Manejo anestésico de las pacientes embarazadas tetrapléjicas durante el parto: una revisión sistemática / Anaesthetic management of tetraplegic pregnant patients during child delivery: A systematic review

Introducción: El embarazo en pacientes con lesión de la médula espinal tiene unas características específicas. Sin embargo, las guías para orientar su manejo son escasas. Métodos: Se realizó una revisión sistemática de la literatura sobre el manejo anestésico durante el parto de pacientes embarazadas con lesión de la médula espinal cervical. Resultados: Se observó una mayor incidencia de parto prematuro y cesárea. El manejo anestésico fue diverso, aunque la mayoría de las pacientes embarazadas recibieron analgesia epidural. Los síntomas de disreflexia autónoma se observaron en el 51% de las mujeres. Conclusión: El manejo adecuado de estas pacientes podría reducir posiblemente la tasa de cesáreas y partos prematuros, y minimizar las complicaciones comunes, reduciendo al mismo tiempo los costes. Se recomienda una derivación precoz a la consulta de anestesiología y un enfoque multidisciplinario.(AU)

Introduction: Pregnancy in spinal cord injured patients has specific issues that must be carefully addressed. However, guidelines for their management are scarce. Methods: A systematic review of the literature regarding the anaesthetic management during delivery of pregnant patients with cervical spinal cord injury was performed on the electronic databases of PubMed (Medline) and Cochrane. Results: A higher incidence of preterm birth and caesarean delivery were seen. Anaesthetic management was diverse, although most pregnant patients received epidural analgesia. Autonomic dysreflexia symptoms were present in 51% of pregnancies. Conclusion: Timely management of these patients could possibly reduce caesarean and preterm delivery rates, avoid or minimize common complications, as well as reduce costs. An early reference to anaesthesiology consultation and a multidisciplinary approach is recommended.(AU)

Anaesthetic management of tetraplegic pregnant patients during child delivery: A systematic review.

BACKGROUND: Pregnancy in spinal cord injured patients has specific issues that must be carefully addressed. However, guidelines for their management are scarce. METHODS: A systematic review of the literature regarding the anaesthetic management during delivery of pregnant patients with cervical spinal cord injury was performed on the electronic databases of PubMed (Medline) and Cochrane. RESULTS: Twenty-two papers were included. A higher incidence of preterm birth and caesarean delivery were seen. Anaesthetic management was diverse, although most pregnant patients received epidural analgesia. Autonomic dysreflexia symptoms were present in 51% of pregnancies. CONCLUSION: Timely management of these patients could possibly reduce caesarean and preterm delivery rates, avoid or minimize common complications, as well as reduce costs. An early reference to anaesthesiology consultation and a multidisciplinary approach is recommended.

¿Han cambiado los conceptos de analgesia obstétrica en los últimos 100 años? / Have the concepts of obstetric analgesia changed in the last 100 years?

Objetivos: Comparar los conceptos y métodos de analgesia obstétrica actual con los existentes hace 100 años, cuando se publicaron por primera vez Anesthesia & Analgesia (1922) y British Journal of Anaesthesia (1923), que son las dos primeras revistas de anestesia publicadas de forma independiente.Material y métodos: Identificamos y analizamos todos los artículos relacionados con la analgesia obstétrica publicados en estas revistas durante los años 1922 y 1923, y los comparamos con la práctica clínica actual. También buscamos en estos números referencias indirectas a la atención prestada a la analgesia obstétrica en las reuniones científicas de la época.Resultados: En el primer número de Anesthesia & Analgesia que aparece en agosto de 1922, 3 de los 8 artículos publicados están relacionados exclusivamente con la anestesia y analgesia obstétrica, y entre 1922 y 1923 encontramos un alto número de artículos y referencias. El análisis de estos artículos publicados hace un siglo permite objetivar el interés de la época por los resultados, la comparación entre los diferentes métodos anestésicos, la seguridad y la divulgación del conocimiento científico. Son habituales las referencias a la mortalidad, a las complicaciones, al confort y la satisfacción de la paciente, a la influencia de la analgesia obstétrica en la duración del parto, así como al ahorro de tiempo y de gases anestésicos. Resulta obvio que la metodología de investigación actual no puede compararse con la de hace 100 años. Pero existen numerosos aspectos científicos que sentaron algunas de las bases de la investigación actual en obstetricia, entre los que destacan la recogida de amplias series de pacientes durante largos periodos de tiempo, la mención expresa a la publicación de resultados tanto favorables como desfavorables...(AU)

