Influence of the end inspiratory pause on ventilatory efficiency and respiratory mechanics in patients undergoing robotic surgery under a tailored open lung approach: a prospective-paired study.

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
introductionThe effect of modifying the end inspiratory pause (EIP) on the variations in the physiological dead space (VDphys) in patients undergoing robotic surgery ventilated under a tailored open lung approach has not been addressed before. MATERIAL AND
methodsThis prospective-paired study was carried out in a tertiary hospital. Following an alveolar recruitment manoeuvre (ARM) and the application of a tailored open-lung positive end-expiratory pressure (PEEPOL), participants consecutively received three EIP levels (30%, 40%, and 10%). The sequence was repeated after pneumoperitoneum and the Trendelenburg position and following a second ARM for patients with suspected lung collapse based on an Air test.
resultsEighteen adult subjects were included. The use of an EIP of 10% was asso-ciated with a higher VDphys, both before pneumoperitoneum: 210 mL (IQR 200-237) vs. 197 mL (IQR 173-217) and 196.8 (IQR 185-218) with EIP 30% and 40%, respectively (
conclusionsThe use of an EIP of 30-40% compared to 10% in patients undergoing robotic surgery optimises lung mechanics and minimises ventilation inefficiencies both before and during the establishment of pneumoperitoneum and Trendelenburg positioning.
