TI  - Palmar microcirculation after harvesting of the radial artery in coronary 
      revascularization.
PG  - 1026-30; discussion 1030
AB  - PURPOSE: To evaluate real-time parameters of palmar microcirculation before and 
      after harvesting of the radial artery in coronary revascularization using a laser 
      Doppler flowmetry and remission spectroscopy system (O2C). DESCRIPTION: Fifteen 
      patients (11 males, 54 +/- 4 years, mean New York Heart Association [NYHA] class 
      of 2.3 +/- 0.3) were prospectively scheduled with control measurements of the 
      fingertips of D1, D3, and D5 at base line, after suprasystolic, and after 
      selective radial or ulnar compression for tissue oxygen saturation (SO2), 
      postcapillary venous recombinant hemoglobin (rHb) concentration, superficial (2 
      mm) blood flow, and deep (8 mm) blood flow. EVALUATION: Preoperatively during 
      suprasystolic compression SO2 decreased significantly for the fingertips of D1, 
      D3, and D5 by -58%, -74%, and -63%, respectively (p < 0.05). Radial compression 
      reduced SO2 for all fingertips (-12%, -14%, and -16%), as did ulnar compression 
      (-24%, -18%, and -10%). rHb did not change significantly for either compression 
      type. Superficial and deep blood flow decreased significantly after suprasystolic 
      and only slightly after radial and ulnar compression at either side. No side 
      differences were noted. After radial artery harvesting, microcirculatory 
      parameters did not change considerably versus preoperatively. CONCLUSIONS: Radial 
      artery harvesting does not remarkably change microcirculatory parameters of the 
      hand. The O2C system is a safe and quantitative method to assess both 
      preoperatively and postoperatively the palmar microcirculation and therefore adds 
      further functional clinical information.
