Background: Extravasation, the inadvertent leakage of intravenous (IV) medication from the vein into the surrounding tissue, is a iatrogenic cause of patient injury. Extravasation has been reported to occur in 0.1% to 6.5% of hospital inpatients. The incidence may be higher among children because they have multiple risk factors, including small and fragile veins, decreased peripheral circulation, capillary leakage, and flexible subcutaneous tissue.

Drug-resistant Mycobacterium tuberculosis (TB) infection represents a serious and growing problem. For patients infected or suspected of being infected with multidrug or extensively drug-resistant TB, several medications have to be given simultaneously for prolonged periods. Here, we review the literature on treatment and monitoring of adverse effects of pediatric drug-resistant TB therapy in a high resource, low TB burden setting.

The institution's methadone protocol was not followed consistently during the study period, and practices for transitioning from morphine by continuous IV infusion to methadone with tapering were also inconsistent. Further studies are needed to determine the optimal conversion ratio for morphine to methadone and the optimal tapering regimen to minimize withdrawal symptoms and adverse events.

Objective: To describe current stress ulcer prophylaxis practice in Canadian PICUs. Design: Multicenter cohort study. We defined stress ulcer prophylaxis as the use of a proton-pump inhibitor, histamine-2 receptor antagonist, or sucralfate within the first 2 PICU days among children who had not been on these medications at home and had no evidence of gastrointestinal bleeding. Setting: Seven PICUs in Canada. Patients: Three hundred seventy-eight children requiring mechanical ventilation. Interventions: None. Measurements and Main Results: Children were ventilated for a median (interquartile range) of 2 days (1–6 d) and stayed in the PICU for a median (interquartile range) of 4 days (2–10 d). The median (interquartile range) age was 1.3 years (0.3–6.7 yr). Seventy percent of all children received acid suppression during their PICU stay. One hundred sixty-seven (54%) of the 309 children eligible for stress ulcer prophylaxis received it. Histamine-2 receptor antagonists were the most frequently used class (66%), followed by proton-pump inhibitors (47%) and sucralfate (4%), and 20% received more than one class. Stress ulcer prophylaxis was continued on the PICU transfer orders for 34% of these children. Children who received prophylaxis were older and had a higher Pediatric Risk of Mortality III score, more often received nonsteroidal anti-inflammatory drugs and systemic corticosteroids and received less enteral nutrition. In multivariate analysis, age and invasive mechanical ventilation were independently associated with an increased likelihood of receiving stress ulcer prophylaxis and receiving feeds was independently associated with a decreased likelihood of receiving stress ulcer prophylaxis. Gastrointestinal bleeding was reported in 21 (6%) of 378 children; three (0.8%) were clinically important. Eighteen percent were treated for a new respiratory tract infection, and 1% developed Clostridium difficile–associated diarrhea. Conclusions: Stress ulcer prophylaxis is common in Canadian PICUs. Clinically important gastrointestinal bleeding and C. difficile–associated diarrhea are rare, and the utility of routine prophylaxis should be examined.

OBJECTIVE: Pro re nata (PRN) antipsychotics and benzodiazepines are routinely used for the rapid stabilization of acutely agitated patients. Despite the popular use of PRN medications in mental health units, primary literature supporting efficacy and safety is poor, and there is no single universally accepted practice guideline. PRN psychotropic medications have the potential to cause adverse effects when used inappropriately. AIMS: Our objective was to characterize the prescribing, administration, and documentation practices of PRN psychotropic medications in a psychiatric intensive care unit. METHODS: We conducted a retrospective chart review of patients admitted to a 12-bed psychiatric intensive care unit between June and September 2018. All PRN antipsychotic and benzodiazepine orders, administrations, documentation practices, and attempted nonpharmacological strategies were assessed for each order and patient. Descriptive statistics were used to analyze data. RESULTS: Thirty-two patients with a total of 123 physicians’ orders and 1,179 PRN administrations of antipsychotics and benzodiazepines were reviewed. Of the total administrations, 720 (61%) were combinations with at least two psychotropic agents. Forty-one (33%) physicians’ orders had a prescribed indication, and 559 (47%) administrations had an attempted nonpharmacological method prior to PRN administration. Eight patients (25%) had antipsychotic PRN orders, which exceeded the total daily maximum dose. Three adverse drug effects were attributed to PRN administration. CONCLUSIONS: Areas of improvement that we identified included documentation practices of effectiveness of administered PRNs, prescriptions to include clear indications and dosage within the 24-hour maximum limits, and documentation of nonpharmacological methods utilized.
