RESUMEN
Background: Individual implementation rate of bronchoscopy-guided percutaneous dilatational tracheostomy (PDT) varies among intensivists. Simulation training (ST) can increase the safety of medical procedures by reducing stress levels of the performing team. The aim of this study was to evaluate the benefit of ST in PDT regarding procedural time, quality of performance, and percepted feelings of safety of the proceduralist and to compare conventional simulators (CSIM) with simulators generated from 3D printers (3DSIM). Methods: We conducted a prospective, single-center, randomized, blinded cross-over study comparing the benefit of CSIM versus 3DSIM for ST of PDT. Participants underwent a standardized theoretical training and were randomized to ST with CSIM (group A) or 3DSIM (group B). After ST, participants' performance was assessed by two blinded examiners on a porcine trachea regarding time required for successful completion of PDT and correct performance (assessed by a performance score). Percepted feelings of safety were assessed before and after ST. This was followed by a second training and second assessment of the same aspects with crossed groups. Results: 44 participants were included: 24 initially trained with CSIM (group A) and 20 with 3DSIM (group B). Correctness of the PDT performance increased significantly in group B (p < .01) and not significantly in group A (p = .14). Mean procedural time required for performing a PDT after their second ST compared to the first assessment (p < .01) was lower with no difference between group A and group B and irrespective of the participants' previous experience regarding PDT, age, and sex. Moreover, percepted feelings of safety increased after the first ST in both groups (p < .001). Conclusions: ST can improve procedural skills, procedural time, and percepted feelings of safety of the proceduralist in simulated PDT.

BACKGROUND: Paediatric early warning score systems are used for early detection of clinical deterioration of patients in paediatric wards. Several paediatric early warning scores have been developed, but most of them are not suitable for children with cyanotic CHD who are adapted to lower arterial oxygen saturation. AIM: The present study compared the original paediatric early warning system of the Royal College of Physicians of Ireland with a modification for children with cyanotic CHD. DESIGN: Retrospective single-centre study in a paediatric cardiology intermediate care unit at a German university hospital. RESULTS: The distribution of recorded values showed a significant shift towards higher score values in patients with cyanotic CHD (p < 0.001) using the original score, but not with the modification. An analysis of sensitivity and specificity for the factor "requirement of action" showed an area under the receiver operating characteristic for non-cyanotic patients of 0.908 (95% CI 0.862-0.954). For patients with cyanotic CHD, using the original score, the area under the receiver operating characteristic was reduced to 0.731 (95% CI 0.637-0.824, p = 0.001) compared to 0.862 (95% CI 0.809-0.915, p = 0.207), when the modified score was used. Using the critical threshold of scores ≥ 4 in patients with cyanotic CHD, sensitivity and specificity for the modified score was higher than for the original (sensitivity 78.8 versus 72.7%, specificity 78.2 versus 58.4%). CONCLUSION: The modified score is a uniform scoring system for identifying clinical deterioration, which can be used in children with and without cyanotic CHD.

Background and Objectives: Enucleation of an eye is the most invasive procedure in ophthalmologic surgery. It can be the result of various diseases (malignant/chronic/trauma/infection) and is nevertheless relatively rare, but leads to the loss of a strongly innervated neuronal organ. This study systematically evaluates postoperative pain levels following enucleation of the eye globe. Materials and Methods: This prospective single-center study enrolled twenty-four patients undergoing enucleation of the eye globe. Perioperatively all patients completed (preoperative day, day of surgery, 1st, 2nd, and 3rd day following surgery) standardized questionnaires concerning their pain experience and treatment-related side-effects (internal protocol, QUIPS, painDETECT®). Patients received usual pain therapy in an unstandardized individual manner. Results: Preoperatively, mean average pain intensity of all included patients was 3.29 ± 2.46 (range, 0-8), 3.29 ± 3.24 (range, 0-8) on the day of surgery, 4.67 ± 1.90 (range, 2-10) on day 1, 3.25 ± 1.39 (range, 1-6) on day 2, and 2.71 ± 1.30 (range, 1-6) on day 3 after surgery. Mean maximum pain intensity was 4.71 ± 3.28 (range, 0-10) preoperatively, 4.04 ± 3.78 (range, 0-10) on the day of surgery, 5.75 ± 2.01 (range, 2-10) on day 1, 4.25 ± 1.89 (range, 2-10) on day 2, and 3.88 ± 1.54 (range, 2-8) on day 3 after surgery. Nineteen patients (79.2%) stated that they would have preferred more pain therapy. Conclusions: Patients undergoing eye enucleation report pain sensations in need of intervention in this university hospital. Thus, effective standardized pain treatment concepts are now a high priority to be established in an interdisciplinary manner containing standardized regimens and continuous regional procedures. Awareness of this problem in the medical team should be sharpened through targeted training and information.

