Use of cannabinoids for acute postoperative pain.

Doubts about the efficacy of medicinal cannabis in the treatment of acute postoperative pain are well justified, at least in light of the information gathered from Google Scholar, Clinical Trials, PubMed, and Cochrane databases.The conflation of cannabis and cannabinoids engenders not only normative but also medical implications. Despite cannabinoids having evinced their efficacy in the treatment of various pathologies, they have yet to demonstrate such in the context of acute postoperative pain. The burgeoning corpus of research on this subject does instill a modicum of hope in this regard; nevertheless, the manifold methodological approaches employed obfuscate the prospect of reaching unequivocal conclusions.Given the current status of this matter, this article abstains from making a definitive pronouncement either in favor of or against the role of pharmaceuticals incorporating cannabinoid compounds in the management of acute postoperative pain.

Strategy for the management of acute postoperative pain in day surgery centres in Spain. DUCMA 2.0. project.

INTRODUCTION: Adequate treatment of acute postoperative pain is one of the quality requirements in ambulatory surgery and its suboptimal management is associated with delayed discharge, unplanned admissions and late admissions after home discharge. The aim of the present study was to learn about the organizational strategy for the management of postoperative pain in ambulatory surgery units (ASU) in Spain. METHODS: A cross-sectional, multicenter study was carried out based on an electronic survey on aspects related to the management of acute postoperative pain in different ASUs in our country. RESULTS: We recruited 133 ASUs of which 85 responded to the questions on the management of postoperative pain. Of the ASUs that responded, 80% had specific protocols for pain management and 37.6% provided preoperative information on the analgesic plan. The assessment of postoperative pain is carried out in 88.2% of the ASUs in the facility and only 56.5% at home. All ASUs use multimodal analgesia protocols; however, 68.2% report the use of opioids for the treatment of moderate to severe pain. Home invasive analgesia strategies are minimally used by the surveyed ASUs. CONCLUSIONS: The DUCMA study highlights that the practice of pain treatment in day surgery remains a challenge in our country and is not always in agreement with national guidelines. The results suggest the need to establish strategies to improve clinical practice and homogenize pain management in ambulatory surgery.

The management of paediatric acute pain in Spain in 2021: Results of a national survey among paediatric anaesthesiologists.

OBJECTIVE: To improve knowledge about routine clinical practice in the management of paediatric acute pain in Spain. METHODS: A telematic survey was conducted via the Internet on a representative sample of healthcare professionals involved in the management of paediatric acute pain (specifically anaesthesiologists) in Spain. The survey included 28 questions about their usual clinical practice in the assessment and treatment of acute pain, and also training and organisational aspects in paediatric acute pain. RESULTS: The survey was completed during March 2021 by 150 specialists in anaesthesiology. The respondents widely experienced in the management of acute paediatric pain (mean years of experience: 14.3: SD: 7.8), essentially in acute postoperative pain (97% of cases). Although 80% routinely used validated paediatric acute pain assessment scales, only 2.6% used specific scales adapted for patients with cognitive impairment. Most of the respondents routinely used analgesic drugs such as paracetamol (99%) or metamizole (92%), but only 84% complemented these drugs with a loco-regional blocking technique or other non-steroidal anti-inflammatory drugs (62%). Furthermore, only 62.7% acknowledged having received specific training in paediatric acute pain, only 45% followed hospital institutional protocols, and a scant 28% did so through paediatric pain units. CONCLUSIONS: The survey identified important points for improvement in the training and organisation of acute pain management in Spanish paediatric patients.

Ultrasound-guided sciatic popliteal block performed at the Emergency Department in a patient with a scorpion bite and severe pain.

We report the case of a paediatric patient who presented at the Emergency Department with severe pain in the right lower extremity caused by a scorpion sting. Analgesics were ineffective, so we decided to perform an ultrasound-guided popliteal block, which provided complete analgesia and allowed the patient to be followed up in the outpatient department, with no adverse effects. The sting of the species of scorpion found in Spain is not dangerous to human life; however, it causes self-limiting localised pain that lasts for 24-48h, and can be severe. The first-line treatment is effective analgesia. Regional anaesthesia techniques are useful in the control of acute pain, and are an example of effective collaboration between the Anaesthesiology and Emergency services.

