摘　　要：目的探究猪经胸超声心动图(transthoracic echocardiography,TTE)监测模型的建立及常用切面的获取方法。方法挑选10只体格正常的健康小猪,12~18个月,体重45~60 kg。采用Philips CX-50超声系统和TTE探头进行TTE相关操作。在全身麻醉状态下,连续两次记录5个TTE常用切面[胸骨旁左室长轴切面(parasternal long-axis view,PLAX)、胸骨旁短轴切面(parasternal short-axis view,PSAX)、心尖部四腔心切面(apical 4-chamber view,A4C)、剑突下四腔心切面(subcostal 4-chamber view,S4C)、剑突下下腔静脉长轴切面(subcostal inferior vena cava long-axis view,SILAX)]的获取情况,并用Kappa检验分析获取情况的一致性。结果PLAX两次获取率均为100%,提示两次切面获取一致性较好(Kappa=1);PSAX两次获取率均为90%,提示两次切面获取一致性较好(Kappa=1);A4C两次获取率分别为80%、70%,提示两次切面获取一致性一般(Kappa=0.61);S4C两次获取率均为90%,提示两次切面获取一致性较好(Kappa=1);SILAX两次获取率分别为80%、90%,提示两次切面获取一致性一般(Kappa=0.62)。结论将TTE探头置于猪相应体表标志处可以稳定获取TTE常用切面。Objective To explore the establishment of a pig monitoring model for transthoracic echocardiography(TTE)and the acquisition method of commonly used sections.Methods Ten physically normal pigs,weighing 45-60 kg,aged 12-18 months,were selected in the current study.The Philips CX-50 ultrasonic system and TTE probe are used for TTE related operations.Five commonly used sections were recorded for consecutively twice consecutively under general anesthesia,including the parasternal long-axis view(PLAX),the parasternal short-axis view(PSAX),the apical 4-chamber view(A4C),the subcostal 4-chamber view(S4C)and the subcostal inferior vena cava long-axis view(SILAX),and use Kappa test to analyze the consistency of the acquisition.Results The conditions of the five commonly used TTE sections were showed as follows:the two acquisition rates of the parasternal long axis view were both 100%,suggesting that the two acquisitions had a good consistency(Kappa=1).The two acquisition rates of the parasternal short-axis view were both 90%,suggesting that the two acquisitions had a good consistency(Kappa=1).The two acquisition rates of the apical 4-chamber view were 80%and 70%respectively,suggesting that the two acquisitions had a common consistency(Kappa=0.61).The two acquisition rates of the subcostal 4-chamber view were both 90%,suggesting that the two acquisitions had a good consistency(Kappa=1).The two acquisition rates of the subcostal IVC long-axis view were 80%and 90 respectively,suggesting that the two acquisitions had a common consistency(Kappa=0.62).Conclusion The operation method that the TTE probe is placed on the corresponding body surface marker of the pig can stably obtain the commonly used sections of TTE.
