Objective This study aimed to investigate the causes and influencing factors of unplanned reoperations and to propose strategies for reducing their incidence.Methods A retrospective analysis was conducted by comparing medical records of patients with and without unplanned reoperations at a tertiary general hospital in Guangxi throughout 2024.Descriptive statis-tics,chi-square tests,and logistic regression were used to analyze contributing factors.Results Among 43,612 surgeries per-formed in 2024,135 unplanned reoperations were recorded,yielding an overall incidence of 3.09％o.The main causes included postoperative bleeding,complications(e.g.,fistula,infarction,thrombosis),and incision-related issues(e.g.,infection,poor healing).Significant differences(P＜0.05)were observed between the reoperation and non-reoperation groups in gender(x2=11.654),age(x2=19.393),grade of initial surgery(x2=12.405),surgeon's title(x2=14.572),nature of initial surgery(x2=20.287),and patient case classification(x2=21.578).These variables were also identified as significant influencing fac-tors(P＜0.05),with gender,age,nature of surgery,grade Ⅲ surgery,and case classification types B/D being independent risk factors.Conclusion Unplanned reoperation serves as a key indicator of surgical quality and safety.Interventions such as en-hanced hospital-and department-level management,perioperative process optimization,and surgical service mechanism improve-ments are recommended to reduce the incidence of unplanned reoperations.

Objective To study the influence of different starting time of hyperbaric oxygen(HBO) therapy on severe brain injury patients.Methods 60 cases of acute cerebral infarction patients were divided into 2 groups,namel 48 hours to 7 days group(group A) and 8 days to 15 days group(group B) after injury.Fugl-Meyer assemment and modified Barthel index were employed to assess the patients before and after HBO for 30 days in the 2 groups.Results After 30 days of HBO therapy the Fug-Meyer assemment and modified Barthel index in the A group were better than those of B group,there were significant differences between the 2 groups(P
