Terumo's Surshield Surflow II i.v. catheter automatically engages a stainless steel clip to shield its needle tip when the needle goes out from the catheter hub. However, in our experience the safety clip of Surshield Surflow II remains in the catheter hub in a high proportion of cases when the catheter hub is held with a pair of forceps. ⋯ Another factor is the loose attachment of the safety clip to the needle tip. To prevent needle stick injury, further improvement of safety i.v. catheters is necessary to lead their increased use.

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.

A 9-year-old boy was scheduled for excision of tracheal granuloma which had developed at the tip of a tracheostomy tube. Instead of a tracheostomy tube, a 4 mm ID tracheal tube was inserted via the tracheostomy beyond the tracheal constriction because of rapid development of respiratory failure. General anesthesia was induced and maintained with sevoflurane and oxygen via the tube, and a size 2.5 laryngeal mask airway (LMA) was inserted without muscle relaxant. ⋯ After sealing the tracheostomy, he could breath spontaneously through the LMA. During the excision of tracheal granuloma by holmium:YAG laser, fiberoptic observation was continued via the LMA, and the procedure was performed without any complication. We conclude that the tracheal stenosis can be managed using the LMA, continuous fiberoptic monitoring and additional option of keeping spontaneous ventilation.

Case Reports
[Anesthetic management for cesarean section in a patient with corrected transposition of great arteries].
A 20-year-old woman with corrected transposition of great arteries (height 163 cm, weight 69 kg) was scheduled for elective cesarean section at 36 weeks of gestation. Since her mitral insufficiency had deteriorated during pregnancy, she developed dyspnea and lower cardiac function. We decided to perform general anesthesia for her cesarean section. ⋯ No cardiac events were observed during surgery. The postoperative course was uneventful, and the patient was discharged from the hospital on the 10th postoperative day. Swan-Ganz catheter was useful for the evaluation of cardiac function and for anesthetic management.
