无创间歇正压通气治疗尘肺并发呼吸衰竭的疗效观察

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.
