We successfully anesthetized a 14-year-old boy with myotonic dystrophy for orthopedic surgery using sevoflurane. Sevoflurane enabled anesthetic induction and tracheal intubation without intravenous anesthetics and muscle relaxants. ⋯ The patient showed rapid anesthetic recovery and adequate spontaneous breathing. We conclude that sevoflurane is a useful anesthetic for patients with myotonic dystrophy.

We report perinatal and perianesthetic management of a female infant with sacrococcygeal teratoma who underwent fetal bladder puncture and postnatal tumor resection. At 33 weeks' gestation, fetal ultrasonography revealed an intrapelvic mass, oligohydramnios and the dilatation of the bladder. At 34 weeks' gestation, bladder puncture was performed in utero to relieve urinary obstruction by the mass. ⋯ In previous reports, several mortalities due to exsanguinating hemorrhage during surgery have been reported. In addition, sacrococcygeal teratoma is occasionally accompanied by coagulopathy and high output cardiac failure caused by arteriovenous fistulae. Therefore it is important for good patient outcomes to evaluate preoperatively the risks mentioned above.

We studied the spread of spinal anesthesia with 3 different hyperbaric solutions commercially available in Japan. Percamin-S [0.3% dibucaine in 5% hyperbaric saline] (P), Neo-Percamin. S [0.24% dibucaine with 0.12% T-caine in 9.5% glucose] (N) and 0.5% Tetcaine [tetracaine] in 10% glucose (T) were studied. ⋯ Both N and T produced significantly higher spread of analgesia than P at any of L 3-4 and L 4-5 interspaces. P and N have the same specific gravity, even though significant differences were found in spread of segmental analgesia. Local anesthesic agents and solvent solutions themselves are considered to influence the spread of spinal anesthesia as the specific gravity of hyperbaric solution does.
