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.

Cardiovascular complications signify a major cause of morbidity and mortality in patients undergoing vascular surgery adversely affecting both short- and long-term prognosis. During the last decade, unmet needs for a distinct cardiovascular risk assessment have led to an intensive research for establishment of biomarkers with sufficient predictive value. This literature review aims in examining the value of several biomarkers in predicting the incidence of major adverse cardiac events in vascular surgery patients. ⋯ These biomarkers can be used in clinical practice as outcome predictors, although sensitivity and specificity varies. Detection of subclinical cardiovascular damage may improve total risk estimation and facilitate clinical assessment of patients at risk for future cardiovascular events. The wide variety of sensitivity and specificity in predicting a MACE of these biomarkers exert the need for future trials in which these markers will be tested as adjunctive tools of cardiovascular risk estimation scoring systems.

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.
