Radial artery is frequently chosen for cannulation. Although the method is safe and simple, it can infrequently lead to tissue necrosis. This is a report of one case of amputation due to thumb necrosis developed from the radial artery cannulation in a patient who had open heart surgery. This is a 65 years old female who received a graft interposition of ascending aorta due to dissecting aortic aneurysm. Left radial artery cannulation was carried out after modified Allen's test appeared to be positive. On the 11 th postoperative days, we found that the catheter of left hand was obstructed, and we removed the catheter. On the 9 hrs after removal of catheter, thumb of left hand became color change and edematous with blister. On the 14 th days after removal of catheter, thumb of left hand became worsened to dusky purple to dark color change and pulseless, coldness. On the 20 th days after removal of catheter, amputation of thumb of left hand was performed.

AbstractAbstract PDF
BACKGOUND: The purpose of this study was to evaluate characteristics and mortality rates of patients admitted to the post-anesthesia care unit (PACU) for obtaining the better clinical guidances and more advanced therapeutic plan in the future.
METHODS
The medical records of total 425 patients admitted to the PACU from January to December 1998 were reviewed and analyzed according to age, sex, department, duration of stay, mechanical ventilator care, and mortality rates.
RESULTS
Patients admitted PACU were 6% of total anesthesia patients. The ratio of male to female was 1.5:1. Patients of manhood aged from 45 to 64 were 37%, pediatric patients under 15 year-old were 23%. and elderly patients over 64 year-old were 18% of total PACU patients. The ratio of patients with ventilatory support was 42%. Mortality rate of neonate under 1 month of age was about 47%. Total mortality rate was 12%.
CONCLUSIONS
To improve the outcome of the patients in PACU, continuous nutritional and medical support, cardiovascular and pulmonary monitoring, appropriate nursing care, and availability of medical staff were needed.
