RESUMEN
OBJECTIVE: To evaluate whether the concentration of serum lactate during the diagnosis of postpartum hemorrhage (bleeding ≥500 mL during labor or ≥1000 mL during cesarean delivery) predicts severe hemorrhage (SPPH; blood loss ≥1500 mL at end of labor or in the following 24 h). METHODS: A prospective cohort pilot study was conducted of women with a vaginal or cesarean delivery from February 2018 to March 2019 who presented with bleeding ≥500 mL measured by the gravimetric method in a reference hospital in San Luis Potosi, Mexico. Venous blood samples were taken for analysis of serum lactate. A receiver operating characteristic curve determined the serum lactate threshold value for SPPH and χ2 test assessed the difference in serum lactate elevation between SPPH and non-SPPH groups. Lastly, the prognostic capacity between the thresholds was compared. RESULTS: SPPH developed in 43.33% of the 30 women in the study group. The best prognostic threshold was 2.68 mmol/L of serum lactate (odds ratio [OR] 17.88, 95% confidence interval [CI] 2.7-16.8, P < 0.001); sensitivity was 0.85 (95% CI 0.55-0.98); specificity was 0.76 (95% CI 0.50-0.93). CONCLUSION: Serum lactate may be a useful prognostic marker for SPPH, more studies are needed to validate these findings.

Background: The association between coagulation profile and postpartum hemorrhage (PH) is still debated. Objective: To determine the association between hemostatic profile and PH in women with cesarean operation (CO). Methods: We included 92 patients with PH (cases) and 184 without (controls), patients were attended during 2014, at one hospital of the Instituto Mexicano del Seguro Social in Mérida, Yucatán. Demographic, clinical and laboratory data including prothrombin time (PT), activated partial thromboplastin time (aPTT), platelet count (PLC), and fibrinogen concentration were compared among cases and controls using a binary logistic regression model (LRM), from which odd ratios (OR), and 95% confidence intervals (95% CI), were obtained. Results: According to the bivariate comparison, in the LRM categorical data such as parity, any type of hypertensive comorbidity, type of anesthesia, and categorized aPTT (< 38 vs. ≥ 38 seconds), and one continuous variable (gestational age) were included. Having some hypertensive comorbidity (OR 3.55, 95% CI: 1.95-6.47), type of anesthesia (regional anesthesia, OR 0.27, 95% CI: 0.13-0.55) and aPTT (< 38 seconds, OR 0.26, 95% CI: 0.10-0.66) were all statistically significant. Categorized PT, platelet count and fibrinogen concentration, were not statistically significant. Conclusions: In this sample, having some hypertensive comorbidity increased risk of PH more than three times, while regional anesthesia and aPTT < 38 seconds reduced risk in 73% and 74%, respectively. Neither platelet count, nor fibrinogen concentration, or the PT categories modified risk of PH.
Introducción: la asociación entre el perfil hemostático y la hemorragia obstétrica posparto (HO) es controversial. Objetivo: determinar la asociación entre el perfil hemostático y la HO en pacientes con operación cesárea (OC). Métodos: se incluyeron 92 pacientes con HO (casos) y 184 sin HO (controles), atendidas durante 2014 en un hospital del Instituto Mexicano del Seguro Social de Mérida, Yucatán. Diversas variables, incluyendo la cuenta plaquetaria, el tiempo de protrombina (TP), el tiempo de tromboplastina parcial activado (TTPa) y el fibrinógeno plasmático, fueron comparadas entre casos y controles, mediante un modelo de regresión logística del que se obtuvieron razones de momios (RM) e intervalos de confianza de 95% (IC 95%). Resultados: con base en el análisis univariado se incluyeron en el modelo la paridad, comorbilidad hipertensiva (hipertensión crónica, preeclampsia, eclampsia), tipo de anestesia y el TTPa categorizado (< 38 frente a ≥ 38 segundos) y la edad gestacional (como dato continuo), resultando significativamente diferentes la presencia de comorbilidad hipertensiva (RM 3.55, IC 95%: 1.95-6.47), el tipo de anestesia (regional, RM 0.27, IC 95%: 0.13-0.55) y el TTPa (< 38 segundos, RM 0.26, IC 95%: 0.10-0.66). Conclusiones: en esta muestra, tener comorbilidad hipertensiva incrementó más de tres veces el riesgo de HO, la anestesia regional lo redujo en 73% y el TTPa < 38 segundos lo redujo en 74%. Ni el TP, ni la cuenta plaquetaria modificaron el riesgo.

