How things can change, so quickly!

I popped in at lunchtime to see Sarah, who had recieved her blood and platelet transfusions over the past 18 hours and she was sat up in bed feeling quite well.On my return to the ward after work tonight I found Sarah huddled up in bed with the shivers and a temperature of 38.5c. Apparently, an hour after I had left her at lunchtime Sarah came over with the shivers and was going from hot to cold to hot.Sarah's shivers become predominantly worse and I have never seen her look or react so ill - the doctors were paged and a shot of pethidine. This would help stop the shivers, but ultimately less than a minute after it was given Sarah was uncontrollably sick but thankfully the shivering had ceased and now Sarah was burning up.Sarah has an infection, we are waiting for the blood cultures to grow some bacteria for analysis and is still running a high temperature. So yet again upon her return to Barts within a few days she is sick again - and I thought that hospitals were supposed to make you feel better.......
