Estado actual de la cefalea postpunción meníngea en un hospital colombiano / Status of post-dural puncture headache in a Colombian hospital

Introducción: La cefalea postpunción meníngea (CPPM) posterior a la anestesia raquídea es una de las complicaciones más frecuentes asociadas a factores intrínsecos del paciente y de la técnica anestésica. Objetivo: Describir la frecuencia y los factores asociados con el desarrollo de la cefalea postpunción meníngea. Materiales y métodos: Serie retrospectiva de pacientes que ingresaron a un hospital de segundo nivel y se les confirmó el diagnóstico de cefalea secundaria a la anestesia raquídea. Resultados: Serie de 49 casos, 88 % de sexo femenino y 12 % de sexo masculino, con una edad media de 27,7 años. Los procedimientos quirúrgicos con desenlace de CPPM fueron: cirugías de ginecología y obstetricia (63 %), cirugías de urgencias de otras especialidades (28 %) y cirugías electivas (8 %). La técnica anestésica se realizó con agujas biseladas tipo Quincke calibre 25 gauge (G) en 14%, calibre 26 G 33 % y 27 G 53 %. El 51 % se realizó en posición de sedestación y el 49 % en decúbito lateral izquierdo. El 10% de los casos se manejó con parche hemático, en tanto que el antecedente de migraña se presentó en el 8 %. Discusión: En la actualidad, el uso de agujas con diseño de punta cónica es el estándar de oro, ya que permite obtener resultados confiables y disminuye complicaciones como la CPPM. Conclusión: La CPPM luego de una anestesia espinal se relacionó con factores como la edad (joven), el sexo (femenino) y el uso de agujas biseladas. Los otros factores de riesgo identificados fueron poco concluyentes, aunque no se pueden descartar, debido a la naturaleza de este estudio.

Introduction: Post dural puncture headache (PDPH) following spinal anesthesia is one of the most frequent complications associated with intrinsic patient and anesthetic technique factors. Objective: To describe the frequency and associated factors related to the development of PDPH. Materials and methods: Retrospective series of patients admitted to a second level hospital with a confirmed diagnosis of headache secondary to spinal anesthesia. Results: Series of 49 cases, 88 % female and 12 % male, mean age 27.7 years. The surgical procedures resulting in CPPM were gynecology and obstetrics surgeries 63 %, emergency surgeries of other specialties 28 % and elective surgeries 8 %. The anesthetic technique was performed with beveled needles Quincke type 25 gauge (G) in 14 %, 26 G gauge 33% and 27 G 53 %. In the seated position 51 % and in the left lateral decubitus position 49% were performed. A blood patch was used in 10 % of the cases and a history of migraine was present in 8 %. Discussion: The use of needles with conical tip design is currently the gold standard, they give reliable results and reduce complications such as PDPH. Conclusion: PDPH after spinal anesthesia was related to factors such as age (young), sex (female) and the use of traumatic needles. The other risk factors identified were inconclusive, although they cannot be ruled out due to the nature of this study.

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.

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.

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.

Catéter epidural seccionado: reporte de un caso y revisión de literatura / Sectioned epidural catheter: a case report and review of literature / Ruptura de cateter epidural: relato de caso e revisão da literatura

Resumen: La ruptura y retención de un fragmento de catéter peridural es una complicación poco frecuente de la analgesia epidural. Si bien generalmente requiere una conducta expectante con evolución sin mayores complicaciones, su importancia está dada por la escasa evidencia en cuanto al manejo, teniendo en cuenta que puede derivar en una intervención neuroquirúrgica, con sus riesgos y complicaciones. Exponemos el caso de una paciente que tuvo como complicación la ruptura y retención de un fragmento de catéter peridural durante la colocación del mismo para analgesia del parto.

Summary: Rupture and retention of an epidural catheter fragment is a rare complication of epidural analgesia. Although it generally requires expectant management and evolves without major complications, the event is important given the lack of evidence regarding treatment and considering it can lead to a neurosurgical intervention, what involves risks and complications. The study describes the case of a patient whose complication was the rupture and retention of a fragment of an epidural catheter during labor analgesia.

