抽象的
慢性阻塞性肺病(COPD)急性加剧患者并不总是易于施用的非侵入性压力支持通气(NIPSV)。当前,护士所花费的援助时间在急性发作(58名患者,I组)或后延伸高速呼吸资料(42名患者,II款患者))在医学密集的护理单位。在注册后的前24小时内,NIPSV在I组中使用6.7 +/- 3.2小时(平均+/- SD),第II组中的5.6 +/- 3.1小时;NIPSV会话的持续时间和每次会话的护士时间消耗量分别为47 +/- 12和11 +/- 7分钟,在II组中46 +/- 12和11 +/-6分钟。After the first 24 h of the study, the duration of NIPSV was 4.7+/-3.2 h x day(-1) in group I and 4.9+/-3.5 h x day(-1) in group II, and the nurse time consumption dropped significantly: the duration of NIPSV sessions and the nurse time consumption per session were respectively 44+/-10 and 7+/-4 min in group I, and 47+/-14 and 7+/-3 min in group II. Between the first 24 h and the subsequent period of 24 h, the nursing time dropped significantly (98 versus 59 min in group I (p<0.05), and 85 versus 52 min in group II (p<0.05)). There was no difference in the duration of NIPSV sessions, or in the overall assistance time per session, between the two groups of patients. In conclusion, the study seems to favour a quite low assistance time spent by nurses in relation to ventilatory time when noninvasive pressure support ventilation is used in chronic obstructive pulmonary disease patients with either acute exacerbations or postextubation hypercapnic respiratory insufficiency.
