Objective. To increase the effciency of spinal anesthesia (SA) in operative delivery of pregnant women with type 1 diabetes mellitus (DM).Materials and methods. A dynamic assessment of the clinical effciency of spinal anesthesia in cesarean sections was performed in 123 pregnant women with DM. The level of the sensor and motor block was determined depending on the dose of a 0.5% hyperbaric solution of bupivacaine calculated according to the original method.Results. The SA method in cesarean sections in pregnant women with diabetes mellitus has been proposed taking into account the dosage of a hyperbaric solution of bupivacaine depending on the patient`s height and gestational age. The application of this method provided the development of the necessary degree of the sensory and motor block by the eight minute and created the requisite conditions for a cesarean section.Conclusion. The proposed method of the calculation of the hyperbaric solution dosage for subarachnoid anesthesia taking into account the patients` height and gestational age makes it possible to ensure the necessary degree of the sensor block at the level of 4-5 thoracic segments and suffcient relaxation in the surgical area during a cesarean section.

The prevalence of obese parturients is increasing worldwide. This review describes safe analgesic techniques for labor and anesthetic management during cesarean sections in obese parturients. The epidural analgesic technique is the best way to provide good pain relief during the labor phase and can be easily converted to a surgical anesthetic condition. However, the insertion of the epidural catheter in obese parturients is technically more difficult compared to that in non-obese parturients. The distance from the skin to the epidural space increases in proportion to the body mass index (BMI): 4.4 cm in mothers of normal weight and 7.5 cm in mothers with BMI 50 and above. Neuraxial blocks are the ideal anesthetic methods and gold standard techniques for cesarean section in pregnant women with obesity. Single-shot spinal anesthesia is the most common type of anesthesia used for cesarean sections. The advantage of single-shot spinal anesthesia is a dense-sufficient block of rapid onset. A combined spinal-epidural (CSE) anesthetic technique is also recommended as an attractive alternative method. In obese parturients, the operation time can be longer than expected, and therefore, the CSE technique provides the advantage of rapid onset and intense block for prolonged operation with postoperative pain control. The risk of postoperative complications is very high in obese parturients. Therefore, detailed communication of the parturient's medical condition and the details of surgery and anesthesia between the anesthesiologist and obstetrician is important prior to cesarean section in obese pregnant women.

Background: Spinal anesthesia is the method of choice for the cesarean section. Hypotension is a common complication of this method. Objectives: This study aimed to compare the effect of spinal anesthesia in the sitting and lateral positions on the onset time of sensory block and hemodynamic condition in cesarean sections. Methods: In this clinical trial, 106 elective cesarean section candidates under spinal anesthesia were selected and randomly divided into two groups: spinal anesthesia in the sitting position (group S) and the lateral position (group L). The onset time of the sensory block, quality of sensory and motor block, hemodynamic condition, frequency of hypotension, nausea, and vomiting, and the doses of ephedrine and atropine were compared between both groups. Data were analyzed with SPSS version 16 software at a 95% confidence level. Results: There was no statistically significant difference between the two groups in terms of age. The frequency of hypotension in L and S groups was 24.5% and 57.7%, respectively (P = 0.001), in minute 6 after spinal anesthesia and 5.7% and 36.5%, respectively (P < 0.001), in minute 8 after spinal anesthesia. The mean time to reach the sensory level of T6 was 1.30 ± 0.43 min versus 4.54 ± 2.12 min (P < 0.001), motor block score in minute 5 was 2.98 ± 0.14 versus 2.82 (P = 0.044), and ephedrine dose was 11.5 mg and 16.92 mg in the L and S groups, respectively (P = 0.010). The maximum sensory-motor block and satisfaction of women with spinal anesthesia were significantly higher in the lateral position than in the sitting position (P < 0.05). Conclusions: Cesarean sections under spinal anesthesia in the lateral position than in the sitting position lead to a more rapid sensory and motor block, reduced ephedrine consumption, and enhanced satisfaction of women.

Objective: The aim of this study is to evaluate the obstetric and neonatal outcomes of pregnant women delivering large for gestational age (LGA) infants. Material and Methods: A total of 399 pregnant women giving birth to LGA infants in the Gynecology and Obstetrics Department of Dicle University Medical Faculty Hospital between January 2014 and December 2018 were included in this retrospective study. Demographic features, pregnancy and infant data, delivery type (vaginal delivery/cesarean delivery), and patients’ indications for cesarean section were assessed. Results: The mean age of the patients was 32.34±6.63, their gravida was 5.16±2.65 and parity was 3.55±2.36. The mean gestational week was 37.12±2.840 weeks and the mean birth weight was 3922.46±643.546 g. Of all patients, diabetes was detected in 28.5%, polyhydramnios in 11.3%, placental invasion anomaly in 4%, and preeclampsia in 9%. While 83.7% (334) of the patients underwent cesarean section, the remaining 16.3% (65) underwent normal delivery. 3.25% (13) of the patients developed complications during delivery. The rate of fetal anomaly was 11.7% (47) in existing pregnancies while the rate of fetal death was 5.01% (20). Conclusion: A cesarean delivery was performed in the majority of pregnant women with a suspected LGA infant. This group of patients exhibited a very high rate of gestational diabetes mellitus and diabetes mellitus. Existing pregnancies constitute a specifical pregnancy population that should be taken into consideration regarding probable complications and problems with the infant.

