Treatment of acute heart failure with conventional ltherapy and bi-level positive airway pressure / 中国基层医药

Objective To evaluate the therapeutic effects of bi-level positive airway pressure on acute left heart failure. Methods Thirty patients with acute left heart failure received combined conventional therapy and bilevel positive airway pressure, and were compared with 30 patients with acute left heart failure receiving traditional treatment as controls. The changes in the power of hydrogen, partial pressure of oxygen in artery, pulse oxygen saturation,partial pressure of carbondioxide in artery,buffuer excess,blood pressure,heart rate,and breathing frequency,and clinical symptom were compared between the two groups. Results Compared with control group,the blood pressure,heart rate, breathing frequency decreased significantly( P＜0. 05 ) ;pulse oxygen saturation increased significantly (P＜0. 05 ) ; the power of hydrogen, partial pressure of oxygen in artery, partial pressure of carbondioxide in artery, and buffuer excess were improved more significantly ( P＜0. 05 ) ; the marked response rate and the total effective rate increased significantly(P＜0. 05). Conclusion The combined conventional therapy and bi-level positive airway pressure has a good efficacy in the patients with acute left heart failure.

Cleaning Effect of Multi-enzyme Agent / 中华医院感染学杂志

OBJECTIVE To evaluate the medical instrument′s cleaning effect and bacterial elimination result by using multi-enzyme cleaning agent.METHODS The total 229 pieces of moderate contaminated medical instrument were randomly divided into 2 groups:control group and experiment group.The effects after routine water immersion and processing of multi-enzyme cleaning(including hand cleaning and machineone were observed and the bacteriological examination in the sample was checked.RESULTS 96% of the medical instruments in experiment group were cleaned,while only 35% of them in control group were cleaned.It was showed the cleaning effect of multi-enzyme was better than routine water immersion.In the experiment group,the contaminated rates of blood pincers and tweezers after hand cleaning with multi-enzyme were 33.7% and 25.5%,respectively,while the contaminated rates of blood pincers and tweezers after machine cleaning with multi-enzyme were 0.It indicated that the bacterial eliminate rate of machine cleaning with multi-enzyme was higher than hand cleaning with multi-enzyme.CONCLUSIONS Multi-enzyme agents are better for medical instrument cleaning.
