Randomized Controlled TrialEpidural anesthesia using a 0,75% ropivacaine and subarachnoid anesthesia with a 0,5% bupivacaine associated or not with clonidine in hemorrhoidectomies.
To study the safety and efficiency of two anesthetic blockages in hemorrhoidectomy and the effect of clonidine on analgesia. ⋯ The subarachnoid anesthesia with a 0,5% bupivacaine with clonidine, showed better analgesia comparing with the peridural anesthesia with a 0,75% ropivacaine with or without clonidine, however all were safe and efficient. The clonidine aided on the decreasing of pain when subarachnoid anesthesia was used.
