Performing US-guided nerve blocks in the postanesthesia care unit (PACU) for upper extremity fractures: is this feasible in children?

Bothell, WA, USA) with a 20G spinal needle using the subcostal oblique approach described by Hebbard. 2.5 ml of 2.5% levobupivacaine was injected under ultrasound guidance (Figures 1 and 2). The patient remained hemodynamically stable throughout the procedure, with no increase in heart rate or blood pressure at the time of incision. No analgesics were administered intraoperatively. Postoperatively, regular pain assessment was made using the Neonatal Infant Pain Scale (NIPS). In the subsequent 24 h, the patient received two doses of both codeine (2 mg) and paracetamol (30 mg). The NIPS remained zero throughout. We agree with Fredrickson that ultrasound-guided TAP block is a feasible analgesic option in neonatal surgery. The technique holds promise as an alternative to traditional analgesic techniques in selected neonates presenting for abdominal surgery, such as this case of reversal of ileostomy.

Health Care Utilization and Costs Associated With Pediatric Chronic Pain

The population prevalence of pediatric chronic pain is not well characterized, in part because of a lack of nationally representative data. Previous research suggests that pediatric chronic pain prolongs inpatient stay and increases costs, but the population-level association between pediatric chronic pain and health care utilization is unclear. We use the 2016 National Survey of Childrens Health to describe the prevalence of pediatric chronic pain, and compare health care utilization among children ages 0 to 17 years according to the presence of chronic pain. Using a sample of 43,712 children, we estimate the population prevalence of chronic pain to be 6%. In multivariable analysis, chronic pain was not associated with increased odds of primary care or mental health care use, but was associated with greater odds of using other specialty care (odds ratio [OR]u2009=u20092.01, 95% confidence interval [CI] = 1.62-2.47; Pu2009<u2009.001), complementary and alternative medicine (ORu2009=u20092.32, 95% CI = 1.79-3.03; Pu2009<u2009.001), and emergency care (ORu2009=u20091.62, 95% CI = 1.29-2.02; Pu2009<u2009.001). In this population-based survey, children with chronic pain were more likely to use specialty care but not mental health care. The higher likelihood of emergency care use in this group raises the question of whether better management of pediatric chronic pain could reduce emergency department use.nnnPERSPECTIVEnAmong children with chronic pain, we show high rates of use of emergency care but limited use of mental health care, which may suggest opportunities to increase multidisciplinary treatment of chronic pain.

Pectoralis blocks for insertion of an implantable cardioverter defibrillator in two patients with Duchenne muscular dystrophy

Patients with Duchenne muscular dystrophy (DMD) often have systemic manifestations with comorbid involvement of the cardiac and respiratory systems that increase the risk of anesthetic and perioperative morbidity. These patients frequently develop progressive myocardial involvement with cardiomyopathy, depressed cardiac function, and arrhythmias. The latter may necessitate the placement of an automatic implantable cardioverter defibrillator (AICD) insertion. As a means of avoiding the need for general anesthesia and its inherent potential of morbidity, regional anesthesia may be used in specific cases. We present two cases of successful AICD insertion in patients with DMD using unilateral pectoralis and intercostal nerve blocks supplemented with intravenous sedation. Relevant anatomy for this regional anesthetic technique is reviewed and benefits of this anesthetic technique compared to general anesthesia are discussed.

Pediatric chronic pain and caregiver burden in a national survey

Abstract Background and aims Caring for children with chronic pain incurs burdens of cost and time for families. We aimed to describe variation in caregiver burden among parents of adolescents with chronic pain who responded to a nationally-representative survey. Our secondary aim was to identify child and parent characteristics associated with increased caregiver burden. Methods We used de-identified, publicly-available data from the 2016 National Survey of Children’s Health (NSCH), designed to be representative of non-institutionalized children in the United States. We analyzed data for households where an adolescent age 12–17 years old was reported by a parent to have chronic pain. Outcomes included the parent’s time spent on the child’s health needs, reduced labor force participation, and out-of-pocket medical costs. Results Data on 1,711 adolescents were analyzed. For adolescents with chronic pain, 15% of parents reported spending at least 1 h/week on their child’s health care, 14% reported cutting back on paid work, and 36% reported spending ≥

