Factors That Correlate With the Decision to Delay Extubation After Multilevel Prone Spine Surgery.
Multilevel spinal decompressions and fusions often require long anesthetic and operative times, which may result in airway edema and prolonged postoperative intubation. Delayed extubation can lead to bronchopulmonary infections and other complications. This study analyzed which factors correlated with the decision to delay extubation after multilevel spine surgery. ⋯ Our study found that age, ASA class, procedure duration, extent of surgery, and total crystalloid and blood volume administered correlate with the decision to delay extubation in multilevel prone spine surgery. It also finds that the time the case ends is an independent variable that correlates with the decision not to extubate at the end of a long multilevel spinal surgery. The incidence of postoperative pneumonia is higher in patients who had a delayed extubation after surgery.

Effect of Mild Hypothermic Cardiopulmonary Bypass on the Amplitude of Somatosensory-evoked Potentials.
Several neurophysiological techniques are used to intraoperatively assess cerebral functioning during surgery and intensive care, but the introduction of hypothermia as a means of intraoperative neuroprotection has brought their reliability into question. The present study aimed to evaluate the effect of mild hypothermia on somatosensory-evoked potentials' (SSEPs) amplitude and latency in a cohort of cardiopulmonary bypass (CPB) patients as the temperature reached the steady-state. ⋯ The increased amplitude in particularly of cortical SSEPs (N20/P25), detected specifically during steady-state hypothermia, seems to support the clinical utility of this methodology in monitoring the brain function not only during cardiac surgery with CPB, but also in other settings like therapeutic hypothermia procedures in an intensive care unit.
