[Simple Formula to Predict Residual Amount of Continuously Infused Rocuronium in the Body].

Background: When antagonism is performed using sugammadex after continuous infusion of rocuronium, if the total amount of residual rocuronium can be esti- mated prior to performing antagonism, antagonism without excess or deficiency of sugammadex will be made possible. We therefore prepared a simple formula to predict residual amount of rocuronium in the body, which can be easily applied in clinical setting, and veri- fied it using Tivatrainer©.

[Difficult airway management during emergency tracheostomy in a patient with severe rheumatoid arthritis].

We experienced difficult airway management in a 65-year-old woman with acute dyspnea due to bilateral recurrent nerve palsy suffering from severe rheumatoid arthritis for fifty years. Her cervical spine was ankylosed and could not be extended at all. Tracheostomy was planned under local anesthesia because of difficulty of endotracheal intubation, possibility of airway obstruction and laryngeal edema.

[Evaluation of the different doses of olprinone for continuous infusion after cardiopulmonary bypass for coronary artery bypass surgery].

Background: We evaluated the hemodynamic efficacy of combined cathecholamine and three different continuous infusion doses of olprinone (0.05, 0.1, 0.
