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

objectiveTo evaluate the efficacy of lidocaine patch applied around wound in laparoscopic colorectal surgery in reduction of postoperative pain and illus compared to intravenous lidocaine infusion and placebo.

backgroundPostoperative illus and pain after colorectal surgery is a challenging problem associated with increased morbidity and cost. Inflammatory response to surgery plays crucial rule in inducing postoperative illus. Systemic local anesthetics proved to have anti-inflammatory properties that may be beneficial in preventing ileus added to its analgesic actions. The lidocaine patch evaluated in many types of pain with promising results. We try to evaluate the patch in perioperative field as a more simple and safe technique than the intravenous route. MATERIALS AND

methodsProspective, randomized, controlled study was conducted, comparing three groups. Group 1 (placebo) received saline infusion, group 2 received i.v. lidocaine infusion after induction of anesthesia, 2 mg/min if body weight >70 kg or 1 mg/min if body weight <70 kg, group 3 received lidocaine patch 5%, three patches each one divided into two equal parts and applied around the three wounds just before induction. Data collected were, pain scores (VAS), morphine consumption, return of bowel function, pro-inflammatory cytokines plasma levels and plasma lidocaine level.

resultsPain intensity (VAS) scores at rest and during coughing were significantly lower during the first 72 h postoperative in i.v. lidocaine group and patch group compared to the placebo group. Mean morphine consumption were significantly lower in the i.v. lidocaine group and patch group compared to placebo group. Return of the bowel function was significantly earlier in i.v. lidocaine group in comparison to the other groups. Proinflammatory cytokines (IL6, IL8, and C3a) were significantly lower in i.v. lidocaine group compared to the other two groups.

conclusionThe lidocaine patch was equal to i.v. lidocaine infusion in decreasing pain scores and morphine consumption but not in acceleration of bowel function return.
