DURAN-NAH, Jaime Jesús et al. Abnormal Pre-Surgical Tests and Their Association with Tramp-Surgical Hemorrhagic Complication in Elective Surgery. Gac. Méd. Méx [online]. 2004, vol.140, n.3, pp.281-288. ISSN 2696-1288.

Main objective: To determine whether abnormal preoperative coagulation tests (PCT) are relatedto trans-surgical bleeding complication (TSBC) during elective surgical procedures. Material and methods. Adult patients, undergone some elective surgical procedure in a tertiary care medical center, in Merida, Yucatan, Mexico in whom TSBC was looked for, were selected in a non-random fashion and included. TSBC was considered when bleeding in the surgical bed was >300 ml. Prothrombin time (PT) and partial thromboplastin time (PTT) were the PCT measured and compared against TSBC. To analyze data, inferential statistics was used. Results: Eighty four males (49%) and 86 females (51%), were included. PT, PTT or both were requested to 100% of the them. PT was prolonged in 26 (15%), and PTT was prolonged in 14 (8%) patients. TSBC was documented in 30 patients (18%), although among those with and without bleeding, neither PT averages difference (P=0.76), nor PTT averages difference (P=0.83), were statistically significant. In comparing TSBC and its relationship to abnormal PCT, again neither PT nor PTT were associated with bleeding (Fisher's exact tests for each: P= 0.41 and P= 1.0, respectively). Conclusion: In this sample, abnormal PCT were not associated with TSBC.
