intravenous nutrition solutions have been well tolerated when the osmolality is less than 983 mmol/l but the daily risk of extravasation is 0-54 for "butterfly" needles and ofphlebitis 0 25 for short plastic catheters.' The daily risk of phlebitis with our fine silicone catheters was 0-016, with a median period of function of nine days. One patient with pancreatic abscess received 60 days of complete intravenous nutrition through a single catheter. There were no bacteraemic episodes related to the catheter, while the expected rate with central intravenous nutrition is 4%.
