Placing patients in an upright position during breast surgery is safe and effective for evaluating breast shape. Cardiovascular parameters remained stable, showing no clinical significance of instability.

Area of Science:

  • Plastic Surgery
  • Cardiovascular Physiology

Background:

  • Accurate breast shape assessment is crucial for aesthetic and reconstructive surgery.
  • Surgeons often avoid the upright position due to concerns about hemodynamic instability.

Purpose of the Study:

  • To prospectively evaluate cardiovascular parameters in patients undergoing breast procedures in an upright position.
  • To determine the clinical significance of hemodynamic changes in the upright seated position during breast surgery.

Main Methods:

  • Prospective measurement of heart rate and mean arterial pressure in 30 patients.
  • Data collection on duration and frequency of upright positioning during breast surgery.
  • Measurements taken before and after elevating the patient to an 80-90 degree upright position.

Main Results:

  • Average supine mean arterial pressure was 73 mmHg; upright was 70 mmHg.
  • Average supine heart rate was 73 bpm; upright was 76 bpm.
  • Statistically significant (p < 0.05) but clinically insignificant changes in cardiovascular parameters were observed; no patient required repositioning due to instability.

Conclusions:

  • The upright seated position is safe and effective for intraoperative breast shape evaluation.
  • No clinically significant hemodynamic instability occurred in patients placed upright.
  • A method for safely achieving the upright position during breast surgery is presented.
