Abstract
Pain is frequently encountered in dermatology practice, which impairs the activities of daily living, adds to psychological morbidity, and therefore compromises the quality of life. It ranges from mild to severe in intensity across various dermatoses and requires prompt addressal and treatment. Diseases such as extensive pemphigus vulgaris and Stevens-Johnson syndrome are especially painful and require a multidisciplinary approach with the involvement of a pain specialist in their management. The main pathogenic types of pain include visceral nociceptive, somatic nociceptive, and neuropathic types, the latter two being most relevant in dermatological disorders. Somatic nociceptive pain is often seen in patients of Stevens-Johnson syndrome/ Toxic epidermal necrolysis, epidermolysis bullosa, pemphigus vulgaris, erythema nodosum, and hidradenitis suppurativa, while neuropathic pain is part of the disease process in dermatoses like leprosy, herpes zoster, and dysesthesia syndromes. Therapeutic approaches to pain management include the use of non-opioids (acetaminophen, non-steroidal anti-inflammatory agents), opioids, and non-pharmacological therapies, along with appropriate management of the underlying dermatosis. World Health Organisation (WHO) analgesic ladder remains the most commonly employed guideline for the management of pain, although treatment needs individualisation depending on the nature and severity of pain (acute/chronic), type of dermatosis, and patient factors. There is a paucity of literature pertaining to pain management in dermatology and this topic is often neglected due to a lack of awareness and knowledge of the topic. The present review aims to discuss the pain pathway, various painful conditions in the setting of medical dermatology practice, and their management along with relevant pharmacology of the commonly used analgesics.

Abstract
Children with cancer often require sedation before undergoing invasive procedures. Fentanyl, ketamine, and midazolam are effective drugs widely used for procedural sedation. This study aimed to investigate the efficacy and safety of midazolam-fentanyl (M-F) compared with midazolam-ketamine (M-K) for bedside procedural sedation among pediatric oncology patients. A randomized, double-blinded, crossover trial was conducted among children with cancer requiring procedural sedation for invasive procedures. Patients were randomly assigned either intravenous M-F or M-K and subsequently received the alternate regimens following the crossover design of the study. The efficacy and safety of the sedations including sedation time intervals, nausea score, vomiting episodes, pain score, adverse effects, and parent's satisfaction were evaluated. In all, 58 patients with 116 procedural sedations were enrolled. M-K provided a shorter induction time (0:58 vs. 1:23 min) (p = 0.005), but longer sedation (9:02 vs. 5:50 min) (p = 0.019) and emergence time (4:26 vs. 0:56 min) (p = 0.011) compared with M-F. Sedation routes affected the sedation time intervals. Patients had higher rates of vomiting (0, range 0-8 vs. 0, range 0-2) (p = 0.033) but experienced less pain (0 vs. 2) (p = 0.008) in the M-K group. Overall satisfaction and other adverse effects were comparable among both sedation regimens. Combined sedative drugs are recommended to improve the effectiveness of bedside procedural sedation. M-K provided shorter induction, but longer sedation and emergence time compared with M-F. These findings correlated with sedative routes. Patients receiving M-K experienced a higher rate of vomiting, but less painfulness compared with M-F. Overall satisfaction and tolerable side effects were comparable among both sedative regimens.

Early non-excisional debridement of paediatric burns under general anaesthesia reduces time to re-epithelialisation and risk of skin graft. Sci Rep 2021; 11:23753. [PMID: 34887486 PMCID: PMC8660833 DOI: 10.1038/s41598-021-03141-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2021] [Accepted: 11/23/2021] [Indexed: 11/21/2022] Open
Abstract
Reported advantages of early excision for larger burn injuries include reduced morbidity, mortality, and hospital length of stay for adult burn patients. However, a paucity of evidence supports the best option for paediatric burns and the advantages of non-excisional (mechanical) debridement. Procedural sedation and analgesia in the emergency department is a popular alternative to debridement in operating theatres under general anaesthesia. This study aims to evaluate the association between early (< 24 h post-injury) non-excisional debridement under general anaesthesia with burn wound re-epithelialisation time and skin graft requirements. Cohort study of children younger than 17 years who presented with burns of five percent total body surface area or greater. Data from January 2013 to December 2019 were extracted from a prospectively collected state-wide paediatric burns' registry. Time to re-epithelialisation was tested using survival analysis, and binary logistic regression for odds of skin graft requirementto analyse effects of early non-excisional debridement in the operating theatre. Overall, 292 children met eligibility (males 55.5%). Early non-excisional debridement under general anaesthesia in the operating theatre, significantly reduced the time to re-epithelialisation (14 days versus 21 days, p = 0.029)) and the odds of requiring a skin graft in comparison to paediatric patients debrided in the emergency department under Ketamine sedation (OR: 6.97 (2.14-22.67), p < 0.001. This study is the first to demonstrate that early non-excisional debridement under general anaesthesia in the operating theatre significantly reduces wound re-epithelialisation time and subsequent need for a skin graft in paediatric burn patients. Analysis suggests that ketamine procedural sedation and analgesia in the emergency department used for burn wound debridement is not an effective substitute for debridement in the operating theatre.

