Application of micro transesophageal echocardiography (micro-TEE) in neonat and infant cardiac surgery

Abstract

Objective To evaluate the value of phased array probe of transesophageal echocardiography miniature (micro-TEE) in the neonatal and infant cardiac surgery intraoperation. Methods Micro-TEE probe was used in children with weight ≤5 kg undergoing cardiac surgery to detect the atrial and ventricular cavity size, the left and right ventricular outflow tract diameter were detected by transthoracic echocardiography(TTE) 3-7 d after operation, and compared with the measured value immediately after the TEE. Results Before and after intubation, airway index not statistically significant (P>0.05). Preoperative TEE and TTE inspection results were consistent with intraoperative diagnosis. Postoperative TEE measuring intracardiac structural data (each room, chamber size and left and right ventricular outflow tract diameter) and postoperative TTE measurement value representing the difference was not statistically significant(P>0.05). Conclusions Micro TEE intraoperative guardianship of low birth weight infants is safe and feasible, and can supplement and improve the preoperative diagnosis, and can accurately and timely evaluate postoperative curative effect.
