Diversity, equity, and inclusion within the Society for Pediatric Anesthesia: A mixed methods assessment. Paediatr Anaesth 2023; 33:435-445. [PMID: 36715575 DOI: 10.1111/pan.14642] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2022] [Revised: 01/05/2023] [Accepted: 01/24/2023] [Indexed: 01/31/2023]
Abstract
BACKGROUND Leadership of the Society for Pediatric Anesthesia created the Diversity, Equity, and Inclusion committee in 2018 to prioritize diversity work. The Society for Pediatric Anesthesia-Diversity, Equity, and Inclusion committee implemented a baseline survey of the Society for Pediatric Anesthesia membership in 2020 to assess demographics, equity in leadership, inclusivity, and attitudes toward diversity work. The Society for Pediatric Anesthesia plays a significant role in shaping the future of pediatric anesthesiology and in supporting our diverse pediatric patients. METHODS This study is an IRB-exempt, cross-sectional survey of the Society for Pediatric Anesthesia membership. Quantitative analysis provided descriptive statistics of demographics, practice characteristics, and involvement within the Society for Pediatric Anesthesia. Qualitative thematic analysis provided an in-depth assessment of perceptions of diversity, challenges faced, and prioritization of Diversity, Equity, and Inclusion efforts within the Society for Pediatric Anesthesia. RESULTS Out of 3 242 Society for Pediatric Anesthesia members, 1 232 completed the survey representing 38% of overall membership. Respondents were 89.2% United States members, 52.7% female, 55.7% non-Hispanic White, 88.6% heterosexual, 95.7% non-military, 59.2% religious, and 2.1% have an Americans with Disabilities Act recognized disability. All major United States geographical areas were represented equally with 71% practicing in urban areas and 67% in academic settings. Ethnic/racial minorities were more likely to be international medical graduates (p < .001). Among United States members, 41.5% report being fluent in a language other than English, and 23.5% of those fluent in another language are certified to interpret. Compared to men, women are less likely to be in leadership roles (p < .003), but we found no difference in participation and leadership when stratified by race/ethnicity, geography, international medical graduate status, or sexuality. Racial/ethnic minorities (p < .028), women (p < .001), and lesbian, gay, bisexual, transgender, and queer members (p < .044) more frequently hold lower academic rank positions when compared to white, heterosexual, and male members. Half of respondents were unsure whether diversity, equity, and inclusion challenges existed within the Society for Pediatric Anesthesia while the other half demonstrated opposing views. Among those who reported diversity, equity, and inclusion challenges, the themes centered around persistent marginalization, the need for more inclusive policies and increased psychological safety, and lack of leadership diversity. CONCLUSIONS Compared to the diversity of the pediatric population we serve, there are still significant gaps in demographic representation within the Society for Pediatric Anesthesia. As well, there is no consensus among Society for Pediatric Anesthesia membership regarding perceptions of diversity, equity, and inclusion in pediatric anesthesia in the United States. Among those who reported diversity challenges, opportunities for the Society for Pediatric Anesthesia and Anesthesiology Departments to better support minoritized members included bolstering workforce diversity efforts and awareness via more inclusive policies, improved psychological safety, and increasing diversity in leadership. If pediatric anesthesiology is like other specialties, gaining consensus and improving diversity in the workforce might advance pediatric anesthesia innovation, quality, and safety for children of all backgrounds in the United States.

Abstract
We report a measurement of the D^{0} and D^{+} lifetimes using D^{0}→K^{-}π^{+} and D^{+}→K^{-}π^{+}π^{+} decays reconstructed in e^{+}e^{-}→cc[over ¯] data recorded by the Belle II experiment at the SuperKEKB asymmetric-energy e^{+}e^{-} collider. The data, collected at center-of-mass energies at or near the ϒ(4S) resonance, correspond to an integrated luminosity of 72 fb^{-1}. The results, τ(D^{0})=410.5±1.1(stat)±0.8(syst) fs and τ(D^{+})=1030.4±4.7(stat)±3.1(syst) fs, are the most precise to date and are consistent with previous determinations.

