1. BackgroundBackground Accidental disconnection of an indwelling epidural catheter from the filter is not uncommon There is no quoted incidence rate in the literature Usually this leads to the disconnected catheter lying on the patient’s skin, clothing or bedclothes, exposing the patient to potential risk of infection The anaesthetist is then faced with the decision whether to remove the catheter completely and reinserting it if necessary or cutting &/or cleaning the end of the catheter & reconnect To date, the 2004 guideline on good practice 1 (revised to best practice in 2010 2 ) advises that local protocols & guidelines should include the management of accidental catheter disconnection (recommendation 8.4) but it only states that “the decision to remove or keep the epidural must be made by the anaesthetist who will take into account all risks and benefits to the patient” Management of Epidural Catheter Disconnection in the North Western Deanery, UK Ekambaram R*, Lie J† & Brocklehurst I‡ * Specialty Trainee (ST6), Lancashire Teaching Hospitals NHS Foundation Trust † Specialty Trainee (ST7), Pennine Acute Hospitals NHS Trust, UK ‡ Consultant, Pennine Acute Hospitals NHS Trust, UK Aims To gain an insight on how anaesthetists in the North Western Deanery manage epidural catheter disconnection in obstetric & non-obstetric settings To explore the rationale behind current evidence To provide recommendations on its management Methods A survey was sent via email to all practicing anaesthetists and pain nurses in the North Western Deanery using Google form Nov ’11 to 2 ’12 & June ’13 to Sept ’13 (2 phases) Responders were asked questions on management of epidural disconnection (between catheter and connector) in situations when witnessed or not, time limits, in obstetric patients and difficult epidurals and local trust policy awareness Results Total of 132 responses: 128 anaesthetists & 4 pain nurses 44% being consultants Reconnecting epidural (time limited): 20% never reconnect 37% reconnect if <30mins 12% reconnect even if >30mins 34% said other (antiseptic clean, cut & reconnect) (depends if contamination occurred) If epidural insertion was difficult, would you change the management? 21% would reconnect instead of removing 38% would not change management 46% said other (depend on clinical situation) (consider risk vs benefit) Discussion If not witnessed, 44% would abandon and either reinsert a new epidural or change to a different regime 19% would only reconnect if immediately witnessed and 42% would reconnect within 30 minutes Most indicated their management would not change for obstetric patients or those with difficult epidurals Awareness of local trust policy is poor Personal experience, influences what individual practice. There is lack of scientific evidence and recommendation for common practice Conclusion This is clearly a grey topic with huge variation of management strategies In-vitro study showed that as long as fluid was static, no bacteria was detected > 13 inches from end of catheter after 8hrs from deliberate exposure of tips to pathogens 3 Recent evidence indicating the cutting of 12cm of epidural catheter is enough to minimise infection risk 4 could play a huge role in removing good working epidurals unnecessarily &exposing patients to risks of another epidural, especially those on thromboprophylaxis 5 References 1.
