Emergency cesarean section in a parturient with ruptured sinus of valsalva under spinal anesthesia: A case report

@#Ruptured Sinus of Valsalva (RSOV) is a rarely encountered cardiac anomaly that can potentially lead to adverse clinical outcomes. RSOV increases the risk of morbidity during pregnancy due to the physiological changes associated with gestation, that can exacerbate the underlying cardiac pathology. We present the case of a 29-year-old female with an uncorrected RSOV who required an emergency cesarean section for abruptio placenta. The patient underwent the procedure under spinal anesthesia, with careful titration of norepinephrine infusion and close monitoring of hemodynamic parameters using an invasive intra-arterial line. Given the absence of established anesthetic protocols for parturients with RSOV undergoing cesarean delivery, a comprehensive understanding of the complex interaction between the hemodynamic effects of RSOV, pregnancy, and anesthesia is essential. This understanding enables the safe use of spinal anesthesia in urgent situations, leading to favorable patient outcomes.

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.

Rider sitting position widens lumbar intervertebral distance: a prospective observational study

Abstract Background: Reduced lumbar lordosis may make the process of identifying the intervertebral distance easier. The primary aim of this study was to measure the L3-L4 intervertebral space in the same patients undergoing spinal anesthesia in three different sitting positions, including the classic sitting position (CSP), hamstring stretch position (HSP) and rider sitting position (RSP). The secondary aim was to compare ultrasonographic measurements of the depth of the ligamentum flavum and intrathecal space in these three defined positions. Methods: This study is a single-blinded, prospective, randomized study. Ninety patients were included in final analysis. the patients were positioned on the operating table in three different positions to perform ultrasonographic measurements of the spinal canal. The intervertebral distance (IVD), the distance between the skin and the ligamentum flavum (DBSLF) and the intrathecal space (IS) were measured in the L3 -L4 intervertebral space in three different positions. Results: The RSP produced the largest mean distance between the spinous processes. The RSP yielded a significantly larger IVD than did the CSP (p < 0.001) and HSP (p < 0.001). The DBSP was larger in the CSP than in the HSP (p = 0.001). The DBSLF was significantly larger in the RSP than in the HSP (p = 0.009). Conclusions: Positioning the patient in the RSP significantly increased the intervertebral distance between L3 -L4 vertebrae compared to the CSP and HSP, suggesting easier performance of lumbar neuraxial block.

Effectiveness and safety of ultra-low-dose spinal anesthesia versus perineal blocks in hemorroidectomy and anal fistula surgery: a randomized controlled trial

Abstract Background: Ultra-low-dose Spinal Anesthesia (SA) is the practice of employing minimal doses of intrathecal agents so that only the roots that supply a specific area are anesthetized. The aim of this study was to compare the effectiveness and safety of ultra-low-dose spinal anesthesia with that of Perineal Blocks (PB). Methods: A two-arm, parallel, double-blind randomized controlled trial comparing two anesthetic techniques (SA and PB) for hemorrhoidectomy and anal fistula surgery was performed. The primary outcomes were postoperative pain, complementation and/or conversion of anesthesia, and hemodynamic changes. Results: Fifty-nine patients were included in the final analysis. The mean pain values were similar in the first 48 h in both groups (p > 0.05). The individuals allocated to the SA group did not need anesthetic complementation; however, those in the PB group required it considerably (SA group, 0% vs. PB group, 25%; p = 0.005). Hemodynamic changes were more pronounced after PB: during all surgical times, the PB group showed lower MAP values and higher HR values (p < 0.05). Postoperative urinary retention rates were similar between both groups (SA group 0% vs. PB group 3.1%, p = 0.354). Conclusion: SA and PB are similarly effective in pain control during the first 48 h after hemorrhoidec-tomy and anal fistula surgery. Although surgical time was shorter among patients in the PB group, the SA technique may be preferable as it avoids the need for additional anesthesia. Furthermore, the group that received perineal blocks was under sedation with a considerable dose of propofol.

