The effect of intraspinal blocking analgesia on delivery quality and puerperal pelvic floor function of primipara / 中国医师进修杂志

Objective:To explore the effects of intraspinal blocking analgesia on the delivery quality and puerperal pelvic floor function of primiparas.Methods:A total of 99 primiparas who delivered in the Second People′s Hospital of Wuhu City from January 2021 to April 2022 were enrolled in this study, 54 patients received intraspinal blocking analgesia (study group) and 45 patients received conventional treatment, without intraspinal blocking analgesia (control group). The delivery quality between the two groups was compared, and the pelvic floor function was evaluated and compared by pelvic floor rehabilitation therapy instrument and pelvic floor ultrasound at 6-8 weeks after delivery.Results:Vaginal delivery were successful in both groups. The total labor duration in the study group was longer than that in the control group: (8.03 ± 2.94) h vs. (6.89 ± 3.49) h, there was statistical difference ( P<0.05). The maximum value of pelvic floor rapid contraction stage, rising time and average value of continuous contraction stage in the study group were higher than those in the control group: (32.85 ± 10.13) μV vs. (14.73 ± 3.25) μV, (0.28 ± 0.06) s vs. (0.22 ± 0.05) s, (30.26 ± 5.24) μV vs. (16.74 ± 4.00) μV, there were statistical differences ( P<0.05). There were no statistical differences in other indicators such as the pre-resting stage, rapid contraction phase recovery time and post-resting stage between the two groups ( P>0.05). The rate of pelvic floor class Ⅰ and class Ⅱ muscle abnormalities at 6-8 weeks after delivery in the study group were lower than those in the control group, but there were no statistical differences ( P>0.05). The maximum Valsalva state hiatus area of levator ani muscle, maximum Valsalva state bladder posterior urethral angle, hiatus area of levator ani muscle at rest state and bladder neck degree in the study group were smaller than those in the control group: (19.09 ± 4.82) cm 2 vs. (23.00 ± 5.34) cm 2, (138.59 ± 23.14)° vs. (148.47 ± 20.38)°, (9.96 ± 2.63) cm 2 vs. (11.60 ± 2.75) cm 2, (20.13 ± 4.37) mm vs. (28.05 ± 6.52) mm, there were statistical differences ( P<0.05). Conclusions:Although intraspinal block analgesia can prolong the total labor time of primipara, but it can reduce the damage of pelvic floor function, possibly by increasing systolic period to protect pelvic floor muscles.

Construction and application of prenatal health education curriculum based on virtual simulation technology / 中华护理杂志

Objective To construct,implement and evaluate the effectiveness of the virtual simulation technology-based prenatal health education course.Methods The curriculum included 4 parts:"warm delivery room and easy delivery","medicated analgesic delivery","non-medicated analgesic delivery"and"early maternal and infant health care".From May to September 2022,100 primiparas in an obstetrics and gynecology hospital in Zhejiang Province were investigated by convenient sampling method.Random number table method was used to divide the participants into an experimental group and a control group,with 50 participants per group.The control group received conventional health education,while the experimental group received an augmented virtual reality technology-based prenatal health education course during the late stages of pregnancy on this basis.We conducted a post-intervention comparative analysis of antenatal anxiety levels,fear of childbirth,and birth outcomes between the 2 groups.Furthermore,a post-intervention satisfaction survey was administered to the experimental group.Results After intervention,the antenatal anxiety of the experimental group was lower than that of the control group(x2=4.943,P=0.026),and the decrease in fear of childbirth scores was higher than that of the control group(t=3.200,P=0.002).The experimental group was highly satisfied with all of the 4 dimensions of the course,and the overall evaluation was(31.8±3.23)points.However,there were no significant differences in vaginal delivery rate,postpartum bleeding volume,postpartum hemorrhage incidence,perineal injury degree and duration of each labor stage between the 2 groups(P＞0.05).Conclusion The virtual reality technology-based prenatal health education course was effective in improving the antenatal anxiety and fear of childbirth of primipara,and the use satisfaction is high.

