RESUMEN

Opioid use disorder (OUD) is an ongoing public health concern in the United States, and relatively little work has addressed how genetic background contributes to OUD. Understanding the genetic contributions to oxycodone-induced analgesia could provide insight into the early stages of OUD development. Here, we present findings from a behavioral phenotyping protocol using several inbred strains from the Hybrid Rat Diversity Panel. Our behavioral protocol included a modified "up-down" von Frey procedure to measure inherent strain differences in the sensitivity to a mechanical stimulus on the hindpaw. We also performed the tail immersion assay, which measures the latency to display tail withdrawal in response to a hot water bath. Initial withdrawal thresholds were taken in drug-naïve animals to record baseline thermal sensitivity across the strains. Oxycodone-induced analgesia was measured after administration of oxycodone over the course of 2 h. Both mechanical and thermal sensitivity are shaped by genetic factors and display moderate heritability (h2 = 0.23-0.40). All strains displayed oxycodone-induced analgesia that peaked at 15-30 min and returned to baseline by 2 h. There were significant differences between the strains in the magnitude and duration of their analgesic response to oxycodone, although the heritability estimates were quite modest (h2 = 0.10-0.15). These data demonstrate that genetic background confers differences in mechanical sensitivity, thermal sensitivity, and oxycodone-induced analgesia.

RESUMEN

BACKGROUND: Some patients with end stage renal disease are or will become narcotic-dependent. Chronic narcotic use is associated with increased graft loss and mortality following kidney transplantation. We aimed to compare the efficacy of continuous flow local anesthetic wound infusion pumps (CFLAP) with patient controlled analgesia pumps (PCA) in reducing inpatient narcotic consumption in patients undergoing kidney transplantation. MATERIALS AND METHODS: In this single-center, retrospective analysis of patients undergoing kidney transplantation, we collected demographic and operative data, peri-operative outcomes, complications, and inpatient oral morphine milligram equivalent (OME) consumption. RESULTS: Four hundred and ninety-eight patients underwent kidney transplantation from 2020 to 2022. 296 (59%) historical control patients received a PCA for postoperative pain control and the next 202 (41%) patients received a CFLAP. Median age [53.5 vs. 56.0 years, p = .08] and BMI [29.5 vs. 28.9 kg/m2, p = .17] were similar. Total OME requirement was lower in the CFLAP group [2.5 vs. 34 mg, p < .001]. Wound-related complications were higher in the CFLAP group [5.9% vs. 2.7%, p = .03]. Two (.9%) patients in the CFLAP group experienced cardiac arrhythmia due to local anesthetic toxicity and required lipid infusion. CONCLUSIONS: Compared to PCA, CFLAP provided a 93% reduction in OME consumption with a small increase in the wound-related complication rate. The utility of local anesthetic pumps may also be applicable to patients undergoing any unilateral abdominal or pelvic incision.

RESUMEN

Video-assisted thoracic surgery (VATS) is currently used for the repair of pectus excavatum. Analgesia after thoracic surgery can be provided with nerve blocks, intravenous drugs, or neuraxial techniques. Serratus posterior superior intercostal plane block (SPSIPB) is a novel interfascial plane block and it is performed between the serratus posterior superior muscle and the intercostal muscles at the level of the second and third ribs. In this case, we present our successful analgesic experience with SPSIPB in a patient who underwent minimally invasive pectus excavatum repair with a VATS technique.

RESUMEN

ABSTRACT: Sternal wound complications following sternotomy need a multidisciplinary approach in high-risk postoperative cardiac surgical patients. Poorly controlled pain during surgical management of such wounds increases cardiovascular stress and respiratory complications. Multimodal analgesia including intravenous opioids, non-opioid analgesics, and regional anesthesia techniques, like central neuraxial blocks and fascial plane blocks, have been described. Pecto-intercostal fascial plane block (PIFB), a novel technique, has been effectively used in patients undergoing cardiac surgery. Under ultrasound (US) guidance PIFB is performed with the aim of depositing local anesthetic between two superficial muscles, namely the pectoralis major muscle and the external intercostal muscle. The authors report a series of five cases where US-guided bilateral PIFB was used in patients undergoing sternal wound debridement. Patients had excellent analgesia intraoperatively as well as postoperatively for 24 hours with minimal requirement of supplemental analgesia. None of the patients experienced complications due to PIFB administration. The authors concluded that bilateral PIFB can be effectively used as an adjunct to multimodal analgesia with general anesthesia and as a sole anesthesia technique in selected cases of sternal wound debridement.

