Background: Both ketamine and priming may accelerate the onset time of neuromuscular blocking agents. We investigate the effect of low dose ketamine and cisatracurium priming on the intubating condition and onset time of cisatracurium. Methods: After Institutional Review Board approval, 120 consecutive patients undergoing general anesthesia were randomly assigned to one of 4 groups. All patients were injected one of normal saline (group C), cisatracurium 0.01 mg/kg (group P), ketamine 0.5 mg/kg (group K) and combination of cisatracurium 0.01 mg/kg, and ketamine 0.5 mg/kg (group PK) diluted into a 5 ml solution, followed 3 minutes later by cisatracurium 0.15 mg/kg in group C and K, and 0.14 mg/kg cisatracurium in priming group. Onset time was recorded the electromyographical responses using single twitch and intubating conditions were evaluated at 60 seconds after cisatracurium administration. Results: The mean onset time was most significantly accelerated in Group PK and was also significantly more accelerated in Group P and K compared with Group C (P < 0.008). It was 112.7 ± 13.2, 91.4 ± 17.9, 84.9 ± 12.7 and 76.4 ± 8.3 seconds in Group C, P, K, and PK, respectively. Intubating conditions were significantly improved in Group P, K and PK than Group C (P < 0.008). Especially, Group PK showed most significant improvement of intubating conditions. Conclusions: The combination of the low dose ketamine and cisatracurium priming accelerated the onset time and was improved the intubating conditions.

Pneumonia due to aspiration of povidine iodine after induction of general anesthesia -A case report-
안태훈,안병량 대한마취통증의학회 2011 Korean Journal of Anesthesiology Vol.61 No.3
Aspiration pneumonia is usually caused by aspiration of gastric contents during anesthesia. It causes severe pulmonary complications. Povidone iodine was used widely as an oral antiseptic. Although povidone iodine is thought to be a safe and effective antiseptic, severe complications from its aspiration may occur. We present a case of pneumonia secondary to aspiration of povidone iodine in a 16 year old female patient who underwent orofacial surgery. Aspiration pneumonia must be treated immediately. Mechanical ventilation with PEEP and periodical bronchial toilet with fiberoptic bronchoscopy were carried in the operating room and ICU. Bronchodilators,antibiotics, steroids and diuretics were also used to treat pneumonia. The patient was treated successfully without any complication.
