Brief Summary:
The purpose of this study is to assess whether a large clinical trial testing the effect of RIPC on neurologic outcome in patients undergoing elective cervical decompression surge is warranted.

Condition or disease Intervention/treatment Phase
Cervical Compression Myelopathy Ischemia Reperfusion Injury Spinal Cord Injury Procedure: limb remote ischemic preconditioning (LRIPC) Phase 1 Phase 2

Detailed Description:
Spinal cord ischemia-reperfusion injury commonly contribute to perioperative morbidity and mortality after elective cervical decompression surgery.Remote ischemic preconditioning(RIPC)is a phenomenon whereby brief periods of ischemia followed by reperfusion in one organ provide system protection from prolonged ischemia.The hypothesis of this protocol is that limb ischemic preconditioning could reduces spinal cord ischemia-reperfusion injury induced by elective cervical decompression surgery.Serum s-100B and NSE concentration will be measured before and after induction ,and at 6 hours,1,3,5 and 7days after surgery.JOA scores in all the cases will be evaluated before operation and at 7days ,1,3,6 month after surgery.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 51 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: Effects of Remote Ischemic Preconditioning on Biochemical Markers and Neurological Outcomes in Patients Undergoing Elective Cervical Decompression Surgery
Study Start Date : September 2007
Actual Primary Completion Date : October 2008
Actual Study Completion Date : April 2009

Arm Intervention/treatment
Experimental: A,2, II Procedure: limb remote ischemic preconditioning (LRIPC)
LRIPC consists of three 5-min cycles of right upper limb ischemia induced by an automated cuff-inflator placed on the upper arm and inflated to 200 mmHg,with an intervening 5 min reperfusion during which the cuff is deflated.
Other Name: an automated cuff-inflator made in China

Primary Outcome Measures :
  1. serum concentrations of s-100B,NSE [ Time Frame: 1 week or more ]

Secondary Outcome Measures :
  1. a Japanese Orthopaedic Association (JOA) scale [ Time Frame: 6 months ]
