Abstract：Objective To evaluate the application of Infusomat(R)Space Pump combined with precise filtering infusion apparatus in prevention of phlebitis caused by esmolol hydrochloride in intravenous solution. Methods 〓Totally 100 patients receiving esmolol hydrochloride in intravenous solution were assigned to the group A(n=34), group B(n=33)and group C(n=33). In group A, the Infusomat(R)Space Pump combined with precise filtering infusion apparatus was used in intravenous infusion. In group B, the Infusomat(R)Space Pump combined with normal infusion apparatus was used. In group C, the micro-injection pump combined with extension tube was used. The incidence of phlebitis, occurrence time of phlebitis and pain degree during infusion were compared among three groups. Results 〓The incidence of phlebitis was lower in the group A than that in group B and group C(P0.05). Patients in the group A had a later occurrence time of phlebitis compared with those in the group B and group C(P0.05). Patients in the group A suffered a less severity of pain during infusion compared with those in the group B and group C. Conclusion 〓By Infusomat(R)Space Pump combined with precise filtering infusion apparatus is effective to prevent phlebitis caused by esmolol hydrochloride in intravenous solution,.
