Essential Considerations in the Treatment of Intractable
Pain
Adequate
Treatment
The pharmacological treatment of
pain must follow the principles of treatment of any
condition. The correct medicine must be selected; the
proper doses prescribed; and the risks and side-effects
must be carefully monitored and weighed against the
benefits. With pain medications utilized for intractable
pain, the most serious considerations are for excessive
sedation, severe constipation, and underdosage. If the
patient is not adequately relieved of the pain, or is
relieved for only a part of the day, the treatment is
inadequate. From among the pain-killing drugs, one must
choose a medicine strong enough so that excessive
numbers of pills are not required to accomplish pain
relief. Because of the inclusion of phenacetin in
combination oral pain medicines, large numbers of pills
(greater than six to eight a day) should be avoided
through the use of a stronger class of pain reliever.
Sustained relief formulations are
preferable to short-acting, to effect sustained relief.
In severe pain, fentanyl patches and morphine-sulfate
patches and suppositories, should be considered. In the
most severe cases, in which oral and transdermal routes
are inadequate, implantable pumps and invasive blocks
are life-saving. If the pain is legitimate, it must be
treated aggressively and with pharmacological
sophistication.
Consideration must be also given
to what has been described as a neuropathic element in
pain, which is thought to arise from direct injury to
nerves and nervous tissue. Probably a factor in all
pain, neuropathic pain sometimes responds to medications
which stabilize nervous tissue activity, such as
Neurontin and Depakote. In some cases the patients pain
can be relieved by the addition of these medications,
which reduces the amount of opiate-derived medication
required to achieve sustained relief.
