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...

Assessment of the Cardiovascular System II: Inspection

Inspection is the initial step in assessing the cardiovascular system. It involves a detailed visual examination that provides crucial information about a patient's circulatory and cardiac health. This systematic process, conducted from head to toe, helps identify signs of cardiovascular conditions by observing physical appearance, skin and mucous membranes, jugular and carotid pulsations, chest symmetry, and the condition of the extremities.

Assessment of the Cardiovascular System III: Palpation

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...

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...

Summary

Median sternotomy (surgical incision) scars can cause problems, with 22% of patients experiencing symptoms like itching or poor appearance. About 10% develop hypertrophic scarring, indicating a need for preventative scar treatments.

Area of Science:

  • Cardiovascular Surgery
  • Dermatology
  • Wound Healing

Background:

  • Median sternotomy is a common surgical approach for cardiac procedures.
  • Sternotomy wound healing can result in problematic scarring.
  • This study investigates the incidence and characteristics of median sternotomy scars.

Purpose of the Study:

  • To evaluate the quality of median sternotomy scars.
  • To compare sternotomy scar outcomes with other scar types.
  • To identify factors influencing poor scar formation.

Main Methods:

  • Assessed 50 patients with mature median sternotomy scars.
  • Utilized the Patient and Observer Scar Assessment Scale (POSAS) and Manchester Scar Scale (MSS).
  • Photographic documentation and clinical evaluation of scar features were performed.

Main Results:

  • 22% of patients reported symptomatic or poor scars (itching, cosmetic concerns).
  • 10% of patients exhibited hypertrophic scarring as assessed by clinicians.
  • Predominant clinician concerns included scar color, variable relief, and increased contour.

Conclusions:

  • Median sternotomy scarring can be problematic, affecting a significant patient subset.
  • A low but significant rate of scar issues, including hypertrophic scarring, was observed.
  • Preventative scar management strategies should be considered for median sternotomy patients.