Safety and effectiveness of adding fentanyl or sufentanil to spinal anesthesia: systematic review and meta-analysis of randomized controlled trials

Abstract Introduction Spinal infusions of either fentanyl or sufentanil have been reported in international reports, articles, and scientific events worldwide. This study aimed to determine whether intrathecal fentanyl or sufentanil offers safety in mortality and perioperative adverse events. Methods MEDLINE (via PubMed), EMBASE, CENTRAL (Cochrane library databases), gray literature, hand-searching, and clinicaltrials.gov were systematically searched. Randomized controlled trials with no language, data, or status restrictions were included, comparing the effectiveness and safety of adding spinal lipophilic opioid to local anesthetics (LAs). Data were pooled using the random-effects models or fixed-effect models based on heterogeneity. Results The initial search retrieved 4469 records; 3241 records were eligible, and 3152 articles were excluded after reading titles and abstracts, with a high agreement rate (98.6%). After reading the full texts, 76 articles remained. Spinal fentanyl and sufentanil significantly reduced postoperative pain and opioid consumption, increased analgesia and pruritus. Fentanyl, but not sufentanil, significantly reduced both postoperative nausea and vomiting, and postoperative shivering; compared to LAs alone. The analyzed studies did not report any case of in-hospital mortality related to spinal lipophilic opioids. The rate of respiratory depression was 0.7% and 0.8% when spinal fentanyl or sufentanil was added and when it was not, respectively. Episodes of respiratory depression were rare, uneventful, occurred intraoperatively, and were easily manageable. Conclusion There is moderate to high quality certainty that there is evidence regarding the safety and effectiveness of adding lipophilic opioids to LAs in spinal anesthesia.

Facteurs de morbidité du syndrome de mal-être post-rachianesthésie / Morbidity factors of post-spinal anesthesia disease syndrome

La pratique de la rachianesthésie est motivée par la qualité de l'analgésie post-opératoire qu'elle procure. Cependant, la rachianesthésie reste comme tout acte médical associée à certains accidents. Méthodes : C'est une étude prospective, descriptive et analytique qui s'est déroulée sur une période d'un (01) mois allant du 07 Mai 2022 au 07 Juin 2022 au CHU d'Angré. Résultats : la rachianesthésie a été réalisée dans 188 des cas, soit un taux de 60% de l'ensemble des interventions. Le sexe ratio était de 0,13 et l'âge moyen était de 33 ± 10 ans. L'antécédent le plus retrouvé était l'HTA. La bupivacaine était le seul anesthésique local utilisé avec comme adjuvant la morphine, le fentanyl ou l'association morphine -fentanyl. Les incidents peropératoires étaient dominés par les troubles hémodynamiques à type d'hypotension artérielle (98,7%) et de bradycardie. Les patients ayant présenté un syndrome de mal être post opératoire représentaient 70,8% de notre effectif. Le Syndrome de Mal Etre post opératoires était dominé par les nausées et vomissements suivis des prurits. Tous les patients ayant présenté un syndrome de mal être post rachianesthésie n'avaient pas bénéficié de prise en charge. La survenue du syndrome de mal être post rachianesthésie était statistiquement associé à la présence de la morphine comme adjuvant (p=0,016). Conclusion : La rachianesthésie est une remarquable technique d'anesthésie. Néanmoins la fréquence des évènements per et post opératoires survenant au décours de cette technique n'est pas négligeable, car ils sont la source d'inconforts notables

Rachianesthésie en ambulatoire au Centre Hospitalier Universitaire Andrainjato Fianarantsoa, Madagascar: tolérance et efficacité / Ambulatory spinal anaesthesia at the Andrainjato University Hospital of Fianarantsoa, Madagascar: tolerance and effectiveness

