Influence of non-pharmacological obstetric interventions on adverse outcomes of childbirth under regional analgesia.

Background We examined the influence of companionship and the use of complementary therapies on adverse outcomes in parturients under regional analgesia. Methods This study is a single-center retrospective cohort of 986 term pregnant women, and it was based on data from medical records (hospitalization period: November 2012-November 2018). The women were in the active phase of labor under regional analgesia. A statistical program was used to search for an association between companionship and the use of complementary therapies with sample data. Bi- and multivariate logistic regressions based on significant associations were used to analyze the potential intervening variables in the adverse outcomes. Results Models were constructed for each of the maternal adverse outcomes. Childbirth complications were significantly associated with complementary therapies [adjusted odds ratio (AOR) = 0.42; 95% confidence interval (CI) = 0.28-0.63; P < 0.001] and companionship (AOR = 0.36; 95% CI = 0.22-0.57; P < 0.001). Prolonged maternal hospitalization was significantly associated with companionship (AOR = 0.57; 95% CI = 0.36-0.92; P < 0.05). Unplanned cesarean section showed a significant association with complementary therapies (AOR = 0.05; 95% CI = 0.01-0.47; P < 0.01). Conclusion The likelihood of childbirth complications and prolonged maternal hospitalization is reduced by companionship, whereas the likelihood of childbirth complications and cesarean section rates is reduced by the use of complementary therapies.

Anesthesia for Nonobstetric Surgery During Pregnancy in a Tertiary Referral Center: A 16-Year Retrospective, Matched Case-Control, Cohort Study

(Int J Obstet Anesth. 2019;39:74–81) Nonobstetric operative interventions during pregnancy are fairly uncommon, but can increase the risk of preterm delivery, low birth weight, and cesarean delivery. There has been limited research conducted on the pregnancy outcomes of women who undergo nonobstetric surgical procedures. These investigators, therefore, conducted this retrospective analysis to compare pregnancy outcomes in parturients who underwent nonobstetric surgical procedures to their hospital’s entire obstetric patient population as well as to a matched case-control cohort based on similar demographics.

Gestational diabetes mellitus: the correlation between umbilical coiling index, and intrapartum as well as neonatal outcomes.

The objective of this study was to investigate the relationship between the postnatal umbilical coiling index (pUCI), and intrapartum and neonatal outcomes in parturients with gestational diabetes mellitus (GDM) and non-GDM. An evaluation of the umbilical cords and pUCI of 117 neonates of GDM and 105 of non-GDM parturients were prospectively studied within 24h after delivery. Furthermore, obstetric history, intrapartum and neonatal data were recorded. Premature rupture of membrane (PROM) (p = 0.001), emergency cesarean delivery (p = 0.01), spontaneous preterm delivery (p = 0.006), duration of hospital admission (p < 0.001), and congenital malformations (p = 0.03) were significantly higher in the GDM group. Moreover, pUCI had a significant association with large for gestational age (LGA) (p = 0.009), and meconium-stained amniotic fluid (p = 0.04) in the GDM group. In addition, increment of pUCI had significant association with spontaneous preterm delivery in both groups (p = 0.002) (OR = 1.23). GDM is associated with spontaneous preterm delivery, PROM, emergency cesarean delivery, duration of hospital admission, and congenital malformations. Increase in pUCI could increase the rate of spontaneous preterm delivery in normal pregnancy and pregnancy complicated by GDM, as well as, the rate of LGA and meconium-stained amniotic fluid in GDM.

Clinical characteristics and pregnancy outcomes in parturients with pulmonary hypertension: experience with 39 consecutive cases from China

Purpose: The authors aimed to understand the clinical characteristics of pulmonary hypertension (PH) with pregnancy and pregnancy outcomes in Chinese population. Materials and Methods: The authors retrospectively analyzed 39 parturients with PH. The patients were divided into mild PH group (n = 20) and severe PH group (n = 19). They compared some clinical characteristics, as well as maternal and fetal outcomes between the mild and severe PH groups. Results: The diagnostic rate of PH before pregnancy was 7.7% and the overall maternal mortality was 15.4%. There was no significant difference in age, body mass index, average termination of gestation weeks, and New York Heart Association functional class pre-pregnancy between the mild and severe PH groups. The mortality in the severe PH group (31.6%) was significantly higher than that in the mild PH group (0%) (p p Conclusion: The overall mortality of parturients with PH is high and severe PH increase the risk of death, occurrence rate of PPH, and natality of LBWN.

