1. Alcohol based hand rub vs
Alcohol based hand rub vs. traditional surgical scrub and the risk of wound infection: a randomized controlled trial.
Dr Mohammed Al Naami FRCSC,FACS,MEd.
Dr Muhammad Farooq Afzal MD,FCPS,FRCSEd

2. Background
Drawbacks of traditional hand scrub with povidone or Hibiscrub
Mechanical trauma to skin(Kovach 2001)
Dryness and irritation due to detergent nature.(Kikuchi 1999)
Drawbacks of using water
Splash, contamination,need to adjust temperature,leakage,cost

3. Can alcohol be a suitable alternative?
Alcohol is an established disinfectant.
*Parenti et al have shown that no difference in the risk of wound infection when alcohol gel sterillium is used in comparison to traditional surgical scrub.
Suitable in local circumstances as water is a scarce resource in the kingdom.
But why the use of traditional method still popular?

4. Why alcohol gel is not used ?
Lack of convincing evidence.(no Meta analysis)
Only one trial has published.
Ethical Problem related to use of alcohol.
Change???difficult

5. Study question
To determine the efficacy of alcoholic hand rub in the prevention of wound infection in clean surgery as compare to the traditional surgical scrub.
Primary end point(dependent variable)
Rate of wound infection
Secondary end point
Compliance,Skin tolerance

6. Protocol
Approval from Research and ethical committees and Infection control
Informed consents from the patient
Study design: a single blind randomized controlled trial
Randomization:Two groups for all eligible patients. In one group, the surgeon would use the traditional scrub method whereas in the second group the alcohol based hand rub would be used for hand disinfection before surgery. Randomization would be done using opaque sealed envelopes

7. Protocol……….2
Blinding would be done by ensuring that those who look for the wound infection or interpret the microbiological results should not know the allocation group.
Sample size: For a power of 80 and an alpha of 0.05,more than 4000 patients are required,
Initially 250 patients with in each group(pilot study)
Inclusion criteria: All patients undergoing clean and clean contaminated operations. All patients would be matched for confounders and would have same skin prep and drape method.
Exclusion criteria: Contaminated and dirty operation.

8. Methodology
Two groups would be made. One group would use the traditional three minutes method of scrubbing with povidone iodine or hibiscrub then washing with water The other group now using the 10 ml alcohol hand rub for hand disinfection without using water for one minute prior to OR. In case of soiling of the hands, washing would be done prior to use of alcohol hand rub.The composition of the alcohol rub is propanol-1,propanol –2 and mecetronium etilsulfate.(Purrrel TM).

9. Methodology……..2
Tool for data recording: Two CRF(clinical report forms)
Setting: OR of King Khalid university hospital
Study enrollment: Feb 15,2006 to Aug 15,2006.
Follow up: Patient would be followed up at one week and one month intervals from the day of operation

10. Methodology…………3
Wound infection would be defined according to the CDC definition of surgical site infection(CDC guidelines 1992) as:
“Increasing Pain,Redness or cellulites with discharge of pus from the whole or part of the wound with or without positive bacterial culture within 30 days of operation”.
Bacterial swab would be taken and culture and sensitivity would be done.
Analysis Chi Square analysis for categorical variables using the SPSS 11.5.