La rachianesthésie ambulatoire est une des méthodes d'anesthésies loco- régionales de plus en plus utilisées car permet une réhabilitation précoce. L'objectif de l'étude est d'évaluer la tolérance et l'efficacité de la rachianesthésie réalisée en ambulatoire. Méthodes : Il s'agit d'une étude rétrospective, analytique réalisée au Centre Hospitalier Universitaire Andrainjato Fianarantsoa pendant cinq ans (du mois de janvier 2016 au mois de décembre 2020). La tolérance de la rachianesthésie était évaluée par la fréquence et la gravité des incidents peropératoires et complications postopératoires. Son efficacité était estimée par le taux de sortie le jour de l'intervention et la ré-hospitalisation. Résultats : Soixante-quatre patients âgés de 44 [14-85] ans ont bénéficié d'une chirurgie viscérale, gynécologique, traumatologique ou vasculaire sous rachianesthésie. L'hypotension artérielle (n=04) et les nausées et vomissements peropératoires (n = 01) étaient les incidents retrouvés. Les complications postopératoires étaient la céphalée (n = 13), la douleur postopératoire d'intensité modérée à intense (n = 05) et les nausées et vomissements (n = 02). L'âge supérieur à 50 ans (p = 0,012) et une dose supérieure à 12 mg de bupivacaïne (p = 0,011) étaient corrélés à l'hypotension artérielle peropératoire. Le genre féminin (p = 0,004) et l'utilisation de la bupivacaïne hyperbare (p = 0,027) étaient associés aux complications postopératoires. Tous ces patients étaient sortis le jour même de l'intervention sans ré-hospitalisation. Conclusion : La rachianesthésie ambulatoire connaît actuellement un grand essor dans la pratique anesthésique. La prévention de certaines complications devrait être systématique afin d'optimiser sa tolérance et son efficacité

Gastrosquisis: Experiencia del Hospital Carlos van Buren en el manejo anestésico del Símil-EXIT. Un estudio de cohorte retrospectiva / EXITE-like procedure to treat gastroschisis, is anesthesia an issue? A retrospective cohort study

OBJECTIVES: To describe the anesthetic techinque used during EXIT-like procedures and assess its effects in the overall success rate of the intervention. METHODOLOGY: Retrospective cohort study of 32 mother-newborn pairs with an antenatal diagnosis of gastroschisis in whom a primary closure was planned using the EXIT-like procedure. RESULTS: In 26 (81.3%, 95%CI 63.5-92.8%) cases a successful closure of the abdominal defect was achieved. A slightly reduced success rate was found amongst patients receiving spinal anesthesia (71.4%) when compared with general (80.0%) and mixed techniques (86.7%), which did not reach statistical significance. CONCLUSIONS: No association was found between anesthesia technique and EXIT-like procedure success rates. Futher randomised studies are needed to confirm these findings.

OBJETIVOS: Describir la técnica anestésica actual utilizada para el cierre primario de la gastrosquisis mediante técnica Simil-EXIT y evaluar si esta condiciona a la tasa de éxito del procedimiento. METODOLOGÍA: Análisis de una cohorte de 32 binomios madre-recién nacidos con diagnóstico antenatal de gastrosquisis en los que se planificó cierre primario mediante técnica Simil-EXIT entre los años 2010 y 2021 en el Hospital Carlos Van Buren. RESULTADOS: Se reportó una tasa de éxito del procedimiento quirúrgico en 26 participantes (81,3%, IC 63,5%-92,8%), sin encontrar una diferencia estadística en relación con la técnica anestésica utilizada (espinal, general o general-espinal), aunque se encontró una menor tasa de éxito con la técnica espinal (71,4%, 80%, 86,7% respectivamente). CONCLUSIONES: No se observó diferencia en la tasa de éxito de del procedimiento Simil-EXIT y su relación con la técnica anestésica utilizada. Sin embargo, no se puede descartar la superioridad de la técnica general o general-espinal con los datos obtenidos siendo necesario realizar un estudio clínico aleatorizado con un mayor número de participantes.

Preoperative assessment of inferior vena cava collapsibility index by ultrasound is not a reliable predictor of post-spinal anesthesia hypotension

Abstract Background Post-spinal anesthesia hypotension is of common occurrence, and it hampers tissue perfusion. Several preoperative factors determine patient susceptibility to hypotension. This study aimed to assess the effectiveness of the Inferior Vena Cava Collapsibility Index (IVCCI) for predicting intraoperative hypotension. Methods One hundred twenty-nine adult patients who were scheduled for elective surgical procedures after administration of spinal (intrathecal) anesthesia were included in the study. Ultrasound evaluation of the Inferior Vena Cava (IVC) was done in the preoperative area, and the patients were shifted to the Operating Room (OR) for spinal anesthesia. An independent observer recorded the change in blood pressure after spinal anesthesia inside the OR. Results Twenty-five patients developed hypotension (19.37%). Baseline systolic blood pressure and mean blood pressures were statistically higher in those patients who developed hypotension (p= 0.001). The logistic regression analysis for IVCCI and the incidence of hypotension showed r2 of 0.025. Receiver Operating Characteristic (ROC) curve analysis demonstrated the Area Under the Curve (AUC) of 0.467 (95% Confidence Interval, 0.338 to 0.597; p= 0.615). Conclusions Preoperative evaluation of IVCCI is not a good predictor for the occurrence of hypotension after spinal anesthesia.

