Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

13.9K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Area of Science:

  • Surgical Skills Training
  • Microsurgery Assessment
  • Medical Education Research

Background:

  • Microsurgery is a complex skill with poorly understood performance factors.
  • Identifying these factors is crucial for effective microsurgeon training and evaluation.
  • Current understanding of microsurgical skill acquisition needs further development.

Purpose of the Study:

  • To identify factors correlating with microsurgical performance in fellows.
  • To evaluate the relationship between specific technical elements and overall skill.
  • To inform the development of competency standards in microsurgery training.

Main Methods:

  • 29 microsurgery fellows evaluated over a 1-year fellowship.
  • Clinical and laboratory assessments of microsurgical anastomosis performance.
  • Validated assessment tools used for real-time and video-recorded evaluations.

Main Results:

  • Clinical performance correlated with speed, instrument handling, and motion.
  • Laboratory performance linked to instrument handling, operative flow, and steps; inversely with time.
  • Common errors included unequal stitch bites, tissue damage, and loose knots.

Conclusions:

  • Speed, instrument handling, operative flow, and motion are relevant to microsurgical anastomosis performance.
  • Further prospective trials are needed to define competency in microsurgery training.
  • Objective and subjective factors should be considered in microsurgical skill assessment.
