High CVP in anticipation of heavy blood loss
Decreased MAP to reduce arterial bleeding
Decreased CVP to reduce venous bleeding
Normal MAP in anticipation of heavy blood loss
Normal CVP to ensure adequate filling of the heart

You are anaesthetising a 25 year male for an open appendicectomy. He has a Fontans circulation on a background of tricuspid atresia. The best strategy to manage his ventilation intraoperatively would be:
Ensure adequate PEEP
Decrease inspiratory time
Alter the I:E Ratio from 1:3 to 1:1.2
Increase Inspiratory time but with reduced inspiratory pressures

Consider the following arterial blood gases. (Ref ranges in brackets)
-Bicarbonate 18 mmol.l-1 (18-25)
-Base excess -7 mmol.l-1 (-4- +3)

A 70 year old is is intubated and ventilated post-laparotomy. He has CSL running @60ml/hr, with an NGT on suction with continuing high output. His ABG shows an appropriate pO2, pCO2 32, pH 7.66, Na 144, K 3.5, Cl 76. He has a normal creatinine and raised urea. How should you improve his acid base status? (Had a very very very long stem, with very long answers, but this was the gist, and I'm pretty confident with the answers except the first 2 fluid options).
