Effect of esketamine vs sufentanil adjunct to propofol deep sedation on the incidence of oxygen-desaturation in elderly patients undergoing urologic surgeries: a randomized, double-blind, controlled trial.
Trial report in BMC anesthesiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundPropofol deep sedation/anesthesia combined with analgesics is always used in minimally invasive urologic surgeries in elderly patients.Oxygen-desaturation is one of the most frequent respiratory complications susceptible to other life-threatening accidents for elderly patients during propofol sedation. The purpose of this study is to evaluate the efficacy and safety of low-dose esketamine adjunct to propofol sedation on the occurrence of oxygen-desaturation, hypotension, propofol requirements and other related adverse events compared to sufentanil for elderly patients undergoing urologic surgeries.
methodsNinety four elderly male patients undergoing transurethral bladder lesion resection or ureteroscopic ureteral laser lithotripsy were randomly enrolled into esketamine/propofol group (SK group, n = 47) or sufentanil/propofol group (SF group, n = 47). The patients in SK group received 0.25 mg/kg esketamine and 1.5 mg/kg propofol for anesthetic induction and SF group received 0.1 μg/kg sufentanil and 1.5 mg/kg propofol. Sedation was Maintained with 4-6 mg/kg/h propofol infusion. The primary outcome was the incidence of oxygen-desaturation during the surgeries. Second outcomes included induction time, hemodynamic changes, intraoperative propofol dosage, operation duration and anesthesia duration, recovery time, other related adverse events and rescue medication.
resultsThe incidence of oxygen-desaturation was 34.0% (16 of 47) in SK group compared to 68.1% (32 of 47) in SF group with a significant difference (risk ratio, 0.50; 95% confidence interval, 0.32-0.78; P < 0.001). The overall severity of hypoxiemia was mild in SK group (22/9/16 vs 6/9/32, P = 0.00072). Propofol requirements, induction time were all much lower in SK group than those in SF group (P < 0.001). More hemodynamic stability was observed in SK group compared to SF group. The protective factors of oxygen-desaturation were esketamine (OR:0.26, CI: 0.08 to 0.86, P = 0.027), transurethral bladder lesion resection (OR:0.14, CI: 0.03 to 0.64, P = 0.011). Weight was a hazard factor of OD (OR:1.07, CI: 1.00 to 1.15, P = 0.048). Postoperative sedation score, MMSE, VAS score, incidence of nausea and vomiting were similar in both groups (P > 0.05).
conclusionsEsketamine combined with propofol sedation used in minimal invasive urologic surgeries, could reduce the incidence of oxygen-desaturation, decrease propofol requirements, stabilize hemodynamics and didn't affect the postoperative recovery and neurological function of elderly patients.
