Swyer-James syndrome (SJS) shows the constellation of radiographic findings of a small, hyper lucent lung, with an ipsilateral, diminished peripheral vasculature, air trapping, and a lack of peripheral fill on bronchography. We report a case of 70-year-old woman with SJS who underwent pulmonary resection of the normal side lung for lung tumor. Because of this syndrome, we could predict the hypoxia during one-lung ventilation. ⋯ As we could not improve the hypoxia in spite of increasing FI(O2), O2 administration to the operating side lung was started. Sp(O2) recovered after O2 administration. For anesthetic management of a patient with SJS in the normal-side-lung, it is essential to prevent the hypoxia during one-lung ventilation.

A 60-year-old morbidly obese woman (150 cm, 112 kg, BMI 49.8) underwent total knee replacement under general anesthesia combined with sciatic nerve block and continuous femoral nerve block. Following induction of general anesthesia and tracheal intubation, the sciatic nerve was blocked using the popliteal approach with the patient in the supine position. Then the femoral nerve block was performed, followed by perineural catheter placement for postoperative continuous local anesthetic infusion. ⋯ Postoperatively 0.15% ropivacaine was infused at the rate of 5 ml x hr(-1) for 60 hours through the femoral catheter, which provided satisfactory pain relief in combination with scheduled loxoprofen administration. No block-related complications were noted. Our experience suggests that the ultrasound-guided technique may prove useful to facilitate safe and accurate block when technical difficulties are anticipated with anatomic landmark-based approaches.

Comparative Study
[Comparison of thoracoscopic and open repair of esophageal atresia with tracheoesophageal fistula].
With the increasing use of endoscopic surgery in children, several papers report the comparison between the thoracoscopic and open repair of the neonatal esophageal atresia with tracheoesophageal fistula (EA/TEF). Most of them focus on the duration and outcome of the surgery with few focusing on the neonatal tolerance to the thoracoscopic procedure and intraoperative anesthetic management. ⋯ Hypercapnia and acidosis were severer in thoracoscopy group. Careful perioperative adjustment of inspired oxygen fraction and ventilator setting is required.

Comparative Study
[Nasotracheal intubation using GlideScope videolaryngoscope or Macintosh laryngoscope by novice laryngoscopists].
We compared the performance of GlideScope videolaryngoscope with that of the conventional Macintosh laryngoscope for nasotracheal intubation by non-anesthesia residents. ⋯ The unobstructed view of the glottic opening on the video monitor helped the laryngoscopist performing the nasal endotracheal intubation while an assistant provided laryngeal manipulation to improve the coordinated effort. GlideScope seems to facilitate nasotracheal intubation for individuals training in airway management.

We report anesthetic management of a 6-month-old boy with Menkes disease who underwent three surgeries for vesicoureteral reflux, rupture of the bladder diverticulum, inguinal hernia, and gastroesophageal reflux. Menkes disease is a rare sex-linked disorder of copper absorption and metabolism. Anesthetic management of such patients is rather challenging because of high incidence of seizures, gastroesophageal reflux with the risk of aspiration, hypothermia, airway and vascular complications. ⋯ It was especially difficult to establish intravenous and invasive blood pressure lines because of tortuous blood vessels in this patient. We conclude that in patients with Menkes disease scheduled for surgery intravenous access should be established before the induction of general anesthesia. The necessity of invasive blood pressure monitoring should be also carefully considered beforehand.