Objectives: To compare current obstetric analgesia concepts and methods with those existing 100 years ago, when Anesthesia & Analgesia (1922) and British Journal of Anaesthesia (1923), the first two independently published anesthesia journals, were first published.Methods: We identified and analyzed all articles related to obstetric analgesia published in these journals during the years 1922 and 1923 and compared them with current clinical practice. We also searched these issues for indirect references to the attention given to obstetric analgesia at scientific meetings of the time.Results: In the first issue of Anesthesia & Analgesia, appearing in August 1922, 3 of the 8 articles published are related exclusively to obstetric anesthesia and analgesia, and between 1922 and 1923 we found a high number of articles and references. The analysis of these articles published a century ago allows us to objectify the interest of the time in the results, the comparison between different anesthetic methods, safety and the dissemination of scientific knowledge. References to mortality, complications, patient comfort and satisfaction, the influence of obstetric analgesia on the duration of labor, as well as savings in time and anesthetic gases are common.It is obvious that today's research methodology cannot be compared with that of 100 years ago. But there are many scientific aspects that laid some of the foundations of current research in obstetrics, including the collection of large series of patients over long periods of time, the express mention of the publication of both favorable and unfavorable results, the references not only to cost but also to cost-effectiveness, as well as the use of specific parameters to measure not only results but also patient satisfaction.Conclusions: It is evident that over the years the outcomes in the practice of anesthesiology have improved, but also that many concepts remain the same 100 years later...(AU)

[Cultural myths on the use of analgesia in labor: A cross-sectional study in Nigerian women]. / Mitos culturales sobre el uso de la analgesia en el trabajo de parto: estudio transversal en mujeres nigerianas.

OBJECTIVE: Pain is termed as a subjective phenomenon, however almost all women acknowledge that labor pain is the most severe form of pain a woman experiences in her lifetime. Obstetric analgesia is underutilized in developing countries due to cultural myths and taboos. Hence, the present study aims to identify Nigerian women's knowledge of labor analgesia and to explore what myths and factors hinder with the use of analgesia in labor. METHOD: A quantitative descriptive cross-sectional design was adopted in this study. The population of the study predominantly consisted of pregnant women from the «Yoruba ethnic group¼. An adapted semi-structured questionnaire was used to obtain data from participants from selected Health Care Centers in Ekiti state, Nigeria. The collected data was analyzed using a descriptive and inferential statistics and was represented in form of tables and charts with level of significance set at p ≤ 0.05. RESULTS: A total of 236 respondents were included in the study (n = 236). Findings from this study revealed that, the participants showed very poor knowledge on labor pain management strategies, with only 26.3% being aware of pain management strategies used in relieving labor pain. An elevated number of the participants (56.8%) believed that labor pain should not be relieved with the use of drugs, strongly agreeing that analgesia was «a sign ofweakness¼ (57.2%). Also, more than half (51.7%) of participants had fears that pain relief administered during labor can cause harm to the unborn baby. Belief that experiencing labor pain completes one's motherhood (49.6%), Religion (50.4%) and Culture (54.5%), were reported as factors influencing the uptake/acceptance of labor analgesia among participants. Furthermore statistical significant association was found between educational level of participants and knowledge of labor analgesia among participants (p value = 0.000; p ≤ 0.05). CONCLUSIONS: Cultural myths on the use of analgesia exist among participants. It is suggested that women-centered education should be targeted toward eliminating these myths and increasing awareness about labor analgesia.

Mitos culturales sobre el uso de la analgesia en el trabajo de parto: estudio transversal en mujeres nigerianas / Cultural myths on the use of analgesia in labor: A cross-sectional study in Nigerian women

