Background: Antiseptic skin preparations containing chlorhexidine gluconate and povidone iodine are routinely used to reduce the risk of surgical site infection (SSI). This study assesses the efficacy of two alcohol-based solutions, 2% chlorhexidine-alcohol and 10% povidone iodine-alcohol, on the incidence of cardiac SSI. Methods: A total of 738 consecutive patients undergoing cardiac surgery had skin preparation with 2% chlorhexidine gluconate in 70% isopropanol (ChloraPrep, BD Ltd, UK) were propensity matched to 738 patients with skin prepared with 10% povidone–iodine in 30% industrial methylated spirit (Videne Alcoholic Tincture, Ecolab Ltd, UK). Continuous, prospective SSI surveillance data were collected for all these patients. A retrospective analysis of prospectively collected perioperative data was performed. Results: The overall rate of SSI was similar in the chlorhexidine–alcohol and povidone–iodine–alcohol groups (3.3% versus 3.8%; P = 0.14; relative risk [RR] = 0.98; 95% confidence interval [CI] = 0.52–1.78). Superficial (1.2% versus 1.8%; P = 0.18; RR = 0.97; 95% CI = 0.48–1.80) and deep incisional (1.2% versus 1.6%; P = 0.24) SSI rates were also similar with 10% povidone–iodine–alcohol being marginally more effective against organ-space infections (0.8% versus 0.4%; P = 0.05; RR = 0.38; 95% CI = 0.20–1.01). Conclusion: Our analysis confirms that alcohol-based skin preparation in cardiac surgery with povidone–iodine reduces the incidence of organ-space infections with no significant superiority in preventing incisional SSI compared with chlorhexidine-alcohol.

Background Surgical site infection is a significant cause of morbidity and mortality following caesarean delivery. Objective To determine whether standardising intraoperative irrigation with 0.05% chlorhexidine gluconate during caesarean delivery could decrease infection rates. Methods This was a process improvement project involving 742 women, 343 of whom received low-pressured 0.05% chlorhexidine gluconate irrigation during caesarean delivery over a one-year period. Infection rates were compared with a standard-of-care control group (399 women) undergoing caesarean delivery the preceding year. Results The treatment group infection rate met the study goal by achieving a lower infection rate than the control group, though this was not statistically significant. A significant interaction effect between irrigation with 0.05% chlorhexidine gluconate and antibiotic administration time existed, such that infection occurrence in the treatment group was not dependent on antibiotic timing, as opposed to the control group infection occurrence, which was dependent on antibiotic timing. Conclusion Intraoperative irrigation with 0.05% chlorhexidine gluconate during caesarean delivery did not statistically significantly reduce the rate of infections. It did render the impact of antibiotic administration timing irrelevant in prevention of surgical site infection. This suggests a role for 0.05% chlorhexidine gluconate irrigation in mitigating infection risk whether antibiotic prophylaxis timing is suboptimal or ideal.

Objective: To evaluate the efficacy of pre-cesarean vaginal wash using 5% Povidone Iodine solution on rate of post-cesarean section (CS) surgical site infection and compared with No swabbing. Method: A Prospective Randomized controlled Trial was conducted in department of Obstetrics and Gynecology in Government medical college, Aurangabad. In interventional group, vaginal swabbing with a gauze pieces impregnated with 5% Povidone Iodine solution was done for 30 seconds. The swabbing of vagina was not performed in cases assigned to control group, however the standard surgical preparation of abdomen was done in a usual manner for both group. All subject received prophylactic antibiotic cover. Collected data was complied in pre-designed proforma and analysis was done using SPSS 15. Result: The risk of post operative fever and wound infection was significantly reduced in interventional group. No measure difference was noted in seroma and composite wound infection. Also less duration of hospital stay in interventional group was noted. No adverse effect of use of Povidone iodine was reported in the interventional group. Conclusion: Vaginal swabbing with 5% Povidone-iodine pre- LSCS is inexpensive and simple intervention even for low resource setting to decrease surgical site infection.

Showering preoperatively with chlorhexidine gluconate is an issue that continues to promote debate; however, many studies demonstrate evidence of surgical site infection risk reduction. Methodological issues have been present in many of the studies used to compile guidelines and there has been a lack of standardisation of processes for application of the active agents in papers pre-2009. This review and commentary paper highlights the potential for enhancing compliance with this low-risk and low-cost intervention and provides some guidance for enhancing implementation of preoperative showering with both chlorhexidine in solution and impregnated wipes.
