[Fentanyl shows different effects by administration routes on bispectral index during spinal anesthesia in patients undergoing cesarean section].

Background: Spinal anesthesia using a local anesthetic with fentanyl has been reported to induce sedation. We previously reported that the bispectral index (BIS) value was significantly decreased by spinal anesthesia using only bupivacaine and fetanyl after cesarean delivery. In the present study, we studied the effect of different fentanyl administration routes on BIS values during spinal anesthesia for cesarean section.

Pneumothorax after pneumonectomy: surgery with successful double lobe ventilation.

Contralateral pneumothorax is potentially lethal in patients who have undergone pneumonectomy. There are few reports about the diagnosis and treatment of this situation. This is a report of our experience with selective lobar ventilation of the middle and lower lobes using a guidewire and a bronchial blocker in the right upper bronchus of a patient who had previously undergone left pneumonectomy.

[Anesthetic management of pneumonorrhaphy for one-lung patient].

Selective immobilisation of the lobes of the lungs with a bronchial blocker is sometimes a challenge for anesthesiologists. A pneumonorrhaphy was planned in a patient who had had undergone left pneumectomy, and selective immobilisation of the right upper lobe was requested. The initial attempt to place the cuff of a bronchial blocker was unsuccessful.

[Appropriate dose of isobaric bupivacaine with fentanyl in spinal anesthesia for cesarean section].

Background: Spinal anesthesia combined with fentanyl is commonly used for cesarean section. We studied the appropriate dose of isobaric bupivacaine for spinal anesthesia when combined with a fixed dose of 20 microg fentanyl.

Methods: Forty-seven women scheduled for cesarean section were allocated into four-groups according to the dose of 0.

[Undetachable connection between a reinforced endotracheal tube and L connector].

We anesthesiologists sometimes encounter a situation where we difficulty detaching an L connector from an endotracheal tube. However, to our knowledge, there is no paper wich describes complete inability of detaching the connector from the tube. A 33-year-old female patient was scheduled for jaw joint arthroplasty and manipulation of synarthrophysis after the previous intermaxillary fixation.

Pentobarbital inhibits ketamine-induced dopamine release in the rat nucleus accumbens: a microdialysis study.

Unlabelled: Dopamine release in the nucleus accumbens (NAC) plays a crucial role in the actions of various psychotropic and addictive drugs. Ketamine and barbiturates have psychotropic effects and addictive properties, but barbiturates prevent ketamine's psychotomimetic effects. We investigated the effects of ketamine and pentobarbital on dopamine release in the NAC.
