Goal-directed fluid therapy is an integral component of many Enhanced Recovery After Surgery (ERAS) protocols currently in use. The perioperative clinician is faced with a myriad of devices promising to deliver relevant physiologic data to better guide fluid therapy. The goal of this review is to provide concise information to enable the clinician to make an informed decision when choosing a device to guide goal-directed fluid therapy. ⋯ The ERAS protocols typically involve a multipronged regimen to facilitate early recovery after surgery. Optimizing perioperative fluid therapy is a key component of these efforts. While no technology is without limitations, the majority of the currently available literature suggests esophageal Doppler and arterial waveform analysis to be the most desirable choices to guide fluid administration. Their performance is dependent, in part, on the interpretation of dynamic changes resulting from intrathoracic pressure fluctuations encountered during mechanical ventilation. Evolving practice patterns, such as low tidal volume ventilation as well as the necessity to guide fluid therapy in spontaneously breathing patients, will require further investigation.

Frailty has no single universally accepted definition or method for assessment. It is commonly defined from a physiological perspective as a disruption of homeostatic mechanisms ultimately leading to a vulnerable state. Numerous scoring indices and assessments exist to assist clinicians in determining the frailty status of a patient. The purpose of this review is to discuss the relationship between frailty and perioperative outcomes in surgical patients. ⋯ Patients undergoing surgery who are deemed frail, regardless of the scoring assessment used, have a higher likelihood of experiencing adverse perioperative outcomes. With the lack of a unified definition for frailty, further research is needed to address which assessment method is most predictive of adverse postoperative outcomes.

Prevention of venous thromboembolism in the Enhanced Recovery After Surgery (ERAS) setting: an evidence-based review.
To review the evidence surrounding appropriate prophylaxis for venous thromboembolism (VTE) in patients undergoing surgery. ⋯ Venous thromboembolism is a serious but preventable complication of hospitalization, especially among surgical patients. Historically, it has accounted for a high burden of postoperative morbidity and mortality. In the Enhanced Recovery After Surgery era, our aim should be no less ambitious than the eradication of postoperative VTE.

The optimal management of postoperative pain using multimodal analgesia is a key component of Enhanced Recovery After Surgery (ERAS). Pain has adverse clinical implications on postoperative recovery, including prolonging the time to recovery milestones and length of hospital stay. Moreover, the ubiquity of opioids in postoperative analgesic regimens results in adverse effects, such as sedation, postoperative nausea and vomiting, urinary retention, ileus, and respiratory depression, which can delay discharge. Thus, multimodal analgesia, i.e., the use of more than one analgesic modality to achieve effective pain control while reducing opioid-related side effects, has become the cornerstone of enhanced recovery. The purpose of this review is to address the analgesic techniques used as part of multimodal analgesic regimens to optimize postoperative pain control and to summarize the evidence for their use in reducing opioid requirements and side effects. ⋯ There are continuing advancements in multimodal analgesic techniques; however, postoperative pain in general continues to be undermanaged. Furthermore, a continuing challenge in multimodal pain research related to ERAS is the difficulty in carrying out randomized trials to determine the relative importance of any one component, including analgesia.

Review
What outcomes are important in the assessment of Enhanced Recovery After Surgery (ERAS) pathways?
The purpose of this narrative review is to provide a framework from which to measure the outcomes of Enhanced Recovery After Surgery (ERAS) programs. ⋯ Recovery after surgery is a complex construct. Different outcomes are important at different phases along the recovery trajectory. Measures for quantifying recovery in hospital and after discharge are available. A consensus-based core set of outcomes with input from multiple stakeholders would facilitate research reporting.