BACKGROUND: Patients undergoing corneal abrasion as part of Descemet membrane endothelial keratoplasty (DMEK) under general anesthesia suffer from early burning pain postoperatively. This pain appears to be poorly treatable with systemic analgesics. This study aims to evaluate postoperative pain management using topical lidocaine gel after DMEK with iatrogenic corneal abrasion. METHODS: Retrospective analysis of 28 consecutive patients undergoing DMEK with corneal abrasion from October 19, 2021, to November 12, 2021, at a German university hospital. Patients during week 1 and 2 received peri-operative standard pain treatment (cohort S) and additional local lidocaine gel during week 3 and 4 immediately postoperatively (cohort L). RESULTS: 13 patients were included in cohort S and 15 patients in cohort L. At awakening all patients (100%) in cohort S reported burning pain, and six of 15 patients (40%) in cohort L reported burning pain. Burning pain scores were significantly lower in cohort L (p < 0.001 at awakening, p < 0.001 at 10 min, p < 0.001 at 20 min, p < 0.001 at 30 min, p = 0.007 at 40 min after awakening, and p < 0.001 at leaving recovery room). No significant differences between cohort S and cohort L were detected concerning surgical outcome during 1-month-follow-up (p = 0.901 for best corrected visual acuity). CONCLUSION: Patients undergoing DMEK with corneal abrasion suffer significant pain in the recovery room. A single dose of topic lidocaine gel reduces the early postoperative burning pain sufficiently and does not affect the surgical outcome.

INTRODUCTION: This study investigates the hygiene standards in the context of the COVID-19 pandemic and their impact on the perioperative incidence of human metapneumovirus as well as the typical symptom burden of human metapneumovirus-infected children with CHDs. MATERIALS AND METHODS: Between March 2018 and July 2021, all patients of a cardiac paediatric ICU of a German university hospital were included in this retrospective cohort analysis. RESULTS: A total of 589 patients with CHD were included in the analysis. Three hundred and fifty-two patients (148 females and 204 males) were admitted before the introduction of social distancing and face masks between March 2018 and 15 April 2020 (cohort A). Two hundred and thirty-seven patients (118 females and 119 males) were admitted after the introduction between April 16 and July 2021 (cohort B). In cohort A, human metapneumovirus was detected in 11 out of 352 patients (3.1%) during their stay at cardiac paediatric ICU. In cohort B, one patient out of 237 (0.4%) tested positive for human metapneumovirus. Patients who tested positive for human metapneumovirus stayed in cardiac paediatric ICU for a median of 17.5 days (range, 2-45 days). Patients without a detected human metapneumovirus infection stayed in the cardiac paediatric ICU for a median of 4 days (range, 0.5-114 days). Nine out of 12 (75%) human metapneumovirus-positive patients showed atelectasis. CONCLUSION: Perioperative human metapneumovirus infections prolong cardiac paediatric ICU stay in children with CHD. In affected patients, pulmonary impairment with typical symptoms appears. Under certain circumstances, a complication-rich perioperative infection with human metapneumovirus could be prevented in paediatric cardiac high-risk patients by prophylactic hygiene intervention.

Constant medical progress leads to an increasing range of indications and consequently increasing number of diagnostic procedures in (early) childhood. To prevent lasting traumatization of children (and parents) and to ensure proper examination conditions, adequate (analgo-)sedation or general anesthesia is usually required for the appropriate management of diagnostic procedures in childhood, whether painful or not. The safety of young patients is the first priority. Administrations, hospitals, and each individual anesthesiologist are responsible for establishing structures, experience, and knowledge in this area so that children of all ages receive optimum care. In this article, the authors provide an overview of basic principles (structures, requirements, recommendations), currently used drugs, and procedure-specific examples for providing procedural analgosedation/anesthesia in children.

