Perioperative methadone for posterior spinal fusion in adolescents: Results from a double-blind randomized-controlled trial.

BACKGROUND: Posterior spinal fusion is the most common surgical procedure performed for correction of adolescent idiopathic scoliosis in the United States. Intraoperative methadone has been shown to improve pain control in adult patients undergoing complex spine surgery, and current pediatric studies show encouraging results; however, prospective randomized-controlled trials are lacking in the pediatric literature. AIMS: We conducted a single-center double-blind randomized-controlled trial to compare intraoperative use of methadone to morphine in pediatric patients undergoing posterior spinal fusion. METHODS: A total of 47 adolescents undergoing posterior spinal fusion were randomized (stratified by sex) to either a methadone (n = 25) or morphine (n = 22) group. The primary outcome was postoperative opioid consumption. Secondary outcomes included postoperative pain severity, opioid-related side effects, and ratio of patient-controlled analgesia injections: attempts as a behavioral index of uncontrolled pain. RESULTS: Patients in the methadone group consumed less total opioid postoperatively (median [interquartile range], 0.3 mg/kg [0.1, 0.5]) than patients in the morphine group (0.3 mg/kg [0.2, 0.6]), median difference [95% confidence interval] -0.07 [-0.2 to 0.02]; (p = .026). Despite the lower amount of opioid used postoperatively, pain scores for the methadone group (3.5 [3.0, 4.3]) were not significantly different from those in the morphine group (4.0 [3.2, 5.0]; p = .250). Groups did not differ on opioid-related side effects. CONCLUSIONS: A two-dose intraoperative methadone regimen resulted in decreased opioid consumption compared to morphine. Although the clinical significance of these results may be limited, the analgesic equipoise without increased opioid-related side effects and potential for a lower incidence of chronic pain may tip the balance in favor of routine methadone use for adolescents undergoing posterior spinal fusion.

Stress Numerical Rating Scale-11: Validation in Pediatric Inpatient and Outpatient Pain Settings.

Stress is a commonly reported issue in pediatric populations of chronic and acute pain. Both outpatient and inpatient settings impose time constraints, which decreases opportunities to measure and address patient stress. The aim of these studies was to evaluate the validity of the Stress Numeric Rating Scale-11 (SNRS-11) in both inpatient and outpatient settings. The SNRS-11 is a single item stress measure ranging from 0 to 10 with endpoint anchors: 0 = "No stress" and 10 = "Highest stress possible". Results showed discriminative validity in the inpatient sample and convergent and discriminant validity in both outpatient and inpatient samples. Additionally, approximately 40% to 50% of the sample reported moderate-severe stress on all post-operative days. The SNRS-11 shows promise as a quick, easy, and free stress measure to be used in both inpatient and outpatient settings.

Use of Aromatherapy for Pediatric Surgical Patients.

BACKGROUND: Children having surgery experience distress from a myriad of sources. Aromatherapy may present an opportunity to promote a healing environment and decrease distress for children following surgery. AIM: Evidence regarding the use of aromatherapy with children is growing. The purpose of this project was to describe our implementation process, subsequent use of and response to aromatherapy for children undergoing surgery. METHODS: This quality improvement project and subsequent retrospective chart review included all patients with documentation of aromatherapy use over an 8-month period. Data collection included demographic data, patient diagnosis, location, information about which oils were used, for which indications, and any outcome the nurse was able to observe (e.g., improved, no change, worsening of symptoms). A nurse-led workgroup developed and implemented a process for aromatherapy in a limited scope when discomfort, nausea/vomiting, nervousness, and sleep disturbances were reported . Charts of all patients with documented aromatherapy use were reviewed for indication/reason for use, oil, and patient response. RESULTS: Results suggest a successful implementation process. Aromatherapy was used by 191 patients (aged 3-22 years). Upset stomach, discomfort, and nervousness were most frequently reported as leading to aromatherapy use. Lavender and peppermint were the most frequently used oils. Of those patients with documented responses, the majority reported improvement. CONCLUSIONS: We were able to successfully implement a new aromatherapy program as an adjunct to care in children undergoing surgery. No adverse events were reported. Documentation is crucial to evaluating any new service.

Pediatric healthcare professionals' perceptions, knowledge, and use of essential oils.