Anestesia raquídea con bupivacaína isobárica en cesáreas / Spinal anesthesia with isobaric bupivacaine in cesarean sections

En la anestesia para las cesáreas, la anestesia raquídea con bupivacaína hiperbárica constituye la elección habitual en nuestro medio. Existen dos formas de bupivacaína disponibles, la isobárica (BI) y la hiperbárica (BH). La utilización de la BI es poco frecuente por lo que es relevante conocer la experiencia en su utilización para las anestesias de las cirugías obstétricas. El objetivo del estudio fue caracterizar la utilización de BI en las anestesias raquídeas para cesáreas. Se realizó un estudio observacional, descriptivo, de corte transversal en 23 pacientes que recibieron anestesia espinal con BI. La edad promedio fue de 28  5 años, la dosis promedio de BI utilizada de 9,4 mg. La latencia promedio fue 90 segundos y el tiempo para la instauración una anestesia adecuada fue en promedio 4,9 minutos. En el 82,6% el nivel anestésico alcanzó el dermatoma T4. En el 21,7% fue necesario administrar efedrina para aumentar la presión arterial. En el 52,1% se presentaron efectos adversos menores. A las 24 horas, el dolor fue nulo en 56,5% y leve en 43,5% de los casos. En conclusión, se encontró que las pacientes alcanzaron un nivel sensitivo adecuado en poco tiempo, con una dosis promedio de BI de 9 mg. Pocos pacientes requirieron la administración de un vasopresor para aumentar la presión arterial. Los efectos adversos fueron menores en casi la mitad de los pacientes. En el post operatorio la mayoría de las pacientes no presentaron dolor

In anesthesia for caesarean sections, spinal anesthesia with hyperbaric bupivacaine is the usual choice in our setting. There are two forms of bupivacaine available, isobaric (BI) and hyperbaric (BH). The use of BI is infrequent, so it is relevant to know the experience in its use for anesthesia in obstetric surgeries. The objective of the study was to characterize the use of BI in spinal anesthesia for cesarean sections. An observational, descriptive, cross-sectional study was carried out in 23 patients who received spinal anesthesia with BI. The average age was 28  5 years, the average dose of BI used was 9.4 mg. The average latency was 90 seconds and the time for establishment of adequate anesthesia was on average 4.9 minutes. In 82.6% of the cases, the anesthetic level reached dermatome T4. In 21.7% it was necessary to administer ephedrine to increase blood pressure. Minor adverse effects occurred in 52.1%. At 24 hours, the pain was null in 56.5% and mild in 43.5% of cases. In conclusion, it was found that the patients reached an adequate sensory level in a short time, with an average dose of BI of 9 mg. Few patients required administration of a vasopressor to increase blood pressure. Adverse effects were minor in almost half of the patients. In the postoperative period, most of the patients did not present pain

Sección de catéter epidural durante técnica anestésica espinal epidural combinada / Epidural catheter section during combined epidural spinal anesthetic technique

Estos son empleados con seguridad desde hace varias décadas; sin embargo, algunas complicaciones suelen presentarse. Una poco frecuente es su sección, la cual de no ser manejada adecuadamente genera importante morbilidad. Se presenta el caso de una paciente que recibe anestesia espinal epidural combinada. La técnica empleada, tanto para la colocación del catéter como para su retiro, aparentemente, fue correcta; sin embargo, este sufre una sección al retirarlo. En las imágenes posteriores se evidenciaría que el catéter se situó, accidentalmente, en el espacio paravertebral. Se teoriza un mecanismo de ruptura aun no descrito en la bibliografía. Se publica con el objetivo de mostrar la necesidad de la individualización en el manejo de este accidente, ya sea expectante o quirúrgico según las condiciones clínicas de cada paciente(AU)

