Surgeries performed at Day – care surgical Unit (DSU) under Local Anesthesia (LA) are zero risk surgeries hence many patients with high risk for general/ spinal anesthesia can be undertaken. And those surgeries performed in DSU under general/ spinal anesthesia (GA/SA) have maximum mortality (Death rate) of 0.0007% only. This death rate is even less than the normal death rate.
