Hematocrit decrease was seen after both drugs, lasting longer when they were combined. We conclude that DDAVP and dextran may be used concomitantly, each with maintained beneficial properties. DDAVP will still act hemostatically by increasing platelet adhesiveness, factor VIII and von Willebrand factor and by shortening the dextran-induced prolongation of bleeding time.

By means of intraluminally placed balloon catheters (Tonomitior) permeable to CO2, intramucosal pH (pHi) was calculated using the Henderson-Hasselbalch equation. Cardiopulmonary hemodynamics and portal blood flow were measured using Swan-Ganz catheters. Samples were taken from the gastrointestinal tract for histological examination. Nine pigs were given i.v. E. coli infusion while six pigs served as sham controls and were given an equivalent amount of Ringer's solution only. All septic animals developed hemodynamic signs of septic shock. Gastric, small intestinal and sigmoid colonic pHi decreased gradually during the four hour observation period. In the small intestine and the sigmoid colon the decrease was significant already after one hour (p less than 0.01 and p less than 0.02, respectively). Microscopic examination of tissue specimens obtained 4 hours following induction of sepsis revealed normal or close to normal findings in all the sham and in more than half of the septic animals. These findings indicate that abnormally low gastrointestinal intramucosal pH may be found early in septicemia, preceding microscopically detectable damage by several hours. It is concluded that the tonometer technique does provide early detection of gastrointestinal ischemia in septic shock.</p>","PeriodicalId":7005,"journal":{"name":"Acta chirurgica Scandinavica","volume":"156 9","pages":"613-20"},"PeriodicalIF":0.0,"publicationDate":"1990-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13417576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of these, 68% initially consulted a general or private practitioner, whereas only 21% directly consulted surgical departments. The interval from the initial consultation to operation, analysed multivariately, was correlated to the number of referral-steps (13 vs. 75 days), the category of physician initially consulted (15 vs. 33 days), and the outcome of a combined positive or negative mammography + aspiration cytology (13 vs. 58 days).

At the end of the second postoperative night an oxygen stimulation test (10 l/min by face mask) was carried out in eight of the 10. Median SpO2 was 91% (range 82-95) on the second, and 91% (86-95) on the third, postoperative nights, respectively. Six patients had intermittent episodes of desaturation to less than 80%, each of less than one minute's duration. PtcO2, but not PscO2, followed the episodic variations in SpO2. PscO2 was 58 mmHg (46-69) on the second postoperative night and 61 mmHg (48-71) on the third postoperative night. PscO2 correlated with SpO2 in all but one patient who had lower PscO2 than expected from the measured SpO2 and estimated PaO2. Oxygen treatment increased individual PscO2 by 14 mmHg (9-49), PtcO2 by 38 mmHg (10-104), and SpO2 to 99% (95-100), but stable PscO2 was not achieved within the 20 minute period of treatment.
