Randomized Controlled Trial Comparative Study
Both lavender fleur oil and unscented oil aromatherapy reduce preoperative anxiety in breast surgery patients: a randomized trial.
The objective of this study was to determine whether lavender fleur oil (LFO) aromatherapy would reduce anxiety when administered to women before undergoing breast surgery. ⋯ Both LFO and UO aromatherapy treatments lowered anxiety before surgery despite no significant changes in vital signs. LFO treatment generated a slight but statistically significant increase in positive feelings compared with UO treatment. It is probable that the beneficial effect observed was due to both aromatherapy with LFO and a placebo effect related to the added attention given to the patients.

Randomized Controlled Trial
Flexible optical intubation via the Ambu Aura-i vs blind intubation via the single-use LMA Fastrach: a prospective randomized clinical trial.
This study was designed to compare the Ambu Aura-i to the single-use LMA Fastrach regarding time to intubation, success rate, and airway morbidity in patients undergoing elective surgery requiring general anesthesia. ⋯ The data suggest that intubation with the ILMA is faster but that first-attempt and overall intubation success rates were comparable in both groups. The results suggest that although the flexible intubating scope-guided Aura-i does not outperform blind intubation via the ILMA, the technique is comparable in terms of first-attempt and overall intubation success rate.

Observational Study
Recovery of laryngeal nerve function with sugammadex after rocuronium-induced profound neuromuscular block.
The aim of this study was to evaluate the efficacy of sugammadex in reversing profound rocuronium-induced neuromuscular block at the laryngeal adductor muscles using motor-evoked potentials (mMEPs). ⋯ Recovery from profound rocuronium-induced block on the larynx is fast and complete with sugammadex. In urgent scenarios, "early" extubation can be performed, even with a TOF ratio ≤0.9. However, all procedures to prevent postoperative residual curarization should still be immediately undertaken.

Case Reports
Reliable low-molecular-weight heparin reversal in a child undergoing emergency surgery: a case report.
Low-molecular-weight heparin neutralization using protamine alone can be unreliable, especially in cases of immediate reversal for emergency surgery. Here, we describe a unique case of a 17-month-old girl with a history of glioneuronal tumor and corresponding hydrocephalus status post debulking and ventriculoperitoneal shunt placement, who was placed on enoxaparin after the development of a sagittal sinus thrombosis. Patient presented for emergency craniectomy and evacuation of subdural bleed after a fall while on therapeutic dose of enoxaparin. Protamine and fresh frozen plasma were used in the patient's perioperative course providing a reliable reversal of enoxaparin.

Although anxiolytic-sedative agents are used preoperatively since the advent of anesthesia, many aspects of this treatment, including the intended effects among which anxiolysis, effectiveness, and optimal agents, remain unclear. The objective of this study was to provide insight into the preoperative use of anxiolytic-sedative agents in the Netherlands and to relate the administration of these agents to the anxiolytic-sedative state of patients. ⋯ Anxiolytic-sedative agents are used preoperatively in a substantial number of patients in the Netherlands, and the pharmacokinetic characteristics of many agents are not optimal of their intended use. In addition, we found no relationship with reduced anxiety. This study stresses the need for clear guidelines on preoperative use of anxiolytic-sedative agents.
