Prospective randomized single-blind study of post-operative bleeding after minor oral surgery in patients with cirrhosis.

BACKGROUND/AIMS: The management of patients with cirrhosis requiring dental extractions is complicated due to an increased risk of post-operative bleeding. Topical hemostatic agents are usually required to control bleeding in these cases, as an adjunct to systemic measures of hemostasis. The aims of this randomized, prospective, single-blind clinical study are twofold. The primary aim is to compare the hemostatic efficacy of chitosan and surgicel in patients with cirrhosis after a tooth extraction, and the secondary aim is to assess the value of the current setting as a clinical model of post-operative bleeding following minor oral surgery.

MATERIAL AND METHODS

Fifty patients with cirrhosis scheduled for a tooth extraction under local anesthesia were prospectively included in the study in a randomized fashion. Patients were blinded to the treatment group they were in. The cirrhosis classification, bleeding time, trauma score, and corrected bleeding time (during post-operative reviews) were recorded. Statistical evaluations were done.

RESULTS

Study groups had an equal number of teeth extractions (40 teeth each). There were no statistically significant differences between the groups with respect to patient demographics, cirrhosis classification, trauma score, and bleeding time. No side effects were noted.

CONCLUSION

Both Celox and Surgicel are effective for controlling bleeding and are safe after a tooth extraction in patients with cirrhosis.
