Randomized Controlled Trial Comparative StudyEndotracheal tube size and sore throat following surgery: a randomized-controlled study.
Women experience less frequent and less severe sore throat postoperatively after intubation with a size 6.0 ETT versus size 7.0.

Dopamine increases renal oxygenation: a clinical study in post-cardiac surgery patients.
Imbalance of the renal medullary oxygen supply/demand relationship can cause ischaemic acute renal failure (ARF). The use of dopamine for prevention/treatment of ischaemic ARF has been questioned. It has been suggested that dopamine may increase renal oxygen consumption (RVO(2)) due to increased solute delivery to tubular cells, which may jeopardize renal oxygenation. Information on the effects of dopamine on renal perfusion, filtration and oxygenation in man is, however, lacking. We evaluated the effects of dopamine on renal blood flow (RBF), glomerular filtration rate (GFR), RVO(2) and renal O(2) demand/supply relationship, i.e. renal oxygen extraction (RO(2)Ex). ⋯ In post-cardiac surgery patients, dopamine increases the renal oxygenation by a pronounced renal pre-and post-glomerular vasodilation with no increases in GFR, tubular sodium reabsorption or renal oxygen consumption.

Randomized Controlled Trial Comparative StudySparing the larynx during gynecological laparoscopy: a randomized trial comparing the LMA Supreme and the ETT.
We designed a prospective randomized single-blind study to compare efficiency and post-operative upper airway morbidity when the laryngeal mask airway (LMA) Supreme is used as an alternative to the endotracheal tube (ETT). ⋯ We demonstrated that choosing an LMA Supreme was an efficient pharyngolaryngeal morbidity-sparing strategy. Moreover, we showed that the LMA Supreme and the ETT were equally effective airways for a routine gynecological laparoscopy procedure.

Randomized Controlled Trial Comparative StudySingle stimulation of the posterior cord is superior to dual nerve stimulation in a coracoid block.
Both multiple injection and single posterior cord injection techniques are associated with extensive anesthesia of the upper limb after an infraclavicular coracoid block (ICB). The main objective of this study was to directly compare the efficacy of both techniques in terms of the rates of completely anesthetizing cutaneous nerves below the elbow. ⋯ Injection of a local anesthetic after a single stimulation of the radial nerve fibers produced more extensive anesthesia than using a dual stimulation technique under the conditions of our study.

Implementing a pre-operative checklist to increase patient safety: a 1-year follow-up of personnel attitudes.
The operating room is a complex work environment with a high potential for adverse events. Protocols for perioperative verification processes have increasingly been recommended by professional organizations during the last few years. We assessed personnel attitudes to a pre-operative checklist ('time out') immediately before start of the operative procedure. ⋯ Staff attitudes toward a surgical checklist were mostly positive 1 year after their introduction in two large hospitals in central Sweden.
