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

introductionPain is still severe after single-port video-assisted thoracoscopic (SPVAT) lung wedge resection. We observed the effect of single-injection thoracic paravertebral block (TPB) via the intrathoracic approach for analgesia after SPVAT lung wedge resection.

methodsSixty patients undergoing SPVAT lung wedge resection were randomly divided into a control group and an observation group. All patients underwent TPB via the intrathoracic approach at the T4 level with a scalp needle before closing the chest. The patients in the observation group received 20 ml 0.375% ropivacaine at the T4 level, and the patients in the control group received 20 ml of 0.9% saline. A patient-controlled intravenous analgesic (PCIA) pump with sufentanil was attached to all patients after surgery. The sufentanil consumption and number of PCIA presses in the first 24 h after surgery were recorded. The visual analogue scale (VAS) scores (during rest and coughing) were recorded at 6 h, 12 h, 24 h, and 36 h after surgery. The incidence of adverse reactions after surgery were recorded.

resultsThe sufentanil consumption in the observation group was significantly lower than that in the control group (34.2 ± 1.9 µg vs. 52.3 ± 2.3 µg; P < 0.001). The VAS score at 6, 12, and 24 h after surgery, the incidence of adverse reactions after surgery in the observation group were significantly lower than those in the control group (all P < 0.05). The number of PCIA presses in the observation group was significantly lower than that in the control group [0 (0-0) times vs. 3 (2-4) times, P < 0.001].

conclusionsSingle-injection TPB via the intrathoracic approach under thoracoscopic direct vision is easy to perform and can effectively alleviate postoperative pain after SPVAT lung wedge resection, with fewer adverse reactions.