Effects of epidural labor analgesia on early neonatal sucking and breastfeeding / 中华围产医学杂志

Objective:To investigate the effects of epidural labor analgesia on neonatal sucking ability and breastfeeding.Methods:This was a prospective cohort study. Convenience sampling was used to enroll women who delivered with or without epidural analgesia (epidural analgesia and non-analgesia groups) in the Affiliated Maternity and Child Health Care Hospital of Nantong University from January 2022 to December 2022. Intra-oral negative pressure values during breastfeeding were measured by a pressure measuring instrument within 3 d after birth (0-24 h, >24-48 h, and >48-72 h), and the mean, maximum, and minimum pressure values were recorded. The Infant Breastfeeding Assessment Tool (IBAT) (Chinese version) was used to evaluate sucking posture. Breastfeeding status during hospitalization and within 1, 4, and 6 months after discharge were followed up. Two independent samples t-test, Chi-square (Fisher's exact) test, and generalized estimating equations were used for data analysis. Results:A total of 156 mother-infant pairs were analyzed in this study, with 78 pairs in the epidural analgesia group and 78 pairs in the non-analgesia group. The whole, first, and second stages of labor were longer in the analgesia group than those in the non-analgesia group [ M( P25- P75), total: 430 min (353-541 min) vs. 300 min (235-422 min), Z=－5.65; first stage: 385 min (310-490 min) vs. 260 min (205-347 min), Z=－5.81; second stage: 40 min (26-67 min) vs. 33 min (18-45 min), Z=－2.33; all P<0.05], and more women in the analgesia group accepted oxytocin and doula before delivery [94.8% (74/78) vs. 43.6% (34/78), χ2=48.15; 42.3% (33/78) vs. 19.2% (15/78), χ2=9.75; both P<0.05]. There was no significant difference in scores on the Fatigue Scale-14, Edinburgh Postnatal Depression Scale, Pittsburgh Sleep Quality Index, and Life Events Scale for Pregnant Women between the two groups. After adjusting for confounding factors by generalized estimating equations, the mean intra-oral negative pressure values in the epidural analgesia group were lower than those in the non-analgesia group at 0-24 h, >24-48 h, and >48-72 h after birth [5.14 (3.39-6.52) vs. 6.39 (4.95-9.15) kPa, 5.07 (3.94-7.38) vs. 6.20 (5.08-8.54) kPa, and 6.19 (4.64-8.36) vs. 6.81 (5.88-8.05) kPa, Wald χ2=5.59, P=0.018]; the peak value in the epidural analgesia group was also lower than that in the non-analgesia group [15.81 (9.74-21.68) vs. 16.21 (13.58- 24.88) kPa, 13.50 (9.83-16.50) vs. 17.62 (14.01-22.40) kPa, and 14.66 (10.47-18.71) vs. 18.04 (15.33- 19.85) kPa, Wald χ2=7.25, P=0.007]; there were no significant differences in the trough value between the two groups. The daily IBAT scores for the sucking position of neonates in the epidural analgesia group were all lower than those in the non-analgesia group in the first three days after delivery [10 (9-10) vs. 10 (10- 11) scores, 10 (9-11) vs. 11 (10-11) scores, and 10 (10-11) vs. 11 (11-12) scores, Wald χ2=17.05, P=0.001]. The rates of early exclusive breastfeeding within postpartum 3 d were also lower in the epidural analgesia group than those in the non-analgesia group [67.9% (53/78) vs. 75.6% (59/78), 41.0% (32/78) vs. 44.9% (35/78), and 38.5% (30/78) vs. 55.1% (43/78), Wald χ2=4.21, P=0.040]. No significant differences were found in the exclusive breastfeeding rates between the two groups at 1, 4, and 6 months after delivery. Conclusion:Epidural labor analgesia can lead to decreased early intra-oral negative pressure in neonates, affect neonatal sucking posture, and reduce the rate of exclusive breastfeeding during hospitalization, but has no significant correlation with the exclusive breastfeeding rate within six months after delivery.