Spinal anesthesia instead of general anesthesia for infants undergoing tendon Achilles lengthening

500 on their child’s health care in the past 12 months. Adolescents’ general health status and extent of specialized health care needs predicted increased caregiver burden across the three measures. Conversely, no consistent differences in caregiver burden were noted according to demographic or socioeconomic characteristics. Conclusions Among adolescents with chronic pain identified on a nationally-representative survey, parents frequently reported reducing work participation and incurring out-of-pocket expenses in providing health care for their child. Caregiver burdens increased with indicators of greater medical complexity (e.g. presence of comorbidities, need for specialized health care) and poorer overall adolescent health status. Implications We add a national-level perspective to studies previously performed in clinical samples addressing caregiver burden in pediatric chronic pain. Initiatives to reduce the burden of caring for children with chronic pain, described in prior work, may be especially beneficial for families with adolescents whose chronic pain is accompanied by other health problems or requires coordination of care among multiple providers.

Optimizing the securement of epidural catheters: an in vitro trial

Spinal anesthesia (SA) has been used relatively sparingly in the pediatric population, as it is typically reserved for patients in whom the perceived risk of general anesthesia is high due to comorbid conditions. Recently, concern has been expressed regarding the potential long-term neurocognitive effects of general anesthesia during the early stages of life. In view of this, our center has developed a program in which SA may be used as the sole agent for applicable surgical procedures. While this approach in children is commonly used for urologic or abdominal surgical procedures, there have been a limited number of reports of its use for orthopedic procedures in this population. We present the use of SA for 6 infants undergoing tendon Achilles lengthening, review the use of SA in orthopedic surgery, describe our protocols and dosing regimens, and discuss the potential adverse effects related to this technique.

Rapid fluid administration: an evaluation of two techniques

Introduction Epidural anesthesia is frequently used to provide postoperative analgesia following major surgical procedures. Secure fixation of the epidural catheter is necessary to prevent premature dislodgment and loss of epidural analgesia. Using an in vitro model, the current prospective study evaluates different types of dressings for securement of an epidural catheter by quantifying the force in Newtons (N) required for dislodgment using a digital force gage. Methods Four methods of epidural catheter securement were used on a simulator mannequin: 1) Suresite® Window Clear Dressing, 2) Op-Site Post-Op® Visible Dressing, 3) Steri-Strips® and Suresite Window Clear Dressing, and 4) Steri-Strips and Op-Site Post-Op Visible Dressing. Each method of securement was assessed 10 times to calculate the mean force required to dislodge the catheter. Mean force of dislodgment for each method was compared using parametric tests. Results The force (mean ± SD) required for catheter dislodgment for the four methods was 14.0±2.9, 2, 10.7±1.5, 8.6±2.3, and 9.6±2.2 N, respectively. The pairwise difference showed that the Suresite Window Clear Dressing was the best securement method when compared with other methods. Conclusion Our study demonstrates the advantage of the Suresite Window Clear Dressing in securing the epidural catheter. Future clinical trials are needed to validate these findings.

Caregivers’ knowledge and acceptance of complementary and alternative medicine in a tertiary care pediatric hospital

Objective Rapid administration of fluid remains a cornerstone in treatment of shock and when caring for trauma patients. A range of devices and technologies are available to hasten fluid administration time. While new devices may optimize fluid delivery times, impact on subjective experience compared to traditional methods is poorly documented. Our study evaluated administration time and provider experience using two unique methods for fluid administration. Materials and methods Prospective comparison of objective and subjective outcomes using a novel infusion device (LifeFlow® Rapid Infuser) and the traditional push–pull syringe method in a simulated model of rapid fluid infusion. Ten paired trials were conducted for each of three intravenous catheter gauges. Providers administered 500 mL of isotonic crystalloid through an intravenous catheter with both LifeFlow and a push–pull device. Administration time was compared between devices using paired t-tests. Participants’ subjective physical demand, effort, pain, and fatigue using each device were recorded using 21-point visual analog scales and compared between devices using sign-rank tests. Results Fluid administration time was significantly decreased with LifeFlow compared to the push–pull device with the 18-gauge catheter (2.5±0.8 vs 3.8±1.0 minutes; 95% CI of difference: 0.9, 1.8 minutes; P<0.001). Findings were similar for other catheter sizes. No improvements in subjective experience were noted with the LifeFlow device. Increased physical demand with the LifeFlow device was noted with 18 and 22 gauge catheters, and increased fatigue with the LifeFlow device was noted for all catheter sizes. Conclusion The LifeFlow device was faster than the push–pull syringe method in our simulated scenario. However, provider subjective experience was not improved with the LifeFlow device.

