We present a 36-year-old female patient who underwent transradial cerebrovascular angiography because of acute putaminal hemorrhage. Catheter entrapment occurred with severe pain in the right upper arm proximal to the elbow. A subclavian artery angiogram by way of a transfemoral crossover catheter revealed severe vasospasm in the axillary artery distal to the branch point between it and the posterior brachial circumflex artery. Diazepam 5 mg intravenously (IV) through a peripheral catheter, lidocaine 0.5% 5 mL injected subcutaneously, and lidocaine 2% 4 mL IV isosorbide dinitrate 2 mg IV through the angiographic crossover catheter failed to relieve the pain and catheter entrapment. An ultrasound-guided supraclavicular brachial plexus block relieved both within 3 minutes. In the past, general anesthesia would have been administered.
A 72-year-old man (166 cm, 80 kg, BMI 29 kg/m 2 ) underwent removal of a left acoustic neurinoma in park-bench position. He was under a treatment for diabetes and hyperlipidemia. Four hours after taking the position, tea-colored urine appeared. His vital signs were stable without high fever, muscle rigidity, or electrolyte abnormalities, so surgery was continued. Redness in the skin of the lateral chest was noted after surgery. Rhabdomyolysis was diagnosed by the elevation of creatine phosphokinase (7,563 IU/L) , myoglobinuria (87 ng/mL) , and diffuse swelling of the right transverse abdominal and lumbar muscles on the day after surgery. Kidney dysfunction was not observed during the perioperative period. In this case, the main cause of rhabdomyolysis is long-term surgery in park-bench position. However, there are several other risks involved such as dehydration by fluid restriction and mannitol use and obesity. Attention should be paid to hypotension, dehydration, and electrolyte imbalances in addition to the particular position. Early detection and management of rhabdomyolysis is crucial.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
