Table 1 Observation indexes
Indexes | Diagnosis criteria | Significance |
|---|---|---|
Surgical site-related complications | ||
SFC | Two doctors examined the wound flap. An obvious wave motion was present. | Main index |
STH | CT or MRI shows a cystic effusion with an obvious occupying effect. The symptoms are high intracranial pressure, such as a headache, epilepsy, haemiplegia, aphasia, or consciousness disturbance. | A serious clinical event, may even lead to a brain hernia. Emergency decompression can be necessary if mannitol does not alleviate the symptoms. |
Infection | ||
Intracranial infection | (1) Fever > 38.5 °C, (2) meningeal irritation sign, (3) leukocyte count in CSF > 100/ml, (4) glucose in CSF < 2.5 mmol/L. | |
Wound infection (extradural abscess) | (1) Redness, swelling, heat, and pain in the scalp soft tissue, wound dehiscence and purulent fluid. (2) Purulent fluid was found in debridement. | |
Pulmonary infection | (1) Symptoms of pneumonia: high fever, cough, expectoration; (2) haemogram leukocyte increased; (3) inflammation visible on chest film or lung CT. | Hemiplegia, epilepsy or consciousness disorder operatively; long-term bed rest will induce falling pneumonia. |
Epidural hematoma | High-density space-occupying lesions on CT. | |
General condition | ||
Strength-better | Preoperative muscle strength vs. muscle strength 1 week postoperatively, 0 unchanged or worse, 1 better. | |
Epilepsy-better | Preoperative epileptic seizure vs epileptic seizure 1 week postoperatively, 0 unchanged or worse, 1 better. | |
T_AVG | Average temperature from the 1st to 3rd POD. | Related to infection |
T_MAX | Max temperature from the 1st to 3rd POD. | Related to infection |
Length of stay | Postoperative hospital stay = total hospital stay − preoperative hospital stay. | Related to infection |
Postoperative medicine fee | Medicine fee = total cost − high value consumables applied during operation − navigation − operation cost | Related to infection |
