Effect of Fibrin Glue on Post-Tonsillectomy Pain

Hemostatic glues in tonsillectomy: A systematic review

OBJECTIVES/HYPOTHESIS

The aim of this study was to compare use of hemostatic glues to conventional techniques of intraoperative hemostasis for tonsillectomy.

STUDY DESIGN

A systematic review of the literature and meta-analysis.

METHODS

All published prospective controlled trials that compared hemostatic glues to conventional techniques of hemostasis were identified. We performed a meta-analysis of articles comparing fibrin sealant to electrocautery, and of those comparing electrocautery to electrocautery plus fibrin hemostasis.

RESULTS

Seven studies were identified that made qualifications for review, with a total of 748 patients. Outcome measures were postoperative hemorrhage recorded by investigators, and visual analogue scores of pain for day 1, day 3, and day 10 postoperatively. Use of fibrin sealant was not associated with a reduction in hemorrhage rates following tonsillectomy when compared to electrocautery (pooled relative risk [RR] 0.315; 95% confidence intervals [CI]: 0.047-2.093, 224 patients). No statistical difference in bleeding rate was seen between electrocautery hemostasis alone, compared to electrocautery with fibrin sealant (pooled RR 1.742; 95% CI: 0.433-7.005, 108 patients). No statistically significant difference in pain was identified.

CONCLUSIONS

Pain and bleeding are significant causes of morbidity post-tonsillectomy. We conclude that there is no significant evidence to support hemostatic glues over current techniques for reducing severity of these outcomes. Consequently, we do not recommended hemostatic glues for routine use in current clinical practice. Studies were generally of low quality and inadequately powered to detect a statistical difference, even when pooled. We advocate further research to facilitate future meta-analysis.

Effect of fibrin-coated collagen fleece (TachoComb) on pain and bleeding after adenotonsillectomy in children

CONCLUSION

Even though the use of TachoComb does not decrease pain after tonsillectomy, it is safe and useful to reduce bleeding after tonsillectomy.

OBJECTIVES

Sealing the post-tonsillectomy wound would be expected to reduce pain and bleeding by decreasing the exposure of the traumatized tissue and sensory nerves. TachoComb is a powerful topical hemostatic agent. The objectives of this study were to evaluate the effect of TachoComb on reduction of pain and bleeding after tonsillectomy.

METHODS

A prospective randomized double-blind study was performed on 120 pediatric patients undergoing adenotonsillectomy. The patients were randomized into two groups: use/non-use of TachoComb. In the study group, each tonsillar bed was covered with a TachoComb strip at the end of operation. No hemostatic agents were used in the control group. After surgery, patients were monitored for pain, bleeding, oral intake, medication administration, activity, and complications using a 10-day diary.

RESULTS

In all, 110 patients returned and filled in the diary. The use of TachoComb did not decrease pain, reduce the use of analgesic drugs or speed recovery to normal everyday life. Post-surgery bleeding was not experienced by any of the TachoComb patients, but occurred in five of the control patients. The result had borderline statistical significance (p < 0.1).
