Influence of carbon dioxide insufflation of the neck on intraocular pressure during robot-assisted endoscopic thyroidectomy: a comparison with open thyroidectomy.

Background: Increased intraocular pressure (IOP) during surgery can result in serious ophthalmic complications. We hypothesized that carbon dioxide (CO₂) insufflation of the neck during endoscopic thyroidectomy would constrict the jugular veins mechanically, causing elevated venous pressure and thus elevated IOP. We compared IOP changes at each step of open thyroidectomy (OT) versus robot-assisted endoscopic thyroidectomy (RET) METHODS: Perioperatively, IOP was measured at six time points in patients undergoing OT (n = 18) or RET with CO₂ insufflation (n = 19).

Anesthetic management for a pediatric patient with joubert syndrome: A case report.

Joubert syndrome is a rare autosomal recessive condition in which there is complete or partial agenesis of the cerebellar vermis. The clinical features are hypotonia, ataxia, mental retardation, abnormal ocular movements, typical facial features and episodic tachypnea with alternating apnea. The abnormal respiratory pattern and hypotonia may be exacerbated by anesthetics, and especially, the apneic episodes may be prolonged by administering opioids.

Effect of fentanyl on hemodynamic changes connected with a thigh tourniquet during knee arthroscopic surgery.

Background: The use of a tourniquet can produce pain and increase in blood pressure. It is known that fentanyl reduces central sensitization, however its effect on blood pressure increase due to tourniquet is unknown. So we investigated the effect of fentanyl on tourniquet-induced changes of mean arterial blood pressure (MBP), heart rate (HR), and cardiac index (CI).

Lidocaine does not prevent bispectral index increases in response to endotracheal intubation.

We investigated the effect of IV lidocaine on the hemodynamic and bispectral index responses to induction of general anesthesia and endotracheal intubation. Forty patients (ASA I) were randomly allocated into 2 groups of 20 to receive normal saline or lidocaine 1.5 mg/kg IV 30 s after induction.
