ANALYSIS OF HEMATOLOGICAL PARAMETERS IN LATE PERIOD POST-TONSILLECTOMY BLEEDINGS
1Sağlık Bilimleri Üniversitesi Şanlıurfa Mehmet Akif İnan Eğitim Araştırma Hastanesi, Kulak Burun Boğaz, Şanlıurfa, Türkiye Objective: Tonsillectomy is one of the most common operations performed in otorhinolaryngology practice. Bleeding is an important complication in terms of mortality and morbidity. In order to predict postoperative bleeding, we aimed to detect patients with high risk of postoperative bleeding by performing hematological analysis.Methods: 168 patients who underwent tonsillectomy between May 2016 and May 2019 were included in the study. Patient files were reviewed retrospectively. Preoperative and postoperative hemoglobin (HGB), white blood cell (WBC), platelet (PLT), NLR and MPV values of patients with bleeding were compared with each other and with those of patients without bleeding.
Results: Bleeding occurred in 7 patients after the first 24 hours. The mean age of the patients without bleeding was 8 (4-40) years, and the mean age of the patients with bleeding was 9 (6-38) years. The mean postoperative bleeding was 6 days (5-8 days). Pre-op WBC, HGB, PLT and NLR levels of the patients with post-tonsillectomy hemorrhage were found to be statistically similar to those without bleeding after tonsillectomy compared to Bonferroni correction (p> 0.0167). MPV levels were significantly lower (p = 0.009).
Post-op HGB, PLT, NLR and MPV levels of the patients with post-tonsillectomy bleeding were found to be statistically similar with the group without bleeding after tonsillectomy compared to Bonferroni correction (p> 0.0167). significantly higher (p <0.001).
Conclusion: Preoperative MPV values of patients with post-tonsillectomy hemorrhage were statistically lower compared to preoperative MPVs of patients without bleeding. In addition, patients with bleeding after tonsillectomy had significantly increased postoperative NLO and WBC values. Careful examination of preoperative hematological data and more detailed hematologic examination of patients at risk of preoperative bleeding may reduce postoperative bleeding frequency.
