Effect of ketamine pretreatment for anaesthesia in patients undergoing percutaneous transluminal balloon angioplasty with continuous remifentanil infusion.
An appropriate level of sedation and pharmacological assist are essential during percutaneous transluminal balloon angioplasty (PTA). Ketamine provides good analgesia while preserving airway patency, ventilation, and cardiovascular stability with an opioid sparing effect suggesting that it would be ideal in combination with remifentanil and midazolam in spontaneously breathing patients. We evaluated the effect of a small dose of ketamine added to midazolam and remifentanil on analgesia/sedation for PTA procedures. ⋯ A small dose of ketamine as an adjunct sedative to the combination of midazolam and remifentanil produced a better quality of sedation and analgesia than without ketamine and provided stable respiration without cardiopulmonary deterioration.

Reduction of propofol injection pain by utilizing the gate control theory.
Propofol is the most commonly using intravenous hypnotic for the induction and maintenance of general anesthesia. However, pain on propofol injection is a well known adverse event. Currently, acute and chronic pain can be controlled by utilizing the "gate control" theory. ⋯ Light touch and rubbing reduced pain, although while, they did not reduce the incidence of pain, they reduced the intensity of pain. This method might be considered as an alternative to other treatments but may be contraindicated for use with other drugs.

The antagonistic effect of neostigmine on rocuronium-, clindamycin-, or both-induced neuromuscular blocking in the rat phrenic nerve-hemidiaphragm.
Neostigmine augments clindamycin-induced neuromuscular block and antagonizes rocuronium-induced neuromuscular block; however, it remains unclear whether neostigmine enhances the neuromuscular blocking (NMB) that is caused by combinations of rocuronium and clindamycin. The intent of this study was to determine whether neostigmine potentiates the muscle relaxation that is induced by combinations of rocuronium and clindamycin and to estimate whether both clindamycin and rocuronium have synergistic actions on NMB. ⋯ Neostigmine may partially antagonize the neuromuscular block that is induced by a combination of clindamycin and rocuronium. Clinicians are advised to be aware that clindamycin synergistically increases the degree of rocuronium-induced neuromuscular block, even when neostigmine is present.

The clinical effective dose of alfentanil for suppressing cough during emergence from desflurane anesthesia.
The administration of short-acting opioids before emergence is useful for preventing emergence cough induced by an endotracheal tube. This study examined the clinically effective dose of alfentanil for suppressing cough during emergence from desflurane anesthesia. ⋯ The ED(95) of alfentanil for suppressing emergence cough was 14.0 µg/kg. A single bolus administration of alfentanil during emergence from anesthesia was useful for suppressing emergence cough.

Effect of isoflurane versus propofol-remifentanil anesthesia on neuromuscular blockade and hemodynamic responses by cisatracurium bolus injection.
Inhalational anesthetics potentiate nondepolarizing muscle relaxants. Cisatracurium is a recently introduced neuromuscular blocker in Korea. We studied the effect of inhalational anesthesia and total intravenous anesthesia (TIVA) on neuromuscular blockades and hemodynamic responses by cisatracurium bolus injection. ⋯ Onset time was similar between isoflurane and propofol-remifentanil anesthesia. Clinical duration of action was significantly longer in isoflurane anesthesia. SBP and DBP immediately before intubation and HR, SBP and DBP 1 and 3 min after tracheal intubation were significantly different between the two groups.