Objective:To observe the clinical efficacy of pressing-kneading manipulation combined with herb-insulated moxibustion at Shuidao(ST28)for postpartum urinary retention after labor analgesia and its effect on bladder urination function. Methods:A total of 154 patients with postpartum urinary retention after labor analgesia were randomly divided into a Western medication group and a herb-insulated moxibustion group,with 77 cases in each group.In the Western medication group,neostigmine sulfate was injected into Zusanli(ST36).In the herb-insulated moxibustion group,after pressing-kneading manipulation at Shuidao(ST28),herb-insulated moxibustion was applied to Shuidao(ST28)with self-made Tong Quan San.Both groups were treated once,and the clinical efficacy was evaluated 5 h after treatment.The first urination time,first urination volume,average urinary flow rate,bladder residual urine volume,hospitalization days,and costs were recorded. Results:The total effective rate and markedly effective rate of the herb-insulated moxibustion group were higher than those of the Western medication group(P<0.05),the time to the first urination and residual urine volume in the bladder of the herb-insulated moxibustion group were shorter or smaller than those of the Western medication group(P<0.01),the first urination volume and average urine flow rate of the herb-insulated moxibustion group were larger than those of the Western medication group(P<0.01).There were no significant differences in the hospitalization days and costs between the two groups(P>0.05). Conclusion:Pressing-kneading manipulation combined with herb-insulated moxibustion at Shuidao(ST28)can effectively treat postpartum urinary retention after labor analgesia and improve bladder urination function.

Efficacy of different administration methods for labor analgesia / 中国基层医药

Objective:To investigate the clinical efficacy of different administration methods for labor analgesia.Methods:This randomized controlled study was conducted on 152 parturient women who underwent vaginal delivery at the Xinxiang Central Hospital from February to June 2023. These women were divided into a control group and an observation group, with 76 women per group. Women in the control group received 3 mL of 0.1% ropivacaine hydrochloride after routine epidural catheterization, followed by 3 mL of analgesic drugs after 3 minutes. For those without any special reactions, an analgesic pump containing 9 mL of medication was used after 3 minutes until the end of labor. In the observation group, 3 mL of 0.1% ropivacaine hydrochloride was administered as a trial dose before the epidural catheter was inserted into the epidural space. After 3 minutes, the postpartum woman lay flat and was given another 3 mL of analgesic pump medication. After 3 additional minutes, an additional 9 mL of the medication was administered. The analgesic pump was connected and turned on until the catheter was removed after delivery. The epidural catheter failure rate was assessed in each group. Before epidural puncture (T 1), within 30 minutes after the onset of anesthesia (T 2), and at the time of full dilation of the cervix (T 3), Visual Analogue Scale scores, the number of patient attempts to additionally use an analgesia pump, maternal satisfaction, the number of cases requiring cesarean section conversion, the incidence of adverse reactions (such as nausea, vomiting, and fever), and Apgar scores for newborns were recorded in each group. Results:The epidural catheter failure rate in the observation group was 1.3% (1/76), which was significantly lower than 10.5% (8/76) in the control group ( χ2 = 5.79, P < 0.05). At T 2 and T 3, the Visual Analogue Scale score in the observation group was (0.89 ± 0.08) points and (2.1 ± 0.07) points, respectively, which were significantly lower than (2.55 ± 0.07) points and (3.35 ± 0.07) points in the control group ( t = 238.54, 133.17, both P < 0.001). The number of patient attempts to additionally use an analgesia pump in the observation group was (1.00 ± 0.84) counts, which was significantly less than (4.00 ± 0.65) counts in the control group ( t = 29.47, P < 0.001). Maternal satisfaction in the observation group was 100% (76/76), which was significantly higher than 92.1% (70/76) in the control group ( χ2 = 6.25, P < 0.05). The number of cases requiring cesarean section conversion in the observation group was 0 (0/76), which was significantly lower than 52.6% (4/76) in the control group ( χ2 = 4.10, P < 0.05). Conclusion:Administering a trial dose (3 mL) of 0.1% ropivacaine hydrochloride before placing the epidural catheter during labor analgesia can greatly increase the placement success rate of the catheter and enhance pain relief effectiveness. This has a certain clinical application value.

Efficacy of enhanced epidural anesthesia in patients undergoing cesarean section: a single-center retrospective observational study / 中华麻醉学杂志

