Yoshii T, et al. - Researchers assessed the effectiveness of 2 standard antiseptic solutions, chlorhexidine-gluconate (CHG) and povidone-iodine (PD-I), in eliminating bacterial pathogens from surgical sites in posterior spine surgeries. However, an equal effectiveness of CHG-ethanol and PD-I at eliminating the bacterial flora from the surgical site was noted, a more favorable long-lasting effect for skin antisepsis in posterior spine surgeries was demonstrated by CHG-ethanol.
