| Sumario: | Hao Tang, Dong Liu, Yong Guo, Huayu Zhang, Yang Li, Xiaoyu Peng, Yaoli Wang, Dongpo Jiang, Lianyang Zhang, Zhengguo Wang Wound Trauma Medical Center, State Key Laboratory of Trauma, Burns and Combined Injury, Daping Hospital, Army Medical University, Chongqing, 400042, People’s Republic of ChinaCorrespondence: Zhengguo Wang; Lianyang Zhang Email hpzhangly@163.com; dpzhangly@163.comObjective: This study is the largest clinical study of noninvasive Abdominal wall tension (AWT) measurement with a tensiometer to date. It also initially applies a polynomial regression equation to analyze the correlation between AWT measurement and intravesical pressure (IVP) measurement and remarkably finds interesting changes between different IVP intervals and AWT.Methods: Critically ill patients who were treated in the intensive care unit (ICU) of Daping Hospital, Army Medical University, from August 30, 2018, to June 30, 2020, and met the inclusion criteria were prospectively included in this study. The patients were divided into an intra-abdominal hypertension group and a non-intra-abdominal hypertension group and an abdominal infection group and no abdominal infection group. AWT and IVP were measured at 9 points on the abdominal wall on the first day after admission to the ICU. The correlations between AWTs and IVP were analyzed, and the role of AWT in the diagnosis of complications of abdominal infection and the prediction of adverse prognosis were analyzed.Results: A total of 127 patients were included. The average AWT and IVP were 2.77± 0.38 N/mm and 12.31± 7.01 mmHg, respectively, on the first day of admission. There was a positive correlation between AWT and IVP (correlation coefficient r = 0.706, p < 0.05). The polynomial regression model was AWT= -1.616× 10− 3 IVP2 +8.323× 10− 2 IVP+2.094. The cutoff value of the sensitivity and specificity of AWT for the diagnosis of abdominal infection was 2.57 N/mm. Furthermore, AWT = 2.57 N/mm had the best diagnostic efficiency, which was better than that of IAH and lactate.Conclusion: There was a correlation between AWT and IVP. AWT measurement was helpful in the diagnosis of IAH and abdominal infection complications and can therefore serve as a new method for the clinical diagnosis of IVP and abdominal infection.Keywords: intra-abdominal hypertension, abdominal wall tension, intra-abdominal pressure, abdominal compliance, abdominal infection |