Measurements of the Branching Fractions of the Semileptonic Decays Ξ_{c}^{0}→Ξ^{-}ℓ^{+}ν_{ℓ} and the Asymmetry Parameter of Ξ_{c}^{0}→Ξ^{-}π^{+}. PHYSICAL REVIEW LETTERS 2021; 127:121803.

Abstract
Using data samples of 89.5 and 711 fb^{-1} recorded at energies of sqrt[s]=10.52 and 10.58 GeV, respectively, with the Belle detector at the KEKB e^{+}e^{-} collider, we report measurements of branching fractions of semileptonic decays Ξ_{c}^{0}→Ξ^{-}ℓ^{+}ν_{ℓ} (ℓ=e or μ) and the CP-asymmetry parameter of Ξ_{c}^{0}→Ξ^{-}π^{+} decay. The branching fractions are measured to be B(Ξ_{c}^{0}→Ξ^{-}e^{+}ν_{e})=(1.31±0.04±0.07±0.38)% and B(Ξ_{c}^{0}→Ξ^{-}μ^{+}ν_{μ})=(1.27±0.06±0.10±0.37)%, and the decay parameter α_{Ξπ} is measured to be 0.63±0.03±0.01 with much improved precision compared with the current world average. The corresponding ratio B(Ξ_{c}^{0}→Ξ^{-}e^{+}ν_{e})/B(Ξ_{c}^{0}→Ξ^{-}μ^{+}ν_{μ}) is 1.03±0.05±0.07, which is consistent with the expectation of lepton flavor universality. The first measured asymmetry parameter A_{CP}=(α_{Ξ^{-}π^{+}}+α_{Ξ[over ¯]^{+}π^{-}})/(α_{Ξ^{-}π^{+}}-α_{Ξ[over ¯]^{+}π^{-}})=0.024±0.052±0.014 is found to be consistent with zero. The first and the second uncertainties above are statistical and systematic, respectively, while the third ones arise due to the uncertainty of the Ξ_{c}^{0}→Ξ^{-}π^{+} branching fraction.

Vaping and E-Cigarette Use in Children and Adolescents: Implications on Perioperative Care From the American Society of Anesthesiologists Committee on Pediatric Anesthesia, Society for Pediatric Anesthesia, and American Academy of Pediatrics Section on Anesthesiology and Pain Medicine.

Abstract
Electronic cigarettes (e-cigarettes) or vaping use in adolescents has emerged as a public health crisis that impacts the perioperative care of this vulnerable population. E-cigarettes have become the most commonly used tobacco products among youth in the United States. Fruit and mint flavors and additives such as marijuana have enticed children and adolescents. E-cigarette, or vaping, product use-associated lung injury (EVALI) is a newly identified lung disease linked to vaping. Clinical presentation of EVALI can be varied, but most commonly includes the respiratory system, gastrointestinal (GI) tract, and constitutional symptoms. Clinical management of EVALI has consisted of vaping cessation and supportive therapy, including supplemental oxygen, noninvasive ventilation, mechanical ventilation, glucocorticoids, and empiric antibiotics, until infectious causes are eliminated, and in the most severe cases, extracorporeal membrane oxygenation (ECMO). Currently, although there is an insufficient evidence to determine the safety and the efficacy of e-cigarettes for perioperative smoking cessation, EVALI clearly places these patients at an increased risk of perioperative morbidity. Given the relatively recent introduction of e-cigarettes, the long-term impact on adolescent health is unknown. As a result, the paucity of postoperative outcomes in this potentially vulnerable population does not support evidence-based recommendations for the management of these patients. Clinicians should identify "at-risk" individuals during preanesthetic evaluations and adjust the risk stratification accordingly. Our societies encourage continued education of the public and health care providers of the risks associated with vaping and nicotine use and encourage regular preoperative screening and postoperative outcome studies of patients with regard to smoking and vaping use.

Evidence for X(3872)→J/ψπ^{+}π^{-} Produced in Single-Tag Two-Photon Interactions. PHYSICAL REVIEW LETTERS 2021; 126:122001.

