Abstract: 【Abstract】....Objective...To discuss the role of the mean arterial pressure (MAP) and pulse pressure (PP) in early assessment on vascular crisis after wrist replantation. Methods〓A retrospective clinical data were analyzed in 8 cases from August 2014 to November 2015, who suffered from vessel crisis after wrist replantation (observation group), and 10 cases with stable vital signs in ICU as control group. Both groups received continuous brachial arterial pressure. MAP and PP were recorded at 2 h, 1 h, and 0.5 h before vessel crisis happened. All cases with vascular crisis were confirmed by digital subtraction angiography (DSA). Results〓All 8 cases with vessel crisis were handled in time and performed extremities survived after surgery. The values of MAP and PP (mmHg) recorded at 2 h,1 h,0.5 h were 70.13±4.86 and 46.88±4.84,62.00±4.48 and 51.88±4.27,66.25±1.51 and 66.13±1.16, respectively. The values of MAP and PP (mmHg) in control group were 72.5±3.3,46.4±2.8. However, only the value of PP at 0.5 h showed the significant statistical significance. Conclusion〓PP may be as an early predictor of vascular crisis after wrist replantation. However, the samples in this study was limited, as well as the measuring method of MAP and the design, which should be improved.