Abstract
AIMS To determine the grade of sedation in the critically ill paediatric patient using Biespectral Index Sensor (BIS) and to analyse its relationship with sociodemographic and clinical patient variables. METHODS Observational, analytical, cross-sectional and multicentre study performed from May 2018 to January 2020 in 5 Spanish paediatric critical care units. Sex, age, reason for admission, presence of a chronic pathology, type and number of drugs and length of stay were the sociodemographic and clinical variables registered. Furthermore, the grade of sedation was assessed using BIS, once per shift over 24 h. RESULTS A total of 261 paediatric patients, 53.64% of whom were male, with a median age of 1.61 years (0.35-6.55), were included in the study. Of the patients, 70.11% (n = 183) were under analgosedation and monitored using the BIS sensor. A median of BIS values of 51.24 ± 14.96 during the morning and 50.75 ± 15.55 during the night were observed. When comparing BIS values and sociodemographic and clinical paediatric variables no statistical significance was detected. CONCLUSIONS Despite the limitations of the BIS, investigations and the present study show that BIS could be a useful instrument to assess grade of sedation in critically ill paediatric patients. However, further investigations which determine the sociodemographic and clinical variables involved in the grade of paediatric analgosedation, as well as studies that contrast the efficacy of clinical scales like the COMFORT Behaviour Scale-Spanish version, are required.

Abstract
Inherited epidermolysis bullosa (EB) comprises rare disorders that manifest with fragility and blistering of the skin and mucous membranes, with variable clinical severity. Management of EB is challenging due to disease rarity and complexity, the wide range of extracutaneous manifestations and a profound impact on daily life for the patient and family members. Although reference centres providing multidisciplinary care for EB exist in each European country, it is common for healthcare professionals that are not specialized in this rare disorder to treat EB patients. Here, experts of the European Reference Network for Rare and Undiagnosed Skin Diseases (ERN-Skin, https://ern-skin.eu) propose practical recommendations for the diagnosis and management of the commonest clinical issues, skin blisters and wounds, oral manifestations, pain and itch.

Abstract
Procedural sedation and analgesia (PSA) is performed for a variety of indications in emergency departments (EDs). Although the practice of PSA in the ED is somewhat unique from other clinical areas, there is currently no guideline for this practice in Japan. Policy statements and guidelines for PSA have been published in Europe and North America. These guidelines suggest first evaluating patients carefully before performing PSA, and then deciding on target sedative level and choice of medications. Patient evaluation requires a combination of continuous visual observation by trained medical staff to assess the depth of sedation and respiration with noninvasive measurements of blood pressure, continuous electrocardiography monitoring, and pulse oximetry. Sedative selection should be based on its characteristics, peak time, effectiveness, and risks. It is important to administer sedatives and analgesics in small, incremental doses while keeping a close eye on the patient’s reaction to avoid adverse events (AEs) until the planned sedation level is reached. Further, additional attention is needed for special populations such as pediatric and elderly patients. PSA is a key element for patient‐centered care in emergency medicine. In this manuscript, we review the available evidence for PSA in the EDs, including guidelines for evaluation, monitoring, pharmacology, AEs, and special populations such as pediatric and elderly patients.

