Bioparameters in patients undergoing upper limb surgery under intercalenic brachial plexus block

Abstract

Introduction: brachial plexus block is the most used anesthetic method in surgical procedures of the upper limbs. It is probably the most studied non-neuraxial regional anesthesia technique. Objective: To evaluate the behavior of bioparameters in upper limb surgeries under interscalene brachial plexus block. Method: a quantitative, prospective, longitudinal, observational and descriptive study was carried out at the Celia Sánchez Manduley Hospital in Manzanillo between 2019 and 2023, the universe included 23 patients. Theoretical, empirical and statistical-mathematical methods were used. Results: ages between 41 and 50 years, male sex and physical status II predominated. The main comorbidities are smoking, high blood pressure and bronchial asthma. Humerus fracture and shoulder instability were the surgical pathologies that affected the patients. Heart rate, % SpO2, and systolic and diastolic blood pressure intraoperatively and postoperatively behaved with minimal alterations arising from the application of the anesthetic method. The main complications, high blood pressure, mild sinus tachycardia, recurrent laryngeal nerve block and Horner's syndrome. The values of the bioparameters according to the anesthetic agent used, behaved in normal values, with predominance of the use of lidocaine. Conclusions: the behavior of bioparameters was evaluated in patients undergoing upper limb surgery under interscalenic brachial plexus block. According to the scale used, the largest number of patients presented normal values in the results of their bioparameters.
