Introduction: Obstetric hemorrhage is considered a major cause of maternal mortality. Recognition of women at risk of developing complications during obstetric hemorrhage is the first action to promote optimized treatment and avoid death. Objective: Identify risk factors for complications in patients with obstetric hemorrhage. Methods: Observational, analytical case-control study, with 12 cases (with complications) and 24 controls (without complications). The summary measures were applied for each type of variables and the determination of the risk factors by applying the odds ratio (OR), the SPSS statistical package version 26.0 was used, with a confidence interval (CI) of 95 percent. Results: The combination of hypovolemic shock, plus acute renal failure, was the most frequent complication for 13.8 percent. Uterine atony predominated for 50.0 percent as the cause of hemorrhage. The predictive variables of complications were: creatinine value ≥ 113 µmol/L (OR= 19.08; CI: 2.75-138.36), international normalized ratio ≥ 2 (OR= 4.66; CI: 1. 46-14.90), hematocrit < 0.23 (OR= 4.00; CI: 1.76-9.08) and hemoglobin < 70 g/L (OR= 2.22; CI: 1.25-3.95). Conclusions: Creatinine ≥ 113 µmol/L, international normalized ratio ≥ 2, hematocrit < 0.23 and hemoglobin < 70 g/L are the main risk factors identified for the development of complications during obstetric hemorrhage(AU)

OBJECTIVE: The main aim of this study was to assess the associated factors for selective mediolateral episiotomy at a tertiary, academic hospital. METHODS: A retrospective cohort analysis between 2017 and 2019 was performed. The primary outcome was the prevalence of selective mediolateral episiotomy. Independent variables were maternal, intrapartum, and neonatal characteristics. A significance level of 5% was established, and univariate and multivariate analyses with logistic regression models were performed. RESULTS: From 2,761 vaginal deliveries eligible for inclusion during this period, the prevalence of selective mediolateral episiotomy was 18.7%. Univariate analysis has shown that non-white women were protective factors (OR=0.77 [0.63-0.96]; p=0.02) for episiotomy; primiparity (OR=2.61 [2.12-3.21]; p<0.01), number of vaginal examinations between 6-10 repetitions (OR=3.16 [2.48-4.01]; p<0.01) and 11-20 repetitions (OR=5.40 [3.69-7.90]; p<0.01), longer second stage duration (OR=1.01 [1.00-1.02]; p<0.01), and women with gestational age more than 37 weeks were risk factors. Multivariate analysis reported that second stage duration (AOR=1.01 [1.00-1.03]; p<0.01), primiparity (AOR=2.03 [1.34-3.06]; p<0.01), and number of vaginal examinations between 6-10 repetitions (AOR=2.36 [1.50-3.70]; p<0.01) and 11-20 repetitions (AOR=3.29 [1.74-6.20]; p<0.01) were remained as risk factors for selective mediolateral episiotomy. CONCLUSION: A higher number of vaginal examinations during labor (over six repetitions), longer duration of second stage labor, and primiparity were risk factors associated with selective mediolateral episiotomy.

AIM: Vaginal delivery is a well-known risk factor for pelvic floor muscle (PFM) injuries, mainly when associated to prolonged labor, instrumental birth and perineal trauma such as episiotomy and perineal tears. The purpose of this meta-analysis was to test the hypothesis that episiotomy and severe perineal tear may increase the risk of pelvic floor damage. METHODS: We performed a systematic literature search through electronic databases including MEDLINE via PubMed, LILACS via BVS, Embase via Elsevier and Cochrane Library up to January 2019. We included articles that reported as outcome one or more morphological aspects of the PFM evaluated by ultrasonography in primiparous women three to 24 months postpartum. This review is registered in the PROSPERO database (registration number: CRD42017075750). RESULTS: the final selection was composed of 18 articles for the systematic review, and 10 for the meta-analysis. Women with levator ani muscle (LAM) avulsion were 1.77 times more likely to have undergone episiotomy (OR = 1.77, CI 95% 1.25-2.51, five trials), 4.31 times more likely to have severe perineal tear (OR = 4.31, CI 95% 2.34-7.91, two trials). Women with defects in the anal sphincters were 2.82 times more likely to have suffered severe perineal tear (OR = 2.82, 95% CI 1.71-4.67, three trials). CONCLUSIONS: Both episiotomy and severe perineal tear are risk factors for LAM avulsion and anal sphincter injury, and this can be useful for identifying women who are at greater risk of developing PFM dysfunctions.