Retrospective analysis of anesthetic and perioperative management in patients of acute fatty liver of pregnancy

Objective: To retrospectively analyze the clinical characteristics of patients with acute fatty liver of pregnancy (AFLP), and to discuss perioperative and anesthetic management. Methods: A retrospective review was conducted on the records of pregnant patients with a diagnosis of acute fatty liver of pregnancy in Peking University Third Hospital from January 2007 to December 2015. 12 cases were identified. The clinical features, preoperative laboratory findings, types of delivery, anesthetic techniques for cesarean section, and the outcomes of parturients and fetus were collected and analyzed. Results: Among the 12 cases, 91.7% were primigravid, 50% had twin pregnancies, and one was diagnosed with concomitant preeclampsia. The common clinical features included nausea (6 cases, 54.5%), vomiting (5 cases, 45.5%), jaundice (5 cases, 45.5%), malaise (3 cases, 27.3%), epigastric discomfort (2 cases, 18.2%), anorexia (2 cases, 18.2%) and regurgitation (1 case, 9.1%). Laboratory tests mainly showed impaired hepatic function and hypoglycemia. Cesarean deliveries were performed in 10 of the 11 patients diagnosed antepartum. Cesarean section was performed under neuraxial anesthesia (1 case) or general anesthesia (9 cases). The patient transferred to our center after delivery and diagnosed postpartum died. All the patients diagnosed antepartum survived. 6 out of the 18 fetuses were transferred to the pediatric department due to preterm, low birth weight, intrauterine restriction or asphyxiation, and were all survived. Conclusions: AFLP is one of the most severe complications in parturients. Prognosis can be improved with early diagnosis and prompt termination of pregnancy. Hepatic function, coagulation status and urgency of delivery should be well considered to choose the appropriate anesthetic method, and anesthetic management should be individualized.

A Prospective Randomized Trial of Postural Changes vs Passive Supine Lying during the Second Stage of Labor under Epidural Analgesia.

There exist very few studies comparing different postures or postural changes during labor in parturients with epidural analgesia. Aim: To disclose whether the intervention of a multidisciplinary nursing team including a physiotherapist during the second stage of labor improves the obstetric outcome in parturients with epidural analgesia. Design: Prospective randomized trial. Setting: University-affiliated hospital. Population: Women undergoing labor with epidural analgesia after a normal gestation. Methods: 150 women were randomized either to actively perform predefined postural changes during the passive phase of the second stage of labor under the guidance of the attending physiotherapist (study group), or to carry out the whole second stage of labor lying in the traditional supine position (control group). Results: There were significantly more eutocic deliveries (p = 0.005) and, conversely, significantly less instrumental deliveries (p < 0.05) and cesarean sections (p < 0.05) in the study group. The total duration of the second stage of labor was significantly shorter (p < 0.01) in the study group. This was at the expense of the passive phase of the second stage of labor (p < 0.01). Significantly less episiotomies were performed in the study group (31.2% vs 17.8%, p < 0.05). Conclusion: The intervention of a physiotherapist during the second stage of labor significantly improved the obstetric outcome.

Retrospective analysis of maternal, fetal, and neonatal outcomesof intrahepatic cholestasis of pregnancy at Gazi University.

Maternal, fetal, and neonatal outcomes in parturients with intrahepatic cholestasis of pregnancy (ICP) have been retrospectively documented. We aimed to present pregnancy outcomes of parturients with ICP who underwent delivery. The study was conducted during a 1-year period. After ethics committee approval, data from 1 January to 31 December 2015 were collected to identify parturients with ICP. Ten out of 37 patients underwent normal spontaneous vaginal delivery (NSVD), and the remaining 27 parturients underwent cesarean section (CS). Five of 27 parturients underwent nonelective cesarean section, while 22 had elective cesarean delivery. As for NSVD deliveries, only one parturient received combined spinal and epidural anesthesia (CSE) for labor. Neuraxial (n = 22 for spinal and n = 1 for CSE) and general anesthesia (n = 4) rates for CSs were 85% and 15%, respectively. Approximately 96% of neuraxial anesthesia choices were spinal anesthesia. Nearly 18.5% of CSs were not elective. Adverse outcomes included 2 preterm births, 2 preterm labors, 2 newborns with hepatitis, and one perinatal fetal death. Parturients with ICP who had normal coagulation parameters despite increased liver enzymes preoperatively underwent cesarean delivery under spinal anesthesia without complication. Although maternal outcomes were generally positive, adverse fetal and neonatal outcomes are more likely to occur, particularly in cases with severe ICP.

