Impacto de la anestesia intravenosa en cirugía robótica para paciente de alto riesgo sometido a cirugía oncológica de larga duración en el Centro Médico Naval / Impact of intravenous anesthesia in robotic surgery for high-risk patient undergoing long-term oncologic surgery at the Naval Medical Center

Resumen: La práctica de cirugía robótica es un proceso complejo que implica desarrollo y tecnología no sólo en el campo de la cirugía, sino también en el campo de la anestesiología. Implica un proceso multifactorial, ya que ha generado un cambio drástico multidisciplinario basado en tecnología de punta que pretende ofrecer mejores condiciones durante el manejo perioperatorio en cirugía robótica. La anestesia total intravenosa cumple objetivos específicos en relación a la posición del paciente, relajación cerebral, neuroprotección, hemodinamia, pérdida y recuperación de la conciencia, parálisis neuromuscular, parámetros ventilatorios, etc. Ofrece seguridad y calidad al paciente durante el procedimiento con una mínima interferencia con el monitoreo electrofisiológico y permite modular la profundidad anestésica desde una neurosedación hasta una anestesia general, de acuerdo a las diferentes etapas de la cirugía. Un factor atribuible a la anestesia moderna para el éxito de la cirugía robótica es usar diferentes agentes anestésicos que promuevan inducción, mantenimiento y emersión anestésica más rápida y suave, a fin de reducir el tiempo de recuperación del estado de conciencia, funciones básicas y psicomotoras como la anestesia general multimodal.

Abstract: The practice of robotic surgery is a complex process, involving development and technology; not only in the surgery field but also in the anesthesiology field. It implies a multifactorial process since it has generated a drastic multidisciplinary change based on state-of-the-art technology; which aims to offer better conditions during perioperative management in robotic surgery. Intravenous Total Anesthesia accomplishes specific objectives in relation to patient position, brain relaxation, neuroprotection, hemodynamics, loss and recovery of consciousness, neuromuscular paralysis, ventilatory parameters, providing safety and quality during the procedure; with minimal intervention during electrophysiological monitoring and enabling anesthetic depth to be modulated from neurosedation to general anesthesia, according to the different stages of the surgery. A factor attributable to modern anesthesia for robotic surgery success is to employ different anesthetic agents promoting induction, maintenance of general anesthesia, smother and faster anesthetic emersion, for the purpose of reducing recovery time of the state of consciousness), basic and psychomotor functions; as is the general multimodal anesthesia.

[Urachus cystopexy: new technique for bladder suspension associated to the Burch's technique in the treatment of cystocele and stress urinary incontinence. Long-term follow-up]. / Uraco-cistopexia: nueva técnica de cisto-suspensión asociada al Burch para el tratamiento del cistocele e incontinencia urinaria de esfuerzo, seguimiento a largo plazo.

OBJECTIVES: To compare long term efficacy and morbidity in patients with stress urinary incontinence treated using Burch's colpopexy versus Burch's colpopexy plus urachus-cystopexy. METHODS: Retrospective, longitudinal comparative, observational study in 129 patients with stress urinary incontinence (SUI) or mixed urinary incontinence (MUI). Fifty four patients underwent Burch's colpopexy (group B) and 75 patients underwent Burch's colpopexy and urachus-cystopexy (group B U). These patients completed inclusion criteria from January 1994 to March 2005. The severity of SUI was evaluated by means of the number of pads used in 24 hours. Cure was defined as patients not using any pad for urinary leakage; improvement, when the number of pads used decreased to one pad a day; and failure when the patients used more than 1 pad in 24 hours. In MUI the urge urinary incontinence (UUI) component was evaluated separately. RESULTS: After 12 months of follow-up, 47 patients of group B and 67 patients of group BU were evaluated analyzing cure/improvement. Either one were observed in 74.4% (29/6) and 97% (58/7) respectively (p = 0.001). At 24 months follow up, in 35 patients of group B and 42 of group BU, a rate of 65.7% (22/3) and 97.6% (37/4) was observed respectively (p = 0.014). MUI was present in 53.7% of group B and 58.6% patients of group BU. An independent analysis was made on urge urinary incontinence (UUI) in these patients at 12 months; 53.1% of group B and 19.4% of group BU had UUI (p = 0.000). At 24 months, 50% of patients of group B and 26.19% of group BU had UUI (p = 0.029). De novo UUI was present in 19.4% of group B and 5.97% of group BU (p = 0.000) at 12 months follow-up, and in 17.64% of patients of group B and 13.95% of group BU (p = 0.005) at 24 months. Complications related to urachus-cystopexy presented trans-operatively: vesical injury in 3 of the initial cases, solved with bladder closure in two layers and vesical catheter for 7 days approximately. CONCLUSIONS: Burch's procedure in addition to urachus-cystopexy was better for the treatment of SUI and UUI than Burch's procedure alone in a long term clinical follow-up. Surgical fixation of the urachus to the anterior abdominal wall provides extra support to the bladder and probably reduces its displacement during strength, avoiding tension of urethral and bladder neck fixations and increasing the efficacy of Burch's procedure.