OBJECTIVES: We aimed to establish new cut-off values for SIRS (Systemic Inflammatory Response Syndrome) variables in the obstetric population. METHODS: A prospective cohort study in pregnant and postpartum women admitted with systemic infections between December 2017 and January 2019. Patients were divided into three cohorts: Group A, patients with infection but without severe maternal outcomes (SMO); Group B, patients with infection and SMO or admission to the intensive care unit (ICU); and Group C, a control group. Outcome measures were ICU admission and SMO. The relationship between SIRS criteria and SMO was expressed as the area under the receiver operating characteristics curve (AUROC), selecting the best cut-off for each SIRS criterion. RESULTS: A total of 541 obstetric patients were enrolled, including 341 with infections and 200 enrolled as the reference group (Group C). The patients with infections included 313 (91.7%) in Group A and 28 (8.2%) in Group B. There were significant differences for all SIRS variables in Group B, compared with Groups A and C, but there were no significant differences between Groups A and C. The best cut-off values were the following: temperature 38.2 °C, OR 4.1 (1.8-9.0); heart rate 120 bpm, OR 2.9 (1.2-7.4); respiratory rate 22 bpm, OR 4.1 (1.6-10.1); and leukocyte count 16,100 per mcl, OR 3.5 (1.6-7.6). CONCLUSIONS: The cut-off values for SIRS variables did not differ between healthy and infected obstetric patients. However, a higher cut-off may help predict the population with a higher risk of severe maternal outcomes.

OBJECTIVE: This study aimed to investigate the prevalence of severe perineal trauma (obstetric and anal sphincter injury [OASIS]) in a tertiary high-risk pregnancy facility and the associated factors. METHODS: A retrospective electronic chart review on perineal lacerations was performed from the period of April 2017 to February 2019. Obstetric and anal sphincter injury was diagnosed by a rectal examination. Primary outcome was the prevalence of OASIS (third- and fourth-degree perineal tear). Independent variables were maternal, intrapartum, and neonatal characteristics. Univariate and multivariate analyses with logistic regression models were performed. A P value lower than 0.05 was considered significant. RESULTS: The prevalence of OASIS (third/fourth-degree laceration) was 1.51% (43/2846) in our population. Our population was mostly white (66.3%) and mostly primiparous (52.1%). By comparison, the prevalence of first/second-degree laceration was 43% (1223/2846). Selective episiotomy occurred in 18.73% (517/2761) of patients, and it was not associated with OASIS (P = 0.211). Advanced maternal age (P = 0.196), higher number of vaginal examinations (P = 0.169), fetal presentation (P = 0.533), and duration of second stage (P = 0.757) were not associated with OASIS. Univariate analysis has found that forceps delivery (odds ratio [OR], 3.68 [1.74-7.79]; P = 0.001), neonatal macrossomy (OR, 3.42 [1.02-11.43]; P = 0.045), and larger head circumference (OR, 1.15 [1.02-1.32]; P = 0.026) were risk factors for OASIS, whereas higher gravidity reduced the risk (OR, 0.61 [0.42-0.91] for OASIS. However, after multivariate analysis, only head circumference (OR, 1.86 [1.10-3.14]; P = 0.020) remained as a risk factor. CONCLUSIONS: Larger neonatal head circumference increased in 86% the risk for severe perineal trauma in this cohort of women.

INTRODUCTION AND HYPOTHESIS: We hypothesized whether a non-episiotomy protocol or administration of selective episiotomy as an intrapartum intervention would modify the incidence of obstetric anal sphincter injuries (OASIS). METHODS: We registered this systematic review with the PROSPERO database (CRD42018111018). Prospective randomized controlled trials (RCTs) were included from databases until February 2019. The primary outcome was OASIS, and the secondary outcomes were any perineal trauma, duration of the second stage of labor, instrumental delivery, and post-partum hemorrhage. The risk of bias (Cochrane Handbook) and the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) criteria were used to assess the RCTs. RESULTS: A total of 1,833 results (PubMed 650, SCOPUS 1,144, Cochrane Library 33, LILACS 6) were obtained. However, only 2 studies fulfilled the criteria for quantitative analysis and meta-analysis (n = 574). The non-episiotomy arm included two episiotomies (1.7% of deliveries), whereas the selective episiotomy included 33 episiotomies (21.4%). Performance of selective episiotomy demonstrated no difference compared with that of the non-episiotomy group with regard to OASIS (OR = 0.46 [0.15-1.39]; n = 543; I2 = 0%,p = 0.17), any perineal trauma (OR = 0.90 [0.61-1.33]; I2 = 0%, n = 546, p = 0.59), instrumental delivery (OR = 1.40 [0.80-2.45]; I2 = 0%, n = 545, p = 0.24), duration of the second stage of labor (MD = -3.71 [-21.56, 14.14]; I2 = 72%,n = 546, p = 0.68), perineal pain (MD = 0.59 [0.01-1.17]; I2 = 0%,p = 0.05), and post-partum hemorrhage (OR = 1.75 [0.87-3.54]; I2 = 0%,n = 546,p = 0.12). The evaluated studies displayed a low risk of bias in at least four of the seven categories analyzed. GRADE demonstrated a low certainty for severe perineal tears, postpartum hemorrhage, duration of the second stage of labor, and a moderate certainty for any perineal tear. CONCLUSIONS: There was no significant difference between non-episiotomy and selective episiotomy regarding OASIS. No RCT was able to confirm a benefit of the non-performance of episiotomies in the non-episiotomy arm.

