Schulke Microshield 4% Chlorhexidine Surgical Handwash 500ml – Preoperative Antimicrobial Cleanser

Product Overview

Microshield 4 is a hospital-grade antiseptic handwash containing 4% w/v chlorhexidine gluconate, manufactured by Schulke, a global leader in infection prevention solutions. Chlorhexidine gluconate is the gold-standard surgical hand antiseptic due to its broad-spectrum bactericidal activity, rapid onset of action and sustained residual effect that persists through gloving. The formulation is designed for undiluted use, requiring only 5 ml per application for routine handwashing and repeated applications for a full surgical scrub protocol.

The product incorporates skin-conditioning agents to minimise the drying and irritation associated with frequent handwashing in healthcare settings. Microshield 4 demonstrates bactericidal efficacy against Gram-positive organisms including MRSA, Gram-negative bacteria, and enveloped viruses. The persistent antimicrobial activity of chlorhexidine gluconate on the skin surface provides ongoing protection between hand hygiene events, a critical feature in operating theatre and intensive care environments.

Frequently Asked Questions

How does Microshield 4 compare to alcohol-based hand rubs?

Chlorhexidine gluconate handwash and alcohol-based hand rubs serve complementary roles in surgical hand hygiene. WHO guidelines recommend either a chlorhexidine-based surgical scrub or an alcohol-based surgical hand rub for preoperative hand preparation. Microshield 4 provides persistent residual antimicrobial activity that alcohol-based products do not, making it preferred when sustained bacterial suppression beneath surgical gloves is required.

Is Microshield 4 suitable for patients with sensitive skin?

Microshield 4 contains skin-conditioning agents to minimise irritation. However, it is contraindicated in patients with known hypersensitivity to chlorhexidine gluconate. For healthcare workers experiencing contact dermatitis from chlorhexidine, Schulke offers alternative formulations such as Microshield 2 (2% chlorhexidine) or non-chlorhexidine options. Patch testing should be considered for individuals with a history of antiseptic sensitivity.

What is the recommended surgical scrub protocol?

For surgical hand scrubbing, wet hands and forearms, apply 5 ml of Microshield 4, and wash for 2 minutes covering all surfaces of hands and forearms to the elbow. Rinse and repeat the 2-minute wash. This protocol achieves a sustained 3-log reduction in resident skin flora as required by surgical hand antisepsis standards.

What regulatory approvals does Microshield 4 hold?

Microshield 4 is registered with the Australian Therapeutic Goods Administration (TGA) under ARTG number 387456. It is also listed with HSA Singapore for import and supply. The product is manufactured by Schulke under ISO 13485 certified quality management systems and meets the requirements for surgical hand antiseptic agents.
