Advanced CT measures of coronary artery disease with intermediate stenosis in patients with severe aortic valve stenosis.

BACKGROUND: Coronary artery disease (CAD) and severe aortic valve stenosis (AS) frequently coexist. While pre-transcatheter aortic valve replacement (TAVR) computed tomography angiography (CTA) allows to rule out obstructive CAD, interpreting hemodynamic significance of intermediate stenoses is challenging. This study investigates the incremental value of CT-derived fractional flow reserve (CT-FFR), quantitative coronary plaque characteristics (e.g., stenosis degree, plaque volume, and composition), and peri-coronary adipose tissue (PCAT) density to detect hemodynamically significant lesions among those with AS and CAD. MATERIALS AND METHODS: We included patients with severe AS and intermediate coronary lesions (20-80% diameter stenosis) who underwent pre-TAVR CTA and invasive coronary angiogram (ICA) with resting full-cycle ratio (RFR) assessment between 08/16 and 04/22. CTA image analysis included assessment of CT-FFR, quantitative coronary plaque analysis, and PCAT density. Coronary lesions with RFR ≤ 0.89 indicated hemodynamic significance as reference standard. RESULTS: Overall, 87 patients (age 77.9 ± 7.4 years, 38% female) with 95 intermediate coronary artery lesions were included. CT-FFR showed good discriminatory capacity (area under receiver operator curve (AUC) = 0.89, 95% confidence interval (CI) 0.81-0.96, p < 0.001) to identify hemodynamically significant lesions, superior to anatomical assessment, plaque morphology, and PCAT density. Plaque composition and PCAT density did not differ between lesions with and without hemodynamic significance. Univariable and multivariable analyses revealed CT-FFR as the only predictor for functionally significant lesions (odds ratio 1.28 (95% CI 1.17-1.43), p < 0.001). Overall, CT-FFR ≤ 0.80 showed diagnostic accuracy, sensitivity, and specificity of 88.4% (95%CI 80.2-94.1), 78.5% (95%CI 63.2-89.7), and 96.2% (95%CI 87.0-99.5), respectively. CONCLUSION: CT-FFR was superior to CT anatomical, plaque morphology, and PCAT assessment to detect functionally significant stenoses in patients with severe AS. CLINICAL RELEVANCE STATEMENT: CT-derived fractional flow reserve in patients with severe aortic valve stenosis may be a useful tool for non-invasive hemodynamic assessment of intermediate coronary lesions, while CT anatomical, plaque morphology, and peri-coronary adipose tissue assessment have no incremental or additional benefit. These findings might help to reduce pre-transcatheter aortic valve replacement invasive coronary angiogram. KEY POINTS: • Interpreting the hemodynamic significance of intermediate coronary stenoses is challenging in pre-transcatheter aortic valve replacement CT. • CT-derived fractional flow reserve (CT-FFR) has a good discriminatory capacity in the identification of hemodynamically significant coronary lesions. • CT-derived anatomical, plaque morphology, and peri-coronary adipose tissue assessment did not improve the diagnostic capability of CT-FFR in the hemodynamic assessment of intermediate coronary stenoses.

Inpatient Rsv-Management 2016-2022: Epidemiology and Adherence to A Bronchiolitis Treatment Standard at a German University Children's Hospital.

BACKGROUND: This study analyzes the RSV season 2021/2022 in a referral children's hospital, compares the epidemiology and illness severity with RSV-infected inpatients from 2016 to 2020 and audits the adherence to our internal therapy standard for RSV bronchiolitis. MATERIAL AND METHODS: Inpatients with rtPCR-confirmed RSV infection (Jan. 2016 to Jan. 2022). RESULTS: The audit comprises 306 RSV inpatients, on average 50 hospitalizations per year; in 03/2020, a rapid RSV Season-Offset was observed. In the winter season 2020/2021, no patient with RSV was hospitalized. Beginning in July, we noticed a rapid increase of RSV-admissions (most cases in Sept./Oct, duration until Dec. 2021; n=53). In 2021-2022, a significant larger share needed PICU admission (9.4% vs 3.2%, p=0.040). Adherence to the internal guidance was low; only 11.8% (n=36) of all patients received supportive treatment without inhalative or systemic medications, 37% of all patients received antibiotics. CONCLUSIONS: This audit confirms the strong impact of public preventive measures directed against SARS-CoV-2 transmission on RSV epidemiology. Few weeks after easing public COVID-19 restrictions (summer 2021), RSV inpatient cases rapidly increased, lasting until Dec. 2021. The audit of bronchiolitis management revealed surprisingly low adherence to the internal guidance, despite a face-to-face educational session with the attending pediatricians in Oct. 2021. Low adherence resulted in an unnecessary exposure of RSV patients to systemic medications of questionable benefit including antibiotics.

