Does sleep matter before surgery? The impact of preoperative sleep quality on pain and analgesic requirement after percutaneous nephrolithotomy.

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
purposePostoperative pain is a significant clinical issue that delays recovery and increases the risk of complications. Sleep quality is a modifiable factor that can influence the perception of postoperative pain. This study aimed to evaluate the association between preoperative sleep quality and postoperative pain scores, analgesic consumption, and sedation demand in patients undergoing percutaneous nephrolithotomy (PCNL).
methodsIn this prospective observational study, 92 adult patients scheduled for elective PCNL were enrolled. In the preoperative period, the Pittsburgh Sleep Quality Index (PSQI) and the Richards-Campbell Sleep Questionnaire (RCSQ) were administered, and patients' requests for sedation were recorded. Postoperative pain was assessed at 0, 6, and 24 h using the Numerical Rating Scale (NRS) during both rest and movement. The need for additional analgesic administration was also recorded.
resultsPatients classified as having poor sleep quality by either PSQI or RCSQ had significantly higher pain scores at all postoperative time points during both rest and movement (p < 0.01). The incidence of additional analgesic use and sedation request was significantly higher in the poor sleep quality group. No significant differences in age, sex, BMI, or surgery duration were observed between groups.
conclusionPoor preoperative sleep quality is associated with increased postoperative pain scores, increased additional analgesic use, and more frequent sedation requests in patients undergoing PCNL. Routine assessment of sleep quality may help identify high-risk patients and optimize perioperative pain management strategies.
