SEROUS ABSCESS. 
189 
Treatment,' — Rest, a purgative and frequent fomentation, which 
usually brings about absorption of the effused material. Should the 
swelling increase and be accompanied by doughiness, increased pain, 
heat, tenderness and fever, it may be inferred that matter has formed 
(purulent abscess), and must accordingly be evacuated without delay 
and treated as laid down. 
Note. — In operations such as opening abscesses and cysts ^ slitting 
up sinuses, removing small tumours, etc., gratifying results are 
obtained by the injection of Eudrenine^^ into the surrounding 
tissues. This preparation is a combination of Eucaine and Adrenalin 
whereby the properties of the two drugs are combined, the former 
renders the part painless while the latter prevents bleeding. It 
is employed by injecting deeply 75 to 20 minims with a hypodermic 
syringe at various points around and into the part to be operated 
on and waiting 10 to i ^ minutes to allow it to take effect. Three- 
quarters of an ounce may be injected. Messrs. Parke Davis & 
Co., who have Agents in Bombay and Simla, supply Tabloids, etc., 
with full directions for use. 
The preparation might be made up of the strength recommended 
by Wallis Hoare,^ viz. :— 
Eucaine Hydrochloride 
Adrenalin Chloride 
in each cubic centimetre [about minims).
