目的比较相同值的持续负压（CNEP）和呼气末正压（PEEP）对机械通气患者的血流动力学影响。方法对15例交通事故创伤后连续住院的患者，随机采用ZEEP、10 cmH2O的PEEP和10 cmH2O的CNEP，15例颅脑损伤患者行机械通气治疗，9例合并胸外伤，6例无肺损伤。CNEP获得了“雨披”。ResultsWe观察到显着增加CI CNEP期间，ZEEP和PEEP 10 cmH2O相比。相应地，与PEEP 10 cmH2O相比，CNEP期间的氧输送指数显著增加。相反，降低与CNEP，如果与PEEP相比，无论是在患者和无肺damage.ConclusionCNEP可以显着增加CI在机械通气患者的患者和无相关的肺损伤。
ObjectiveTo compare the haemodynamic effects of identical values of continuous negative external pressure (CNEP) and positive end-expiratory pressure (PEEP) in a group of mechanically ventilated patients.SettingGeneral ICU, Vicenza Hospital, Italy.Patients15 consecutive patients, admitted after road accident trauma.MethodsWe compared the haemodynamic effects of ZEEP, 10 cmH2O of PEEP, and 10 cmH2O CNEP, applied in random order, in 15 head trauma patients under going controlled mechanical ventilation; 9 had associated thoracic trauma, while 6 did not have lung involvement. CNEP was obtained with a “poncho”.ResultsWe observed a significant increase in CI during CNEP, compared with both ZEEP and PEEP 10 cmH2O. Accordingly the oxygen delivery index significantly increased during CNEP, compared with PEEP 10 cmH2O. Conversely,decreased with CNEP, if compared with PEEP, both in patients with and without lung damage.ConclusionCNEP can significantly increase CI in mechanically ventilated patients in patients with and without associated lung damage.
