Review Meta Analysis
Impact of Right Ventricular Dysfunction on Short- and Long-Term Mortality in Sepsis: A Meta-Analysis of 1,373 Patients.
Right ventricular (RV) dysfunction in sepsis and septic shock has been infrequently studied and has uncertain prognostic significance. ⋯ In this meta-analysis of observational studies, RV dysfunction was associated with higher short-term and long-term mortality in sepsis and septic shock.

Although clinical studies have evaluated dexmedetomidine as a strategy to improve noninvasive ventilation (NIV) comfort and tolerance in patients with acute respiratory failure (ARF), their results have not been summarized. ⋯ Compared with any sedation strategy or placebo, dexmedetomidine reduced the risk of delirium and the need for mechanical ventilation while increasing the risk of bradycardia and hypotension. The results are limited by imprecision, and further large RCTs are needed.

Historically, β-blockers have been considered to be relatively contraindicated for septic shock because they may cause cardiac suppression. On the other hand, there is an increasing interest in the use of β-blockers for treating patients with sepsis with persistent tachycardia despite initial resuscitation. ⋯ The use of ultrashort-acting β-blockers such as esmolol and landiolol in patients with sepsis with persistent tachycardia despite initial resuscitation was associated with significantly lower 28-day mortality.

The purpose of this review was to describe our management approach to patients with treatment-emergent central sleep apnea (TECSA). The emergence of central sleep apnea during positive airway pressure therapy occurs in approximately 8% of titration studies for OSA, and it has been associated with several demographic, clinical, and polysomnographic factors, as well as factors related to the titration study itself. TECSA shares similar pathophysiology with central sleep apnea. ⋯ CPAP therapy remains a standard therapy for TECSA. Expectant management is appropriate given its transient nature in most cases, whereas select patients would benefit from an early switch to an alternative positive airway pressure modality. Other treatment options include supplemental oxygen and pharmacologic therapy.
