Factor structure and internal consistency of a Swedish version of the Pain Catastrophizing Scale.
Pain catastrophizing is highly relevant to assess in the context of long-standing pain. The Pain Catastrophizing Scale (PCS) is a well-established questionnaire used to measure catastrophizing in individuals with long-standing pain. So far, no Swedish translation has been evaluated in regard to validity and reliability. The aims of this study were to translate the PCS questionnaire from English to Swedish, and to investigate its construct validity (face, content, and structural validity) and reliability (internal consistency). ⋯ The results indicated adequacy of a three-factor solution and the questionnaire's internal consistency, and provide initial support for the structural validity and internal consistency of a Swedish version of the PCS. Future studies should replicate the study in larger samples and extend the current evaluation in regard to validity and reliability.

Fluid deficits during prolonged overnight fasting in young healthy adults.
Overnight fasting is often prolonged before scheduled surgery, and the extent of perioperative fluid replacement may influence outcome. In clinical practice, basic requirements are estimated at 1.2-2.0 mL·kg-1 ·h-1 , but there is little contemporary clinical data on what deficits result from complete fasting. This prospective preclinical study was designed to determine total fluid loss during overnight fasting, prolonged during daytime. ⋯ Ten hours of overnight fasting in young adults induces fluid deficits at the lower limit of estimated intervals referred to in clinical practice, and hourly weight loss gradually decreases further during prolonged daytime fasting. These findings indicate that current routine procedures do slightly overestimate fluid deficits resulting from prolonged fasting in perioperative clinical practice.

Randomized Controlled TrialAssociation between perioperative hyperoxia and cerebrovascular complications after laparotomy-A post-hoc follow-up study.
Perioperative hyperoxia has been linked to increased long-term mortality. Vasoconstrictive and cellular side effects to hyperoxia have been suggested to increase the risk of coronary and cerebral ischemia. The aim of this post-hoc analysis of a large randomized trial was to compare the effects of 80% vs 30% perioperative oxygen on the long-term risk of stroke or transient cerebral ischemia (TCI) in patients undergoing abdominal surgery. ⋯ Stroke or TCI did not seem related to perioperative inspiratory oxygen fraction. Due to few events, this study cannot exclude that perioperative hyperoxia increases risk of mortality, stroke, or TCI after abdominal surgery.

Optimal PEEP during one-lung ventilation with capnothorax: An experimental study.
One-lung ventilation (OLV) with induced capnothorax carries the risk of severely impaired ventilation and circulation. Optimal PEEP may mitigate the physiological perturbations during these conditions. ⋯ Optimal PEEP was 12-18 cm H2 O and probably relates to capnothorax insufflation pressure. With suboptimal PEEP, ventilation/perfusion mismatch in the ventilated lung and redistribution of blood flow to the nonventilated lung occurred.
