Case ReportsProbable case of vascular air embolism during endonasal CO2 laser surgery.
Laser surgery in narrow luminal cavities can lead to venous air embolism (VAE) due to high pressure or high flow clearing/cooling systems. We report the first case of initially misdiagnosed VAE during endonasal CO(2) laser surgery. A 56-year-old patient underwent uvulopalatopharyngoplasty and septoplasty with bilateral CO(2) laser turbinoplasty for turbinate hypertrophy and uvula deviation. ⋯ The literature reports cases of VAE during laser surgery in narrow luminal cavities. When operating in narrow luminal cavities, using a liquid instead of a gas as a clearing/cooling system for the distal end of the probe in laser instruments and avoiding direct contact with tissues is advisable. Anesthesiologists, surgeons and the nursing staff practicing endoscopic laser surgery should have wide knowledge of the risks linked to this technique in order to minimize risk to the patient and to manage VAE should it eventually occur.

Focused echocardiography entry level: new concept of a 1-day training course.
We describe a training programme for non-specialists in focused echocardiography in the periresuscitation setting which represents an entry level in echocardiography training (FEEL) for emergency and critical care medicine physicians. ⋯ Periresuscitation echocardiography, performed safely, within the competence of practitioners in an ALS-compliant manner is a potentially valuable skill to be acquired by physicians caring for the critically ill, regardless of the environment in which they work, or their level of seniority. This newly-developed blended learning periresuscitation echocardiography programme (FEEL) may serve as entry level in peri-resuscitation echocardiography for both emergency physicians and critical care practitioners.

Review Comparative StudyDopamine versus norepinephrine: is one better?
Dopamine and norepinephrine are widely used as first line agents to correct hypotension in patients with acute circulatory failure. There has been considerable debate in recent years as to whether one is better than the other. ⋯ However, dopamine has potentially detrimental effects on the release of pituitary hormones and especially prolactin, although the clinical relevance of these effects is unclear. Observational studies have provided conflicting results regarding the effects of these two drugs on outcomes, and results from a recently completed randomized controlled trial are eagerly waited.

ReviewTargeting transpulmonary pressure to prevent ventilator induced lung injury.
Acute respiratory distress syndrome (ARDS) and ventilator induced lung injury (VILI) continue to challenge clinicians who care for the critically ill. Current research in ARDS has focused on ventilator strategies to improve the outcome for these patients. In this review, we emphasize the limitations of managing ventilators based on airway pressures alone. ⋯ This review suggests that perturbations in chest wall compliance and transpulmonary pressure may explain the lack of efficacy observed in recent clinical trials of ventilator management. We present a method for estimating pleural and transpulmonary pressures from esophageal manometry. Quantifying these variables and individualizing ventilator management based on individual patient physiology may be useful to intensive care clinicians who treat patients with ARDS.

Randomized Controlled TrialBispectral index-guided intraoperative sedation with dexmedetomidine and midazolam infusion in outpatient cataract surgery.
This study aimed to evaluate the role of alfa-2 agonist infusion, with dexmedetomidine or midazolam, on hemodynamic and respiratory parameters while titrating the sedation level with the bispectral index (BIS) during cataract surgery. ⋯ Dexmedetomidine infusion mildly decreased heart rate in the later periods of surgery with better pain scores in the postoperative period. Dexmedetomidine should be an alternative for intraoperative sedation in outpatient cataract surgery.
