Case ReportsCombination of extracorporeal membrane oxygenation and high-frequency oscillatory ventilation saved a child with severe ARDS after pulmonary resection.
We report a case in which a 2-year-old girl who underwent a right middle and lower lung lobectomy for congenital cystic adenomatoid malformation suffered massive bleeding and developed acute respiratory distress syndrome (ARDS) during the operation. She was ventilated with a high level of F(I)O(2) (0.75-1.0), PEEP (10-20 cmH(2)O), and PIP (33-55 cmH(2)O) to maintain SPO(2) (>90%). Following transfer to the ICU, continuous hemodialysis was introduced to reduce excessive blood volume. ⋯ ECMO was successfully weaned on POD 88. The patient required a tracheostomy, but she was able to function without a ventilator on POD 142. Although HFOV has failed to show a mortality benefit in ARDS patients, the unique lung recruitment by HFOV can be a useful therapeutic option for severe ARDS patients in combination with sufficient lung rest produced by ECMO.

Case ReportsAnesthetic management of a patient with congenital diaphragmatic eventration.
Congenital diaphragmatic eventration is uncommon in adults and is caused by paralysis, aplasia or atrophy of the muscular fibers of the diaphragm. It may cause severe dyspnea, orthopnea and hypoxia in adult patients. ⋯ This case report presents the successful anesthetic management of an adult female with congenital diaphragmatic eventration undergoing diagnostic laparoscopy and hysteroscopy using a total intravenous anesthesia technique. Essential steps to prevent any rise in intrathoracic and intra-abdominal pressures along with care to minimize intragastric volume were taken.

Human brain activity associated with painful mechanical stimulation to muscle and bone.
The purpose of this study was to elucidate the central processing of painful mechanical stimulation to muscle and bone by measuring blood oxygen level-dependent signal changes using functional magnetic resonance imaging (fMRI). ⋯ The putamen and caudate nucleus may have a more significant role in brain processing of muscle pain compared with bone pain.

Ultrasound-guided medial mid-thigh approach to sciatic nerve block with a patient in a supine position.
We report the use of a 'medial mid-thigh approach (medial approach),' a new approach for performing ultrasound-guided sciatic nerve blockade (SNB) with patients in a supine position. Fifty-four patients undergoing knee surgery under general anesthesia and a combined femoral nerve block (FNB) and SNB were included in the study. After FNB, an ultrasound-guided medial approach was used to perform the SNB. ⋯ The block was successful in all patients, and the mean duration of the sensory and motor blockade was 11.9 and 8.2 h, respectively. In this study, the medial approach was highly successful and easy to perform. As performing a simultaneous FNB and SNB with patients in a supine position has several potential advantages, future studies should compare this approach with other more proximal approaches for performing SNB.

Case ReportsA case of serious laryngeal edema unpredictably detected during laryngoscopy for orotracheal intubation following induction of anesthesia.
We report a case of unpredictable and serious laryngeal edema probably caused by preoperative esophagogastroduodenoscopy (EGD). A 54-year-old man with type 2 diabetes mellitus was scheduled to undergo coronary artery bypass grafting (CABG). Two days before surgery, EGD was performed to explore the cause of occult bleeding, resulting in a slightly sore throat and an increased white blood cell count (18,300/μl). ⋯ Treatment consisted of intravenous cefazolin (2 g/day) and hydrocortisone (300 mg/day tapered to 100 mg/day) for 9 consecutive days. Consequently, the patient recovered gradually from the inflammation and underwent CABG as scheduled 28 days later. Anesthesiologists should be aware that EGD performed just before anesthesia could unpredictably cause acute epiglottitis, especially in immunocompromised patients, such as those with diabetes.
