Peripheral Artery Disease V: Postoperative Nursing Management01:23

Peripheral Artery Disease V: Postoperative Nursing Management

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
Diabetic Foot Ulcer01:31

Diabetic Foot Ulcer

Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory neuropathy reduces pain perception,...
Diabetic Retinopathy01:27

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
Healing II: Complications01:24

Healing II: Complications

Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...

Area of Science:

  • Cardiovascular Research
  • Surgical Science
  • Critical Care Medicine

Background:

  • Perioperative complications persist despite optimized hemodynamics.
  • Microcirculatory dysfunction impacts organ perfusion during surgery.
  • Abnormalities in microcirculation are associated with prognosis in surgical patients.

Purpose of the Study:

  • To review recent research on perioperative microvascular alterations.
  • To emphasize direct visualization techniques of human microcirculation.
  • To explore the impact of surgical procedures and interventions on microcirculation.

Main Methods:

  • Review of recent studies on direct microcirculation visualization.
  • Analysis of indirect quantification methods for organ perfusion.
  • Synthesis of findings on perioperative interventions affecting microvascular function.

Main Results:

  • Surgical procedures and interventions (anesthesia, bypass, drugs, fluids) affect microvascular perfusion.
  • Perioperative microcirculatory abnormalities correlate with patient prognosis.
  • The causal role of microcirculatory alterations in complications is yet to be determined.

Conclusions:

  • Recent studies highlight the incidence and prognostic significance of perioperative microvascular alterations.
  • Further investigation is required to elucidate the complex relationship between microcirculation and perioperative interventions.
