Abstract

Introduction: Venovenous artificial placenta (VVAP) may mimic the intrauterine environment for maintaining fetal circulation. However, changes in ventricular function in fetal goats undergoing VVAP support remain unclear.

Methods: Pump-assisted VVAPs were established in five fetal goats for 9 h. The myocardial performance index (Tei index), cardiac output (CO), and blood biochemical parameters were measured during VVAP support.

Results: An increasing trend of the right ventricular (RV) Tei index was seen during VVAP support (p for trend < 0.01). The right ventricular cardiac output (RVCO) increased after the initiation of VVAP, while a significant trend of reduction was observed after 3 h (p for trend = 0.03). During VVAP support, we observed remarkable elevations of plasma cTnI and arterial lactic acid, which were positively correlated with the RV Tei index, but not the left ventricular (LV) Tei index, LVCO, and RVCO.

Conclusions: The RVCO increases initially while a tendency of decrease could be observed during VVAP support. Special attention should be paid to right ventricular dysfunction during VVAP support.

胎儿山羊静脉人工胎盘支持过程中心脏功能的改变。

导言：静脉人工胎盘（VVAP）可模拟宫内环境以维持胎儿循环。然而，接受 VVAP 支持的胎儿山羊心室功能的变化仍不清楚：在 VVAP 支持期间测量了心肌性能指数（Tei 指数）、心输出量（CO）和血液生化指标：结果：在 VVAP 支持期间，右心室 Tei 指数呈上升趋势（p for trend p for trend = 0.03）。在 VVAP 支持期间，我们观察到血浆 cTnI 和动脉乳酸显著升高，这与 RV Tei 指数呈正相关，但与左心室 Tei 指数、LVCO 和 RVCO 无关：结论：在 VVAP 支持期间，RVCO 最初会增加，但随后会呈下降趋势。结论：在 VVAP 支持过程中，RVCO 最初会增加，但随后会呈下降趋势。在 VVAP 支持过程中，应特别注意右心室功能障碍。
