Trends in practice and safety measures of epidural analgesia: Report of a national survey.

Background: The clinical use of epidural analgesia has changed over past decades. Minimally invasive surgery and emergence of alternative analgesic techniques have led to an overall decline in its use. In addition, there is increasing awareness of the patient-specific risks for complications such as spinal haematoma and abscess. Local guidelines for management of severe neurological complications during or after epidural analgesia, ie, "epidural alert systems", have been introduced in hospitals to coordinate and potentially streamline early diagnosis and treatment. How widely such protocols have been implemented in daily practice is unknown.

Methods: We conducted a survey to analyse trends in practice, key indications, safety measures, safety reporting, and management of complications of epidural analgesia in the Netherlands. Data were gathered using a web-based questionnaire and analysed using descriptive statistics.

Results: Questionnaires from 85 of all 94 Dutch hospitals performing epidural analgesia were collected and analysed, a 90% response rate. Fifty-five percent reported a trend towards decreased use of perioperative epidural analgesia, while 68% reported increasing use of epidural analgesia for labour. Reported key indications for epidural analgesia were thoracotomy, upper abdominal laparotomy, and abdominal cancer debulking. An epidural alert system for neurological complications of epidural analgesia was available in 45% of hospitals.

Conclusions: This national audit concerning use and safety of epidural analgesia demonstrates that a minority of Dutch hospitals have procedures to manage suspected neurological complications of epidural analgesia, whereas in the remaining hospitals responsibilities and timelines for management of epidural emergencies are determined on an ad hoc basis.