Management of acute postoperative pain: Conditions to guarantee the safety and effectiveness of analgesic treatments.

The evidence on postoperative pain management is of low or insufficient quality. The SEDAR Acute Pain Working Group has prepared this guideline-document to apply the best available scientific evidence to clinical practice, individualizing it based on factors specific to the patient and the procedure, and encompassing different organizational options, attempting to individualize it based on specific factors of the patient and the procedure, and encompassing the different organizational options for pain control. The document updates concepts and minimum requirements necessary for optimal postoperative analgesia, a multidisciplinary approach and the management of Acute Postoperative Pain. Strategic lines and different management models are defined. A general perioperative action plan is established based on collaboration with the surgical departments involved, on the joint review of the evidence and on preparation of protocols by the procedure. Finally, a follow-up plan and a series of minimum indicators necessary for quality control of postoperative pain are presented.

Effectiveness of acute post-operative pain management by the acute pain service.

BACKGROUND: Analgesia by specialists with formal training in pain management could be more effective, to find out, the results of a team of an acute pain service will be determined. METHODS: Retrospective study (n = 108) of post-operative (POP) analgesia; two evaluations were taken: before starting analgesics in the immediate POP period and the second at 24 h. A multivariate analysis was performed to establish independent risk factors associated with the effectiveness of the treatment. RESULTS: The effectiveness was 81.48% at 24 h. The risk factors associated with poor management effectiveness were: a comorbidity, prevalence ratio (PR) = 1.22; fibromyalgia (PR = 8.47), and cancer (PR = 2.47). The duration of surgery was associated with poor control PR = 1.10 for each hour elapsed. Protective factors for poor pain control: administration of non-steroidal anti-inflammatory drugs during the POP period (PR = 0.11) and use of analgesia controlled by the patient (PR = 0.29). CONCLUSION: POP pain relief is multifactorial; the participation of specialists was very effective. Identification of risk factors led to closer follow-up.

OBJETIVO: La analgesia por especialistas con entrenamiento formal en manejo del dolor podría ser más efectiva, para averiguarlo se determinarán los resultados de un servicio de dolor agudo. MATERIAL Y MÉTODOS: Estudio retrospectivo (n = 108) de analgesia postoperatoria; se tomaron dos evaluaciones: antes de iniciar analgésicos en el postoperatorio inmediato y la segunda a las 24 horas. Se realizó un análisis multivariado para establecer los factores de riesgo independientes asociados con la efectividad del tratamiento. RESULTADOS: La disminución promedio fue 51,75% en el primer día postoperatorio. La efectividad fue del 81,48% a las 24 horas. Los factores de riesgo asociados con la mala efectividad del manejo fueron: una comorbilidad, razón de prevalencia (RP) = 1,22; fibromialgia (RP = 8,47) y cáncer (RP = 2,47). La duración de la cirugía se asoció con un mal control PR = 1,10 por cada hora transcurrida. Factores protectores para el mal control del dolor: administración de antiinflamatorios no esteroideos durante el postoperatorio (RP = 0,11) y uso de analgesia controlada por el paciente (RP = 0,29). CONCLUSIÓN: el alivio del dolor posoperatorio es multifactorial, la participación de especialistas fue muy eficaz. La identificación de los factores de riesgo condujo a un seguimiento más estrecho.

Ultrasound-guided sub-multifidus block for postoperative pain after lumbar spine surgery - a prospective case series.

We describe this series of 15 cases who were scheduled for single level lumbar spine decompression with instrumentation. Here we describe ultrasound (US) guided sub-multifidus block (SMFB). Injections of local anesthetic deep to the multifidus muscle provided reliable block of dorsal rami of spinal nerves at multiple levels in this series. With US the multifidus muscle can be identified both in axial and parasagittal planes. Needle tip is easily visualized beneath the multifidus and medial to transverse process. A good quality analgesia was documented by pain scores. There were no adverse events. This block needs to be compared with routine multimodal analgesia or with the recently describe thoracolumbar interfascial plane block to compare safety and analgesic efficacy.

