Remote Ischemic Conditioning to Reduce Perihematoma Edema in Patients with Intracerebral Hemorrhage (RICOCHET): A Randomized Control Trial
Abstract
Background: Early perihematomal edema (PHE) growth is associated with worse functional outcomes at 90 days. Remote Ischemic conditioning (RIC) may reduce perihematomal inflammation if applied early to patients with intracerebral hemorrhage (ICH). We hypothesize that early RIC, delivered for seven days in patients with spontaneous ICH, may reduce PHE growth. Methods: ICH patients presenting within 6 h of symptom onset and hematoma volume Results: Sixty patients were randomized with a mean ± SD age of 57.5 ± 10.8 years, and twenty-two (36.7%) were female. The relative baseline median PHE were similar (RIC group 0.75 (0.5–0.9) mL vs. SC group 0.91 (0.5–1.2) mL, p = 0.30). The median EEDs at baseline were similar (RIC group 0.58 (0.3–0.8) cm vs. SC group 0.51 (0.3–0.8) cm, p = 0.76). There was no difference in the median day 7 EED (RIC group 1.1 (0.6–1.2) cm vs. SC group 1 (0.9–1.2) cm, p = 0.75). Conclusions: Early RIC therapy delivered daily for seven days was feasible. However, no decrease in EED was noted with the intervention.
