ReviewTiming of postoperative respiratory emergencies: when do they really occur?
Opioid-induced postoperative respiratory depression has garnered attention and calls for vigilance. However, a higher level of monitoring equates to increased use of hospital resources and is impractical to apply for all postoperative patients. Understanding the temporal pattern of postoperative respiratory emergency occurrences would allow for improved triage of monitoring resources for high-risk patients. Our objective is to describe the temporal pattern of risk of postoperative opioid-induced respiratory failure. ⋯ Emerging evidence indicates that the first postsurgical day carries the highest risk of adverse respiratory events, and this risk is often associated with opioid administration. Resources for increased monitoring should be directed to these high-risk times.

ReviewDoes fluid management affect the occurrence of acute kidney injury?
To describe the potential impact of different fluid management strategies on renal outcomes in critically ill and postoperative patients. ⋯ Although synthetic colloids should be avoided in patients with or at risk of AKI, the renal efficacy of using albumin solutions and/or balanced crystalloids as alternatives to 0.9% sodium chloride in high-risk patients is yet to be confirmed or refuted. Improved goal-directed protocols, which minimize unnecessary fluid administration and reduce potentially harmful effects of fluid overload, need to be developed and tested.

This article reviews the technology and clinical data describing hemodynamic monitoring devices available to anesthesiologists and intensivists caring for patients undergoing thoracic surgical procedures, so that they may better utilize available technology to improve outcomes in this high-risk surgical population. ⋯ Technology that has been shown to improve clinical outcomes in major surgical procedures is likely applicable to patients undergoing thoracic surgical procedures; however, several unique features of these procedures limit or modify the way in which these devices can be used. Understanding the scientific basis of these devices is the key to using them effectively.

As the field of interventional pulmonology continues to expand and develop at a rapid pace, anesthesiologists are increasingly called upon to provide well tolerated anesthetic care during these procedures. These patients may not be candidates for surgical treatment and often have multiple comorbidities. It is important for anesthesiologists to familiarize themselves with these procedures and their associated risks and complications. ⋯ The review summarizes the procedures now commonly performed by interventional pulmonologists and interventional radiologists. It discusses the anesthetic considerations for and common complications of these procedures to prepare anesthesiologists to safely care for these patients. Investigational techniques are also described.