Resumo: A ruptura e retenção de um fragmento de cateter epidural é uma complicação rara da analgesia epidural. Embora geralmente exija uma gestão expectante com evolução sem grandes complicações, a importância é dada pela escassa evidência relativa ao manejo, considerando que pode levar à uma intervenção neurocirúrgica, com os correspondentes riscos e complicações.

Differentiation of affected and nonaffected ovaries in ovarian torsion with magnetic resonance imaging texture analysis

SUMMARY OBJECTIVE: This study aimed to evaluate the feasibility of texture analysis on T2-weighted axial images in differentiating affected and nonaffected ovaries in ovarian torsion. METHODS: We included 22 torsioned ovaries and 19 healthy ovaries. All patients were surgically proven ovarian torsion cases. On T2-weighted axial images, ovarian borders were delineated by the consensus of two radiologists for magnetic resonance imaging-based texture analysis. Statistical differences between texture features of affected and nonaffected ovaries were assessed. RESULTS: A total of 44 texture features were extracted from each ovary using LIFEx software. Of these, 17 features were significantly different between affected and nonaffected ovaries in ovarian torsion. NGLDM_Coarseness and NGLDM_Contrast, which are the neighborhood gray-level difference matrix parameters, had the largest area under the curve: 0.923. The best cutoff values for the NGLDM_Contrast and NGLDM_Coarseness were 0.45 and 0.01, respectively. With these cutoff levels, NGLDM_Contrast had the best accuracy (85.37%). CONCLUSION: Magnetic resonance imaging-based texture analysis on axial T2-weighted images may help differentiate affected and nonaffected ovaries in ovarian torsion.

Prácticas y experiencias de violencia obstétrica y gineco-obstétrica como violencia de género en Chile

Objetivo Describir la experiencia de mujeres que han sufrido violencia obstétrica y gineco-obstétrica en Chile. Métodos Estudio cualitativo en el que participaron 34 mujeres entre 18 y 60 años que experimentaron algún tipo de violencia (obstétrica o gineco-obstétrica) en Chile. Se emplearon entrevistas en profundidad. El análisis se realizó siguiendo los procedimientos del análisis temático. Resultados La violencia obstétrica es un proceso que marca las relaciones de poder médico en distintos niveles: desde lo procedimental hasta el trato que se tiene con las propias mujeres. Esto puede provocar en ellas diversos estados emocionales y psicológicos catalogados como negativos y traumáticos. Discusión La violencia obstétrica y gineco-obstétrica es una dimensión de la violencia de género, pues representa cómo la mujer ha sido instrumentalizada en los procedimientos y atenciones médicas. Se evidencia la necesidad de profundizar en las relaciones de poder médico y en las prácticas gineco-obstétricas para la generación de políticas que protejan los derechos reproductivos y sexuales de las mujeres.

Objective To describe the experience of women who have suffered obstetric and gynecological violence in Chile. Methods Using a qualitative methodology, this study involved the participation of 34 women aged between 18 and 60 years who have experienced some form of violence (obstetric or gynecological violence) in Chile. In-depth interviews were conducted, and subsequently, the analysis was carried out following the procedures of thematic analysis. Results Obstetric violence is a process that marks medical power relations at different levels, from the procedural to the treatment of the women themselves, provoking diverse emotional and psychological states that are associated as negative and traumatic. Discussion Obstetric and gynecological violence is a dimension of gender-based violence as far as it represents how women have been instrumentalized in medical procedures and care. It is evident that there is a need to go deeper into medical power relations and gynecological-obstetric practices in order to generate policies that protect women's reproductive and sexual rights.

Altura uterina versus ecografía obstétrica para detectar macrosomía fetal. Hospital San Juan de Kimbiri, Perú

