Abstract：

Objective To evaluate the value of noninvasive intermittent positive-pressure ventilation (NIPPV) in treatment of patients with pneumonoconiosis combined with respiratory failure. Method There were 46 inpatients with pneumonoconiosis combined with respiratory failure. Tetwenty-six inpatients treated with conventional therapy and NIPPV were categorized as treatment group; Tetwenty inpatients just treated by conventional therapy served as control group. Compared with the changes of HR、RR and arterial blood gas index (PH、PaCO2、PaO2) in two groups after treatment. Results The effective ratio of treatment group was 88.5%, control group was 60%, which had significant difference (P＜0.05); The HR in treatment group after treatment was(95.38±10.75)beats per minute, control group was [(103.00±12.56)beats per minute; The RR in treatment group was (21.69±1.37) breaths per minute, control group was [(22.60± 1.57)breaths per minute];The PaCO2 in treatment group was (52.88±10.75)mm Hg, control group was [(59.66± 11.49)mm Hg];All of those were significantly decreased than those in control group (P＜0.05). The PaO2 in treatment group was (100.77±25.3)mm Hg, control group was [(71.82±17.94) mmHg];Compared with the control group, PaO2 in the treatment group increased significantly (P＜0.05). Conclusion NIPPV is beneficial to pneumonoconiosis combined with respiratory failure in different degrees.     

亚低温治疗急性呼吸窘迫综合征患者对炎性反应影响及肺保护作用的研究

Objective To explore the effect of mild hypothermia on inflammation status,lung function protection and clinical prognosis in patients with acute respiratory distress syndrome (ARDS).Methods All of 56 patients with ARDS were randomly divided into two groups: trial group (29 patients,treatment with mild hypothermia) and control group (27 patients, treatment with common practice). The following parameters including tumor necrosis factor (TNF)-α,interleukin (IL)-6 and C reactive protein (CRP), oxygenation index, SOFA evaluation and injury of lungs evaluation were detemined before treatment and at the 3rd, 7th day after treatment, and survival rates and adverse reaction in 28 days also were observed.Results After treatment, the levels of TNF-α ,IL-6 and CRP were decreased significantly, and oxygenation index, the scores of SOFA evaluation and injury of lungs evaluation were improved significantly in trial group than those in control group (P<0.05 ). The survival rate in trial group was higher than that in control group after treatment of 28 days [65.5%(19/29) vs 51.9%(14/27)]. The courses of mechanical ventilation and staying in ICU in trial group were shorter than those in control group [(11.9±3.6)d vs (17.0±5.1)d,(14.1±4.2)d vs (21.5±7.7)d](P<0.05). Conclusion Mild hypothermia can effectively attenuate inflammation disorder, improve damaged lung function and prognosis in patients with ARDS.

等效镇痛剂量舒芬太尼和瑞芬太尼呼吸抑制作用的比较

Objective To observe the respiratory depression of sufentanil and remifentanil with target-controlled infusion under propofol sedation or not, and compare the effect of respiratory depression of the two drugs. Methods Eighty patients scheduled for elective neurosurgery were allocated into four groups by random digits table: the sufentanil group (group S), the remifentanil group (group R), the combination of sufentanil and propofol group (group SP) and the combination of remifentanil and propofol group (group RP),each group was 20 cases. The respiratory rate (RR), minute ventilation (MV),partial pressure of end-tidal carbondioxide ( PETCO2), pulse oxygen saturation (SpO2), mean arterial pressure ( MAP ), heart rate (HR), observer's assessment of alertness/sedation (OAA/S) were measured and respiratory depression was defined as one of the following end points were achieved: muscle rigidity, RR ＜ 6 beats/min, MV ＜ 3 L/min,PETCO2 ＞ 55 mm Hg ( 1 mm Hg = 0.133 kPa), SpO2 ＜ 0.90 or apnea ＞ 15 s. Results The calculated effect concentration (Ce) of sufentanil for respiratory depression were (0.46 ± 0.14) μ g/L in group S and (0.23 ±0.06) μ g/L in group SP, and Ce of remifentanil for respiratory depression were (5.22 ± 2.11 ) μ g/L in group R and (2.22 ± 1.02) μ g/L in group PP. Some respiratory parameters,such as RR,MV were decreased and PETCO2 was increased significantly as the increase of Ce. Conclusions Target-controlled infusion of equal analgesic plasma concentration of sufentanil and remifentanil can suppress spontaneous respiration significantly with the increase of plasma concentration. There will be a synergetic effect after combining with propofol, and respiratory depression will appear at lower concentration. But equal analgesic plasma concentration of the two drugs have no significant difference in the effect of respiratory depression.     

血液灌流结合连续性静脉-静脉血液滤过对急性百草枯中毒疗效的研究

Objective To explore the therapic effects of hemoperfusion (HP) with continuous venovenous hemofiltration (CVVH) on the patients with acute paraquat poisoning. Methods Nighty-one patients with acute paraquat poisoning were randomly divided into HP group (49 cases) and HP-CVVH group(42 cases). The mortality, survival duration and the death causes between the two groups were compared and analyzed. Results There were no significant differences in mortality (59.2% versus 61.9%) between the two groups. The mean time between poisoning and death in HP-CVVH group was (4.9±3.1) days, which was significantly longer than that (3.5 ±2.0) days in HP group (P＜0.05).The death proportion on 4th day after poisoning in HP group was 62.1%(18/29), which was significantly higher than that (30.8%, 8/26) in HPCVVH group (P＜0.05). The hypoxia appeared in 4.3±2.5 days after poisoning in HP-CVVH group, which was significantly longer than that (3.2±1.9) days in HP group (P＜0.05). The mortality due to respiratory failure in HP group was 20.4%(10/49),which was significantly lower than that (40.5%, 17/42) in HP-CVVH group (P＜0.05). The incidence of acute renal failure in HP group was 63.3%(31/49), which was significantly higher than that (40.5%,17/42) in HP-CVYH group (P＜0.05). Conclusion The combined therapy of HP and CVVH can prevent the patients with acute paraquat poisoning from early death and prolong the survival duration, but can not reduce mortality for the patients with acute paraquat poisoning.
