Skin temperature as a noninvasive marker of haemodynamic and perfusion status in adult cardiac surgical patients: an observational study.
Foot temperature has long been advocated as a reliable noninvasive measure of cardiac output despite equivocal evidence. The aim of this pilot study was to investigate the relationship between noninvasively measured skin temperature and the more invasive core-peripheral temperature gradients (CPTGs), against cardiac output, systemic vascular resistance, serum lactate, and base deficit. ⋯ These results support the utilisation of skin temperature as a noninvasive marker of cardiac output and perfusion. The use of CPTG was shown to be unnecessary, given the parallels in results with the less invasive skin temperature parameters. A larger study is however required to validate these findings.

ReviewEndotracheal suctioning of the adult intubated patient--what is the evidence?
Intubated patients may be unable to adequately cough up secretions. Endotracheal suctioning is therefore important in order to reduce the risk of consolidation and atelectasis that may lead to inadequate ventilation. The suction procedure is associated with complications and risks including bleeding, infection, atelectasis, hypoxemia, cardiovascular instability, elevated intracranial pressure, and may also cause lesions in the tracheal mucosa. The aim of this article was to review the available literature regarding endotracheal suctioning of adult intubated intensive care patients and to provide evidence-based recommendations The major recommendations are suctioning only when necessary, using a suction catheter occluding less than half the lumen of the endotracheal tube, using the lowest possible suction pressure, inserting the catheter no further than carina, suctioning no longer than 15s, performing continuous rather than intermittent suctioning, avoiding saline lavage, providing hyperoxygenation before and after the suction procedure, providing hyperinflation combined with hyperoxygenation on a non-routine basis, always using aseptic technique, and using either closed or open suction systems.

ReviewLocal experience with the use of sustained low efficiency dialysis for acute renal failure.
Renal replacement therapy (RRT) is a common therapy used to treat critically ill patients in acute renal failure. Currently a number of dialysis modalities are used such as haemodialysis, continuous renal replacement therapy (CRRT), and sustained low efficiency dialysis (SLED). As SLED is a recently implemented RRT, very little literature is available on the nursing aspects of SLED. ⋯ Nursing advantages of SLED over CRRT included being able to release the patient for nursing activities and patient transfer out of the ICU for investigations and procedures; reduced nursing workload related to less machine and patient monitoring during the dialysis procedure; and cost reduction. Disadvantages of SLED are related to poor water quality, accessibility of water supply and limited space to house the two machines required. SLED has proven to be a nurse friendly dialysis modality for critically ill patients with acute renal failure.

The experiences of families of critically ill patients in Greece: a social constructionist grounded theory study.
The experiences of patients' families in intensive care units (ICUs) are of international concern. In Greece however, adequate attention has not been paid to this issue. ⋯ The study has examined the experience of Greek patients' families from a qualitative perspective and suggests that major changes need to be made in terms of management and support.

Lung recruitment--a nurse and/or physician task. A national survey on requirements for education, regulations and guidelines.
International and national guidelines on requirements for performing lung recruitment manoeuvres are lacking. This paper presents a nationwide descriptive survey of the occurrence of and conditions for lung recruitment in adult patients treated with mechanical ventilation in intensive care units (ICUs) in Sweden. All ICUs except neurological, cardiac, paediatric and neonatal ICUs were invited (N=73); of these, 60 ICUs participated in the study (82%). ⋯ Lung recruitment was performed more often in units where both physicians and nurses performed lung recruitment than in units where only physicians performed the manoeuvres (46% vs. 12%, p=0.03). Further, local guidelines on lung recruitment manoeuvres were more common in units where both physicians and nurses performed this treatment (71% vs. 41%, p=0.02). The results suggest that recommendations of repeated and prompt lung recruitment manoeuvres are better met if nurses, along with physicians, perform lung recruitment.
