Background: A double-blind randomised control study was conducted on all patients who
were admitted or referred to the Department of Neurosurgery, Sultanah Aminah Hospital, Johor
Bahru, with a diagnosis of hydrocephalus where a ventriculoperitoneal shunt was indicated.
Methods: The period of study was from November 2005 to May 2007, and the follow-up
period was 3 months after surgery. Randomisation was carried out in the operating room prior
to the procedure. The scrub nurse selected a sealed envelope, which contained the assignment of
each patient to 1 of 2 treatment groups: Group 1 patients were treated with topical methicillin, and
Group 2 patients were not treated with topical methicillin. Prophylactic antibiotic, cefuroxime (25
mg/kg) was given intravenously at induction. Standard sterile operative technique was followed in
preparing and draping the patients.
Results: A total of 90 patients were recruited in the study, and 13 (14.4%) patients developed
an infection within 3 months post-operation. Group 1 had a 8.9% risk of infection, and Group 2 had
a 20% risk; however, there was no statistically significant post-operative ventriculoperitoneal shunt
(VPS) infection reduction with the use of topical methicillin in VPS surgery (P = 0.230). Multivariate
analysis showed that only duration of surgery had a significant influence on the incidence of postoperative
VPS infection in the non-methicillin group (P = 0.02). The non-methicillin group had an
8 times greater risk of developing post-operative VPS infection than the methicillin group if surgery
lasted longer than 1 hour.
Conclusion: Topical methicillin had no significance in the reduction of post-operative VPS
infection.

Background: Mortality and morbidity associated with intracerebral HemorrhageICH is still high. Up to now, there are no evidence-based effective treatments for acute ICH. This study is to assess the effect of tranexamic acid (TXA) on hematoma growth of patients with spontaneous ICH compared to a placebo.
Methods: We performed a single-blinded, randomised placebo-controlled trial of TXA (intravenous 1g bolus, followed by infusion TXA 1 g/hour for 8 hours) in acute (< 8 hours) primary ICH. Strict blood pressure control (target SBP 140-160 mmHg). A repeat Computed Tomography brain was done after 24 hours to reassess hematoma growth. The primary objective is to test the effect of TXA on hematoma growth. Other objective was to test the feasibility, tolerability, and adverse events of TXA in primary ICH.
Results: Statistical analysis showed significant hematoma growth in control group after 24 hours compared to baseline (14.3300 vs 17.9940, P = 0.001) whereas the treatment group there is no significant hematoma size expansion between baseline and after 24 hours (P = 0.313).
Conclusions: This study showed a significant hematoma volume expansion in the control group compared to the treatment group.
