The routine use of a flumazenil infusion following percutaneous endoscopic gastrostomy placement to reduce early post-procedure mortality.

OBJECTIVES Percutaneous endoscopic gastrostomy (PEG) insertion offers secure enteral nutrition, but there is a significant mortality associated with the procedure. We reviewed our sedation practice and the effect of yearly protocol changes to establish if the routine reversal of midazolam with a flumazenil infusion improved mortality. METHODS Since 2003 yearly protocol changes have been introduced, including pre-assessment and sedation reversal. We retrospectively audited one-week and one-month mortality and aspiration rates. RESULTS The average one-week mortality rate was 9.2%. The pooled death rates within the first week for patients prior to routine sedation reversal (n=522) was 10.7% and for patients who received routine reversal (n=144) was 5.4% (p=0.087). Within the first month, death rates were 26.3% prior to reversal and 21.4% in the sedation reversal group (p=0.30). CONCLUSIONS The routine use of flumazenil infusion in appropriate patients is safe. Flumazenil infusion may have a role to play in selected patients at highest risk of aspiration. A prospective, randomised study is warranted.
