The Effect of Night Float Rotation on Resident Sleep, Activity, and Well-Being.

BACKGROUND: Night float call systems are becoming increasingly common at training programs with the goal of reducing fatigue related to sleep deprivation and sleep disturbance. Previous studies have shown that trainees obtain less sleep during the night float rotation and have decreased sleep efficiency for several days after the rotation. The impact on physical and emotional well-being has not been documented. METHODS: Twenty-seven anesthesia residents were enrolled in a study using wearable sleep and activity trackers and National Institutes of Health Patient-Reported Outcome Measurement Information System (NIH PROMIS) surveys for sleep disturbance, fatigue, and positive affect to record data the week before ("baseline"), during ("night float"), and 1 week after ("recovery") their night float rotation. Each subject's data during the night float week and recovery week were compared to his or her own baseline week data using a paired, nonparametric analysis. The primary outcome variable was the change in average daily sleep hours during the night float week compared to the baseline week. Average daily rapid eye movement (REM) sleep, daily steps, and NIH PROMIS scores comparing night float and recovery weeks to baseline week were prespecified secondary outcomes. NIH PROMIS scores range from 0 to 100 with 50 as the national mean and more of the construct having a higher score. RESULTS: There was no difference in average daily sleep hours between the night float and the baseline weeks (6.7 [5.9-7.8] vs 6.7 [5.5-7.7] hours, median [interquartile range]; P = .20). Residents had less REM sleep during the night float compared to the baseline weeks (1.1 [0.7-1.5] vs 1.4 [1.1-1.9] hours, P = .002). NIH PROMIS fatigue scores were higher during the night float than the baseline week (58.8 [54.6-65.1] vs 48.6 [46.0-55.1], P = .0004) and did not return to baseline during the recovery week (51.0 [48.6-58.8], P = .029 compared to baseline). Sleep disturbance was not different among the weeks. Positive affect was reduced after night float compared to baseline (39.6 [35.0-43.5] vs 44.8 [40.1-49.6], P = .0009), but returned to baseline during the recovery week (43.6 [39.6-48.2], P = .38). CONCLUSIONS: The residents slept the same number of total hours during their night float week but had less REM sleep, were more fatigued, and had less positive affect. All of these resolved to baseline except fatigue, that was still greater than the baseline week. This methodology appears to robustly capture psychophysiological data that might be useful for quality initiatives.

Perioperative Efficiency of Sugammadex Following Laparoscopic Cholecystectomy in Clinical Practice.

Background: Studies have proposed that the routine use of the modified gamma-cyclodextrin, sugammadex, could provide perioperative time savings. However, these investigations have been limited to small group analyses. The purpose of this study was to test the effectiveness of sugammadex on perioperative times when compared to neostigmine under general clinical practice conditions following rocuronium-induced neuromuscular blockade for laparoscopic cholecystectomy. Methods: Following institutional review board approval, data from 1,611 consecutive surgical records for laparoscopic cholecystectomy were reviewed. Patient characteristics, type of primary neuromuscular blocking reversal agent, operating room (OR) discharge times, and postanesthesia care unit (PACU) recovery times were the measures of interest. Equivalence testing was used to determine the between-group differences of the reversal agents in the two perioperative time periods of interest. Results: OR discharge times averaged 10.9 (95% CI, 10-11.8) minutes for patients administered sugammadex and 8.9 (95% CI, 8.2-9.7) minutes for patients administered neostigmine. PACU recovery times averaged 77.6 (95% CI, 74.1-81.1) minutes for sugammadex and 68.6 (95% CI, 65.9-71.3) minutes for neostigmine. Equivalence testing demonstrated no improvement in the two perioperative times with sugammadex. Conclusion: These results suggest no perioperative time savings with sugammadex when compared to neostigmine following laparoscopic cholecystectomy under general clinical practice conditions.

Macrolide and fluoroquinolone mediated cardiac arrhythmias: clinical considerations and comprehensive review.

While there is evidence for cardiac arrhythmias associated with macrolide and fluoroquinolone antibiotics, there is still debate among health care providers as to whether this risk of arrhythmia is overstated. A joint panel of the US Food and Drug Administration suggested that macrolide and fluoroquinolone labels need much stronger warnings regarding the possible serious adverse cardiac effects associated with these antibiotics, especially since they are so widely prescribed. And while health care providers may differ on the pertinence of the cardiac risks associated with antibiotic use, they can undoubtedly minimize the cardiac effects that are associated with these antibiotics by paying attention to the cardiac risk factors and drug history associated with the patient. Relevant studies for our review were identified from a PubMed search using keywords and combined word searches involving macrolides, fluoroquinolones, and cardiac arrhythmias. We attempted to include as many recent (>2015) articles as possible. We included case reports, randomized, controlled trials, observational studies, case-control studies, systematic reviews, and retrospective studies. Underlying cardiac issues can predispose patients to harmful cardiac side effects that can be exacerbated in the presence of antibiotics. The health care provider should rule out any risk factor associated with antibiotic-induced cardiac arrhythmia in the event that a patient does need a macrolide or fluoroquinolone antibiotic. Rigorous patient evaluation and a detailed patient history, including short and long term medication use, is the likely key to reducing any risk of cardiac arrhythmias associated with macrolides and fluoroquinolones. Clinicians should be cautious when prescribing macrolide and fluoroquinolone medications to patients with risk factors that may lead to antibiotic-induced cardiac arrhythmias, including a slow heart rate and those that are taking medications to treat arrhythmias.

Pharmacology of Antiemetics: Update and Current Considerations in Anesthesia Practice.

Postoperative nausea and vomiting (PONV) is associated with delayed recovery and dissatisfaction after surgical procedures. A key component to management is identifying risk factors and high-risk populations. Advances in pharmacologic therapeutics have resulted in agents targeting different pathways associated with the mediation of nausea and vomiting. This review focuses on these agents and the clinical aspects of their use in patients postoperatively. Combination therapies are reviewed, and studies demonstrate that when 2 or more antiemetic agents acting on different receptors are used, an overall improved efficacy is demonstrated when compared with a single agent alone in patients.

Characteristics and genotype profiles of antiretroviral-naïve patients entering a Southern US HIV outpatient clinic 2009-2012.

The US city of New Orleans was ranked second in the nation for estimated HIV case rates in 2011. Opt-out testing was established at the Interim Louisiana Hospital in New Orleans in 2013. The majority of new diagnoses were referred to the HIV outpatient program. We conducted a retrospective chart review of newly referred antiretroviral-naïve patients establishing HIV care between January 2009 and June 2013 to characterise demographic and genotype profiles to assist in clinical management and needed services. Of the eligible 226 patients, 68% were men, and 88% were African American. Nearly half of the study patients were younger than 35 years of age. Forty-six percent had an initial CD4 count <200 cells/mm(3), and 39% had a HIV viral load >100,000 copies/mL. The antiretroviral class with the most common major mutation was the non-nucleoside reverse transcriptase inhibitors (NNRTIs) where K103N was the most common major NNRTI mutation at presentation. We observed that male patients showed more advanced disease with later presentation to care, confirming the need for earlier HIV diagnosis. When considering initial antiretroviral therapy, baseline genotype information is encouraged, particularly if considering a NNRTI-based regimen.
