1 · What the graph read from it

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.

2 · The registry

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

Purpose: The oculocardiac reflex (OCR) is a frequent and potentially hazardous complication during pediatric strabismus surgery. Achieving hemodynamic stability while ensuring rapid recovery is critical in day-case anesthesia. This study aimed to evaluate the efficacy of a sub-anesthetic dose of esketamine in reducing the incidence of OCR in children undergoing day-case strabismus surgery under total intravenous anesthesia (TIVA). Patients and Methods: This prospective, randomized, double-blind, placebo-controlled trial enrolled 204 children (aged 2-12 years, ASA I-II) scheduled for elective strabismus surgery. Patients were randomized (1:1) to receive either intravenous esketamine (0.2 mg/kg) or an equal volume of normal saline following laryngeal mask airway insertion. All patients received standardized TIVA with propofol and remifentanil. The primary outcome was the overall incidence of OCR (defined as a heart rate decrease >20% from baseline or arrhythmia upon muscle traction). Secondary outcomes included OCR incidence during three distinct surgical stages: Stage I (conjunctival incision), Stage II (active muscle mobilization and dissection), and Stage III (static sustained muscle traction), as well as severe OCR (<50 bpm), and postoperative recovery quality. Results: The overall incidence of OCR was significantly lower in the esketamine group compared to the control group (38.2% vs 70.6%; P < 0.05). Heart rates dynamics varied by stage, with the highest OCR incidence occurring during Stage II (37.3% vs 70.6%; P <0.05) compared to Stage III (1.0% vs 6.9%; P =0.071) in both groups. Heart rates in the esketamine group were significantly higher during conjunctival incision (Stage I) and muscle dissection (Stage II) (P < 0.001). For both groups, Stage II was associated with the highest incidence of OCR. Although the incidence of severe OCR was lower in the esketamine group (2.9% vs 8.8%), the difference was not statistically significant. There were no significant differences between groups regarding postoperative nausea and vomiting, emergence agitation, or time to discharge. Conclusion: A single sub-anesthetic dose of esketamine (0.2 mg/kg) effectively reduces the incidence of OCR and enhances hemodynamic stability in children undergoing day-case strabismus surgery. This regimen provides a safe prophylactic strategy without compromising recovery quality or increasing postoperative adverse events.