Objective:To retrospectively review the efficacy of enhanced epidural anesthesia in the patients undergoing cesarean section.Methods:The data from patients who underwent cesarean section in our hospital from August 2008 to December 2021 were retrospectively collected. The method of epidural anesthesia, drug dosage, onset time, blocking level, anesthesia effect, remedial medication, and complications related to the method were recorded. The main points of enhanced epidural anesthesia included: ① test negative pressure by rotating the epidural puncture needle in situ to determine the position of the needle tip; ② catheterization after administering local anesthetic through epidural puncture needle to assess the clinical application of this technique. A questionnaire survey was conducted in 134 anesthesiologists with qualifications for epidural procedures. The questionnaire addressed whether to perform routine needle rotation during epidural procedures, direction of needle rotation, and the percentage of the dosage of local anesthetic administered through puncture needle. Results:A total of 10 054 patients received epidural anesthesia (10 016 cases) and switched to general anesthesia because of poor epidural effect or intraoperative emergencies (38 cases) were enrolled. The consumption of local anesthetics for epidural anesthesia was 18 (15, 20) ml.There were 7 287 cases with block plane records, of which the ratio of the block level reached T 6-8 was 86.84%. The time from the beginning of anesthesia to skin incision was 25 (20, 30) min. Sixteen patients (0.159%) switched to general anesthesia because of poor epidural effect.Among 10 016 patients underwent epidural anesthesia, 925 patients (9.235%) received intravenous adjunctive drugs.No patients experienced total spinal anesthesia, 25 patients (0.248%) had epidural perforation due to puncture or needle rotation, and 4 cases (0.039%) local anesthetic intoxication, 3 cases (0.030%) postoperative nerve injury, and 142 patients (1.412%) requiring intervention with vasoactive drugs due to hemodynamic instability within 30 min after epidural administration. Questionnaire survey: The proportion of anesthesiologists rotating epidural puncture needles was 85.1%, and the proportion of anesthesiologists using epidural puncture needles to inject local anesthesia drugs with a dose greater than 50% of the total dose before catheterization was 84.2%. Conclusions:Enhanced epidural anesthesia can provide effective anesthesia for the patients undergoing cesarean section without increasing the risk of complications related to epidural procedures.

Effect of esmketamine for labor analgesia on development of postpartum depression / 中华麻醉学杂志

Objective:To evaluate the effect of esmketamine for labor analgesia on the occurrence of postpartum depression (PPD).Methods:Two hundred and forty-two cases of nulliparous parturients who selected natural labor and agreed to receive labor analgesia were selected and divided into conventional labor analgesia group (C-LA group, n=119) and esmketamine-based labor analgesia group (E-LA group, n=123). The epidural labor analgesia solution contained ropivacaine 100 mg and sufentanil 30 μg in 100 ml of normal saline in C-LA group. The epidural labor analgesia solution contained ropivacaine 100 mg, sufentanil 30 μg and esketamine 50 mg in 100 ml of normal saline in E-LA group. The Edinburgh Postnatal Depression Scale (EPDS) was used to screen parturients for depression on admission to the predelivery room and at 2 h and 1, 7 and 42 days after delivery, and EPDS scores were recorded. The patients were diagnosed as having PPD when EPDS score ≥ 9 at 7-42 days after delivery. Peripheral venous blood samples were collected on admission to the predelivery room and at 1 day after delivery to determine the concentrations of serum estrogen, progesterone, 5-hydroxytryptamine and cortisol by enzyme linked inmunosorbent assay. Results:Compared with group C-LA, the EPDS scores were significantly decreased on the 1 and 42 days after delivery( P<0.01), no significant change was found in the incidence of PPD (1.7%/0.8%, P>0.05), no significant change was found in the concentrations of serum estrogen, progesterone, 5-hydroxytryptamine and cortisol on admission to the delivery room ( P>0.05), and the concentrations of serum progesterone and cortisol were significantly increased on 1 day after delivery in group E-LA ( P<0.05). Conclusions:Combination of esketamine is helpful in reducing the risk of postpartum depression when used for epidural labor analgesia, and the mechanism is related to slowing the declines in blood levels of sex hormones and stress hormones after delivery.

Potency of epidural ropivacaine in inhibiting breakthrough pain in primiparae undergoing epidural labor analgesia / 中华麻醉学杂志