Objetivo: El dolor se califica como un fenómeno subjetivo, sin embargo, casi todas las mujeres reconocen que el dolor de parto es la forma más severa de dolor que una mujer experimenta en su vida. La analgesia obstétrica está infrautilizada en los países en desarrollo debido a mitos y tabúes culturales. Por lo tanto, el presente estudio pretende identificar los conocimientos de las mujeres nigerianas sobre la analgesia del parto y explorar qué mitos y factores dificultan el uso de la analgesia en el parto. Método: En este estudio se adoptó un diseño cuantitativo descriptivo transversal. La población a estudio consistió predominantemente en mujeres embarazadas de la «etnia Yoruba». Se utilizó un cuestionario semiestructurado adaptado para obtener datos de las participantes de los centros de salud seleccionados en el estado de Ekiti, Nigeria. Los datos recogidos se analizaron mediante estadística descriptiva e inferencial y se representaron en forma de tablas y gráficos. El nivel de significación estuvo fijado en p ≤ 0,05. Resultados: Un total de 236 encuestadas fueron incluidas en el estudio (n = 236). Los resultados de este estudio revelaron que las participantes tenían un conocimiento muy pobre de las estrategias de tratamiento del dolor del parto, ya que solo 26,3% conocía las estrategias de tratamiento del dolor utilizadas para aliviar el dolor del parto. Un elevado número de las participantes (56,8%) creía que el dolor del parto no debía aliviarse con el uso de fármacos, estando muy de acuerdo en que la analgesia era «un signo de debilidad» (57,2%). Asimismo, más de la mitad (51,7%) de las participantes temían que el alivio del dolor administrado durante el parto pudiera causar daños al feto. La creencia de que experimentar el dolor del parto completa la maternidad (49,6%), la religión (50,4%) y la cultura (54,5%) se señalaron como factores que influyen en la aceptación de la analgesia del parto entre las participantes.(AU)

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. Apresentamos o caso de uma paciente cuja complicação foi a ruptura e retenção de um fragmento de cateter epidural durante sua colocação para analgesia do parto.

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.

Impacto del uso de analgesia peridural controlada por la paciente en la disminución del dolor durante el trabajo de parto en un hospital del suroccidente colombiano / Impact of the use of patient-controlled epidural analgesia on pain reduction during labor in a hospital in southwestern colombia

Introducción: La analgesia epidural controlada por la paciente (PCA) provee flexibilidad al permitir acomodar la analgesia de acuerdo con las necesidades crecientes del dolor a medida que progresa el trabajo de parto (TP). El propósito de este estudio es objetivar el impacto en el alivio del dolor y satisfacción materna en pacientes en TP con analgesia PCA.Pacientes y métodos: Estudio descriptivo prospectivo realizado en el segundo semestre del 2020. Se incluyeron gestantes con embarazo único con escala verbal numérica (EVN) mayor a 3 y se excluyeron a las pacientes con contraindicaciones para inserción de catéter. Posterior a la inserción, se valoró el dolor y se entregó un cuestionario para calificar el dolor a los 15 min y en el expulsivo.Resultados: La población estaba constituida por mujeres jóvenes, el 72 % con embarazo a término. El catéter peridural se insertó en la fase latente del trabajo de parto en el 53,4 % de los casos. Al momento de la inserción del catéter, la mediana de dolor fue de 8 (6-10), a los 15 minutos 2 (0-4) y en el expulsivo 5 (3-8). El 75 % de las maternas refirieron estar muy satisfechas y el 19 % satisfechas; un 3 % indicaron estar poco satisfechas y el 1 % restante, insatisfechas. La prevalencia náusea y vómito fue del 16 % y 15 %, respectivamente.Conclusiones: PCA como estrategia analgésica durante el trabajo de parto a través de bolos intermitentes a demanda logró un adecuado control del dolor en los primeros minutos posterior a la inserción sin un control óptimo durante el expulsivo, sin embargo, se obtuvo una satisfacción materna global alta.(AU)

Introduction: Patient-controlled analgesia (PCA) allows patients to accommodate analgesia according to increasing pain needs as labor progresses. This study aims to objectify the impact on pain relief and maternal satisfaction in labor patients with PCA analgesia.Patients and methods: A prospective descriptive study was carried out in the second semester of 2020. Pregnant women with a singleton pregnancy with a numerical rating scale (NRS) greater than three were included, and patients with contraindications for catheter insertion were excluded. After insertion, pain was assessed, and a questionnaire was given to rate pain at 15 min and during expulsion.Results: The population consisted of young women, 72 % of whom were pregnant at term. The epidural catheter was inserted in the latent phase of labor in 53.4 % of cases. At the time of catheter insertion, the median pain was 8 (6-10), at 15 minutes 2 (0-4), and expulsion 5 (3-8). Seventy-five percent of the mothers reported being very satisfied and 19 % satisfied; 3 % reported being slightly satisfied, and the remaining 1 % dissatisfied. The prevalence of nausea and vomiting was 16 % and 15 %, respectively.Conclusions: PCA as an analgesic strategy during labor through intermittent boluses on-demand achieved adequate pain control in the first minutes after insertion without optimal control during expulsion. However, high overall maternal satisfaction was obtained.(AU)

