The provision of general anesthesia during endovascular therapy for acute ischemic stroke patients with large-vessel occlusions did not result in more infarct growth when compared with conscious sedation in a new randomized trial, contrary to previous findings.
Furthermore, the single-center, open-label, blinded-endpoint General or Local Anesthesia in Intra Arterial Therapy (GOLIATH) trial also reported that patients randomized to the general anesthesia (GA) group had improved functional outcomes on the modified Rankin Scale at 90 days, with a 91% greater likelihood for lower scores than with conscious sedation (CS) (odds ratio, 1.91; 95% confidence interval, 1.03-3.56).

The GOLIATH trial randomized patients to general anesthetic (n = 65) or conscious sedation (n = 63). The average age of the patients was 71.4 years and 48.4% of the cohort were women. The patients’ median National Institutes of Health Stroke Scale score was 18 (interquartile range [IQR], 14-21), and the initial infarct size was also comparable between the GA and CS groups, respectively (median [interquartile range], 10.5 [2.4-23.6] mL vs. 13.3 [5.2-31.1] mL; P = .26)