Study draft: "UVC-You Will See" study: longer vs. shorter umbilical venous catheter (UVC) dwell time (6-10 vs. 1-5 days) in very premature infants with birth weight < 1250 g and/or gestational age < 30 weeks.

BACKGROUND: Umbilical venous catheters (UVCs) are often used in preterm infants. Their use is associated with complications (infections, clot formation, organ injury). Very preterm infants with acquired bloodstream infection are at a higher risk for death and important morbidities (e.g., adverse neurodevelopmental outcomes). It is standard clinical practice to remove UVCs in the first days of life. Replacement of intravenous access is often performed using percutaneously inserted central catheters (PICCs). It is unclear whether serial central line use affects the rates of catheter-related complications. METHODS: A multicenter randomized controlled trial (random group assignment) was performed in 562 very premature (gestational age < 30 weeks) and/or very low birth weight infants (< 1250 g) requiring an UVC for administration of parenteral nutrition and/or drugs. Group allocation was random. HYPOTHESIS: A UVC dwell time of 6-10 days (281 infants) is not associated with an increased rate of central venous catheter (UVC, PICC)-related complications compared to 1-5 days (281 infants), and a longer UVC dwell time will significantly reduce the number of painful, invasive procedures associated with the need for vascular access as well as radiation exposure, use of antibiotics, and medical costs. PRIMARY OUTCOME PARAMETER: The number of catheter-related bloodstream infections and/or catheter-related thromboses and/or catheter-associated organ injuries related to the use of UVC/PICC was the primary outcome. CONCLUSION: Extending the UVC dwell time may significantly reduce the number of painful invasive procedures, with the potential to positively impact not only long-term pain perception but also important social competencies (attention, learning, and behavior). Thus, the "UVC-You Will See" study has the potential to substantially change current neonatal intensive care practice.

Patterns of volatile organic compounds in excrements of preterm neonates.

BACKGROUND: As neonates are susceptible for many diseases, establishing noninvasive diagnostic methods is desirable. We hypothesized that volatile organic compounds (VOCs) could be successfully measured in diaper samples. METHODS: We performed a feasibility study to investigate whether ambient air-independent headspace measurements of the VOC profiles of diapers from premature infants can be conducted using ion mobility spectrometer coupled with multi-capillary columns (B & S Analytik GmbH). RESULTS: We analysed 39 diapers filled with stool (n = 10) or urine (n = 20) respectively, using empty diapers as a control (n = 9). A total of 158 different VOCs were identified, and we classified the content of the diapers (urine or stool) according to their VOC profiles with a significance level of p < 0.05. CONCLUSIONS: We have developed a novel method to study headspace VOC profiles of biosamples using ion mobility spectrometry coupled with multi-capillary columns. Using this method, we have characterized the VOC profiles of stool and urine of preterm neonates. Future studies are warranted to characterize specific VOC profiles in infections and other diseases of the preterm neonate, thus establishing quick and noninvasive diagnostics in the routine care of the highly vulnerable preterm and term neonates.

Expression of TRAIL, IP-10, and CRP in children with suspected COVID-19 and real-life impact of a computational signature on clinical decision-making: a prospective cohort study.

PURPOSE: We evaluated the host-response marker score "BV" and its components TRAIL, IP-10, and CRP in SARS-CoV-2 positive children, and estimated the potential impact on clinical decision-making. METHODS: We prospectively analyzed levels of TRAIL, IP-10, CRP, and the BV score, in children with suspected COVID-19. Classification of infectious etiology was performed by an expert panel. We used a 5-point-questionnaire to evaluate the intention to treat with antibiotics before and after receiving test results. RESULTS: We screened 111 children, of whom 6 (5.4%) were positive for SARS-CoV-2. A total of 53 children were included for the exploratory analysis. Median age was 3.1 years (interquartile range [IQR] 1.3-4.3), and 54.7% (n = 29) were girls. A viral and a bacterial biomarker pattern was found in 27/53 (50.9%) and 15/53 (28.3%), respectively. BV scores differed between COVID-19, children with other viral infections, and children with bacterial infections (medians 29.5 vs. 9 vs. 66; p = 0.0006). Similarly, median TRAIL levels were different (65.5 vs. 110 vs. 78; p = 0.037). We found no differences in IP-10 levels (555 vs. 504 vs. 285; p = 0.22). We found a concordance between physicians' "unlikely intention to treat" children with a viral test result in most cases (n = 19/24, 79.2%). When physicians expressed a "likely intention to treat" (n = 15), BV test revealed 5 bacterial, viral, and equivocal scores each. Antibiotics were withheld in three cases (20%). Overall, 27/42 (64%) of pediatricians appraised the BV test positively, and considered it helpful in clinical practice. CONCLUSION: Host-response based categorization of infectious diseases might help to overcome diagnostic uncertainty, support clinical decision-making and reduce unnecessary antibiotic treatment.

