目的探讨同步观察脉搏指示连续心排出量(PiC CO)和连续腹内压监测技术在ICU危重患者中的联合应用,对二者的相关性进行分析。方法我院普外科ICU病房2014年1月至2015年6月收治并同时进行了PiC CO和腹内压实时监测的危重患者共8例,通过建立PiC CO监测通道以及腹腔内低顺应性毛细测压管,记录患者进入ICU病房3 d内每隔8 h同步监测PiC CO所测得的连续心排出量(PCCO)以及腹腔内直接测压法所测得的腹内压。结果 8例患者术后3 d内每8 h同步记录的PCCO及腹内压共72个记录点的数据进行排除患者因素的偏相关性分析,所得相关系数R=-0.682(P<0.001)。结论危重患者的腹内压与PCCO间存在显著的负相关性,同步监测有利于更全面地掌握患者病情,值得在临床中进一步应用和探索。
Objective To explore the combined application of simultaneous observation of pulse-induced continuous cardiac output (PiC CO) and continuous intra-abdominal pressure monitoring in critically ill patients with ICU, and to analyze their correlation. Methods A total of 8 critically ill patients admitted to our hospital from January 2014 to June 2015 with PiC CO and intra-abdominal real-time monitoring were enrolled in this study. The establishment of PiC CO monitoring channel and intraperitoneal low compliance capillary The patients were admitted to the ICU ward for recording the continuous cardiac output (PCCO) measured by PiC CO and the intra-abdominal pressure measured by intra-abdominal direct manometry every 8 hours. Results The partial correlation analysis of the patients with PCCO and the data of 72 intra-abdominal pressure recordings recorded every 8 hours within 3 days after operation in 8 patients was performed. The correlation coefficient R = -0.682 (P <0.001). Conclusions There is a significant negative correlation between intra-abdominal pressure and PCCO in critically ill patients. Simultaneous monitoring is more beneficial to grasp the patient’s condition more fully and is worth further clinical application.
