Patient's anxiety and fear of anesthesia: effect of gender, age, education, and previous experience of anesthesia. A survey of 400 patients.
Patients express high anxiety preoperatively, because of fears related to anesthesia and its implications. The purpose of this survey was to gain insight into these fears and to study whether they are affected by patients' sex, age, education, or previous experience of anesthesia. ⋯ All patients, mostly women, express fears about anesthesia; this fear leads to preoperative anxiety. Slight differences are observed for some individual questions among patients of different sex, education level, and previous experience of anesthesia.

Comparative StudyA comparative study between amiodarone and magnesium sulfate as antiarrhythmic agents for prophylaxis against atrial fibrillation following lobectomy.
Atrial fibrillations are common after thoracic surgery. Amiodarone and magnesium sulfate have been used for the management of atrial fibrillation following cardiac and non-cardiac surgery. However, to our knowledge, comparisons of both drugs with each other and with a control group in relation to the prevention of AF following lung surgery have not been performed. Our primary aim in this study was to prospectively evaluate the prophylactic effects of magnesium sulfate and amiodarone used separately and compare them with a control group analyzed retrospectively during and following lobectomy surgeries. ⋯ Our study showed that during the intra- and postoperative periods, both amiodarone and magnesium sulfate are effective at preventing the incidence of atrial fibrillation following lung resection surgery in comparison to the control group.

No renal protection from volatile-anesthetic preconditioning in open heart surgery.
Acute kidney injury (AKI) is a common complication of open heart surgery (OHS). Preconditioning with volatile anesthetics is well proven to provide myocardial protection. Renal protection provided by volatile-anesthetic preconditioning has also been investigated; however, it is still controversial at the clinical level. This study aimed to investigate whether preconditioning with volatile anesthetics could mediate renal protection in OHS. ⋯ This study could not demonstrate volatile-anesthetic-mediated renal protection in OHS. Therefore, in practice, pharmacological preconditioning with volatile anesthetics did not seem to be beneficial.

Randomized Controlled TrialEffects of ramosetron and dexamethasone on postoperative nausea, vomiting, pain, and shivering in female patients undergoing thyroid surgery.
Some antiemetics are effective in the treatment of postoperative pain and shivering, as well as for postoperative nausea and vomiting (PONV). The aim of this study was to investigate the effects of ramosetron and dexamethasone on PONV, pain, and shivering and to determine the correlations between nausea, pain, and shivering. ⋯ Two antiemetic drugs, ramosetron and dexamethasone, significantly reduced the incidence and severity of postoperative nausea and the need for administration of rescue antiemetic drugs. Furthermore, both drugs effectively decreased the severity of pain and shivering. Ramosetron was superior to dexamethasone for reducing nausea, antiemetic consumption, and the severity of nausea, but not for reducing the incidence of shivering. Further studies are required to elucidate the correlations between postoperative nausea, pain, and shivering, as a statistically significant but weak correlation was shown in the present study.
