Abstract: Objective　To investigate the acute pain symptoms in patients with acute pancreatitis and to analyze its influence on hospitalization time.Methods　Patients with acute pancreatitis who were admitted to the First Affiliated Hospital of Soochow University and the Second Affiliated Hospital of Soochow University between November 2015 and June 2016 were selected through a convenient sampling method.The patients' demographic data，clinical materials were collected.The cumulative time of pain was recorded. The degree of pain was assessed using an internationally adapted numerical rating scale （NRS）.Results　A total of 178 questionnaires were distributed，and 160 were returned，of which 150 were valid；the effective recovery rate was 84.3%.The cumulative pain time for the 150 patients was 48（30，60）h，the incidence of moderate-to-severe pain 0 to <2 h after admission was 98.7% （148/150），and the cumulative time of moderate-to-severe pain was 2 （2，2） h.The incidence of moderate-to-severe pain 2 to <12 h after admission was 94.7% （142/150），and the cumulative time of moderate-to-severe pain was 5 （3，8） h.The incidence of moderate-to-severe pain 12 to <24 h after admission was 47.3% （71/150），and the cumulative time of moderate-to-severe pain was 0 （0，4） h.The incidence of moderate-to-severe pain 24 to <48 h after admission was 7.3% （11/150），and the cumulative time of moderate-to-severe pain was 0 （0，0） h.There were significant differences in the incidence of moderate-to-severe pain and severity of pain （NRS scores） in different time periods （0 to<2 h，2 to <12 h，12 to <24 h，and 24 to <48 h） （P<0.05）.The hospitalization time was （11.4±5.5） d.Correlation analysis showed that pleural effusion，ascites fluid，Ranson score，complications，cumulative total pain time，cumulative time of moderate-to-severe pain at 2 to <12 h，incidence of moderate-to-severe pain at 12 to <24 h，incidence of moderate-to-severe pain at 24 to <48 h，and NRS scores at 24 to <48 h were correlated with hospitalization time （P<0.05）.Multivariate linear regression analysis showed that ascites fluid （B=2.524），Ranson score （B=3.905），cumulative total pain time （B=0.063），and cumulative time of moderate-to-severe pain at 0 to <2 h （B=-3.583） were factors influencing patient hospitalization time （P<0.05）.Conclusion　Patients with acute pancreatitis have a long duration of pain in the acute phase，and the pain is relatively severe.Clinicians should pay attention to the collection of mild pain data and take active and effective measures to intervene to shorten hospitalization time.
