Sputum can be disinfected by all EXCEPT:
|D|| Chlorhexidine |
Sputum: This is best received in gauze or paper handkerchiefs and destroyed by burning. If the amount is considerable (as in TB hospitals), it may be disinfected by boiling or autoclaving for 20 minutes at 20 lbs pressure. Alternatively, the patient may be asked to spit in a sputum cup half filled with 5 per cent cresol. When the cup is full, it is allowed to stand for an hour and the contents may be emptied and disposed off.
Chlorhexidine (hibitane):This is one of the most useful skin antiseptics. Highly active against vegetative gram-positive organisms, and moderately active against gram-positive microbes. It is soluble in water and alcohol. It is inactivated by soaps and detergents. 0.5 per cent alcoholic or aqueous solutions can be used as effective hand lotions. Creams and lotions containing 1 per cent chlorhexidine are recommended for burns and hand disinfection
