Haemodynamic changes detected during open prostatectomy and transurethral resection for benign prostatic hyperplasia

Area of Science:

• Anesthesiology
• Cardiovascular Physiology
• Urology

Background:

• Benign prostatic hyperplasia (BPH) is a common condition requiring surgical intervention.
• Prostatectomy, either transurethral or open, are common surgical options.
• Intraoperative hemodynamic stability is crucial for patient outcomes.

Purpose of the Study:

• To compare intraoperative hemodynamic differences between transurethral resection of the prostate (TURP) and open prostatectomy.
• To investigate the impact of prostatectomy type on hemodynamic parameters.
• To assess the role of mild hypothermia in observed hemodynamic changes.

Main Methods:

• Sixty patients undergoing prostatectomy for BPH were evaluated.
• Patients were divided into transurethral (n=18) and open (n=42) prostatectomy groups.
• General anesthesia was administered uniformly; cardiac output and temperature were monitored at five intervals.

Main Results:

• No significant intraoperative hemodynamic differences were observed between the two surgical groups.
• All patients exhibited significant decreases in cardiac output and increases in systemic resistance during surgery.
• A mild, insignificant decrease in body temperature was noted, potentially contributing to hemodynamic derangement.

Conclusions:

• The type of prostatectomy (transurethral vs. open) does not appear to cause significant differences in intraoperative hemodynamics.
• Both procedures induce similar mild hemodynamic derangements.
• The surgical approach is unlikely to be a major factor in late mortality rates for these patients.