Analgesia epidural: actitud y calidad percibida por las puérperas en el Hospital Universitario Materno Infantil de Canarias / Epidural analgesia: attitude and quality perceived by puerperal women at the Hospital Universitario Materno Infantil de Canarias

Objetivo: Identificar las actitudes y la calidad subjetiva percibida por las mujeres después del uso de analgesia epidural en el parto. Metodología: Estudio transversal, observacional, descriptivo y analítico realizado en el Hospital Universitario Materno Infantil de Gran Canaria, donde la población de estudio fueron las puérperas que recibieron analgesia epidural durante el parto entre agosto y octubre de 2019. Se utilizaron un muestreo consecutivo no probabilístico y un cuestionario autoadministrado. Se realizaron un análisis descriptivo de las variables y un análisis inferencial para explorar la asociación entre diferentes variables. Resultados: La muestra final estuvo constituida por 354 mujeres. Las mujeres consideraron que la información recibida por las matronas era la más importante (57,6%), y el 20,3% percibió un retraso en la administración de analgesia epidural después de su solicitud. Se obtuvo una puntuación media respecto a la satisfacción global materna de 24,45 (desviación estándar= 4,97; máxima 28; mínima 0). Se encontró una relación estadísticamente significativa entre la satisfacción global y el nivel educativo (p= 0,019*), y entre la lectura y el entendimiento previo del consentimiento informado y la satisfacción global materna (p <0,001*). La percepción de demora en la administración influye de forma negativa en la satisfacción (p= 0,003*). Conclusiones: Un número elevado de mujeres que inicialmente no se planteaban la analgesia epidural en el parto acabó optando por ella, con un nivel alto de satisfacción y calidad percibida después de su uso. (AU)

Objective: To identify labouring women’s attitudes and subjective quality after the use of epidural analgesia. Methodology: Observational, descriptive analytical cross-sectional study at the Mother and Children’s University Hospital of Gran Canaria, with a study population of postnatal women who received epidural analgesia during delivery between August and October 2019. A non-probabilistic consecutive sample and a self-administered questionnaire were used. A descriptive analysis of the collected variables and an inferential analysis was performed to explore the association between different variables. Results: From a sample of 354 women. Women considered the information received by midwives more important (57.6%) and 20.3% perceived a delay in the administration of epidural analgesia after their request. An average score of 24,45 regarding maternal global satisfaction was obtained (SD= 4.97; maximum 28; minimum 0). A statistically significant relationship was found between global satisfaction and educational level (p= 0.019*) and between reading and prior understanding of informed consent and overall maternal satisfaction (p <0.001*). Delay perception in the administration of the epidural negatively influenced satisfaction (p= 0.003*). Conclusions: A high number of women who initially did not consider epidural analgesia in childbirth end up opting for it, the level of satisfaction and quality perceived after its use being high.

Meningitis tras técnica combinada raquídea-epidural para analgesia del parto: reporte de un caso / Case report of meningitis after combined spinal-epidural analgesia for labor

La meningitis pospunción es una complicación importante y poco frecuente de la anestesia neuroaxial. Describimos el caso de una paciente que ingresa para inducción del parto. Se realiza técnica espinal-epidural para analgesia del parto. Cursando 48 h de puerperio instala cefalea intensa, fotofobia y fiebre. No focalidad neurológica. Sin rigidez de nuca. Al examen, restos cavitarios que impresionan fétidos. Se plantea endometritis puerperal iniciando tratamiento antibiótico. Dado la persistencia del cuadro clínico se plantea punción lumbar para confirmación diagnóstica mediante análisis de líquido cefalorraquídeo; siendo éste turbio, por lo cual ingresa a cuidados intensivos con diagnóstico de meningitis aguda. Bacterióloga informa a los 10 días que el cultivo desarrolla estreptococo mitis oralis. La importancia esta dada porque la meningitis puede ser potencialmente devastadora si no se realiza un diagnóstico y tratamiento tempranos, existiendo medidas que se pueden adoptar para prevenir esta complicación.

