ABSTRACT
Objective To introduce extrapedicular infiltration anesthesia as an improved method of local anesthesia which applied to unipedicular percutaneous vertebroplasty or percutaneous kyphoplasty.Methods From March 2015 to March 2016,20 patients in our hospital received percutaneous vertebroplasty or percutaneous kyphoplasty with 1％ lidocaine local infiltration anesthesia and extrapedicular infiltration anesthesia.The visual analogue score of patients during the operation and whether they needed additional sedative anesthesia were evaluated.The anaesthetic effect of nerve root block was observed.Results The visual analogue score of all the patients ranged from 1 point to 3 point,averagely (2.5 ± 0.7) point.Among the 20 patients,there were 2 cases of 1 point,7 cases of 2 point and 11 cases of 3 point.No patients required additional sedative anesthesia,and no nerve root block effects were observed.Conclusion Extrapedicular infiltration anesthesia provides good local anesthetic effects without significant complications,which deserved further use in unipedicular percutaneous vertebroplasty and percutaneous kyphoplasty.
ABSTRACT
The aim of this study was to evaluate the influence of intraocular 1% lidocaine as an adjunct to topical anesthesia on corneal endothelial cell during phacoemulcification. We evaluated 38 patients(50 eyes). All patients underwent phacoemulsification and PCL implantaion. Twenty five eyes were used intraocular 1% lidocaine and topical anesthesia and others used only topical anesthesia. Endothelial cell density was examind preoperatively, and at 1 day, 1 week, 1 and 2 months postoperatively by specular microscopy. The difference of preoperative endothelial cell density between two groups was not statistically significant. In lidocaine-used group, the average endothelial cell loss was 7. 6%, 9. 2%, 10.4%, 10.6%at 1 day, 1 week, 1 and 2 months. In non used group, the average endothelial cell loss was 7. 4%, 9. 4%, 9. 9%, 11. 7%at 1 day, 1 week, 1 and 2 months. The difference of postoperative endothelial cell density between two groups was not statistically significant(P>0.1). From these results, we conclude that the intraocular lidocaine infusion for anesthesia had little effect on the corneal endothelial cell loss.
