Depressed myocardial function after transurethral resection of prostate
Urology
|May 1, 1981
Summary
Transurethral prostate resection can negatively impact cardiac function, especially with prolonged procedures or undetected fluid overload. Monitoring cardiac pressures is crucial for preventing cardiovascular complications during surgery.
Area of Science:
- Cardiovascular Physiology
- Urologic Surgery
Background:
- Transurethral resection of the prostate (TURP) is a common procedure.
- Cardiovascular complications can arise during TURP.
- Monitoring hemodynamic changes during TURP is essential.
Observation:
- Hemodynamic monitoring via Swan-Ganz catheter and Automated Physiologic Profile was performed on 12 patients undergoing TURP.
- Cardiac and pulmonary pressures, along with other physiologic parameters, were recorded pre- and postoperatively.
- Resection time, body temperature, fluid administration, hemoglobin, and sodium levels were also documented.
Findings:
- 66% of patients showed decreased cardiac index and left ventricular function post-surgery.
- 58% of patients exhibited reduced myocardial function.
- Elevated preoperative pulmonary wedge pressure (PAW > 9 mm Hg) and prolonged resection times (>60 minutes) were associated with depressed cardiac function.
- Changes in cardiac function were not consistently reflected by vital signs, serum hemoglobin, or serum sodium.
Implications:
- Relative hypervolemia and undetected pulmonary wedge pressure elevation are potential contributors to depressed cardiac function during TURP.
- Prolonged resection times increase the risk of cardiovascular complications.
- Proactive hemodynamic monitoring and management are vital for mitigating cardiac risks in TURP patients.