Abstract
Background and Aims: Ultrasound is a safe and non-invasive method for detecting numerous pathologies. Pediatric patients are often uncooperative which leads to decreased quality and increased time of scan. We compared the conventional means alone and combination of oral midazolam for the above cited purpose. Material and Methods: This double blind prospective study (CTRI/2016/06/007030) was conducted after obtaining due approval from institutional ethical committee. One hundred Children aged 2-6 years belonging to ASA class 1 or 2, posted for high resolution ultrasonography of abdomen were included in the study. They were randomised to receive midazolam 0.3 mg/kg mixed in 20 mL of apple juice (Group I) or 20 mL of apple juice alone (Group II) 20 minutes prior to the procedure. The parameters assessed were level of cooperation, sonologist's satisfaction, total scan time, heart rate and SpO2. Results: Out of 100 patients, 44 patients of group I and 42 of group II were analysed. The cooperation score was significantly higher in Group I (35%) than Group II (19%). Likert scale revealed very satisfied and satisfied rating in 61.3% (Group I) and 21.4% (Group II). The time taken by sonologist and number of attempts were significantly less in Group I than Group II. There was no difference in discharge time between the groups. There was no reportable adverse event in either group. Conclusion: Oral midazolam is a safe and effective agent to aid routine abdominal ultrasonography in pediatric patients.

Abstract
Objective Procedural sedation and analgesia are the standard of care for painful procedures in children that require immobility. The aim is to assess the safety and efficacy of procedural sedation and analgesia in pediatric oncological patients in a large tertiary care hospital. Method An observational study performed to review medical records of children who received procedural sedation and analgesia (PSA) for pediatric oncological procedures from July 2018 to September 2018. Patients undergoing oncology procedures (lumbar puncture, intrathecal chemotherapy, bone marrow aspiration +/- trephine) were included, and non-anesthesiologist (intensive care physician/emergency physician certified in pediatric advanced life support) provided PSA. Patients were assessed according to PSA protocol guidelines by the American Society of Anesthesiology (ASA). Low-dose ketamine (0.5 mg/kg) and propofol (2 mg/kg) were administered. Results A total of 565 children underwent 1216 procedures in whom the median age was 7.4 years, and the majority (65.1%) were males. The most common procedure was the lumbar puncture (n = 956; 78.6%) followed by bone marrow aspirate only (n = 137, 11.3%) and both (n = 123, 10.1%). Eight (0.7%) patients developed transient oxygen desaturation only as an adverse effect of ketamine-propofol drug combination with 50% procedures utilizing propofol 1 mg/kg for sedation. Conclusion According to the results of our study, the majority of the pediatric patients responded and reported no adverse events during the procedure with ketamine and propofol. Therefore, we conclude that ketamine and propofol are safe and effective as both sedative and an analgesic in procedures on pediatric oncology patients.

Abstract
OBJECTIVES Midazolam at a dosage of 0.5 mg/kg induces anxiolytic effects in 90% of children. This study was performed to elucidate whether intravenous midazolam with maternal presence is more efficient than intravenous midazolam alone in the reduction of pain and anxiety of lumbar puncture (LP) in 6 to 24-month-old children. MATERIALS & METHODS In this not-blinded clinical trial, we included 60 children aged 6 to 24 months old undergoing LP in the Pediatric Ward of Shahid Sadoughi Hospital, Yazd, Iran, from September 2014 to March 2015. The participants were randomly assigned to two groups, and all of them received painless injection of 0.5 mg/kg midazolam five minutes before LP. In group I, LP was performed with maternal presence and in group II, the mothers were absent. The primary outcomes included anxiety and pain scores before LP and during needle insertion to the skin for LP. The secondary outcomes comprised of success rates in the reduction of anxiety (anxiety score of four and more) and pain (pain score of less than three) when the needle was inserted to the skin for LP. RESULTS Twenty-eight girls and 32 boys were evaluated in the two groups. Maternal presence was found to be effective in the reduction of anxiety (2.7±0.65 vs. 3.83±0.87; P=0.001) and pain scores (3.8±1.75 vs. 6.1±1.63, P=0.001). In the maternal presence group, success rate in anxiety (76.7% vs. 16.6%; P=0.0001) and pain reduction (63.3 % vs. 6.7%; P=0.0001) was higher than in the midazolam alone group. CONCLUSION Maternal presence during lumbar puncture can reduce pain and anxiety among 6 to 24-month-old children.

