OLIVEIRA, Carlos Rogério Degrandi; PARIS, Valter César; PEREIRA, Renato Augusto and LARA, Felipe Souza Thyrso de. Anesthesia in a patient with congenital insensitivity to pain and anhidrosis. Rev. Bras. Anestesiol. [online]. 2009, vol.59, n.5, pp. 602-609. ISSN 1806-907X. http://dx.doi.org/10.1590/S0034-70942009000500009.
ACKGROUND AND OBJECTIVES: Congenital insensitivity to pain and Anhidrosis (CIPA) or hereditary sensory and autonomic neuropathy type IV (HSAN IV) is a rare autosomal recessive neuropathy of the group of hereditary sensory and autonomic neuropathies (HSAN) characterized by insensitivity to pain, anhidrosis, and mental retardation. Since it is a rare condition, reports on the anesthetic conduct in patients with CIPA are not easily found in the literature. The objective of this report was to present the anesthetic conduct in a patient with CIPA undergoing left ankle arthrodesis with placement of an implant, and to discuss the characteristics of this disorder that concern anesthesiologists the most. CASE REPORT: A female patient with a history of CIPA was admitted for left ankle arthrodesis due to Charcot arthropathy. In the operating room, the patient was monitored with an electrocardiograph, bispectral index, 95% SEF, non-invasive blood pressure, and peripheral hemoglobin saturation; she was pre-medicated with midazolam and underwent intravenous anesthesia with propofol and cisatracurium. The administration of analgesics was not necessary. After tracheal intubation, monitoring of end-expiratory pressure of carbon dioxide and esophageal temperature were added. The patient did not develop postoperative complications. She was discharged from the hospital on the second postoperative day. CONCLUSIONS: Although there is insensitivity to pain, some patients present tactile hyperesthesia that can cause unpleasant feelings during surgical manipulation. Despite reports in the literature of patients undergoing neuroaxis blocks, and even procedures without anesthesia, intravenous anesthesia, which provided adequate conditions for the anesthetic-surgical procedure was used in this case.
