Hemorrhage following coblation-assisted tonsillectomy and adenoidectomy in children

Objective To investigate the postoperative bleeding of coblation-assisted and traditional operation in children's tonsillectomy and/or adenoidectomy.Methods Data of 1597 children with tonsillitis and adenoid hypertrophy,who underwent traditional(804 cases) or coblation-assisted(793 cases) operation between January 1,2007 and December 30,2011,were reviewed.Incidence of hemorrhage,severity and location between the two groups were compared.Results Postoperative hemorrhage occurred in 25 patients with coblation assisted operation(3.2%) and 19 patients with traditional operation(2.4%)(χ2=3.34,P0.05).There was no difference in the site(χ2=0.736,P=0.085) or incidence(Z=0.392,P=0.614).Significant difference was found in the interval of hemorrhage after surgery between the two surgical techniques(χ2=9.45,P0.01).Conclusion There is no difference in the postoperative hemorrhage for coblation-assisted or traditional tonsillectomy and adenoidectomy in children.