BRILMA block for costal cartilage excision: Case report. / Bloqueo BRILMA para extirpación de cartílago costal: caso clínico.

The block of the lateral branches of the intercostal nerves in the middle axillary line (BRILMA) is an interfascial ultrasound-guided block for analgesia in thoracic wall and upper abdominal surgery, presenting as an adequate alternative to neuraxial techniques. We present the case of a 49-year-old female scheduled for idiopathic subglottic stenosis repair with a costal cartilage graft from the 10th rib and tracheotomy. At the end of the surgery, unilateral ultrasound-guided BRILMA block with 20ml of ropivacaine 0.2% was performed at the level of the 6th rib, uneventfully. Postoperatively, the patient referred a maximum level of pain of 3/10. There was no opioid consumption after the 2nd postoperative day, although a subcostal incision may produce considerable pain. BRILMA is a superficial block, easily reproducible in most patients. It diminishes the number of punctures needed in the thoracic wall, as well as the risk for pneumothorax and local anesthetic toxicity.

Painapple®. Validation and evaluation of an electronic application for the management of acute pain in pediatric patients. / PainAPPle. Validación y evaluación de una aplicación electrónica para el manejo del dolor agudo en pacientes pediátricos.

INTRODUCTION: The digital version of the assessment scales recommended for the pediatric patient could contribute to its improvement and to implement the quality indicators described for the management of acute pain. MATERIAL AND METHODS: Psychometric validation (validity and reliability) of pain assessment and treatment side effects scales incorporated in the electronic application PainAPPle. For this, both formats (paper and electronic) of all the scales were applied in two measurements with 30minutes of difference in 44 patients from 4 to 18years of the Acute Pain Unit in the immediate postoperative period. In addition, the data collected by PainAPPle was evaluated by retrospectively applying the quality indicators described for the management of acute postoperative pain. RESULTS: Reliability was studied analyzing the high correlation (Spearman greater than 0.5, P<.001) that we obtained for the values of each scale in two moments with 30minutes of difference, in the same patients. For validity, the high correlation (Spearman greater than 0.5, P<.001) between the values of the paper scales (gold rule) and PainAPPle at both minute 0 and 30 was analyzed. Concordance obtained taking into account the cut-off point of the scales that would force a treatment were also statistically significant (P<.005). CONCLUSIONS: PainAPPle is a validated instrument for the management of acute pain in pediatric patients. The collected data allow to apply the quality indicators described for the management of acute postoperative pain.

Bloqueo del músculo erector de la espina como rescate analgésico para control de dolor agudo postoperatorio en fractura de escápula: reporte de caso / Erector spinae plane block as an analgesic rescue to acute control postoperative pain in scapula fracture: case report

Resumen: Introducción: el bloqueo en el plano del músculo erector de la espina (ESPB, por sus siglas en inglés) es un procedimiento seguro, en teoría menos exigente que las técnicas convencionales de anestesia regional torácica. Se utiliza para el tratamiento del dolor agudo y crónico. En la revisión de la literatura, no se encontraron informes de su uso como una técnica única en el dolor agudo de fractura de escápula. Presentación de caso: se reporta un caso clínico de ESPB como técnica experimental para el control del dolor postoperatorio agudo en fracturas de la escápula con aplicación a nivel T2. Se llevó a cabo postoperatorio con disminución de dolor después de 10 minutos de realizado, con una calificación de cero en la escala análoga del dolor. En este caso el ESPB fue realizado en el postoperatorio inmediato, con lo que se logró una disminución total del dolor a los 10 minutos, con posterior control de dolor a las 36 horas. Conclusión: este caso muestra la efectividad de ESPB como técnica experimental para control de dolor postoperatorio en fractura de escápula.

Abstract: Introduction: the erector spine plane block (ESPB) is a safe procedure, technically is less demanding than conventional thoracic regional anesthesia techniques. It is used for the treatment of acute and chronic pain. In the literature review, no reports of its use as a single technique in the acute pain of scapula fracture were found. Case presentation: ESPB is reported in a case as an experimental technique for controlling acute postoperative pain in scapula fractures with an application at the T2 level. It was performed postoperatively with a decrease in pain after 10 minutes and a score of zero on the analog pain scale. In this case, the ESPB was performed in the immediate postoperative period, achieving a total decrease in pain at 10 minutes, with subsequent pain control at 36 hours. Conclusion: this case shows the effectiveness of ESPB as an experimental technique for postoperative pain control in scapula fractures.