Abstract
We report the first evidence for X(3872) production in two-photon interactions by tagging either the electron or the positron in the final state, exploring the highly virtual photon region. The search is performed in e^{+}e^{-}→e^{+}e^{-}J/ψπ^{+}π^{-}, using 825 fb^{-1} of data collected by the Belle detector operated at the KEKB e^{+}e^{-} collider. We observe three X(3872) candidates, where the expected background is 0.11±0.10 events, with a significance of 3.2σ. We obtain an estimated value for Γ[over ˜]_{γγ}B(X(3872)→J/ψπ^{+}π^{-}) assuming the Q^{2} dependence predicted by a cc[over ¯] meson model, where -Q^{2} is the invariant mass squared of the virtual photon. No X(3915)→J/ψπ^{+}π^{-} candidates are found.

Off-label use of dexmedetomidine in paediatric anaesthesiology: an international survey of 791 (paediatric) anaesthesiologists. Eur J Clin Pharmacol 2020; 77:625-635. [PMID: 33119787 PMCID: PMC7935836 DOI: 10.1007/s00228-020-03028-2] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Accepted: 10/15/2020] [Indexed: 01/02/2023]
Abstract
Purpose The purpose of this international study was to investigate prescribing practices of dexmedetomidine by paediatric anaesthesiologists. Methods We performed an online survey on the prescription rate of dexmedetomidine, route of administration and dosage, adverse drug reactions, education on the drug and overall experience. Members of specialist paediatric anaesthesia societies of Europe (ESPA), New Zealand and Australia (SPANZA), Great Britain and Ireland (APAGBI) and the USA (SPA) were consulted. Responses were collected in July and August 2019. Results Data from 791 responders (17% of 5171 invitees) were included in the analyses. Dexmedetomidine was prescribed by 70% of the respondents (ESPA 53%; SPANZA 69%; APAGBI 34% and SPA 96%), mostly for procedural sedation (68%), premedication (46%) and/or ICU sedation (46%). Seventy-three percent had access to local or national protocols, although lack of education was the main reason cited by 26% of the respondents not to prescribe dexmedetomidine. The main difference in dexmedetomidine use concerned the age of patients (SPA primarily < 1 year, others primarily > 1 year). The dosage varied widely ranging from 0.2–5 μg kg−1 for nasal premedication, 0.2–8 μg kg−1 for nasal procedural sedation and 0–4 μg kg−1 intravenously as adjuvant for anaesthesia. Only ESPA members (61%) had noted an adverse drug reaction, namely bradycardia. Conclusion The majority of anaesthesiologists use dexmedetomidine in paediatrics for premedication, procedural sedation, ICU sedation and anaesthesia, despite the off-label use and sparse evidence. The large intercontinental differences in prescribing dexmedetomidine call for consensus and worldwide education on the optimal use in paediatric practice.

Abstract
BACKGROUND Myringotomy tube placement is a pediatric procedure frequently performed under inhalational anesthesia without intravenous line placement. Emergence delirium is common following sevoflurane anesthesia, and can lead to patient harm and escalation of nursing care. Our goal was to determine if intraoperative acupuncture, compared to standard of care, reduces emergence delirium in children undergoing myringotomy tube placement. METHODS Single center, randomized, controlled trial at a university hospital, including children ages 1-6 years with ASA physical status 1-3 scheduled for myringotomy tube placement. Participants were stratified based on midazolam premedication and randomized to intraoperative acupuncture (AC, N.=49) or standard anesthesia care (SC, N.=50). Acupuncture needles were placed in bilateral Heart 7 (HT7) and ear Shen Men points after anesthesia induction. A blinded observer in the PACU assessed emergence delirium using the Pediatric Anesthesia Emergence Delirium (PAED) scale. Endpoints were highest PAED score in the recovery room and post-discharge agitation and sleep quality. RESULTS Patient baseline characteristics were similar between treatment groups. With midazolam premedication, the highest PAED score was 11.6 in patients receiving AC and 12.0 for SC. Without midazolam premedication, the highest PAED was 11.8 in patients receiving AC and 10.7 for SC. The overall PAED score difference between AC and SC groups was 0.33 (95% CI -1.5, 2.2, P=0.723). CONCLUSIONS Intraoperative acupuncture at HT7 and ear Shen Men did not reduce PAED scores after myringotomy tube placement. Based on these data, it is therefore unlikely that a larger study of the same design would demonstrate a significant effect of intraoperative acupuncture on emergence delirium after brief sevoflurane anesthesia. However, other acupuncture points or techniques could be considered.

