Monitoring nociception in patients with morbid obesity undergoing bariatric surgery.
Review in Saudi journal of anaesthesia. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Bariatric surgery is a rapidly developing field and presents a challenge for anesthesia management, especially in the treatment of acute postoperative pain. Severely obese patients have a greater risk of intra and postoperative complications due to their cardiovascular and respiratory pathophysiological alterations. Excessive fat also alters the normal metabolism of analgesic drugs, in particular opioids, thus reducing their therapeutic range and increasing the risk of reaching toxic doses with accumulation and overdose effects. Nociception, in contrast to pain, is not a subjective experience but a physiological response to a nociceptive stimulus, which manifests as objective modifications in vital parameters. An increasing number of monitoring methods have been approved in recent years, especially developed for the detection of intraoperative nociception to enable better control of opioid titration. This review aimed to provide an overview of the main monitoring systems commercially available devices, which could be used to monitor nociception during bariatric surgery. Eighteen studies evaluating the most widespread nociception monitoring systems were analyzed. These studies were mostly conducted on patients undergoing abdominal laparoscopic surgery, which is comparable to bariatric surgery in terms of pain stimulation. Intraoperative and postoperative opioid consumption were compared between patients subject to nociceptive monitoring and those in whom analgesia was guided by their changes in vital parameters. Although the devices seem able to optimize the anesthetic management of these patients, studies on bariatric populations are scarce and do not allow us to state whether the routine use of these tools can modify the patient's clinical outcome.
