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

objectivesThe objective of the present study is to evaluate postoperative analgesic outcome of the continuous bilateral transversus abdominis plane (TAP) block using bupivacaine infusion through an epidural catheter inserted through laparoscopic ports. PATIENTS AND

methodsNinety patients assigned for laparoscopic sleeve gastrectomy (LSG) were divided into two equal groups according to postoperative analgesia: Control group received IV morphine, and TAP group received bupivacaine 0.25% continuous infusion TAP block through epidural catheters introduced through laparoscopic ports, grasped, and inserted in laparoscopically prepared TAP. Catheters were removed 24 h postoperatively. Frequency and severity of postoperative pain were assessed using numeric rating scale (NRS). Cumulative pain score, number of requests, and total dose of administered rescue analgesia were recorded.

resultsPain scores were significantly lower throughout 24 h postoperative with a significantly lower cumulative score in the TAP group compared to the control group. Twenty-four patients in the TAP group did not require rescue analgesia, and 17 patients required it once with a significantly higher frequency of patients having a higher number of rescue analgesia requests in the control group. The mean of number of patients requested rescue analgesia; the number of requested doses and total dose of morphine received was significantly lower in the TAP group. Mean time till first ambulation and oral intake was significantly shorter, and morphine-related side effects were significantly lower in the TAP group. Total and differential satisfaction scores were significantly higher in the TAP group.

conclusionContinuous bupivacaine TAP block provided through an epidural catheter passed through laparoscopic ports improved postoperative outcome of LSG in terms of reduced postoperative pain scores, sparing morphine consumption, and early recovery items.
