Abstract

Pulmonary extravascular thermal volume (PETV) was measured during pulmonary artery occlusion in 18 patients preoperatively and 7 patients postoperatively who were undergoing pneumonectomy. We found that the PETV decreased from 6.6±2.3 ml·kg before occlusion to 4.1±1.6 ml·kg during occlusion. There was a significant correlation between the PETVs before and during occlusion multiplied by the fraction of pulmonary perfusion (r=0.77,P<0.001). Although the PETV increased in two patients and decreased in four within 48 h after pneumonectomy, it returned to the value during occlusion at 3 weeks after pneumonectomy in seven patients. There was a significant correlation between the PETV during occlusion and that at 3 weeks after pneumonectomy (r=0.66,P<0.05). In conclusion, PETV during pulmonary artery occlusion is a reliable baseline value in the assessment of postoperative pneumonectomy values.

摘要

在18例术前和7例术后接受肺切除术的患者肺动脉闭塞期间测量肺血管外热容积（PETV）。我们发现PETV在闭塞前为6.6±2.3 ml·kg，闭塞期间降至4.1±1.6 ml·kg。闭塞前和闭塞期间的PETV乘以肺灌注分数之间存在显著相关性（r=0.77，P< 0.001）。虽然有2例患者在肺切除术后48小时内PETV增加，4例患者PETV降低，但7例患者在肺切除术后3周时PETV恢复到闭塞期间的值。闭塞期间的PETV与肺切除术后3周时的PETV之间存在显著相关性（r=0.66，P< 0.05）。总之，肺动脉闭塞期间的PETV是评估肺切除术后值的可靠基线值。
