Randomized Controlled Trial Comparative StudySub-Tenon's block in cataract surgery--a comparison of 1% ropivacaine and a mixture of 2% lignocaine and 0.5% bupivacaine.
Sub-Tenon's block for cataract surgery is an increasingly common technique. While this technique has been successfully applied, the optimal local anaesthetic solution is not known. This study was performed to assess any differences in anaesthesia and oculomotor block between 1% ropivacaine and a 2% lignocaine with 0.5% bupivacaine mixture. The results indicate that there was no difference noted in the clinical effect between the solutions.

Erythropoietin is a glycoprotein hormone mainly released by the kidney, which stimulates red blood cell production. However, in sepsis, the mechanisms responsible for the final increase in circulating erythropoietin remain unclear Seventeen critically ill patients with Simplified Acute Physiologic Score average 66 (range 43 to 103) were included in this study. Ten patients survived and seven died within 28 days. ⋯ High serum erythropoietin levels in non-survivors were observed with septic shock despite an increase in the levels of proinflammatory cytokines. We found a relationship between erythropoietin concentration and biological markers of tissue hypoperfusion i.e. lactate levels or PCO2 gap. This relationship could suggest tissue hypoperfusion as the stimulating factor for erythropoietin production in septic shock.
