OBJECTIVE: To compare the effectiveness of calcium alginate swabs and traditional cotton swabs in the control of blood loss after extraction of deciduous teeth from healthy children, aged 3-5 years, under general anaesthetic. DESIGN: Prospective, randomised clinical trial. SETTING: General anaesthetic suite in a dental teaching hospital. SUBJECTS:101 patients were recruited to the study, comprising 50 randomised to be treated with cotton swabs and 51 with alginate swabs. INTERVENTIONS: Teeth were extracted under general anaesthesia and blood collected for measurement in order to compare blood loss using the two systems. MAIN OUTCOME MEASURES: The number of teeth extracted ranged from 1-14. The total blood loss ranged from 0.53-78.13 ml with a median of 12.9 ml. CONCLUSION:Calcium alginate swabs were not found to produce any clinical or statistical advantage over traditional cotton swabs in this surgical setting.
