ABSTRACT
ABSTRACT OBJECTIVES: To evaluate bleeding and the estimated blood loss in patients who underwent total knee replacement (TKR) with different closed suction drains (3.2-mm and 4.8-mm gauge). METHODS: This was a randomized controlled trial with 22 patients who underwent TKR and were divided into two groups: Group I, with 11 patients in whom the 3.2-mm suction drain was used, and Group II, with 11 patients in whom the 4.8-mm suction drain was used. The hematocrit was measured after 24, 48 and 72 h after surgery in order to calculate the estimated blood loss. The drained volume was measured 3, 6, 12, 24, and 48 h after TKR, and thereafter both groups were compared. RESULTS: Regarding the hematocrit, there were no differences between groups in measured periods (24, 48, and 72 h after surgery). The total bleeding measured at the suction drains within 48 h was higher in Group II, with a statistically significant difference (p = 0.005); in the first 24 h, there was major bleeding in Group II (mean 893 mL), with a significant difference (p = 0.004). Between 24 and 48 h, there was no statistically significant difference in both groups (p = 0.710). The total estimated bleeding was higher in Group I, with mean of 463 mL, versus 409 mL in Group II, with no statistical significance (p = 0.394). CONCLUSIONS: Bleeding was higher in the group that used the 4.8 mm gauge suction drain, with no differences in hematocrit and estimated blood loss.
RESUMO
RESUMO OBJETIVOS: Avaliar o sangramento através do dreno suctor (DS) e a perda sanguínea estimada em pacientes submetidos à artroplastia total do joelho (ATJ) com DS de diferentes calibres (3,2 mm e 4,8 mm). MÉTODOS: Ensaio clínico randomizado com 22 pacientes submetidos à ATJ, divididos em dois grupos; no grupo I, os pacientes recebiam o DS 3,2 mm e no Grupo II, o DS 4,8 mm. O hematócrito foi aferido 24, 48 e 72 horas após a cirurgia, a fim de calcular a perda sanguínea estimada. O débito do dreno foi medido 3, 6, 12, 24 e 48 horas após a ATJ e os dois grupos foram comparados. RESULTADOS: Em relação ao hematócrito, não se observaram diferenças estatisticamente significativas entre os grupos nos períodos aferidos (24, 48 e 72 horas pós-operatória). O sangramento total medido no DS nas 48 horas foi maior no grupo II, com diferença estatisticamente significativa (p = 0,005); nas primeiras 24 horas, houve maior sangramento no grupo II (média 893 mL), com diferença significativa (p = 0,004). Entre 24 e 48 horas, não foram observadas diferenças estatisticamente significativas em ambos os grupos (p = 0,710). O sangramento total estimado foi maior no Grupo I, com média de 463 mL, enquanto no Grupo II esse valor foi de 409 mL, sem significância estatística (p = 0,394). CONCLUSÕES: O sangramento foi maior no grupo que usou DS 4,8 mm, sem diferenças no hematócrito e na perda sanguínea estimada.
