Abstract：Objective To explore the effect of vibration sputum excretion with surface location combined with lung dilated suction in patients with mechanical ventilation in emergency.Methods Totally 86 patients receiving emergency mechanical ventilation from June 2009 to June 2013 were randomly divided into observation group and control group (43 cases in each group).Control group given conventional suction sputum,observation group were given vibration sputum excretion with surface location combined with lung dilated suction.The arterial oxygen saturation (SaO2),partial pressure of oxygen (PaO2),partial pressure of carbon dioxide (PaCO2),respiratory rate (RR) before and 5 days after suction sputum were recorded;the total amount of suction sputum,interval time of sputum suction,complete degree of suction complete degree and complications were compared between groups.Results The SaO2,PaCO2,PaO2,RR were not significantly different before suction;they were significantly improved after suction in control group [(93.2 ± 4.8) ％ vs (87.1 ± 6.8) ％,(121 ± 19) mmHg vs (97±19) mmHg,(40 ±6) mmHg vs (42 ± 12) mmHg,(25 ±5) times/min vs (29 ± 7)times/min] and observation group [(98.4 ±2.9) ％ vs (86.7 ±5.8) ％,(132±15) mmHg vs (97±18) mmHg,(38 ±4) mmHg vs (42 ± 10) mmHg,(22 ±3) times/min vs (29 ±7) times/min],and were more better in observation group (P ＜ 0.05).The suction amount in observation group were more on the 1 st-3rd day and were less on the 4th and 5th day compared with those in control group [(30.5 ±0.8) ml vs (20.5 ± 1.2) ml,(44.8±1.6) mlvs (31.6±1.5) ml,(36.2±1.9) mlvs (31.3±1.7) ml,(17.2±2.1) mlvs (28.4 ±0.9) ml,(10.3 ±0.9) ml vs (25.1 ± 1.3) ml] (P ＜0.05).The interval time of consecutive suction sputum in observation group was significantly longer than that in control group [(2.9 ± 0.7) h vs (1.3 ±1.0) h] (P ＜ 0.05).The complete degree of suction in observation group was higher than that in control group [(1.4 ± 0.5) scores vs (2.0 ± 0.4) scores] (P ＜ 0.05).The incidence of complication in observation group was significantly lower than that in control group [4.7％ (2/43) vs 18.6％ (8/43)] (P ＜ 0.05).Conclusion The effect of vibration sputum excretion with surface location combined with lung dilated suction is superior to conventional exhausting sputum method with good safety and is applicable to patients with emergency mechanical ventilation,especially for those with coma and cough asthenia.
