MORAIS, Bruno Salomé de et al. Bilateral blockade of the pudend nerve to hemorrhoidectomy in achondroplasic patient: case report. Rev. Bras. Anestesiol. [online]. 2006, vol.56, n.2, pp.168-173. ISSN 1806-907X. http://dx.doi.org/10.1590/S0034-70942006000200008.
BACKGROUND AND OBJECTIVES: The achondroplasic dwarfism or achondroplasia is the most common form of dwarfism and occurs, in most of the cases, as a result of spontaneous genetic alteration. The anesthesia in these patients presents several particularities. The objective of the present report was to describe an achondroplasic patient case, with a previous history of surgical procedure of the vertebral column for medullar decompression, submitted to haemorrhoidectomy through the bilateral blockade of the pudend nerves. CASE REPORT: Male patient, 47 years old, achondroplasic, hospitalized to perform hemorrhoidectomy. Upon physical examination, he presented a shortened neck with limited extension of the head, Mallampati class IV, thyromental distance of 6 cm and opening of the mouth of 3.5 cm. The vertebral column presented thoracic kyphosis and severe lumbar lordosis, in addition to a surgical scar in the lumbar region. A bilateral blockade of the pudend nerves was performed with ropivacaine at 1%, via transperineal, with isolated needle measuring 0.8 mm x 100 mm 21G (Stimuplex A100 BBraun, Melsungen, Germany) connected to the peripheral nerve stimulator (Stimuplex-DIG, BBraun).The patient was positioned in ventral decubitus and the surgery started after 15 minutes of anesthetic administration. During the entire procedure, the patient remained conscious and did not report pain or discomfort. Up to the moment his hospital discharge (22 hours after the performance of the blockade), the patient did not mention pain, discomfort, nausea, vomit, motor blockade, urinary retention or incontinence. After his discharge from the hospital, he evolved well presenting evacuation after 31 hours from surgery. CONCLUSIONS: The case illustrated the use of the bilateral blockade of the pudend nerves, with the help of the neurostimulator, as an isolated anesthetic techniques for hemorrhoidectomy.
