[Continuous glucose monitoring using the glucose sensor CGMS in metabolically normal pregnant women during betamethasone therapy for fetal respiratory distress syndrome].

PURPOSE: The object of this study was to evaluate the effect of betamethasone therapy on maternal glucose levels, to observe the incidence of ketoacidosis and gestational diabetes as well as to judge fetal outcome. METHODS: 26 patients underwent measurement with the CGMS for at least 72-hour. Morning urine was examined for ketones and glucose, venous blood was drawn from a hand vein for blood gas measurements. At a minimum of seven days after the last betamethasone treatment, an oral glucose tolerance test was performed to exclude gestational diabetes. For fetal outcome weight, body length, head circumference, APGAR and pH of umbilical cord blood were determined. RESULTS: All patients showed transient hyperglycaemia from day 1 to day 2 with normoglycaemia on day 3 (mean +/- SD: 129.6 +/- 20 mg/dL on day 1, 127.1 +/- 17.7 mg/dL on day 2, 96.7 +/- 12.9 mg/dL on day 3, and 91.3 +/- 17.8 mg/dL on day 4). There was a significant fall (p < 0.01) of the mean glucose levels between day 1/3, day 1/4, day 2/3, day 2/4. Neither acidosis (pH < 7.35) nor clinically relevant BE/lactate shifts were seen. Ketonuria was detected in 30 % of the patients before betamethasone, rose to 50 % (on day 1), fell to 24 % (on day 2), and 6 % (on day 3). One week later one patient (4 %) was diagnosed as having gestational diabetes, while four (17 %) showed impaired glucose tolerance. Fetal outcome showed no significant difference compared to the average of the Virchow Klinikum. CONCLUSION AND DISCUSSION: Pregnant patients have high glucose measurements for two days during betamethasone therapy. No maternal acidosis and no diabetic delayed metabolic effects were seen, and fetal outcome showed good results. A prophylactic use of insulin is not generally needed in healthy women.

Optimal timing for postprandial glucose measurement in pregnant women with diabetes and a non-diabetic pregnant population evaluated by the Continuous Glucose Monitoring System (CGMS).

OBJECTIVE: Using the Continuous Glucose Monitoring System (CGMS; Medtronic Minimed) for a group of pregnant women with and without glucose intolerance, we attempted to answer the following questions: (1) when does the physiological peak of postprandial glucose occur?; (2) do non-diabetic pregnant women and pregnant women with diabetes have different postprandial glucose profiles?; and (3) what is the optimal time for postprandial glucose measurement rated according to clinical outcome? METHODS: We included 53 pregnant women in our study. Based on the criteria of the German Diabetes Association (fasting, 5.0 mmol/L; 1-h, 10.0 mmol/L; 2-h, 8.6 mmol/L) we included 13 women with gestational diabetes, four with type 1 diabetes and 36 non-diabetic pregnant (NDP) women. Gestational and type 1 diabetics were classed as one group: pregnancy complicated by diabetes (PCD). Patients with carbohydrate intolerance underwent dietary counseling in accordance with the recommendations of the American Diabetes Association. Patients received a CGMS for use over 72 h. This was calibrated seven times a day with an Accu-Check. The pre- and postprandial glucose levels were documented at 15-min intervals for 3 h from the beginning of each meal. The postprandial data from the three meals were added. The group was divided according to three clinical outcome parameters: mode of delivery, birth weight percentile, and diabetes-associated complications. RESULTS: Statistically significant differences between groups were found for body mass index, fetal birth weight and oral glucose tolerance test. No significant differences were found for age, parity and gestational age, mode of delivery, and diabetes-associated complications. The sensor provided similar numbers of measurements in both groups (278+/-43 vs. 298+/-73, P = 0.507). The postprandial glucose peak was reached after 82+/-18 min in the non-diabetics vs. 74+/-23 min in the PCD group (not significant). Postprandial glucose values were normally slightly higher in PCD (not significant). We added the postprandial glucose values at each time interval for the three meals for each day. For the sum, there was a significant difference between the measurements at 120 min and at 135 min postprandial (P < 0.05). Dividing the group by clinical outcome showed a significant difference between the postprandial time intervals of 75 min and 105 min (P < 0.05). In addition, the time interval was different from 60 min to 135 min for the mode of delivery and birth weight percentile (P < 0.05). CONCLUSION: The 120-min interval is too long and has a lower correlation to clinical outcome parameters than earlier measurements. Our findings show that the optimal time for testing is between 45 and 120 min postprandial. Based on our practical experience and dietary recommendations, we would prefer a 60-min interval, because patients can calculate this more easily and can have more freedom to eat the recommended number of snacks.

