Objective To discuss curative effect of early fluid resuscitation new strategies on older severe acute pancreatitis. Methods 75 cases of elderly SAP patients were selected as research object and were divided into group treatment (n=37 ) and group control (n = 38).Group control was used conventional treatment method，and group treatment was used early fluid resuscitation treatment method.The indicators of two groups were observed ,compared and analysis. Results Before treatment, the Ranson score, APACHE II score, CTSI score of two groups were compared with and the difference had`t statistical significance ( P>0.05).But after treatment,the Ranson score, APACHE II score, CTSI score of group treatment respectively was (3.3± 1.1) points, (9.5 ±2.8) points, (4.4 ±1.3) points，and were all significantly lower than group control (3.9±1.3) points, (10.8 ±2.5) points, (5.2 ±1.9) points (all P <0.05). complication Incidence rate of group control and group treatment was respectively 55.3% and 32.4%，the difference was statistically significant ( P<0.05). Hospitalization time of group control was (27.5 ±4)days,and was significantly faster than group treatment whose hospitalization time was (22.3 ±3.2) days ( P<0.01). Hospitalization costs of group control and group treatment was respectively (43562.3± 185.7) yuan and (44109.7 ±134.5) yuan，the difference was not statistically significant ( P>0.05).Conclusion early fluid resuscitation therapy can effectively improve and stabilize the microcirculation of older SAP patients, and decrease the complications incidence rate.
