毒鼠强浓度在人体内变化规律研究

Objective To study the variation of blood concentration of tetramine in human body with acute tetramine intoxication treated with three different protocols and the levels in human body after discharge from the hos-pital. Methods The blood concentration of tetramine was determined by gas chromatography-mass spectrometry (GC-MS). All 101 patients of acute tetramine intoxication were divided into 3 groups (routine comprehensive treat-ment group,hemoperfusion group,blood transfusion group) according to their blood concentration of tetramine and clinical symptoms. The patients were followed up to monitor the tetramine levels in a year. Results The level of tet-famine in blood was decreased from 33.0(1.7～115.0)μg/L to 18.0(0.3～47.6)μg/L in routine comprehensive treatment group. The total decrement was 45.5 %. The level was decreased from 108.0 (54.0～290.0)μg/L to 26.0 μg/L in hemoperfusion group. The total decrement was 75.9%. The decrement was 20.0%～45.0% after each he-moperfusion. The level was slightly high after 24 h of hemoperfusion. The total decrement in blood transfusion group was 33.5%～60.0%. The level was <0.3μg/L in all 25 out-patients 1 year after their intoxication. Conclusion Routine comprehensive treatment,hemoperfusion,blood transfusion are effective in the treatment of acute tetramine intoxication. The degradation of tetramine in human body is slow.     

小儿静脉输液拔针后的护患交流小技巧

静脉输液完毕后拔针是一项重要的环节，尤其是小儿患者，拔针时由于恐惧和疼痛，易哭闹不安和不配合；如果拔针后交待不到位，还可能导致某些并发症，如穿刺部位出血、皮下出血或轻度的皮肤损伤，给患者造成不必要的痛苦，并留下护理纠纷的隐患。为此，我们总结了一些输液完毕后的护患沟通技巧，在临床护理中取得了良好的效果：（1）拔针前告知患儿家长，患儿会因为恐惧、疼痛造成哭闹不止，为防止针孔及皮下出血，一定要按血管走行方向压紧棉球，勿松手；（2）拔针前嘱患儿家长协助固定患儿穿刺部位的肢体或头部，防止护士拔针时因为患儿活动而使针头移位，造成不必要的皮肤损伤；（3）按压时不能揉，防止造成皮下出血；（4）按压时间要相对较长，防止针眼再次出血而造成不必要的恐惧及麻烦。
