Opioid Administration in Complex Ventilated Patients in a Surgical Intensive Care Unit.
Observational study in The Journal of surgical research, 2025. 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
introductionEffective pain management in the surgical intensive care unit (SICU) is challenging, particularly for ventilated patients requiring neuromuscular blockade (NMB) infusions or extracorporeal membrane oxygenation (ECMO) support. While opioids are effective, they pose risks like sedation, respiratory depression, and withdrawal. Data on how NMB and ECMO influence opioid utilization patterns in ventilated SICU patients remain limited. We hypothesized that NMB and ECMO are associated with increased opioid utilization. MATERIALS AND
methodsThis retrospective observational study was conducted at a single academic medical center. Data were extracted from the electronic health record and visualized using a business intelligence tool. Patients were grouped by ECMO status and then further stratified into four groups based on the combinations of ECMO and NMB. Statistical analyses included chi-square tests, t-tests, Wilcoxon rank-sum tests, and multivariable linear regression models.
resultsA total of 1550 patients were included in the study, including 23 ECMO-supported patients and 1527 non-ECMO patients. Within ECMO patients, NMB was associated with 265.1% higher opioid use (774.89 versus 212.24 MME/patient/d, P = 0.007), while non-ECMO patients with NMB had 226.5% higher opioid use (558.23 versus 170.97 MME/patient/d, P < 0.001). Among NMB patients, opioid use was similar between ECMO and non-ECMO patients (P = 0.112). Among non-NMB patients, opioid use was also similar between ECMO and non-ECMO patients (P = 0.725).
conclusionsNMB infusions were associated with increased opioid utilization in these patients, whereas ECMO alone was not significantly associated with opioid use. These findings underscore the need for strategies to reduce excessive opioid use in this complex population.
