Capnography With Integrated Pulmonary Index for Preventing Hypoxemia During Pediatric Urologic Surgery Under Sedation: A Randomized Controlled Trial.
Trial report in Medical science monitor : international medical journal of experimental and clinical research, 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 Procedural sedation and analgesia (PSA) can relieve pain and anxiety during invasive procedures. Carbon dioxide (CO₂) monitoring or integrated pulmonary index (IPI) can reduce respiratory depression in adults with PSA, but the effect of the combination of these 2 methods on intraoperative hypoxemia in pediatric urologic surgery is unclear. This study was conducted to determine whether capnography combined with IPI could lessen intraoperative hypoxemia during pediatric urinary procedures with PSA. MATERIAL AND METHODS We conducted a randomized controlled trial (ChiCTR 2300073943). Children referred for urinary procedures with PSA were randomly assigned to either a control group with standard monitoring or an intervention group with standard monitoring combined with capnography and IPI monitoring. The primary outcome was intraoperative hypoxemia. Secondary outcomes were severe intraoperative hypoxemia, airway management, and perioperative complications. RESULTS A total of 133 patients completed the analysis (67 in the intervention group and 66 in the control group). Compared with the control group, the incidence of intraoperative oxygen saturation decline was significantly lower in the intervention group (34.33% vs 56.06%, odds ratio=0.410, 95% confidence interval: 0.203-0.825, P=0.012). Simultaneously, the incidence of severe oxygen desaturation (SpO₂ <90%) was also significantly reduced in the intervention group (19.40% vs 36.40%, odds ratio=0.421, 95% confidence interval: 0.192-0.925, P=0.034). Regarding airway management interventions, the intervention group exhibited a higher frequency of jaw thrust maneuvers (1.84±1.31 vs 1.17±1.12 times, P=0.004) and a significantly reduced need for invasive positive-pressure ventilation (1.64±1.31 vs 2.39±1.48, P=0.002). No differences in other airway management techniques or perioperative complications were observed between the 2 groups. CONCLUSIONS The addition of capnography and IPI monitoring to standard monitoring reduces the risk of intraoperative hypoxemia in pediatric urologic surgery and reduces the need for aggressive ventilation through early intervention.
