Surgical Infections
|January 19, 2019
Summary
Alcohol hand rubs offer comparable or better bacterial reduction than traditional surgical scrubs. Studies show no difference in surgical site infections, making alcohol rubs a viable alternative for surgical hand preparation.
Area of Science:
- Infection Control
- Surgical Hygiene
- Microbiology
Background:
- Alcohol rubs are proposed as an alternative to traditional surgical scrubs for hand preparation.
- Limited critical reviews exist on the evidence supporting alcohol rubs over traditional scrubs.
Purpose of the Study:
- To review evidence comparing surgical scrubbing and alcohol rubs for hand preparation.
- To assess bacteriologic and clinical outcomes of both methods.
Main Methods:
- A comprehensive literature review was conducted.
- Studies comparing conventional surgical scrubbing with alcohol rubs were analyzed.
Main Results:
- Alcohol rubs demonstrated comparable or superior bacterial reduction on hands.
- No significant difference in surgical site infection rates was found between the two methods.
Conclusions:
- Alcohol rubs are a reasonable alternative to surgical scrubs for hand preparation.
- The evidence supports the efficacy of alcohol rubs in surgical settings.

6.0K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

2.0K
The operational amplifier, often referred to as an op-amp, is a multifaceted building block of a circuit. This electronic component functions like a voltage-controlled voltage source and can also be used to create a voltage- or current-controlled current source. The design of an operational amplifier enables it to execute mathematical operations when external components like resistors and capacitors are linked to its terminals. An op-amp has the capacity to sum signals, amplify a signal,...

The concept of real numbers includes all the values that can be represented on a continuous number line. The system began with basic counting values used for enumeration. It later expanded to include values that represent the absence of quantity and opposites of the counting values. When situations required expressing parts of a whole or dividing quantities evenly, values capable of representing such proportions were developed. When written using decimal notation, these values can end or repeat...

Vectors are physical quantities that have both magnitude and direction. The vector operations include addition, subtraction, and scalar multiplication.
A vector multiplied by a scalar value is called scalar multiplication. The result obtained is a new vector with a different magnitude. If the scalar is positive, the direction of the vector remains the same, but if it is negative, the direction of the vector is reversed. For example, the product of the mass and velocity yields the momentum.

Operant conditioning, a key concept in behavioral psychology, involves using reinforcement and punishment to alter the likelihood of a behavior being repeated. B.F. introduced this type of conditioning. Skinner focused on voluntary behaviors and the consequences that follow them, influencing whether these behaviors will be strengthened or diminished.
Reinforcement in operant conditioning can be positive or negative, both of which serve to increase the likelihood of a behavior. Positive...