Post-puncture meningitis is an important and rare complication of neuraxial anesthesia. We describe case of patient who is admitted for induction of labor. A spinal-epidural technique is performed for labor analgesia. During 48 hours of puerperium, she installed intense headache, photophobia and fever. No neurological focus. No stiff neck. On physical exam, cavitary remains that appear fetid. Puerperal endometritis arises starting antibiotic treatment. Given the persistence of the clinical picture, lumbar puncture is considered for diagnostic confirmation by analysis of cerebrospinal fluid; This being cloudy, for which he was admitted to Intensive Care with a diagnosis of acute meningitis. Bacteriologist reports 10 days later develops streptococcus mitis oralis. The importance is given because meningitis can be potentially devastating if early diagnosis and treatment is not performed, and there are measures that can be taken to prevent this complication.

Obstetric analgesia in labor and its association with neonatal outcomes / Analgesia obstétrica en el trabajo de parto y su asociación con resultados neonatales / Analgesia obstétrica no trabalho de parto e sua associação com desfechos neonatais

ABSTRACT Objetives: To investigate the association between analgesia during labor and occurrence of neonatal outcomes. Methods: Retrospective cohort study with medical records of 850 parturient. The exposure variable of interest was receiving pharmacological analgesia during labor and neonatal outcomes were: one- and five-minute Apgar, resuscitation maneuvers and referral of the newborn to Neonatal ICU. A logistic regression was carried out to obtain Odds Ratios and 95% confidence interval, with adjustment for confounding factors. Results: Among the women studied, 35% received analgesia and this use was associated with a greater chance of neonatal outcomes such as one-minute Apgar < 7 (p <0.0001), resuscitation maneuvers (p <0.001) and referral to the Neonatal ICU (p = 0.004), mostly were among low-risk pregnant women, even after adjustments. Conclusions: The use of pharmacological analgesia during labor is associated with one-minute Apgar < 7, resuscitation maneuvers and referral to the Neonatal ICU.

Analgesia en trabajo de parto / Analgesia in labour

Resumen: El dolor que experimentan las mujeres durante el trabajo de parto es considerado uno de los dolores más severos e intensos. La Asociación Internacional para el Estudio del Dolor (IASP) declaró al 2007 como el «Año Global Contra el Dolor en la Mujer¼, enfatizando la importancia que tiene el tratamiento del dolor y su impacto en la salud pública si este dolor es mal tratado y descuidado: se ha reportado un incremento alarmante en la incidencia de dolor agudo postparto y postcesárea de moderado a severo, que ha sido asociado con síndrome de estrés postraumático, depresión postparto y dolor persistente con datos de cronificación. El Colegio Americano de Ginecología y Obstetricia (ACOG), la Sociedad de Anestesia Obstétrica y de Perinatología (SOAP), la Sociedad Americana de Anestesiología (ASA) y la Asociación Internacional Para el Estudio del Dolor (IASP) han generado el modelo para manejo de dolor agudo universal (para ver el artículo completo visitehttp://www.painoutmexico.com).

Abstract: The pain that women experience during labor is considered one of the most severe and intense pains. The International Association for the Study of Pain (IASP) declared the year 2007 as «The Global Year Against Pain in Women¼, emphasizing the importance of treating pain in pregnant women in relation to its impact on public health if this pain is poorly treated: there is an alarming increase in the incidence of moderate to severe acute pain postpartum and post-cessation that has been associated with in post-traumatic stress syndrome, postpartum depression and pain persistent with data cronification. The American College of Obstetricians and Gynecologist (ACOG), the American Society of Anesthesiologists (ASA), the Obstetric Anesthesia and Society for Obstetric Anesthesia and Perinatology (SOAP) and the International Association for the Study of Pain (IASP) have generated a model for pain management that provides universal standard care (full version visithttp://www.painoutmexico.com ) .