RESUMEN

Introducción: En la literatura existen pocas referencias que comparen las distintas alternativas disponibles para controlar el dolor enel postoperatorio inmediato de la apendicitis aguda pediátrica (AAP).Material y métodos: Comparación prospectiva del perfil anal-gésico y emético del ibuprofeno y el metamizol intravenosos en elpostoperatorio inmediato de la AAP, para lo cual se recurre a unamuestra de pacientes operados en 2021 en nuestro centro. Los participantes fueron reclutados a su llegada a Urgencias, obteniéndoseconfirmación histopatológica del diagnóstico en todos ellos. La evaluación del dolor se llevó a cabo cada 8 horas tras la cirugía medianteescalas analógicas visuales validadas, con valoraciones entre los 0 ylos 10 puntos. Se realizó un ANOVA de las medidas repetidas entrelos dos grupos para comparar la evolución del dolor en las 48 horasposteriores a la cirugía.Resultados: La muestra estaba compuesta por un total de 95 pacientes (65% de ellos varones) con una edad media de 9,7 años (DT:3,14). 41 pacientes fueron tratados con ibuprofeno (grupo 1) y 54 conmetamizol (grupo 2). No se hallaron diferencias significativas en lo querespecta al dolor, ni en las comparaciones de las mediciones puntuales,ni en su evolución en las 48 horas posteriores a la cirugía (p= 0,58). Unavez realizado el ajuste correspondiente a la terapia de fluidos recibida,los niños del grupo metamizol tuvieron significativamente más episodioseméticos y necesitaron significativamente más dosis de ondansetrón.Conclusiones: En nuestra cohorte, el ibuprofeno tuvo una eficaciaanalgésica similar y un mejor perfil emético que el metamizol en elpostoperatorio inmediato de la AAP. Se hacen necesarios nuevos estudiosprospectivos, adecuadamente controlados y con mayor tamaño muestralque validen estos hallazgos.(AU)


Background: Literature comparing different alternatives for paincontrol in the immediate postoperative period of pediatric acute appendicitis (PAA) is scarce.Materials and methods: We prospectively compared the analgesicand emetogenic profile of intravenous ibuprofen and metamizole in theimmediate postoperative period of PAA. For this purpose, we used asample of patients operated on in 2021 in our center. Participants wererecruited on arrival at the Emergency Department and histopathologi-cal confirmation of the diagnosis was obtained in all of them. Pain wasevaluated every 8 hours after the surgery with validated visual analogscales ranging from 0 to 10 points. Repeated measures ANOVA wasused to compare the evolution of pain in the 48 hours after surgerybetween the two groups. Results: The sample included 95 patients (65% males) with a meanage of 9.7 years (sd: 3.14). 41 patients were treated with Ibuprofen(group 1) and 54 with metamizole (group 2). No significant differ-ences were found in the level of pain either in the comparisons of pointmeasurements or in its evolution in the 48 hours after surgery (p= 0.58).After adjusting for the received fluid therapy, children in the metamizolegroup had significantly more emetic episodes and needed significantlymore doses of ondansetron. Conclusions: In our cohort, ibuprofen had a similar analgesic ef-ficacy and a better emetogenic profile than metamizole in the immediatepostoperative period of PAA. Future prospective, adequately controlledstudies with larger sample sizes are needed to validate these findings.(AU)

