What are the Accidents of Phlebotomy?
They are an Impostume, a Rhombus, an Echymosis, an Aneurism, Lipothymy, Swooning, and a Convulsion.
What is a Rhombus?
It is a small Tumour of the Blood which happens in the place where the Operation is perform'd either by making the Orifice too small, or larger than the Capaciousness of the Vessel will admit. The Rhombus is cur'd by laying upon it a Bolster dipt in fair Water, between the Folds of which must be put a little Salt, to dissolve and prevent the Suppuration.
How may it be perceiv'd that an Artery hath been prickt or open'd in letting Blood?
The Puncture of an Artery produceth an Aneurism; and the Opening of it causeth a Flux of Vermilion Colour'd Blood, which issueth forth in abundance, and by Leaps.
Are the Leaps which the Blood makes in running, a certain Sign that it comes from an Artery?
No, because it may so happen, that the Basilick Vein lies directly upon an Artery, the beating of which may cause the Blood of the
Basilica to run out leaping: Therefore these three Circumstances ought to be consider'd jointly, that is to say, the Vermilion Colour, the great quantity and the Leaps, in order to be assur'd that the Blood proceeds from an Artery.
How may it be discover'd that a Tendon hath been hurt in letting Blood?
