Brief Summary:

A prospective study designed to evaluate changes in tissue and cerebral oxygenation before and following administration of blood for patients undergoing spinal surgery.

Red blood transfusions (autologous and allogeneic) are indicated to improve oxygen delivery to the tissues and hence tissue oxygenation. Despite the presumed efficacy, there are limited data to demonstrate changes in tissue oxygenation with the administration of blood. Furthermore, the administration of both autologous blood from cell saver and allogeneic blood can be associated with both acute and long-term deleterious physiologic effects which may impact the perioperative course. As such, data are needed to clearly delineate the benefits of transfusion during the perioperative period.

Condition or disease Intervention/treatment
Idiopathic Scoliosis Transfusion Reaction Other: Cerebral Oxygenation Changes

Detailed Description:
This prospective study will include patients presenting for spinal surgery. There will be no change in the anesthetic or perioperative care of these patients. Per our usual clinical routine, cell saver will be used intraoperatively to limit the need for allogeneic blood. Tissue and cerebral oxygenation will be monitored using near infrared spectroscopy (NIRS). The device is applied non-invasively like pulse oximetry to a muscle bed (usually the deltoid) and the forehead to measure tissue oxygenation. These devices are used routinely in the operating room and the cardiothoracic intensive care unit. Although not used on every major orthopedic procedure, these devices are routinely used in various high risk clinical scenarios. As clinically indicated, cell saver blood (autologous) or allogeneic blood will be administered. During this time, tissue and cerebral oxygenation will be recorded every 5 minutes starting 10 minutes before the transfusion and continued for 30 minutes following the transfusion.

Intervention Details:
  • Other: Cerebral Oxygenation Changes
    Monitor cerebral oxygenation changes in patients receiving blood transfusions who are undergoing spinal fusion surgery.

Primary Outcome Measures :
  1. Cerebral Oxygenation Changes [ Time Frame: Intraoperative measure ]
    To evaluate changes in tissue and cerebral oxygenation during the administration of autologous or allogeneic blood during spinal surgery.

Secondary Outcome Measures :
  1. Oxygenation Changes in Autologous versus Allogeneic Blood Transfusions [ Time Frame: Intraoperative measure ]
    To determine if there are differences in the changes in tissue and cerebral oxygenation with autologous compared to allogeneic blood.
