Meta AnalysisSufentanil versus fentanyl for pain relief in labor involving combined spinal-epidural analgesia: a systematic review and meta-analysis of randomized controlled trials.
To systematically compare the efficacy and safety of sufentanil versus fentanyl for pain relief in labor involving combined spinal-epidural analgesia (CSEA), a systematic review and meta-analysis of randomized controlled trials targeting parturients requesting labor analgesia was conducted. ⋯ Existing evidence suggests that compared with fentanyl, sufentanil used for analgesia in combined spinal-epidural during labor is more effective in extending the duration of spinal analgesia, and may be safer for the infant. There was overall low clinical and statistical heterogeneity among the included studies. For all outcomes, variations caused by heterogeneity across trials were acceptable. Thus the findings of this meta-analysis may provide additional evidence for future clinical practices of pain relief in labor involving CSEA. Stronger evidence supporting this conclusion will require data from more high-quality and multicenter randomized controlled trials.

Clinical TrialIntake of aspirin prior to metamizole does not completely prevent high on treatment platelet reactivity.
Metamizole can sterically inhibit aspirin (ASA) from binding to cyclooxygenase 1 (COX1). It is recommended that ASA should be taken 30 min prior to metamizole to maintain the irreversible inhibition of arachidonic acid (AA)-induced platelet aggregation. We aimed to analyse the inhibitory effect of ASA and metamizole on AA-induced platelet aggregation over the course of the day. ⋯ Co-medication of ASA and metamizole significantly influences platelet inhibition with variations during the day and can cause HTPR in patients taking ASA prior to metamizole or simultaneously.
