Mononostril endoscopic endonasal approach for pituitary surgery.

Background: Most surgical teams currently consider that endoscopy has become the "gold standard" technique for the transsphenoidal approach to pituitary surgery. Pituitary adenomas are commonly benign tumours and should benefit from the least invasive approach.

Method: In Foch Hospital, from 2006 to 2020, 2835 patients with pituitary adenomas were treated with a mononostril endoscopic endonasal approach.

Impact of the modality of mechanical ventilation on bleeding during pituitary surgery: A single blinded randomized trial.

Background: Bleeding modifies the surgeon's view of the field during transsphenoidal endoscopic pituitary surgery. Since ventilation can alter venous return, we compared the effect of volume-controlled ventilation (VCV) and pressure-controlled ventilation (PCV) on intraoperative bleeding.

Methods: Eighty-six patients were randomized to VCV or PCV in this single blinded study; comparisons concerned 42 in the PCV group and 43 in the VCV group.

BIS values during resuscitation: the role of the suppression ratio (case report).

We report a case during which it was simultaneously recorded usual Bispectral Index (BIS) values and elevated suppression ratio (SR) during resuscitation maneuvers. A 52-year-old woman, scheduled for a suspension laryngoscopy, required cardio-pulmonary resuscitation due to an anaphylactic shock secondary to the administration of succinylcholine. Post-crisis analysis of the BIS trace showed both BIS numbers consistent with an adequate level hypnosis and an increase in SR.