OBJECTIVES: Complementary and Integrative Medicines (CIM) are widely used by adults and children. Despite this, studies have shown that Healthcare Professionals' (HCPs) views about CIM vary. Because underlying knowledge, perceptions and biases may influence HCPs' acceptance of a new aromatherapy program, the investigators sought to assess HCPs' views regarding aromatherapy before implementing an aromatherapy program in a pediatric hospital. DESIGNS AND MEASURES: A convenience sample of HCPs at an academic pediatric hospital in the United States completed an investigator developed online questionnaire about their perceptions, knowledge, and use of essential oils. RESULTS: The sample included 987 respondents, of which: 62.0% were nurses. Overall, 94.2% of HCPs indicated that they "rarely, never, or seldomly" discussed essential oil use with patients. Most indicated a willingness to incorporate essential oils into their patient care with appropriate education. Furthermore, 47.4% of HCPs reported positive views about the use of essential oils, 4.9% reported negative views and opinions, and 45% raised specific concerns about safety, education and/or evidence. CONCLUSION: Overall, this study suggests that HCPs have limited knowledge regarding essential oils, are open to learning more about them, and would like more evidence specifically regarding the efficacy and safety of using essential oils in pediatrics. Additionally, most HCPs are not currently discussing essential oils with pediatric patients. However, they are open to incorporating them into their patients' care if they receive proper education, and are open to our organization implementing an aromatherapy program if appropriate education and safety measures are provided.

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. STUDY TYPE: Treatment study. LEVEL OF EVIDENCE: I.

Barriers to Pediatric Pain Management: A Brief Report of Results from a Multisite Study.

BACKGROUND: Pain management is essential for the care of hospitalized children. Although multiple barriers have been identified that interfere with nurses' ability to provide optimal pain management, it is not known how pervasive are these barriers across the United States. AIMS: This study is the third in a series of studies examining barriers to pediatric pain management. The aim of this study was to examine barriers in different organizations using the same tool during the same period of time. SETTINGS/PARTICIPANTS: A sample of 808 nurses from three pediatric teaching hospitals responded to a survey addressing barriers to optimal pain management for children. RESULTS: Barriers unanimously identified as being most significant included inadequate or insufficient physician medication orders, insufficient time allowed to premedicate before procedures, insufficient premedication orders before procedures, and low priority given to pain management by medical staff. CONCLUSIONS: Barriers identified as the most and least significant were similar regardless of hospital location. Revealing similar barriers across multiple pediatric hospitals provides direction for nurses trying to provide solutions to these pain management barriers.

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

Objectives: The aim of this study was to conduct a randomized, controlled comparison of outcomes associated with parent/nurse-controlled analgesia (PNCA), with and without a basal (background) opioid infusion, with intravenous (IV) opioids intermittently administered by a nurse on an "as needed" basis (IV PRN) for postoperative pain management in children with developmental delay (DD). Methods: Participants included children with DD expected to require IV opioids for at least 24 postoperative hours. Patients were randomized to one of three groups: PNCA with a basal infusion, PNCA without a basal infusion, or IV PRN opioids. Demographics, pain scores, opioid consumption, and frequency of side effects were collected beginning 12 hours after emerging from anesthesia to decrease the impact of anesthetic agents on outcomes. Results: The 81 participants (median = 12.0, 9.0-15.0 years) were primarily Caucasian (74%) males (58%), with severe DD (69%) having spinal surgery (41%). The proportion of patients in each group with pain scores ≤3 vs ≥ 4 revealed no between-group differences in any epoch (P = 0.09-0.27). Patients in the PNCA with a basal group consumed significantly more opioid (median = 0.03 mg/kg/h morphine equivalents, 0.02-0.03 mg/kg/h) than the PNCA without a basal infusion. No difference was found between the PNCA without a basal (median = 0.01 mg/kg/h morphine equivalents, 0.00-0.02 mg/kg/h) and the PRN groups (median = 0.01 mg/kg/h morphine equivalents, 0.01-0.02 mg/kg/h). There were no statistically significant differences in side effects, with the exception that more children in the PNCA group required supplemental oxygen (P = 0.05). Conclusions: Results suggest there may be no advantage to PNCA over PRN opioids in this patient population after the first 12 postoperative hours with regard to pain scores, opioid consumption, or side effects.

Is there an alternative to continuous opioid infusion for neonatal pain control? A preliminary report of parent/nurse-controlled analgesia in the neonatal intensive care unit.

