Association of the Clinical Subtype and Etiology for Delirium with the Outcome after Risperidone Monotherapy in Patients Having Cancer.

Background Delirium is the most frequent psychiatric syndrome in patients with advanced cancer, but its management is complicated by its multifactorial pathology. In this study, we investigated the association of the clinical subtypes, possible etiologies, and reversibility of delirium in patients having cancer with risperidone monotherapy. Methods This study included 16 inpatients with advanced cancer who were consecutively referred to psychiatric consultation service or palliative care team and were diagnosed with delirium by a psychiatrist.

[Case of pulmonary hemorrhage suspected to be caused by pulmonary artery catheter after cardiac surgery].

We report a case of pulmonary hemorrhage suspected to be caused by a pulmonary artery catheter (PAC) after cardiac surgery. An 80-year-old woman underwent aortic valve replacement, mitral valve replacement, and tricuspid annuloplasty. After anesthesia induction, a PAC was inserted from the right jugular vein and fixed at 48 cm, but it could not be wedged.

[Case of paroxysmal atrial fibrillation after general anesthesia caused by undiagnosed and untreated hyperthyroidism].

A 21-year-old man was scheduled to undergo posterior cruciate ligament reconstruction under arthroscopic control. The patient did not have a previous history of thyroid disease. Low blood cholesterol was revealed in the laboratory data.

[Efficacy of continuous intraoperative administration of low-dose milrinone during the circumflex artery anastomosis of off-pump coronary artery bypass].

Background: We have experienced instability of hemodynamic state during off-pump coronary artery bypass (OPCAB), especially, circumflex (Cx) artery anastomosis. Although some reports have implied the efficacy of mirlinone in OPCAB anastomosis due to its characteristic inotropic effect without increasing myocardial oxygen consumption, we examined the effect of smaller doses of mirlinone during Cx anastomosis.

Methods: Fourteen patients received milrinone (M group) continuously at a rate of 0.

[Minitracheotomy in treating upper airway obstruction after anterior cervical fusion].

Respiratory disturbance occurs sometimes after anterior cervical fusion. This is often a result of upper airway obstruction due to prevertebral soft tissue swelling. Therefore we used cricothyrotomy tubes (Mini-Trach) in two patients with postoperative upper airway obstruction and performed assist-ventilation via the tubes.