Obstetric hemorrhage is the leading cause of maternal mortality, responsible of 143,000 deaths every year. Thromboelastography is a tool that allows measuring the viscoelastic, dynamic and global properties of the blood, offering valuable information of coagulation alterations and help to guide early goal directed transfusional therapy. The purpose of this review is to evaluate the evidence of this tool in obstetric hemorrhage and the management of the associated coagulopathy.

OBJECTIVE: To investigate the association between hypertensive disorders and postpartum hemorrhage (PPH), by measuring the hemoglobin (Hb) and hematocrits (Ht) levels among women attending a university hospital in the Sao Paulo countryside. METHOD: Epidemiological, cross-sectional study, conducted with 100 primiparous, in the period between August and December 2012. Hemoglobin and hematocrit dosages were tested upon admission of the mother and 48 hours after delivery. Values ≥ 10% drop in the hematocrit numbers when compared to those shown in admission, were considered as HPP. HPP was considered the dependent variable and the independent variables were socioeconomic, pathological, prenatal care, admission, delivery and assistance. Univariate and bivariate statistics were used, with 5% significance level. RESULTS: The hypertensive disorders were the most commonly occurring disorders; there was the presence of positive correlation between the fall in Ht and Hb levels and there was no association found between hypertensive disorders and HPP. CONCLUSIONS: Primiparous not suffering from hypertensive disorders were more likely to present PPH.

Objetivo: Describir el uso del balón SOS Bakri en el tratamiento de la hemorragia posparto vaginal por atonía uterina después de la falla del tratamiento médico. Métodos: Se presenta una serie de 15 pacientes con hemorragia posparto vaginal por atonía uterina, tratadas satisfactoriamente con taponamiento uterino con balón SOS Bakri luego de no responder a tratamiento médico ni a masaje uterino. Resultados: La edad promedio de las pacientes fue 22,7 (± 6,8) años. La edad gestacional promedio fue 36,3 (± 2,6) semanas. El balón se insertó en los primeros 30 minutos del diagnóstico de la atonía uterina. El tiempo total que permaneció el balón en útero fue de 13,6 (± 6,1) horas. La pérdida hemática posterior a la colocación del balón fue en total 265,3 (± 258,1) cm3. El balón SOS Bakri fue efectivo en 100 % de las pacientes. Ninguna de las pacientes ameritó histerectomía. Conclusiones: El balón SOS Bakri es una alternativa eficaz mínimamente invasiva, económica y de fácil acceso en la terapéutica de la AU que no responde al tratamiento médico.
Objective: To describe the use of SOS Bakri Balloon in the treatment of postpartum hemorrhage after unsuccessful medical treatment of uterine atony. Method: We describe a case series of 15 patients with severe uterine atony after vaginal delivery that were successfully managed with SOS Bakri balloon after failed uterine massage and medical treatment. Results: The mean patient age was 22.7 (± 6.8) years. The mean gestational age was 36.3 (± 2.6) weeks. The balloon was inserted within 30 minutes of diagnosis of uterine atony. The mean length of balloon placement was 13.6 (± 6.1) hours. The mean total blood loss post balloon insertion was of 265.3 (± 258.1) cm3. The SOS Bakri balloon was effective 100 % of the time. None of the patient required hysterectomy. Conclusion: Insertion of SOS Bakri balloon is a simple conservative live saving alternative in the management of postpartum uterine atony.

