General anesthesia involving intubation or supraglottic airway device insertion

popliteal sciatic nerve block

General anesthesia is induced with propofol (0.5-2mg / kg), remifentanil (4-8㎍ / kg / hr) and rocuronium (0.4 ~ 0.6 mg / kg) involving laryngeal mask(supraglottic airway device) insertion or endotracheal intubation. Anesthesia is maintained with 1.0-2.5% sevoflurane and remifentanil.

2. A new requirement for dialysis postoperatively.

Indicate if the patient experienced pneumonia in the postoperative period. Pneumonia is defined as meeting three of five characteristics: fever, leucocytosis, CXR with infiltrate, positive culture from sputum, or treatment with antibiotics.
