What are CAM’s ?
‘Diagnosis, treatment and /or prevention

by contributing to a common whole, by
satisfying a demand not met by orthodoxy
or by diversifying the conceptual
frameworks of medicine.’

practitioners stand legally with
regard to CAM’s
They are mostly legal but practitioners are not regulated.
They can be freely prescribed in the UK, but not in all
European countries.
They are considered drugs/treatments and it is therefore
now viewed as good practice to include them in history
taking when assessing patients.
They are not without side effects and contra indications
and these should be considered when carrying out
history taking & assessment.

N-Acetyl Cysteine (NAC)
This is a specially modified form of the
dietary amino acid, cysteine.
 This is thought to help loosen the thick
crusty secretions that block oil-secreting
glands if taken orally.
In a study by Yalcin et al(2002)
This studied the effect of N-Acetyl Cysteine on
50 patients with chronic posterior blepheritis and
found significant improvement.
The limitations of this study are its small size
and the fact it was not a blind study.
An interesting study but more research would
be advisable before it is recommended.

year old system of medicine based on

Nurses must consider the ethical
Autonomy - which allows the patient to make
choices in treatment.
Non-maleficence - which means not harming
patients when providing treatment.
Beneficence - using safe and effective
treatments and discussing with patients research
about the possible harm and benefits.
Justice - ensuring all patients have equal access
to treatments.
