The effects of clinical application of the wireless analgesic pump and its management system

Abstract

Objective To assess the safety and efficacy of the wireless analgesic pump system. Methods 144 patients (ASAI-Ⅱ), receiving postoperative patient-controlled vein analgesia (PCIA) for 48 h, were randomly divided into two groups: the test group (n=72), using the wireless analgesic pumps system, and the control group(n=72), using type ZZB analgesic pump. The settings were as follows: loading dose 5 ml, background infusion 2.5 ml/h, bolus 3 ml, lockout time 8 min, and the prescription were as follows:fentanyl 12 ug·kg-1·d-1, droperido1 5 mg admixed with NS to reach 150 ml. Outcome variables: ① Age, weight, sex, and preoperative T, Hr, RR, BP, ② pain rating NRS when using PCIA for 4, 24, 48 h, ③ the number of all attempts, ④ the number of successful delivery, ⑤ Shivering, fever, nausea, vomiting, respiratory depression and other adverse effects in first 4 h. Results 144 patients underwent thoracic, urology, orthopedics, and general surgery. No difference in age, weight, sex, and preoperative T, Hr, RR, BP were found between two groups (P＞0.05). The pain rating NRS are 1.3±1.4, 1.6±1.5 and 1.3±1.4 in test group and 1.3±1.3, 2.1±1.8 and 1.7±1.7 in control group at 4, 24,48 h. There was no difference between two groups (P＞0.05). The number of all attempts is 6±10 in test group and 5±13 in control group; the number of successful delivery is 2±4 in test group and 3±6 in control group during 48 h,which were no difference between two groups (P＞0.05). Patients did not have any adverse effect in early phase. Conclusion The wireless analgesic pump and its management system were safe for individual treating a variety of acute or chronic pain and other treatment requiring continuing or intermittent injection to maintain a certain plasma concentration.