Postoperative pain management in the elderly. Literature review

Timely post-operative pain management in elderly patients is critically important. Given their physiological changes and comorbidities, management in this group of patients is different from the rest of the population. Knowledge of potentially inappropriate medications (Beers criteria) is relevant because of the presence of comorbidities in this population. Although acetaminophen continues to be safe, non-steroidal anti-inflammatory agents produce several adverse effects which need to be considered before they are used. On the other hand, opioids continue to be one of the pillars in analgesia, with due consideration of their adverse affects and interactions, and the need for dose adjustments. Adequate postoperative pain management prevents adverse effects and the risk of developing chronic pain.

El manejo oportuno del dolor en la población anciana durante el periodo posoperatorio es de vital importancia. Este grupo de pacientes, dado sus cambios fisiológicos y comorbilidades, requieren un manejo diferente al resto de la población. Es relevante conocer cuáles medicamentos son potencialmente inapropiados para su uso (criterios de Beers) ante las comorbilidades de esta población. Si bien el acetaminofén continúa siendo seguro, los antiinflamatorios no esteroideos causan varios efectos adversos que ameritan consideración antes de su uso; por su parte, los opioides siguen siendo uno de los pilares analgésicos, teniendo en cuenta sus efectos adversos y valorando la necesidad de ajuste de dosis e interacciones. El adecuado manejo del dolor posoperatorio previene desenlaces adversos y el riesgo de cronificación.

Estrategias no farmacológicas como adyuvantes para manejo del dolor agudo por punción en pediatría / Non-pharmacological strategies as adjuvants in needle associated acute pain management in pediatrics

El dolor en pediatría es un problema de salud pública que afecta al 78 % de pacientes hospitalizados y está frecuentemente asociado a punciones, por lo que es necesario un control rápido y efectivo. Existen en la actualidad estrategias psicológicas y físicas de estimulación sensorial para abordarlo. Se pretende describir el uso de estas como coadyuvantes en el manejo del dolor agudo por punción en pediatría. Se realizó una revisión narrativa de artículos originales y revisiones bibliográficas. El mecanismo del dolor involucra a las fibras C y a las fibras Aδ, que responden al dolor por punción. Entre las estrategias innovadoras se encuentra el dispositivo Buzzy®, que actúa mediante la teoría de compuerta del dolor, desviando la atención del dolor hacia un estímulo sensorial placentero (frío y vibración) que disminuye la intensidad en comparación con anestésicos locales (p < 0,001); así mismo, la realidad virtual desvía la atención del niño hacia un estímulo placentero, visual o auditivo, creando un ambiente tridimensional y produciendo analgesia por distracción en comparación al control (p < 0,05). El uso de estrategias no farmacológicas como coadyuvantes para el manejo de dolor por punción son efectivas para disminuir el dolor en el paciente pediátrico, así como el estrés y la ansiedad, tanto en los padres como en el personal de salud

Pediatric pain is a public healthcare problem present in 78 % of hospitalized patients and it is frequently associated to needles. Fast and effective controls are needed, therefore, sensory stimulation and psychological strategies have been developed. The aim of this study was to describe the use of non-pharmacological strategies as adjuvants in needle associated children pain management. A review was made searching through original articles and other reviews. Pain mechanism involves C fibers and Aδ fibers, which respond to short term needle pain. Buzzy® device is among the innovative physical strategies to relieve pain, which acts according to the pain threshold theory, diverting attention from pain to a pleasurable sensory stimulus (cold and vibration) decreasing its intensity when compared to topical anesthesia (p < 0,001). Meanwhile psychological strategies such as virtual reality divert the child's attention to a pleasant visual and auditory stimulus. It creates a tridimensional environment with an electronic device, decreasing pain while distracting the child when compared to the control group (p < 0,05). The use of innovative non-pharmacological strategies as adjuvants for needle pain management is effective decreasing children pain and reducing stress and anxiety in parents and healthcare workers

