The accurate assessment of intravascular volume status for the therapy of severe hypovolemia and shock is difficult and critical to critically ill patients. Non-invasive evaluation of fluid responsiveness by the rapid infusion of a very limited amount of volume is an important clinical goal. This study aimed to test whether echocardiographic parameters could predict fluid responsiveness in critically ill patients following a low-volume (50-ml crystalloid solution) infusion over 10 seconds. ⋯ In critically ill patients, the variation of CO and VTI after the administration of 50-ml crystalloid solution over 10 seconds (∆CO50 and ∆VTI50) can accurately predict fluid responsiveness.

Multicenter Study Comparative StudyPathway From Central Obesity to Childhood Asthma: Physical Fitness and Sedentary Time Are Leading Factors.
Available prospective studies of obesity and asthma have used only body mass index (BMI) as an indicator for adiposity; studies using detailed obesity measures are lacking, and the role of physical fitness level and sedentary time remains unexplored in the link between obesity and asthma. ⋯ Central obesity measures should be incorporated in childhood asthma risk predictions. Children are encouraged to increase their physical fitness levels and reduce their sedentary time to prevent central obesity-related asthma.

Observational StudyEffect of osmotherapy on optic nerve sheath diameter in patients with increased intracranial pressure.
The measurement of ocular nerve sheath diameter (ONSD) via ocular ultrasound scanning is a recent non-invasive method for intracranial pressure (ICP) assessment. Few clinical studies have assessed ONSD variations during osmotherapy for the treatment of sustained increased ICP episodes. The aim of our study was to determine the rate of ONSD variation after mannitol administration for increased ICP episodes. ⋯ The ONSD significantly decreased after mannitol infusion from 6.3 (6.1-6.7) to 5. mm (5.5-6.3) (p=0.0007). Concomitantly, the intracranial pressure decreased from 35 (32-41) to 25 (22-29) mmHg (p=0.001) and the CPP increased from 47 (50-60) to 66 (59-69) mmHg (p=0.003). The variations of ONSD appear to be an interesting parameter to evaluate the efficacy of osmotherapy for elevated ICP episodes in patients with acute brain injury.

Randomized Controlled Trial Multicenter StudyA pilot study for a prospective, randomized, double-blind trial of the influence of anesthetic depth on long-term outcome.
Greater depth of anaesthesia may be associated with a higher incidence of wound infection, mortality and composite risk of complications.

Comparative StudyA Prospective Comparison of a Noninvasive Cardiac Output Monitor Versus Esophageal Doppler Monitor for Goal-Directed Fluid Therapy in Colorectal Surgery Patients.
The NICOM non-invasive cardiac output monitor is non-inferior to oesophageal doppler monitoring for guiding fluid therapy in colorectal surgery.
