We studied the metabolic and hormonal responses of 30 elderly patients undergoing routine cataract surgery who were allocated randomly to receive either general anaesthesia, or local anaesthesia by means of either retrobulbar or peribulbar blockade. Both forms of local anaesthesia successfully prevented the increases in circulating cortisol and glucose concentrations seen in those patients who received general anaesthesia, there being no significant differences between retrobulbar and peribulbar blockade. The results show that the newer, and now more commonly performed peribulbar block, confers the same metabolic and hormonal stability as seen with the more traditional retrobulbar block.
我们研究了30例接受常规白内障手术的老年患者的代谢和激素反应，这些患者被随机分配接受全身麻醉，或通过球后阻滞或球周阻滞进行局部麻醉。两种局部麻醉方式均成功地防止了接受全身麻醉的患者出现循环皮质醇和血糖浓度升高的情况，球后阻滞和球周阻滞之间没有显著差异。结果表明，更新的、现在更常用的球周阻滞与更传统的球后阻滞具有相同的代谢和激素稳定性。