RESUMEN Fundamento Aunque la ecografía obstétrica es ampliamente utilizada en los niveles primario y secundario de salud para la detección de macrosomía fetal, la altura uterina también puede resultar útil, sobre todo, en contextos sanitarios desprovistos de equipamiento tecnológico. Objetivo determinar la correlación entre altura uterina versus ecografía obstétrica y el diagnóstico de macrosomía fetal. Métodos estudio descriptivo, correlacional, en madres no diabéticas de partos a término con neonatos macrosómicos, realizado en un hospital público del Valle de los ríos Apurímac, Ene y Mantaro, Perú. Las variables del estudio: edad materna, índice de masa corporal pregestacional, número de embarazos, edad gestacional al parto, y vía del parto. Se emplearon los coeficientes de correlación Rho de Spearman, y Pearson, ambos con intervalos de confianza al 95 % y error del 5 %. Resultados la estimación del peso fetal y la macrosomía se correlacionaron con la altura uterina (R Pearson 0,05). Entre las características maternas asociadas a neonatos macrosómicos, se hallaron la obesidad pregestacional (Rho = 0,009) y la condición de multigesta (Rho = 0,04). La estimación del peso fetal mayor a 4000 g tuvo mayor porcentaje de acierto (26,3 %) por ecografía obstétrica. Conclusión la ecografía obstétrica mostró mayor correlación que la altura uterina con el diagnóstico de macrosomía fetal.

ABSTRACT Background Although obstetric ultrasound is widely used at primary and secondary health levels for the detection of fetal macrosomia, uterine height can also be useful, especially in health contexts lacking technological equipment. Objective to determine the correlation between uterine height versus obstetric ultrasound and the diagnosis of fetal macrosomia. Methods descriptive, correlational study in non-diabetic mothers of full-term deliveries with macrosomic neonates, carried out in a public hospital in the Valley of the Apurímac, Ene and Mantaro rivers, Peru. The study variables: maternal age, pre-pregnancy body mass index, number of pregnancies, gestational age at delivery, and route of delivery. Spearman's Rho and Pearson's correlation coefficients were used, both with 95% confidence intervals and 5% error. Results Fetal weight estimation and macrosomia correlated with uterine height (Pearson's R 0.05). Among the maternal characteristics associated with macrosomic neonates, pregestational obesity (Rho = 0.009) and multigestational condition (Rho = 0.04) were found. The estimation of fetal weight greater than 4000 g had a higher percentage of success (26.3%) by obstetric ultrasound. Conclusion obstetric ultrasound showed a higher correlation than uterine height with the diagnosis of fetal macrosomia.

Assessing the duration of obstetric analgesia and the time elapsed between analgesia and delivery. Observational trial / Evaluación de la duración de la analgesia obstétrica y del tiempo entre la analgesia y el parto. Estudio observacional

Abstract Introduction: The duration of labor and the immediate puerperium are affected by obstetric and maternal-fetal factors. Interventions to provide obstetric analgesia may prolong the hospital stay. Objective: To characterize the procedure for obstetric analgesia and describe the time elapsed between analgesia and delivery and postpartum surveillance in healthy mothers. Methods: Observational, descriptive trial. The time elapsed between analgesia and delivery, and postpartum surveillance were measured in healthy pregnant women with vaginal delivery and a prescription of a neuraxial analgesia technique. Results: 226 patients were included. The mean time elapsed between analgesia an delivery was 4 hours (IQR 3-7). 50.7 % (n=114) received early analgesia (neuraxial technique with ≤ 4 centimeters of cervical dilatation), of which 48.2 % (n = 109) experienced a duration of analgesia until delivery longer than expected. The mean cervical dilatation at the time of the neuraxial approach was 4 centimeters (IQR 4-6) and the epidural technique was the most frequently used - 92.9 % (n = 210). The mean postpartum surveillance was 20 hours (IQR 15-27). Conclusions: Half of the patients included received early analgesia and around fifty percent of them took longer than expected in completing delivery. The postpartum surveillance time was consistent with the provisions of the Ministry of Health and with the current trend of a short postpartum surveillance aimed at early hospital discharge and the benefits thereof.