Impacto de la técnica anestésica en el dolor posoperatorio de cirugía reconstructiva mamaria / Impact of the anesthetic technique in postoperative pain in breast reconstructive surgery

OBJECTIVE: Our goal was to evaluate acute postoperative pain in patients undergoing breast reconstructive surgery with Deep Inferior Epigastric Perforator Artery (DIEP) flap technique. MATERIAL AND METHODS: A retrospective study was carried out in patients undergoing DIEP-flap breast reconstruction between January 2014 and December 2019. The main goal was the evaluation of acute postoperative pain through visual analogic pain scale (VAS) at rest (VASr) and movement (VASm) in the immediate postoperative period in post-anesthesia care unit (0h), at 24 h and at 48 h post-intervention and intravenous (IV) morphine con- sumption, depending on whether General Anesthesia (GA group) or Combined Anesthesia (CA group) was performed. Secon- dary outcomes were chronic pain incidence, perioperative complications, postoperative nausea and vomiting (PONV), reinterven- tion and readmission rate and lenght of hospital saty. RESULTS: Sixty seven patients were included, 24 in GA group and 43 in CA group. CA group showed better VASm values at 24 h postintervention (p = 0.01). Postoperative IV morphine continuous infusion was required for acute pain management in 10.4% of patients (25% in GA vs 2.3% in the CA group; p = 0.004). Chronic pain rate was 13.4% (25% in GA vs 7% in the CA group; p = 0.038). Patients with worse initial pain control (VASr > 3 at 0 h) showed a higher incidence of chronic pain (66.6% vs 9.6%; p = 0.008). GA group presented higher rate of postoperative complications (66.6% vs 34.9%; p = 0,012), as well reintervention rate (58.3% vs 30.2%; p = 0.025). A sub-analysis showed that of the 10 patients (5 in the AC and 5 in the AG group) who reported poor initial pain control (VASr > 3 at 0 h), those belonging to the AC group, the IV morphine requirements were lower at post-anesthesia care unit (2 (0-5) mg vs 16 (9.5-23) mg; p = 0.016) and throughout the hospitalization period (4 (0-6) vs 24 (17.5-49, 2); p = 0.008). CONCLUSIONS: Locorregional techniques could offer a better control of postoperative acute pain and a lower incidence of chronic pain, without assuming implying a higher risk of complications related to them in patients undergoing breast reconstructive surgery by DIEP flap technique.

OBJETIVO: El objetivo del estudio fue evaluar el dolor agudo posoperatorio en las pacientes sometidas a cirugía de reconstrucción mamaria mediante colgajo de la arteria perforante epigástrica inferior profunda (colgajo DIEP). MATERIAL Y MÉTODOS: Se revisaron retrospectivamente las pacientes intervenidas de reconstrucción mamaria con colgajo DIEP entre enero de 2014 y diciembre de 2019. El objetivo principal fue la valoración del dolor agudo posoperatorio mediante la escala visual analógica (EVA) en reposo (EVAr) y movimiento (EVAm) en el posoperatorio inmediato en la unidad de Reanimación (0 h), a las 24 h y a las 48 h post-intervención y el consumo de morfina endovenosa (ev), según si se realizó una Anestesia General (AG) o una Anestesia Combinada (AC). Los objetivos secundarios fueron: incidencia de dolor crónico posoperatorio, complicaciones peroperatorias, náuseas y vómitos posoperatorios (NVPO), tasa de reintervención y reingreso y estancia hospitalaria. RESULTADOS: Se incluyeron 67 pacientes, 24 en el grupo AG y 43 en el grupo AC. El grupo AC mostró un mejor control del dolor en movimiento a las 24 h (p = 0,01). Un 10,4% de las pacientes precisaron infusión de morfina endovenosa (ev) para control del dolor agudo posoperatorio en reposo (25% en el grupo AG vs 2,3% en el grupo AC; p = 0,004). La incidencia de dolor crónico fue del 13,4% (25% en el grupo AG vs 7% en el grupo AC; p = 0,038). Las pacientes con mal control inicial del dolor (EVAr > 3 a las 0 h) presentaron mayor incidencia de dolor crónico (66,6% vs 9,6%; p = 0,008). El grupo AG presentó mayor tasa de complicaciones posoperatorias (66,6% vs 34,9%; p = 0,012), así como tasa de reintervención (58,3% vs 30,2%; p = 0,025). Un subanálisis mostró que de las 10 pacientes (5 en el grupo AC y 5 en el grupo AG) que refirieron un mal control inicial del dolor (EVAr > 3 a las 0 h), las pertenecientes al grupo AC requirieron menos morfina ev en unidad de reanimación postanestésica (2 (0-5) mg vs 16 (9,5-23) mg; p = 0,016) y durante toda su hospitalización (4 (0-6) vs 24 (17,5-49,2); p = 0,008). CONCLUSIONES: Las técnicas locorregionales podrían ofrecer un mejor control del manejo del dolor agudo y una menor incidencia de dolor crónico, sin suponer un mayor riesgo de complicaciones relacionadas con ellos en pacientes sometidas a cirugía reconstructiva mamaria mediante técnica de colgajo DIEP.

