Intravenous lidocaine enhances the efficacy of ondansetron and dexamethasone in postoperative vomiting prophylaxis among high-risk children.

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
A combination of dexamethasone, ondansetron, and total intravenous anaesthesia (TIVA) is recommended as prophylaxis for preventing postoperative vomiting (POV) in high-risk children. Implementing TIVA in paediatric patients undergoing anaesthesia presents challenges due to its excessive inter-individual variability and difficult estimation. Regarding lidocaine's antiemetic effect in paediatric patients, incorporating lidocaine can mitigate POV in high-risk children. Among 204 children undergoing elective tonsillectomy (with/without adenoidectomy), those with postoperative vomiting score ≥ 4 was randomised into Group C (saline) and Group L (lidocaine). The primary outcome was POV incidence within the first 24 h after surgery. The POV incidence differed among 15 patients in Group C (14.7%) and 5 in Group L (4.9%) presenting with one or more episodes of POV (P = 0.019). The secondary outcome was the number of coughs within the first 30 min after surgery. The number of coughs within the first 30 min after surgery significantly differed between Group L (0 [0-0.125]) and Group C (1 [0-2]) (P = 0.007). Significant between-group differences in the time to extubation were also observed, with a 3-min longer time in Group L. A lower percentage of patients experienced adverse events in Group C (2.2%) compared with Group L (1.1%) (P = 0.567); no severe events occurred. Adding intravenous lidocaine to ondansetron and dexamethasone was effective in reducing the POV incidence and extubation coughs in high-risk children following volatile anaesthesia for tonsillectomy.