The use of epidural catheters is a fundamental pillar of anesthesia. These have been safely employed for several decades; however, some complications usually occur. A rare one is its section, which if not properly managed generates significant morbidity. It is presented the case of a patient receiving combined epidural spinal anesthesia. The technique used, both for the placement of the catheter and for its removal, was apparently correct; however, it suffered a section when removed. In the subsequent images it was evident that the catheter was accidentally placed in the paravertebral space. A mechanism of rupture not yet described in the literature is theorized. It is published with the aim of showing the need for individualization in the management of this accident, whether expectant or surgical according to the clinical conditions of each patient(AU)

Prophylactic paracetamol for intraoperative shivering prevention for patients undergoing gynecological procedures under spinal anesthesia: A randomized clinical trial

Introduction@#Shivering is defined as an involuntary, repetitive activity of skeletal muscles. Mechanisms of shivering for patients undergoing surgical operation include intraoperative heat loss, increase sympathetic tone, pain, and systemic release of pyrogens. Regional anesthesia, particularly spinal anesthesia causes redistribution of core heat to the peripheral tissues this in turn predisposes patient to shivering and hypothermia. The median incidence of shivering related to regional anesthesia observed in a review of 21 studies is 55%. Paracetamol is one of the most commonly used analgesic and antipyretic drugs around the world, available without a prescription, it has analgesic and antipyretic property similar to NSAIDs it also affects core body temperature through the hypothalamus. Though different modalities have been established for shivering prevention, the search for a cost-effective drug with lesser side effects and improvement of patient satisfaction still continues. @*Objective@#The aim of this study was to evaluate the effect of prophylactic dose of Paracetamol on postanesthesia shivering on patients undergoing, gynecological procedures under spinal anesthesia as compared to patients not given Paracetamol.@*Methodology@#This is a Double blind, Randomized, Placebo Controlled conducted in patients scheduled for benign gynecological procedures such as Hysterectomy with or without adnexectomy. Using simple random sampling through fishbowl method and a sample size of 42, all patients who consented to participate in the study was randomly assigned to receive Paracetamol 900 mg IV or Placebo 0.9% Saline intravenously 30 minutes prior to induction of spinal anesthesia. Incidence and severity of Shivering was documented using shivering five point scale outlined by Crossley and Mahajan, while patient satisfaction was also evaluated using the Likert Scale, possible side effects was also assessed.

Medicina perioperatoria para operación cesárea / Perioperative medicine in cesarian section

INTRODUCTION: Caesarean section is the most frequent surgery worldwide, the ideal rate for this procedure should be 19%, currently it's on the rise worldwide. To reduce the morbidity and mortality associated with anesthetic-surgical procedures in pregnant patients, correct perioperative assessment is necessary, capable of recognizing the risks to which these patients are exposed and being able to create strategies to reduce them. OBJECTIVE: The patients present risks inherent of pregnancy condition. The following work is carried out with the aim of prioritizing the preoperative assessment for the patient undergoing cesarean delivery to reduce maternal-fetal morbidity and mortality associated with anesthetic-surgical procedures. METHODOLOGY: A non-systematized bibliographic search was carried out in Pubmed, Medline, Portal Timbo, Scielo databases to evaluate the perioperative management of cesarean section. The reference keywords used were "cesarean section", "anesthesia", "perioperative care", "maternal mortality". RESULTS: A review of the perioperative management for cesarean section was carried out, emphasizing the recognition of risks to which the patients are exposed and strategies to reduce them are proposed with the aim of reducing the morbidity and mortality of the patients. CONCLUSIONS: Patients undergoing cesarean delivery have a high risk of complications, the most common are presented in the manipulation of the airway, aspiration of gastric content, infections, bleeding, and thrombosis, recognizing these risks and acting on each one of them can reduce the morbidity and mortality of patients.

INTRODUCCIÓN: La cesárea es la cirugía más frecuente a nivel mundial, actualmente la misma viene en ascenso.