Prosthetic Heart Valves in Pregnancy, Outcomes for Women and their Babies: A Systematic Review and Meta-analysis

(BJOG. 2015;122(11):1446–1455) An increased incidence of adverse outcomes (maternal mortality, miscarriage, thromboembolism, and obstetric hemorrhage) has been reported among pregnant women with prosthetic heart valves. Infants born to these women are also at increased risk of perinatal mortality, preterm birth, small-for-gestational-age, and congenital malformations. There have been advances in prosthetic heart valve design and medical care, leading to improved outcomes for patients with prosthetic valves. Review of the available data on recent outcomes in parturients with prosthetic heart valves is therefore required. The primary objective of this systematic review was to assess the risk of an adverse outcome in pregnant women with prosthetic heart valve(s) over the last 20 years (1995 to 2014). Absolute risk of adverse outcomes by prosthetic type and/or location was also evaluated as a secondary objective.

Combined spinal-epidural analgesia in labour: its effects on delivery outcome

Combined spinal-epidural (CSE) has become an increasingly popular alternative to traditional labour epidural due to its rapid onset and reliable analgesia provided. This was a prospective, convenient sampling study to determine the effects of CSE analgesia on labour outcome. One hundred and ten healthy primigravida parturients with a singleton pregnancy of ≥37 weeks gestation and in the active phase of labour were studied. They were enrolled to the CSE (n=55) or Non-CSE (n=55) group based on whether they consented to CSE analgesia. Non-CSE parturients were offered other methods of labour analgesia. The duration of the first and second stage of labour, rate of instrumental vaginal delivery and emergency cesarean section, and Apgar scores were compared. The mean duration of the first and second stage of labour was not significantly different between both groups. Instrumental delivery rates between the groups were not significantly different (CSE group, 11% versus Non-CSE group, 16%). The slightly higher incidence of cesarean section in the CSE group (16% versus 15% in the Non-CSE group) was not statistically significant. Neonatal outcome in terms of Apgar score of less than 7 at 1 and 5min was similar in both groups. There were no significant differences in the duration of labour, rate of instrumental vaginal delivery and emergency cesarean section, and neonatal outcome in parturients who received compared to those who did not receive CSE for labour analgesia.

Effect of neuraxial technique after inadvertent dural puncture on obstetric outcomes and anesthetic complications

BackgroundThe aim of this study was to evaluate labor and delivery outcomes in parturients with inadvertent dural puncture managed by either insertion of an intrathecal catheter or a resited epidural catheter. MethodsThis was a retrospective cohort review of 235 parturients who had an inadvertent dural puncture during epidural placement over a six-year period. The primary outcome was the proportion of women with a delayed second stage of labor. Secondary outcomes were the proportion of cesarean deliveries, the proportion of cases resulting in post-dural puncture headache, and the incidence of failed labor analgesia. ResultsBaseline characteristics such as age, body mass index and parity were similar between the two groups. Among the 236 cases of inadvertent dural puncture, 173 women (73%) had an intrathecal catheter placed while 63 women (27%) had the epidural catheter resited. Comparing intrathecal with epidural catheters, there was no observed difference in the proportion of cases of prolonged second stage of labor (13% vs. 16%, P=0.57) and the overall rate of cesarean deliveries (17% vs. 16%, P=0.78). However, we observed a lower rate of post-dural puncture headache in women who had cesarean delivery compared to vaginal delivery (53% vs. 74%, P=0.007). A greater proportion of failed labor analgesia was observed in the intrathecal catheter group (14% vs. 2%, P=0.005). ConclusionThe choice of neuraxial technique following inadvertent dural puncture does not appear to alter the course of labor and delivery. Cesarean delivery decreased the incidence of post-dural puncture headache by 35%. Intrathecal catheters were associated with a higher rate of failed analgesia.