Combined Treatment with Low-Dose Ionizing Radiation and Ketamine Induces Adverse Changes in CA1 Neuronal Structure in Male Murine Hippocampi. Int J Mol Sci 2019; 20:ijms20236103. [PMID: 31817026 PMCID: PMC6929167 DOI: 10.3390/ijms20236103] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2019] [Revised: 11/29/2019] [Accepted: 12/02/2019] [Indexed: 12/13/2022] Open
Abstract
In children, ketamine sedation is often used during radiological procedures. Combined exposure of ketamine and radiation at doses that alone did not affect learning and memory induced permanent cognitive impairment in mice. The aim of this study was to elucidate the mechanism behind this adverse outcome. Neonatal male NMRI mice were administered ketamine (7.5 mg kg−1) and irradiated (whole-body, 100 mGy or 200 mGy, 137Cs) one hour after ketamine exposure on postnatal day 10. The control mice were injected with saline and sham-irradiated. The hippocampi were analyzed using label-free proteomics, immunoblotting, and Golgi staining of CA1 neurons six months after treatment. Mice co-exposed to ketamine and low-dose radiation showed alterations in hippocampal proteins related to neuronal shaping and synaptic plasticity. The expression of brain-derived neurotrophic factor, activity-regulated cytoskeleton-associated protein, and postsynaptic density protein 95 were significantly altered only after the combined treatment (100 mGy or 200 mGy combined with ketamine, respectively). Increased numbers of basal dendrites and branching were observed only after the co-exposure, thereby constituting a possible reason for the displayed alterations in behavior. These data suggest that the risk of radiation-induced neurotoxic effects in the pediatric population may be underestimated if based only on the radiation dose.

Abstract
Introduction Pediatric patients require deep sedation at least for cardiac catheterizations (CCs). Usually, we perform these CCs applying propofol, but we have seen several side effects of this sedative. We have had good experience with 4-hydroxybutyric acid for other sedations. To optimize our standardized CC procedure, we initiated a prospective, randomized trial to compare the two substances. Methods We analyzed our sedation protocols of all CCs within a period of 12 months. In addition to the primary endpoints, the feasibility of the CCs and the occurrence of severe complications, several other parameters were included in the analysis (vital parameters, blood gas analysis, intervention measures). The protocols were blinded for the first part of the evaluation. Results During the 12-month-period, 36 patients were included in each group. The propofol group showed lower blood pressure values towards the end of the sedations, while the blood gas analyses revealed lower pH levels and higher pCO2 values. The complication rate was low in both groups. Conclusion Both procedures are suited for the safe performance of deep sedations for CCs. The application of 4-hydroxybutyric acid seems to have a few advantages with regard to spontaneous breathing, gas exchange, stability of cardiocirculatory parameters and sedation quality.

Humanization interventions in general pediatric wards: a systematic review. Eur J Pediatr 2019; 178:607-622. [PMID: 30949888 DOI: 10.1007/s00431-019-03370-3] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2018] [Revised: 02/23/2019] [Accepted: 03/20/2019] [Indexed: 02/07/2023]
Abstract
Humanization of care (HOC) interventions have rarely been evaluated and compared. We systematically reviewed the outcomes of published interventions aimed to improve the HOC for hospitalized children. PubMed and Scopus were used as data sources. Studies published between January 1, 2000, and February 28, 2018, were considered eligible if they reported analysis of results vs. either a control group or baseline, or if they measured patient/family/staff satisfaction. Neonatal age, emergency departments, and subspecialty settings were excluded. Data were extracted using a standardized data extraction form including study design, sample size, intervention, outcome/objective, and evaluation of results or pre- post-intervention satisfaction. Twenty-eight of the 12,012 retrieved articles met the inclusion criteria. Most studies were of moderate to low quality. Only six studies were of high quality. Areas of interest dealt with environment (n = 4), provider-patient relationship (n = 6), pet therapy (n = 5), technology (n = 5), family-centered rounds (n = 2), psychological support (n = 3), and staff training (n = 3). The overall trend of the results indicated that interventions were mostly effective and likely to have beneficial effects on several aspects of pediatric hospitalization.Conclusions: Pending further studies of better research quality, the findings of this review may have policy and practice implications for planning HOC interventions by pediatric healthcare professionals. What is Known: • In pediatrics, humanization of care (HOC) provides assistance focused not only on the child as a patient, but on the whole family. • HOC programs have been developed, but information on the overall outcome of local projects aiming to improve in a practical way the hospital taking charge of pediatric patients is still lacking. What is New: • Local HOC interventions are mostly effective and have beneficial effects on several aspects of hospitalization in general pediatrics wards. • The findings of this review may have practice implications for planning HOC interventions by pediatric healthcare professionals.

