Prognostic factors associated with mortality in patients undergoing emergency surgery for abdominal aortic aneurysms.
Surgical mortality rates following emergency surgery for ruptured abdominal aortic aneurysms (AAAs) remain high. This study investigated the mortality rate and identified prognostic factors affecting mortality in patients undergoing emergency repair of AAAs in our hospital. ⋯ The authors clarified that certain features such as age, persistent preoperative shock, and greater amounts of transfusion associated with greater blood loss and anemia were factors affecting the mortality in patients undergoing emergency surgery for AAAs. It might be of great importance to correct preoperative shock and anemia caused by massive bleeding before the onset of hemodynamic deterioration.

Backboard insertion in the operating table increases chest compression depth: a manikin study.
The quality of chest compression (CC) is influenced by the surface supporting the patient. The present study compared chest compression depth with and without a rigid backboard on an operating table with a pressure-distributing mattress. We hypothesized that the presence of a backboard would result in an increased depth of chest compression on the operating table with a pressure-distributing mattress. ⋯ Mean chest compression depth increased from 4.9 ± 0.4 to 5.4 ± 0.3 mm (P < 0.0001) when a backboard was present. Mean proportion of compressions >50 mm increased significantly with the presence of a backboard (53.6% ± 32.3%-81.8% ± 15.0%, P < 0.0001). Applying a backboard significantly increased CC depth during cardiopulmonary resuscitation of a manikin model on an operating table with a pressure-distributing mattress.

Case ReportsMultilevel nerve stimulator-guided paravertebral block as a sole anesthetic technique for breast cancer surgery in morbidly obese patients.
In this case series, we present the effectiveness of multilevel nerve stimulator-guided paravertebral block (PVB) technique in obese women of body mass index ≥30 kg/m(2) undergoing breast cancer surgery with or without axillary dissection. Twenty-six obese women were included in this case series. Block classification, hemodynamics and complication rate, postoperative nausea and vomiting, postoperative analgesic consumption, post-anesthesia care unit (PACU) stay, and hospital stay were recorded. ⋯ Confirmation of the landmark was established from the initial attempt in 61.5%. Surgical PVB was achieved in 76.9% of the patients; the failure rate of the technique was 11.5%. This case series suggested that the multilevel nerve stimulator-guided PVB may be an effective technique for obese patients undergoing breast cancer surgery, although further studies are needed to compare PVB and general anesthesia.

Randomized Controlled TrialFlurbiprofen axetil enhances analgesic effect of fentanyl associated with increase in β-endorphin levels.
To examine the analgesic effect of preoperative administration of flurbiprofen axetil and that of postoperative administration of a combination of flurbiprofen axetil and fentanyl, as well as perioperative plasma β-endorphin (β-EP) levels in patients undergoing esophagectomy. ⋯ These results show that flurbiprofen axetil enhances the analgesic effect of fentanyl associated with increase in β-EP levels.