Objective:To determine the potency of epidural ropivacaine in inhibiting breakthrough pain in primiparae undergoing labor analgesia with programmed intermittent epidural bolus (PIEB).Methods:American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ primiparae of full-termpregnancy, with a singleton fetus in vertex presentation, aged ≥18 yr, with body mass index < 30 kg/m 2, presenting with breakthrough pain during labor analgesia with PIEB, were enrolled in this study. Ropivacaine 10 ml was epidurally administered, and the concentration was determined by up-and-down sequential allocation. The initial concentration was set at 0.15% in the first patient in each group. Each time the concentration increased/decreased in the next patient depending on whether the patients showed breakthrough pain relief, and the ratio between the two successive doses was 0.9. The criterion of breakthrough pain relief was defined as numerical rating scale score < 4 points within 30 min after epidural injection of ropivacaine. The median effective concentration (EC 50) and 95% confidence interval of ropivacaine in inhibiting breakthrough pain were calculated by Dixon-Massey′s method. Results:Twenty-six patients were finally included in this study.The EC 50 (95% confidence interval)of ropivacaine in inhibiting breakthrough pain was 0.102% (0.088%-0.117%). Conclusions:The EC 50(95% confidence interval) of epidurally administered ropivacaine 10 ml is 0.102%(0.088%-0.117%) when used for inhibiting breakthrough pain during labor analgesia with PIEB in primiparae.

Risk factors for intrapartum fever during labor analgesia and development of a prediction model / 中华麻醉学杂志

Objective:To identify the risk factors for intrapartum fever during labor analgesia and establish the prediction model.Methods:The medical records from pregnant women with intrapartum fever during labor analgesia were retrospectively analyzed. According to whether the highest body temperature ≥38 ℃, the parturients were divided into intrapartum fever group and non-fever group. The general data from patients, duration of hospital stay before labor, induced labor, prenatal hemoglobin concentration, body msaa index (BMI) during pregnancy, artificial rupture of membranes in the incubation period, frequency of vaginal examination and etc. were collected. The risk factors of which P values were less than 0.05 would enter the logistic regression analysis to stratify intrapartum fever-related risk factors, and the weighted score regression prediction model was established. Hosmer-Lemshow Test was used to assess the fit of the model, and the receiver operating characteristic curve was drawn to evaluate the model. The nomogram was drawn for visually presenting the regression model. The clinical calibration curve, decision curve analysis and clinical impact curve were drawn to assess the created prediction model. Results:There were 99 parturients developed fever during labor analgesia, with an incidence of 34.7%. The results of logistic regression analysis showed that duration of hospital stay before labor, prenatal hemoglobin concentrations, BMI during pregnancy, induced labor, artificial rupture of membranes in the incubation period and frequency of vaginal examination were the independent risk factors for intrapartum fever during labor analgesia. The area under the receiver operating characteristic curve was 0.943, 95% confidence interval was 0.916-0.969, the sensitivity was 86.9%, the specificity was 88.6%, and the Youden index was 0.755. The prediction model of the line chart was assessed by Hosmer-Lemshow, P=0.898. Conclusions:Duration of hospital stay before labor, hemoglobin concentrations, BMI during pregnancy, induced labor, artificial rupture of membranes in the incubation period and frequency of vaginal examination are independent risk factors for intrapartum fever during labor analgesia in parturients, and the risk prediction model developed can effectively predict the occurrence of intrapartum fever during labor analgesia.

Factors influencing neonatal outcomes in twin pregnancies undergoing cesarean section: a cross-sectional study

SUMMARY OBJECTIVE: This study aimed to evaluate maternal and fetal characteristics and factors affecting fetal outcomes in twin pregnancies delivered by cesarean section. METHODS: This was a cross-sectional study in a tertiary care referral hospital. The primary outcome was to ascertain the effects of independent factors on the 1st and 5th minute APGAR scores, neonatal intensive care unit admissions, the need for mechanical ventilation, and neonatal mortality. RESULTS: A total of 453 pregnant women and 906 newborns were included in the analysis. The final logistic regression model revealed that early gestational weeks and neonates <3rd weight percentile at the time of delivery were the most significant predictors of all poor outcome parameters in at least one of the twins (p<0.05). General anesthesia for cesarean section was associated with 1st minute APGAR<7 and the need for mechanical ventilation, and emergency surgery was correlated with the need for mechanical ventilation (p<0.05) in at least one of the twins. CONCLUSION: General anesthesia, emergency surgery, early gestational weeks, and birth weight <3rd weight percentile were strongly associated with poor neonatal outcomes in at least one of the twins delivered by cesarean section.

