Temporary quadriplegia (first report) due tomisplaced catheter in an elderly patient: casereport

A 76-year-old man developed temporary quadriplegiaduring treatment with ropivacaine due to a misplacedcatheter.

The American Society of Anesthesiologists (ASA) physicalstatus 2 man, who had a history of hypertension, asbestosexposure and radical left nephrectomy, underwent aculminectomy for tumour ablation under generalanaesthesia. A thoracic paravertebral block catheter wasinserted at the end of his surgery. After sodium chloridewas injected through the catheter, negative aspiration wasconfirmed. A continuous infusion of 0.2% ropivacaine(2 mg/mL) was started with a flow of 7 mL/hr through thecatheter. Ninety minutes later, he reported paralysis in allfour limbs. He had received 21mg of ropivacaine (10.5mL).

Neurologic examination confirmed paralysis of his lowerand upper intercostal muscles and complete immobility ofhis arms and legs. He also had loss of cold sensation up toC7. His chest X-ray was consistent with intrathecal catheterlocalisation, and his CT scan was confirmatory. He wasdiagnosed with a misplaced catheter, and his localanaesthetic perfusion was discontinued immediately.Four hours after catheter removal, his quadriplegiaresolved completely. He was discharged with noneurologic sequelae.
