【Abstract】 Objective To analyze the curative effect by aminophylline combined with non-invasive positive pressure ventilation in the treatment of chronic obstructive pulmonary disease (COPD) complicated with respiratory failure. Methods A total of 88 patients of chronic obstructive pulmonary disease complicated with respiratory failure were divided by computer randomization into control group and observation group, with 44 cases in each group. The control group received non-invasive positive pressure ventilation, and the observation group received aminophylline combined with non-invasive positive pressure ventilation. Clinical effects and adverse drug reactions of the two groups were compared. Results Before treatment, the differences of pulmonary function indications (proportion of forced expiratory volume in one second in forced vital capacity, residual volume/total lung capacity, and carbon monoxide diffusion capacity) and arterial blood gas results (pH, artery blood oxygen partial pressure, partial pressure of carbon dioxide, and oxyhemoglobin saturation) between the two groups had no statistical significance (P>0.05). After treatment, the observation group had much better residual volume/total lung capacity, carbon monoxide diffusion capacity, and arterial blood gas results than the control group. Their difference had statistical significance (P<0.05), while the difference of proportion of forced expiratory volume in one second in forced vital capacity was not statistically significant between the two groups (P>0.05). The difference of incidence of adverse reactions between the two groups had no statistical significance (P>0.05). Conclusion Combination of non-invasive positive pressure ventilation and aminophylline can provide precise effect in treating chronic obstructive pulmonary disease complicated with respiratory failure, and it is better than non-invasive positive pressure ventilation single treatment. This method has the advantages of safe and efficient with few adverse reactions, and it is worthy of further clinical promotion and application. 【Key words】 Non-invasive positive pressure ventilation; Aminophylline; Chronic obstructive pulmonary disease; Respiratory failure; Clinical effect
慢性阻塞性肺疾。–OPD)是呼吸內(nèi)科最常見的疾病之一, COPD是一種破壞性的肺部疾病, 是以不完全可逆的氣流受限為特征的疾病, 氣流受限通常呈進行性發(fā)展并與肺對有害顆;驓怏w的異常炎癥反應(yīng)有關(guān), 嚴重影響患者的生活質(zhì)量[1, 2]。該病患者多處于穩(wěn)定期, 但是, 由于感染等會加重患者的病情, 嚴重者甚至出現(xiàn)呼吸衰竭, 嚴重威脅患者的生命安全[3, 4]。為此, 學(xué)者們和呼吸內(nèi)科臨床醫(yī)師一直致力于優(yōu)化COPD合并呼吸衰竭患者治療方案。本次作者采用無創(chuàng)正壓通氣聯(lián)合氨茶堿治療本院2012年8月~2014年8月呼吸內(nèi)科收治的慢性阻塞性肺疾病合并呼吸衰竭患者, 取得滿意的效果, 現(xiàn)將研究結(jié)果報告如下。
1 資料與方法
1. 1 一般資料 觀察對象來自2012年8月~2014年8月本院呼吸內(nèi)科收治的88例慢性阻塞性肺疾病合并呼吸衰竭患者。本研究入組患者均滿足以下標準:患者動脈血氣血氧分壓<60 mm Hg(1 mm Hg=0.133 kPa)和(或)二氧化碳分壓>50 mm Hg。運用計算機隨機分組的方式將慢性阻塞性肺疾病合并呼吸衰竭患者分為對照組和觀察組, 各44例。對照組男21例, 女23例, 年齡54~75歲, 平均年齡(65.78±5.63)歲;病程2~10年, 平均病程 (7.65±2.58)年;觀察組中男23例, 女21例, 年齡55~75歲, 平均年齡(66.12±5.79)歲;病程2~11年, 平均病程(7.44±2.01)年。兩組患者在性別構(gòu)成、平均年齡和平均病程等一般資料方面組間比較, 差異無統(tǒng)計學(xué)意義(P>0.05), 具有可比性。
1. 2 治療方法 對照組患者給予無創(chuàng)正壓通氣, 在為患者進行無創(chuàng)通氣前設(shè)置好呼吸機的呼吸模式(S/T):呼吸頻率設(shè)置在12~16次/min, 吸氣壓力設(shè)置在10~18 cm H2O(1 cm H2O= 0.098 kPa), 呼氣相壓力設(shè)置在4~8 cm H2O, 氧流量設(shè)置在2~5 L/min, 根據(jù)每位患者SaO2調(diào)整上述指標, 將SaO2控制在90%以上, 每位患者通氣時間2~4 h/次, 聯(lián)用7 d。觀察組患者則給予無創(chuàng)正壓通氣聯(lián)合氨茶堿(氨茶堿注射液250 mg加入5%葡萄糖注射液250 ml進行靜脈滴注)治療, 2次/d。