Isotensor Dibaryon in the pp→ppπ^{+}π^{-} Reaction? PHYSICAL REVIEW LETTERS 2018; 121:052001.

Abstract
Exclusive measurements of the quasifree pp→ppπ^{+}π^{-} reaction have been carried out at WASA@COSY by means of pd collisions at T_{p}=1.2 GeV. Total and differential cross sections have been extracted covering the energy region T_{p}=1.08-1.36 GeV, which is the region of N^{*}(1440) and Δ(1232)Δ(1232) resonance excitations. Calculations describing these excitations by t-channel meson exchange are at variance with the measured differential cross sections and underpredict substantially the experimental total cross section. An isotensor ΔN dibaryon resonance with I(J^{P})=2(1^{+}) produced associatedly with a pion is able to overcome these deficiencies.

Abstract
Taking advantage of the high acceptance and axial symmetry of the WASA-at-COSY detector, and the high polarization degree of the proton beam of COSY, the reaction p[over →]p→ppη has been measured close to threshold to explore the analyzing power A_{y}. The angular distribution of A_{y} is determined with the precision improved by more than 1 order of magnitude with respect to previous results, allowing a first accurate comparison with theoretical predictions. The determined analyzing power is consistent with zero for an excess energy of Q=15 MeV, signaling s-wave production with no evidence for higher partial waves. At Q=72 MeV the data reveal strong interference of Ps and Pp partial waves and cancellation of (Pp)^{2} and Ss^{*}Sd contributions. These results rule out the presently available theoretical predictions for the production mechanism of the η meson.

Abstract
BACKGROUND We compared respiratory complications (RCs) in children who received intramuscular (IM) versus intravenous (IV) or no ketamine for intraocular pressure (IOP) measurement to test our observation that IM ketamine is associated with higher incidence of RCs. MATERIALS AND METHODS We analyzed 149 eye examinations under anesthesia with ketamine in 27 patients and 263 non-ketamine examinations under anesthesia in 81 patients using a mixed effects logistic regression model. RESULTS IM KETAMINE WAS STRONGLY ASSOCIATED WITH INCREASED ODDS OF RCS COMPARED TO NO KETAMINE (ODDS RATIO (OR): 20.23, P < 0.0001) and to IV ketamine (OR: 6.78, P = 0.02), as were higher American Society of Anesthesiologists (ASA) classification (OR: 2.60, P = 0.04), and the use of volatile agents (OR: 3.32, P = 0.02). CONCLUSION Further studies should be conducted to confirm our observation of increased RCs with IM ketamine.

The laryngeal mask airway for pediatric adenotonsillectomy: predictors of failure and complications. Int J Pediatr Otorhinolaryngol 2013; 77:25-8.

Abstract
OBJECTIVES We hypothesize that the laryngeal mask airway (LMA) is a safe technique for airway management in pediatric adenotonsillectomy (T&A). METHODS After institutional review board (I.R.B.) approval, we conducted a retrospective review of 1199 medical records of children who underwent T&A from 2002 to 2006 at Doernbecher Children's Hospital, a teaching institution in Portland, OR. There were no significant demographic differences between the LMA (n=451), endotracheal tube (ETT) (n=715), and failed LMA groups (n=33). Outcome variables were LMA failure (LMA replaced with endotracheal tube), and any complication. We collected demographic and medical data to determine the incidence and predictors of LMA failure, and to characterize the failed LMA group. RESULTS The incidence of LMA failure was 6.8%. Patients who underwent adenoidectomy had significantly lower odds of LMA failure compared to patients who had a tonsillectomy or adenotonsillectomy (OR 0.28, 95% CI 0.15-0.52, P<0.0001). One of the surgeons (OR 0.46, 95% CI 0.45-0.48, P<0.0001) was also associated with decreased odds of LMA failure. Controlled ventilation (OR 7.17, 95% CI 4.99-10.32, P<0.0001), and younger patients (OR 1.05 for each year decrease in age, 95% CI 1.03-1.07, P ≤ 0.0001) were associated with increased odds of LMA failure. The complication rate was 14.2% in the LMA group and 7.7% in the ETT group. Increased odds of developing any complication were seen in male patients (OR 1.4, 95% CI 1.01-1.7, P=0.04), and in patients with co-morbidities other than obstructive sleep apnea syndrome or upper respiratory tract infection (OR 4.2, 95% CI 1.03-17.2, P=0.04). The odds of developing a complication were lower in the ETT group compared to the LMA group (0.63, 0.46, 0.8, P=0.005). CONCLUSIONS LMA use for pediatric T&A is associated with a higher incidence of complications, mainly as a result of airway obstruction following insertion of the LMA or McIvor gag placement. Complications were more likely if tonsillectomy was performed when compared to adenoidectomy alone. Appropriate patient selection, careful insertion, and avoidance of controlled ventilation may decrease the incidence of LMA failure, especially if tonsillectomy is performed. The ability of surgeons to work around the LMA can modify the failure rate significantly.

