  Purpose

Neuropathic (nerve pain) following amputation of a limb is very common, affecting 60-80% of patients (Sherman et al, 1984). It can prolong their recovery making it difficult to fit protheses and mobilise. Current treatment options are limited and existing painkillers have significant side effects. Nevertheless there is some evidence that pre-emptive analgesia (pain relief provided prior to the surgery) has additional benefits after the surgery (Ypsilantis & Tang, 2010) Qutenza (topical capsaicin 8%)is a novel analgesic agent which is applied directly onto the skin. It works by desensitising to pain receptors in the skin (Nolano et al., 1999) and has been shown to be effective in reducing neuropathic pain in other conditions (Backonja et al., 2008) We propose to evaluate the use of Qutenza for pre-emptive analgesia in patients undergoing amputation of a limb. This is a small, pilot, randomised controlled study of 30 patients undergoing lower limb amputation who will have Qutenza or active control applied prior to surgery. They will be followed up for 12 weeks post-operatively with regular assessment of pain scores, quality of life and wound healing.

Primary Outcome Measures:
  • Chronic neuropathic pain [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    Chronic neuropathic pain as assessed by Visual Analogue Pain Score


Secondary Outcome Measures:
  • Neuropathic pain [ Time Frame: 1 weeks, 6 weeks, 12 weeks ] [ Designated as safety issue: No ]
    Assessed using VAS and Brief Pain Inventory

  • Acute post-operative pain [ Time Frame: Day 1, 3, 7 ] [ Designated as safety issue: No ]
    Assessed by Visual Analogue Pain Score

  • Wound healing [ Time Frame: 1 week ] [ Designated as safety issue: Yes ]
    Assessed using standardised, validated wound healing tools

  • Quality of life [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    Assessed by EQ-5D

  • Safety and tolerability [ Time Frame: 1 day, 12 weeks ] [ Designated as safety issue: Yes ]
    Skin will be assessed for breaks/ blisters and tolerability including the need for rescue analgesia will be recorded
