nbme - miss_ismail_79 - ArchivalUser - 08-02-2006 27 yr old woman--b/l femoral shft #--20 mins after blood transfusion of 1 unit packed red blood cells--she develops flank pain--haematuria---101.F--- most likely cause abo incompatability contamination of transfused blood fat embolism synndrome reaaction to leukocye antigens in thansfused blood retroperitoneal bleed 0 - ArchivalUser - 08-02-2006 reaaction to leukocye antigens in thansfused blood ????????????????? 0 - ArchivalUser - 08-02-2006 reteroperitoneal bleed 0 - ArchivalUser - 08-02-2006 it is classical abo incompatibility leading to hemolysis pt has hematuria and flank pain plus temp . only contamination of blood would give rise to temp only retroperitoneal bleed. why and would not give rise to hematuria and flank pain both sides reaction to leucocyte antigen would be allergic type and would not start around in 20 min unless she has been exposed to same donor before. fat embolism does not present this early and would present with respy distress 3 - ArchivalUser - 08-02-2006 i think i go with ajeet , he gave us the explanation yesterday which i think is coorrect. u have hematuria meaning rbcs in urine not hemoglobinuris brought about by lysis as in the other choices 0 - ArchivalUser - 08-02-2006 how do u explain hematuria in the urine and why after 20 min of the bt and why temp. temp should rise only if clot forms and we do refer any red color urine as hematuria. then investigate that it has rbc or not. so why does ajeet says its retroperitoneal bleed what is the explanation. i go with transfusion reaction because it is classically . saw few pt with those symptoms 0 - ArchivalUser - 08-04-2006 My answer is retroperitoneal bleed, but I am not sure. Retroperitoneal bleed because of injury to renal tracts. And I think you can get a temperature with even uneventful blood transfusion. 0 - ArchivalUser - 08-04-2006 why not lecocyte....or ab incompatibility? 0 - ArchivalUser - 08-04-2006 i go with abo incompatibility. massive haemoglobinuria can lead to pigment induced tubular necrosis that will lead to haematuria. hla reaction should take longer than 20 mins. retoperitoneal bleed can only cause haematuria if there is an associated renal or urinary tract injury. nothing in the stem is suggestive of this and rather the symptoms are tied in time to bld transfussion. 0 - ArchivalUser - 08-04-2006 this Q has been rehashed....and each of those times the Q stem keeps getting shorter and shorter, and the info in it lesser! |
