The comparison of two methods of hemostasis in bleeding during surgery of soft tissue upper limb

摘要

Background: mechanical, thermal or chemical homeostasis is required to stop bleeding during surgery.The purpose of this study is to compare two method of hemostasis in bleeding rate during surgery of soft tissuie upper limb. Materials and Methods: In this case - control study 80 patients with inclusion criteria(age under50,without abdominal trauma,BMI less than30 and without soft tissue damage)that were operated by a surgen with available sampling (regarding to inclusion criteria, age and sex ) non randomly divided into two groups of case and control and intervention in case group was base on causing hemostasis with electrocautery and tourniquet, but in control group, on electrocautery to cause homeostasis from beginning of operating tourniquet was used.Volume of lost blood was based on the number of used gases and suction was not used for any cases. Data collected by questionnaire and were analyzed by SPSS software and descriptive- analytic statistics. Results: Mean age of case group was 31.62± 8/54 years and control group was 29.9±8.05 year. There was not a significant age difference between two groups(p=0.6). 63.8% of samples were men and and 36.2% were women . Most of surgical cases was related to repairing of ruptured flexor tendons of forearm (37.5%).The least was related to cyst and foreign bodies (12.5%). Tourniquet Mean time in case and control groups were 27.87±4.3 and 29.4±6.6 respectively and mean lost blood volume in case and control group were 16.3±5.3 and 17.2±4.7 respectively but there was no significant statistical difference in two groups(p=0.1). Conclusion: Tissue necrosis is a serious complication of Electro-cautery, so it is better to limit the use of Electro-cautery in soft tissue operations. But more researches are needed to confirm these results.
