Comparative StudyThe Effect of Position on PaCO2 and PETCO2 in Patients Undergoing Cervical Spine Surgery in Supine and Prone Position.
As per American Society of Anesthesiologists guidelines, continuous monitoring of end tidal carbon dioxide (PETCO2) is recommended as standard II basics of anesthetic monitoring especially to ensure adequate ventilation during all anesthetics. Continuous monitoring of PETCO2 can also be used as a guide to maintain the partial pressure of carbon dioxide in arterial blood (PaCO2) to desired level during the surgery. ⋯ PETCO2 can be used as a reliable guide to estimate PaCO2 during cervical spine procedures in prone position.

Perianesthetic Management of Patients With Thyroid-Stimulating Hormone-Secreting Pituitary Adenomas.
Thyroid-stimulating hormone (TSH)-secreting pituitary adenomas are a rare cause of secondary hyperthyroidism. Anesthetic management of these patients has not been formally described in the literature. ⋯ Patients having resection of TSH-secreting pituitary adenomas can present in any thyroid state. An awareness of risks and potential complications in patients with TSH-secreting adenomas can help tailor perioperative care.

Effects of Prone Position and Positive End-Expiratory Pressure on Noninvasive Estimators of ICP: A Pilot Study.
Prone positioning and positive end-expiratory pressure can improve pulmonary gas exchange and respiratory mechanics. However, they may be associated with the development of intracranial hypertension. Intracranial pressure (ICP) can be noninvasively estimated from the sonographic measurement of the optic nerve sheath diameter (ONSD) and from the transcranial Doppler analysis of the pulsatility (ICPPI) and the diastolic component (ICPFVd) of the velocity waveform. ⋯ Noninvasive ICP estimation may be useful in patients at risk of developing intracranial hypertension who require prone positioning.
