Eficacia de las infiltraciones epidurales en el abordaje del dolor y la discapacidad por radiculopatía lumbosacra aguda y subaguda / Efficacy of epidural infiltration in the management of pain and disability due to acute and subacute lumbosacral radiculopathy

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)

[Establishment of a modified surgical safety checklist for the neurosurgical patient: Initial experience in 400 cases]. / Implantación de la lista de verificación quirúrgica de la Organización Mundial de la Salud modificada para el paciente neuroquirúrgico: experiencia inicial en 400 casos.

INTRODUCTION: Adverse events during diagnostic and therapeutic procedures and medical errors associated with them are an important source of patient morbidity. In an attempt to reduce these, the WHO has proposed a series of measures applicable to medical and surgical patients. Within these last ones is the surgical safety checklist (SSC), a brief questionnaire that does not increase healthcare costs, is accessible to all surgical centres and can be adapted to each specific environment. OBJECTIVES: To evaluate the effectiveness of establishing a modified WHO SSC on the safety and quality of care of the neurosurgical patient in a third-level university hospital. MATERIAL AND METHODS: The SSC was applied to a series of 400 scheduled surgeries between May 2009 and May 2010. During the initial 6 months, 183 surgical procedures were performed (group 1). All adverse events detected in this period were studied with a root-cause analysis methodology (RCA) and, according to its results, corrective measures were introduced. After that, 217 procedures were performed (group 2). RESULTS: We recorded 51 events in 44 surgeries (11%). We were able to correct 88.23% of them before surgery was initiated, avoiding any consequence in the normal management of the case. In Group 1, incidents were noted in 15.3% of the procedures. The RCA suggested that 37.8% of the events had a human cause, followed by problems related to material resources and equipment in 29.7%, and organisational reasons in 21.6%. Incidence of events was reduced in group 2 to 7.4% (P=.01). Corrective measures prevented the appearance of perioperative events in 1 out of 13 procedures. CONCLUSIONS: The SSC is an effective tool for improving safety in neurosurgical patients, which can be established in surgical departments of any hospital without increasing healthcare costs or operative time.

Introducción: Las complicaciones de los procedimientos diagnósticos y terapéuticos, así como los errores asociados a éstos, son una causa importante de morbilidad. En un intento de minimizarlos, la Organización Mundial de la Salud (OMS) ha propuesto una serie de medidas aplicables tanto a pacientes médicos como quirúrgicos. Entre estas últimas destaca la lista de verificación quirúrgica (LVQ), un breve cuestionario que, sin incrementar el gasto hospitalario, resulta accesible a todos los centros quirúrgicos y es adaptable a las necesidades de cada uno de ellos. Objetivos: Valorar la efectividad de la implantación de la LVQ de la OMS modificada en la mejora de la seguridad del paciente neuroquirúrgico y de la calidad de su atención en un hospital universitario de tercer nivel. Material y métodos: La LVQ fue aplicada a una serie de 400 cirugías programadas entre mayo de 2009 y mayo de 2010. Durante los primeros 6 meses se realizaron 183 procedimientos quirúrgicos (grupo 1). Los incidentes detectados durante este período fueron sometidos a un análisis causa-raíz (ACR), introduciéndose medidas correctoras de acuerdo con sus resultados. Doscientas diecisiete cirugías fueron realizadas en los 6 meses posteriores (grupo 2).Resultados: Aparecieron 51 incidencias que afectaron a 44 procedimientos (11%). El 88,2% de estas incidencias pudieron ser subsanadas precozmente, sin repercusión sobre la cirugía. En el grupo 1 se produjeron incidencias en el 15,3% de las intervenciones. El ACR demostró causas-raíz de origen humano en el 37,8%, problemas de equipamiento (..) (AU)

Complications of endoscopic microdiscectomy using the EASYGO! system: is there any difference with conventional discectomy during the learning-curve period?

BACKGROUND: Microendoscopic discectomy (MED) is emerging as a minimally invasive alternative to conventional microsurgical discectomy (MSD). EASYGO! is a new system for spinal endoscopy that claims smooth transition from MSD to MED, with a reduced learning curve period. The aims of this study were to describe the complications that appeared during the learning curve period of MED and to compare their incidence with the rate and type of complications that occurred during a simultaneous non-randomised series of standard MSDs. METHODS: Between July 2009 and December 2010, 138 patients underwent scheduled first-time discectomy in our institution, 37 using an MED approach and 101 by a conventional MSD. A MED learning curve was obtained by plotting every case with its respective operative time. Complications, length of hospital stay, need of further surgery and outcome were prospectively recorded in both groups. RESULTS: The mean operative time was 66 min for the MSD group and 100 min for the MED group, although for the last 14 cases of the latter group the time was reduced. Curve-fitting techniques showed that the inverse equation, ƒ(x) = 122.12/x + 73.05, had the best correlation between case number and operative time. The learning curve was overcome after the 30th case. Complications occurred in 9.8 % of the MSD group and 8.1 % of the MED group (P = 0.49). Average length of hospital stay was 2.36 days for the MED group and 3.36 days for the MSD group (P = 0.01). The procedure successfully relieved patient symptoms in 68.63 % of the MSD group and 89.92 % of the MED group. No revision surgery was required in the MED group, but it was necessary in ten patients of the MSD group. CONCLUSIONS: Between 25 and 30 cases are needed to reach the learning curve's asymptote of MED. Even during this initial learning period MED is a safe procedure, with comparable results to those obtained with conventional MSD and with a similar complication rate. The key points for reducing intraoperative complications are an adequate expertise in MSD, a precise selection of initial cases, a proper surgical planning and a careful technique, which are mandatory to avoid unnecessary neurological injury in an otherwise secure surgical approach.
