ObjectiveTo evaluate the application value and significance of pulse indicator continuous cardiac output (PiCCO) in perioperative treatment of adult congenital heart disease (ACHD). MethodsBetween June 2014 and June 2015, 100 adult patients (44 females and 56 males) underwent congenital heart disease operation. Patients were randomly divided into a PiCCO group and an experience treatment (control) group. According to the data of PiCCO detection, the PiCCO group was treated with vasoactive drugs and liquid balance management, the control group was treated by routine monitoring data. The clinical effectiveness of the two groups was compared. ResultsThe ventilator time, ICU time and length of stay in the PiCCO group were significantly shorter than those in the control group with statistical differences (P=0.02, 0.03, 0.04). The drug dosage (dopamine, milrinone) during ICU were higher in the PiCCO group than those in the control group (P<0.01, P=0.04). There was no mortality in both groups. No significant difference was found in the incidence of postoperative complications between the two groups (P>0.05). ConclusionThe application of PiCCO in the perioperative treatment of adult congenital heart disease can promote the early recovery of ACHD patients, and has a certain safety and effectiveness. Actively vasoactive drugs application to maintain circulation early in ICU has positive effect on the patient's recovery.