RESUMEN

Antecedentes y objetivos: Las infiltraciones epidurales (IEE) constituyen una alternativa en el tratamiento del síndrome de radiculopatía lumbosacro (SRL). El objetivo de estudio es evaluar la eficacia de las IEE en la intensidad del dolor, mejora de la recuperación funcional y retorno a la actividad laboral. Material y métodos: Se realizó un estudio prospectivo en una cohorte de 100 pacientes consecutivos remitidos a la unidad del dolor por SRL de más de 3 meses de duración. Se analizó la eficacia de las inyecciones de corticoides y anestésicos locales por diferentes vías (interlaminar, caudal y transforaminal) a los 15 días, un mes y 3 meses de la infiltración, en cuanto a la intensidad del dolor mediante la escala analógica visual (EAV), evolución del grado de discapacidad y la reincorporación laboral. Resultados: Noventa y nueve pacientes se incluyeron en el estudio. El 46,5% fueron varones y el 53,5% mujeres. La edad media fue de 57,47±11,1 años. En la mayoría (58,6%) de los casos se optó por la vía caudal, seguida de la transforaminal (23,2%), e interlaminar (18,2%). Las IEE produjeron una reducción significativa del dolor en todos los periodos estudiados (EAV: 7,78±1,5 basal; 6,2±0,9 a los 15 días; 6,3±1,2 al mes; 6,15±1,3 a los 3 meses; p<0,05). La vía de acceso más eficaz fue la transforaminal. El 70% de los pacientes en situación de incapacidad laboral retornaron a su trabajo tras el tratamiento. Discusión y conclusiones: El tratamiento mediante las IEE redujo la intensidad del dolor por SRL, mejoró la situación funcional y la reincorporación a la actividad laboral.(AU)


Backgrund and objective: Epidural infiltrations are used for treatment of low back pain and sciatica. linked to lumbar radiculopathy (lumbosacral radicular syndrome). This study evaluates the efficacy of epidural infiltration by different routes to reduce pain intensity, disability and return to work. Methods: Is a prospective observational study in one hundred consecutive patients sent to pain unit for severe lumbo-sacral radiculopaty. We analyze the efficacy on pain relief (Visual Analogue Scale) and funcional status at two weeks, one month, and three months after epidural injection of local anesthetics and esteroids with differents approachs (interlaminar, caudal and transforaminal). Results: Ninety nine patients (46.5% men, 53.5 women) were finally enrrolled in the study. Mean age was 57.47±11.1 years. The caudal approach was used in 58.6% patients, 23.2% transforaminal approach, and 18.2% interlaminar approach. A significant pain relief was found in all times studied (EAV 7.48±1.5 basal; 6.2±0,9 at 15 days; 6.3±1.2 at one month; 6.15±1.3 at 3 months, P<.05). Transforaminal approach was superior to caudal or interlaminal. Seventy percent in time off work patients returned to work after epidural inyections. Conclusions: Epidural local anesthetics with esteroids injections for lumbo-sacral radiculopathy were effective for low back pain, improved functional status and promoted return to work. Transforaminal approach is superior to others.(AU)

RESUMEN

PURPOSE: Rib fracture(s) is a common and painful injury often associated with significant morbidity (e.g., respiratory complications) and high mortality rates, especially in the elderly. Risk stratification and prompt implementation of analgesic pathways using a multimodal analgesia approach comprise a primary endpoint of care to reduce morbidity and mortality associated with rib fractures. This narrative review aims to describe the most recent evidence and care pathways currently available, including risk stratification tools and pharmacologic and regional analgesic blocks frequently used as part of the broadly recommended multimodal analgesic approach. SOURCE: Available literature was searched using PubMed and Embase databases for each topic addressed herein and reviewed by content experts. PRINCIPAL FINDINGS: Four risk stratification tools were identified, with the Study of the Management of Blunt Chest Wall Trauma score as most predictive. Current evidence on pharmacologic (i.e., acetaminophen, nonsteroidal anti-inflammatory drugs, gabapentinoids, ketamine, lidocaine, and dexmedetomidine) and regional analgesia (i.e., thoracic epidural analgesia, thoracic paravertebral block, erector spinae plane block, and serratus anterior plane block) techniques was reviewed, as was the pathophysiology of rib fracture(s) and its associated complications, including the development of chronic pain and disabilities. CONCLUSION: Rib fracture(s) continues to be a serious diagnosis, with high rates of mortality, development of chronic pain, and disability. A multidisciplinary approach to management, combined with appropriate analgesia and adherence to care bundles/protocols, has been shown to decrease morbidity and mortality. Most of the risk-stratifying care pathways identified perform poorly in predicting mortality and complications after rib fracture(s).


