Whole-lung Lavage and Pulmonary Alveolar Proteinosis: Review of Clinical and Patient-centered Outcomes.

OBJECTIVE: The objective of this retrospective review was to evaluate the perioperative and procedural management of patients with pulmonary alveolar proteinosis (PAP) who presented for whole-lung lavage (WLL). DESIGN: The records of all adult patients with PAP who underwent WLL between January 1, 1988 and August 20, 2017 were reviewed and pertinent demographic, preoperative, anesthetic, procedural, and postoperative data were recorded. SETTING: Large academic tertiary referral center. PARTICIPANTS: Forty patients with PAP underwent 79 WLL procedures. INTERVENTIONS: Patients with PAP undergoing WLL. MEASUREMENTS: Successful WLL, defined by visual clearing of lavage fluid, was completed in 91% of cases. Whole-lung lavage was terminated prematurely in 9% of cases (refractory hypoxia most common), while 8% of cases were found to have 30-day complications. There were no cases of intraoperative death, hemodynamic collapse, pneumothorax or hydrothorax, or need for emergent reintubation. Postoperative clinical follow-up at the authors' institution within 6 months of WLL showed 68% of patients reported improvement in symptoms and/or functional status. CONCLUSION: The authors here present a retrospective study describing the perioperative and procedural management of PAP patients undergoing WLL to help familiarize providers with the management of this population (Fig 1). The findings of this study outline a successful and consistent approach to WLL using a multidisciplinary team experienced in this procedure. Even in experienced hands, procedural complications and 30-day postoperative complications emphasize the risk in this complex patient population.

Whole-lung lavage in a patient with pulmonary alveolar proteinosis.

Pulmonary alveolar proteinosis (PAP) is a rare syndrome in which phospholipoproteinaceous matter accumulates in the alveoli leading to compromised gas exchange. Whole-lung lavage is considered the gold standard for severe autoimmune PAP and offers favorable long-term outcomes. In this case report, we describe the perioperative management and procedural specifics of a patient undergoing WLL for PAP in which an anesthesiologist serves as the proceduralist and a separate anesthesiologist provides anesthesia care for the patient.

Bivalirudin and transcatheter aortic valve replacement: a cautionary tale.

Bivalirudin is an accepted alternative to heparin for anticoagulation during select cardiac procedures. Its use has not been well described during transcatheter aortic valve replacement. Herein is the report of a transcatheter valve replacement case that was complicated by catastrophe and need for emergent cardiopulmonary bypass. A successful outcome was achieved. However, the inability to rapidly reverse the anticoagulation effect of bivalirudin proved troublesome, and that provides for a cautionary tale about its use during transcatheter valve replacement.

Spinal cord protection during open repair of thoracic and thoracoabdominal aortic aneurysms using profound hypothermia and circulatory arrest.

BACKGROUND: Reduced risk of paraplegia is argued as an advantage of endovascular repair of descending thoracic aortic aneurysms (DTA) and thoracoabdominal aortic aneurysms (TAAA); however, paraplegia rates with open repair vary widely. STUDY DESIGN: We identified consecutive patients undergoing open repair of TAAA or DTA with or without arch replacement using profound hypothermia and circulatory arrest as a spinal cord protection strategy on a single surgical service between June 1, 2001 and September 20, 2010. RESULTS: Ninety-nine procedures were performed in 94 patients with a mean age of 59 years (range 19 to 84 years), 56 of whom were male (60%). The extent of repair was TAAA in 37 (Crawford extent I in 6, extent II in 28, and extent III in 3), DTA in 37, and DTA plus arch in 25. Surgery was urgent or emergent in 25 patients (25%). Operative mortality (30-day) was 10% (10 of 99), including a mortality of 12% for arch DTA (3 of 26), 11% for TAAA (4 of 25), and 5% for isolated DTA (2 of 37). There were 11 (11%) strokes and 11 patients experienced renal failure (7 with dialysis). There were 15 late deaths and survival at 5 years was 74% (95% CI, 62.4-88.2%). No patients experienced paraplegia, although one had delayed paraparesis thought to be secondary to refractory hypotension postoperatively. CONCLUSIONS: Although the mortality and stroke risks for patients undergoing repair of DTA or TAAA using profound hypothermia and circulatory arrest are substantial, the risk for paraplegia is low. In appropriately selected patients, profound hypothermia and circulatory arrest should be the preferred technique for spinal cord protection for DTA and TAAA.

Use of paravertebral blockade to facilitate early extubation after minimally invasive cardiac surgery.

We retrospectively reviewed the first 14 patients who received preoperative paravertebral blockade prior to minimally invasive cardiac surgical procedures. The use of paravertebral blockade along with an anesthetic technique designed to facilitate rapid recovery allowed early extubation in the operating room or intensive care unit in all but one patient. Extubated patients leaving the operating room were comfortable. No postoperative respiratory complications occurred.
