Parent/Nurse-Controlled Analgesia Compared with Intravenous PRN Opioids for Postsurgical Pain Management in Children with Developmental Delay: A Randomized Controlled Trial

PCA-pump for analgesia following pediatric scoliosis surgery: bolus administration with/without basal infusion

OBJECTIVES

The aim of this study is to compare the use of two different opioid delivery systems (bolus PCA with/without basal infusion) to control postoperative pain and evaluate the side effect profile in pediatric patients undergoing scoliosis surgery.

PATIENTS AND METHODS

38 patients who underwent posterior spinal fusion for adolescent idiopathic scoliosis were included in the study. Patients were randomly divided into 2 groups by the computer. Patients who received only bolus PCA were named Group 1, and patients who received bolus PCA with basal infusion were named Group 2.Morphine consumption, postoperative pain assessmentduring rest, movement and coughing with numeric rating scale (NRS) and the Wong -Baker pain scale, heart rate and average blood pressure, sedation levels withRamsey sedation scale and side effects such as nausea, vomiting, itching, desaturation, and urinary retention were recorded.

RESULTS

Total mean morphine consumption (mg) was 32.7 ± 9.7 in Group 1 and 43.4 ± 9.1 in Group 2. The mean morphine consumption (mg) at 12-24 hours and 0-48 hours in Group 1 was statistically lower than Group 2 (p = 0.001). There was no significant difference between the groups in terms of median NRS scores (p = 0.55). There was no statistically significant difference in the evaluation of the groups in terms of Wong-Baker pain scale. Wong-Baker pain scale is p:0.66 at the 2nd hour, p:0.951 at the 12th hour and p:0.467 at the 24th hour.There was no statistically significant difference in Ramsay Sedation Scale evaluation between groups during each follow-up time (p > 0.05). The Ramsay Sedation Scale was p: 0.94 at the 2nd hour, p:1.0 at the 12th hour, and p:1.0 at the 24th hour. The duration of vomiting between 0-2 h, 2-24 h and 0-48 h was higher in Group 2 (p = 0.001, p = 0.024, p = 0.001).

CONCLUSION

The two administration settings of morphine sulphate by PCA pump have shown to be equally effective in the treatment of postoperative pain following PSF. In addition, PCA with basal infusion administration causes more opioid consumption and more systemic side effects. Therefore, the use of only bolus PCA in pediatric scoliosis surgery should be encouraged.

A PRISMA Systematic Review on the Safety and Efficacy of Patient-Controlled Analgesia (PCA) in Pediatrics

PROBLEM

Effective pain management is the key to improving not only patient outcomes but also patient satisfaction. Patient controlled analgesia (PCA) is a pain management method that allows the patient to self-administer their medication. Because of the great variety of physical and cognitive abilities in the pediatric population, involvement of a nurse or parent proxy is necessary.

PURPOSE

The purpose of this study was to ascertain the most effective approaches to PCA in pediatric settings.

ELIGIBILITY CRITERIA

Criteria for articles selection were as follows: (a) published in a peer-review journal, (b) between 2014 and 2019, (c) in English, (d) directly addressing the issues of safety and efficacy of patient-controlled analgesia by proxy in the pediatric patient population.

SAMPLE

Databases used in the search included CINAHL Plus with Full Text, DynaMed, MedLine with Full Text, and ScienceDirect. Combinations of the following keywords were used to search each database: "nurse controlled analgesia", "parent controlled analgesia", "patient controlled analgesia by proxy", "NCA", "P/NCA", "PCA by proxy", "pediatrics", "children", "pediatric patients". Database searches yielded 172 results. Articles that were duplicated, missing inclusion criteria or did not directly address the issues of safety and efficacy of PCA by proxy were removed. Eleven articles fit the selection criteria.

RESULTS

Eleven articles were included in the final report. The themes that emerged from the analysis included pain management of neonates and infants, children with developmental disabilities, children with cancer, as well as the sources and possible solutions to errors in medication preparation.

CONCLUSIONS

It was concluded that PCA by proxy remains a safe and efficient method of pain administration for the pediatric population, with the exception of children suffering from developmental and neurological disabilities.

IMPLICATIONS

PCA by proxy, although presenting challenges, remains a safe and efficient way of pain management across different pediatric populations, such as infants and neonates or children with cancer, both inpatient and outpatient, and new technologies could positively influence the safety of this method of pain management. Conversely, children with developmental and neurological disabilities do not benefit from this method of pain management and are more prone to experiencing adverse effects.

Investigating the Effects of Cuing Medication Availability on Patient-controlled Analgesia Pump Usage in Pediatric Patients: Results of a Randomized Controlled Trial

OBJECTIVES

The study of patient-controlled analgesia (PCA) behaviors has led to a greater understanding of factors that affect the pain experience. Although PCA behaviors can be influenced by cues to medication availability, no studies have examined the effects of such cues in pediatric populations.

MATERIALS AND METHODS

This randomized controlled trial examined patient satisfaction with pain management, PCA behaviors, opioid consumption, and state anxiety in a sample of 125 postsurgical children and adolescents (7 to 17 y). Patients were randomized to a "light" group (lockout period status cued by light on the PCA button) or control group (no cues to medication availability).

RESULTS

Although cuing did not affect patient satisfaction with pain management (P=0.11), patients in the light group consumed significantly more opioid than those in the control group (adj. P=0.016). This effect was primarily because of children in the light group (median, 0.019; interquartile range, 0.012 to 0.036 mg/kg/h) consuming more opioid than children (12 y or younger) in control group (median, 0.015; interquartile range, 0.006 to 0.025 mg/kg/h) (P=0.007). In contrast to the control group, for patients in the light group, opioid consumption was unrelated to pain and the proportion of patients with a 1:1 injections:attempts ratio was higher (P<0.001) across the study period.

DISCUSSION

The overall pattern of results suggests that patients in the light group used their PCA in response to the light more than in response to their pain, which likely reflects operant influences on PCA behavior by pediatric patients.

A Pilot Randomized Controlled Trial of Outcomes Associated with Parent-Nurse Controlled Analgesia vs. Continuous Opioid Infusion in the Neonatal Intensive Care Unit

PURPOSE

Prospectively compare parent/nurse controlled analgesia (PNCA) to continuous opioid infusion (COI) in the post-operative neonatal intensive care unit (NICU) population.

DESIGN/METHODS

A randomized controlled trial compared neonates treated with morphine PNCA to those treated with morphine COI. The primary outcome was average opioid consumption up to 3 post-operative days. Secondary outcomes included 1) pain intensity, 2) adverse events that may be directly related to opioid consumption, and 3) parent and nurse satisfaction.

RESULTS

The sample consisted of 25 post-operative neonates and young infants randomized to either morphine PNCA (n = 16) or COI (n = 9). Groups differed significantly on daily opioid consumption, with the PNCA group receiving significantly less opioid (P = .02). Groups did not differ on average pain score or frequency of adverse events (P values > .05). Parents in both groups were satisfied with their infant's pain management and parents in the PNCA group were slightly more satisfied with their level of involvement (P = .03). Groups did not differ in nursing satisfaction.

CONCLUSIONS

PNCA may be an effective alternative to COI for pain management in the NICU population. This method may also substantially reduce opioid consumption, provide more individualized care, and improve parent satisfaction with their level of participation.

CLINICAL IMPLICATIONS

Patients in the NICU represent one of our most vulnerable patient populations. As nurses strive to provide safe and effective pain management, results of this study suggest PNCA may allow nurses to maintain their patients' comfort while providing less opioid and potentially improving parental perception of involvement.