OBJECTIVE: To describe the clinical and hormonal characteristics of patients with Sheehan syndrome. METHODS: We performed a 20-year cohort study (1969 to 1989) of patients with Sheehan syndrome who were cared for in the endocrinology unit of the México Hospital in San José, Costa Rica. Medical history, physical examination findings, and laboratory test results were documented and reviewed. RESULTS: Sixty patients with a diagnosis of Sheehan syndrome were identified. Mean age at diagnosis was 45.8 ± 10.6 years. The average time between the previous obstetric event and Sheehan syndrome diagnosis was 13 years. Thirteen patients (22%) had a home birth. The median parity was 7. The most frequent obstetric antecedents were history of obstetric hemorrhage in 49 (82%), shock in 28 (47%), blood transfusion in 26 (43%), and peripartum hysterectomy in 4 (7%). The most common symptoms included asthenia and adynamia in 51 (85%), amenorrhea in 44 (73%), loss of axillary or pubic hair in 40 (67%), and agalactia in 40 (67%). The most common findings on physical examination were absence of axillary hair in 56 (93%) and pubic hair in 56 (93%), dry skin in 49 (82%), and pallor in 42 (70%). When a combined pituitary test was performed, 38 of 38 patients (100%) had human growth hormone deficiency, 29 of 30 patients (97%) had adrenal insufficiency, 8 of 10 patients (80%) had hypothyroidism, 8 of 12 patients (67%) had hypogonadism, and 9 of 13 patients (69%) had prolactin deficiency. Despite early onset of symptoms, Sheehan syndrome was diagnosed relatively late in these 60 patients. Hemorrhage during the last delivery, especially if severe and/or associated with shock or transfusion, was the most important obstetric antecedent event. Absence of amenorrhea or presence of postpartum lactation did not exclude the diagnosis. Abnormal responses of human growth hormone to insulin tolerance testing and of prolactin to thyrotropin-releasing hormone confirm the diagnosis. CONCLUSIONS: Identification of patients affected with Sheehan syndrome is critical to avoid delays in diagnosis and treatment. Appropriate replacement therapy is capable of yielding complete remission of symptoms.

OBJECTIVE: To study maternal complication associated to delivery and the puerperium period in pregnancies affected by von Willebrand's disease. METHODS: Chart data of all the pregnant women with diagnosis of von Willebrand disease were retrospectively reviewed. All cases with von Willebrand's disease that had given birth at this institution, between March 2001 and August 2007, were analyzed. The following variables were investigated: mode of delivery, hemorrhage complications during delivery and postpartum, maternal blood exams and perinatal results. Variables were studied descriptively, using absolute and relative frequencies, means, medians and standard deviations. RESULTS: 13 pregnancies of eight women with the disease were reviewed. During this sane period, there were 13,037 deliveries in the institution, resulting in an incidence of 0.1%. Six women (75%) were type 1 disease and, two (25%) were type 2. The last Factor VIIIc activity presented a mean value of 98.5%. A Cesarean section was performed in nine pregnancies, with epidural anesthesia in seven. Delivery complication occurred in two cases: one presented placental abruption and a Cesarean was performed. The other, presented postpartum hemorrhage in the first day and required reposition with factor VIII. Two cases received factor VIII before Cesarean section. Fetal growth restriction was detected in five pregnancies (38.5%). Mean birth weight was of 2676 grams and one case presented 1st minute Apgar score below seven. CONCLUSION: Delivery in patients with von Willebrand disease has a favorable evolution when specific assistance is provided. In these pregnancies,fetal growth should be monitored.

OBJETIVO: Analisar as complicações maternas associadas ao parto e puerpério, bem como os resultados perinatais, em gestantes portadoras da doença de von Willebrand. MÉTODOS: Foram analisados os prontuários de todas as gestantes com diagnóstico de doença de von Willebrand, cujo parto foi realizado nesta instituição no período compreendido entre março de 2001 e agosto de 2007. Foram investigadas características relativas à via de parto, incidência de complicações hemorrágicas no parto e no puerpério imediato, perfil dos exames laboratoriais maternos e resultados perinatais. As variáveis foram estudadas descritivamente, calculando-se freqüências absolutas e relativas, médias, medianas e desvios padrão. RESULTADOS: Foram revisadas 13 gestações em oito pacientes portadoras da doença. No período ocorreram 13.037 partos na instituição, perfazendo incidência de 0,1 por cento. Seis pacientes (75 por cento) apresentavam o tipo 1 da doença, e duas (25 por cento) o tipo 2. No terceiro trimestre, a média da atividade do fator VIIIc foi de 98,5 por cento. A cesárea foi realizada em nove casos (69 por cento), cuja anestesia foi do tipo raquidiana em sete casos. Como complicação do parto, um caso evoluiu com descolamento prematuro da placenta e foi realizada a cesárea. Um caso apresentou sangramento no primeiro pós-parto, necessitando reposição do fator VIII. Em dois casos foi realizada a reposição profilática do fator VIII antes da cesárea. A restrição do crescimento fetal ocorreu em cinco casos (38,5 por cento). O peso dos RNs apresentou média de 2676 gramas e um caso (7,8 por cento) apresentou Apgar de 1º minuto inferior a sete. CONCLUSÃO: O parto em gestantes com diagnóstico de doença de von Willebrand tem evolução favorável quando cuidados são tomados procurando oferecer assistência específica. O crescimento fetal deve ser monitorizado nessas gestantes.
