简介：他和她之间的距离，最多不过三米。可他已足足走了五分钟。从姿态上看，他始终都在迈进；而从位置上看，他的缓慢就像阳光下的树影一般。一只大白猫甚至就把他当作了树，从窗台上蹦下，伸长雪白的脖子，缱绻地眯眼、抻腿，在他脚踝间穿来蹭去。

简介：AbstractBackground:In neurosurgery, the necessity of having a drainage tube is controversial. Subgaleal fluid collection (SFC) often occurs, especially in a craniotomy near the "parietal site" . This study aimed to reassess the benefit of using a prophylactic epidural drainage (ED) and non-watertight dura suture in a craniotomy near the parietal site.Methods:A retrospective review was conducted on 63 consecutive patients who underwent a craniotomy near the parietal site. The patients were divided into two groups according to different period. The deal group received ED and a non-watertight dura suture (drain group, DG), the control group that did not (non-drain group, NDG). Complications and patient recovery were evaluated and analysed.Results:Three patients (11.5%, 26) in DG and 20 patients (54.1%, 37) in NDG presented with SFC (p < 0.05). One patient (3.8%) in DG and three patients (8.1%) in NDG presented with subdural tensile hydrops (STH) (p > 0.05). Six developed an infection in NDG (four intracranial infections, one abscess, one pulmonary infection), while none in DG (p > 0.05) developed infection. Three (11.5%) cases in DG and one (2.7%) case in NDG had muscle strength that improved postoperatively (p > 0.05). Fifteen (57.7%) in DG and 14 (37.8%) in NDG had epileptic seizures less frequently postoperatively (p < 0.05). The average temperature (37.4 °C vs 37.6 °C, p > 0.05), the maximum temperature (37.9 °C vs 38.1 °C, p > 0.05) on 3 PODs, the postoperative hospital stay day (7.5 days vs 8.0 days, p > 0.05), and the postoperative medicine fee (¥29762.0 vs ¥28321.0, p > 0.05) were analysed.Conclusion:In patients who undergo a craniotomy near the parietal site, the prophylactic use of ED and a non-watertight dura suture helps reduce SFC, infection, and control epilepsy.