Abstract
Background: Propofol and pentobarbital are commonly used to sedate children undergoing magnetic resonance imaging (MRI). Aim/Objective: To compare the safety of three types of sedation: intravenous propofol (PROP), mixed pentobarbital/propofol (PENT), and mixed pentobarbital group requiring supplemental sedation (PENT SUPP) regimens in pediatric patients following deep sedation (DS) for noncardiac MRI. Materials and Methods: We conducted a case-control study matching 619 cases with complications with 619 controls using data from our institution's sedation database for children deeply sedated for noncardiac MRI. Cases were defined as patients with any complication and we characterized complications from cases, and used a conditional logistic regression model to assess the association between three DS methods and occurrence of complications after adjusting for confounding variables. Results: We found that complications occurred in association with 794 (10.1%) of the 7,839 DSs performed for MRI between 1998 and 2008. Of the 794 cases, 619 cases met inclusion criteria for the study. Among the 619 cases that met inclusion criteria, 24 (0.3% of 7,839 DSs total) were associated with major complications. Type of sedation was significantly associated with the occurrence of complications, and the PENT group was associated with decreased odds of complications when compared to the PROP regimen (OR 0.68; 95% CI 0.46, 0.98; P=0.040) and compared to the PENT SUPP group (OR 0.60; 95% CI 0.31, 0.89; P<0.0001). Conclusions: DS with a pentobarbital technique was associated with decreased odds for complications when compared to a propofol-based technique or a pentobarbital technique requiring supplemental sedation.

Abstract
We report on an exclusive and kinematically complete high-statistics measurement of the basic double-pionic fusion reaction pn→dπ(0)π(0) over the full energy region of the ABC effect, a pronounced low-mass enhancement in the ππ-invariant mass spectrum. The measurements, which cover also the transition region to the conventional t-channel ΔΔ process, were performed with the upgraded WASA detector setup at COSY. The data reveal the Abashian-Booth-Crowe effect to be uniquely correlated with a Lorentzian energy dependence in the integral cross section. The observables are consistent with a narrow resonance with m=2.37 GeV, Γ≈70 MeV and I(J(P))=0(3(+)) in both pn and ΔΔ systems. Necessary further tests of the resonance interpretation are discussed.

Abstract
OBJECTIVES Analyze pediatric ERG data for adverse events, interventions, and outcomes of propofol sedations performed in near-complete darkness. AIM To demonstrate that deep sedation with propofol for ERG can be performed efficiently and safely in children in near-total darkness. BACKGROUND Full-field electroretinography (ERG) is a valuable tool for the diagnosis of vision loss in children. The ERG measures the electrical activity of the retina. In children, ERG quality significantly improves with deep sedation by allowing easier eye electrode placement and decreasing motion artifacts. As this procedure must be performed in darkness, administering sedation imposes unique challenges. METHODS AND MATERIALS ERGs are performed outside of the operating room in our hospital's electrophysiology suite. IVs are placed, and patients are allowed to adapt to complete darkness. An anesthesiologist then administers propofol sedation in the dark with the aid of a red-filter light source and monitor light shields. Data were collected on 379 patients (411 ERGs) performed from 1996 to 2008. These records were reviewed and analyzed for demographic, medical, and anesthetic data. RESULTS Propofol sedation resulted in an ERG completion rate of 99.5%. During sedation, 8.5% (35) of patients experienced minor respiratory complications such as airway obstruction that resulted in an oxygen saturation <90%. A total of 9.7% (40) of patients required minor airway interventions such as a chin lift. CONCLUSIONS We demonstrated that pediatric sedation is a safe, efficient, and a cost-effective method for measuring ERGs in a challenging environment. The incidence of minor complications is low and appears similar to other studies of propofol sedation.