Knowledge, attitude and practice regarding pharmacological methods of labor analgesia / Conhecimento, atitude e prática em relação aos métodos farmacológicos de analgesia de parto

ABSTRACT BACKGROUND AND OBJECTIVES: Labor pain is caused by several physiological changes and may cause psychological damage to the parturient and her relatives and, therefore, must be relieved. The objective of this study was to evaluate the knowledge, attitude, and practice of obstetricians concerning pharmacological methods of labor analgesia. METHODS: Cross-sectional study (38 obstetricians working at public maternity hospitals). A structured questionnaire was applied about knowledge, attitude and practice concerning systemic and regional pharmacological methods. The agreement magnitude was assessed by kappa coefficient. RESULTS: We observed adequate knowledge about the indications of all methods (31 to 86%), the contraindications of opioids (92%) and the adverse effects of non-opioid analgesics /antispasmodics on the fetus (76%). Concerning attitude, they agree that non-opioid analgesics/antispasmodics do not minimize labor pain (98%) but should be available at the maternity wards (89%) and that epidural analgesia is effective (100%) and should be available (94%). In practice, the indication of non-opioid analgesics/antispasmodic and epidural analgesia prevailed. In most of the requirements in each dimension (knowledge: K=-0.092 to 0.158; p=0.057 to 1.0 and attitude: K=-0.005 to 0.472; p=0.004 to 1.0), there was minimal agreement with practice, except for the non-opioid analgesics/antispasmodics (K=0.421, p=0.009), and epidural analgesia (K=0.472, p=0.004), with a moderate agreement. CONCLUSION: Knowledge was heterogeneous. The attitude was unanimous concerning the effectiveness and the need of having epidural available, and the ineffectiveness of non-opioid analgesics/ antispasmodics, and the practice of prescribing them. There was a minimal agreement between knowledge and practice, and between attitude and practice on most of the other requirements in each dimension.

RESUMO JUSTIFICATIVA E OBJETIVOS: A dor do parto é causada por diversas alterações fisiológicas e pode causar danos psicológicos à parturiente e seus familiares, portanto, deve ser aliviada. O objetivo deste estudo foi avaliar o conhecimento, atitude e prática de obstetras sobre métodos farmacológicos de analgesia de parto. MÉTODOS: Estudo transversal, com amostra de conveniência (38 obstetras que atuam em maternidades públicas). Foi aplicado um questionário estruturado sobre conhecimento, atitude e prática em relação a métodos farmacológicos sistêmicos e regionais. Magnitude de concordância avaliada pelo coeficiente Kappa. RESULTADOS: Observou-se conhecimento adequado nas indicações de todos os métodos (31 a 86%), contraindicações dos opioides (92%) e efeitos adversos de analgésicos simples/antiespasmódicos no feto (76%). Na atitude, concordam que os analgésicos simples/antiespasmódicos não funcionam no alívio da dor do parto (98%), mas devem estar disponíveis nas maternidades (89%), e que a analgesia peridural é eficaz (100%) e deve estar disponível (94%). Na prática, prevaleceu a indicação de analgésicos simples/antiespasmódicos e da analgesia peridural. Na maioria dos quesitos, em cada dimensão (conhecimento: K=-0,092 a 0,158; p=0,057 a 1,0 e atitude: K=-0,005 a 0,472; p=0,004 a 1,0), houve concordância mínima com a prática, excetuando analgésicos simples/antiespasmódicos (K=0,421; p=0,009) e analgesia peridural (K=0,472; p=0,004), com concordância moderada. CONCLUSÃO: O conhecimento foi heterogêneo. A atitude foi unânime quanto à eficácia e necessidade da analgesia peridural estar disponível, e ineficácia dos analgésicos simples e antiespasmódicos, e a prática de prescrevê-los. Houve concordância mínima entre o conhecimento e a prática, e entre a atitude e a prática, na maioria dos outros quesitos em cada uma das dimensões.

Apuntes sobre analgesia obstétrica (Analgesia obstétrica en la época victoriana) / Notes on obstetric analgesia (obstetric analgesia in the victorian age)

Este artículo hace mención a los prejuicios y conceptos equivocados en relación a la salud reproductiva y del conocimiento científico del embarazo y parto hasta principios del siglo XIX, de acuerdo a la sociedad patriarcal vigente hasta entonces. Desde este punto se hace referencia al desarrollo de la analgesia quirúrgica y particularmente a la del alivio del dolor del trabajo de parto, concepto impensable hasta entonces (la maldición de Eva). Se enfatiza el inmenso impacto mediático del hecho fortuito en relación al octavo parto de nadie menos que la Reina Victoria del Reino Unido, que recibió con éxito cloroformo en su octavo parto, lo que contribuyó a la amplia difusión de la práctica.