A randomized trial evaluating a predominantly fetal growth-based strategy to guide management of gestational diabetes in Caucasian women.

OBJECTIVE: To compare the management of Caucasian women with gestational diabetes (GDM) based predominantly on monthly fetal growth ultrasound examinations with an approach based solely on maternal glycemia. RESEARCH DESIGN AND METHODS: Women with GDM who attained fasting capillary glucose (FCG) <120 mg/dl and 2-h postprandial capillary glucose (2h-CG) <200 mg/dl after 1 week of diet were randomized to management based on maternal glycemia alone (standard) or glycemia plus ultrasound. In the standard group, insulin was initiated if FCG was repeatedly >90 mg/dl or 2h-CG was >120 mg/dl. In the ultrasound group, thresholds were 120 and 200 mg/dl, respectively, or a fetal abdominal circumference >75th percentile (AC>p75). Outcome criteria were rates of C-section, small-for-gestational-age (SGA) or large-for-gestational-age (LGA) infants, neonatal hypoglycemia (<40 mg/dl), and neonatal care admission. RESULTS: Maternal characteristics and fetal AC>p75 (36.0 vs. 38.4%) at entry did not differ between the standard (n = 100) and ultrasound groups (n = 99). Assignment to (30.0 vs. 40.4%) and mean duration of insulin treatment (8.3 vs. 8.1 weeks) did not differ between groups. In the ultrasound group, AC>p75 was the sole indication for insulin. The ultrasound-based strategy, as compared with the maternal glycemia-only strategy, resulted in a different treatment assignment in 34% of women. Rates of C-section (19.0 vs. 18.2%), LGA (10.0 vs. 12.1%), SGA (13.0 vs. 12.1%), hypoglycemia (16.0 vs. 17.0%), and admission (15.0 vs. 14.1%) did not differ significantly. CONCLUSIONS: GDM management based on fetal growth combined with high glycemic criteria provides outcomes equivalent to management based on strict glycemic criteria alone. Inclusion of fetal growth might provide the opportunity to reduce glucose testing in low-risk pregnancies.

Transvaginal and transabdominal extended field-of-view (EFOV) and power doppler EFOV sonography in gynecology: advantages and applications.

OBJECTIVE: To evaluate the possible advantages, applications, and usefulness of real-time transabdominal and transvaginal extended field-of-view sonography combined with power Doppler sonography in gynecology. METHODS: A series of 63 gynecologic patients, referred for preoperative sonographic examination and for whom the examiner thought that extended field-of-view sonography might be helpful in imaging pathologic findings, were selected. Patients were examined with conventional vaginal and abdominal B-mode sonography, extended field-of-view sonography, and power Doppler extended field-of-view sonography. A sonographic system with 3.5- to 7-MHz transducers was used to study and document pathologic findings. RESULTS: Extended field-of-view sonography provided a superior overview of pathologic findings and topography by creating a single image showing the relationship to reference structures. The combination of power Doppler extended field-of-view sonography provided additional information on the perfusion pattern in huge masses. In comparison with conventional sonographic images, the extended field-of-view sonographic images were easier to interpret by the referring or nonexamining physician. A list of proposed gynecologic applications for the use of extended field-of-view sonography was compiled. CONCLUSIONS: The extended field-of-view and power Doppler extended field-of-view sonographic technique provides documentation of surroundings, topographic orientation, and perfusion patterns in large pelvic masses and findings that exceed the limitations of the conventional sonographic sector. The clinical applications and advantages of extended field-of-view and power Doppler extended field-of-view imaging in gynecologic sonography are illustrated.