Factors affecting parental satisfaction following pediatric procedural sedation. J Clin Anesth 2010; 22:29-34. [PMID: 20206848 DOI: 10.1016/j.jclinane.2009.02.012] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2008] [Revised: 02/04/2009] [Accepted: 02/23/2009] [Indexed: 12/24/2022]
Abstract
STUDY OBJECTIVE To investigate factors affecting parental satisfaction with a pediatric sedation service in a university hospital setting. DESIGN Prospective, observational study with interviews using a survey instrument. SETTING Academic university hospital. SUBJECTS Parents (or legal guardians; hereafter "parents") of 220 children scheduled for sedation with the hospital's pediatric sedation service. INTERVENTIONS AND MEASUREMENTS Caregivers of children scheduled for sedation were interviewed using a validated survey instrument. The instrument was designed to investigate the quality of communication, environment, care provided, and the overall experience. We followed patients by telephone the day after discharge. Chi-square or linear-by-linear association tests were used to evaluate associations between satisfaction scores and demographic variables; the Mann-Whitney test was used for mean levels of satisfaction in anxious versus non-anxious children. MAIN RESULTS Of 222 parents approached, 220 agreed to participate (response rate = 99.1%). Significant associations between each area of satisfaction and parents' overall satisfaction existed (P < 0.001). Previous sedations, types of sedation, age of child, or any individual provider were not significantly associated with overall satisfaction. Caregivers of anxious children reported less satisfaction than caregivers of non-anxious children. Parents of children who underwent magnetic resonance imaging reported the lowest mean satisfaction scores. CONCLUSIONS Overall satisfaction was high, and care provided by anesthesiologists was significantly associated with overall satisfaction. A site in our institution was associated with significantly lower satisfaction as a result of inadequate space and privacy.

Abstract
OBJECT In this study, the authors evaluated the efficacy and safety of modified orbitozygomatic craniotomy for resection of craniopharyngioma in children. METHODS A prospective, institutional review board-approved database was retrospectively reviewed for pediatric patients undergoing craniopharyngioma resection performed by a single surgeon. RESULTS Ten patients underwent craniopharyngioma resection surgery between July 2000 and January 2006 (4 girls and 6 boys, ages 1.5-17 years). Nine patients presented to the authors' institution, and 1 patient was referred after surgery and radiation therapy were administered elsewhere. Nine patients presented with visual field deficits (2 with unilateral or bilateral light perception only) and 5 with endocrine dysfunction. Eight patients had large tumors that significantly displaced the optic chiasm and hypothalamus. All patients underwent a modified frontotemporal orbitozygomatic osteotomy in a single piece. The lamina terminalis was opened in 4 patients with third ventricular extension. One patient required a staged transsphenoidal operation to remove residual tumor in the sella turcica, and 1 patient underwent a contralateral subtemporal approach to resect a daughter lesion in the prepontine cistern. Complete radiographic resection was achieved in all patients. Follow-up averaged 55 months (range 12-95 months). Vision was improved in 8 patients and remained stable in 2. All patients had postoperative endocrine dysfunction. One patient experienced transient cranial nerve IV palsy and 1 suffered a small caudate stroke 5 months after surgery without sequelae. Two patients experienced polyphagia and weight gain without other symptoms of hypothalamic dysfunction. There were no other new neurological deficits. CONCLUSIONS Modified orbitozygomatic craniotomy provides excellent exposure of the suprasellar region with minimal brain retraction, allowing complete resection of craniopharyngiomas with good visual and neurological results.

