Significantly more patients in the GA group than in the CS group experienced a decrease of greater than 20% in mean arterial pressure (MAP) (87.7% vs. 34.9%; P = .001). However, when MAP dropped below 70 mm Hg, the duration was non-significantly longer for CS patients than for GA patients (6.5 [2-13] minutes vs. 2 [1-5.5] minutes; P = .09).
A longer delay from arrival at the neurointerventional suite to groin puncture was also seen for patients in the GA group. But the median difference of 9 minutes was “acceptable in the context of the much longer overall time from stroke onset to treatment and from stroke onset to reperfusion, which was not significantly different between the competing arms,” the authors said.
The authors said that overall their findings supported GA as a viable anesthetic approach during EVT. “Contrary to numerous nonrandomized studies that have reported better outcomes with CS, the GOLIATH trial shows signals in favor of GA for multiple endpoints,” the research team wrote. “Performing EVT under GA, compared with CS, does not result in worse tissue or clinical outcomes when using a GA protocol that limits the time delay for intubation (less than 10 minutes) and blood pressure level within recommended limits (systolic blood pressure greater than 140 mm Hg and MAP greater than 70 mm Hg).”
The trial was funded by Aarhus University Hospital. One author reported research grants from Penumbra and Neuravi, and another author reported a research grant from Health Research Fund of Central Denmark Region.
