<prompt> Graft Survival in first 48 hours depends onPlasma imbibitionIngrowth of capillaries in donor tissueAmount of Saline in graftConnection between donor and recipient capillaries.  <response>: Ans. is a ie. Plasma imbibition Ref. Sabiston, 18e p2135 17e p2185; Schwartz 9e p165 Skin grafts to survive in the recipient bed, have to become revascularized. This takes place in three distinct phases:Imbibition: refers to absorption of nutrients into the graft, which serves to feed the graft for the first 24 to 48 hrs.Inosculation: is the process whereby donor and recipient capillaries become aligned. During the first two phases, the graft becomes adhered to the recipient bed by fibrous deposition at the interface.Revascularization : is completed by differentiation of the connecting vessels into arterioles and venules.