Office-based dental rehabilitation in children with special healthcare needs using a pediatric sedation service model. J Oral Maxillofac Surg 2007; 65:427-33. [PMID: 17307588 DOI: 10.1016/j.joms.2005.12.057] [Citation(s) in RCA: 22] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2005] [Revised: 08/09/2005] [Accepted: 12/06/2005] [Indexed: 11/21/2022]
Abstract
PURPOSE 1) To review our experience with office-based sedation/anesthesia for children with special healthcare needs who underwent dental rehabilitation at our institution. 2) To compare the cost to comparable patients who underwent similar procedures in the operating room. PATIENTS AND METHODS Retrospective review of patients' medical records and the sedation service database. Group CL: 114 patients who underwent office-based dental rehabilitation (135 procedures). Group OR: 23 patients who underwent dental rehabilitation under general anesthesia in the operating room for cost comparison. OUTCOMES 1) EFFICACY (procedure completion rate and unplanned admissions); 2) SAFETY (complications and interventions); 3) Comparison of mean hospital charges billed between groups. RESULTS Demographics were similar in both groups. The most common specific underlying diagnoses were autism (38%), cerebral palsy/developmental delay (18%) and ADHD (4%) in both groups. EFFICACY procedure completion rate was 98.5% (2 aborted). There was 1 (0.7%) unplanned postanesthetic care unit admission due to an adverse drug event. SAFETY 2 (1.5%) patients required invasive airway control. Eighteen (13.3%) patients developed transient hypoxemia. Twenty-three (17%) patients had airway obstruction needing simple intervention, and 1 (0.7%) patient had hypotension. There were no serious complications. Cost: mean total hospital charges were considerably higher in group OR ($6,126), versus group CL ($1,277), even after adjustment for inflation and length of procedure (P<.0001). CONCLUSION Office-based dental rehabilitation using a pediatric sedation service model in children with special needs is efficient, and can achieve average savings of $4,849 in hospital charges per patient.

Abstract
PURPOSE OF REVIEW Nonoperating-room anesthesia includes sedation or anesthesia for radiological imaging, cardiac catheterization, office-based surgery, and pediatric procedures or investigations, all of which have seen explosive growth over the last decade. This review discusses the factors that are driving this growth and the challenges we face as a profession to accommodate new practice paradigms. RECENT FINDINGS Many departments have difficulty providing services for nonoperating-room anesthesia. A shortage of providers, insufficient reimbursement, and lack of institutional support have been identified as barriers limiting delivery of pediatric nonoperating-room sedation services. Practitioners from other specialties appear increasingly eager to provide sedation at an institutional level. The use of propofol by nonanesthesiologists is widespread, and the issue of provider credentialing has yet to be fully resolved. The shift to nonoperating-room locations will continue, driven by cost savings and convenience for patients and providers. SUMMARY Nonoperating-room anesthesia will play a central role in anesthesia practice in the future. Provision of these services requires planning, personnel, and institutional resources. This should be a high priority for anesthesiology departments to ensure delivery of the highest quality of patient care in a cost-effective and organized manner.

Use of oxcarbazepine to treat a pediatric patient with resistant complex regional pain syndrome. THE JOURNAL OF PAIN 2006; 6:704-6. [PMID: 16202964 DOI: 10.1016/j.jpain.2005.05.005] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/17/2005] [Revised: 05/20/2005] [Accepted: 05/24/2005] [Indexed: 10/25/2022]
Abstract
UNLABELLED We describe a 12-year-old patient with severe, protracted complex regional pain syndrome type I. His pain did not respond to gabapentin, amitriptyline, physical therapy, opioids, or nonsteroidal drugs. Sympathetic or regional block was not attempted because of persistent bacteremia and severe local sepsis. His pain responded dramatically to the addition of oxcarbazepine, with rapid improvement in his symptoms and functional status. We suggest that oxcarbazepine might be a useful adjunct in the treatment of gabapentin-resistant complex regional pain syndrome type I in children and should be considered. PERSPECTIVE Oxcarbazepine's antinociceptive effect is mediated via sodium channel inhibition in neuropathic models and by inhibition of substance P and prostaglandins in anti-inflammatory models. The efficacy of oxcarbazepine in this patient might be attributable to these mechanisms or possibly to synergism with either gabapentin or the anti-inflammatory effects produced by amitriptyline.