Se realiza el siguiente trabajo con el objetivo de priorizar la valoración preoperatoria para la paciente sometida a parto por cesárea con la finalidad de disminuir la morbimortalidad materno-fetal asociada a procedimientos anestésicoquirúrgicos. METODOLOGÍA: Se realizó una búsqueda bibliográfica no sistematizada en bases de datos Pubmed, Medline, Portal Timbo, Scielo, para evaluar el manejo perioperatorio de la cesárea. Se utilizaron como palabras clave de referencia "cesarean section", "anesthesia", "perioperative care", "maternal mortality". RESULTADOS: Se realizó una revisión del manejo perioperatorio para la cesárea, se realiza énfasis en el reconocimiento de riesgos a los cuales las pacientes están expuestas y se plantean estrategias de disminución de estos con el objetivo de reducir la morbimortalidad de las pacientes. CONCLUSIONES: Las pacientes sometidas a parto por cesárea presentan alto riesgo de complicaciones, las más comunes se presentan en la manipulación de la vía aérea, aspiración de contenido gástrico, infecciones, sangrado y trombosis, reconociendo dichos riesgos y actuando sobre cada uno de ellos se puede disminuir la morbimortalidad de las pacientes.

Mielitis transversa aguda asociada a anestesia espinal: Caso clínico / Acute transverse myelitis related to spinal anesthesia: Case report

Neurological impairment after neuraxial anesthesia is very uncommon, but with possible severe consequences. We report the case of a 30-year-old patient scheduled for elective surgery under spinal anesthesia who presented pain during the procedure and neurological impairment in the lower extremities during the postoperative period. The specialized analysis of the case and the paitient's evolution showed that the cause was an acute transverse myelitis. The relationship between this entity and anesthesia is controversial; however, it must be considered in patients undergoing neuroaxial anesthesia who evolve with postoperative neurological impairment and pain in their lower extremities, even though there are no warning symptoms during the procedure. The objective of this report is to alert about the importance of the observation in patients who present pain during neuraxial anesthesia and the prompt evaluation of those who evolve with pain or neurological impairment after the procedure.

El déficit neurológico después de anestesia neuroaxial es de ocurrencia muy infrecuente, pero de posibles consecuencias severas. Reportamos el caso de un paciente de 30 años programado para cirugía electiva bajo anestesia espinal que presentó dolor durante el procedimiento y déficit neurológico de extremidades inferiores en el posoperatorio inmediato. El análisis especializado del caso y su evolución clínica mostraron que se trataba de una mielitis transversa aguda. La relación entre esta entidad y anestesia es controversial; sin embargo, debe ser considerada en los diagnósticos diferenciales en pacientes sometidos a anestesia neuroaxial que evolucionen con dolor y déficit neurológico posoperatorio en sus extremidades inferiores, a pesar de que no haya síntomas de alerta durante el procedimiento. El objetivo de este reporte es alertar acerca de la importancia de la observación de pacientes que presenten dolor durante la anestesia neuroaxial y el estudio inmediato de aquellos que evolucionen con dolor o déficit neurológico después del procedimiento.

Anestesia neuroaxial y sedación para cierre quirúrgico de comunicación interatrial (CIA) / Atrial septal defect surgical repair under Neuroaxial anesthesia and sedation: case report

We present the case report of one of the co-authors for the closure of her atrial septal defect under neuraxial anesthesia. The influence of the Cardiovascular Anesthesiologist on the response to perioperative stress in the context of cardiac surgery with the choice and application of the best anesthetic technique adjusted to a high-risk patient, has a positive impact on the main objectives of high-value care in the critical area of medicine and in the immediate postoperative evolution after a heart surgery. The safety of neuraxial anesthesia in cardiac surgery is a subject in wide debate in Mexico, even in hospitals with high volume of cardiac surgery it is a controversial subject, we present the first clinical case in Mexico of a 21-year-old female patient under- going closure of Atrial septal defect (ASD) via median sternotomy with extracorporeal circulation under neuraxial anesthesia and sedoanalgesia without orotracheal intubation.

Presentamos el reporte de caso de una de las coautoras para el cierre de su comunicación interatrial bajo anestesia neuroaxial. La influencia del Anestesiologo Cardiovascular en la respuesta al estres perioperatorio en el contexto de cirugía cardíaca con la elección y aplicación de la mejor tecnica anestesica ajustada a un paciente de alto riesgo, tiene un impacto positivo en los principales obejtivos del cuidado de alto valor en el área de la medicina critica y en la evolución posoperatoria inmediata tras una cirugía caridaca. La seguridad de la anestesia neuroaxial en cirugía cardíaca es un tema en amplio debate en México, aun en hospitales con alto volumen de cirugía cardíaca es un tema controversial. Presentamos el primer caso clínico en México de una paciente femenino de 21 años sometida a cierre de comunicación interauricular (CIA) vía esternotomia media con circulación extracorporea bajo anestesia neuroaxial y sedoanalgesia sin intubación orotraqueal.

