear fluids.
