Bedside Postpyloric Tube Placement and Enteral Nutrition Delivery in the Pediatric Intensive Care Unit.

Nutr Clin Pract 2020 Apr 28;35(2):299-305. Epub 2020 Jan 28.

Department of Anesthesiology, Critical Care and Pain Medicine, Boston, Massachusetts, USA.

Background: Enteral nutrition (EN) delivery may be more effective via a postpyloric (PP) feeding tube in critically ill children, but tube placement can be challenging. We aimed to describe PP tube placement and EN practices in a multidisciplinary pediatric intensive care unit (PICU) after the implementation of a nurse-led bedside PP tube-placement program.

Methods: In a single-center retrospective study, we identified 100 consecutive patients admitted to the PICU for >48 hours and for whom PP tube placement was attempted. Demographics, clinical characteristics, and details of PP tube placement and EN delivery were examined.

Results: The study cohort had a median age (25th, 75th percentiles) of 3.89 years (0.55, 14.86); 66% were male. Respiratory illness was the primary diagnosis of admission (55%); 92% were on respiratory support. Risk of aspiration was the primary indication for PP tube placement (48%). Bedside placement was the initial technique for PP tube placement in 93% of patients (successful for 84.9%) and was not associated with serious complications. Eighty-seven patients with a PP tube started EN and received a median 73.9% (12.3%, 100%) of prescribed energy goal on day 3 after EN initiation. PP EN allowed 14 of 39 patients receiving parenteral nutrition (PN) to transition off PN 7 days after EN initiation. Thirty-five percent of EN interruptions were due to feeding-tube dysfunction.

Conclusion: Bedside PP tube placement is safe and feasible and allows for effective EN delivery and decreased PN use when applicable. Interruptions in PP EN due to tube malfunction are prevalent.

Pediatric Withdrawal Identification and Management.

J Pediatr Intensive Care 2015 Jun;4(2):73-78

Department of Cardiovascular/Critical Care Nursing, Medical Surgical Intensive Care Unit, Boston Children's Hospital, Boston, Massachusetts, United States.

Sedation administered by continuous intravenous infusion is commonly used in the pediatric intensive care unit to facilitate and maintain safe care of children during critical illness. Prolonged use of sedatives, including opioids, benzodiazepines, and potentially other adjunctive agents, is known to cause withdrawal symptoms when they are stopped abruptly or weaned quickly. In this review, the common signs and symptoms of opioid, benzodiazepine, and dexmedetomidine withdrawal will be discussed. Current tools used to measure withdrawal objectively, as well as withdrawal prevention and management strategies, will be discussed.

Coordination of multiple services for a patient with severe lymphedema of the right lower extremity.

Crit Care Nurse 2011 Aug;31(4):55-68

Vascular Anomalies Center, Children’s Hospital Boston, Massachusetts, MA 02115, USA.

Surgical resection of the right lower extremity in an adult with severe lymph-edema of the extremity required intensive coordination of multiple services and specialists because of the medical and surgical complexity of the patient's condition, massive limb size, and surgical location in a children's hospital. Early and prolonged planning was necessary to anticipate problems and provide optimal care. The patient had a successful surgical outcome, improvement in medical comorbid conditions postoperatively, and improvement in the quality of life upon discharge. This coordinated effort will be used in the future as a template for patients with complex conditions whose care requires lengthy planning and involves multiple services and specialists.

Preventing corneal abrasions in critically ill children receiving neuromuscular blockade: a randomized, controlled trial.

Pediatr Crit Care Med 2009 Mar;10(2):171-5

Children's Memorial Hospital, Chicago, IL, USA.

Objective: To determine the incidence of corneal abrasions in critically ill children requiring neuromuscular blockade (NMB) and to determine whether a moisture chamber over the eye is more effective in preventing corneal abrasions compared with standard therapy.

Design: Randomized controlled clinical trial.

Setting: Three pediatric intensive care units at two free-standing, university-affiliated children's hospitals.

Patients: Consecutive intubated, mechanically ventilated patients receiving NMB <36 hours, 2 weeks to 18 years of age.

Intervention: After confirming the absence of a corneal abrasion, patients' eyes were randomized to either control (Q6H lubrication and eye closure) or treatment (Q6H lubrication, eyelid closure and moisture chamber). Eyes were examined daily for 3 days then every other day until NMB was discontinued, a corneal abrasion developed, or on study day 9. Data were analyzed on an intention-to-treat basis.

Measurements And Main Results: Two hundred thirty-seven patients were enrolled. Thirty patients exited the study before randomization (17 upon confirmation of a corneal abrasion on initial examination [7%; 95% confidence interval 4%-11%]; 12 upon discontinuation of NMB; 1 patient death). The remaining 207 patients were randomized and evaluated twice (median; interquartile range [IQR] 1-4 observations). Twenty-one patients developed a corneal abrasion over the course of the study (10%; 95%confidence interval 6%-15%). Median time from enrollment to abrasion was 2 days (IQR 1-3 days). The incidence of corneal abrasion was not different between the patient's control and treatment eyes; specifically, eight corneal abrasions developed in the control eye, five corneal abrasions in the treatment eye, and eight corneal abrasions in both eyes (McNemar's test; p = 0.58).

Conclusions: The occurrence of corneal abrasions in critically ill children receiving NMB is not trivial. The additional use of a moisture chamber over the eye was no more effective than Q6H lubrication and eye closure alone in preventing corneal abrasions in this at-risk patient group.
