Clinical study of basal blood pressure levels and different blood pressure control strategies with prognosis in patients with hemorrhage / 中国医师进修杂志

ABSTRACT

Objecitve To explore the relationship between basal blood pressure levels and prognosis in patients with hemorrhage,and the influence of different blood pressure control strategies in hematoma expansion and bleeding again.Methods Research methods for group-control,46 patients with hemorrhage from January 2010 to January 2013 according to the basal blood pressure levels (systolic blood pressure) in the first day of admission were divided into group A (＜ 180 mmHg,1 mmHg =0.133 kPa) 7 cases,group B (180-200 mmHg) 6 cases and group C (＞200 mmHg) 33 cases.At the same time according to different blood pressure control strategies were divided into group E (mean arterial pressure decreased ≥ 20％) 31 cases and group F (mean arterial pressure decreased ＜ 20％) 15 cases,the prognosis among different groups was analyzed.Results The 6 months death / disability rate in group C was higher than that in group A and group B [21.2％ (7/33) vs.1/7,1/6],there was significant difference (P ＜ 0.05).There was no significant difference between group A and group B(P＞ 0.05).Group E patients occurred with hematoma expansion in 1 case,group F occurred with hematoma expansion in 4 cases,and bleeding again in 1 case,incidence of adverse events in group E was lower than that in group F [3.2％ (1/31) vs.5/15],there was significant difference (x2 =5.642,P =0.018).Conclusion Early onset of high blood pressure (＞ 200 mmHg) is the independent risk factor of prognosis,and early actively antihypertensive can effectively reduce the occurrence of hematoma expansion and bleeding again.
