For intensive infusion therapy, a patient with acute respiratory failure underwent subclavian vein catheterization using the Seldinger technique. After administration of 600 mL of the infusion solution, the patient's condition sharply deteriorated, tachypnea increased from 26 / min. to 40 / min., tidal volume decreased from 400 ml. to 250 ml. Auscultation detects sharply weakened respiration on the right. Percussion detects a dull sound. What complication developed in this patient?

Answer options

1. Hydrothorax
2. Acute heart failure
3. Pulmonary edema
4. Pulmonary embolism
5. Cerebral edema

Explanation

Based on the provided information, the most likely complication that developed in this patient is Hydrothorax. Hydrothorax refers to the accumulation of fluid in the pleural cavity, which can occur as a complication of subclavian vein catheterization using the Seldinger technique. The Seldinger technique involves the insertion of a catheter into a blood vessel using a guidewire and dilators.The patient's condition sharply deteriorated after the administration of the infusion solution, with an increase in tachypnea (respiratory rate) from 26/min. to 40/min. and a decrease in tidal volume from 400 mL to 250 mL.These changes suggest a significant impairment in respiratory function.Auscultation detecting sharply weakened respiration on the right side, along with the dull sound detected upon percussion, indicates that there is a problem specifically on the right side of the chest. The presence of these findings, along with the sudden deterioration in respiratory function, suggests the development of hydrothorax.● Pulmonary edema typically presents with symptoms such as breathlessness, coughing, and frothy sputum. Although respiratory distress is present in this case, the specific findings of weakened respiration on the right side and dull sound on percussion point more towards hydrothorax than pulmonary edema.● Pulmonary embolism usually presents with sudden-onset dyspnea, pleuritic chest pain, and sometimes hemoptysis. The absence of these features and the presence of specific localizing signs (weakened respiration on the right side) make pulmonary embolism less likely.● Acute heart failure may cause respiratory symptoms, but the specific findings of weakened respiration on the right side and dull sound on percussion suggest a local pleural problem (hydrothorax) rather than a primary cardiac issue.● Cerebral edema is not directly related to the presented symptoms and findings, and there is no indication in the question to suggest cerebral edema as a complication.Therefore, based on the clinical presentation, the most likely complication developed in this patient is hydrothorax, which can occur as a result of subclavian vein catheterization using the Seldinger technique.