Resumen Introducción: La duración del trabajo de parto y del puerperio inmediato se afectan por factores obstétricos y maternofetales. Las intervenciones para brindar analgesia obstétrica pudieran prolongar el tiempo total de estancia hospitalaria. Objetivo: Caracterizar el procedimiento de analgesia obstétrica y describir los tiempos entre analgesia y parto y vigilancia posparto en maternas sanas. Métodos: Estudio descriptivo observacional. Se midieron los tiempos entre analgesia y parto y vigilancia posparto en gestantes sanas, cuya vía final del parto fuera vaginal con indicación y aplicación de alguna técnica de analgesia neuroaxial. Resultados: Se incluyeron 226 pacientes. La mediana del tiempo de analgesia hasta el parto fue de 4 horas (RIC 3-7); el 50,7 % (n = 114) recibió analgesia temprana (técnica neuroaxial a ≤ 4 centímetros de dilatación cervical), de las cuales el 48,2 % (n = 109) tuvo un tiempo de analgesia hasta el parto mayor al esperado. La mediana de dilatación cervical al momento del abordaje del neuroeje fue de 4 centímetros (RIC 4-6) y la técnica epidural fue la más frecuente, 92,9 % (n = 210). La mediana de tiempo de vigilancia posparto fue de 20 horas (RIC 15-27). Conclusiones: La mitad de las pacientes incluidas recibió analgesia temprana y cerca de la mitad tardó más de lo esperado en finalizar su gestación. El tiempo de vigilancia posparto fue acorde con lo establecido por el Ministerio de Salud y con la tendencia actual de una vigilancia posparto corta que apunte a un alta temprana y sus beneficios.

Objective To analyze the reports of obstetric violence registered in the Federal Prosecution Service of Amazonas in order to map health institutions of Amazonas involved in obstetric violence; to indicate techniques considered by women as violent; and to survey professional categories denounced as perpetrators of obstetric violence. Method This is a quantitative, exploratory and documentary study, carried out from January to April 2018 at the Federal Prosecution Service of Amazonas state. Data were processed and analyzed using Excel and Word and were presented in tables. Results 43 reports of obstetric violence from 2008 to 2018 were analyzed, making it possible to detect twelve different ways of reporting; mapping thirteen health institutions and 29 techniques considered violent; as well as identifying eight professional specialties denounced. Conclusion It has been observed that obstetric violence identified occurred in both public and private institutions; caused by different health professionals, especially doctors and nurses; using different techniques, actions and/or attitudes, mainly those in the field of the professional-user relationship. Thus, it has been noticed that the complaints reported do not refer only to the category of institutional violence, they also include practices of violence within the scope of the professional-user relationship.

Efficacy of Doula delivery combined with painless delivery and its effects on pregnancy outcome / 中国基层医药

Objective:To investigate the efficacy of Doula delivery combined with painless delivery and its effects on pregnancy outcome.Methods:A total of 150 parturient women who underwent delivery in the First People's Hospital of Yongkang from June 2019 to June 2020 were included in this study. They were randomly assigned to undergo either conventional delivery (control group, n = 75) or Doula delivery combined with painless delivery (observation group, n = 75). Analgesic effect, mode of delivery, duration of labor and pregnancy outcome as well as mood score before and after intervention were compared between the two groups. Results:Total analgesia-effective rate in the observation group was significantly higher than that in the control group [100.00% (75/75) vs. 65.33% (49/75), χ2 = 31.45, P < 0.05]. Vaginal delivery rate in the observation group was significantly higher than that in the control group [84.00% (63/75) vs. 66.67% (50/75), χ2 = 6.60, P < 0.05]. The length of the first stage of labor, the second stage of labor, the third stage of labor and total labor length in the observation group were (398.42 ± 35.41) minutes, (43.65 ± 5.78) minutes, (8.36 ± 1.08) minutes and (450.87 ± 37.98) minutes, which were significantly shorter than those in the control group [(543.21 ± 47.87) minutes, (76.73 ± 16.56) minutes, (9.76 ± 1.23) minutes, (629.34 ± 45.26) minutes, t = 21.05, 16.33, 7.40, 26.15, all P < 0.05]. The incidence of neonatal asphyxia, fetal distress and postpartum hemorrhage in the observation group were [1.33% (1/75), 2.67% (2/75) and 2.67% (2/75), respectively, which were significantly lower than those in the control group [13.33% (10/75), 17.33% (13/75), 18.67% (14/75), χ2 = 7.94, 8.96, 10.07, all P < 0.05]. Self-rating Anxiety Scale score and Self-Rating Depression Scale score in the observation group were (43.25 ± 4.28) points and (40.28 ± 3.45) points, which were significantly lower than those in the control group [(52.12 ± 3.95) points, (47.79 ± 3.72) points, t = 13.18, 12.81, both P < 0.05). Conclusion:Doula delivery combined with painless delivery can relieve women's emotional changes, alleviate pain, shorten labor duration, and improve pregnancy outcomes.