RéSUMé: OBJECTIF: Les fractures des côtes sont des blessures courantes et douloureuses souvent associées à une morbidité importante (p. ex., complications respiratoires) et à des taux de mortalité élevés, surtout chez les personnes âgées. La stratification des risques et la mise en œuvre rapide de voies analgésiques à l'aide d'une approche d'analgésie multimodale constituent un critère d'évaluation principal des soins visant à réduire la morbidité et la mortalité associées aux fractures des côtes. Ce compte rendu narratif a pour objectif de décrire les données probantes les plus récentes et les parcours de soins actuellement disponibles, y compris les outils de stratification des risques et les blocs analgésiques pharmacologiques et régionaux fréquemment utilisés dans le cadre de l'approche analgésique multimodale largement recommandée. SOURCES: La littérature disponible a été recherchée à l'aide des bases de données PubMed et Embase pour chaque sujet abordé dans le présent compte rendu et examinée par des expert·es en contenu. CONSTATATIONS PRINCIPALES: Quatre outils de stratification des risques ont été identifiés, le score de l'Étude de la prise en charge des traumatismes contondants de la paroi thoracique (Study of the Management of Blunt Chest Wall Trauma) étant le plus prédictif. Les données probantes actuelles sur les techniques d'analgésie pharmacologiques (c.-à-d. acétaminophène, anti-inflammatoires non stéroïdiens, gabapentinoïdes, kétamine, lidocaïne et dexmédétomidine) et d'analgésie régionale (c.-à-d. analgésie péridurale thoracique, bloc paravertébral thoracique, bloc du plan des muscles érecteurs du rachis et bloc du plan du muscle grand dentelé) ont été examinées, de même que la physiopathologie de la ou des fractures des côtes et de leurs complications associées, y compris l'apparition de douleurs chroniques et d'incapacités. CONCLUSION: Les fractures des côtes continuent d'être un diagnostic grave, avec des taux élevés de mortalité, de développement de douleurs chroniques et d'invalidité. Il a été démontré qu'une approche multidisciplinaire de la prise en charge, combinée à une analgésie appropriée et à l'adhésion aux ensembles et protocoles de soins, réduit la morbidité et la mortalité. La plupart des parcours de soins de stratification des risques identifiés sont peu performants pour prédire la mortalité et les complications après une ou plusieurs fractures de côtes.

RESUMEN

BACKGROUND: Procedural sedation and analgesia are commonly used in the Emergency Departments. Despite this common need, there is still a lack of options for adequate and safe analgesia and sedation in children. The objective of this study was to evaluate whether intranasal dexmedetomidine could provide more effective analgesia and sedation during a procedure than intranasal esketamine. METHODS: This was a double-blind equally randomized (1:1) superiority trial of 30 children aged 1-3 years presenting to the Emergency Department with a laceration or a burn and requiring procedural sedation and analgesia. Patients were randomized to receive 2.0 mcg/kg intranasal dexmedetomidine or 1.0 mg/kg intranasal esketamine. The primary outcome measure was highest pain (assessed using Face, Legs, Activity, Cry, Consolability scale (FLACC)) during the procedure. Secondary outcomes were sedation depth, parents' satisfaction, and physician's assessment. Comparisons were done using Mann-Whitney U test (continuous variables) and Fisher's test (categorical variables). RESULTS: Adequate analgesia and sedation were reached in 28/30 patients. The estimated sample size was not reached due to changes in treatment of minor injuries and logistical reasons. The median (IQR) of highest FLACC was 1 (0-3) with intranasal dexmedetomidine and 5 (2-6.75) with intranasal esketamine, (p-value 0.09). 85.7% of the parents with children treated with intranasal dexmedetomidine were "very satisfied" with the procedure and sedation compared to the 46.2% of those with intranasal esketamine, (p-value 0.1). No severe adverse events were reported during this trial. CONCLUSIONS: This study was underpowered and did not show any difference between intranasal dexmedetomidine and intranasal esketamine for procedural sedation and analgesia in young children. However, the results support that intranasal dexmedetomidine could provide effective analgesia and sedation during procedures in young children aged 1-3 years with minor injuries.

