Background/objectives: Aggressive fluid resuscitation is recommended for initial management of acute pancreatitis. However, there are few studies which focus on types of fluid therapy.
Methods: We performed a randomized controlled trial in patients with acute pancreatitis. The patients were randomized into two groups. Each group received Normal Saline solution (NSS) or Lactated Ringer's solution (LRS) through a goal-directed fluid resuscitation protocol. Systemic inflammatory response syndrome (SIRS) at 24 and 48 h, mortality, presence of local complications and inflammatory markers were measured.
Results: Forty-seven patients were included. Twenty-four patients (51%) received NSS and 23 patients received LRS. There was significant reduction in SIRS after 24 h among subjects who resuscitated with LRS compared with NSS (4.2% in NSS, 26.1% in LRS, P = 0.02). However, SIRS reduction at 48 h was not different between groups (33.4% in NSS, 26.1% in LRS, P = 0.88). Mortality was not different between NSS and LRS (4.2% in NSS, 0% in LRS, P = 1.00). CRP, ESR and procalcitonin increased at 24 h and 48 h after admission with no difference between the two groups. Local complications were 29.2% in NSS and 21.7% in LRS (P = 0.74). The median length of hospital stay was not significantly different in the two groups (5.5 days in NSS, 6 days in LRS, P = 0.915).
Conclusions: Lactated Ringer's solution was superior to NSS in SIRS reduction in acute pancreatitis only in the first 24 h. But SIRS at 48 h and mortality were not different between LRS and NSS.
