Impact of pneumoperitoneum pressure on cardiac output in laparoscopic surgery.
Trial report in BMC anesthesiology, 2025. 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
objectiveTo assess the impact of pneumoperitoneum pressure on cardiac output (CO) in patients undergoing laparoscopic surgery using transesophageal echocardiography.
methodsFifty patients (26 men, 24 women; age, 55-85 years old) who scheduled for laparoscopic colorectal cancer resection under general anesthesia at the First People's Hospital of Taicang (March 2021-December 2022) were enrolled. Patients were randomly assigned to three groups based on pneumoperitoneum pressure: group A (10 mmHg), group B (12 mmHg), and group C (14 mmHg). Left ventricular outflow tract diameter (LVOT) and velocity time integral (VTI) were measured using transesophageal echocardiography to calculate CO).
resultsBaseline characteristics and intraoperative data were comparable among groups (P > 0.05). Post-anesthesia, heart rate, mean arterial pressure (MAP), systolic blood pressure (SBP), and diastolic blood pressure (DBP) showed no significant differences among groups (P > 0.05). However, CO in all groups was lower than normal reference values after anesthesia induction (P < 0.05) and further declined following pneumoperitoneum establishment (P < 0.05). Group C exhibited significantly lower CO than Groups A and B five minutes after pneumoperitoneum initiation (P < 0.05).
conclusionPneumoperitoneum pressure significantly impacts CO during laparoscopic surgery. Transesophageal echocardiography provides an effective method for monitoring hemodynamic changes and optimizing perioperative management.
