Background: Epidural analgesia (EA) has been more investigated during the perioperative period than in the intensive care unit (ICU) setting. Recent studies support beneficial effects for EA beyond analgesia itself. However, data on feasibility and safety are still lacking in the ICU. Our goal was to assess the feasibility and practice of EA in ICU patients.
Methods: Multicentre observational study in 3 ICUs over a 10-month period. Goals were to report the incidence of EA-related complications and EA duration. All ICU patients receiving EA were included, whether EA was initiated in the ICU or elsewhere, e.g. in the operating room. Demographics, clinical and biological data were prospectively recorded. Epidural catheter tips were sent to the microbiology laboratory for culture.
Results: One hundred and twenty-one patients were included (mean age 60 years), with mean SOFA and median SAPS II scores of 3.2 and 32, respectively. Reasons for EA initiation included trauma (14%), postoperative pain management after major surgery (42%), and pancreatitis (31%). No EA-related neurologic complication was recorded, and one case of epidural abscess is discussed. No other EA-related infectious complications were observed. Median duration of EA was 11 days. Reasons for EA discontinuation included efficient analgesia without EA (60%) and accidental catheter removal (17%). 22% of epidural catheter cultures were positive for skin flora bacteria.
Conclusion: EA seems feasible in the ICU. Its apparent safety should be further validated in larger cohorts, but these preliminary results may stimulate more interest in the assessment of potential benefits associated with EA in the ICU setting.