Combined application of intraspinal analgesia, bilateral pudendal nerve block anesthesia and modified perineal protection in midwifery / 中国基层医药

Objective:To investigate the clinical efficacy of intraspinal analgesia, pudendal nerve block anesthesia and modified perineal protection in combination in midwifery.Methods:A total of 160 primiparous women who were subjected to full-term vaginal delivery in Suqian Hospital of Nanjing Drum Tower Hospital Group between January 2019 and January 2021 were included in this study. They were randomly assigned to undergo either bilateral pudendal nerve block combined with modified perineal protection (control group, n = 80) or intraspinal analgesia, pudendal nerve block anesthesia and modified perineal protection in combination (observation group, n = 80). Each clinical index was compared between the control and observation groups. Results:Duration of labor in the observation group was significantly shorter than that in the control group [(7.23 ± 2.11) hours vs. (9.35 ± 3.79) hours, t = 4.27, P < 0.05). Cesarean section rate in the observation group was significantly lower than that in the control group [8.7% (7/80) vs. 52.5% (42/80), χ 2 = 17.18, P < 0.05]. Incidence of perineal tears in the observation group was significantly lower than that in the control group [8.7% (7/80) vs. 32.5% (26/80), χ 2 = 15.48, P < 0.05]. Third-degree perineal tears occurred in neither group. Time of postpartum off-bed ambulation and length of postpartum hospital stay in the observation group were (1.37 ± 0.13) days and (3.22 ± 0.31) days, respectively, which were significantly shorter than those in the control group [(2.52 ± 0.22) days, (5.23 ± 0.62) days, t = 25.90, 25.94, both P < 0.05). The incidence of complications in the observation group was significantly lower than that in the control group [7.5% (6/80) vs. 23.7% (19/80), χ 2 = 8.01, P < 0.05]. There were no significant differences in incidence of neonatal asphayxia, 2-hour postpartum hemorrhage and postpartum hemorrhage between the two groups (all P > 0.05). Conclusion:During midwifery of full-term vaginal delivery, combined application of intraspinal analgesia, bilateral pudendal nerve block anesthesia and modified perineal protection can shorten duration of labor and decrease cesarean section rate.

According to the random number table, they were divided into the observation group (50 cases) and the control group (50 cases). Parturients in the observation group received a modified epidural catheter for labor analgesia, and parturients in the control group received conventional epidural analgesia. The complications of epidural vascular injury, difficulty in catheterization, multiple catheterization, loss of catheter resistance, urinary retention, intrauterine distress, neonatal asphyxia, postpartum hemorrhage, Apgar score, maternal and neonatal outcomes were compared between the two groups.Results:The rate of epidural vascular injury, difficulty in catheter placement, multiple catheter placement and disappearance of catheter resistancein the observation group were lower than those in the control group: 2.0%(1/50) vs. 14.0%(7/50), 2.0%(1/50) vs. 16.0%(8/50), 0 vs. 8.0% (4/50), 8.0% (4/50) vs. 24.0% (12/50), χ2 = 4.89, 5.98, 4.17, 4.76, P<0.05. The rate of urinary retention, intrauterine distress and neonatal asphyxia in the observation group were lower than those in the control group: 4.0%(2/50) vs. 16.0%(8/50), 2.0%(1/50) vs. 14.0%(7/50), 0 vs. 8.0%(4/50), χ2 = 4.00, 4.89, 4.17, P<0.05. Conclusions:Improved epidural catheter delivery analgesia for patients with scarred uterus can achieve significant results, effectively reduce the incidence of vascular injury, and improve the maternal and infant outcome.

