Comparison of effect-site concentration of remifentanil for tracheal intubation with the lightwand and laryngoscopy during propofol target-controlled infusion.
Target-controlled infusion (TCI) of propofol and remifentanil can provide satisfactory intubating conditions without a neuromuscular blocking agent. We compared the effect-site concentration of remifentanil required for intubation with the lightwand and the Macintosh laryngoscope during propofol TCI without a neuromuscular blocking agent in adult patients. ⋯ The effect-site concentration of remifentanil for acceptable intubation with the lightwand and Macintosh laryngoscope in 50% of adults did not differ during propofol TCI without a neuromuscular blocking agent.

Postoperative nausea and vomiting after endoscopic thyroidectomy: total intravenous vs. balanced anesthesia.
Endoscopic thyroidectomy was recently introduced and has been rapidly accepted by surgeons and patients. The present study was conducted to estimate and compare the incidences of postoperative nausea and vomiting (PONV) after endoscopic thyroidectomy using two different anesthetic methods: sevoflurane based balanced anesthesia; total intravenous anesthesia (TIVA). ⋯ After endoscopic thyroidectomy, total intravenous anesthesia with propofol-remifentanil is associated with less PONV during the early postoperative period (0-6 hours) than sevoflurane based balanced anesthesia.

Intravenous dexamethasone pretreatment reduces remifentanil induced cough.
Remifentanil infusion is commonly used for general anesthesia but reflex cough can occur after an intravenous (IV) infusion. This study was designed to examine the effect of IV-dexamethasone on remifentanil-induced cough (RIC). ⋯ Pretreatment with dexamethasone after IV administration was effective in suppressing the reflex cough induced by remifentanil infusion.

Effects of 10% lidocaine spray on arterial pressure increase due to suspension laryngoscopy and cough during extubation.
It is well known that suspension laryngoscopy (SL) produces marked hemodynamic changes. Coughing during extubation sometimes causes adverse clinical problems. We investigated whether 10% lidocaine spray could attenuate hemodynamic stress responses due to SL and reduce coughing incidence during extubation. ⋯ Preoperative laryngeal and intratracheal spraying with 1.5 mg/kg of 10% lidocaine spray is effective for attenuation of arterial pressure increase to SL and suppression of coughing during extubation.

Effect-site concentration of remifentanil for blunting hemodynamic responses to tracheal intubation using light wand during target controlled infusion-total intravenous anesthesia.
Transillumination using a light wand is an alternative type of laryngoscope used for tracheal intubation. There is little information available on the effect-site concentration of remifentanil required to control hemodynamic changes induced by tracheal intubation using the transillumination method during total IV anesthesia. We therefore conducted this study to determine the effect-site concentration of remifentanil blunting hemodynamic responses after tracheal intubation in patients receiving propofol anesthesia. ⋯ This study shows that effect-site concentrations of remifentanil of 2.94 ng/ml is effective in blunting sympathetic responses to tracheal intubation in 50% of patients with normal airway anatomy when combined with a target controlled infusion of propofol (4 µg/ml).
