A comparison of Ringer's lactate and acetate solutions and resuscitative effects on splanchnic dysoxia in patients with extensive burns

Abstract We compared the effects of Ringer's lactate(RL) and acetate (RA) solutions on parameters of splanchnicdysoxia such as PgCO 2 (PCO 2 of gastric mucosa) and pH i (pH of gastric mucosa) using a gastric tonometer, in addition to blood markers such as the serum arterial level of lactate, base excess, ketone bodyratio, and antithrombinduring the first 72h of the resuscitationperiod in patients with burns covering 30% or more of their body surface. A prospective study was conducted in the university tertiary referral centers. There were no significant differences in the average age, TBSA (total burn surface area), and resuscitativefluid volume during the first and second 24h between the two groups. In the RA group, PCO 2 gap values calculated employing the formula: PgCO 2 −PaCO 2 (arterial PCO 2 ), and pH gap calculated by: pH a (arterial pH)−pH i , improved to the normal ranges at 24h postburn, which was significantly faster than in the RL group. On the other hand, there were no significant differences in blood parameters between the two groups over the course. These results suggest that fluid resuscitationwith RA may more rapidly ameliorate splanchnicdysoxia, as evidenced by gastric tonometry, compared to that with RL.