Abstract Background Due to metabolic changes in the second trimester and the increasing number of pregnant women with obesity and advanced maternal age, the incidence of gestational diabetes mellitus (GDM) remains high. This study aimed to evaluate the effects of GDM on fetal cardiac morphology and function, and to determine whether these changes increase with increasing estimated fetal weight (EFW). Methods Fifty-eight women with GDM (GDM group) and 58 women with a healthy pregnancy (control group) were included in this prospective observational cohort study. Each group included subgroups of 31 pregnant women with a gestational age between 24+0 weeks and 27+6 weeks as well as 27 pregnant women with a gestational age between 28+0 weeks and 40+0 weeks. For all fetuses, a cine of 2–3 s in the four-chamber view was obtained, and online speckle-tracking analysis was performed using the GE Automatic Fetal Heart Assessment Tool (fetal HQ; General Electric Healthcare Ultrasound, Zipf, Austria) to measure the global sphericity index (GSI), global longitudinal strain (GLS), fractional area change (FAC), 24-segment sphericity index (SI), and 24-segment end-diastolic diameter of the left ventricle (LV) and right ventricle (RV). Data were analyzed using the independent t-test and Wilcoxon rank-sum test, as applicable. Results The GDM group (mean HbA1c value was 5.3 ± 0.57 mmol/L) showed a lower GSI value than the control group (1.21 vs. 1.27, P = 0.000), which indicated a rounder shape of the heart. In addition, fetuses in the GDM group demonstrated significant impairment in cardiac function compared to those in the control group (LV-GLS: -18.26% vs. -22.70%, RV-GLS: -18.52% vs. -22.74%, LV-FAC: 35.30% vs. 42.36%, RV-FAC: 30.89% vs. 36.80%; P = 0.000 for all). Subgroup analyses according to gestational age (24+0–27+6 weeks and 28+0–40+0 weeks) showed that the statistical differences were retained between the GDM and control groups in each subgroup. Conclusions Fetuses of women with GDM present with signs of biventricular systolic dysfunction according to deformation analysis using fetal HQ. Additionally, the heart had a rounder shape in the GDM group than in the control group. This study showed that fetal HQ can be used to assess fetal cardiac morphology and function easily and quickly, and the effects of GDM on fetal cardiac morphology and function appeared from the second trimester. Thus, whether earlier and stricter clinical intervention was necessary remained to be further studied. Furthermore, future studies will need to supplement the effects of blood glucose levels on GLS, FAC, GSI, and 24-segment SI. Additionally, the long-term follow-up after birth should also be improved to observe the influence of changes in the indicators on the prognosis.

Background. The behaviour of isobaric levobupivacaine in relation to gravity when used in obstetric spinal anesthesia is unclear.Methods. 46 women with ASA physical status 1 undergoing cesarean section were randomly allocated to 2 groups. Spinal anesthesia with 12.5 mg levobupivacaine was performed in the sitting position in all women. Those in the first group were placed in the supine position immediately after the injection, while those in the second group were asked to remain seated for 2 minutes before assuming the supine position. The sensory block level, the onset of sensory and motor blocks, the regression of the sensory block for 2 dermatomes of the sensory block, the first request for analgesics, and the regression of motor block were recorded.Results. No differences in onset times, sensory level, or Bromage score were observed between the two groups. The time of first analgesic request was earlier in the seated group (supine131±42 min, seated106±29 min,P=.02).Conclusion. Isobaric levobupivacaine in women at term produces a subarachnoid block the dermatomal level of which does not depend on gravitational forces.

