Primary tracheal cancer is extremely rare, but critical tracheal stenosis is seen in many cases. Although laser resection or stent placement is performed under general anesthesia, anesthetic management for tracheal tumor is extremely difficult in terms of airway management. We report a 65-year-old woman scheduled to undergo bronchoscopic laser surgery and insertion of Dumon stent for tracheal tumor which severely obstructed the upper airway. ⋯ Although desaturation due to unsuccessful venous drainage and difficult ventilation by laryngeal edema during the operation and tracheal obstruction by a clot after the operation was observed, the patient's clinical condition improved. In cases of severe tracheal stenosis, airway obstruction by hemorrhage, secretion and laryngeal edema, etc. occur easily. Therefore, some kind of measures should be taken for the operation and a number of precautions must be taken during the perioperative period.

Two patients with myasthenia gravis were scheduled for surgery. Anesthesia was managed with remifentanil and propofol target-controlled infusion without the use of muscle relaxants. ⋯ Throughout the surgery, muscle relaxants were not required. Thus, the use of these drugs for inducing anesthesia provided good conditions for tracheal intubation and surgery, and it precluded the need for muscle relaxants.

We report a case of spinal myoclonus following cesarean section. The patient was a 34-year-old woman without history of neurologic disorders. In the operating room, after placement of an epidural catheter at T12-L1, bupivacaine 2.4 ml was administered intrathecally via a 25 G needle at L2-3. ⋯ The patient complained of involuntary jerky movements of her lower legs 195 min after the start of the spinal anesthesia. The sensory level was T12 and she could move her legs on command but could not stop her involuntary movements. The myoclonic movements ceased 150 min later without medication and did not reappear, despite restarting the epidural anesthesia with ropivacaine.

The GlideScope video laryngoscope (Verathon Inc. Bothell, Washington, USA) is a relatively new device for tracheal intubation, which provides a excellent glottic visualization. We here report the clinical experience of the GlideScope (small) in 50 pediatric patients. ⋯ GlideScope seemed to be a novel device in pediatric patients. Further studies are required to evaluate the usefulness in neonates, small infants and children with a difficult airway.

A 34-year-old woman who was 25 weeks pregnant showed neurological symptoms of bitemporal hemianopsia and vision loss on the left side. MRI study revealed a pituitary tumor requiring surgical removal. We planned cesarean section after 32 weeks of pregnancy and removal of pituitary tumor after the improvement of general conditions of the paturient following cersarean section. ⋯ Therefore, we decided to perform the cesarean section at 30 weeks and 3 days of pregnancy and simultaneous surgical removal of the pituitary tumor. As soon as cesarean section was successfully performed with epidural anesthesia, the pituitary tumor was removed trans-sphenoidally under general anesthesia. Postoperative conditions of the mother and newborn were good and neurological symptoms of the mother improved markedly.