BACKGROUND: Continuous opioid infusion (COI) remains the mainstay of analgesic therapy in the neonatal intensive care unit (NICU). Parent/nurse-controlled analgesia (PNCA) has been accepted as safe and effective for pediatric patients, but few reports include use in neonates. This study sought to compare outcomes of PNCA and COI in postsurgical neonates and young infants. METHODS: Twenty infants treated with morphine PNCA were retrospectively compared with 13 infants treated with fentanyl COI in a Midwestern pediatric hospital in the United States. Outcome measures included opioid consumption, pain scores, frequency of adverse events, and subsequent methadone use. RESULTS: The PNCA group (median 6.4 µg · kg(-1) · h(-1) morphine equivalents, range 0.0-31.4) received significantly less opioid (P < 0.001) than the COI group (median 40.0 µg · kg(-1) · h(-1) morphine equivalents; range 20.0-153.3), across postoperative days 0-3. Average daily pain scores (based on 0-10 scale) were low for both groups, but median scores differed nonetheless (0.8 PNCA vs 0.3 COI, P < 0.05). There was no significant difference in the frequency of adverse events or methadone use. CONCLUSION: Results suggest PNCA may be a feasible and effective alternative to COI for pain management in postsurgical infants in the NICU. Results also suggest PNCA may provide more individualized care for this vulnerable population and in doing so, may potentially reduce opioid consumption; however, more studies are needed.

Do barriers to pediatric pain management as perceived by nurses change over time?

For decades, nurses (RNs) have identified barriers to providing the optimal pain management that children deserve; yet no studies were found in the literature that assessed these barriers over time or across multiple pediatric hospitals. The purpose of this study was to reassess barriers that pediatric RNs perceive, and how they describe optimal pain management, 3 years after our initial assessment, collect quantitative data regarding barriers identified through comments during our initial assessment, and describe any changes over time. The Modified Barriers to Optimal Pain Management survey was used to measure barriers in both studies. RNs were invited via e-mail to complete an electronic survey. Descriptive and inferential statistics were used to compare results over time. Four hundred forty-two RNs responded, representing a 38% response rate. RNs continue to describe optimal pain management most often in terms of patient comfort and level of functioning. While small changes were seen for several of the barriers, the most significant barriers continued to involve delays in the availability of medications, insufficient physician medication orders, and insufficient orders and time allowed to pre-medicate patients before procedures. To our knowledge, this is the first study to reassess RNs' perceptions of barriers to pediatric pain management over time. While little change was seen in RNs' descriptions of optimal pain management or in RNs' perceptions of barriers, no single item was rated as more than a moderate barrier to pain management. The implications of these findings are discussed in the context of improvement strategies.

Barriers to pediatric pain management: a nursing perspective.

This study describes strategies used by the Joint Clinical Practice Council of Children's Hospital of Wisconsin to identify barriers perceived as interfering with nurses' (RNs) ability to provide optimal pain management. A survey was used to ascertain how nurses described optimal pain management and how much nurses perceived potential barriers as interfering with their ability to provide that level of care. The survey, "Barriers to Optimal Pain management" (adapted from Van Hulle Vincent & Denyes, 2004), was distributed to all RNs working in all patient care settings. Two hundred seventy-two surveys were returned. The five most significant barriers identified were insufficient physician (MD) orders, insufficient MD orders before procedures, insufficient time to premedicate patients before procedures, the perception of a low priority given to pain management by medical staff, and parents' reluctance to have patients receive pain medication. Additional barriers were identified through narrative comments. Information regarding the impact of the Acute Pain Service on patient care, RNs' ability to overcome barriers, and RNs' perception of current pain management practices is included, as are several specific interventions aimed at improving or ultimately eliminating identified barriers.

Procedural pain management: a position statement with clinical practice recommendations.

The American Society for Pain Management Nursing (ASPMN) has developed a position statement and clinical practice recommendations related to procedural preparation and comfort management. Procedures potentially produce pain and anxiety, both of which should be assessed and addressed before the procedure begins. This position statement refers to "comfort management" as incorporating the management of pain, anxiety, and any other discomforts that may occur with procedures. It is the position of ASPMN that nurses and other health care professionals advocate and intervene based on the needs of the patient, setting, and situation, to provide optimal comfort management before, during, and after procedures. Furthermore, ASPMN does not condone procedures being performed without the implementation of planned comfort assessment and management. In addition to outlining this position with supporting evidence, this paper reviews the ethical considerations regarding procedural comfort management and provides recommendations for nonpharmacologic and pharmacologic management during all phases of the procedure. An appendix provides a summary of this position statement and clinical practice recommendations.