Abstract
We describe a healthy neonate with abdominal distention, inadequate ventilation, and delayed extubation during anesthesia for minor surgery. Following rectal decompression and successful extubation, extreme abdominal distention recurred postoperatively after ingestion of clear fluids. We elicited a history of frequent and excessive flatus from the parents, and abdominal radiography revealed distended loops of small bowel with small lung volumes suggestive of aerophagia. The differential diagnosis of aerophagia is reviewed, the anesthetic implications discussed, and relevant literature pertaining to this condition summarized.

Abstract
BACKGROUND Information about the existence and organization of pediatric sedation services in North America is not available. We conducted a survey to collect this information from anesthesiologists at pediatric institutions and to identify factors perceived as limiting the development of sedation services. METHOD We electronically mailed a confidential survey about pediatric sedation practice to an attending anesthesiologist involved in pediatric sedation at 116 children's hospitals in the United States and Canada. We identified the institutions using Internet resources. Electronic mailing addresses were obtained from departmental websites, society membership directories and departmental administrators. Our follow-up for nonresponders was by a second e-mail and a telephone call. RESULTS A total of 54 completed questionnaires were received, a response rate of 47%. Forty-nine (91%) were received from US hospitals, and the remainder from Canadian. Fifty percent of hospitals had a formal pediatric sedation service. Fifty-four percent utilized a 'mobile' provider model. Hospital credentialing for nonanesthesiologist providers varied between 66 and 76% for 'deep' and 'conscious' sedation, respectively. A nurse-physician provider combination was the most common, utilized in 59% of hospitals. Anesthesiologists were the sole sedation providers in 26% of institutions. Propofol was used regularly by nonanesthesiologists for sedation of nonintubated (42%) and intubated (63%) patients. Eighty-seven percent of institutions reported barriers to development of pediatric sedation services. The most common barrier was a shortage of providers, particularly anesthesiologists. CONCLUSIONS Propofol use by nonanesthesiologists is common. Addressing the shortage of providers, and allocating resources for credentialing providers will encourage further development of pediatric sedation practice.

Abstract
OBJECTIVE To compare efficacy, safety, and hospital charges for common pediatric otolaryngology procedures with the use of intravenous sedation (IVS) vs general anesthesia (GA). DESIGN Retrospective chart study. SETTING Hospital-based pediatric otolaryngology practice. PATIENTS Patients younger than 18 years who underwent tympanostomy tube removal and/or patch myringoplasty with absorbable gelatin sponge, nasal ciliary biopsy, fine-needle aspiration, or other minor procedures between September 1, 1998, and August 31, 2001. INTERVENTIONS Procedures performed in 2 settings: outpatient clinic with IVS or operating room with GA. MAIN OUTCOME MEASURES Procedure completion rate, tympanic membrane perforation rate after ear procedures, complications, and hospital charges. RESULTS Of 103 procedures, 54 were performed with IVS and 49 with GA. Within the GA group, 32 of 49 patients had additional operations performed and were excluded from analysis of safety and hospital charges. Procedure completion rate was 100% in both groups. The most common procedure was tympanostomy tube removal with patch myringoplasty (IVS, 52 ears; GA, 42 ears). The rate of persistent tympanic membrane perforation was similar between these groups (IVS, 7 [16%] of 45 ears; GA, 5 [15%] of 33; P =.96). All complications were minor and occurred at similar rates (IVS, 10 [19%] of 54 ears; GA, 3 [18%] of 17; P =.94). These events included hypoxia, airway obstruction, and bradycardia, all of which resolved spontaneously or responded to noninvasive interventions such as oxygen or repositioning. Average hospital charges were significantly higher for the GA group (IVS, $356.22; GA, $1516.55; P<.001). CONCLUSION Various procedures can be performed safely, effectively, and with decreased hospital charges with the use of IVS administered by a pediatric sedation service.

Abstract
We present a case report of an asymptomatic 12-year-old girl who was incidentally noted to have a collapsed upper lobe of her right lung during anaesthesia for angiography. After initial success at reexpansion using manual ventilation and suctioning, the lobe collapsed again some 15 min later. Physiological parameters remained stable throughout. Consent was obtained for fibreoptic bronchoscopy which was performed uneventfully and resulted in reexpansion of the lobe. We discuss the difficulty in identifying patients at risk of this complication, the need for therapeutic intervention and the issue of consent.
