[Comparison between hypo- and hyperglucidic diets on protein sparing in major visceral surgery (author's transl)].

The authors compare the protein sparing effect of two diets, exclusively intravenous, including the same protein intake, but a different caloric intake, 21 calories/gm nitrogen for diet "A" (20 cases); 138 calories/gm nitrogen for diet "B" (20 cases). This has been observed during the six post-operative days of major visceral surgery: oesophagectomy, total gastrectomy, colic or rectocolic exeresis, sequestrectomy for acute pancreatitis, lots having been drawn for the diets. Daily nitrogen balances have been made and plasmatic and urinary levels of amino-acids have been measured before surgery and on the third and fifth post-operative days.

[False diagnosis of post-operative massive pulmonary embolism. Nine observations (author's transl)].

After having studied nine observations about patients referred to them for embolectomy under CEC on suspicion of massive pulmonary embolism, the authors describe five differential diagnosis and how they can be reached. A low central venous pressure, an hypoxaemia sensitive to oxygenotherapy, a high pulmonary wedge pressure or the lack of diastolocapillary gradient, and, last of all, a real hypocoagulability attained by the use of low and daily doses of heparin must make one cautious. Yet, if a doubt should persist, an angiography and/or a scintigraphy will be asked for.
