Routine Preoperative Hemostatic Laboratory Evaluation Prior to Tonsillectomy or Adenoidectomy in Children
Routine Preoperative Hemostatic Laboratory Evaluation Prior to Tonsillectomy or Adenoidectomy in Children - a Necessity or Habitude?

Routine analysis of coagulation profile is recommended before adenoidectomy, tonsillectomy or ventilation tubes insertion in children.

A proportion of those children reveal borderline abnormal values of Partial Prothrombin Time (aPTT) or Prothrombin Time (PT) and then they are referred to a consultant hematologist for further evaluation and recommendations before surgery.

The purpose of this study is to summarize the causes of referrals in a cohort of 200 children and to assess the further laboratory analysis preformed and the results obtained.

Data from about 200 children that were evaluated for abnormal coagulation tests performed before minor surgery.

The data will include cause of referral, laboratory analysis performed and results.

If the data allows the outcome of the operation and bleeding complications, will also recorded.
