To determine the minimum alveolar concentration (MAC) of sevoflurane required for 50% blockade of the adrenergic response (BAR) to surgical incision in patients treated with neoadjuvant chemotherapy prior to radical gastrectomy. ⋯ Neoadjuvant chemotherapy reduced the MAC-BAR value of sevoflurane in gastric cancer patients by enhancing the inhibitory effect of sevoflurane on the stress response.

This study aims to compare the hemodynamic responses to endotracheal intubation performed with direct and video laryngoscope in patients scheduled for cardiac surgery and to assess the airway and laryngoscopic characteristics. One hundred ten patients were equally allocated to either direct Macintosh laryngoscope (n = 55) or indirect Macintosh C-MAC video laryngoscope (n = 55). Systolic, diastolic, and mean arterial pressure, and heart rate were recorded prior to induction anesthesia, and immediately and two minutes after intubation. ⋯ The C-MAC video laryngoscope group had better laryngoscopic view as assessed by Cormack-Lehane and percentage of glottic view, and a longer intubation time. Number of attempts, external pressure, use of stylet, and difficult intubation parameters were similar. Endotracheal intubation performed with direct Macintosh laryngoscope or indirect Macintosh C-MAC video laryngoscope causes similar and stable hemodynamic responses.

Fentanyl-induced cough is a common phenomenon during anesthesia induction. Magnesium sulphate (MgSO4) is reported to have a powerful relaxation of airway smooth muscle. This study is to investigate the effects of prophylactic MgSO4 on the incidence and severity of fentanyl-induced cough. ⋯ Compared with the group I, both the groups II and III had lower incidence of moderate cough (P < 0.05). There were no differences in the hemodynamic data at three timepoints among the three groups. In conclusion, fentanyl-induced cough may be suppressed effectively and safely by prophylactic 30 mg/kg of MgSO4 during anesthetic induction.

To observe intraoperative and postoperative analgesic effect of ultrasound-guided subcostal transversus abdominis plane (TAP) block in gastric cancer patients undergoing open gastrectomy. ⋯ Ultrasound-guided subcostal transversus abdominis plane block has the advantages of accurate localization and high success rate. Clinical application of this technique in open gastrectomy can significantly decrease intraoperative and postoperative dosage of analgesics and exert desirable analgesic effect.

To investigate the clinical utility of dual-source dual-energy CT angiography (DSDECTA) for diagnosing intracranial dural arteriovenous fistula (DAVF). ⋯ Although DSA is the gold standard for DAVF diagnosis, DSDECTA is less invasive and more suitable for revealing the three-dimensional structure of secondary intracranial lesions as well as other DAVF characteristics. Thus, DSDECTA may be a new alternative for noninvasive screening of suspected DAVF patients before interventional embolization and surgical resection.
