Abstract:
Objective Gastrointestinal rehydration is a simple and effective method in treatment of burn shock during war-time, fire disaster and other harsh conditions , and practice has proved the exact curative effect of HCO 3 salt sugar liquid .This article was to investigate the effect of pyruvate-enriched oral rehydration solution ( Pyr-ORS ) on intestinal mucosal blood flow ( IMBF ) , activity of Na +-K+-ATPase and intestinal absorption rate during en-teral resuscitation of a 35% TBSA third-degree scald in rats . Methods 90 male rats were randomly divided into 5 groups: scald without fluid resuscitation ( S group ); sham scald resuscitated with HCO3 salt sugar liquid ( SS HCO3 group ); sham scald resuscitated with Pyr-ORS ( SS Pyr-ORS group ); scald resuscitated with HCO 3 salt sugar liquid (S HCO3 group); scald resuscitated with Pyr-ORS (S Pyr-ORS group) (n=18).Each group was divided into 2 subgroups of 1.5 and 4.5 h after scald injury.Intestinal absorption rate of water and Na +, IMBF and activity of Na +-K+-ATPase were detected on each group . Results Compared with shame scald groups , the intestinal absorption rates of water and Na +decreased ob-viously in scald groups with fluid resuscitation (P<0.05);at 1 h after scald injury, the intestinal absorption rates of water and Na +in S Pyr-ORS groups were both higher than those in S HCO 3 groups(P<0.05).Compared with shame scald groups , IMBF and activity of Na+-K+-ATPase at 1.5 and 4.5 h after scald injury decreased obviously in scald groups with fluid resuscitation (P<0.05); at 1.5 and 4.5 h after scald injury, IMBF in S Pyr-ORS groups (95.250 ±5.096/112.765 ±7.215) were greater than those in S HCO3 group (80.764 ±7.852/94.671 ±8.469), which was of statistical significance (P<0.05). Conclusion Pyr-ORS is a simple and effec-tive method in treatment of burn shock during wartime , fire disaster and other harsh conditions .