A preliminary report of parent/nurse-controlled analgesia (PNCA) in infants and preschoolers.

BACKGROUND: infants and young children are often unable to verbalize pain or advocate for themselves which may increase their risk for poor pain assessment and management. Although patient-controlled analgesia (PCA) has been shown to be safe, effective, and superior to intermittent opioid dosing, infants and young children are not able to operate PCA independently. Allowing a parent or nurse to operate the PCA for the child [parent/nurse-controlled analgesia (PNCA)] may be an option for these children. However, the use of PNCA has been heavily scrutinized and more evidence of safety is needed to support this practice. OBJECTIVES: the primary purpose of this study was to evaluate safety outcomes associated with PNCA for infants and preschool aged children. Secondary outcomes regarding the frequency of untoward side effects and clinical effectiveness were also examined. METHODS: a retrospective review of treatment with PNCA was conducted from a convenience sample of charts for 107 infants and preschoolers. Data were collected for 72 hours or until the PNCA was discontinued. RESULTS: one hundred and seven infants and preschoolers with a mean age of 19.6 months (±12.12) were represented in this study. Mean pain scores were low, as was the number of PNCA injections and attempts and amount of opioid administered. Common opioid side effects were reported. Naloxone was administered to 1.9% of patients for respiratory depression, and potential contributing factors were identified. DISCUSSION: diligent monitoring and education are crucial to ensure safety. Untoward side effects adverse events and pain scores suggest PNCA may be an effective method of pain control for this patient population.

Initial surgical and pain management outcomes after Nuss procedure.

PURPOSE: The purpose of this article was to report surgical and pain management outcomes of the initial Nuss procedure experience at the Children's Hospital of Wisconsin (Milwaukee) and to place this experience in the context of the published literature. METHODS: The initial 118 consecutive Nuss procedures in 117 patients were retrospectively reviewed with approval of the Children's Hospital of Wisconsin human rights review board. Patient, surgical, complication, and pain descriptors were collected for each case. Statistical methods for comparison of pain strategies included the Kolmogorov-Smirnov test for normality, 1-way repeated measures analysis of variance, and paired t tests. RESULTS: Patient, surgical, and complication descriptors were comparable to other large series. Complication rates were 7% early and 25% late. Epidural success rate was 96.4%. There was 1 episode of recurrence 2 years postbar removal (n = 114). CONCLUSIONS: The institution of the Nuss procedure provides a highly desired result with significant complication rates. The ideal approach would deliver this result with lower risk. A pain service-driven epidural administration of morphine or hydromorphone with local anesthetic provides excellent analgesia for patients after Nuss procedure. The success of epidural analgesia is independent of catheter site and adjunctive medications. Ketorolac was an effective breakthrough medication.

Gabapentin use in pediatric spinal fusion patients: a randomized, double-blind, controlled trial.

BACKGROUND: Gabapentin has opioid-sparing effects in adult surgical patients, but no reported studies have involved children and adolescents. In a double-blind, randomized, controlled trial, we examined whether gabapentin decreases postoperative opioid consumption for pediatric spinal fusion patients with idiopathic scoliosis. METHODS: Patients, aged 9 to 18 years, received preoperative gabapentin (15 mg/kg, treatment) or placebo. Anesthesia was standardized. After surgery, all patients received standardized patient-controlled analgesia opioid and continued on either gabapentin (5 mg/kg) or placebo 3 times per day for 5 days. Opioid use was calculated in mg/kg/time intervals. Pain scores and opioid side effects were recorded. RESULTS: Data from 59 patients (30 placebo and 29 gabapentin) did not differ in demographics. Total morphine consumption (mg/kg/h +/- SD) was significantly lower in the gabapentin group in the recovery room (0.044 +/- 0.017 vs 0.064 +/- 0.031, P = 0.003), postoperative day 1 (0.046 +/- 0.016 vs 0.055 +/- 0.017, P = 0.051), and postoperative day 2 (0.036 +/- 0.016 vs 0.047 +/- 0.019, P = 0.018). In addition, gabapentin significantly reduced first pain scores in the recovery room (2.5 +/- 2.8 vs 6.0 +/- 2.4, P < 0.001) and the morning after surgery (3.2 +/- 2.6 vs 5.0 +/- 2.2, P < 0.05), but otherwise pain scores were not significantly different. There were no differences in opioid-related side effects over the course of the study. CONCLUSION: Perioperative oral gabapentin reduced the amount of morphine used for postoperative pain after spinal fusion surgery, but not overall opioid-related side effects. Initial pain scores were lower in the treatment group. Perioperative use of gabapentin seems to be an effective adjunct to improve pain control in the early stages of recovery in children and adolescents undergoing spinal fusion.

