Randomized Controlled Trial Comparative Study Clinical Trial
Ambulatory electrical external cardioversion with propofol or etomidate.
To compare, in pairwise fashion, the effects of propofol and etomidate during ambulatory cardioversion and early recovery. ⋯ Etomidate and propofol are both useful during ambulatory external electrical cardioversion. The described doses maintain stable hemodynamic conditions in nonpremedicated patients. Recovery scores and psychomotor test indicate a faster recovery in the propofol group. However, no intergroup differences were noted at 20 minutes after the cardioversion. A safe discharge of all patients from the critical care unit or postanesthesia care unit to the ward can be considered after 30 minutes.

Randomized Controlled Trial Clinical Trial
Preoperative combined with intraoperative skin-surface warming avoids hypothermia caused by general anesthesia and surgery.
To evaluate the effects of intraoperative skin-surface warming with and without 1 hour of preoperative warming, in preventing intraoperative hypothermia, and postoperative hypothermia, and shivering, and in offering good conditions to early tracheal extubation. ⋯ One hour of preoperative warning combined with intraoperative skin-surface warming, not simply intraoperative warming alone, avoided hypothermia caused by general anesthesia during the first two hours of surgery. Both methods prevented postoperative hypothermia and shivering and offered good conditions for early tracheal extubation.

Norepinephrine (NE) is mostly used to treat severe hypotension. However, NE has potentially adverse vasoconstrictive effects on regional vascular beds of kidney, liver, and gut, with a potential for ensuing organ dysfunction. NE therefore is considered as a last reserve in otherwise refractory hypotension. ⋯ Therefore, the doses of NE needed to maintain or restore blood pressure may be extremely high. Surprisingly, no adverse vasoconstriction with subsequent hypoperfusion occurs during sepsis, despite the high doses of NE administered. Instead, NE rather causes an increase in blood flow and oxygen delivery.

Difficult airway management is a critical aspect of anesthesiology training and practice. A survey was conducted of American anesthesia residency programs to determine the prevalence of a specific airway rotation and its curriculum. ⋯ Of the programs with an airway rotation, the flexible fiberoptic bronchoscope and the laryngeal mask airway represent the most frequently used devices, excluding the standard laryngoscopes. There is minimum emphasis on more invasive techniques. Traditional methods of instruction continue to be utilized more frequently than nontraditional methods.

Wound infiltration with ropivacaine and fentanyl: effects on postoperative pain and PONV after breast surgery.
To determine whether postoperative wound infiltration with local anesthetics combined with fentanyl improves analgesia following breast surgery; and to investigate awakening and postoperative nausea/vomiting. ⋯ Postsurgical ropivacaine wound infiltration, with or without adding fentanyl, demonstrates no differences in postoperative pain relief and nausea/vomiting compared to a balanced general anesthetic including i.v. fentanyl.