BACKGROUND: Many different sedation concepts for magnetic resonance imaging have been described for prematurely and term-born infants, ranging from "no sedation" to general anesthesia. Dexmedetomidine is an alpha-2 receptor agonist that is frequently used to sedate older children, because the anesthesiologist can easily adjust sedation depth, the patient maintains spontaneous breathing, and awakens rapidly afterwards. AIMS: The present study evaluates whether dexmedetomidine could safely be used as the sole sedative for prematurely and term-born infants less than 60 weeks postconceptional age undergoing diagnostic procedures. METHODS: We performed a retrospective monocentric analysis of n = 39 prematurely and term-born infants (<60 weeks postconceptional age or a body weight <5 kg) who were sedated with dexmedetomidine for an MRI at a German university hospital from August 2016 to November 2018. RESULTS: Successful imaging was achieved in all cases. The median initial bolus of dexmedetomidine administered over 10 min was 1.39 µg kg-1 body weight (range 0.34-3.64 µg kg-1 ), followed with a continuous infusion at a median rate of 1.00 µg kg-1 h-1 (range 0.5-3.5 µg kg-1 h-1 ); however, 3 patients (7%) needed some additional sedation (ketamine or propofol). All patients, including 10 infants who had previously required respiratory support, underwent the procedure without any relevant desaturation or apnea. Bradycardia was observed in up to 15 out of 39 cases (38.5%), but only four (10.3% in total and 26.7% of bradycardia) required atropine. CONCLUSIONS: These results indicate that dexmedetomidine can be safely used for procedural sedation in the high-risk cohort of prematurely and term-born infants less than 60 weeks postconceptional age. Apnea during procedural sedation and subsequent stay in the recovery room is avoided, but bradycardia remains a relevant risk that may require treatment.

Induction of anesthesia by inhalation is very common in children due to difficult venous conditions and especially in uncooperative children. During the study on complications in the pediatric anesthesia in Europe (APRICOT study) including almost 30,000 patients, 48% of the children were induced by inhalation.Under the conditions of the corona pandemic, however, induction of anesthesia by inhalation represents an increased risk of infection due to the potential release of aerosols. Rapid sequence induction is recommended for anesthesia induction and definitive airway management for adults and children in the current pandemic situation.The present case demonstrates that there can be situations in children in which induction of anesthesia by inhalation is unavoidable and shows a potential procedure for reducing the risk of infection for the anesthesia personnel.

BACKGROUND: B-lines as typical artefacts of lung ultrasound are considered as surrogate measurement for extravascular lung water. However, B-lines develop in the sub-pleural space and do not allow assessment of the whole lung. Here, we present data from the first observational multi-centre study focusing on the correlation between a B-lines score and extravascular lung water in critically ill patients suffering from a variety of diseases. PATIENTS AND METHODS: In 184 adult patients, 443 measurements were obtained. B-lines were counted and expressed in a score which was compared to extravascular lung water, measured by single-indicator transpulmonary thermodilution. Appropriate correlation coefficients were calculated and receiver operating characteristics (ROC-) curves were plotted. RESULTS: Overall, B-lines score was correlated with body weight-indexed extravascular lung water characterized by r = .59. The subgroup analysis revealed a correlation coefficient in patients without an infection of r = .44, in those with a pulmonary infection of r = .75 and in those with an abdominal infection of r = .23, respectively. Using ROC-analysis the sensitivity and specificity of B-lines for detecting an increased extravascular lung water (>10 mL/kg) was 63% and 79%, respectively. In patients with a P/F ratio <200 mm Hg, sensitivity and specificity to predict an increased extravascular lung water was 71% and 93%, respectively. CONCLUSIONS: Assessment of B-lines does not accurately reflect actual extravascular lung water. In presence of an impaired oxygenation, B-lines may reliably indicate increased extravascular lung water as cause of the oxygenation disorders.

Background: The use of laryngeal masks in the surgical treatment of infantile lacrimal duct stenosis is controversial due to the potential risk of aspiration. Aims: This study investigates airway procedures in children aged <6 years for surgery of lacrimal duct stenosis in a tertiary care university hospital. Methods: After institutional approval, airway procedures, duration of anesthesiological measures, and airway-related complications were retrospectively analyzed. Patients were divided into two groups according to the airway procedures used (endotracheal tube [ET] vs. laryngeal mask [LMA] airway). Associations were calculated using the Chi-square test or Mann-Whitney U-test. Results: Clinical data of 84 patients (ET n = 36 [42.9%] vs. LMA n = 48 [57.1%]) were analyzed. There were no significant differences in surgical treatment, age distribution, and pre-existing conditions between the groups. None of the patients showed evidence of tracheal aspiration or changes in measured oxygen saturation. LMA airway shortened time for anesthesia induction (p = 0.006) and time for recovery/emergence period (p = 0.03). In contrast, the time to discharge from the recovery room was significantly prolonged using LMA (p = 0.001). A total of 7 adverse events were recorded. Five of these were directly or indirectly related to ET (laryngo-/bronchospasm; muscle relaxant residual). Conclusions: LMA airway for infantile lacrimal duct stenosis seems to be a safe procedure and should be used in appropriate pediatric patients due to its lower invasiveness, low complication rate, and time savings.
RESUMEN
The reduction of greenhouse gases such as CO2 emissions and their equivalents (CO2e) generally has three aspects: Fugitive direct emissions (anesthetic gases, exhaust gases), indirect emissions through the purchase of energy (electricity, heat) and emissions in the supply chain (supply of consumables, disposal). Since pediatric anesthesia has a traditional affinity with inhalation, the use of anesthetic gases should be repeatedly questioned and, if possible, avoided on the way to net zero emissions in addition to general measures to conserve resources. In children, analgosedation, total intravenous anesthesia (TIVA) and establishment of venous access prior to the induction of anesthesia are particularly suitable for this purpose. In addition to avoiding greenhouse gases, the methods mentioned offer other significant medical advantages and can also be profitable in terms of safety and comfort. Nevertheless, anesthetic gases are required in pediatric anesthesia in some situations. For this reason, it is important to save anesthetic gases through minimal fresh gas flow and a rational approach to inhalation induction. To facilitate implementation in clinical practice, this article provides recommendations for mask induction and choice of anesthetic procedure.

