Opioid prescription patterns in a children's hospital from 2012 to 2016.

STUDY OBJECTIVE: Pain management is a widely discussed topic, especially in the setting of the current opioid epidemic. Previous studies have shown that the use of opioids increased in the adult population. We aimed to look at the use of narcotic and non-narcotic pain medications at a large pediatric hospital to discern if patterns of pediatric pain management changed over time. METHODS: 58,402 analgesic prescriptions of patients 0-21 years of age were analyzed from May 2012 to November 2016. A logistic regression model was fitted to examine the association of age, sex, primary diagnosis, and the length of hospital stay with probability of opioid prescription. RESULTS: 36,560 patients aged 0-21 years (mean: 10.5, median: 11.0, and standard deviation (SD): 7.42) received analgesic pain medications. 21,847 (59.8 percent) patients were prescribed more than one analgesic. There was a male predominance in patients <15 years of age; however, in adolescents >16 years, females constituted 57.1 percent of patients. Data also showed a statistically significant reduction of opioid prescriptions from 2012 to 2016 (p < 0.001). Age and length of hospital stay were directly associated with opioid prescription (p < 0.001). CONCLUSION: Data show that there is a decrease in overall opioid prescriptions among pediatric patients, which may be secondary to new Food and Drug Administration regulations and increased awareness of morbidity associated with opioid use. Not surprisingly, increased hospital stay and increase in age lead to more analgesic prescriptions. Further investigation is needed to determine the differences within opioid prescription patterns.

Significance of measured intraoperative portal vein flows after thrombendvenectomy in deceased donor liver transplantations with portal vein thrombosis.

Adequate portal vein (PV) flow in liver transplantation is essential for a good outcome, and it may be compromised in patients with portal vein thrombosis (PVT). This study evaluated the impact of intraoperatively measured PV flow after PV thrombendvenectomy on outcomes after deceased donor liver transplantation (DDLT). The study included 77 patients over a 16-year period who underwent PV thrombendvenectomy with complete flow data. Patients were classified into 2 groups: high PV flow (>1300 mL/minute; n = 55) and low PV flow (≤1300 mL/minute; n = 22). Postoperative complications and graft survival were analyzed according to the PV flow. The 2 groups were similar in demographic characteristics. Low PV flow was associated with higher cumulative rates of biliary strictures (P = 0.02) and lower 1-, 2-, and 5-year graft survival (89%, 85%, and 68% versus 64%, 55%, and 38%, respectively; P = 0.002). There was no difference in the incidence of postoperative PVT between the groups (1.8% versus 9.1%; P = 0.19). No biliary leaks or hepatic artery thromboses were reported in either group. By multivariate analyses, age >60 years (hazard ratio [HR], 3.04, 95% confidence interval [CI], 1.36-6.82; P = 0.007) and low portal flow (HR, 2.31; 95% CI, 1.15-4.65; P = 0.02) were associated with worse survival. In conclusion, PV flow <1300 mL/minute after PV thrombendvenectomy for PVT during DDLT was associated with higher rates of biliary strictures and worse graft survival. Consideration should be given to identifying reasons for low flow and performing maneuvers to increase PV flow when intraoperative PV flows are <1300 mL/minute.

Surgical repair of renal artery aneurysms.

The pathogenesis of renal artery aneurysms (RAAs) is degenerative, which eventually leads to weakening of the vessel wall and, in extreme cases, rupture. RAAs are a rare occurrence. Patients generally are asymptomatic, with a small number presenting with uncontrollable hypertension or hematuria. Most RAAs are discovered incidentally on imaging and do not pose an immediate health threat. However, the risk of rupture is an indication for prophylactic repair in certain patients. Interest in interventional radiologic procedures in the management of RAAs has recently increased; however, open repair should still be considered in select instances. In this case series, we present three patients for whom an open approach was indicated and performed.
