Factors associated with preoperative anxiety levels of Turkish surgical patients: from a single center in Ankara.

BACKGROUND: Preoperative anxiety and stress are undoubtedly a difficult experience in patients undergoing elective surgery. These unpleasant sensations depend on several factors. The objective of this study was to evaluate the preoperative anxiety levels in a sample of Turkish population, as well as the underlying causes using the Spielberger State-Trait Anxiety Inventory (STAI anxiety) scale. METHODS: The study was conducted according to the Declaration of Helsinki and was approved by the local ethical committee. All participants gave written informed consent upon having received detailed information on the study. Upon entry in the study, state and trait anxiety questionnaires were completed by 186 patients scheduled for elective surgery. The influencing factors in regard to age, sex, educational status and others were also reported. RESULTS: There was a statistically significant positive correlation between state and trait anxiety scores in this Turkish population. While the most important predictive factors that affected state-STAI scores were age, sex and duration of sleep the night before surgery; educational status and age were the best predictors for determining the variation in trait-STAI scores. CONCLUSION: The factors affecting anxiety levels in different populations might vary among different countries. Interestingly, in this sample of Turkish population, the trait anxiety levels were found to be higher from state-anxiety levels, especially in women and less educated people. Thus, doubts about operation and anesthesia are overlooked. This could be attributed to the low to intermediate life standards of people admitted to our hospital.

Anesthetic management and perioperative complications in transcatheter aortic valve implantation: the Turkish experience.

BACKGROUND/AIM: To describe the anesthetic management and early results of transcatheter aortic valve implantation (TAVI) in a single center in Turkey. MATERIALS AND METHODS: We evaluated 79 (54 females, 25 males; mean age: 76 ± 9 years) consecutive symptomatic patients with severe aortic stenosis who underwent TAVI under general anesthesia between July 2011 and September 2012. We preferred a transfemoral approach as the first option. RESULTS: The duration of anesthesia was 149 ± 49 min. Thirty-eight percent of the patients were extubated in the cardiac catheterization laboratory. Three patients required a permanent pacemaker, while 8 patients required inotropic support in the postoperative period. Mortality rate was 9% within 30 days. Fifteen patients had vascular complications, of which 53% were treated surgically. CONCLUSION: Today, as a result of developments in technology, TAVI can be considered as a beneficial alternative treatment option for inoperable aortic stenosis patients. Thus, anesthesiologists will be confronted with a number of TAVI cases, and so they should be prepared to face issues related to the patient's safety both during the administration of anesthesia and in the postoperative period in the near future.

Serotonin syndrome caused by administration of methylene blue to a patient receiving selective serotonin reuptake inhibitors.

A 31-year-old man who had surgery after a gunshot injury was recovering in the intensive care unit when a sudden deterioration in his condition occurred after enteral administration of methylene blue to detect a fistula. Serotonin syndrome was diagnosed based on hyperthermia, ocular clonus, and excessive diaphoresis.