Epidural analgesia failure followed by intracranial subdural hematoma: a case report / 中华围产医学杂志

We report the diagnosis and treatment of a rare case of epidural analgesia failure followed by postpartum subdural hematoma. The patient underwent vaginal delivery under epidural analgesia at 32 +6 gestational weeks due to threatened premature labor, during which an unexpected dural rupture occurred. She gave no history of headache and there was no obvious abnormality during the pregnancy. However, on postpartum day 4, the patient complained of headache that could not be relieved when supine, but without any other neurological symptoms. A prompt cranial CT examination showed a left frontotemporal subdural hematoma. After conservative management with intravenous drip of mannitol, re-examination of cranial CT showed that the left frontotemporal subdural hematoma was mostly absorbed and the patient was discharged on postpartum day 18. The patient was healthy during follow up. Intracranial subdural hematoma after dural puncture is a rare and serious complication that requires early recognition and treatment.

Evaluation of efficacy of intravenous nalbuphine before epidural labor analgesia in inhibiting uterine contraction pain in primiparae / 中华麻醉学杂志

Objective:To assess the value of nalbuphine intravenously injected before epidural labor analgesia in inhibiting uterine contraction pain in primiparae.Methods:A total of 140 expectant primiparae who were suitable and willing to receive epidural labor analgesia with a singleton fetus in vertex presentation, aged 20-40 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅱ, with their cervical dilation of 2-3 cm, were divided into nalbuphine group (N group) and routine control group (C group), with 70 cases in each group.Group N received intravenous injection of nalbuphine 0.1 mg/kg (in normal saline 5 ml) at 10 min before epidural puncture, while group C received intravenous injection of the equal volume of normal saline at 10 min before epidural puncture.The epidural puncture-related items including the intensity of pain (Numeric Rating Scale [NRS] scores) and degree of sedation-agitation (Riker sedation agitation scores) during uterine contraction, duration of epidural procedure, parturients′ satisfaction with epidural puncture, successful epidural catheterization at first attempt and complications (nerve paraesthesia and inadvertent intravascular punctures) were recorded.Results:Compared with group C, the NRS scores and Riker scores for uterine contraction pain were significantly decreased during epidural procedure ( P<0.05), with NRS score <6 and Riker sedation agitation scores of 4, the duration of epidural puncture was shortened, the success rate of epidural puncture at first attempt was increased(51%/70%), and the incidence of nerve paraesthesia and inadvertent intravascular puncture was decreased(17%/6%, 14%/4%), and the parturients′ satisfaction with epidural puncture was increased in group N ( P<0.05). Conclusions:Nalbuphine 0.1 mg/kg intravenously injected before epidural labor analgesia can safely and effectively reduce uterine contraction pain without limb agitation, which is helpful in implementating epidural puncture in primiparae.

Efficacy of long-interval programmed intermittent epidural bolus during incubation period for labor analgesia / 中华麻醉学杂志

Objective:To evaluate the efficacy of long-interval programmed intermittent epidural bolus (PIEB) during the incubation period for labor analgesia.Methods:Seventy-eight nulliparous parturients who were at full term with a singleton fetus in vertex presentation, aged 22-35 yr, with body mass index of 18.0-30.0 kg/m 2, of American Society of Anesthesiologists physical statusⅠorⅡ, were divided into 2 groups ( n=39 each) using a random number table method: routine epidural bolus using a stepwise approach group (C group) and long-interval PIEB group (L group). Epidural puncture was performed at L 2, 3, and the analgesia solution was 0.1% ropivacaine and 0.5 μg/ml sufentanil in the two groups.The parturients in group C received 8 ml pulse dose per hour during the incubation period (cervical dilatation <3 cm), and 10 ml pulse dose per hour during the active phase (cervical dilatation ≥3 cm). In group L, the first pulse dose was 10 ml during the incubation period, 1.5 h later the anesthesia plane was detected, and 10 ml pulse dose was immediately given when the plane was lower than T 10, otherwise it was reevaluated 15 min later.After the interval time reached 2 h, a pulse dose 10 ml was given regardless of whether the plane was lower than T 10, and the pulse dose 10 ml was given at 1 h interval during the active phase.The numerical rating scale scores were recorded when the cervical dilatation was 3, 6 and 10 cm, and at the time of baby delivery.The duration of labor, total consumption of analgesics, and Bromage grade of lower extremities were recorded.The Apgar score <7 at 1 and 5 min after birth was recorded.The maternal adverse reactions and scores for satisfaction with analgesia were also recorded. Results:Thirty puerperae were finally enrolled in each group.The first stage of labor and total duration of labor were significantly shortened, and the total consumption of analgesics was decreased in group L ( P<0.01). There were no significant differences in the numerical rating scale scores at each time point, duration of second and third stages of labor, Bromage grade of lower extremities, incidence of adverse reactions, score for satisfaction with analgesia, and incidence of Apgar score < 7 after birth between the two groups ( P>0.05). Conclusions:When PIEB is used for labor analgesia, prolonging the infusion interval time of epidural bolus to 1.5-2.0 h during the incubation period can produce satisfactory analgesic effect and further decrease the consumption of analgesics and reduce the influence on labor stages when compared with administration using a stepwise approach.