Abstract
Objective Studies have suggested that pre-emptive analgesia may decrease postoperative pain and opioid consumption. This study was undertaken to determine whether pre-emptive analgesia reduces postoperative pain and total paracetamol and opioid consumption in children undergoing herniorrhaphy. Methods In this retrospective study, medical records were analysed before and after the pre-emptive analgesia regimen was introduced. Demographic data, perioperative drug consumption and discharge time were recorded. In the first group, no pre-emptive analgesia (NA; year, 2011; n=60) was given and in the second group, the pre-emptive analgesia (PA) paracetamol 10-15 mg kg-1 was given intravenously in the surgical ward at least 1 h before the surgical procedure (year 2013; n=60). Postoperative pain determining supplemental pain medications was scored using a Faces Pain Scale or visual analogue scale. Total paracetamol and opioid consumption during 24 perioperative hours was registered for all patients. The statistical analysis was performed using t test and Chi-square test. Results The mean age of children was 69.6±49.9 and 58.7±32.4 months (p=0.157), and the mean body mass index (BMI) was 18.3±8.8 kg m-2 and 16.4±3.7 kg m-2 (p=0.125) in the NA and PA groups, respectively. Total paracetamol consumption was 1157.8±908.8 mg vs. 983.0±536.4 mg (p=0.202), and the total opioid consumption was 5.8±4.7 in the NA group and 7.0±4.6 morphine equivalents in the PA group (p=0.160). No differences in the discharge time between the groups were observed (2.1±0.3 vs. 2.0±0.3 days, p=0.13). Conclusion PA was proven to be efficient in the terms of postoperative pain control but did not reduce the overall analgesic drug consumption in the children undergoing elective herniorrhaphy. Multimodal pain treatment may decrease the consumption of analgesic drugs.

A comparison of ketamine + midazolam to propofol for procedural sedation for lumbar puncture in pediatric oncology by nonanesthesiologists-a randomized comparative trial. Pediatr Blood Cancer 2018; 65:e27108. [PMID: 29727056 DOI: 10.1002/pbc.27108] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2018] [Revised: 03/06/2018] [Accepted: 04/02/2018] [Indexed: 02/03/2023]
Abstract
BACKGROUND Both ketamine-midazolam and propofol are frequently used in pediatric oncology units for procedural sedation. However, there are no prospective, randomized comparative trials (RCT) comparing the two groups when the procedure is performed by nonanesthesiologists. OBJECTIVE To compare ketamine + midazolam (group A) and propofol (group B) as sedative agents for intrathecal chemotherapy with regard to efficacy, side effects, time to induction, time to recovery, and smoothness of recovery. METHODS A partially-blinded RCT was conducted between August 2015 and March 2017 after gaining institutional ethics committee approval. Children aged 1-12 years requiring intravenous sedation for intrathecal chemotherapy were included. Patients were allocated to two treatment arms using computer-generated randomization tables, after obtaining written consent. The initial doses used were: ketamine 2 mg/kg, midazolam 0.2 mg/kg, and propofol 2.5 mg/kg, as per standard recommendations. The patient, parents, and person analyzing the data were blinded. Time to sedation, dose required, depth of sedation, vital parameters, time and smoothness of recovery, and emergence phenomena were documented. RESULTS We enrolled 152 patients (76 each in group A and B). Nine patients had a failure of sedation (all in group B). Mean time to sedation and recovery was shorter in group B (P < 0.001). Transient drop in saturation was more frequent in group B, without statistical significance (P = 0.174). Mean depth of sedation was greater in group A (P < 0.001). Emergence symptoms were more frequently experienced in group A (P < 0.001). CONCLUSIONS Ketamine-midazolam combination is safer and more effective. Propofol is faster in onset and recovery, and has smoother emergence with poor efficacy at recommended initial doses.

