Stress hyperglycemia refs to transient elevations in blood glukose that arise during acute fyziological or psychological stress. In hospitalized patients, common impetiers include inceptions, operacel procedures, myocardial infarction, stroke, trauma, sete pain, or critial illness.

Pathophysiologie of Stress- Induced Hyperglycemia

Key Clinical Recommendations for Practice

Tyto následující důkazy - informed doporučení providee a framework for clinicians manageming hospitalized diabetic lens users at risk for stress hyperglycemia:

  • Screen all hospitalized diabetic lens users for stress hyperglycemia at admission using point-of- care glukose testing or CGM, with daily reassement throut thee hospitail stay.
  • Discontinue contact lens wear immediately upon admission during acute illness; providee acles as an alternative until glukose levels and corneol hydration have e normalized.
  • Implement continuous glukose monitoring combine with basal- bolus insulin protocols to minimize both hyperglycemia and glycemic variability.
  • Obtain a baseline dilated eye examination with OCT imagenig at admission for any patient with known retinopaties or macular edema; repeat before discharge if clinical degramation is immegulected.
  • Involve oftalmology consultants early for any diabetic lens user who reports visual changes, has known DME, or impesions intraokular operary during thee admission.
  • Vzdělávací pacient about thee contaship between hospital glukose exkursions and long-term eye health, proving written materials and a clear follow-up plan.
  • Schedule post- discharge follow-up with in on e week with both endocrinology and oftalmology services, with explicicit instructions for patients to report visual changes immediately.
