    Description / Table of Contents: Abstract Objective: The data of 60 postoperatively sedated and ventilated patients were studied for analysis of oesophageal, bladder, and rectal temperatures. The purpose of the investigation was to clarify whether changes of oesophageal temperature are adequately reflected by bladder and rectal temperatures and whether the rate of rewarming has an influence on the accuracy of the latter two sites. Methods: For temperature recording, a Hi-Lo Temp® esophageal stethoscope (Mallinckrodt Medical), a Foley FC400-18 catheter temperature sensor (Respiratory Support Products, Mallinckrodt Medical), and a rectal temperature probe N401 (YSI) were used. Each probe and matching recording unit was calibrated over a range of 30–40 °C against a reference quartz thermometer (Hewlett packard Model 2801 A) in a thermostated water bath before the investigation. Five measuring points distributed over the whole period of rewarming were evaluated. Patients were assigned to groups with slow and fast rewarming, respectively. Agreement between the methods of measurement was assessed as described by Bland and Altman. Furthermore, differences between the oesophageal and bladder or rectal temperature were checked at each measuring point for statistical significance using the t-test. Results: In regard to oesophageal temperature, the bladder and rectal temperatures had biases of –0.01 °C and –0.03 °C, respectively. Limits of agreement (±2 s) were ±0.68 °C and ±0.82 °C, respectively. The bias of the bladder temperature was independent of the rate of rewarming (Fig. 3). The bias of the rectal temperature, however, differed in regard to the rewarming rate, being +0.06 °C in the group with slow rewarming and –0.13 °C in the group with fast rewarming (Tables 1 and 2, Fig. 1 and 2). These differences were significant for the measuring points 4 and 5 (Fig. 4). Conclusions: Bladder and rectal temperatures can accurately indicate the oesophageal temperature with a very small bias in postoperatively sedated and ventilated patients. Since the rate of rewarming influences the accuracy of rectal temperature readings, monitoring of bladder temperature seems to be more favourable in the postoperative period.
    Notes: Zusammenfassung In einer retrospektiven Untersuchung wurden bei 60 postoperativ nachbeatmeten Patienten während der Phase der Wiedererwärmung die Temperaturen in Ösophagus, Blase und Rektum miteinander verglichen. Ziel der Untersuchung war zu klären, wie gut Blasen- und Rektaltemperatur mit der Ösophagustemperatur übereinstimmten und ob die Wiedererwärmungsgeschwindigkeit einen Einfluß auf die Genauigkeit dieser beiden Meßorte hatte. Material und Methoden: Es wurden fünf Meßpunkte pro Patient berücksichtigt, die zu gleichen Teilen über die Wiedererwärmungsperiode verteilt wurden. Um den Einfluß der Wiedererwärmungsgeschwindigkeit zu erfassen, wurden die Patienten retrospektiv einer Gruppe mit schneller oder langsamer Wiedererwärmung zugeordnet. Ergebnisse: Die Blasentemperatur weist gegenüber der Ösophagustemperatur eine systematische Abweichung von –0,01 °C und eine Meßunsicherheit (±2 s) von ±0,68 °C auf und ist unabhängig von der Wiedererwärmungsgeschwindigkeit. Die Rektaltemperatur zeigt eine systematische Abweichung von –0,03 °C und eine Meßunsicherheit von ±0,82 °C. Die systematische Abweichung der Rektaltemperatur betrug bei langsamer Wiedererwärmung ±0,06 °C, bei schneller Wiedererwärmung hingegen –0,13 °C. Die Unterschiede waren für die Meßpunkte 4 und 5 statistisch signifikant. Schlußfolgerung: Aus diesem Grund scheint die Messung der Blasentemperatur in der postoperativen Phase vorteilhafter zu sein als die Messung der Rektaltemperatur.

    Notes: Abstract The purpose of this study was to estimate the proportion of pregnancies with pregestational diabetes in Germany, to compare the outcome of these pregnancies to pregnancies in nondiabetic mothers and to identify risk factors for poor pregnancy outcomes in mothers with pregestational diabetes. Data of the “Perinatalerhebung Nordrhine” from 1988–1993 were analysed. The Perinatalerhebung is an ongoing quality assurance programme of prenatal and perinatal care in the region of North Rhine (South Western part of North Rhine-Westphalia). During the observation period a proportion of 93%–100% of the annual births in the region (n = ∼100000) were included in the study. Their data had been documented by the obstetricians in a standard multiple choice questionnaire. The outcome parameters perinatal mortality, macrosomia, prematurity, and malformations were analysed in relation to several defined explanatory variables. There were 2,402 births in mothers with pregestational diabetes (0.4% of all births). The proportions of poor pregnancy outcomes in women with pregestational diabetes were 2.8% for perinatal mortality, 27.6% for macrosomia, 21.1% for prematurity and 2.1% for malformations . The respective relative risks compared to the non diabetic mothers were 4.3 (95% CI 3.4–5.5) for perinatal mortality, 3.1 (95% CI 2.9–3.3) for macrosomia, 2.7 (95% CI 2.5–2.9) for prematurity and 1.7 (95% CI 1.3–2.3) for malformations . The main risk factor for perinatal mortality in children of diabetic mothers after adjustment for maternal smoking, ethnicity, parents' professional achievement, type of obstetric hospital, and maternal age was substandard use of prenatal care. Conclusions The prevalence of births from mothers with pregestational diabetes and their pregnancy outcomes were similar to those in other Western countries. The standard for non-diabetic mothers has not been reached yet. Further improvements may be achieved if all diabetic women are convinced to use the standard prenatal care facilities throughout pregnancy.