This article considers the prejudices and erroneous concepts in reproductive health and scientific knowledge of pregnancy and childbirth from the beginning of the nineteenth century. It refers to the development of surgical anesthesia and particularly pain relief in labor, a previously unknown concept (Eve´s curse). We emphasize the tremendous impact of the example of none other than Queen Victoria of the United Kingdom who helped spread the practice when she received chloroform when giving birth for the eighth time.

Horner's syndrome and paresthesia in the trigeminal nerve territory secondary to epidural analgesia for labor / Síndrome de Horner e parestesia do território do nervo trigêmeo secundário a analgesia peridural para trabalho de parto

Abstract Currently, epidural analgesia is a common procedure for labor analgesia. Although it is considered a safe technique, it is not without complications. Horner's syndrome and paresthesia within the trigeminal nerve distribution are rare complications of epidural analgesia. We report a case of a pregnant woman who developed Horner's syndrome and paresthesia within the distribution of the trigeminal nerve following epidural analgesia for the relief of labor pain.

Resumo A analgesia peridural é hoje em dia um procedimento comum para analgesia do trabalho de parto. Embora seja considerada uma técnica segura, não está isenta de complicações. A síndrome de Horner e a parestesia do território do nervo trigêmeo são complicações raras da analgesia peridural. Relatamos um caso de uma grávida que desenvolveu a síndrome de Horner e parestesia do território do nervo trigêmeo após analgesia peridural para o alívio da dor do trabalho de parto.

What does the Internet teach the obstetric patient about labor analgesia? / O que a internet ensina à paciente obstétrica sobre a analgesia de parto?

Abstract Background and objectives: It has been observed a general public increased search on the Internet for health information, including Anesthesiology. The objective of this study was to evaluate the information available to the lay person in Portuguese on the Internet about labor analgesia for the Brazilian population. Method: Using the term "labor anesthesia", the first 20 sites found on Google in November 2014 were evaluated by two resident physicians and classified as medical and non-medical. Legibility and Design - accessibility, reliability and navigability-were compared using Flesch Reading Ease Score (FRESH) and Minervation validation tool for healthcare websites (LIDA) tools. The websites' content was confronted with that of the medical literature. Results: Medical and non-medical websites were considered difficult to read according to FRESH. Regarding the design, there was no difference between groups regarding navigability, however, accessibility was considered superior in non-medical websites (p = 0.042); while reliability was higher in medical websites (p = 0.019). Conclusions: With the increased search for health information on the Internet and concern about improving the quality of childbirth care, it is fundamental that the content available to the layperson about labor analgesia is of quality and well understood. This study demonstrated that both medical and non-medical websites are difficult to read and that non-medical websites are more accessible while the medical ones are more accurate.

Resumo Justificativa e objetivos: Observa-se um crescimento da busca de informação no público geral sobre temas médicos na internet, inclusive em anestesiologia. O objetivo deste estudo foi avaliar a informação existente ao leigo na internet em língua portuguesa sobre analgesia de parto para a população brasileira. Método: Com o uso do termo "anestesia de parto", os 20 primeiros sites encontrados no Google em novembro de 2014 foram avaliados por dois médicos residentes e classificados como médicos e não médicos. Legibilidade e desenho - acessibilidade, confiabilidade e navegabilidade - foram comparados por meio das ferramentas Fresh (Flesch Reading Ease Score) e Lida (Minervation Validation Tool for Healthcare Websites). O conteúdo dos sites foi confrontado em relação à literatura médica. Resultados: Sites médicos e não médicos foram considerados de difícil leitura de acordo com o Fresh. Em relação ao desenho, não houve diferença entre os grupos quanto à navegabilidade. Entretanto, a acessibilidade foi considerada superior em sites não médicos (p= 0,042); enquanto que a confiabilidade foi maior em sites médicos (p= 0,019). Conclusões: Com aumento da busca de informações em saúde na internet e aumento da preocupação de melhorar a qualidade de assistência ao parto, é fundamental que o conteúdo disponível ao leigo sobre analgesia de parto seja de qualidade e compreendido. Este estudo demonstrou que tanto sites médicos como não médicos são de difícil leitura; e que os sites não médicos são mais acessíveis, enquanto os médicos são mais precisos.
