OBJECTIVE To measure exhaled nitric oxide (NO) and compare it with lung function after cardiopulmonary bypass (CPB) in adult patients. Pulmonary dysfunction is sometimes observed after CPB. Impaired production of NO may account for this dysfunction. DESIGN Prospective, single-center, observational study. SETTING University hospital operating room,(More)
We modified the technique for laryngeal mask airway (LMA) insertion in children. This modification involves inserting a two-thirds inflated LMA with its lumen facing laterally toward left and then rotating it 90 degrees clockwise as it passes downwards into position behind the larynx. Then the cuff is inflated fully. We conducted a survey on the use of LMA(More)
BACKGROUND The effects of volatile anesthetics on subtypes of K(+) channels located on pulmonary vessels remain largely unexplored. METHODS To investigate whether or not potassium channels play a role in the effect of volatile anesthetic on pulmonary vessels, isolated and perfused rabbit lungs were divided into four groups (n = 7 each): a control group(More)
To investigate the effect of simultaneous bolus injection of 2% lidocaine 2 ml on preventing the pain on propofol injection, 80 patients were randomly assigned to one of four study groups; Group I received simultaneous bolus injection of 2% lidocaine 2 ml with infusion of propofol; Group II received bolus injection of saline 2 ml, 10 s before the start of(More)
Although it is well-known that 2% lidocaine has an effective action for preventing propofol-induced pain, it has been unclear whether or not lidocaine of the concentration below 2% has the effective action similar to 2% lidocaine. One-hundred and thirty-two patients were randomly assigned to one of the six groups according to concentration and dosage of(More)
with saline before insertion. Anesthesia was induced by 3.0%–5.0% sevoflurane with 50% nitrous oxide in oxygen. Before insertion of the LMA, anesthesia was maintained with 3.0% end-tidal sevoflurane concentration in oxygen for 5min. No muscle relaxants were used. Another anesthesiologist assisted the performer to open the patient’s mouth by pulling down the(More)
A circadian rhythm of the susceptibility to thiamylal was evaluated in 30 patients. They were divided into two groups; 15 patients were induced around 9 AM (Morning-group) and the rest were in the early afternoon (Afternoon-group). The induction was performed by intravenous administration of thiamylal sodium. Parameters measured were the time and doses of(More)
A 5 year-old boy with myotonic dystrophy was anesthetized with isoflurane for bilateral orchiopexy. Intubation was easily done without muscle relaxants, following slow induction using isoflurane, nitrous oxide and oxygen. Myotonia was not observed perioperatively and postoperative course was uneventful. It is concluded that isoflurane is an anesthetic of(More)
The chemiluminescent emission reaction dependence on the activity of phagocytosis is well known. However, this method is not used to diagnostically in clinical assessment because the relationship between phagocytizing activity and chemiluminescent intensity has not been clearly established. Therefore, we attempted to analyze quantitatively the(More)