AIM: There is much discussion about the advantages and disadvantages of a trial of labor after cesarean (TOLAC). Some data suggest the greater the likelihood of success, the lower the risks of TOLAC. Our goal was to identify clinical and demographic variables associated with a failed TOLAC, available at admission for spontaneous labor and until 3 h later, with the aim of building two scores for risk of failed TOLAC. METHODS: This is a nested case-control study with live births to women with one previous cesarean, in a public Brazilian teaching hospital. Preterm, induction, noncephalic presentations, twins, fetal malformations were excluded. Cases were failed TOLAC, and controls, the successful TOLAC. It was accessed the association of the cases with 20 variables (P < 0.05). Associated variables were tested in multivariate analysis to build the scores, which were internally validated. RESULTS: We included 260 TOLAC, 42 cases and 218 controls. We found 11 variables associated with failed TOLAC. In the score to be applied at admission, we included hypertension, fundal height, previous vaginal birth and dilatation at admission. In the second score hypertension, fundal height at admission, membrane status and difference in dilatation 3 h after admission. Both scores presented good performance in the receiver-operator curve (areas under curve: 0.73 and 0.84, respectively). Both scores were translated into nomograms for clinical use. CONCLUSION: Two scores were built for risk of failed TOLAC, to be applied at admission and 3 h later. We believe that choosing the more favorable cases makes risks of TOLAC lower.

La hemorragia postparto es una de las complicaciones obstétricas más temidas por los obstetras a nivel mundial, pudiendo causar la muerte de las puérperas. El objetivo de este estudio fue determinar las causas de las hemorragias y las patologías asociadas a estas en las pacientes atendidas en el Hospital Gineco-Obstétrico Enrique C. Sotomayor de Guayaquil, Ecuador en el periodo 20162018 y que estaban en su puerperio inmediato. Las mujeres atendidas en ese periodo en dicha institución fueron 528, de las cuales 160 presentaron hemorragias en el puerperio inmediato. Las hemorragias por desgarro del suelo pélvico representaron un 48,75% y se asociaron en un 35% a hematomas en las paredes del suelo, las causadas por retención de restos placentarios, constituyeron un 26,25% y el 20% presentó acretismo placentario y finalmente las ocasionadas por atonía uterina fueron de un 25%, correspondiendo un 25% a coagulopatías. Se concluyó que las hemorragias postparto por desgarro del suelo pélvico son la causa con mayor porcentaje en contraposición con otros estudios que indican que la atonía uterina es la causa más frecuente de hemorragias postparto inmediato(AU)
Postpartum hemorrhage is one of the obstetric complications most feared by obstetricians worldwide, and may cause the death of puerperal women. The objective of this study was to determine the causes of hemorrhages and the pathologies associated with these in the patients treated at the Enrique C. Sotomayor Obstetric Hospital of Guayaquil, Ecuador in the period 2016 - 2018 and that were in their immediate puerperium. The women who attended in that period were 528 women, 160 of them presented hemorrhages in the immediate puerperium. Hemorrhages by pelvic floor tearing represented 48.75% and 35% were associated to bruises in the floor walls, those caused by retention of placental remains constituted 26.25% and 20% presented accretism and finally those caused by uterine atony were 25% while 25% corresponded to coagulopathies. We concluded that the postpartum hemorrhages by tearing of the pelvic floor are the cause with the highest percentage; in contrast to other studies, which indicate that uterine aton is the most frequent cause of immediate postpartum hemorrhage(AU)

