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
A randomized trial of prewarming on patient satisfaction and thermal comfort in outpatient surgery.
To test the primary hypothesis that forced-air prewarming improves patient satisfaction after outpatient surgery and to evaluate the effect on core temperature and thermal comfort. ⋯ Active prewarming increased thermal comfort but did not significantly reduce redistribution hypothermia or improve postoperative patient satisfaction.

Case Reports
Sevoflurane-associated torsade de pointes in a patient with congenital long QT syndrome genotype 2.
Although patients with congenital long QT syndrome (c-LQTS) are considered to be at high risk for anesthesia, few reports describe c-LQTS genotype-specific considerations for anesthesia. We describe a case of torsade de pointes (TdP) caused by sevoflurane in a patient with c-LQTS genotype 2 (LQT2). A 39-year-old woman diagnosed with c-LQTS was scheduled for an elective therapeutic abortion. ⋯ Postoperative studies revealed a mutation in the KCNH2 gene. Anesthesiologists should note that patients with LQT2 could be more susceptible to volatile anesthetics than are those with other major genotypes. Genotype-specific management of anesthesia may reduce the risk of developing TdP during the perioperative period.

Randomized Controlled Trial
Efficacy of premedication with intranasal dexmedetomidine on inhalational induction and postoperative emergence agitation in pediatric undergoing cataract surgery with sevoflurane.
This study aimed to test the hypothesis that premedication with a single dose of intranasal dexmedetomidine (DEX) could not only reduce preoperative anxiety but also minimize the emergence agitation in children undergoing cataract surgery with sevoflurane anesthesia. ⋯ Intranasal DEX (1 or 2 μg/kg) dose independently improves the incidences of mask acceptance and prevents the incidences of postoperative emergency agitation mainly from sevoflurane without delaying the emergency time or inducing severe adverse events.

Case Reports
Disseminated Staphylococcus aureus infection following spinal anesthesia: a case report.
We here presented a 65-year-old woman with disseminated Staphylococcus aureus infection following spinal anesthesia. The patient underwent spinal anesthesia for great saphenous vein stripping. Twenty days after the procedure, the patient developed hydrocephalus, pulmonary infection, and epidural abscess. ⋯ Appropriate antibiotic therapy and prompt surgical abscess drainage were associated with good outcome. Hydrocephalus is thought to be associated with arachnoiditis caused by S aureus infection, which provides new insights into the pathophysiology of arachnoiditis. Here we reported a case of disseminated S aureus infection following spinal anesthesia, implicating that appropriate interventions should not be delayed for waiting for the microbiological results.
