Objective This study aimed to compare the impact of saline lock to running a slow continuous infusion to-keep-vein-open (TKVO) on the total time a peripheral intravenous (PIV) catheter remained patent. Method A retrospective chart review of all children admitted to the paediatric ward of a regional hospital in Saskatchewan December 1, 2013 through February 28, 2014. Characteristics of patients with PIV catheters were abstracted from the health records, including patient size, catheter size and site, and total time each PIV catheter spent (i) infusing therapeutic fluids or medications, (ii) running a TKVO infusion, or (iii) saline locked. The duration of catheter patency was compared with the proportion of time that TKVO infusions were run, as well as patient gender and age. Results During 375 admissions, there were 189 PIVs which met inclusion criteria. The proportion of nontherapeutic time a PIV catheter spent TKVO compared to saline locked did not affect the total time the PIV catheter was patent (P=0.33). Gender had no influence, but older age, a nonmodifiable factor, was associated with increased time a PIV catheter remained patent (P=0.028). Discussion Peripheral intravenous (PIV) catheter insertion can be a painful and traumatic procedure. On the paediatric ward of a regional hospital, TKVO infusions were not superior to saline lock for prolonging PIV catheter patency.
Background Children with severe pancreatitis may require pancreatectomy, resulting in insulin-dependent diabetes. Our center has provided pediatric pancreatectomy with islet autotransplantation (PIAT) since 2003 to preserve pancreatic endocrine function and potentially prevent diabetes. We describe our experience with postoperative glycemic management after pediatric PIAT to provide guidance for future management. Method: We reviewed inpatient records for children who underwent PIAT. Data collected included age, indication for pancreatectomy, islet mass infused and details on insulin and nutritional support requirements. Descriptive analysis was performed. Results Twelve pediatric patients have undergone PIAT at our centre, with mean age 12.4 years (range 2.5-18.9) and mean duration of post-operative hospitalization 25 days (range 9-60). Indications for pancreatectomy included ten patients with chronic pancreatitis due to mutations in PRSS1, SPINK1, or CFTR, 1 patient due to trauma, and 1 patient due to tumor. Ten patients underwent total pancreatectomy, and 2 had partial pancreatectomies. Mean islet mass infused per body weight was 5867 IEQ/kg (range 1630-10276). Two patients did not receive insulin during hospitalization. The remaining ten required insulin, with mean maximum total daily dose of 0.9 u/kg/day (range 0.14-1.88). Total daily doses were higher while on parenteral nutrition (mean 0.75 versus 0.27 u/kg/day on days without parenteral nutrition). Duration of insulin therapy was also longer in patients who received parenteral nutrition (mean 25 versus 4 days). Six of the insulin-treated patients were able to discontinue insulin prior to discharge, with mean duration of insulin therapy 13 days (range 1-40). Four remained on insulin at discharge, with a mean total daily dose of 0.46 u/kg/day (range 0.12-0.82). Patients who were on insulin at discharge all had total pancreatectomies, were older (mean 17 versus 9 years), and had smaller islet mass per kilogram infused (mean 2718 versus 8116 IEQ/kg) compared to those not on insulin. Discussion We report our center's experience with PIAT. Seven of twelve patients were insulin-independent at discharge, and the remainder needed modest doses. Previous publications on islet autotransplantation have also demonstrated favourable outcomes in children, with insulin independence rates up to 82%1. Younger age and larger islet mass infused per kilogram predicted insulin independence in our cohort, similar to the findings of Chinnakotla et al2. In addition, our study suggests that feeding difficulties requiring parenteral nutrition increase daily insulin requirements and prolong the need for insulin therapy. References: 1.
