ObjectivesAcute pulmonary embolism is a major cause of morbidity and mortality in patients presenting for emergent cardiac surgery with overall mortality ranging from 6% to as high as 85%. While the initial focus of treatment is nonsurgical or percutaneous interventions, surgical treatment continues to be a treatment for patients with refractory thrombus burden or cardiogenic shock. Our institution regularly performs surgical pulmonary embolectomy with improved outcomes compared to current reports. We thus performed a retrospective analysis of outcomes of pulmonary embolectomy patients and anesthetic management.DesignA retrospective review of 40 patients undergoing emergent pulmonary embolectomy over a 4 year period (2008-2012) at our institution was performed to assess for a 2nd period of critical instability.SettingThe study was conducted at a tertiary, level 1, trauma university medical center.ParticipantsThe study was performed through chart review of patient hospital records.InterventionsNo interventions were performed.MeasurementsAnesthetic records were reviewed along with echocardiographic records and surgical reports to assess cardiac function, need for emergent cardiopulmonary bypass, and degree of patient morbidity.ConclusionsA total of 40 patients were studied. Hemodynamic instability occurred in 12.5% of patients at time of induction requiring emergent cardiopulmonary bypass. Another 17% of patients who remained stable following induction developed subsequent instability requiring emergent cardiopulmonary bypass during pericardial opening or manipulation which has not been previously reported. One patient died during hospitalization. Patients who required emergent bypass following induction of general anesthesia tended to receive higher doses of induction drugs than the other groups. In patients who needed emergent bypass during pericardial manipulation there were no identifiable factors suggesting that these patients remain at risk despite a stable post-induction course.Copyright © 2014 Elsevier Inc.
