ABSTRACT

Postoperative pain activates the autonomic nervous system. Sometimes it is an indirect cause of deleterious effects in several organs in the body. The use of an effective analgesia can improve the fact to discharge a patient who has been in surgery. Objective. We tried to provide the advantage of the use of preventive analgesia in peridural block alone in comparation with peridural block added with local infiltration in radical mastectomy with general anesthesia. Material and methods. This is a prospective, longitudinal and aleatory study. We included women from 20-60 years, ASA II who had been scheduled for radical mastectomy surgery and patients who had coagulation disturbs were excluded. We were using three different anesthetic procedures (AGB) general anesthesia, (AGB+BP) general anesthesia with peridural block and (AGB+BP+LI) general anesthesia with peridural infiltration and local infiltration previously to surgery. Each group was evaluated by analogue visual score (EVA) when they arrived to PACU at 15, 30, 60 and 90 minutes after surgery; we gave analgesic medication with ketorolac when EVA scores were the same or more than 5; and we measure this time, after this we reevaluated EVA score at 15 minutes (EVA 15'). Results. Group AGB required analgesic medication at 33.5 minutes, they had an EVA 15' of 5.31. Group AGB+BP required analgesic medication at 27.35 minutes, they had an EVA 15' of 3.82. Group AGB+BP+LI required analgesic medication 67.5 minutes with EVA 15' of 2.75 (p < 0.001). Conclusion. Combined anesthesia with local infiltration may prevent the apparition of pathologic postoperative pain when it decrease the central and peripherical sensibility determined as consequence to a better response to the usage of analgesics.
