Ongoing bleeding despite good nasal packing is a surgical emergency and can be treated by endoscopic evaluation of the nasal cavity under general anaesthesia to identify an elusive bleeding point or to directly ligate (tie off) the blood vessels supplying the nose. These blood vessels include the sphenopalatine , anterior and posterior ethmoidal arteries. More rarely the maxillary or a branch of the external carotid artery can be ligated. The bleeding can also be stopped by intra-arterial embolization using a catheter placed in the groin and threaded up the aorta to the bleeding vessel by an interventional radiologist.  There is no difference in outcomes between embolization and ligation as treatment options, but embolization is considerably more expensive.  Continued bleeding may be an indication of more serious underlying conditions. 
I had a flu shot in 1993 (I do not know what kind) when I was in my late 30’s. About 10 days later I started having severe ringing and buzzing in my right ear. I woke up in the middle of the night with no hearing in that ear. I saw an ENT doc that same day and started on steroids. Had the MRI which was all clear. I lost 100% of the hearing in my right ear. All the nerves were also affected, so a hearing aid will not help. It took a long time to recover…both the physical and emotional. I will never take another flu shot, and I research carefully before any immunization. I discovered that the shingles shot can also cause hearing loss…
Many doctors have told me that it was not the flu shot that caused my SSNHL; however, I was not ill and nothing else could have caused it.
Isn’t it good that we live in a world where everyone is entitled to their own opinion. Well at least the part of the world I preside in that is. You are saying that for Hellsing to be horror the protagonist has to in peril at some point but what about the horrors of war it portrays, the horror of damnation and the horror of immortality. That’s where the true horror of vampire movies lay, in the departure from humanity. Soulless, undead, forever damn to dwell in darkness and feed of the living. No family, friends or true love. Only darkness, death and eternal damnation.
