Perioperative management of patients with left ventricular assist devices undergoing noncardiac procedures: a survey of current practices.
Journal of Cardiothoracic and Vascular Anesthesia 2015 Februrary
OBJECTIVES: To describe perioperative management of patients with left ventricular assist devices (LVAD) in noncardiac procedures.
DESIGN: Survey of (1) respondent demographic characteristics, (2) anesthetic practices for LVAD patients having endoscopies, and (3) low-risk surgeries requiring general anesthesia.
SETTING: Internet-based.
PARTICIPANTS: Society of Cardiovascular Anesthesiologists membership.
INTERVENTIONS: None.
MEASUREMENTS AND MAIN RESULTS: Inpatient endoscopic procedures were done mainly in the endoscopy suite (71.7%) by a solo practitioner or 1:1 staffing ratio 59% of the time. LVAD-specific support personnel were present in more than 80% of all procedures. Both endoscopy and surgical patients used post-anesthesia recovery units and intensive care units for recovery; however, compared with endoscopy patients, surgical patients recovered in the ICU more frequently (45.5% v 29.1%, p<0.001). In addition, 18% of endoscopy patients recovered on site. Regarding patient monitoring, more than 90% of responders used electrocardiogram, pulse oximetry, end-tidal CO2, and blood pressure monitors on LVAD patients. Responders reported using arterial catheters to monitor blood pressure in 49% of endoscopy cases and 71% of surgical patients. The reported use of invasive monitors by individual clinicians was related inversely to institutional LVAD volume (p = 0.04 and p = 0.01 in endoscopy and surgical procedures, respectively).
CONCLUSIONS: This survey found heterogeneity in hospital resource utilization for noncardiac LVAD procedures. There was a decrease in the use of invasive monitors with increased institutional LVAD volume in both endoscopy and surgical procedures.
