Obstetric analgesia and anestesia with remifentanil in a patient with von Willebrand's disease

: A 30-year-old woman with von Willebrand's disease was admitted in labor. As epidural analgesia was ruled out due to risk of spinal hematoma, a pump for patient-controlled analgesia (PCA) was provided with boluses of remifentanil and set for intravenous infusion of 24 micrograms with a lockout time of 5 minutes. The patient reported analgesia to be satisfactory. Later, because of abnormal fetal positioning, an emergency cesarean was performed with the patient under general anesthesia with remifentanil, with propofol and succinylcholine for induction. A healthy girl was born free of respiratory depression. Von Willebrand's disease is a hemorrhagic disorder of autosomal dominant inheritance due to a quantitative or functional factor VIII deficit. Various subtypes and degrees of severity of abnormal bleeding have been described. It is the most common genetic hemostatic disorder affecting obstetric procedures, and although epidural analgesia has been used with strict hematologic monitoring, that technique carries a risk of hematoma. PCA is useful in patients for whom regional techniques are contraindicated. With adequate fetal and maternal monitoring, remifentanil in PCA is safe and more effective than other opiates for labor pain.
