Why was TPN discontinued and D10W hung in its place during surgery?

Question 2

CJ's weight is now down to 168 . Calculate his total caloric needs by calculating his BEE and an appropriate energy expenditure factor. Use the Harris-Benedict equation and appropriate factor found in Appendix A or use a formula of your own choosing.

Answer to Question 1

The stress of surgery will cause a change in BEE, insulin utilization, lipid utilization, and possible fluid shifts. This would make it impractical, if not impossible, to monitor and control TPN during surgery. However, if TPN were stopped completely without providing a source of glucose, the blood glucose level could drop very low; therefore, D10W was hung.

Answer to Question 2

BEE = 66 + 13.7 wt + 5 ht - 6.8 age
= 66 + 13.7 76.4 + 5 177.8 6.8 58
= 66 + 1047 + 889 394
= 2029 394
= 1635

Using a stress factor of 1.4: 1635 1.4 = 2289
