The insufficiency was caused by ligation of the pedicle vessels (epigastric superior artery and vein) on the 3rd, 4th, 5th and 7th d after flap replantation, and by occlusion of these vessels with microclips for 2 h. Only the temperature differences between the intact and the operated skin surface were used to estimate blood flow efficiency not, the absolute values. These differences were statistically insignificant between the intact right and left abdominal skin areas and between the intact skin and the vital flap surfaces. In these cases the maximal temperature differences were 0.52 degree C. Only during the early postoperative period (3-days ligation group) a correlation between blood flow insufficiency and flap viability is expressed by temperature differences (2.14 degrees C). Later on (7-days ligation group) a temperature difference of 1.87 degrees C was no evidence of disturbed wound healing. Thus in advanced stages in myocutaneous flaps differences of blood flow and neovascularization respectively cannot be estimated reliably by measurements of skin surface temperature. However, temperature differences greater than 2 degrees C signal impaired flap viability.","PeriodicalId":76864,"journal":{"name":"Zeitschrift fur Versuchstierkunde","volume":"32 1","pages":"33-9"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13853111","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}

All animals were maintained at constant body temperature of 38 degrees C and artificially respirated via a tracheal cannula monitoring the end expiratory CO2 concentration. Mean arterial blood pressure (carotid artery) and heart rate were continuously recorded. Arterial acid-base status and pO2 were tested. Mean arterial blood pressure and heart rate were found to be somewhat higher in the neuroleptanesthetized animals. Under chloralose-urethane anesthesia and neuroleptanesthesia the mean arterial blood pressure amounted to 56 and 62 mm Hg, respectively. These findings correspond to data given in the literature concerning the mean pressure in unanesthetized guinea pigs. The mean heart rates of 295 and 316 min-1, respectively are somewhat higher compared to the normal range. Under both anesthesias, the arterial acid-base status was within the normal limits of unanesthetized animals. The mean arterial pO2 of 80.9 and 76.5 mm Hg was relatively low. The present studies have shown that chloralose-urethane as well as droperidol-fentanyl with pentobarbital are useful, under controlled artificial respiration, to achieve long-term anesthesia maintaining nearly normal systemic circulatory and respiratory conditions.","PeriodicalId":76864,"journal":{"name":"Zeitschrift fur Versuchstierkunde","volume":"32 1","pages":"25-31"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13708901","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}