Parent/nurse-controlled analgesia for children with developmental delay.

BACKGROUND: Children with developmental delay are often unable to verbalize pain or advocate for themselves owing to cognitive, motor, or verbal limitations, which puts them at increased risk for poor pain assessment and management. Although patient-controlled analgesia has been shown to be safe, effective, and superior to intermittent opioid dosing, not all children can operate patient-controlled analgesia independently. Parent/nurse-controlled analgesia (PNCA) may be an option for these children. However, the safety and efficacy of PNCA have not been thoroughly evaluated and many practitioners are reluctant to use it. OBJECTIVES: The purpose of this study was to evaluate the outcomes associated with PNCA in pediatric patients with identified developmental delay. METHODS: A retrospective review of treatment with PNCA was conducted from a convenience sample of charts for 71 children with developmental delay. Data were collected for 72 hours or until the PNCA was discontinued, whichever came first. RESULTS: Mean pain scores were low, as was the amount of opioid required to keep patients comfortable. Side effects, with the exception of oxygen therapy, were similar to previous studies regarding PNCA. Somnolence and respiratory depression leading to the administration of naloxone occurred in 2.8% of patients, and potential causes were identified. DISCUSSION: Pain scores, side effects, and adverse events suggest that PNCA may be an effective method of pain control for children with developmental delay. Diligent monitoring and education are crucial to ensure safety.

Advanced practice nurse-directed telephone management of acute pain following pediatric spinal fusion surgery.

PURPOSE: Children undergoing spinal fusion surgery require sophisticated pain management. This study describes an integrated system of pain management primarily directed by an advanced practice nurse (APN), encompassing both the inpatient and outpatient settings. DESIGN AND METHODS: A retrospective chart review was conducted. Pain management and patient education began in the hospital. The APN provided telephone-based follow-up and management after discharge. RESULTS: An average of four phone calls over 9 days was required per patient. No complications were reported. PRACTICE IMPLICATIONS: Results of this study support the APN telephone management of postoperative pain once children are discharged following extensive surgery.

A prospective evaluation of opioid weaning in opioid-dependent pediatric critical care patients.

Critically ill children are treated with opioid medication in an attempt to decrease stress and alleviate pain during prolonged pediatric intensive care. This treatment plan places children at risk for opioid dependency. Once dependent, children need to be weaned or risk development of a withdrawal syndrome on abrupt cessation of medication. We enrolled opioid-dependent children into a prospective, randomized trial of 5- versus 10-day opioid weaning using oral methadone. Children exposed to opioids for an average of 3 wk showed no difference in the number of agitation events requiring opioid rescue (3 consecutive neonatal abstinence scores >8 every 2 h) in either wean group. Most of the events requiring rescue occurred on day 5 and 6 of the wean in both treatment groups. Patients may be able to be weaned successfully in 5 days once converted to oral methadone, with a follow-up period after medication wean to observe for a delayed withdrawal syndrome.

Controlled-release oxycodone for the management of pediatric postoperative pain.

Studies addressing pain management after pediatric spinal fusion surgery have focused on the use of patient-controlled or epidural analgesia during the immediate postoperative period. Controlled-release (CR) analgesics have been found to be safe and effective in adults. The purpose of this study was to describe the use of oxycodone-CR in pediatric patients after the immediate postoperative period. A retrospective chart review of 62 postoperative spinal fusion patients (10-19 years) was conducted. The mean initial oxycodone-CR dose was 1.24 mg/kg/day. The mean ratio of conversion from parenteral morphine equivalents to oxycodone-CR was 1:1. Mean pain scores decreased from 4.2/10 to 3.7/10 with the transition to oxycodone-CR. Common side effects included dizziness, constipation, and nausea. Oxycodone-CR was used for an average of 13.3 days, which included an average wean time of 6 days. Results of this study demonstrate safe and effective use of oxycodone-CR in the pediatric spinal fusion population.
