Although we make every effort to avoid errors in the Storm Anesthesia Manual, the task is enormous and never ending. We always appreciate our readers great feedback on any errors that may have entered our book without our knowledge!
The following is the errata list for the current edition of SAM:
In the section “Water balance” we have made a few corrections and clarifications. The full section should read as follows:
The renal blood flow is 1,800 liter/day (20-25% of cardiac output) and the kidneys will filter approximately 10% of this for an ultrafiltrate production of 180 liter/day. The kidneys will reabsorb over 99%, so only 1-2 liters will be excreted as urine.
The majority of water is reabsorbed by passively following Na+, which happens in the proximal tubule, where 65% is reabsorbed by isosmotic reabsorption. The remaining water will be reabsorbed in the thin descending tubule (20%) and the late distal tubule and collecting duct. Absorption in the late distal tubule and collecting duct is controlled by ADH and rely on principal cells and their aquaporin 2 channels, which are inserted when ADH is increased.
