| Outline of Final Research Achievements |
The purpose of this study was to observe the peripheral intravenous catheter failures (PIVC-CF) including extravasation during intravenous therapy, and to clarify causes and factors of PIVC-CF. Patients were observed just before catheter removal by ultrasonography. The frequency of thrombus with subcutaneous edema was significantly associated with PIVC-CF, and ‘two or more puncture attempts' was related to thrombus with subcutaneous edema.
Our findings suggested that healthcare professionals should succeed with only one puncture attempt, use a catheter which is made of polyurethanes rather than Teflon, and select the vein which has a diameter that is three times as large as the catheter's diameter. Furthermore, the rate of PIVC-CF was significantly associated with high osmolarity irritant infusate defined as osmotic pressure ratio which is greater than or equal to 3.