Uraco-cistopexia: nueva técnica de cisto-suspensión asociada al burch para el tratamiento del cistocele e incontinencia urinaria de esfuerzo, seguimiento a largo plazo / Urachus cystopexy: New technique for bladder suspension associated to the Burch`s technique in the treatment of cystocele and stress urinary incontinence. Long-term follow-up

OBJETIVO: Comparar la eficacia y morbilidad a largo plazo de pacientes con incontinencia urinaria de esfuerzo a las que se realizó uretro-cervico-suspensión tipo Burch versus el procedimiento de Burch más uraco-cistopexia.MÉTODOS: Se realizó un análisis de cohorte retrospectivo, longitudinal, comparativo y observacional. De enero de 1994 a marzo 2005 se incluyeron 129 pacientes con incontinencia urinaria de esfuerzo (IUE) o incontinencia urinaria mixta (IUM). Cincuenta y cuatro pacientes fueron sometidas a procedimiento de Burch (grupo B) y 75 pacientes a procedimiento de Burch asociado a uraco-cistopexia (grupo BU). La severidad de la incontinencia fue valorada mediante el número de apósitos utilizados durante 24 hrs. La cura se consideró cuando el paciente no requirió ningún dispositivo para la pérdida urinaria; la mejoría como una disminución a una toalla al día y fracaso el uso de más de 1 apósito en 24 horas. En la IUM, el componente de incontinencia urinaria de urgencia (IUU) se evaluó por separado(AU)

RESULTADOS: Se evaluaron 47 pacientes del grupo B y 67 pacientes del grupo BU; a los 12 meses de seguimiento observando una tasa cura/mejoría de la IUE del 74.4% (29/6) y 97% (58/7) respectivamente, p=0.001 y a los 24 meses de seguimiento 35 pacientes del grupo B y 42 pacientes del grupo BU observando una tasa del 65.7% (22/3) y 97.6% (37/4) respectivamente, p=0.014. La IUM basal se presentó en 53.7% de pacientes del grupo B y en 58.6% pacientes del grupo BU. Se analizó en forma aislada la parte de IUU de estas pacientes; a los 12 meses 53.1% de pacientes del grupo B y 19.4% del grupo BU presentaban IUU, p=0.000 y a los 24 meses 50% de pacientes del grupo B y 26.19% del grupo BU presentaban IUU, p=0.029. La IUU de novo se presentó en 19.14% de pacientes de grupo B y en el grupo BU 5.97%, p=.0000 y a los 24 meses en el grupo B 17.64% de pacientes y en el grupo BU 13.95% p=0.005. Las complicaciones relacionadas a la uraco-cistopexia se presentaron en el trans-operatorio y fue apertura vesical en 3 de los primeros casos que se resolvieron con cistorrafia en dos planos y sonda vesical por espacio de 7 días.CONCLUSIONES: El procedimiento de Burch asociado a la uraco-cistopexia tuvo mayor eficacia en la resolución a largo plazo de la IUE y del componente de IUU que el procedimiento de Burch aislado. La fijación quirúrgica del uraco a la aponeurosis de los rectos anteriores del abdomen mantiene firme la vejiga, lo que probablemente disminuye su desplazamiento durante los esfuerzos, evitando así la tensión en las fijaciones uretro-cervicales, elevando la eficacia del procedimiento de Burch(AU)
