Feasibility of Nurse-Managed Tobacco Use Interventions in Outpatient Surgical Practice.

PURPOSE: The aim of this study was to determine the feasibility of developing and implementing a brief nurse-delivered tobacco intervention in an outpatient surgical practice. DESIGN AND METHODS: Initial formative work used a survey and focus groups to determine knowledge, attitudes, and practices of perioperative nurses working in three outpatient surgical practices regarding smoking use and cessation. Based on this work, a brief intervention was designed and implemented in one of the three practices. The documentation of tobacco use and intervention elements was assessed both immediately and approximately 9 months after implementation. FINDINGS: Formative work identified not only several barriers to implementation and little current activity but also favorable attitudes toward interventions. Implementation improved self-efficacy for intervention delivery and compliance with documentation of intervention elements that was sustained for at least 9 months. CONCLUSIONS: Our results suggest that it is feasible for perioperative nurses to play an important role in the delivery of perioperative tobacco interventions.

Examining Use of Low-Dose Ketamine Infusions During the Postoperative Period: A Retrospective Study Comparing Opioid-Tolerant and Nonopioid-Tolerant Patients.

Ketamine is a well-known anesthetic that has been used since the 1970s. Despite its ubiquitous use as a postoperative analgesic, no studies have described dosing differences between opioid-tolerant (OT) and nonopioid-tolerant (NOT) patients or determined optimal dosing. The primary aim of this study was to assess whether OT and NOT patients had significant differences in ketamine infusion dosing requirements. We also aimed to measure the overall incidence of psychotomimetic adverse effects associated with low-dose ketamine infusions. We hypothesized that NOT patients would have lower ketamine infusion dosing requirements and a higher incidence of psychotomimetic adverse effects compared with OT patients. We performed a retrospective chart review and showed that the percentages of OT and NOT patients experiencing psychotomimetic adverse effects were similar (15.5% vs 15.3%; P=.93) and that increasing age was the only factor associated with increased odds of experiencing a psychotomimetic adverse effect potentially associated with ketamine (odds ratio, 1.29 [95% CI, 1.11-1.50]; P=.001). Optimal subanesthetic ketamine infusion dosing could not be established, and further research in this area may be warranted.

Correction to: The Role of Aprepitant in Prevention of Postoperative Nausea and Vomiting After Bariatric Surgery.

In the section "Discussion" on page 41, the second sentence in the second paragraph in the right-hand column should read as follows.

Delirium in Postoperative Patients Admitted to the Intensive Care Unit.

Postoperative delirium (POD) is common among surgical patients admitted to the intensive care unit (ICU) and is associated with increased resource utilization, morbidity, and death. Our primary aim was to compare rates of POD using administrative International Classification of Diseases, Ninth Revision, records and automated interrogation of electronic health records from Confusion Assessment Method for the ICU (CAM-ICU) screening. The secondary aim was to assess POD risk associated with patient and perioperative characteristics. Electronic health records of surgical patients admitted to the ICU during 2011 through 2014 were abstracted for POD assessment by CAM-ICU and by administrative codes, Charlson comorbidity index, surgical characteristics, and Acute Physiology, Age, Chronic Health Evaluation III scores. Of 6338 patients, CAM-ICU identified 606 (9.6%) and administrative records identified 55 (0.9%) POD cases, with agreement on 50 cases. In multivariable logistic regression based on POD identified with CAM-ICU, preexisting dementia had the strongest association with POD (odds ratio [95% confidence interval], 6.47 [3.68-11.37]; P < 0.001). Other associations found were older age, congestive heart failure, chronic pulmonary disease, increased surgical duration, emergency cases, blood transfusions, postoperative ventilation, and higher Acute Physiology, Age, Chronic Health Evaluation III scores (all P ≤ 0.01). POD cases had lengthier ICU and hospital stays and a higher mortality rate (all P < 0.001). CAM-ICU scores identified higher rates of POD than a search for POD based on administrative codes. Preoperative presence of dementia and major comorbidities were associated with POD. Delirium in surgical patients is associated with worse outcomes.

The Role of Aprepitant in Prevention of Postoperative Nausea and Vomiting After Bariatric Surgery.

BACKGROUND: Postoperative nausea and vomiting (PONV) is common with bariatric surgery. We examined the PONV rate in bariatric surgical patients who received triple antiemetic prophylaxis (dexamethasone, droperidol, and ondansetron) with and without antiemetic aprepitant. METHODS: Medical records of female patients undergoing laparoscopic bariatric surgery from January 1, 2014, to July 28, 2016, were reviewed for PONV episodes during 48 postoperative hours. RESULTS: In total, 338 patients received triple antiemetic, of whom 172 (51%) also received aprepitant. Rates of PONV in the postanesthesia care unit (PACU) among patients with and without aprepitant therapy were 11 vs 17% (P = .09). Within 1 h after PACU discharge, fewer patients in the aprepitant group had PONV (19 vs 31%; odds ratio [OR] [95% CI], 0.5 [0.30-0.80]; P = .007). During the first 48 postoperative hours, PONV rates were similar between the groups (68 and 66%; P = .73), but fewer emesis episodes occurred in the aprepitant group (6 vs 13%; OR [95% CI], 0.45 [0.21-0.95]; P = .04). Analyses were also performed with a subset of patients matched on propensity for receiving aprepitant. In this subset, OR estimates quantifying aprepitant effect on PONV were similar to those obtained from multivariable regression analyses. CONCLUSION: Addition of aprepitant to a multimodal antiemetic prophylactic regimen may be associated with significant reduction of PONV during early recovery and potentially with reduced incidence of vomiting during the first 48 postoperative hours. The high PONV rate in the first 48 postoperative hours is suggestive that introduction of scheduled anti-PONV prophylactic treatment may be desirable.

Anesthetic care of the trauma patient: development of a Web-based resource.

Adequate preparation by anesthesia providers promotes quality care and decreases the likelihood of morbidity and mortality. Unfortunately, many trauma cases occur after hours when support resources are less readily available. At a large midwest academic medical center, it was determined that a website on the institution's Intranet relating to anesthetic care of trauma patients would be a readily accessible, user-friendly resource for improved care. In recent years, media tools such as computers have become increasingly popular and accessible as effective learning tools. A comprehensive literature search was completed on anesthetic care of trauma patients and on adult and Web-based learning principles. Information was gathered from textbooks, research journals, existing web links on the institution's intranet, and staff at the medical center. Assistance was obtained from the institution's Internet/website Development Department for creation of the website. The information was placed on the institution's Intranet. The web page contains 17 subject categories, including initial considerations, common trauma drugs, circulation and fluid resuscitation, management of pregnant trauma patients, and intraoperative death. It is our goal that the systematic developmental process described in this article may provide a model for other institutions wanting to develop websites.