Double-Blind Randomized Placebo-Controlled Trial of Single-Dose Intravenous Acetaminophen for Pain Associated With Adenotonsillectomy in Pediatric Patients With Sleep-Disordered Breathing

Background The use of complementary and alternative medicine (CAM) therapies has increased in children, especially in those with chronic health conditions. However, this increase may not translate into acceptance of CAM in the perioperative setting. We surveyed caregivers of patients undergoing surgery to determine their knowledge and acceptance of hypnotherapy, acupuncture, and music therapy as alternatives to standard medication in the perioperative period. Materials and methods An anonymous, 12-question survey was administered to caregivers of children undergoing procedures under general anesthesia. Caregivers reported their knowledge about hypnotherapy, music therapy, and acupuncture and interest in one of these methods during the perioperative period. CAM acceptance was defined as interest in one or more CAM methods. Results Data from 164 caregivers were analyzed. The majority of caregivers were 20–40 years of age (68%) and mothers of the patient (82%). Caregivers were most familiar with acupuncture (70%), followed by music therapy (60%) and hypnotherapy (38%). Overall CAM acceptance was 51%. The acceptance of specific CAM modalities was highest for music therapy (50%), followed by hypnotherapy (17%) and acupuncture (13%). In multivariable logistic regression, familiarity with music therapy was associated with greater odds of CAM acceptance (odds ratio=3.36; 95% CI: 1.46, 7.74; P=0.004). Conclusion Overall CAM acceptance among caregivers of children undergoing surgery was 51%, with music therapy being the most accepted CAM method. Familiarity with music therapy was the only factor that was independently associated with accepting CAM in the perioperative period. The low acceptance for acupuncture and hypnosis in the perioperative situation may be related to insufficient parental knowledge and information.

Rapid Response Team activation for pediatric patients on the acute pain service

OBJECTIVESnAdequate pain control is an important component in the postoperative outcome for pediatric adenotonsillectomy patients with sleep-disordered breathing (SDB). Intravenous acetaminophen appears to be a favorable analgesic adjunct owing to its predictable pharmacokinetics and opioid-sparing effects; however, its role in pediatric adenotonsillectomy pain management remains unclear.nnnMETHODSnIn this prospective, randomized, double-blinded, controlled study, subjects with the diagnosis of SDB, aged 2 to 8 years, who required extended postoperative admission, received intravenous acetaminophen (15 mg/kg) or saline placebo intraoperatively in addition to morphine (0.1 mg/kg) for postoperative surgical analgesia. Pain scores in the postanesthesia care unit (PACU) using the FLACC (Faces, Leg, Activity, Cry, Consolability) score were used to determine the need for supplemental analgesic agents in the PACU. The PACU time and time to the first request for pain medication on the inpatient ward were also measured.nnnRESULTSnA total of 239 patients were included in the final data analysis (118 in the intravenous acetaminophen group and 121 in the saline placebo group). The 2 groups did not differ in the proportion of patients reaching FLACC scores = 4 in the PACU (p = 0.223); mean FLACC scores in the PACU (p = 0.336); mean PACU time (p = 0.883); or time to requesting pain medication on the inpatient ward (p = 0.640).nnnCONCLUSIONSnA single intraoperative dose of intravenous acetaminophen did not alter the postoperative course of pediatric patients with SDB following adenotonsillectomy.
