目的:調查手術室實施持續質量改進(continuous quality improvement,CQI)對手術室護理工作質量、工作效率和醫生、患者滿意度的影響。方法:成立科室質量控制小組,全科護理人員均為責任人。根據手術室質量管理中存在的問題確立改進目標,實施CQI。質控小組定期監測及發放問卷調查并比較實施CQI前后手術室工作質量、工作效率及醫生和患者的滿意度。結果:實施CQI后,手術室的術前用藥準備、術前平面清潔、術后整理、藥品按序擺放、物品定位放置、儀器完好、器械清洗合格各項指標均較實施CQI前改善;手術等待時間縮短,手術總臺次增加;醫生和患者的滿意度提高。結論:通過實施CQI,規范了護士的行為,提高了手術室的工作質量和工作效率,增加了醫生和患者的滿意度。
Objective To investigate the effects of different inspiratory rise time during noninvasive positive pressure ventilation ( NPPV) on work of breathing in patients with acute exacerbation of chronic obstructive pulmonary disease ( COPD) . Methods Eleven patients with acute exacerbation of COPD received different inspiratory rise time ( 0. 1sec, 0. 3sec, 0. 5sec) during NPPV. The changes of inspiratory muscle effort and breathing pattern of the patients were observed. Results The average respiratory rate,minute ventilation, and tidal volume were higher during NPPV compared with spontaneous breathing. But the changes of average minute ventilation and tidal volume were not significant ( P gt; 0. 05) . The pressure time product ( PTP) , transdiaphragmatic pressure ( Pdi) , and work of breathing of inspiratory muscle reduced significantly during different inspiratory rise time as compared with spontaneous breathing ( P lt;0. 01) . PTP,Pdi, and work of breathing reduced 59. 2% , 62. 7% , and 49% respectively when inspiratory rise time was 0. 1sec. They reduced more significantly during inspiratory rise time of 0. 1sec. Conclusions The present study confirms NPPV can unload inspiratory muscles in patients with acute exacerbation of COPD. It is more effective to reduce inspiratory load when inspiratory rise time is set at 0. 1sec while the patients feel most comfortable.
ObjectiveTo analyze the benefits of lung transplantation in the treatment of interstitial lung disease (ILD) and investigate its prognostic factors.MethodsThe clinical data of patients diagnosed with ILD and meet the lung transplantation criteria were retrospectively analyzed from January 2012 to December 2017 in the First Affiliated Hospital of Guangzhou Medical University. A total of 111 patients, 88 males and 23 females, aged (58.3±11.4) years old, were divided into lung transplantation group and non-lung transplantation group. Clinical data and prognosis of the two groups were compared and the factors affecting the prognosis of lung transplantation were analyzed with relevant literatures. Results There were 56 patients in lung transplantation group and 55 patients in non-lung transplantation group. The mainly underlying disease of both groups were idiopathic pulmonary fibrosis (IPF). There was no significant difference in age, body mass index, arterial partial pressure of oxygen, percentage of forced vital capacity in the estimated value, percentage of diffusing capacity of the lung for carbon monoxide in the estimated value, six-minute walk distance between the two groups (P>0.05). The pulmonary arterial hypertension and arterial partial pressure of carbondioxide were higher in lung transplantation group than non-transplantation group (P<0.05). The 1-year survival rate in the lung transplantation group was significantly higher than that in the non-lung transplantation group: 77.4% vs. 32.7% (P<0.01). COX regression analysis showed that preoperative ventilator dependence, serum creatinine, bilirubin, pulmonary artery pressure, and procedures (single lung vs. double lung) had no significant effect on the prognosis of lung transplantation; age and preoperative diabetes mellitus were risk factors for the prognosis of lung transplantation.ConclusionsLung transplantation can significantly improve the prognosis of patients with ILD who are refractory to medicine therapy. IPF patients should be advised to consider lung transplantation as soon as possible. Age and preoperative diabetes mellitus are risk factors for the prognosis of lung transplantation.
