SUSTAINED PAIN RELIEF TO AVOID ANALGESIC GAPS
With regard to equipment related analgesic gaps – a study has shown that 12% of patients treated with IV PCA suffer analgesic gaps due to equipment issues. Potential equipment issues with IV PCA are, for example, infiltration, device malfunction or failure, line pulled out, leaking, obstructed or air in line and low or dead batteries.3 Furthermore, a catheter occlusion can also lead to analgesic gaps. According to a study from 2014, 25% of peripheral intravenous catheters fail due to occlusion. Small needle diameter and female gender are risk factors for occlusion.4
Approaches to help avoid or minimise analgesic gaps are, for example:
- Analgesic gaps can be minimised by maximizing efficiency or using patient-controlled analgesia.5
- Training can help reduce the likelihood of the above equipment issues and to identify and manage them when they do occur.6