Variability of PDYN and OPRK1 genes in four argentinian populations and its genetic association with clinical variables related to acute postsurgical pain / Variabilidad de los genes PDYN y OPRK1 en cuatro poblaciones argentinas y su asociación con variables clínicas relacionadas al dolor agudo post-quirúrgico

ABSTRACT Several population studies showed an association between variation in pain sensitivity and genetic polymorphisms located in Prodynorphin (PDYN) and Kappa Opioid Receptor (OPRK1) human genes. We analysed polymorphisms of these two genes to characterise their variation in Argentinian populations, as well as to evaluate their association with acute pain sensitivity. We studied 11 genetic markers in individuals from four locations in Argentina (Ciudad Autónoma de Buenos Aires, La Plata, Resistencia, and Misión Nueva Pompeya), calculated the population parameters, and evaluated the possible association among pain sensitivity, clinical, and genetic variables through a Generalised Estimating Equation model. High linkage disequilibrium was observed in the four populations for both genes, and significant differences were found among frequencies of Argentinian populations and those from other continents reported in the 1000 Genomes Project. Four PDYN gene polymorphisms from 3´ untranslated region and exon 4 showed association with acute pain sensitivity. One genotype of each of these polymorphisms was associated with a higher pain sensitivity, probably related with the activation of the N-methyl-D-aspartate (NMDA) receptors. We found a strong association with acute pain for the following clinical variables: 1) time after surgery, 2) intravenous klosidol supplied every 8 h, and 3) type of incision. Our results highlight the importance of a regional study of genetic variants which influence pain sensitivity and analgesic response.

RESUMEN La asociación entre la sensibilidad al dolor y los polimorfismos que presentan los genes humanos de prodinorfina (PDYN) y receptor opioide kappa (OPRK1) se ha evidenciado en distintos estudios poblacionales. Con el objetivo de caracterizar la variación de estos genes y evaluar su asociación con dolor agudo en la población argentina, analizamos 11 polimorfismos en individuos provenientes de cuatro localidades argentinas (Ciudad Autónoma de Buenos Aires, La Plata, Resistencia, y Misión Nueva Pompeya). Calculamos los parámetros poblacionales y evaluamos la posible asociación entre sensibilidad al dolor, variables clínicas y variables genéticas a través de un modelo de ecuación generalizada de estimación. Se observó alto desequilibrio de ligamiento para ambos genes en las cuatro poblaciones analizadas, y se encontraron diferencias significativas entre las frecuencias de poblaciones argentinas y las reportadas en el Proyecto 1000 Genomes para poblaciones de otros continentes. Cuatro polimorfismos de la región 3´UTR y el exón 4 de PDYN mostraron asociación con la sensibilidad al dolor agudo. En cada uno de estos polimorfismos, un genotipo resultó asociado con alta sensibilidad al dolor, probablemente en relación con la activación de receptores N-metil-D-aspartato (NMDA). Encontramos una fuerte asociación con dolor agudo para las siguientes variables clínicas: 1) tiempo post-cirugía, 2) administración intravenosa de klosidol cada 8 h, y 3) tipo de incisión. Nuestros resultados resaltan la importancia de realizar estudios regionales de variables genéticas que influyen en la sensibilidad al dolor y la respuesta analgésica.

