Outcome from mechanical ventilation after autologous peripheral blood stem cell transplantation

To report the outcome of patients with autologous peripheral blood stem cell transplantation (PBSCT) receiving mechanical ventilation.

Retrospective observational study.

Active hematopoietic stem cell transplantation center and a university hospital medical ICU.

Patients with autologous PBSCT receiving mechanical ventilation.

A review of the medical records of patients with autologous PBSCT receiving mechanical ventilation. Data collection was restricted to the first episode of mechanical ventilation.

A total of 78 autologous PBSCT patients received mechanical ventilation for > 24 h. Twenty patients (26%) were extubated and discharged alive from the hospital. Thirteen hospital survivors (60%) were alive at 6 months. Lung injury (LI), vasopressor use, and hepatic and renal failure (HRF) were used to predict survival after mechanical ventilation. Sixty patients (76%) had no organ failure, or had isolated LI or only required treatment with vasopressors. Their hospital survival and 6-month survival were 32% and 20%, respectively. Hospital and 6-month survival for the patients with HRF or LI and vasopressor use was 6% and 0%, respectively.

Prolonged mechanical ventilation and aggressive ICU support is justified for autologous PBSCT patients receiving mechanical ventilation with no organ failure, or who have only isolated LI, or who only require treatment with vasopressors.
