Effects of PiCCO and bedside dynamic ultrasound on severe pneumonia combined with ARDS-A comparative clinical study
Objective To explore the efficacy observation of pulse indicator continuous cardiac output monitoring(PiCCO)combined with ultrasound in fluid resuscitation of patients with severe pneumonia combined with ARDS.Methods Twenty patients with severe pneumonia combined with Acute Respiratory Distress Syndrome(ARDS)were selected as the study subjects(Group A),and PiCCO was used to dynamically monitor the whole-heart ejection fraction(GEF),whole-heart end-diastolic volume(GEDV),in-trathoracic blood volume(ITBV),extravascular lung water index(EVLW),etc.In the control group(Group B),20 patients with recent severe pneumonia combined with ARDS were monitored by bedside ultrasound for left ventricular end-diastolic volume(LVEDV),ve-locity time integral(VTI),left ventricular volume per beat(SV),and cardiac output index(CI),etc.In both groups,physiological inde-xes,blood lactate(Lac),oxygenation index(PaO2/FiO2)as well as mean arterial pressure(MAP)and fluid volume were closely moni-tored at the time of admission to evaluate the prognosis of the patients.Results Hemodynamic indexes such as CI,GEDVI,ITBVI,EVL-WI improved significantly after treatment in group A,and SV,LVEDV also improved after treatment in group B(P<0.05).The duration of mechanical ventilation and ICU hospitalization was significantly lower in group A than in group B(P<0.05).The difference in mor-bidity and mortality rates between the two groups was not statistically significant(P>0.05).Conclusion The patients with severe pneumonia combined with ARDS are monitored by PiCCO technology,and the guided treatment could significantly shorten the patients'mechanical ventilation time and ICU treatment time compared with bedside ultrasound.
