Multicenter Study Observational StudyClinical utility of preoperative screening with STOP-Bang questionnaire in elective surgery.
Obstructive sleep apnea (OSA) is a common disease which increases the risk of perioperative complications. The aim of this study is to assess the clinical utility of preoperative screening for OSA in determining the prevalence of patients at high risk of OSA in a surgical population, the incidence of difficult airway management and the incidence of perioperative complications. ⋯ In conclusion, this study demonstrates that the prevalence of high OSA risk patients in the surgical population is high. The increase in the rates of perioperative complications justifies the implementation of perioperative strategies that use the STOP-Bang as a tool for triage.

Randomized Controlled Trial Comparative StudyUltrasound-guided sciatic nerve block: a comparison between four different infragluteal probe and needle alignment approaches.
Our aim was compare onset time of sciatic nerve blockade (SNB) performed distal to the subgluteal fold using four different ultrasound (US)-guided approaches in patients undergoing foot or ankle surgery. ⋯ The LA-IP approach resulted in a rapid onset of SNB and was associated with the best satisfaction for postoperative analgesia in comparison with LA-OP, SA-IP, and SA-OP approaches for patients undergoing foot and ankle surgery.

Cerebral Regional Oxygen Saturation and Serum Neuromarkers for the Prediction of Adverse Neurologic Outcome in Pediatric Cardiac Surgery.
The aim of this study is to determine the utility of non-invasive bedside neuromonitoring, including cerebral regional oxygen saturation (rSO2) measured by near-infrared spectroscopy and serum biomarkers, in identifying children at risk from adverse neurological outcome after heart surgery. ⋯ Bedside determination of cerebral rSO2 may have some utility in identifying children at risk for adverse neurological outcome after heart surgery in children. Additional studies that are sufficiently powered to control for the many covariates in this patient population will be required to fully interrogate this important question. The role of serum neuromarkers in the immediate post-operative period do not appear to be helpful in this question, though more thorough interrogation of delayed periods may ultimately demonstrate some utility in answering this question.

Case ReportsPostsurgical coagulopathy in a hemophilia A patient with inhibitors: efficacy of recombinant factor VIIa.
Perioperative hemostatic management in patients with hemophilia A who develop the coagulation factor VIII (FVIII) inhibitor is challenging, because exogenous FVIII is neutralized, which boosts the inhibitor to provoke postoperative coagulopathy. Recombinant activated factor VII (rFVIIa) has become available for this type of patient, although FVIII is sometimes required. We treated a 56-year-old male patient with hemophilia A with FVIII inhibitor scheduled for total hip arthroplasty (THA) and total knee arthroplasty (TKA). ⋯ The amount of bleeding during TKA was 1,340 ml, while the level of the inhibitor increased to a greater level than that after THA, provoking uncontrollable bleeding. For anesthetic management in hemophilia A patients with FVIII inhibitor, anesthesiologists must pay attention to postoperative coagulopathy, and every effort should be used to minimize exposure to FVIII. Furthermore, when rFVIIa is ineffective, postponement of surgery until rFVIIa regains its efficacy may be beneficial as compared to an operation with FVIII.
