The purpose of this study is to assess the effect of hegu point massage with ice on intensity of sternotomy pain in patient post coronary artery bypass graft surgery. Design:This study is double blind, randomized control trial will perform on patients less than 75 years old, hospitalized in heart center of Mazandaran in 2015. 64 patients are chosen in accessible manner and randomly divided in two equal groups as experiment and control. Inclusion criteria in this study are; age lower than 75 years, not to have history of open heart surgery, ef≥35%. Exclusion criteria are sensivity to cold, peripheral vascular diseases, Connective tissue diseases, the need for intra- aortic pump, bleeding greater than 200cc from chest tube, repaire or exchange vale surgery with coronary artery bypass graft, addiction to alcohol and narcotics, Body mass Index greater than 30. Intervention: Visual analogue scale is used for Measurement of pain intensity. Intervention is conducted by one person and pain measuring is done by another person that don’t know patient’ group. Pain intensity is measured in two group before any intervention. Patient is located in semisitting or sitting position if possible and is wanted him, deep inspiration and then expiration compeletely. In experiment group massage is conducted with ice in sides 2×2 in left hand Hegu point with moderate pressure in total time 10 minute(2 minute massage and 15 second break). Pressure intensity is continued until nail whitening appear. If there is not administrated invariable analgesic protocol, we will delay intervention at least 4 hours after the last analgesic medicine. In control group glass ball with same sides and time is put in left hand hegu point without pressure and massage. pain intensity is measured immediately, 30minute, 60 minute and 120 minute by Visual Analogue Scale after intervention. Primary outcome variable is pain after cardiac surgery and secondry outcome variable is sesivity to cold.
