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 ReportsDexmedetomidine as sole agent for awake fiberoptic intubation in a patient with local anesthetic allergy.
A series of case reports acknowledges the efficacy of dexmedetomidine as a sole sedative for awake intubations in managing a critical airway. However, most case reports documented in the literature used topicalization of the oropharynx either via nebulized lidocaine or the spray-as-you-go technique with either 2% or 4% lidocaine spray to achieve successful intubation. ⋯ The ability of dexmedetomidine to act as a sedative, anxiolytic, analgesic, and antisialagogue without causing respiratory depression is promising to the field of anesthesiology. Additional studies are needed to elucidate its potential role as the sole agent for awake fiberoptic intubation.

Evaluation of estimation of physiologic ability and surgical stress to predict in-hospital mortality in cardiac surgery.
Prediction of postoperative risk in cardiac surgery is important for cardiac surgeons and anesthesiologists. We generated a prediction rule for elective digestive surgery, designated as Estimation of Physiologic Ability and Surgical Stress (E-PASS). This study was undertaken to evaluate the accuracy of E-PASS in predicting postoperative risk in cardiac surgery. ⋯ E-PASS may accurately predict postoperative risk in cardiac surgery. Because the variables are different between cardiac-specific models and E-PASS, patients' risks can be double-checked by cardiac surgeons using cardiac-specific models and by anesthesiologists using E-PASS.

The quality of defibrillation performance among students of the University of Medical Sciences.
The major objective was to assess the time period from a witnessed ventricular fibrillation (VF) to the first defibrillation (DEF) in a simulated manikin scenario, while the minor objective was to analyze the most common errors that occurred during DEF and the maintenance of 2-min intervals during resuscitation. We examined 210 students (medical faculty students, MF; and paramedic faculty students, PF) who had to treat a patient with VF. In the study we used the Laerdal(®) Training Manikin and the Zoll M Series(®) defibrillator. ⋯ The problems observed during the study were technical and educational. We concluded that the option "Monitor" should be removed from the equipment because it seems to be redundant. The teaching problems were a lack of constant ECG monitoring, incorrect handling of the defibrillator, and not keeping to 2-min loops of CPR.

Case ReportsIntrathecal neurolytic block in a patient with refractory cancer pain.
We report the successful treatment of refractory cancer pain by bilateral intrathecal neurolysis using phenol-glycerol. A 60-year-old man had recurrent sigmoid cancer and metastases to the lumbar (L4-5) and sacral bones. He complained of refractory pain in the lower back and lower extremities despite high-dose opioid treatment based on the WHO ladder. ⋯ His analgesia was greatly improved and high-dose intravenous opioid was retitrated and ceased. He remained comfortable and lucid at home for 2 months, until 2 days before his death at hospital. Intrathecal neurolytic block may be appropriate for some patients suffering from refractory pain that is resistant to conventional opioid analgesic treatment.