For many years the quality of perioperative pain management in general has been repeatedly reported as inadequate and there is significant evidence to indicate that this is also true after surgical procedures in ophthalmology. The patient population in ophthalmology is quite challenging due to numerous comorbidities and a high average age resulting in numerous contraindications and organ dysfunctions and requiring special knowledge to ensure high quality acute pain management. The following overview covers basic knowledge of acute pain management, with a particular focus on analgesic approaches and the specifics of the patient population and the associated limitations in terms of analgesic and co-analgesic pharmacological options.

Patient-centered and adequate postoperative pain management is an important part of a modern treatment concept and should also be standard in ophthalmology. Due to the "Regulation on the mandatory introduction and implementation of acute pain management concepts for adequate postoperative pain therapy" prescribed by the Federal Joint Committee of the German statutory healthcare system (G-BA), hospitals and outpatient facilities have been required to have regulations on pain management in place since 9 December 2020. It is very likely that the need of pain management in ophthalmic surgery has been systematically underestimated so far and studies on postoperative pain hardly exist. In the opinion of the authors, the decision represents an opportunity to pay more attention to the topic and to develop standards for ophthalmology as well. This article explains the GBA decision and the resulting consequences for ophthalmic surgical institutions.

Pain following eye surgery is often described as being relatively moderate; however, there are also procedures that lead to a pronounced pain experience. Particularly in pediatric patients, pain therapy is often insufficient due to a lack of knowledge and fear of complications. These individual and organizational deficits lead to unnecessary discomfort for children and parents. Each institution providing surgical treatment must have pain management concepts in its portfolio for the appropriate age groups. This includes a child-oriented setting, age-appropriate information, systematic pain assessment, and pain protocols. Pain management should be planned prior to surgery and individually adapted as it progresses. Children have a right to a perioperative course with low stress and pain.

BACKGROUND/AIMS: Perioperative pain in children is often inadequately treated, and emergence agitation is common. The purpose of this analysis was to determine whether nalbuphine is suitable for perioperative eye pain and to analyse if it influences the occurrence of emergence delirium/agitation (EDA) in children undergoing ophthalmic surgery in general anaesthesia. METHODS: Retrospective cohort analysis of 50 children in preschool age undergoing general anaesthesia for ophthalmic surgery receiving nalbuphine as a postoperative analgesic in a German university hospital from June 2020 to February 2021.Scores and values for pain and EDA were routinely recorded after awakening and during the stay in the recovery room. Data were evaluated retrospectively from the medical records. RESULTS: A total of 50 children (17 girls and 33 boys) underwent general anaesthesia for ophthalmic surgery. The median age of the children included was 20.5 months (range, 1-68 months), the median body weight was 12.25 kg (range, 2.9-29 kg). All patients received ibuprofen (10 mg/kg1) during induction of anaesthesia and nalbuphine (0.1 mg/kg) at the end of surgery. All patients had an Paediatric-Anaesthesia-Emergence-Delirium-I-score (PAED-ED-I Score) of less than 6 and acceptable Face-Legs-Activity-Cry-Consolability-scores (FLACC less than 3) on waking and on leaving the recovery room. CONCLUSION: Nalbuphine shows a sufficient analgesic effect for pain therapy following ophthalmic surgery in preschool children. Nalbuphine seems to reduce the incidence of EDA in children undergoing ophthalmic surgery.

We report two cases of neonates with complex congenital heart disease and volume, catecholamine, and corticosteroid refractory shock treated with arginine-vasopressin. Arginine-vasopressin was able to reverse critical hypotension, but both patients developed severe hyponatremia, which recovered after discontinuation of arginine-vasopressin. Close control and prompt substitution of serum sodium is required in neonates with advanced heart failure on high-dose vasopressin therapy.
