Case Reports
Life-threatening anaphylactic shock due to chlorhexidine on the central venous catheter: a case series.
In this article, we report two life-threatening anaphylactic shocks by an antiseptic coated central venous catheter (CVC) within a 6-month period in our cancer center. Anaphylactic shock was preceded immediately after insertion of a central venous catheter (CVC) coated with silver sulphadiazine and chlorhexidine acetate (Blue FlexTip(®) ARROWg(+)ard Blue(®), 14Ga, Arrow International, Inc. ⋯ Though antiseptic coated CVC anaphylaxis has been reported in Japan, Europe and America, to our knowledge, this is first reported in China. We present these rare cases to remind clinicians about hypersensitivity to chlorhexidine that could potentially be life-threatening.

To compare the different outcomes of dexmedetomidine (Dex) vs. propofol combined with sevoflurane in children's laparoscopic surgery by noninvasive continuous cardiac output monitoring (NICOM). ⋯ Compared with propofol, the combination of Dex in children undergoing laparoscopic surgery shows better inhibition on HR.

This study is to test the effectiveness of fiber-optic-guided endotracheal suction catheter (visual sputum suctioning system or VSSS) in dog models. ⋯ Visual sputum suctioning system collected more sputum and caused less tracheal mucosa damage than conventional suctioning.

Previous studies demonstrated that systemic administration of lidocaine could induce central nervous toxicities, including behavioral convulsion as well as cognitive and cellular injury. Ketamine, a general anesthetic, is commonly used as an adjuvant in regional anesthesia with combination of lidocaine. The present was designed to investigate the effects of ketamine in central nervous toxicities of lidocaine. ⋯ We conclude that both pre- and/or post-administration of ketamine could improve lidocaine induced convulsive behaviors. However, cognitive functions and pathology of neurons of these rats are further impaired, compared to the rats without ketamine. This result indicates that ketamine combined with lidocaine might be risky in regional anesthesia.

To observe the change of PVI after thoracic epidural block on the basis of general anesthesia. ⋯ PVI can be used as a noninvasive indictor to monitor volume change after thoracic epidural block on the basis of general anesthesia.
