Pros and cons of urgent exploratory sternotomy after open cardiac surgery
Insights
Urgent exploratory sternotomy is appropriate for life-threatening open-heart surgery complications. This procedure showed high survival rates for cardiac arrest, hypotension, and bleeding, despite longer recovery times for critical cases.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
Background:
- Life-threatening complications can arise during open-heart procedures.
- Urgent intervention may be necessary to manage these critical events.
Purpose of the Study:
- To evaluate the appropriateness and outcomes of urgent exploratory sternotomy for immediate post-open-heart surgery complications.
- To assess survival rates and postoperative morbidity associated with this emergency procedure.
Main Methods:
- Retrospective review of 100 patients undergoing exploratory sternotomy between December 1982 and December 1984.
- Patients were divided into two groups: Group 1 (cardiac arrest or acute profound hypotension) and Group 2 (persistent excessive bleeding).
- Analysis of causes for sternotomy, survival rates, postoperative stay, and complications.
Main Results:
- High survival rates were observed: 83% for patients with acute profound hypotension and 85% for those with excessive bleeding.
- Cardiac tamponade and myocardial ischemia were primary causes in Group 1.
- Identifiable correctable bleeding sites were found in 78% of Group 2 patients.
- Group 1 patients experienced longer postoperative stays and required more ventilatory support.
Conclusions:
- Urgent exploratory sternotomy is an effective and appropriate intervention for managing life-threatening complications after open-heart surgery.
- The procedure is associated with high survival rates, even in critically ill patients.
- While associated with increased resource utilization in severe cases, sternotomy offers a vital rescue option.
Abstract:
To determine whether it is appropriate to perform urgent exploratory sternotomy for potentially life-threatening complications of open-heart procedures, the authors reviewed the charts of 100 such patients managed by exploratory sternotomy between December 1982 and December 1984. Group 1 comprised 32 patients who suffered cardiac arrest (8) or had acute profound hypotension (24). Group 2 included 68 patients with persistent excessive bleeding. Of group 1 patients operated because of acute profound hypotension, 50% had definite evidence of cardiac tamponade. In the remainder the cause was severe myocardial ischemia and left ventricular failure. In group 2 an identifiable correctable site of bleeding was found in 78%. Four of the 8 patients with cardiac arrest and 20 (83%) of the 24 patients with acute profound hypotension survived and left the hospital. In group 2, 58 (85%) of the 68 survived. The mean postoperative stay was higher in group 1 than group 2-20.3 +/- 3.08 days versus 14.2 +/- 1.23 days (p less than 0.1). The duration of ventilatory support in group 1 was also higher - 6.18 +/- 1.32 days versus 2.12 +/- 0.38 days. Postoperatively, sputum cultures gave positive results in 19% of the patients, all of whom had required prolonged ventilatory support. Minor sternal wound infections were present in two and major in four. There was no significant difference in morbidity of the survivors between those who underwent sternotomy in the recovery room or in the operating room.(ABSTRACT TRUNCATED AT 250 WORDS)