Seguridad de la anestesia neuroaxial en mujeres con embarazo gemelar y síndrome de transfusión feto-fetal, sometidas a fotocoagulación láser. Estudio de cohorte retrospectiva / Safety of neuraxial anesthesia in patients twin pregnancy and twin-to-twin transfusion syndrome taken to laser photocoagulation. Retrospective cohort study

Objetivo: describir las características clínicas y la frecuencia de complicaciones maternas, fetales y neonatales, según técnica de anestesia neuroaxial (AN) en mujeres con síndrome de transfusión feto-fetal (STFF) tratadas con fotocoagulación láser (FL). Materiales y métodos: estudio de cohorte retrospectiva descriptivo. Se incluyeron gestantes con STFF tratadas con FL y AN en la Fundación Valle del Lili, Cali (Colombia) entre 2013-2017. Se excluyeron pacientes con STFF estadio-V de Quintero. Se usó estadística descriptiva. El protocolo fue aprobado por el Comité de Ética de la institución. Resultados: 32 participantes cumplieron con los criterios de inclusión y de exclusión. La población estuvo constituida por mujeres jóvenes, multíparas. En el 87,5% de los casos se realizó intervención de urgencia. El 43,7% presentaba el estadio-III de Quintero y en el 56,2 % de las gestantes se utilizó anestesia epidural. Las variables hemodinámicas maternas exhibieron un comportamiento similar, acorde al momento de la cirugía y la técnica neuoraxial implementada. El 65,6 % de las gestantes presentó hipotensión sostenida y el 9,3 % desarrolló edema pulmonar. El 65,6 % de las pacientes experimentó parto pretérmino y el 18,7 % ruptura prematura de membranas. Se registraron 14 muertes fetales y cinco neonatales. No se registraron casos de mortalidad materna. Conclusiones: en pacientes con STFF que requieren FL, el uso de la anestesia epidural, espinal o combinada probablemente se asocia con un comportamiento similar al de las variables hemodinámicas maternas, durante los momentos de la cirugía. Los profesionales que brindan atención a estas gestantes deben estar alerta ante la frecuente aparición de complicaciones maternas, fetales y neonatales. Se requieren estudios prospectivos que evalúen la seguridad y la efectividad de las diferentes técnicas de anestesia neuroaxial en pacientes con STFF.

Objective: To describe the clinical characteristics and the frequency of maternal, fetal and neonatal complications in accordance with the neuraxial anesthesia (NA) technique in women with twin-to- twin transfusion syndrome (TTTS) treated with laser photocoagulation. Materials and Methods: Descriptive retrospective cohort study of pregnant patients with TTTS treated with laser photocoagulation under NA at Fundación Valle del Lili, Cali (Colombia), between 2013-2017. Patients with Quintero stage VTTTS were excluded. The protocol was approved by the institutional ethics committee. Results: Of the participants, 32 met the inclusion and exclusion criteria. The study population consisted of young, multiparous women. Urgent interventions were performed in 87.5% of cases; 43.7% were Quintero stage III and epidural anesthesia was used in 56.2% of the women. Maternal hemodynamic variables were similar, in accordance with the timing of surgery and the neuraxial technique used. Sustained hypotension occurred in 65.6% of the pregnant women and 9.3% developed pulmonary edema. Pre-term delivery occurred in 65.6% of the patients and 18.7% had premature rupture of membranes. There were 14 fetal demises and five neonatal deaths. There were no cases of maternal mortality. Conclusions: In patients with TTTS requiring laser photocoagulation, the use of epidural, spinal or combined anesthesia is likely associated with similar maternal hemodynamic variables at the time of surgery. Practitioners providing care to these pregnant women must be aware of the frequent occurrence of maternal, fetal and neonatal complications. Prospective studies to assess the safety and effectiveness of the different neuraxial anesthesia techniques in patients with TTTS are required.

