Clinical Application of Bilateral Nasopharyngeal Airway in Painless Colonoscopy for Obese Patients.

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
Objective: This study aims to evaluate the safety and efficacy of using bilateral nasopharyngeal airways (NPA) during colonoscopic polypectomy performed under sedation anesthesia in obese patients. Methods: Ninety obese patients undergoing colonoscopic polypectomy under elective sedation anesthesia at Shanghai Shuguang Hospital were randomly allocated to two groups. Patients in group B had a nasopharyngeal airway inserted bilaterally after induction of anesthesia, whereas patients in group U had a nasopharyngeal airway inserted in only one nostril. Spontaneous breathing was maintained in both groups. The primary observation parameter was the incidence of oxygen saturation (SpO2) ≤ 92% during anesthesia, while secondary observation parameters included preoperative, intraoperative, and post-operative SpO2 levels, mean arterial pressure (MAP), heart rate (HR), dosage of propofol, duration of the operation, time to anesthesia recovery, need for emergency airway intervention, and occurrence of other adverse events. Results: Hypoxia occurred in 5 out of 45 patients (11.1%) in group B, whereas it was observed in 14 out of 45 patients (31.1%) in group U (P < 0.05). Patients in group B exhibited higher SpO2 levels during and after surgery compared to those in group U (P < 0.05). Furthermore, the decrease in intraoperative and post-operative SpO2 levels from baseline was significantly lower in group B compared to group U (P < 0.05). The number of emergency airway interventions, operation time, propofol dosage, and anesthesia recovery time were significantly lower in group B compared to group U (P < 0.05). However, there were no significant differences in MAP, HR, or the incidence of adverse events between the two groups (P > 0.05). Conclusion: The utilization of bilateral nasopharyngeal airway placement proves to be an effective strategy in decreasing the occurrence of hypoxia among obese patients undergoing colonoscopy under sedation anesthesia, thereby improving procedural safety.
