Further study details as provided by Kaiser Permanente:

Primary Outcome Measures:
  • Intraoperative: Procedure time, hemostasis time, difficulty of hemostasis, blood loss [ Time Frame: intraoperative period ]
  • Postoperative: Amount of pain medication required (day 1-14), subjective pain score, postoperative day # for returning to a normal diet and normal activity [ Time Frame: postoperative period ]

Enrollment: 0
Study Start Date: July 2009
Detailed Description:

Blood loss and postoperative morbidity following adenotonsillectomy in children can be significant. The current technique for performing a tonsillectomy is "cold steel tonsillectomy" with electocautery hemostasis and a newer technique of coblation tonsillectomy. Postoperative pain has been shown to be increased in patients undergoing extensive electrocautery, with less pain seen in patients undergoing coblation tonsillectomy. The purpose of the study is to evaluate the clinical efficacy and complications of Floseal matrix hemostatic sealant for use in patients undergoing adenotonsillectomy compared with two other currently used techniques.

The study is a prospective, controlled clinical trial comparing Floseal hemostasis in "cold steel" knife dissection tonsillectomy with cautery hemostasis in "cold steel" knife dissection tonsillectomy and coblation tonsillectomy in a pediatric population. All children under the age of 18 without previous documented coagulopathy scheduled to undergo tonsillectomy will be offered enrollment in the study. Informed consent will be obtained from the patient's legal guardian. The goal of this study is to determine if Floseal reduces intraoperative blood loss, time to hemostasis, and postoperative morbidity in patients undergoing tonsillectomy compared with two other commonly used methods. Also, we wish to evaluate the complication rates following Floseal administration compared to those of electrocautery and coblation.
