【摘要】：目的:探討拇指血流灌注指數(shù)(Perfusion Index,PI)試驗替代改良Allen試驗(modified Allen's test,MAT)評價掌部組織側(cè)支循環(huán)血流灌注的可行性。方法:選擇1108例擬行擇期手術(shù)并需要經(jīng)橈動脈入路進行有創(chuàng)動脈壓力監(jiān)測的患者,在橈動脈穿刺前先后用MAT和拇指PI值試驗分別評價患者試驗側(cè)掌部組織側(cè)支循環(huán)血流灌注的情況,并將兩種試驗方法結(jié)果進行統(tǒng)計學(xué)比較和分析。結(jié)果:在1108例患者中MAT陰性患者1035例(93.41%),陽性患者73例(6.59%);拇指PI值試驗陰性患者1090例(98.38%),其中包括57例MAT陽性患者,陽性患者18例(1.62%)。拇指PI值試驗陰性患者行經(jīng)該側(cè)橈動脈入路進行有創(chuàng)動脈壓力監(jiān)測,兩種試驗方法結(jié)果進行卡方檢驗,差異有統(tǒng)計學(xué)意義(x2=51.27,P0.05)。兩種試驗方法影響因素進行l(wèi)ogistic回歸分析發(fā)現(xiàn)兩種試驗方法結(jié)果陽性率均與年齡和性別有相關(guān)性(P0.05)。結(jié)論:在本研究中用拇指PI值試驗篩選出1.62%的患者不宜行經(jīng)橈動脈入路進行有創(chuàng)動脈壓力監(jiān)測。拇指PI值試驗的敏感性高于MAT,并且拇指PI值試驗方法簡單、操作方便,值得在臨床工作中推廣,用于替代MAT來評價掌部組織側(cè)支循環(huán)血流灌注的情況。
[Abstract]:Objective: to evaluate the feasibility of thumb perfusion index (Pi) test in evaluating collateral circulation perfusion in palmar tissues in place of modified Allen test and modified Allen's test. Methods: 1108 patients with invasive arterial pressure monitoring were selected. Before radial artery puncture, MAT and thumb Pi test were used to evaluate the collateral circulation perfusion in the palmar tissue of the patients, and the results of the two methods were compared and analyzed statistically. Results: of the 1108 cases, 1035 cases were MAT negative, 73 cases were positive, 1090 cases were negative for thumb Pi test, including 57 cases were MAT positive, 18 cases were positive. The invasive arterial pressure was monitored through the radial artery approach in patients with negative Pi test of thumb. The results of the two test methods were chi-square test. The difference was statistically significant (P 0.05). Logistic regression analysis showed that the positive rate of the two test methods was correlated with age and sex (P 0.05). Conclusion: in this study, 1.62% of the patients were selected by thumb Pi test for invasive arterial pressure monitoring via radial artery approach. The sensitivity of Pi value test of thumb is higher than that of MATT, and the method of thumb Pi value test is simple and easy to operate, which is worth popularizing in clinical work. It can be used to evaluate collateral circulation perfusion in palmar tissue instead of MAT.
