We evaluated the effects of stellate ganglion block (SGB) on conjunctival oxygen tension, ocular surface temperature (n = 7) and intraocular pressure (n = 18) in patients with retinal vein occlusion and other retinopathy. The conjunctival oxygen tension (PcjO2) increased from 45.6 +/- 5.0 mmHg to 76.3 +/- 19.9 mmHg in 45 minutes by SGB and then gradually returned to the control level. PcjO2 120 minutes following SGB remained still at a higher level compared with the control value. Ocular surface temperature increased from 35.1 +/- 0.3 degrees C to 35.9 +/- 0.3 degrees C 25 minutes following SGB. Intraocular pressure decreased below the control level from 15 minutes to 120 minutes by SGB following an initial temporary increase. In conclusion, we have found that SGB does increase oxygen tension in ocular tissue and decrease IOP.
我们评估了星状神经节阻滞（SGB）对视网膜静脉阻塞和其他视网膜病变患者结膜氧分压、眼表温度（n = 7）和眼压（n = 18）的影响。通过SGB，结膜氧分压（PcjO2）在45分钟内从45.6±5.0 mmHg升至76.3±19.9 mmHg，随后逐渐恢复至对照水平。SGB后120分钟时，PcjO2仍维持在高于对照值的水平。SGB后25分钟，眼表温度从35.1±0.3℃升至35.9±0.3℃。在最初短暂升高后，通过SGB，眼压从15分钟至120分钟低于对照水平。总之，我们发现SGB确实会增加眼组织中的氧分压并降低眼压。