Clin Ther 2016; 38:1522-1529. [PMID: 27229908 DOI: 10.1016/j.clinthera.2016.04.036] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2016] [Revised: 04/20/2016] [Accepted: 04/25/2016] [Indexed: 10/21/2022]
Abstract
PURPOSE It is a challenge to rescue ophthalmology examinations performed in children in the sedation room after initial chloral hydrate failure. Intranasal dexmedetomidine can be used in rescue sedation in children undergoing computed tomography. The present study aimed to assess the efficacy and tolerability of intranasal dexmedetomidine use in children undergoing ophthalmic examination after chloral hydrate failure. METHODS Sixty uncooperative pediatric patients with cataract (aged 5-36 months; weight, 7-15 kg) presented for follow-up ophthalmic examination. Patients who experienced chloral hydrate failure were randomized to 1 of 2 groups to receive intranasal dexmedetomidine 1 or 2 μg/kg for rescue sedation. Each group contained 30 patients. The primary outcome was the rate of a successful ophthalmic examination. Secondary outcomes included sedation onset time, recovery time, duration of examination, discharge time, and adverse events, including percentage of heart rate reduction, respiratory depression, vomiting, and postsedative agitation. FINDINGS A successful ophthalmic examination was achieved in 93.3% (28/30) of patients in the 2-μg/kg dose group and in 66.7% (20/30) of patients in the 1-μg/kg dose group (P = 0.021). The onset time, recovery time, and discharge time did not significantly differ between the 2 groups. None of the patients required clinical intervention due to heart rate reduction, and none of the patients in either group experienced vomiting, respiratory depression, or agitation after the administration of dexmedetomidine. IMPLICATIONS In children undergoing ophthalmic examination, intranasal dexmedetomidine can be administered in the sedation room for rescue sedation after chloral hydrate failure, with the 2-μg/kg dose being more efficacious than the 1-μg/kg dose, as measured by success rate. ClinicalTrials.gov identifier: NCT02077712.

Abstract
BACKGROUND Sedation is increasingly used to facilitate procedures on children in emergency departments (EDs). This overview of systematic reviews (SRs) examines the safety and efficacy of sedative agents commonly used for procedural sedation in children in the ED or similar settings. METHODS We followed standard SR methods: comprehensive search; dual study selection, quality assessment, data extraction. We included SRs of children (1 month to 18 years) where the indication for sedation was procedure-related and performed in the ED. RESULTS Fourteen SRs were included (210 primary studies). The most data were available for propofol (six reviews/50,472 sedations) followed by ketamine (7/8,238), nitrous oxide (5/8,220), and midazolam (4/4,978). Inconsistent conclusions for propofol were reported across six reviews. Half concluded that propofol was sufficiently safe; three reviews noted a higher occurrence of adverse events, particularly respiratory depression (upper estimate 1.1%; 5.4% for hypotension requiring intervention). Efficacy of propofol was considered in four reviews and found adequate in three. Five reviews found ketamine to be efficacious and seven reviews showed it to be safe. All five reviews of nitrous oxide concluded it is safe (0.1% incidence of respiratory events); most found it effective in cooperative children. Four reviews of midazolam made varying recommendations. To be effective, midazolam should be combined with another agent that increases the risk of adverse events (upper estimate 9.1% for desaturation, 0.1% for hypotension requiring intervention). CONCLUSIONS This comprehensive examination of an extensive body of literature shows consistent safety and efficacy for nitrous oxide and ketamine, with very rare significant adverse events for propofol. There was considerable heterogeneity in outcomes and reporting across studies and previous reviews. Standardized outcome sets and reporting should be encouraged to facilitate evidence-based recommendations for care.

Neuroprotective effect of dexmedetomidine on hyperoxia-induced toxicity in the neonatal rat brain. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2015; 2015:530371.

Abstract
Dexmedetomidine is a highly selective agonist of α2-receptors with sedative, anxiolytic, analgesic, and anesthetic properties. Neuroprotective effects of dexmedetomidine have been reported in various brain injury models. In the present study, we investigated the effects of dexmedetomidine on neurodegeneration, oxidative stress markers, and inflammation following the induction of hyperoxia in neonatal rats. Six-day-old Wistar rats received different concentrations of dexmedetomidine (1, 5, or 10 µg/kg bodyweight) and were exposed to 80% oxygen for 24 h. Sex-matched littermates kept in room air and injected with normal saline or dexmedetomidine served as controls. Dexmedetomidine pretreatment significantly reduced hyperoxia-induced neurodegeneration in different brain regions of the neonatal rat. In addition, dexmedetomidine restored the reduced/oxidized glutathione ratio and attenuated the levels of malondialdehyde, a marker of lipid peroxidation, after exposure to high oxygen concentration. Moreover, administration of dexmedetomidine induced downregulation of IL-1β on mRNA and protein level in the developing rat brain. Dexmedetomidine provides protections against toxic oxygen induced neonatal brain injury which is likely associated with oxidative stress signaling and inflammatory cytokines. Our results suggest that dexmedetomidine may have a therapeutic potential since oxygen administration to neonates is sometimes inevitable.
