Observational StudyMinimal impairment in pulmonary function following laparoscopic surgery.
Pulmonary function may be impaired in connection with laparoscopic surgery, especially in the head-down body position, but the clinical importance has not been assessed in detail. The aim of this study was to assess pulmonary function after laparoscopic hysterectomy and laparoscopic cholecystectomy. We hypothesised that arterial oxygenation would be more impaired after hysterectomy performed in the head-down position than after cholecystectomy in the head-up position. ⋯ Minimal impairment in pulmonary gas exchange was found after laparoscopic surgery. Pulmonary shunt was larger after laparoscopic cholecystectomy, but no clinically significant differences in postoperative pulmonary gas exchange or spirometry were found between laparoscopic hysterectomy and laparoscopic cholecystectomy.

Case Reports[Case report - Intraosseous infusion as an alternative solution in the therapy of septicaemia in an adult].
The intraosseous access can be more often found in the guidelines and recommendations of the medical societies when an peripheral or central venous catheter cannot be established. For the adult this can mostly be found for the cardiopulmonary resuscitation or the patient with major trauma. In pediatrics and neonatology it is a reliable solution for the child in septic shock. ⋯ After stabilizing circulatory function and volume replacement a central-venous catheter could be placed and the patient was successfully surgically sanified. We used the EZ-IO((Vidacare Corporation, San Antonio/USA). Appropriate systems should extensively be available in the clinical setting.

The work hours of Norwegian physicians are under scrutiny because of an increased public focus on patient safety. Ample international research indicate harmful effects of doctor fatigue based on studies on physicians working long weeks and on-call shifts of more than 30 consecutive hours. There is a lack of research on effects relevant for short or intermediate length of work weeks and call shifts. This study intended to study cognitive effects of short or intermediate duration in-hospital calls. ⋯ Reaction times were increased after 18 h night calls and non-significant increases in reaction times were apparent after the other on-call shifts. Self reported sleepiness was increased post-call. We were not able to conclude whether executive function or memory was negatively affected post-call.

ReviewCritical care strategies to improve neurocognitive outcome in thoracic surgery.
This review focuses on neurocognitive outcome with respect to potential pathophysiological inflammatory mechanisms of thoracic surgery and one-lung ventilation, risk factors of postoperative delirium and postoperative cognitive dysfunction (POCD) as well as anti-inflammatory strategies. ⋯ There is evidence that important key strategies improve neurocognitive outcome after thoracic surgery. This includes adequate risk stratification, the anesthetic management and postoperative critical care strategies.

The relative importance of respiratory viral infections vs inhalant allergy in asthma pathogenesis is the subject of ongoing debate. Emerging data from long-term prospective birth cohorts are bringing increasing clarity to this issue, in particular through the demonstration that while both of these factors can contribute independently to asthma initiation and progression, their effects are strongest when they act in synergy to drive cycles of episodic airways inflammation. An important question is whether susceptibility to infection and allergic sensitization in children with asthma arises from common or shared defect(s). ⋯ The effects of these defects in DCs from children wtih asthma are accentuated by parallel attenuation of innate immune functions in adjacent airway epithelial cells that reduce their resistance to the upper respiratory viral infections, which are the harbingers of subsequent inflammatory events at asthma lesion site(s) in the lower airways. An important common factor underpinning the innate immune functions of these unrelated cell types is use of an overlapping series of pattern recognition receptors (exemplified by the Toll-like receptor family), and variations in the highly polymorphic genes encoding these receptors and related molecules in downstream signaling pathways appear likely contributors to these shared defects. Findings implicating recurrent respiratory infections in adult-onset asthma, much of which is nonatopic, suggest a similar role for deficient immune surveillance in this phenotype of the disease.