Anesthetic management and outcomes of parturients with dilated cardiomyopathy in an academic centre.

This study examines the peripartum anesthetic management and outcomes of women with dilated cardiomyopathy in a large university medical centre over a seven-year period. Twenty-five women were included in this series, 18 with a new diagnosis of cardiomyopathy and seven with a history of cardiomyopathy. Sixteen patients (64%) identified themselves as African American, seven (28%) were Caucasian, and two patients (8%) were Hispanic. The median (range) gestational age at the time of a new diagnosis of cardiomyopathy was 29 (7-38) weeks. Eight women (32%) had New York Heart Association class III/IV symptoms at the time of delivery or in the immediate postpartum period. A multidisciplinary team of obstetricians, anesthesiologists, cardiologists, and pediatricians were involved in the care of these women. The median (range) gestational age at the time of delivery was 33.5 (30-40) weeks. There were nine vaginal deliveries and 15 operative deliveries. One patient had fetal loss at 19weeks gestation. Twelve women had labour induced with an intravenous infusion of oxytocin at a rate of 0.001-0.02IU·min(-1). An oxytocin infusion at a variable rate with a maximum dose of 0.05IU·min(-1) was administered after vaginal delivery to maintain uterine tone. Epidural analgesia was initiated prior to induction of labour or in the latent phase of labour. Seven Cesarean deliveries were performed under combined spinal-epidural anesthesia, five were performed under epidural anesthesia, and three women had general anesthesia. Oxytocin was administered via an intravenous infusion at a rate of 0.05-0.2IU·min(-1) after operative delivery. One patient had a cardiac arrest on induction of general anesthesia and was successfully resuscitated. There were no maternal or neonatal deaths. Ten women were followed up at our institution and at six months postpartum; 50% of these patients were still symptomatic. We report favourable outcomes in 25 pregnant women with dilated cardiomyopathy who were managed by a multidisciplinary team.

Thrombocytopenia in pregnancy: do the time of diagnosis and delivery route affect pregnancy outcome in parturients with idiopathic thrombocytopenic purpura?

The objective of this study was to investigate the determining effects of diagnosis time on pregnancy outcomes in a population of pregnant women with idiopathic thrombocytopenic purpura (ITP). Records of all the pregnant women with thrombocytopenia were evaluated. Those with a confirmed diagnosis of ITP were included in the study. Main outcome measures were antenatal thrombocyte count, postpartum haemorrhage rate, and route of delivery. Foetal outcomes such as foetal thrombocyte count, haemorrhage, and birth weight were also reported as secondary outcome measures. Time of diagnosis either antenatal or preconception did not significantly alter the investigated parameters. Delivery route had no impact on complication rates. Time of diagnosis also did not affect treatment modality. ITP is rare disorder accounting for less than 5 % of all pregnant thrombocytopenias. Time of diagnosis does not affect maternal-foetal outcomes or treatment modality unless diagnosis is made during labour. Compared to gestational thrombocytopenia, treatment rates may differ but treatment modalities remain the same and the effort put into making the differential should be weighed against maternal stress factors for lengthy laboratory evaluation as long as the thrombocytopenia is of pure nature without any systemic involvement.

Cervical Pessaries for Prevention of Preterm Birth in Women With a Multiple Pregnancy (ProTWIN)

