ABSTRACT

Objetivo: En la cirugía del cáncer de mama, en más del 50% de las pacientes con mastectomía y/o linfadenectomía persiste el dolor en el primer año. Nuestro objetivo fue determinar la asociación entre la técnica anestésica, la intensidad del dolor agudo postquirúrgico y el desarrollo del dolor crónico postquirúrgico. Pacientes y métodos: Cuarenta pacientes fueron asignadas aleatoriamente a recibir anestesia general o anestesia general con bloqueo paravertebral para mastectomía radical modificada. Se midió el dolor mediante escala visual analógica a los 60 minutos, a las 24 horas y a los 4-5 meses se realizó encuesta de dolor crónico postquirúrgico. Resultados: No hubo diferencias significativas respecto al dolor agudo. Veintinueve pacientes contestaron a la encuesta telefónica. En el grupo del bloqueo paravertebral sólo hubo un caso de dolor neuropático y ninguno de miembro fantasma mientras que en el grupo de anestesia general hubo 7 casos de dolor neuropático asociados a 3 casos de miembro fantasma [6,7% frente a 50%; test exacto de Fischer, p = 0,01, con un RR de 7,5 (IC95% 1,0-53,5)]. Hubo dolor miofascial (contracturas en cuello) en ambos grupos sin diferencias significativas. Conclusiones: A los 4-5 meses de la cirugía la anestesia general con bloqueo paravertebral preincisional presenta menos casos de dolor crónico que sí se utiliza anestesia general y analgesia con cloruro mórfico(AU)


Background and objective: Over 50% of patients still experience pain a year after mastectomy with or without lymphadenectomy. We aimed to determine the association between anesthetic technique, acute postoperative pain intensity, and the development of chronic postoperative pain. Patients and methods: Forty patients were randomly assigned to receive general anesthesia with or without a paravertebral nerve block for modified radical mastectomy. Postoperative pain was assessed on a visual analog scale at 60 minutes and 24 hours; the patients were also asked to respond to a telephone questionnaire on chronic pain 4 to 5 months later. Results: No significant differences in acute pain were observed. Twenty-nine responded to the telephone questionnaire. Only 1 patient in the paravertebral block group reported chronic neuropathic pain and none had phantom breast pain. Only 1 patient (6.7%) in the paravertebral block group reported chronic neuropathic pain and none had phantom breast pain. In the group that received general anesthesia alone, 1 patient reported phantom breast pain and 6 patients had neuropathic pain, associated with phantom breast pain in 2 cases (incidence of chronic pain 50%; P = .01, Fischer exact test; relative risk, 7.5, 95% confidence interval, 1.0-53.5). The incidences of myofascial pain (neck muscle tightness) were similar in the 2 groups. Conclusions: Four to 5 months after mastectomy, fewer cases of chronic pain developed in the group operated under general anesthesia with a preincisional paravertebral block than in the group that received only general anesthesia, with postoperative morphine chloride for analgesia(AU)
