Effect of Lidocaine on Ciprofol Dosage and Efficacy in Patients Who Underwent Gastroscopy Sedation.
Trial report in Medical science monitor basic research, 2024. 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
BACKGROUND Intravenous ciprofol is a short-acting sedative with minimal respiratory and circulatory suppression and limited analgesia. Intravenous lidocaine provides analgesia during surgical procedures. This study included 70 patients who underwent gastroscopy with analgesia and aimed to evaluate the effects of intravenous lidocaine on the dose of ciprofol required to produce 50% of the maximal effect (ED50). MATERIAL AND METHODS Seventy patients scheduled for elective painless gastroscopy were randomly assigned into 2 groups: group L (n=35, received ciprofol and 1.5 mg/kg lidocaine) and group S (n=35, received ciprofol and normal saline). The primary outcomes measured were the ED50 and the 95% effective dose (ED95) of ciprofol, determined using the modified up-down sequential method and Probit analysis. Secondary outcomes included induction, operation, and recovery times; monitoring of vital signs such as mean arterial pressure, heart rate, and oxygen saturation; and evaluation of postoperative adverse reactions, including sore throat, nausea, vomiting, abdominal pain, and satisfaction scores from endoscopists and anesthesiologists. RESULTS The ED50 of ciprofol in group L was 0.315 mg/kg (95% CI, 0.291-0.342 mg/kg), which was significantly lower than that in group S, 0.42 mg/kg (95% CI, 0.371-0.491 mg/kg). Additionally, group L exhibited shorter induction and recovery times, a lower incidence of postoperative sore throat, and a temporary drop in blood pressure following induction. CONCLUSIONS Intravenous lidocaine during painless gastroscopy reduces the required ciprofol dose, shortens induction and recovery times, and lowers the incidence of postoperative complications, such as sore throat. These findings support its effective role in improving sedation quality and patient outcomes during gastroscopy.
