恒速镇痛泵的故障分析与排除

Troubleshooting of post-operative continuous constant-dose analgesia

目的了解临床应用中影响一次性恒速球泵镇痛效果的机械故障或其他故障以及患者出现的不良反应。方法对两院临床持续性术后镇痛3200例分为CCEA组和CCIA组进行分析。结果CCEA组中主要以硬膜外导管因素和镇痛泵流速偏差而导致患者出现不良反应和镇痛效果不理想。而CCIA组中主要以镇痛泵流速偏差和镇痛药物导致患者出现不良反应和镇痛效果不理想。结论加强硬膜外导管固定及管理,密切术后随访,适时的心理治疗,是减少术后镇痛中机械故障和患者不良反应发生率的重要手段。

Objective To investigate the mechanical and other disorders of disposable continuous constant-dose analgesia pump, as well as the side effects of pump. Methods 3 200 patients receiving post-operative continuous constant-dose analgesia were divided into 2 groups, continuous： constant-dose epidural analgesia（CCEA） group and continuous constant-dose intravenous analgesia （CCIA） group. Results The main reasons of unsatisfactory analgesia effect and side effect in CCEA group were epidural catheter disorders. The main reasons in CCIA group were infusion speed deviation of analgesia pump and analgesics respectively. Conclusion The important means tO reduce mechanical disorders and side-effects in post-operative continuous analgesia include enhancing fixation and management of epidural catheter,intensifying post-operative fellow up and psychotherapy at proper time.
