Study summary

Nasal surgeries are common day case procedures. Although surgical complications are rare, bleeding decreases surgical field visibility and may cause vascular, orbital or intracranial complications in addition to failure of procedure. So, it is crucial to maintain hypotensive anaesthesia to optimize the surgical field.
