Infusion therapy

Infusion therapy is a supervised inpatient treatment in which medication is delivered slowly into the bloodstream over several days. It is considered for selected people with severe neuropathic or widespread pain that has not responded to other treatment, and is used as part of a broader plan.

Some pain conditions involve changes in how the nervous system itself processes signals, rather than ongoing damage to tissue. In this group, treatments aimed at a structure — injections, surgery — often do little, because the problem is not at the structure. Supervised infusion therapy is one of the options considered in this situation.

Who it is considered for. People with severe neuropathic pain, complex regional pain syndrome, or widespread pain that has persisted despite adequate trials of other approaches, and where the impact on daily life is substantial. It is not a first-line treatment and is not offered on request; it follows a full assessment in which the likely mechanisms of your pain are established and other options considered.

Why it is done in hospital. The medication requires continuous monitoring, adjustment and nursing support. Admission allows dose to be titrated to response, side effects managed as they arise, and safety maintained throughout.

What is involved. Following assessment and agreement to proceed, you are admitted for a planned period. Medication is given slowly and continuously through a fine cannula. Observations are monitored throughout and the rate adjusted according to your response and any side effects. You are reviewed daily. You are discharged with a follow-up plan.

What to expect from it. Response varies substantially. Some people get a meaningful period of reduced pain; others get little. It is not a cure, and where it helps, the benefit is usually a window rather than a permanent change — which is why what happens afterwards matters as much as the admission itself. A rehabilitation plan is set up in advance so the window is used.

Who it is not suitable for. Suitability depends on your other medical conditions, your current medications, and your mental health history. Some conditions make this treatment inappropriate. This is assessed carefully, and Dr Martin will tell you directly if he does not think it is the right option.

Side effects. These are explained in full at assessment and again before admission, and are monitored throughout the admission. Blood tests are taken before and during treatment as part of routine monitoring.

Access. Assessment is by specialist referral. Whether this treatment is appropriate for you is a decision made in consultation, not in advance.