Women with multiple gestations often deliver at less than 37 weeks, increasing the risks of perinatal morbidity and mortality. Treatment with a pessary might prevent preterm birth by changing the inclination of the cervical canal and preventing premature dilatation of the cervix, rupture of the membranes, and deterioration or loss of the cervical mucous plug. This multicenter, open-label, randomized controlled trial at 40 hospitals was performed to determine whether a cervical pessary could prevent poor perinatal outcomes in parturients with a multiple pregnancy. At 12 to 20 weeks' gestation, patients were assigned to the pessary or control group; cervical length was measured at 16 to 22 weeks. Women in the study group received an Arabin pessary at 16 to 20 weeks, which was removed in week 36 or in case of preterm premature rupture of the membranes, active vaginal bleeding, other signs of preterm labor, or patient discomfort. Obstetric care was otherwise similar in the 2 groups. The primary outcome was a composite of poor perinatal outcomes, including stillbirth, preventricular leukomalacia, severe respiratory distress syndrome, bronchopulmonary dysplasia, intraventricular hemorrhage, necrotizing enterocolitis, sepsis, and neonatal death within 6 weeks after the anticipated term date. Secondary outcomes were time to delivery, preterm birth at less than 32 and less than 37 weeks, days in the neonatal intensive care unit, days of maternal admission for preterm labor, and maternal morbidity. A total of 401 of 403 women in the pessary group and 407 of 410 in the control group completed the study. Five women in the pessary group had a surgical cerclage; 1 patient died, and the others delivered at 21.6 to 36.7 weeks, with 3 having poor perinatal outcomes. No patients in the control group had a cerclage. Vaginal discharge occurred in 104 women (26%) in the pessary group and in none of the controls. The pessary was removed from 57 women (14%) at less than 28 weeks and from 22 women (5%) at 28 to 32 weeks; 7 and 13, respectively, delivered within 48 hours of removal. At 32 to 36 weeks, the pessary was removed from 107 women; 70 delivered within 48 hours. The most common reasons for pessary removal in these women were preterm premature rupture of the membranes, vaginal bleeding, contractions, and induction of labor. The composite poor perinatal outcome occurred in 53 women (13%) and 55 women (14%) in the pessary and control groups, respectively (relative risk (RR), 0.98; 95% confidence interval, 0.69-1.39). Ten stillbirths (2%) occurred in each group. The other conditions within the composite outcome did not differ between the 2 groups. In the pessary and control groups, 16 and 18 infants, respectively, died before discharge. The groups were similar in median gestational age at delivery; frequencies of delivery at less than 28, less than 32, and less than 37 weeks; and frequency and length of neonatal intensive care unit admission. In the women with a cervical length of less than 25th percentile (

Peripartum anesthetic management of patients with Factor XI deficiency

Factor XI deficiency is predominantly found in the Ashkenazi Jewish population with a prevalence of 9%, but also seen in other ethnicities. Little information is available on obstetric anesthesia management in women with Factor XI deficiency. Therefore, we undertook a study to evaluate obstetric, anesthetic and perinatal outcomes in parturients with Factor XI deficiency. A retrospective study was conducted with chart reviews from 1996 to 2011 resulted in 74 women with Factor XI level deficiency. We compared anesthetic and obstetric management in parturients with low (≤30%) level of Factor XI to those with higher levels. Ninety-one pregnancy outcomes were reviewed in these 74 women with Factor XI deficiency. Forty-three women had levels ≤30% in 46 labors while 31 women had levels >30% in 45 labors. Women with low levels of Factor XI were significantly more likely to receive FFP and less likely to receive neuroaxial anesthesia. There were no anesthetic complications and no difference in mode of delivery or neonatal outcomes. This study is the first step in building a national database for anesthetic cases and outcomes of parturients with Factor XI deficiency. Further efforts must be made to provide safe analgesia for these women.

Blood transfusion trends in obstetrics at the Federal Teaching Hospital in Abakaliki, South-East Nigeria

BackgroundObstetric hemorrhage has been repeatedly implicated as a leading cause of maternal mortality in Nigeria, yet there are very few studies that evaluate the practice of blood transfusion in obstetrics as a life saving measure.ObjectivesThe aim of this study was to evaluate the practice of obstetric blood transfusion, the mean decision-transfusion interval, and the outcome in parturients who had blood transfusions.MethodsThis was a prospective descriptive study conducted at the Federal Teaching Hospital, Abakaliki, South-East Nigeria, between 1st January, 2012 and 31st December, 2012. Statistical analysis was done using SPSS version 15.0 for Windows.ResultsOut of 151 parturients who received blood transfusion, 141/151 (97.4%) were knowledgeable about blood transfusion, while only 10/151 (2.6%) had no knowledge of it. The hospital was the source of information for 120/151 (80.8%) of the participants. Blood transfusion rate was 7.04% of all parturients. The mean decision-transfusion interval was 12.0 ± 4.3 hours. All participants were transfused with either whole blood or sedimented cells. The mean number of blood units transfused was 1.77 ± 0.93 units. The indications for transfusion were: anemia, 109/151 (72.2%); shock, 13/151 (8.6%); postpartum hemorrhage, 23/151 (15.2%); antepartum hemorrhage, 6 (4%). Six (4%) women died; mortality was due to renal failure in 3/6 (50%) and disseminated intravascular coagulopathy in 3/6 (50%). These deaths were due to delays and difficulty in securing blood for transfusion, while those who got transfused on time were salvaged with minimal morbidity, 21/151 (14%), or with no morbidity, 130/151 (86%).ConclusionExcessive blood loss and anemia still complicate most pregnancies in our practice and the mean decision-transfusion interval is unacceptably long with debilitating maternal morbidity and mortality that can be improved with safe and effective blood transfusion with minimal or no risk.

