Randomized Controlled Trial Comparative StudyA "new" automated bolus technique for continuous popliteal block: a prospective, randomized comparison with a continuous infusion technique.
We designed the present, prospective, randomized, double-blind study to compare the administration of an automated intermittent bolus dose with a conventional technique of continuous infusion of local anesthetic for postoperative analgesia in continuous popliteal sciatic nerve blockade. ⋯ The present investigation demonstrated that local anesthetic administered by an automated bolus technique provided better postoperative pain relief than a continuous infusion technique for continuous popliteal nerve block after foot surgery.

Randomized Controlled Trial Comparative StudyGum elastic bougie-guided insertion of the ProSeal laryngeal mask airway is superior to the digital and introducer tool techniques in patients with simulated difficult laryngoscopy using a rigid neck collar.
We compared three techniques for insertion of the laryngeal mask airway ProSeal (PLMA) in patients with simulated difficult laryngoscopy using a rigid neck collar. ⋯ The guided insertion technique is more frequently successful than the digital or IT techniques in patients with simulated difficult laryngoscopy using a rigid neck collar.

Use of bulleyaconitine A as an adjuvant for prolonged cutaneous analgesia in the rat.
Bulleyaconitine A (BLA) is an analgesic and antiinflammatory drug isolated from Aconitum plants. BLA has several potential targets, including voltage-gated Na+ channels. We tested whether BLA elicited long-lasting cutaneous analgesia, when co-injected with lidocaine and epinephrine, as a model for prolonged infiltration anesthesia. ⋯ BLA inhibits Nav1.7 and Nav1.8 Na+ currents in a use-dependent manner. Co-injection of BLA at

IV lidocaine (1.5 mg/kg) administered to facilitate endotracheal intubation was associated with transient bronchospasm in a 17-month-old-female with mild intermittent asthma. Immediately after lidocaine administration, the patient developed diffuse bilateral expiratory wheezes and dramatic increases in peak inspiratory pressure. ⋯ This is consistent with recent clinical studies suggesting that IV lidocaine may cause airway narrowing in asthmatics. Practitioners should be aware of this potential complication.

An instrument designed for faculty supervision evaluation by anesthesia residents and its psychometric properties.
We aimed 1) to develop a valid and reliable instrument for faculty supervision evaluation by anesthesia residents and 2) to disclose the sources of error in residents' ratings. ⋯ The nine-item instrument produced valid and reliable measures of faculty supervision. However, a significant amount of halo effect biased such measures. G-studies may help identify the type and magnitude of rater biases affecting resident-generated faculty supervision evaluations, and can be useful for interpreting their results, especially if personnel decisions (e.g., tenure, promotion) rely on such measures.
