Abstract

ObjectiveThis study aimed to investigate the influence of injection rates of calibrating standard solution on monitoring pulse indicator continuous cardiac output (PICCO, made in Germany), and thereby to provide significant references for clinical practice.MethodsA total of 108 critical patients in stroke intensive care unit were identified. All these participants received transesophageal cardiac color Doppler ultrasound, and within 15 min PICCO equipment was utilized to monitor the relevant parameters, by means of 0 °C calibrating standard solution, and the injection speeds were 2–4, 5–7, and 8–10 s. Besides, the monitoring indicators were as follows, cardiac index, global ejection fraction, global end diastolic volume index. The potential correlations were evaluated between PICCO and transesophageal cardiac color Doppler ultrasound.ResultsAll the data was available, and the monitored parameters of PICOO at 2–4, 5–7, and 8–10 s were positively correlated with the parameters obtained from transesophageal cardiac color Doppler ultrasound (P < 0.05). Specially, it is worth emphasizing that the best correlation between them could be provided when the injection rate was 2–4 s.ConclusionWhen the injection rate at 2–4 s, the parameters obtained by PICOO were much closer to that of transesophageal cardiac color Doppler ultrasound. Furthermore, the parameters of PICOO obtained at 2–4 s could better reflect cardiac function of patients.

Highlights

Being regarded as a novel combination technology in medical domain, and one less invasive thermodilution-based technique, pulse indicator continuous cardiac output (PICCO) equipment could supervise pulse indicator continuous cardiac output, and monitor lung temperature dilution cardiac output [1,2,3,4]
Whole body ejection fraction (GEF), systemic end‐diastolic volume (GEDI), cardiac index (CI) As shown in Table 2, the data obtained from 2 to 4 s was highly consistent with the results provided by ultrasonography
Correlation analysis between transesophageal heart color ultrasound monitor and PICCO parameters As shown in Fig. 1, the PICCO parameters gained at the drip speed of 2–4 s were positively correlated with the results provided by transesophageal cardiac color Doppler ultrasound, and the correlation coefficient appeared much higher when compared with the data obtained at the injection speed of 5–7 s and 8–10 s

Summary

Introduction

Being regarded as a novel combination technology in medical domain, and one less invasive thermodilution-based technique, pulse indicator continuous cardiac output (PICCO) equipment could supervise pulse indicator continuous cardiac output, and monitor lung temperature dilution cardiac output [1,2,3,4]. This technology could be utilized to monitor the conventional hemodynamic parameters, in order to provide significant references for critically ill patients [2,3,4,5]. The PICCO monitor is an all-inclusive device, which provides a full picture of hemodynamic status
