Introduction. Regional anesthesia is an important, innovative, and popular technique for anesthetic and painkiller management. In supraclavicular brachial plexus blockade, there is a 50-60% rate of diaphragmatic paralysis. Clinical presentation is variable according to the patient's internal and external factors. There are multiple radiological techniques in diagnosis, with ultrasounds being very useful due to their easy access. The objective is to determine the incidence of diaphragmatic paralysis secondary to supraclavicular brachial plexus blockade guided by ultrasound in a fourth level institution. Methodology. Prospective, longitudinal, analytical study. 110 patients were selected. Inclusion criteria: patients over 18 years of age subject to upper limb surgery with supraclavicular brachial plexus blockade. Exclusion criteria: ASA (American Society of Anesthesiologists) 4 and 5 patients, pregnant women BMI >35 kg/m2 patients with neuromuscular background, restrictive or obstructive pulmonary disease, phrenic nerve paralysis, or diaphragmatic dysfunction. An analysis was carried out via statistical tests, describing the different degrees of diaphragmatic paralysis. Results. In patients who met the inclusion criteria, the incidence of diaphragmatic paralysis was 65% (37% with total and 28% with partial paralysis), 1.81% showed respiratory symptoms without hemodynamic changes. Discussion. Supraclavicular brachial plexus blockade is a technique related to diaphragmatic paralysis. Ultrasound has allowed for the incidence of this complication to be reduced. It is a useful method in post-operative diagnosis. Conclusions. Diaphragmatic paralysis after supraclavicular brachial plexus blockade is a complication mainly observed in patients with previous pulmonary problems. Therefore, it must be strictly monitored.
