Outcomes
Primary outcome [1] 3202 0
Correlation between Skin Conductance and Hypotension following spinal anaesthesia.
Timepoint [1] 3202 0
For this purpose, the lowest blood pressure reading within 15 minutes after spinal anaesthesia is compared to the pre-spinal baseline value.
Secondary outcome [1] 5342 0
Sensitivity and specificity of Skin conductance values to predict hypotension.
Timepoint [1] 5342 0
For this, a pre-spinal baseline reading of Skin conductance variables and blood pressure are obtained. This reading is than compared with the lowest blood pressure reading up to 15 minutes after spinal anaesthesia.
