CRYSTALLOID AND COLLOID FLUID THERAPY FOR MAINTAINING THE PLASMA AND BLOOD VOLUME IN BUFFALO SUBJECTED TO OBSTETRICAL MANEUVERING

Abstract

The impact of crystalloid (Normal or Hypertonic saline) and colloid (Dextran-40 or Polygeline) fluid therapies on dehydration status of twenty-four dystocia affected buffalo subjected to obstetrical maneuvering was monitored through plasma and blood volume evaluation. Depending upon the fluid therapy administered, the buffalo were divided (n=6 each) into groups namely, NSS (Normal saline solution 5-10 L, i.v.), group H+O (7.2% Hypertonic saline solution, HSS @ 4 ml/kg b wt, i.v. + Oral fluid/freshwater @ 40 ml/kg b wt), group D+H+O (Dextran-40 @ 20 ml/kg b wt, i.v. + HSS + Oral fluid) and group P+H+O (Polygeline @ 20 ml/kg b wt, i.v. + HSS + Oral fluid). Blood samples were collected following the delivery of fetus, before the start of fluid therapy (0 h) and at 6, 12 and 24 h after the start of fluid therapy. The buffalo receiving intravenous NSS or HSS+Oral fluid exhibited a less persistent increase (p<0.05) in plasma and blood volume after the start of fluid therapy (till 6 and 12 h, respectively). However, the increase (p<0.05) in plasma and blood volume persisted till 24 h following the addition of colloids in the crystalloid fluid therapy (HSS+Oral fluid). In brief, colloids can be used to maintain the plasma and blood volume over a longer period of time in buffalo subjected to obstetrical maneuvering.
