Evaluation about the effects of ultrasound guided infraclavicular block in upper limb surgeries with traditional methods and perfusion index [Üst Ekstremite Cerrahilerinde Ultrasonografi Eşli?inde Uygulanan İnfraklaviküler Blo?un Geleneksel Yöntemlerle ve Perfüzyon İndeksi ile De?erlendirilmesi]

Abstract

Objective: Recently, there are many researches about perfusion index which is measured by using pulse oximetry technology for evaluating the efficiency of peripheric nerve block. In this research; we aimed the evaluation between perfusion index and conventional methods about evaluating the success and efficiency of ultrasound guided infraclavicular block which was made on patients who had upper limb surgery. Material and Methods: 30 patients at the age of between 18-70 who will have a surgery of hand, forearm, arm by Orthopedics and Traumatology Department in American Society of Anesthesiologists I-II groups are taken into this research after the patient's and ethics committee's approval are taken. Our research was made as prospective. Ultrasound guided lateral sagittal infraclavicular block was applied to all patients with local anesthetic solution which was prepared as; 1 mg/kg 0.5% bupivakain+5 mg/kg 2% prilokain+NaCl 0.9% until reaching the solution limit of 45 cc. Basal values of heart rate, mean arterial pressure, peripheric oxygen saturation, perfusion index, cold sensory loss test, Pin-prick test and distal skin temperature and the values at the minutes of 5 th , 10 th , 15 th , 20 th , 25 th , 30 th are recorded. Results: When we compare the perfusion index values of the patients in research which were measured at different times, the difference was significant. When the measurements were compared as in double, differences between basal and 5 th , 10 th , 15 th , 20 th , 25 th , 30 th were significant. Time of cold sensory loss was 13.16±3.39 minutes (min 10 and max 25 minutes). Time of Pin-prick test positivity was 15.00± 4.23 minutes (min 10 and max 30 minutes). Motor block onset time was 10.66±3.40 minutes (min 5 and max 20 minutes). Conclusion: In this research; we showed that pulse-oximetry perfusion index can rapidly reveal the perfusion increase which is reasoned by sympathetic block that occurs after infraclavicular block and before sensory and motor block. It is concluded that it is a sensitive and simple method which can be used with traditional methods. Copyright © 2018 by Türkiye Klinikleri.