RESUMEN

Accumulating evidence supports the notion that microglia play versatile roles in different chronic pain conditions. However, therapeutic strategies of chronic pain by targeting microglia remain largely overlooked. This study seeks to develop a miRNA-loaded nano-delivery system by targeting microglia, which could provide a decent and long-lasting analgesia for chronic pain. Surface aminated mesoporous silica nanoparticles were adopted to load miR-26a-5p, a potent analgesic miRNA, by electrostatic adsorption, which can avoid miR-26a-5p is rapidly released and degraded. Then, targeting peptide MG1 was modified on the surface of aminated mesoporous silica particles for microglia targeting. In peripheral nerve injury induced neuropathic pain model, a satisfactory anti-allodynia effect with about 6 weeks pain-relief duration were achieved through targeting microglia strategy, which decreased microglia activation and inflammation by Wnt5a, a non-canonical Wnt pathway. In inflammatory pain and chemotherapy induced peripheral neuropathic pain, microglia targeting strategy also exhibited more efficient analgesia and longer pain-relief duration than others. Overall, we developed a microglia-targeting nano-delivery system, which facilitates precisely miR-26a-5p delivery to enhance analgesic effect and duration for several chronic pain conditions.

RESUMEN

PURPOSE: The objective of this study was to perform a retrospective cohort analysis, in which we measured the association of an acute pain service (APS)-driven multimodal analgesia protocol that included preoperative intrathecal morphine (ITM) compared to historic controls (i.e., surgeon-driven analgesia protocol without ITM) with postoperative opioid use. METHODS: This was a retrospective cohort study in which the primary objective was to determine whether there was a decrease in median 24-h opioid consumption (intravenous morphine equivalents [MEQ]) among robotic nephrectomy patients whose pain was managed by the surgical team prior to the APS, versus pain managed by APS. Secondary outcomes included opioid consumption during the 24-48 h and 48-72 h period and hospital length of stay. To create matched cohorts, we performed 1:1 (APS:non-APS) propensity score matching. Due to the cohorts occurring at the different time periods, we performed a segmented regression analysis of an interrupted time series. RESULTS: There were 76 patients in the propensity-matched cohorts, in which 38 (50.0%) were in the APS cohort. The median difference in 24-h opioid consumption in the pre-APS versus APS cohort was 23.0 mg [95% CI 15.0, 31.0] (p < 0.0001), in favor of APS. There were no differences in the secondary outcomes. On segmented regression, there was a statistically significant drop in 24-h opioid consumption in the APS cohort versus pre-APS cohort (p = 0.005). CONCLUSIONS: The implementation of an APS-driven multimodal analgesia protocol with ITM demonstrated a beneficial association with postoperative 24-h opioid consumption following robot-assisted nephrectomy.

RESUMEN

OBJECTIVE: To compare the efficacy of preemptive ibuprofen, local ketamine, and their combination in managing postoperative pain and trismus following third molar surgery. MATERIALS AND METHODS: One hundred patients were randomly divided into 4 groups. The Intrafen Group had their impacted third molars surgically removed under local anesthesia after receiving intravenous (IV) ibuprofen for preemptive effect. The Ketamine Group received an IV placebo before the surgery, and the extraction process was completed with a local anesthetic-ketamine combination. The Combined Group received preemptive IV ibuprofen before the procedure, and the surgery was performed with a local anesthetic-ketamine combination. The Control Group received an IV placebo before the procedure and then had their impacted third molars removed under local anesthesia. The Visual Analogue Scale (VAS) values, corresponding to the patients' pain levels at the 2nd and 12th postoperative hours and the total amount of analgesic dose used in the first 24 hours, were recorded, and evaluated. The maximum mouth opening of the patients was measured immediately before the procedure, and on the second and seventh postoperative days. The level of patient satisfaction in all groups was assessed during the procedure. RESULTS: The mean VAS value corresponding to the second-hour pain level of the combined group was statistically significantly lower than the other groups (P = .003). A statistically significant difference was found in the mean VAS values corresponding to the pain levels of the groups, favoring the combined group compared to the other groups (P ≤ .001). A significant difference was observed between the VAS difference values corresponding to the pain levels of the Intrafen group and the Ketamine group, favoring the Intrafen group (P = .038). The Ketamine group consumed the most analgesic on average over the first 24 hours, whereas the Combined group consumed the least. No statistically significant difference was found between the mean trismus levels of the groups on days 0-2 (P = .528) and days 0-7 (P = .129). The intraoperative patient satisfaction level of the combined group was significantly higher than that of the other groups (P = .030). CONCLUSION: Preemptive Intrafen is an effective regimen for postoperative pain management and is superior to the local anesthetic-ketamine regimen. The most effective method to reduce postoperative pain following third molar surgery is to use a combination of these 2 regimens. However, none of the treatment methods used in the study had a positive effect on postoperative trismus.