Obstetric anaesthesia outcome in obese and non-obese parturients undergoing caesarean delivery: an observational study

Background Maternal obesity is increasing in prevalence and is associated with an increased risk of perioperative complications. This study evaluates the impact of obesity on perioperative outcomes in parturients undergoing caesarean delivery. Methods In this prospective observational study of 1477 consecutive caesarean deliveries, data collected included body mass index, co-morbidities, anaesthetic technique, perioperative complications and patient satisfaction. Outcome measures included obesity prevalence, association of obesity with caesarean delivery, co-morbidities, perioperative complications and patient satisfaction and were compared between the obese and non-obese groups. Results The prevalence of obesity was 54.3%, including 7.2% morbidly obese. About 61% of parturients who underwent caesarean delivery because of failure to progress in labour or previous caesarean were obese. The overall prevalence of co-morbidity was 10.2% of whom 57.3% were obese. Neuraxial anaesthesia was used in 73.4% and general anaesthesia in 26.6%, similar in obese and non-obese. The epidural failure rate was 4.3% and the spinal failure rate 2.9%. Difficulty in performing neuraxial anaesthesia was greater in obese patients ( P = 0.004). There was no association between obesity and laryngoscopy grades. Patient satisfaction was similar in the obese and non-obese groups. Postoperative complications were minimal and similar. Conclusions Neuraxial anaesthesia was effective for caesarean deliveries in obese and non-obese, in elective and emergency cases. Maternal obesity is associated with increased difficulty in performing neuraxial anaesthesia, but not with increased failure rate. Our study found no differences between obese and non-obese parturients in rate of caesarean deliveries, co-morbidities, indications for delivery or anaesthesia complications.

Has there been any progress made on pregnancy outcomes among women with pulmonary arterial hypertension?

Pregnancy in women with pulmonary arterial hypertension (PAH) is considered to be associated with prohibitive maternal mortality. During the past decade, new advanced therapies for PAH have emerged and progress in high-risk pregnancy management has been made. We examined whether these changes have improved outcomes in parturients with PAH. A systematic review of all cases of parturients with idiopathic pulmonary hypertension (iPAH), congenital heart disease associated with PAH (CHD-PAH), or PAH of other aetiology (oPH) published in the past decade (1997-2007) was performed. Outcome data from this study were then compared with relevant data published between 1978 and 1996. Forty-eight case reports or case series met the inclusion criteria, totalling 73 parturients with PAH. Seventy-two per cent of patients with iPAH were receiving advanced therapies, compared with 52% of CHD-PAH and 47% of oPH. Although a publication bias cannot be excluded, overall maternal mortality was significantly lower compared with previous era (25 vs. 38%, P = 0.047) and was 17% in iPAH, 28% in CHD-PAH, and 33% in oPH. Seventy-eight per cent of deaths occurred within the first month after delivery. Primigravidae and parturients who received general anaesthesia were at higher risk of death (OR 3.70, 95% CI 1.15-12.5, P = 0.03 and OR 4.37, 95% CI 1.28-16.50, P = 0.02, respectively). Maternal mortality in parturients with PAH remains prohibitively high, despite lower death rates than previous decades. Early advice on pregnancy risks, including contraception, remains paramount. Women with PAH who become pregnant warrant a multidisciplinary approach with consideration of advanced therapies.