Tratamiento del dolor agudo por lesión traumática en pacientes con adicciones / Treatment of acute pain from traumatic injury in patients with addictions

Resumen: Introducción: Las guías actuales para el manejo del dolor en pacientes con adicciones no contemplan el tratamiento del dolor agudo. Objetivo: Describir los esquemas de tratamiento analgésico y la dosis promedio de opioide requerida para control del dolor agudo en pacientes consumidores de sustancias psicoactivas hospitalizados en un Servicio de Traumatología. Material y métodos: Se realizó un estudio descriptivo, retrospectivo y transversal a través de la revisión de expedientes de pacientes con lesión traumática y antecedente de consumo de sustancias que fueron tratados bajo un esquema de analgesia multimodal. Resultados: Se incluyeron 75 pacientes con edad promedio de 32 (± 9.6) años. El opioide indicado con mayor frecuencia fue la buprenorfina en 48% (dosis media 644 μg/24h), seguida de la morfina en 28% (dosis media 20 mg/24h) y tramadol en 24% de los pacientes (dosis media 195 mg/24h). No hubo diferencia estadísticamente significativa (p < 0.05) en el control del dolor entre los tres grupos, excepto que la intensidad del dolor en el grupo de la morfina fue mayor a las 24 horas. Conclusión: Los pacientes tratados con buprenorfina tuvieron mejor control del dolor en comparación con el grupo de morfina, aunque requirieron dosis 40% mayores a las recomendadas para pacientes con trauma.

Abstract: Introduction: Current guidelines for pain management in addiction patients do not address acute pain care. Objective: To describe the analgesic treatment schemes and the average dose of opioid required for the control of acute pain in psychoactive substance-using patients hospitalized in a trauma department. Material and methods: A descriptive, retrospective, and cross-sectional study was carried out by reviewing the records of patients with traumatic injury and a history of substance use who were treated under a multimodal analgesia scheme. Results: 75 patients with a mean age of 32 (± 9.6) years were included. The most frequently prescribed opioid was buprenorphine in 48% (mean dose 644 µg/24h), followed by morphine in 28% (mean dose 20 mg/24h) and tramadol in 24% of patients (mean dose 195 mg/24h). There was not statistically significant difference (p < 0.05) in pain control between the three groups, except that the intensity of pain in the morphine group was greater at 24 hours. Conclusion: The patients treated with buprenorphine had better pain control compared to the morphine group, although doses 40% higher than those recommended for trauma patients were required.

Infusión intravenosa de ketamina a bajas dosis durante cirugía de artrodesis de columna. Una estrategia en el manejo del dolor agudo posoperatorio / Intravenous ketamine infusión at low doses during spinal arthodesis surgery. A strategy in acute postoperative pain management

INTRODUCTION: Acute postoperative pain is a complex problem given the pathophysiological characteristics, increasing health costs and complications and hindering recovery[1],[2]. Spinal arthrodesis is one of the most painful surgical procedures, presenting intense and disabling pain[3],[4]. Multimodal analgesia has been the tool with the best results, based on opioids; however, the combined use of drugs and dependence on opiates are important consequences. Therefore, the analgesic behavior during the use of subanesthetic doses of ketamine is described in the patients undergoing this procedure. METHODOLOGY: A prospective case series study was conducted from January-December 2019, with patients undergoing spinal arthrodesis who met the inclusion criteria, at the Hernando Moncaleano Perdomo University Hospital, Neiva. A univariate statistical analysis of all the variables is performed, with a joint interpretation of the results. RESULTS: A total of 17 patients underwent surgery, one of whom was excluded due to complications related to the surgical material. 88% of the patients showed evaluations of mild or absent pain in at least 4 times, with a number of morphine rescues in 24 hours of 1-2 per patient and patient ambulation in 90% on the first day. CONCLUSIONS. Postoperative spinal arthrodesis patients receiving intravenous ketamine infusion-based analgesia at subanesthetic doses showed mild or absent pain scores at almost all times.

