From Mr J. D. Topham, MRPharmS
SIR,—I was pleased to see in David Morgan's article on wound care products (PJ, November 20, p820) that the deodorising properties of sugar pastes are mentioned. He also states that sugar may exert its antibacterial effect by competing for water present in the cells of bacteria. This is clearly shown by Loncin and Merson1 and Chirife et al.2
Both sugar and honey3 are widely used to treat wounds. They need the addition of an adhesive hydrogel (gum)4 to enable them to absorb exudate and reduce or eliminate scarring. I found that daily or alternate day dressing changes did not produce the trauma to patients associated with frequent dressing changes experienced by Seal and Middleton.5 I also found that when excessive quantities of exudate were produced, these were held in the thin ventilated polythene covering6 with no apparent inhibition of the healing process.
A disadvantage of the paste used at Northwick Park hospital by Middleton and Seal7 is that, in some wounds, hypergranulation (excessive flesh) occurs. I discovered that the presence of povidone prevented this.8