Dual epidural catheters for labor analgesia in a spinal cord injury patient: a case report

Abstract Impediment to local anesthetic solution in the epidural space results in unsatisfactory pain relief during labor epidural. Patients with a history of back trauma and spinal instrumentation have increased rates of epidural failure due to patchy spread of local anesthetic with obliterated epidural space. Dual Epidural Catheters (DEC) can be used in such clinical scenarios with complete labor analgesia and improved patient satisfaction. We present the successful management of a parturient with vertebral fracture at risk for epidural failure and neurologic injury due to bone fragments and inserted cranial and caudal to the fractured vertebra using ultrasound to avoid neurologic sequelae.

Randomized Clinical Trial Comparing Quadratus Lumborum Block and Intrathecal Morphine for Postcesarean Analgesia / Ensaio Clínico Randomizado Comparando Bloqueio do Quadrado Lombar e Morfina Intratecal Para Analgesia Pós-cesariana

Abstract Objective To compare the efficacy of quadratus lumborum (QL) block and intrathecal morphine (M) for postcesarean delivery analgesia. Methods Thirty-one pregnant women with ≥ 37 weeks of gestation submitted to elective cesarean section were included in the study. They were randomly allocated to either the QL group (12.5 mg 0.5% bupivacaine for spinal anesthesia and 0.3 ml/kg 0.2% bupivacaine for QL block) or the M group (12.5 mg bupivacaine 0.5% and 100 mcg of morphine in spinal anesthesia). The visual analog scale of pain, consumption of morphine and tramadol for pain relief in 48 hours, and side effects were recorded. Results Median pain score and/or pain variation were higher in the morphine group than in the QL group (p = 0.02). There was no significant difference in the consumption of morphine or tramadol between groups over time. Side effects such as pruritus, nausea, and vomiting were observed only in the morphine group. Conclusion Quadratus lumborum block and intrathecal morphine are effective for analgesia after cesarean section. Patients undergoing QL block had lower postoperative pain scores without the undesirable side effects of opioids such as nausea, vomiting, and pruritus.

Resumo Objetivo Comparar a eficácia do bloqueio do quadrado lombar (QL) e da morfina intratecal (M) na analgesia pós-cesariana. Métodos Trinta e uma gestantes com ≥ 37 semanas de gestação submetidas a cesariana eletiva foram incluídas no estudo. Eles foram alocados aleatoriamente no grupo QL (12,5 mg de bupivacaína a 0,5% para raquianestesia e 0,3 ml/kg de bupivacaína a 0,2% para bloqueio de QL) ou no grupo M (12,5 mg de bupivacaína a 0,5% e 100 mcg de morfina na raquianestesia). A escala visual analógica de dor, consumo de morfina e tramadol para alívio da dor em 48 horas e efeitos colaterais foram registrados. Resultados A mediana do escore de dor e/ou variação da dor foi maior no grupo morfina do que no grupo QL (p = 0,02). Não houve diferença significativa no consumo de morfina ou tramadol entre os grupos ao longo do tempo. Efeitos colaterais como prurido, náuseas e vômitos foram observados apenas no grupo morfina. Conclusão O bloqueio QL e a morfina intratecal são eficazes para analgesia após cesariana. Os pacientes submetidos ao bloqueio do QL apresentaram menores escores de dor pós-operatória sem os efeitos colaterais indesejáveis dos opioides, como náuseas, vômitos e prurido.

ABSTRACT Introduction: Risk factors associated with complications in the mother-child pair include: history of hypertensive disorders, adolescent pregnancy, drug use, unfavorable obstetric history with a background of miscarriages or abortions, sexually transmitted diseases and urinary tract infections. Objective: To identify the obstetric risk in times of COVID-19 pandemic at the ¨Bastión Popular¨ health area, Guayaquil, Ecuador, from January to June 2021. Method: A descriptive-transversal field research was carried out, with a quantitative approach, which favored the analysis of the obstetric risk categories recorded in the medical history of 117 pregnant women, who signed an informed consent, for the collection of data through home visits, using the obstetric risk scale or score. Results: Outcomes assessment showed, as main result, that the most frequent obstetric risk group was the age group 20 to 24 and the high risk factor was the main category identified. Obstetric risk increased proportionally when the interpregnancy interval was reduce. Conclusions: Young women between 20 and 24 years of age are those who presented the highest obstetric risk, which is correlate with a higher number of gestations, abortions, deliveries and cesarean sections. Therefore, it is necessary to provide women with information about pregnancy and its complications, so that they are able to identify risk factors during pregnancy, delivery and the puerperium.
