Effect of Opioid Versus Non-Opioid Analgesia on Surgical Pleth Index and Biomarkers of Surgical Stress During Neurosurgery for Brain Tumors: Preliminary Findings.
Stress response to surgery is mediated by the sympathetic nervous system and manifests as changes in hemodynamic and neuroendocrine parameters. Recently, the surgical pleth index (SPI) is employed for objective and continuous monitoring of nociceptive response during surgery. Opioids are the mainstay of managing stress response to nociception during the perioperative period. However, due to the well-known adverse effects of opioids, α2 agonists are increasingly used to ablate stress response and reduce opioid usage. ⋯ The stress response to surgery during craniotomy for brain tumors is similar with opioid (fentanyl) and non-opioid (dexmedetomidine) analgesia as assessed by SPI and blood markers such as cortisol, glucose, and pH.

Chronic opioid use in the United States is a well-recognized public health concern with many negative downstream consequences. Few data exist regarding the use of preoperative opioids in relation to outcomes after elective colorectal surgery. ⋯ Although preoperative opioid use was not associated with an increased rate of surgical site infections or readmissions, it was independently associated with an increased hospital length of stay. Innovative perioperative strategies will be necessary to eliminate these differences for patients on chronic opioids. See Video Abstract at http://links.lww.com/DCR/B280. EFECTOS DEL CONSUMO CRÓNICO DE OPIOIDES EN EL PREOPERATORIO CON RELACIÓN A LAS INFECCIONES DE LA HERIDA QUIRÚRGICA, LA DURACIÓN DE LA ESTADÍA Y LA READMISIÓN: El consumo crónico de opioides en los Estados Unidos es un problema de salud pública bien reconocido a causa de sus multiples consecuencias negativas ulteriores. Existen pocos datos sobre el consumo de opioides en el preoperatorio relacionado con los resultados consecuentes a una cirugía colorrectal electiva.El propósito es determinar si el consumo crónico de opioides antes de la cirugía colorrectal se asocia con un detrimento en los resultados postoperatorios.Revisión retrospectiva de datos administrativos complementada por la revisión de un gráfico individual.Ejercicio durante la formación de multiples residentes en cirugía colorrectal enTodos los pacientes de cirugía colorrectal electiva durante un período de 3 años (2011-2014).El uso de opioides se estratificó en función de la dosis total de equivalentes de miligramos de morfínicos (uso previo, uso esporádico [> 0-15 mg / día], uso regular (> 15-45 mg / día) y uso frecuente (> 45 mg / día)). Los resultados primarios fueron las infecciones de la herida quirúrgica, la duración de la estadía hospitalaria y la readmisión.De los 923 pacientes, el 23% (n = 213) consumían opioides antes de la operación. El grupo con opioides preoperatorios tenía más mujeres (p = 0.047), se sometió a una cirugía abierta (p = 0.003), tenía mas indicaciones no malignas (p = 0.013) y tenía una clasificación ASA más alta (p = 0.003). Aunque la mediana de la estadía hospitalaria fue más larga (4,7 días frente a 4,0; p <0,001), no hubo diferencia en ninguna infección de la herida quirúrgica (10,3% frente a 7,1%, p = 0,123) o las readmisiones (14,2% frente a 14,1%, p = 0,954). El análisis multivariable identificó que el uso de opioides preoperatorios (17.0% más larga LOS; IC 95%: 6.8%, 28.2%) y ASA 3 o 4 (27.2% más larga LOS; IC 95%: 17.1, 38.3) se asocia con un aumento en LOS.La evaluación retrospectiva poco precisa del consumo de opioides y el pequeño número de casos limitan las conclusiones sobre cualquier respuesta relacionada con la dosis - resultado.Si bien el consumo de opioides preoperatorios no se asoció con un aumento en la tasa de infecciones de la herida quirúrgica o las readmisiones, ella se asoció de forma independiente con un aumento de la LOS hospitalaria. Serán necesarias estrategias perioperatorias innovadoras para eliminar estas diferencias en los pacientes consumidores cronicos de opioides. Consulte Video Resumen en http://links.lww.com/DCR/B280.

Randomized Controlled Trial Multicenter StudyEffect of Midazolam in Addition to Propofol and Opiate Sedation on the Quality of Recovery After Colonoscopy: A Randomized Clinical Trial.
There is a concern that midazolam, when used as a component of sedation for colonoscopy, may impair cognition and prolong recovery. We aimed to identify whether midazolam produced short- and longer-term effects on multiple dimensions of recovery including cognition. ⋯ The addition of midazolam 0.04 mg·kg as adjunct to propofol and opiate sedation for elective colonoscopy did not show evidence of any significant differences in recovery in the cognitive domain of the PostopQRS, overall quality of recovery as measured by the PostopQRS, or emergence and hospital discharge times. The use of midazolam should be determined by the anesthesiologist.

Observational StudyPhysicians Prescribe More Opioid Than Needed to Treat Pain in Children After Outpatient Urological Procedures: An Observational Cohort Study.
The epidemic of nonmedical use of prescription opioids (NMUPOs) has been fueled in part by the availability of leftover, legitimately prescribed opioids. In children, outpatient urological procedures are among the most common surgeries performed, but data are lacking to guide appropriate postoperative opioid prescribing. The aim of this study was to compare the amount of prescribed opioid medication to the amount taken for acute pain after minor pediatric urological surgery and to determine the disposition of excess opioid. In addition, we explored whether distinct patient characteristics and procedure type influenced opioid prescribing and consumption. ⋯ For minor pediatric urological surgeries in young boys, a 3-day supply (18 doses) of opioid was sufficient to adequately treat acute postoperative pain in most patients. Adjusting opioid dispensing to align with consumption and better educating patients and families on opioid disposal can be used to potentially decrease availability of leftover opioids in homes and communities.
