The traditional care of patients with subacute/chronic subdural haematoma (S/CSDH) often involves delayed mobilization after burr-hole drainage. It is thought that delayed mobilization aids brain re-expansion thereby reducing the risk of recurrence. However, there is paucity of information regarding its efficacy and safety over early mobilization. We evaluated the efficacy and complications of each type of mobilization following burr-hole drainage of S/CSDH. This was a prospective study from October 2004 and September 2010. A total of 50 patients who had burr-hole drainage of S/CSDH were sequentially allocated to either early (day 2) or late (day 7) mobilization (EM or LM) groups (25 patients in each group). Wound related complications, recurrence of haematoma, complications of prolonged bed rest and Glasgow Outcome Score (GOS) at discharge were studied in the two groups. Patients who could not obey commands to mobilize in the early post-operative period were excluded. There were 43 (86%) males and 7 (14%) females. The mean age was 57 years (range: 27-90 years). Fourteen (28%) of the patients were elderly (age > 65 years). Two complications, wound infection in a 76-year old man in the LM group and tension pneumocephalus requiring re-opening burr-hole drainage in a 55-year old man in the EM group were recorded. There was no recurrence or problem associated with prolonged bed rest in the two groups. Five (10%) patients had moderate disability (GOS 4) at discharge (1 EM, 4 LM) while the others (90%) had good recovery (GOS 5) (24 EM, 21 LM). These differences were not statistically significant (p-value: 0.349). It appears that both EM and LM are equally beneficial in the post-operative care of patients following burr-hole drainage of S/CSDH. There is no significant complication referable to the specific type of mobilization. The authors, therefore, advocate EM of patients to reduce the length of hospital stay.