Juan Evangelista Manrique, the true pioneer of spinal anesthesia in Colombia / El verdadero pionero de la raquianestesia en Colombia: Juan Evangelista Manrique

Abstract Several findings paved the way to the use of the spinal approach for anesthesia. Information about the originators and dates of their discoveries is controversial. According to personal communications, doctors Juan Bautista Montoya y Flórez, in Medellín, and Lisandro Leyva, in Bogotá, in 1904 and 1905 respectively, would appear to be the pioneers of spinal anesthesia in Colombia. Pioneering cases of this procedure carried out in 1901 by doctor Juan Evangelista Manrique and which continued to be performed by his colleagues and assistants of the medical community at the time are documented in the Corporis Fabrica dissertation collection of the National University of Colombia.

Resumen Son varios los hallazgos que contribuyeron al abordaje de la columna vertebral como vía para la administración de anestesia. Los autores y las fechas de tales descubrimientos han sido controvertidos. En Colombia, según fuentes orales, los doctores Juan Bautista Montoya y Flórez, en Medellín, y Lisandro Leyva, en Bogotá, en 1904 y 1905 respectivamente, serían los pioneros de la anestesia raquídea en Colombia. En las tesis de la Facultad de Medicina de la Universidad Nacional, Colección Corporis Fabrica, se documentan los casos pioneros de este procedimiento realizados en 1901, por el doctor Juan Evangelista Manrique y continuados enseguida por sus colegas y ayudantes de la comunidad médica de ese entonces.

Trombosis venosa profunda y trombofilia congénita / Deep-vein thrombosis and congenital thrombophilia

Introducción: La trombofilia es un desorden de la hemostasia congénito o adquirido que predispone al desarrollo de trombosis. Las trombofilias congénitas más frecuentes son las deficiencias de antitrombina III, proteína C y proteína S, el factor V Leiden, la mutación del gen de la protrombina (G20210A) y las mutaciones de la enzima metilentetrahidrofolato reductasa (MTHFR). Objetivo: Describir el manejo anestésico en un paciente portador de trombofilia congénita. Presentación del caso: Se reporta un paciente de 19 años de edad con antecedentes de historia familiar y personal de trombosis venosa profunda, tratamiento con doble antiagregación plaquetaria y asociación de tres mutaciones para trombofilia congénita, G20210A, A1298C MTHFR y C677T MTHFR que recibe anestesia espinal para una herniorrafia inguinal. Se mantiene tratamiento con aspirina, se suspende clopidogrel 7 días antes de la cirugía y durante ese tiempo se administra fraxiparina 0.6 Uds. subcutánea diarias hasta 12 h antes de la cirugía, se utiliza medias elásticas, deambulación precoz y reinicio de clopidogrel 24 h después de la cirugía, con evolución satisfactoria. Conclusiones: La tromboprofilaxis en pacientes portadores de trombofilia congénita es mandatoria, por eso resulta determinante la utilización de heparina de bajo peso molecular junto al resto de las medidas de prevención de la trombosis venosa profunda(AU)

Introduction: Thrombophilia is a congenital or acquired hemostasis disorder that predisposes to thrombosis development. The commonest congenital thrombophilias are deficiencies of antithrombin III, protein C and protein S, factor V Leiden, prothrombin gene mutation (G20210A), and methylenetetrahydrofolate reductase (MTHFR) mutations. Objective: To describe the anesthetic management in a patient with congenital thrombophilia. Case presentation: The case is reported of a 19-year-old patient with a family and personal history of deep-vein thrombosis, treatment with double antiplatelet therapy and association of three mutations for congenital thrombophilia (G20210A, A1298C MTHFR and C677T MTHFR), who receives spinal anesthesia for an inguinal herniorrhaphy. Aspirin treatment is maintained. Clopidogrel is suspended seven days before surgery. During this time, fraxiparin is administered subcutaneously in 0.6-mL units daily, up to twelve hours before surgery. Elastic stockings are used, early ambulation is allowed, and clopidogrel is restarted 24 hours after surgery, with satisfactory evolution. Conclusions: Thromboprophylaxis in patients with congenital thrombophilia is mandatory, a reason why the use of low-molecular-weight heparin, together with the rest of the prevention measures against deep-vein thrombosis, is decisive(AU)
