Introduction General anesthesia is frequently employed in neck surgery procedures. However, in patients at high risk for general anesthesia, regional anesthesia options, such as the superficial cervical plexus block, warrant careful consideration. Patients with mediastinal lymph node enlargement face an elevated risk of airway obstruction and hemodynamic mediastinal instability during anesthesia induc-tion. In selected neck surgeries, including thyroglossal cyst excision, thyroglossal fistula repair, bronchial cyst removal, thyroidectomy, and lymph node excision, the superficial cervical plexus block presents a viable and secure alternative to general anesthesia. Case report This report details the case of a patient with mediastinal lymphadenopathy and multiple brain metastases who underwent cervical lymph node excision. Given the patient’s severe comorbidi-ties, pronounced risk of complete distal airway obstruction, hemodynamic instability, and the potential for compression effects from mediastinal mass, a superficial cervical block was administered. This block facilitated effective perioperative analgesia without inducing respiratory or cardiovascular instability. Conclusion The superficial cervical plexus block emerges as a prudent alternative to general anesthesia in high-risk patients requiring cervical lymph node excision procedures. Its utilization should be considered in such cases to enhance patient safety and perioperative management. © 2023, Serbia Medical Society. All rights reserved.

Background: Cardiac surgery-associated acute kidney injury (CSA-AKI) is the most common clinically important complication in adult patients undergoing open-heart surgery, with an incidence between 8.9% and 39%. Studies have shown that even a slight increase in serum creatinine levels after cardiac surgery significantly affects the mortality and morbidity of these patients. Aim: This study sought to determine the predictors and incidence of acute kidney injury (AKI) in patients older than 70 years undergoing elective valvular surgery. Methods: Prospective study included 156 patients scheduled for elective cardiac surgery requiring cardiopulmonary bypass (CPB) at Dedinje Cardiovascular Institute between January and September 2019. Isolated valvular surgery was performed in 87 patients, while the remaining 69 patients underwent combined coronary and valvular surgery. The development and stage of CSA-AKI were diagnosed, according to Kidney Disease Improving Global Outcome (KDIGO) criteria. Predictors and incidence of CSA-AKI development were assessed using univariate binary logistic regression analysis. Results: The incidence of CSA-AKI was 17.3%. CSA-AKI stage 1 was diagnosed in 25 patients (16.02%). CSA-AKI stage 2 was noted in one patient (0.64%), as well as stage 3 (0.64%). In six patients (3.85%), renal replacement therapy (RRT) was required. Using univariate binary logistic analysis, the following parameters were identified as predictors for CSA-AKI development: duration of cardiopulmonary bypass (OR 1.01; CI 95% (1.01-1.02); P = .002), duration of aortic clamping (OR 1.02; CI 95% (1.01-1.03); P = .002), lactate levels during the intensive care unit (ICU) stay (OR 1.33; CI 95% (1.04-1.70); P = .026), duration of mechanical ventilation (MV) (OR 1.03; CI 95% (1.1-1.07); P = .014), the use of inotropic drugs (adrenaline, dobutamine) (OR 0.38: CI 95% (0.16-0.9); P = .026; and OR 0.23; CI 95% (0.1-0.56); P = .0019, respectively), and the use of diuretics (OR 0.24; CI95% (0.06-095); P = .041). Using Mann-Whitney U test for independent samples show that the group of patients who developed CSA-AKI had significantly longer duration of hospitalization (Z = -2.751); P = .006), prolonged ICU stay (Z = -4.160; P < .001), and need for prolonged mechanical ventilation (Z = -4.411; P < .001). Conclusion: Independent predictors for AKI development after valvular surgery in patients older than 70 years are prolonged mechanical ventilation and increased lactate values, while the use of diuretics after surgery reduces the incidence of AKI. Also, the development of CSA-AKI is associated with prolonged ICU stay and a longer duration of hospitalization. © 2022 Forum Multimedia Publishing, LLC.
