Ultrasound-assisted technique in urgent traumatology
Background. In the structure of traumatism, 60–65 % falls on limb injuries. Patients with limb trauma require effective analgesia already in the early hospital period. But the method of analgesia should be not only fast, but also safe and effective. This method is regional anesthesia. The objective of this study is to evaluate the effectiveness of ultrasound (US) assisted nerve block of the upper and lower extremities in emergency traumatology. Materials and methods. The prospective analysis included 60 patients, who were treated at the trauma unit of MI “Zaporizhzhia City Multidisciplinary Clinical Hospital 9” and MI “City Clinical Emergency Hospital of Zaporizhzhia” in 2016–2017. The average age of the victims was 50.1 ± 10.1 years, 59 % of subjects — women. Results. All patients underwent US-assisted identification of nerves using the ultrasound device Logiq E with standard 12 MHz linear sensor. At the study stages, hemodynamic indices, oxygen saturation of arterial blood hemoglobin were evaluated in all patients. Statistical analysis of data provided the use of descriptive statistics methods. In all statistical analysis procedures, the critical significance level of p was 0.05. Conclusions. Among patients with isolated mechanical trauma, patients with shoulder injuries over 60 years of age (62.0 %) were dominant, most of them were women (37.0 %). US-assisted nerve block does not affect the hemodynamic indicators and the respiratory rate of patients. US-assisted nerve block eliminates life-threatening complications, but does not preclude the possibility of “minor” complications (puncture of superficial vessels with the formation of subcutaneous hematoma, unintentional superior laryngeal nerve block, unintentional phrenic nerve block). The mean duration of US-assisted nerve identification and local anesthetic administration was 12.8 ± 0.2 min.