Optimization efficacy of nalbuphine mixed with ropivacaine for epidural labor analgesia in primiparas: comparison with sufentanil mixed with ropivacaine / 中华麻醉学杂志

Objective:To evaluate the optimization efficacy of ropivacaine mixed with nalbuphine for epidural labor analgesia through comparison with ropivacaine mixed with sufentanil in primiparas.Methods:Four hundred and forty primiparas with a singleton fetus in vertex presentation without abnormal fetus, aged 19-36 yr, at 37-42 weeks of gestation, who were suitable and volunteered to receive epidural labor analgesia, were selected and randomly divided into observation group (NR group, n=220) and conventional group (C group, n=220).Epidural labor analgesia solution contained nalbuphine 40 mg and ropivacaine 120 mg in 150 ml of normal saline in group NR.Epidural labor analgesia solution contained sufentanil 50 μg and ropivacaine 120 mg in 150 ml of normal saline in group C. The analgesia pump was set up to deliver a 5 ml bolus dose with a 20-min lockout interval, programmed intermittent bolus 10-15 ml/h and background infusion at 2 ml/h after an initial dose of 15 ml to maintain VAS score <3.The length of labor, adverse reactions during labor analgesia, neonatal Apgar score, parameters of umbilical artery blood gas analysis and neonatal behavioral neurological assessment score were recorded. Results:Compared with group C, the incidence of urinary retention, pruritus, nausea and vomiting and fever at birth was significantly decreased in group NR ( P<0.05).The duration of the first and second stages of labor, neonatal Apgar score, pH value of umbilical artery blood, lactate concentrations, and neonatal behavioral neurological assessment score were within the normal range in both groups, and there was no significant difference between the two groups ( P>0.05). Conclusions:Compared with conventional medication, nalbuphine mixed with ropivacaine has the same efficacy when used for epidural labor analgesia in primiparas, but it has a certain optimization efficacy in terms of safety.

Anesthetic management of a parturient with Marfan syndrome scheduled for cesarean section: case report and review of literature / Manejo anestésico de una parturienta con síndrome de Marfan programada para cesárea: informe de un caso y revisión de la literatura

Abstract: Introduction: Marfan syndrome is an inherited disorder that affects connective tissue. Case: We report the anesthetic management of a parturient with Marfan syndrome scheduled for an elective C-section. Successful use of a combined spinal-epidural technique was used to provide neuraxial anesthesia; however, she presented an unfavorable evolution due to maternal sepsis. Likewise, a literature review of combined spinal-epidural anesthesia for C-sections in Marfan syndrome pregnant women was performed. Conclusion: Anesthetic management of parturients affected by Marfan syndrome during the cesarean section can be challenging. Strict blood pressure control during the intraoperative period has cornerstone importance. Likewise, neuraxial techniques have a significant percentage of failure in these patients.

Resumen: Introducción: El síndrome de Marfan es un desorden hereditario que afecta el tejido conectivo. Caso: Reportamos el manejo anestésico de una parturienta con síndrome de Marfan programada para una cesárea electiva. Para administrar anestesia neuroaxial se utilizó un bloqueo combinado espinal-epidural; sin embargo, la paciente presentó una evolución desfavorable debido a sepsis materna. Asimismo, se realizó una revisión de la literatura del uso de esta técnica anestésica para cesárea en gestantes con síndrome de Marfan. Conclusión: El manejo anestésico de parturientas afectadas por este síndrome puede ser complicado. El control estricto de la presión arterial durante el intraoperatorio tiene importancia fundamental. Además, las técnicas neuroaxiales tienen un porcentaje significativo de fallo en estas pacientes.
