RESUMO
Myotonic dystrophy is the most common manifestation of mytonic disease. It is a systemic disease and its most serious complications after general anesthesia result from respiratory failure. We report a case of prolonged respiratory failure after general anesthesia for cesarean section in a presumed myotonic dystrophy patient. A 36-year-old parturient underwent emergency cesarean section under general anesthesia for premature rupture of the amniotic membrane with fetal distress. At the end of the operation, the recovery of respiratory muscle from paralysis was insufficient to maintain spontaneous ventilation despite the administration of reversel agents. Her TOF count was 3/4 and she was reintubated in the PACU. The patient was transferred to the ICU for proper respiratory care and her respiration fully recovered after 21 hours of conservative supportive care.
