 What are surgical gloves, and why are they important in medical settings?

Surgical gloves are sterile, disposable gloves made from materials like latex, nitrile, or neoprene, designed to protect both healthcare workers and patients during medical procedures. They act as a barrier against infections, preventing the transmission of pathogens, bloodborne diseases, and contaminants. For surgeons and medical staff, gloves reduce the risk of exposure to bodily fluids, chemicals, and sharp instruments. For patients, they minimize the chance of surgical site infections (SSIs) caused by bacteria from the healthcare provider’s hands. Proper glove use is a critical component of aseptic technique in operating rooms, dental clinics, and other medical environments, ensuring safety and hygiene compliance.

Surgical gloves are primarily made from latex, nitrile, or neoprene, each with distinct properties. Latex gloves offer excellent elasticity, comfort, and tactile sensitivity, making them popular in surgery, but they can trigger allergic reactions in some individuals. Nitrile gloves are a synthetic alternative, providing superior puncture resistance and chemical protection, making them ideal for high-risk procedures and those with latex allergies. Neoprene gloves are less common but offer good chemical resistance and durability. 

Additionally, gloves vary in thickness, powder-free vs. powdered options (powdered gloves are being phased out due to potential complications), and textured surfaces for better grip. The choice depends on factors like allergy risks, procedure type, and required dexterity.

Are plastic face shields effective against COVID-19 and other infections?

Plastic face shields provide some protection but are not enough alone. They block large droplets from coughs or sneezes, which helps protect the eyes and face. However, they do not filter small airborne particles like masks do.

For optimal protection, health authorities like the CDC and WHO recommend using face shields in combination with well-fitted, high-quality masks such as N95s or KN95s rather than as a standalone solution. This combination approach is particularly important in high-risk settings like healthcare environments or crowded indoor spaces. While shields alone may be better than no protection at all, they should be viewed as a supplementary measure rather than a primary defense. The most effective strategy against COVID-19 and other airborne illnesses remains vaccination, proper mask-wearing, good ventilation, and hand hygiene, with face shields serving as an optional extra layer when appropriate.
