Resumen
Objetivo

Identificar factores o marcadores pre o intraoperatorios que podrian indicar un riesgo mayor de hemorragia post-amigdalectomia (HPA) en ninos operados mediante electrodiseccion.

Ámbito

Hospital de primer nivel. Diseño: Estudio retrospectivo de una cohorte de 163 ninos amigdalectomizados, comparandose 7 casos de HPA frente a 156 amigdalectomizados sin HPA.

Individuos

Ninos menores de 18 anos amigdalectomizados mediante electrodiseccion entre 1997 y 2000 fueron incluidos en el estudio.

Principales medidas de resultados

edad, sexo, talla, peso, indice de masa corporal, hemoglobina, hematocrito, plaquetas, tiempo parcial de tromboplastina activada (TPTA), actividad de protrombina, fibrinogeno, ASA (clasificacion del estado fisico segun la Sociedad Americana de Anestesiologia) y tecnica hemostatica.

Resultados

La prevalencia de HPA fue del 4,29%. El riesgo de HPA en ninos intervenidos mediante electrodiseccion se encuentra incrementado significativamente en aquellos edad superior a 15 anos (OR= 8,46, p= 0,05) y si la hemostasia precisa ligaduras (OR= 8,62, p= 0,02). El TPTA ≥ 32 s resulta marginalmente significativo (OR= 7,82, p =0,05).

Conclusiones

La amigdalectomia mediante electrodiseccion presenta mayor riesgo de sangrado en los ninos mayores y si se emplean ligaduras hemostaticas.

Abstract
Objetivo

To identify pre or intraoperative risk factors that could indicate a higher risk for post-tonsillectomy hemorrhage (PTH) in children undergoing electrocautery dissection.

Set-up

Primary referral hospital.

Design

A retrospective study of 163 post-tonsillectomy children comparing 7 cases of PTH with 156 cases with no PTH.

Sample

This study includes children under the age of 18 that underwent tonsillectomy by dissection between 1997 and 2000.

Outcome parameters

Age, sex, height, weight, body mass index, hemoglobin level, hematocrit, platelet count activated partial thromboplastin time (APTT), fibrinogen, ASA index (physical state classification of the American Society of Anesthesiology) and type of hemostasis.

Results

Prevalence of PTH was 4.29% in the cohort sample. The risk of PTH in children following tonsillectomy by electrodissection is significantly increased in patients over 15 years of age (OR = 8.46, p=0.04) and when ligatures are used for hemostasis (OR= 8.62, p= 0.02). Activated partial thromboplastin time ≥ 32 seconds is marginally significant (OR= 7.82, p= 0.05).

Conclusions

Our findings show that tonsillectomy by electrodissection has an increased risk of bleeding in older children and when ligatures are used for hemostasis.
