Pressure support ventilation (PSV) usually provides good patient-ventilator synchrony, but asynchrony is sometimes encountered. Double breathing is one form of asynchrony in which the ventilator assists two or more times during a single inspiration of the patient. ⋯ Double breathing during PSV was considered to be closely associated with obstructive or restrictive lung. If the problem arises and cannot be resolved by adjusting ventilatory parameters, the ventilatory mode must be changed.

We investigated vecuronium-induced neuromuscular blockade in patients with continuous epidural lidocaine injection and those without epidural lidocaine. ⋯ Based on our results, we conclude that lidocaine injected continuously into the epidural space potentiates vecuronium-induced neuromuscular block.

We experienced anesthetic management of two cases of amyotrophic lateral sclerosis (ALS). Case 1. A 46-year-old woman underwent emergency operation for ileus. ⋯ During and after the operation, she was in good general condition and had no pain. For the patients with ALS, prolongation of muscle relaxation and residual neuromuscular block effect may cause difficult tracheal extubation and postoperative respiratory complications. We observed carefully the condition of the patients with ALS, and were able to choose the minimum invasive anesthetic methods for each case.

In cases of hydrops foetalis, respiratory management is frequently required after delivery. We experienced 7 anesthetic managements for cesarean section in patients with hydrops foetalis. ⋯ Before surgery, we discussed perioperative and anesthetic management among pediatricians, pediatric surgeons, and obstetricians in a conference. Since the anesthetic drugs used for the cesarean section have great influences on the fetus, the choice of anesthesia should be performed based on fetal conditions.

Randomized Controlled Trial Clinical Trial
[Ilioinguinal/iliohypogastric nerve block for pediatric inguinal herniorrhaphy; evaluation of the dose of ropivacaine].
The aim of this study was to investigate the appropriate dose of ropivacaine in efficacy and safety when administered for ilioinguinal/iliohypogastric nerve block in children undergoing inguinal herniorrhaphy. ⋯ These results suggest that more than 0.9375 mg x kg(-1) of ropivacaine might be recommended to obtain sufficient postoperative analgesia for the ilioinguinal/iliohypogastric nerve block in children undergoing inguinal herniorrhaphy.
