Abstract:
Objective To investigate the factors related to the heating effect by transarterial catheter hyperthermic infusion with the evaluation of the feasibility in controlling the tumor temperature.Methods Infusing 55-68℃ liquid at the speed of 10-40 ml/min through 6F,5F or 3F catheter with different length respectively under the similar clinical condition.The liquid temperature at the terminal exit of the catheter was measured with a digital thermometer.The factors related to the liquid temperature at the exit of the catheter were analyzed by multiple regression analysis. Results The infusion temperature,rate and the catheter length were the main related factors to the liquid temperature at the exit of the catheter as the condition similar in clinical use.When 60-65℃ liquid was infused at the rate of 20-40 ml/min through 5F catheter with length of 80 cm,the mean and 95% confidencial interval of the liquid temperature at the chetheter exit were(47.55?0.44)℃ and 44.61-48.49℃ respectively.Conclusions The liquid temperature at the exit of infusion catheter can be regulated and controlled through adjusting the liquid perfusion temperature and speed.