Background: Dysregulation of placental mechanistic target of rapamycin (mTOR) activity has been implicated in the pathophysiology of pregnancies complicated by idiopathic fetal growth restriction (FGR) and gestational diabetes mellitus (GDM) with large-for-gestational-age (LGA) infants. However, the underlying mechanisms remain unclear.Methods: We obtained placentas from women with normal pregnancies (n = 11) and pregnancies complicated by FGR (n = 12) or GDM with LGA infants (n = 12) to compare the levels of total and phosphorylated forms of Akt, AMPK, TSC2, and mTOR among the three groups and used primary cytotrophoblast cells isolated from 30 normal term placentas to study the effects of oxygen–glucose deprivation (OGD) and increasing glucose concentrations on the changes of these factors in vitro.Results: Placentas from FGR pregnancies had lower phosphorylated Akt (p-Akt) levels (P &lt; 0.05), higher p-AMPKα levels (P &lt; 0.01), and lower mTOR phosphorylation (P &lt; 0.05) compared to that of normal pregnant women. Conversely, women with GDM and LGA infants had higher p-Akt (P &lt; 0.001), lower p-AMPKα (P &lt; 0.05), and higher p-mTOR levels (P &lt; 0.05) in the placentas than normal pregnant women. Furthermore, primary cytotrophoblast cells subjected to OGD had lower p-Akt and p-mTOR (both P &lt; 0.05) and higher p-AMPKα levels (P &lt; 0.05) than those cultured under standard conditions, but increasing glucose concentrations had opposite effects on the respective levels. Administering compound C, an AMPK inhibitor, did not significantly affect Akt phosphorylation but partially reversed mTOR phosphorylation. Administering LY294002, an Akt inhibitor, decreased p-mTOR levels, but did not change the levels of total and phosphorylated AMPKα.Conclusion: These results suggest that Akt and AMPK are involved in the regulation of trophoblast mTOR activity in the placentas of pregnancies complicated by FGR and GDM with LGA infants.

Abstract Objective To develop and validate a nomogram to better predict the vaginal birth after cesarean (VBAC) on the premise of clinical guide application. Methods We retrospectively identified hospitalised pregnant women who trial of labor after cesarean (TOLAC) between October 2015 and October 2017 using data from the Fujian Provincial Maternity and Children's Hospital. The inclusion criteria were as follows: Singleton pregnant women whose gestational age was above 37 weeks and underwent a primary cesarean section. Sociodemographic data and Clinical Characteristics were extracted. The samples were randomly divided into a training set and a validation set. Least absolute shrinkage and selection operator (LASSO) regression were used to select variables and construct of VBAC success rate in training set. The validation of the nomogram was performed using the concordance index (C-index), decision curve analysis (DCA), and calibration curves in the validation set. For comparison with published VBAC prediction models, the Grobman’s model was used. Results Among the 708 pregnant women included according to inclusion criteria, 586 (82.77%) patients were successfully for VBAC. In multivariate logistic regression models, Maternal height (OR, 1.11; 95% CI, 1.04 to 1.19), maternal BMI at delivery (OR, 0.89; 95% CI, 0.79 to 1.00), fundal height (OR, 0.71; 95% CI, 0.58 to 0.88), cervix Bishop score (OR, 3.27; 95% CI, 2.49 to 4.45), maternal age at delivery (OR, 0.90; 95% CI, 0.82 to 0.98), gestational age (OR, 0.33; 95% CI, 0.17 to 0.62) and history of vaginal delivery (OR, 2.92; 95% CI, 1.42 to 6.48) were independently associated with successful VBAC. The predictive model was constructed showed better discrimination in the validation series than Grobman’s model (c-index 0.906 VS 0.694, respectively). Decision curve analysis revealed that the new model resulted in a better clinical net benefit than the Grobman’s model. Conclusions The promotion of VBAC is helpful to reduce the cesarean section rate in China. On the basis of following the clinical practice guidelines, the TOLAC prediction model helps to improve the success rate of VBAC and has a potential contribution to the reduction of secondary cesarean section.

Background: To study the prevalence of gestational diabetes mellitus among antenatal mothers and to assess the importance of universal screening to detect gestational diabetes mellitus (GDM).Methods: A total of 300 antenatal women irrespective of gestational age were screened for GDM at their antenatal visit during the period of January 2020 to June 2020. All women were screened with 75gm oral glucose load irrespective of last meal followed by blood glucose estimation by glucose oxidase peroxidase method 2 hours following glucose load. A cut-off of 140mg/dl or more were labelled as gestational diabetes mellitus as per DIPSI guidelines.Results: Out of 300 antenatal women tested, 24 women (8%) were positive for gestational diabetes mellitus. During the first, second and third trimesters 12.5%, 33.33% and 54.17% were diagnosed with gestational diabetes mellitus respectively. The number of gestational diabetes mellitus patients for the age groups ≤20 years, 21-25 years, 26-30 years and >30 years are 2 (8.33%), 3 (12.5%), 8 (33.33%) and 11 (45.83%) respectively. The number of pregnant women tested positive for gestational diabetes mellitus with BMI ≤18.5, 18.6-24.9, 25-29.9 and 30-35 are 2 (8.33%), 4(16.67%), 8(33.33%) and 10(41.67%) respectively.Conclusions: Prevalence of GDM in our study is 8%. About 29.16% of GDM did not have any risk factors. This emphasizes the importance of universal screening for GDM of all pregnant women irrespective of gestational age. There is an increased association of GDM with age, BMI, family history and parity according to our study.
