Further study details as provided by Xijing Hospital:

Primary Outcome Measures:
  • visual analogue scales (VAS), the mcgill pain questionnaire (MGPQ). [ Time Frame: after HBO treatment ]

Secondary Outcome Measures:
  • visual analogue scales (VAS), the mcgill pain questionnaire (MGPQ),pain frequency, titration of dosage, clinical global impression (CGI) [ Time Frame: at monthly intervals for the subsequent 6 after hyperbaric oxygen (HBO) treatment ]

Estimated Enrollment: 30
Study Start Date: April 2008
Estimated Study Completion Date: April 2009
Estimated Primary Completion Date: January 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: A,2, II Procedure: Hyperbaric oxygen, Mock hyperbaric chamber

Hyperbaric oxygen treatment for 10 days in treatment groups and mock hyperbaric chamber treatment for 10 days in control groups.

Hyperbaric oxygen treatment: While in the hyperbaric chamber the subjects breathe 100% oxygen saturation with mask at 2.0bars.

Mock hyperbaric chamber treatment: The subjects breathe air freely in the imitation environment chamber at 1.0bars.

Other Name: the delivery of oxygen in a pressurised chamber

Detailed Description:
Trigeminal neuralgia(TN) is a recurrent severe shooting neuropathic pain. Treatment of this pain continues to be a challenge in clinical pain management. Hyperbaric oxygen (HBO) has been used of neuropathic diseases, which can improve blood partial pressure of oxygen, reduce edema, relieve neural oppression and attenuate inflammatory response. The hypothesis of this protocol is that hyperbaric oxygen treatment could relieve neuropathic pain and improve the quality of life in TN patients. Visual analogue scale (VAS) and the mcgill pain questionnaire (MGPQ) will be assessed before the initiation of the study, after hyperbaric oxygen (HBO) treatment and at monthly intervals for the subsequent 3 months. Titration of dosage and pain frequency will be recorded throughout the study. Clinical global impression (CGI) by the individual patient will be evaluated at monthly intervals after HBO treatment.
