摘要

Objective

The optimal timing of surgical intervention for chronic subdural hematomas (CSDH), specifically night-time versus daytime, remains a subject of debate, with concerns about the potential impact of circadian timing on surgical outcomes. This study evaluated the association between the timing of burr-hole drainage for CSDH and postoperative outcomes, comparing night-time and daytime surgeries.

Methods

In a post-hoc analysis of the FINISH trial, we included adult patients with symptomatic unilateral or bilateral CSDH who underwent burr-hole drainage between January 2020 and August 2022. Night-time surgery was defined as procedures starting between 23:00 and 06:00, with daytime surgeries occurring between 06:01 and 22:59. The primary outcome was functional outcome at six months post-surgery, assessed using the modified Rankin Scale (mRS), with favorable outcomes defined as an mRS of 0–3. Secondary outcomes included mortality, reoperation rates, and adverse events within six months.

Results

Our analysis of 589 patients (83% daytime surgery, 17% night-time surgery) revealed no significant differences in baseline characteristics. The unadjusted analysis suggested a higher rate of favorable functional outcomes in the night-time surgery group than in the daytime group (94% vs. 86%, p = 0.037). Mortality, adverse events, and reoperation rates were similar in the groups. Adjusted logistic regression analyses, accounting for potential confounders, indicated that night-time surgery was not associated with a higher risk of unfavorable functional outcomes compared to daytime surgery.

Conclusions

Our findings suggest that night-time surgery versus daytime surgery is not associated with worse postoperative outcomes. These findings challenges the traditional preference for daytime CSDH surgery and emphasizes the potential for flexibility in surgical scheduling to optimize patient care in CSDH management.