RESUMEN

Inadequate antinociception during skull pin fixation may cause hemodynamic instability in intracranial surgery. The optimal concentration of remifentanil to provide adequate antinociception and stable hemodynamics during skull pin fixation under analgesia nociception index monitoring is unknown. This study is to assess the 90% effective concentration of remifentanil for skull pin fixation under hemodynamic and analgesia nociception index monitoring. Twenty-six patients were enrolled for intracranial surgery, anesthesia was induced and maintained under total intravenous anesthesia using target-controlled infusion for remifentanil and propofol under analgesia nociception index and bispectral index monitoring. Skull pin fixation was performed at different effect-site concentrations of remifentanil required for Dixon's up-and-down method with a step size of 0.5 ng/ml under bispectral index 40-60. Inadequate antinociception is defined when either ANI < 30 or > 20% in hemodynamic changes from baseline (e.g. heart rate > 100 beats/min, or blood pressure > 180/100 mmHg) and the effect-site concentration of remifentanil is considered as failure. It is considered success as ANI > 30 and < 20% hemodynamic changes from baseline simultaneously. Seven pairs of failure/success were used for probit analysis. The 90% effective concentration of remifentanil for skull pin fixation with adequate antinociception and hemodynamic stability was 4.7 ng/ml.

RESUMEN

The practice of labor analgesia is highly variable in India. Parturients are often prescribed mild opioids (tramadol and pethidine). Erector spinae plane blocks can provide widespread analgesia covering multiple dermatomes. After a process evaluation to introduce safe and effective labor analgesia mandated due to poor efficacy of the standard care, erector spinae plane analgesia was offered to nulliparous parturients. The procedure was performed under ultrasound guidance at the lumbar L4 level in 10 patients. Outcomes included pain scores. There was a major reduction in labor pain. Erector spinae plane blocks can be part of a sustainable and effective labor analgesia service.

RESUMEN

INTRODUCTION: The subtransverse process interligamentary (STIL) plane block is an emerging interfascial plane block that has garnered attention for its potential to provide effective postoperative analgesia for breast and thoracic surgeries. However, a direct comparative assessment between the STIL plane block and the paravertebral block is currently lacking. Consequently, our study aims to assess the analgesic efficacy of the STIL block in comparison to paravertebral block for patients undergoing video-assisted thoracoscopic surgery (VATS). METHODS AND ANALYSIS: This study is a randomised, parallel-controlled, double-blind, non-inferiority trial, with the goal of enrolling 114 participants scheduled for uniportal VATS at Shanghai Pulmonary Hospital. Participants will be randomly assigned in a 1:1 ratio through block randomisation to receive either the STIL plane block (n=57) or the paravertebral block (n=57). The primary outcome of the study is the area under the curve of Numerical Rating Scale(NRS) scores recorded over a 48-hour period following the surgical procedure. Secondary outcomes encompass the evaluation of Quality of Recovery-40, cumulative sufentanil consumption, serum inflammatory factors, rescue medication usage, the incidence of adverse events and the patient satisfaction scores. ETHICS AND DISSEMINATION: This study has received approval from the Medical Ethics Committee of Shanghai Pulmonary Hospital (approval no. L22-329). Written informed consent will be obtained from all participants. The findings will be submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: ChiCTR2200066909.

RESUMEN

Scapulothoracic arthrodesis (STA) surgery is performed to stabilize the scapula in patients with facioscapulohumeral dystrophy (FSHD). Postoperative pain could be a major problem even while using erector spinae plane block (ESPB). We performed a preoperative ESPB with an intraoperative ESPB catheter, but rescue analgesia was needed for pain in the periscapular area in the postoperative period. The patient's pain score was reduced by applying an ultrasound-guided dorsal scapular nerve (DSN) and long thoracic nerve (LTN) block. Selective DSN and LTN blocks can be effective in enhancing postoperative analgesia in STA surgery.
