Routine Preoperative Hemostatic Laboratory Evaluation Prior to Tonsillectomy or Adenoidectomy in Children

2014-08-27 03:19:31 | BioPortfolio


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.

Medical and Biotech [MESH] Definitions

Hemorrhagic and thrombotic disorders resulting from abnormalities or deficiencies of coagulation proteins.

Hemorrhagic and thrombotic disorders that occur as a consequence of abnormalities in blood coagulation due to a variety of factors such as COAGULATION PROTEIN DISORDERS; BLOOD PLATELET DISORDERS; BLOOD PROTEIN DISORDERS or nutritional conditions.

Hemorrhagic and thrombotic disorders that occur as a consequence of inherited abnormalities in blood coagulation.

The coagulation of tissue by an intense beam of light, including laser (LASER COAGULATION). In the eye it is used in the treatment of retinal detachments, retinal holes, aneurysms, hemorrhages, and malignant and benign neoplasms. (Dictionary of Visual Science, 3d ed)

Substances, usually endogenous, that act as inhibitors of blood coagulation. They may affect one or multiple enzymes throughout the process. As a group, they also inhibit enzymes involved in processes other than blood coagulation, such as those from the complement system, fibrinolytic enzyme system, blood cells, and bacteria.