INTRODUCCIÓN: El dolor agudo postoperatorio es un problema complejo dada las características fisiopatológicas, aumentando los costos en salud y las complicaciones y dificultando la recuperación[1],[2]. La artrodesis de columna, es uno de los procedimientos quirúrgicos más dolorosos, presentando un dolor intenso e incapacitante[3],[4]. La analgesia multimodal ha sido la herramienta con mejores resultados, tomando como base los opioides; sin embargo, el uso combinado de fármacos y la dependencia a opiáceos son consecuencias importantes. Por lo anterior, se describe el comportamiento analgésico durante el uso de dosis subanestésicas de ketamina en los pacientes llevados a dicho procedimiento. METODOLOGÍA: Se realiza un estudio tipo serie de casos, prospectivo de enero-diciembre de 2019, con los pacientes llevados a artrodesis de columna que cumplieron con los criterios de inclusión en el Hospital Universitario Hernando Moncaleano Perdomo, Neiva. Se realiza un análisis estadístico univariado de la totalidad de las variables, con una interpretación conjunta de los resultados. RESULTADOS: Se intervinieron un total de 17 pacientes, uno de los cuales fue excluido por complicaciones relacionadas con el material quirúrgico. El 88% de los pacientes mostraron valoraciones de dolor leve o ausente en al menos 4 tiempos, con número de rescates de morfina en 24 h de 1-2 por paciente y deambulación de los pacientes en el 90% en el primer día. CONCLUSIONES: Los pacientes posoperatorios de artrodesis de columna que recibieron analgesia basada en infusión endovenosa de ketamina a dosis subanestésicas mostraron valoraciones de dolor leve o ausente, en casi todos los tiempos.

Severe acute postoperative pain self-reported by children after ambulatory surgeries: a cohort study / Dor aguda pós-operatória intensa autorreferida por crianças após cirurgias ambulatoriais: um estudo de coorte / Dolor postoperatorio agudo severo autoinformado por niños después de cirugías ambulatorias: un estudio de cohort

ABSTRACT Objectives: to estimate the incidence and the risk factors for severe acute postoperative pain self-reported on the first day after hospital discharge. Methods: cohort study with 279 children from both sexes (5-12 years old), indicated for ambulatory surgery in two Brazilian hospitals. Children were assessed at the pre-surgery, immediate postoperative and first postoperative day. Faces Pain Scale-Revised and Yale Preoperative Anxiety Scale Modified were used. Severe postoperative pain was defined as score ≥6. Cox regression analyses were used. Results: the incidence of severe postoperative pain was 15.8% (95%CI:10.7%-20.4%) on the first postoperative day. Preoperative anxiety (HR=2.23; p=0.049), severe preoperative pain (HR=2.78; p=0.031) and having undergone two surgical procedures (HR=2.91; p=0.002) were associated with severe postoperative pain. Conclusions the incidence of severe postoperative pain self-reported after hospital discharge was high. Anxiety and severe preoperative pain, in addition to performing two surgical procedures at the same time were confirmed as risk factors.

RESUMO Objetivos: estimar a incidência e os fatores de risco para dor pós-operatória intensa autorreferida no primeiro dia pós-alta. Métodos: estudo de coorte com 279 crianças de ambos os sexos (5-12 anos), com indicação para cirurgia ambulatorial em dois hospitais brasileiros. As crianças foram avaliadas no pré-operatório, pós-operatório imediato e primeiro dia pós-alta. As Escala de Faces de Dor Revisada e Escala de Ansiedade Pré-operatória de Yale Modificada foram utilizadas. Dor aguda pós-operatória foi definida como pontuação ≥6. Análises de regressão de Cox foram realizadas. Resultados: a incidência de dor pós-operatória foi de 15,8% (IC95%: 10,7%-20,4%) no primeiro dia pós-alta. Ansiedade pré-operatória (HR=2,23; p=0,049), dor préoperatória intensa (HR=2,78; p=0,031) e ter sido submetido a dois procedimentos cirúrgicos (HR=2,91; p=0,002) foram associados à dor pós-operatória. Conclusões: a incidência de dor intensa autorreferida no pós-operatório foi elevada. Ansiedade, dor pré-operatória intensa e submissão a dois procedimentos cirúrgicos foram confirmados como fatores de risco.
