Is Activity Tracker-Measured Ambulation an Accurate and Reliable Determinant of Postoperative Quality of Recovery? A Prospective Cohort Validation Study.
Quality of recovery (QOR) instruments measure patients' ability to return to baseline health status after surgery. Whether, and the extent to which, postoperative ambulation contributes to QOR is unclear, in part due to the lack of valid tools to measure ambulation in clinical settings. This cohort study of the cesarean delivery surgical model examines the accuracy and reliability of activity trackers in quantifying early postoperative ambulation and investigates the correlation between ambulation and QOR. ⋯ This study demonstrated the accuracy and reliability of activity trackers in measuring ambulation in clinical settings and suggested that postoperative ambulation is a determinant of postoperative QOR. A hypothetical implication of our findings is that interventions that improve ambulation may also help to enhance QOR, but further research is needed to establish a causal relationship.

National Partnership for Maternal Safety Recommended Maternal Early Warning Criteria Are Associated With Maternal Morbidity.
Many cases of maternal mortality and morbidity are preventable. A delayed response to clinical warning signs contributes to preventability. Therefore, the National Partnership for Maternal Safety devised maternal early warning criteria (MEWC), composed of abnormal vital signs that trigger bedside evaluation by a provider with the capacity to escalate care. The relationship of the MEWC to maternal morbidity has not been studied. We evaluated the correlation between the MEWC and maternal morbidity. ⋯ The MEWC are associated with maternal morbidity. As a screening tool, they appropriately prioritize sensitivity and have an excellent negative predictive value. The criteria demonstrate low specificity, which is slightly improved by considering only patients with recurrent or multiple triggers. Additional efforts to improve the specificity of MEWC, with a focus on identifying sustained or recurrent patterns of abnormal vital signs, may be necessary before their widespread implementation.

Distraction-Free Induction Zone: A Quality Improvement Initiative at a Large Academic Children's Hospital to Improve the Quality and Safety of Anesthetic Care for Our Patients.
Noise in the operating room may cause distractions during critical periods and impair reliable communication between staff. Even momentary inefficiency while administering anesthesia can lead to errors and serious consequences for the patient. Distractions to an anesthesia provider during critical periods such as induction and emergence are a patient safety issue. Because of concerns regarding unacceptable noise levels and distractions during induction of general anesthesia, our institution developed a quality improvement initiative, the "Distraction-Free Induction Zone." The specific aim of this project was to decrease the percentage of cases with a distraction, described as music, unnecessary conversations, or loud noises, occurring during induction of general anesthesia in pediatric otolaryngology operating rooms from 61% to 15%. ⋯ Using improvement science methods, we observed a decrease in distractions during induction of general anesthesia, improved a process, and encouraged change in culture at a large academic children's hospital to enhance the quality and safety of the anesthetic care we provide our patients.

Objective Epidural Space Identification Using Continuous Real-Time Pressure Sensing Technology: A Randomized Controlled Comparison With Fluoroscopy and Traditional Loss of Resistance.
Performance of epidural anesthesia and analgesia depends on successful identification of the epidural space (ES). While multiple investigations have described objective and alternative methodologies to identify the ES, traditional loss of resistance (LOR) and fluoroscopy (FC) are currently standard of care in labor and delivery (L&D) and chronic pain (CP) management, respectively. While FC is associated with high success, it exposes patients to radiation and requires appropriate radiological equipment. LOR is simple but subjective and consequently associated with higher failure rates. The purpose of this investigation was to compare continuous, quantitative, real-time, needle-tip pressure sensing using a novel computer-controlled ES identification technology to FC and LOR for lumbar ES identification. ⋯ Objective lumbar ES identification using continuous, quantitative, real-time, needle-tip pressure measurement with the CompuFlo Epidural Computer Controlled Anesthesia System resulted in noninferior success rates when compared to FC and LOR for CP management and L&D, respectively. Benefits of this novel technology may include nonexposure of patients to radiation and contrast medium and consequently reduced health care costs.

Dexmedetomidine-Mediated Prevention of Renal Ischemia-Reperfusion Injury Depends in Part on Cholinergic Anti-Inflammatory Mechanisms.
Organ ischemia-reperfusion injury often induces local and systemic inflammatory responses, which in turn worsen organ injury. These inflammatory responses can be regulated by the central nervous system, particularly by the vagal nerve and nicotinic acetylcholine receptors, which are the key components of cholinergic anti-inflammatory pathway. Activation of the cholinergic anti-inflammatory pathway can suppress excessive inflammatory responses and be a potential strategy for prevention of ischemia-reperfusion injury of organs including the kidney. ⋯ Our findings suggest that Dex provides renoprotection, at least in part, through anti-inflammatory effects of the parasympathetic nervous system activation in addition to its direct actions on α2-adrenergic receptors.
