穿透性角膜移植联合瞳孔成形术的临床观察

目的观察穿透性角膜移植联合瞳孔成形术的效果。方法４８只眼行穿透性角膜移植术的同时对虹膜缺损进行修复，成形瞳孔。术后随访６～８９个月。结果植片透明者３８只眼（７９．２％），视力恢复０．１以上者３１只眼（６４．６％），瞳孔修复接近正常者４３只眼（８９．６％）。结论穿透性角膜移植联合瞳孔成形术，可减少术后并发症、改善植片的预后及视功能。对波及瞳孔的虹膜缺损，联合行瞳孔成形术效果较好。

Spinal cord stimulation in the treatment of failed back surgery syndrome

A significant number of patients undergoing lumbar spine surgery do not obtain pain relief. Such patients with chronic low back or lower extremity pain may be difficult to treat. A frequent component of therapy is the use of spinal cord stimulation to help control pain. With careful patient selection, many patients can achieve reasonable levels of pain relief. We review recent clinical reports, including prospective and randomized studies, that demonstrate up to three quarters of patients implanted with a spinal cord stimulator for the treatment of failed back surgery syndrome may benefit from its use. This technology must not be indiscriminately applied. Careful patient selection and a period of trial stimulation are vital to the successful use of spinal cord stimulation as treatment for chronic pain.     

新生儿窒息后血糖,血气,心肌酶活性测定及其相关因素分析

目的：探讨新生儿窒息后血糖，血气，心肌酶（谷草转氨酶，磷酸肌酸激酶及乳酸氢酶）的变化及其相关性。方法；血糖采用微量血糖仪测定，血气用足跟动脉化毛细血管法，心肌酶采用酶偶联连续监测，相关分析采用多元线性回归法。结果：低血糖８例，高血糖３例；３６例均存在着不同程度的低氧血症和混合性酸中毒；２２例心肌酶活性增高。血糖值与日龄呈负相关，与体温呈正相关，心肌酶活性男性高于女性，各酶之间有一定的相关性，但并非     

Do patients receive adequate pain control after discharge from the ED?

Studies on the effectiveness of pain management have uniformly concluded that health care providers underestimate or undertreat pain. In the emergency department (ED) in which this study was conducted, physicians receive formal didactic and bedside teaching on pain recognition and management in order to heighten the awareness of patient's need for pain control. The purpose of this study was to determine if this outpatient pain management of patients with acute, painful conditions is better than that reported in the medical literature. In this prospective study, 110 adult patients who had an acute, painful diagnosis were telephoned 48 hours after discharge from the ED and asked if they felt their pain at home was well controlled. Patient satisfaction with pain control was higher (91%) than that reported in the medical literature. Also, pain medication was provided more frequently by this study's ED (95%). Education on pain awareness and treatment is a way to improve pain management.
