Observational StudyTissue near infra red spectroscopy change is not correlated with patients' outcome in elective cardiac surgery.
Microcirculatory disturbances following cardiac surgery with cardiopulmonary bypass (CPB) are thought to be at the origin of organ dysfunction, although few studies have correlated microvascular alterations with outcome. We aimed to assess the microcirculation with near infrared spectroscopy (NIRS) and correlate NIRS parameters with intensive care length of stay and organ dysfunction. ⋯ This study confirms, through a non-invasive technology, a significant but transient alteration of the microcirculation during elective cardiac surgery. However, as these microvascular alterations were not correlated with patient's outcome, NIRS-derived parameters seem to be of limited interest in the cardiac surgery setting.

Although the incidence of acute pancreatitis among children is less than that in adults, the physical and psychosocial impact on children and their families can be overwhelming. Pancreatitis is manifested as pain accompanied by a host of other complex issues. ⋯ Management after discharge from the hospital is often an ongoing stress for these patients and families, and multiple admissions to the intensive care unit may be necessary for feeding and pain complications. Presented in the context of an actual clinical case at a 500-bed tertiary care pediatric hospital, this patient's scenario illustrates the importance of ensuring adequate nutrition, maintaining hydration, providing appropriate pain management, and preventing infection and thromboembolic events.

Comparative Study Clinical TrialThe median effective dose of dexmedetomidine for laryngeal mask airway insertion with propofol 2.0 mg/kg.
Dexmedetomidine can be used as a co-induction agent to facilitate laryngeal mask airway (LMA) insertion with minimal effect on respiratory function. The purpose of the study was to determine the median effective dose (ED50) of dexmedetomidine to facilitate LMA insertion during anaesthesia induction with propofol 2.0 mg/kg without neuromuscular blockade. ⋯ The single dose of dexmedetomidine for successful LMA insertion to be feasible in 50% of patients was 0.55 μg/kg during anaesthesia induction with propofol 2 mg/kg.

The difficulty in identifying the onset of low back pain (LBP) limits the capacity to determine the incidence of LBP at the population level and, further, to identify risk factors. In the literature, incidence cohorts have been built with patients initially considered LBP-free for 6-12 months prior to their selection. This 'clearance period' might not be sufficient to exclude recurrent patients having experienced previous LBP episodes and might result in a misclassification bias. ⋯ Screening the medical history of LBP patients can provide more accurate incidence estimates by limiting the over-ascertainment of first-time LBP patients. A 4- to 7-year clearance period should be considered.
