Characterization of vitamin D deficiency and use of a standardized supplementation protocol in orthopaedic trauma patients.

PURPOSE: The objectives of this study were to assess the incidence of vitamin D deficiency in orthopaedic trauma patients, evaluate the safety and efficacy of a vitamin D supplementation protocol, and investigate the utility of vitamin D supplementation in reducing nonunions. METHODS: Three hundred seventy patients with operative tibia and/or fibula fractures were retrospectively reviewed. Both overall and matched cohorts were analysed. RESULTS: Ninety-eight per cent (n = 210) were found to have vitamin D insufficiency (serum 25(OH)D level < 30 ng/ml). There were no cases of vitamin D toxicity following vitamin D replacement. Median follow-up vitamin D level was 22.7 ng/mL. No statistical difference between union rates was found between either the two consecutive cohorts or matched cohorts. CONCLUSION: This vitamin D replacement protocol was a safe treatment for hypovitaminosis D, but post hoc analysis shows there would need to be over 1200 matched patients to achieve adequate power.

Utility of neuromuscular blockade reversal in the evaluation of acute neurosurgical patients: A retrospective case-series.

OBJECTIVE: Sugammadex reversal of neuromuscular blocking agents (NMBAs) is usually performed postoperatively. A scarcity of literature exists exploring sugammadex use for timely neurological examination of neurosurgical patients. NMBAs, like rocuronium, are used in the Emergency Department during intubation and their unpredictable duration of action often impedes timely and accurate assessment of patient neurological status. We aim to explore the role of sugammadex in evaluating patients in need of acute neurosurgical care. METHODS: Retrospective assessment of patients presenting with traumatic brain injury or intracranial hemorrhage was conducted at our level 1 trauma center. Patients of interest were those for whom sugammadex reversal of rocuronium neuromuscular blockade, from intubating doses, was pursued to ensure timely neurologic assessment. Nine patients were identified for whom GCS pre-/post-sugammadex, rocuronium dosing, elapsed time between rocuronium administration and reversal, and clinical course data were retrieved. RESULTS: Arrival GCS was 5.2 ± 3.2, with intubation accomplished within 10 ± 2.5 min of presentation. Rocuronium dosing was consistent between patients, average single dose of 1.2 ± 0.3 mg/kg. Lingering neuromuscular blockade ranged from 28 to 132 min (87.3 ± 34.3 min). All patients exhibited a GCS of 3 T upon initial neurosurgical evaluation, prior to reversal. Post-reversal GCS rose to 6.0 T ± 2.2. Sugammadex facilitated more accurate clinical decision making in 8 of 9 patients, including prevention of unnecessary invasive procedures. Two of 9 patients were eventually discharged home or to a rehabilitation facility. CONCLUSIONS: Rocuronium neuromuscular blockade can linger beyond pharmacokinetic predictions, thus delaying timely and precise neurologic assessment. Our data suggests sugammadex may be a useful addition to the clinician's armamentarium for acute neurologic assessment in the neurosurgical population. Sugammadex may impact clinical decision-making in certain patients and allow for more informed decision-making by families and physicians alike. Prospective studies are needed to definitively assess the impact of sugammadex on outcomes in acute neurosurgical settings.

Development of a pharmacist-managed protocol for the transition from intravenous to subcutaneous insulin in critically ill adults.

PURPOSE: To evaluate the efficacy and safety of a pharmacist-managed protocol for transitioning critically ill patients from intravenous (IV) to subcutaneous insulin. METHODS: This single-center, retrospective, observational study included patients admitted to the medical or surgical/trauma intensive care unit who received a continuous infusion of IV insulin from January 2019 to April 2021. Patients were excluded if they were less than 18 years old, pregnant, or incarcerated or received IV insulin for the diagnosis of diabetic ketoacidosis, hyperglycemic hyperosmolar state, calcium channel blocker or ß-blocker overdose, or hypertriglyceridemia. The primary outcome was to evaluate the percentage of blood glucose (BG) concentrations within the target range of 70 to 150 mg/dL within 48 hours of the transition to subcutaneous insulin. Secondary outcomes included the percentage of BG concentrations within the goal range following transition at 0 to 12 hours and 12 to 24 hours, the incidence of hypo- and hyperglycemia, and the percentage of patients requiring dose adjustments after the initial transition. RESULTS: Pharmacists were able to achieve BG concentrations in the target range for 53% of transitions at 12 hours, 40% of transitions at 24 hours, and 47% of transitions at 48 hours. With respect to safety endpoints, the pharmacist-managed group had a low rate of hypoglycemia (1.0%) and no severe hypoglycemia. Hyperglycemia was reported for 28% of BG concentrations while severe hyperglycemia was reported for 27%. Pharmacists transitioned patients to an average of 63% of the 24-hour total daily dose of insulin as basal insulin. CONCLUSION: Pharmacists can effectively and safely transition critically ill patients from IV to subcutaneous insulin utilizing a standardized protocol.
