this study was designed to assess if the use of a sterile exsanguination tourniquet (Boazul cuff) reduced blood loss from the groin and avulsion wounds during varicose vein surgery, (saphenofemoral disconnection, stripping to knee and multiple avulsions).
prospective, parallel cohort study.
thirty-eight patients undergoing primary varicose vein surgery.
the blood loss and number of avulsion wounds were recorded for each patient.
the tourniquet was used on 21 legs and there were 24 legs in the non-tourniquet group. In the tourniquet group, the median blood loss from the groin was 15 ml, (range 5-70 ml), and from the leg was 5 ml, (range 0-120 ml). The corresponding figures for the group without the tourniquet were a median of 17.5 ml, (range 5-105 ml), and a median of 95 ml, (range 10-505 ml). The mean number of avulsions in the tourniquet group was 25 (range 9-38), and in the non-tourniquet group was 15, (range 5-40). There was significantly less blood loss from the leg in the tourniquet group (p<0.0001) despite the fact that there were more avulsions in the tourniquet group (p<0.001).
use of the Boazul cuff significantly decreases the blood loss from the avulsion sites during routine varicose vein surgery, and may encourage the surgeon to perform more avulsions.
本研究旨在评估使用无菌放血止血带（博阿祖尔袖带）是否能减少静脉曲张手术（大隐静脉股静脉离断术、剥脱至膝部及多处撕裂术）期间腹股沟和撕裂伤口的出血量。
前瞻性平行队列研究。
38例接受原发性静脉曲张手术的患者。
记录每位患者的失血量和撕裂伤口数量。
21条腿使用了止血带，非止血带组有24条腿。在止血带组中，腹股沟的中位失血量为15毫升（范围5 - 70毫升），腿部为5毫升（范围0 - 120毫升）。无止血带组的相应数字分别为中位值17.5毫升（范围5 - 105毫升）和中位值95毫升（范围10 - 505毫升）。止血带组的平均撕裂数为25个（范围9 - 38个），非止血带组为15个（范围5 - 40个）。尽管止血带组的撕裂伤口更多（p<0.001），但该组腿部的失血量明显更少（p<0.0001）。
在常规静脉曲张手术中使用博阿祖尔袖带可显著减少撕裂部位的失血量，并可能促使外科医生进行更多的撕裂操作。