AIM: To compare the effect on epidural catheter migration of three different types of dressing used in labor. INTRODUCTION: Failure of labor epidural is due to multiple factors including catheter migration. Epidural catheter migration has been showed to be related to body mass index and patient position. The dressing technique also influences catheter migration and the risk of epidural failure. METHODS: Patients were randomly allocated to one of three groups based on type of dressing of labor epidural: TegadermTM (Group T), TegadermTM with sticky pad (Group P), and TegadermTM with Steri-StripTM (Group S). Measured variables included parity, gestational age, body mass index (BMI), level of puncture and distance of epidural catheter migration. RESULTS: There was an overall difference in epidural catheter migration (ECM) distance among different groups (p<0.05). Pairwise comparison revealed only a significant difference between groups P and T (0.76±1.35 vs. -0.14±1.03, p<0.01). CONCLUSION: Taping the lumbar epidural catheter used for labor analgesia with TegadermTM is inferior to TegadermTM with sticky pad or with Steri-StripTM in terms of catheter migration. There is no association of catheter migration and BMI.
Objetivo: Comparar el efecto de tres diferentes tipos de fijación sobre la migración del catéter epidural durante el trabajo de parto. Introducción: El fallo del bloqueo epidural en el trabajo de parto se debe a múltiples factores incluyendo la migración de catéter. La migración de catéter epidural se ha relacionado con el índice de masa corporal y la posición, así como con movimientos del paciente. La técnica de fijación también afecta la migración de catéter y el riesgo de bloqueo epidural fallido. Método: Las pacientes fueron aleatorizadas y asignadas a uno de tres grupos según el tipo de fijación: TegadermTM (Grupo T), TegadermTM con almohadilla adhesiva (Grupo P) y Tegaderm TM con Steri-StripTM (Grupo S). Las variables evaluadas incluyeron paridad, edad gestacional, índice de masa corporal (IMC), nivel de punción y distancia de migración del catéter epidural. Resultados: Se detectó una diferencia en la distancia de migración de catéter epidural entre los diferentes grupos (p<0.05). La comparación reveló diferencia únicamente entre los grupos P y T (0.76±1.35 vs. -0.14±1.03, p<0.01). Conclusión: TegadermTM como método de fijación de catéter epidural en el trabajo de parto resultó ser inferior al TegadermTM con almohadilla adhesiva o con Steri-StripTM en términos de migración de catéter. No existe una asociación entre migración de catéter epidural e IMC.

Objective: To review the concepts underlying breech presentation delivery as well as the semiology and the obstetric maneuvers contributing to a successful perinatal maternal outcome. Materials and methods: Based on a hypothetical scenario to set the stage for a practical approach to the topic, an explanatory paper built on a narrative review is created in order to examine the principles related to diagnosis, mechanism of delivery and maternal care, emphasizing maneuvers to ease fetal extraction. Results: Breech presentation delivery must be managed through the vaginal canal when already in the expulsion phase with fetal engagement. For diagnosis and care, it is essential to know the unique semiology and physiology of this condition as well as the obstetric maneuvers to facilitate an uncomplicated delivery. Results: The mechanism of childbirth in breech presentation is complex and requires knowledge of its physiology and multiple obstetric maneuvers on the part of the obstetrician as well as the general practitioner, in order to ensure adequate care when there is no other option.
TITULO: ATENCIÓN DEL PARTO CON FETO EN PRESENTACIÓN PELVIANA: REVISIÓN DE LA SEMIOLOGÍA, EL MECANISMO Y LA ATENCIÓN DEL PARTO. Objetivo: Revisar los conceptos que subyacen al trabajo de parto con feto en presentación pelviana, su semiología y las maniobras obstétricas que facilitan un resultado materno perinatal exitoso. Materiales y métodos: A partir de un caso hipotético que ambienta de manera práctica el tema, se crea un documento explicativo construido a partir de una revisión narrativa, en donde se examinan los preceptos relacionados con el diagnóstico, el mecanismo del parto en presentación pelviana y el manejo intraparto de la gestante, con énfasis en la adecuada ejecución de las maniobras que facilitan la extracción fetal. Resultados: El parto en presentación pelviana debe ser atendido por vía vaginal cuando se encuentra en periodo expulsivo con encajamiento cumplido. Para su diagnóstico y atención es esencial hacer una adecuada identificación de la presentación, así como conocer su fisiología, la indicación y adecuada ejecución de las maniobras obstétricas que facilitan un parto sin complicaciones. Resultados: El mecanismo del parto en presentación pelviana es complejo y requiere, cuando no hay otra alternativa para la atención, que tanto el obstetra como el médico general conozcan su fisiología y las múltiples maniobras obstétricas que facilitan obtener buen resultado materno perinatal.