Enteral Nutrition in Preterm Infants (2022): A Position Paper From the ESPGHAN Committee on Nutrition and Invited Experts.

OBJECTIVES: To review the current literature and develop consensus conclusions and recommendations on nutrient intakes and nutritional practice in preterm infants with birthweight <1800 g. METHODS: The European Society of Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) Committee of Nutrition (CoN) led a process that included CoN members and invited experts. Invited experts with specific expertise were chosen to represent as broad a geographical spread as possible. A list of topics was developed, and individual leads were assigned to topics along with other members, who reviewed the current literature. A single face-to-face meeting was held in February 2020. Provisional conclusions and recommendations were developed between 2020 and 2021, and these were voted on electronically by all members of the working group between 2021 and 2022. Where >90% consensus was not achieved, online discussion meetings were held, along with further voting until agreement was reached. RESULTS: In general, there is a lack of strong evidence for most nutrients and topics. The summary paper is supported by additional supplementary digital content that provide a fuller explanation of the literature and relevant physiology: introduction and overview; human milk reference data; intakes of water, protein, energy, lipid, carbohydrate, electrolytes, minerals, trace elements, water soluble vitamins, and fat soluble vitamins; feeding mode including mineral enteral feeding, feed advancement, management of gastric residuals, gastric tube placement and bolus or continuous feeding; growth; breastmilk buccal colostrum, donor human milk, and risks of cytomegalovirus infection; hydrolyzed protein and osmolality; supplemental bionutrients; and use of breastmilk fortifier. CONCLUSIONS: We provide updated ESPGHAN CoN consensus-based conclusions and recommendations on nutrient intakes and nutritional management for preterm infants.

Standardized Treatment and Diagnostic Approach to Reduce Disease burden in the early postoperative phase in children with congenital heart defects-STANDARD study: a pilot randomized controlled trial.

To explore the effect of a daily goal checklist on pediatric cardiac intensive care unit (PCICU) length of stay (LOS) after congenital heart surgery. This study is a prospective randomized single-center study. Group characteristics were as follows: STANDARD group: n = 30, 36.7% female, median age 0.9 years; control group: n = 33, 36.4% female, median age 1.1 years. Invasive ventilation time, STAT categories, mean vasoactive-inotropic score (VIS)24h, maximal (max.) VIS24h, mean VIS24-48h, max. VIS24-48h, VIS category, number of sedatives, analgesics, diuretics, number of deployed diagnostic modalities, morbidities, and mortality did not differ between both groups. Median PCICU LOS was 96.0 h (STANDARD group) versus 101.5 h (control group) (p = 0.63). In the overall cohort, univariate regression analysis identified age at surgery (b = -0.02), STAT category (b = 18.3), severity of CHD (b = 40.6), mean VIS24h (b = 3.5), max. VIS24h (b = 2.2), mean VIS24-48h (b = 6.5), and VIS category (b = 13.8) as significant parameters for prolonged PCICU LOS. In multivariate regression analysis, age at surgery (b = -0.2), severity of CHD (b = 44.0), and mean VIS24h (b = 6.7) were of significance. Within the STANDARD sub-group, univariate regression analysis determined STAT category (b = 32.3), severity of CHD (b = 70.0), mean VIS24h (b = 5.0), mean VIS24-48h (b = 5.9), number of defined goals (b = 2.6), number of achieved goals (b = 3.3), number of not achieved goals (b = 10.8), and number of unevaluated goals (b = 7.0) as significant parameters for prolonged PCICU LOS. Multivariate regression analysis identified the number of defined goals (b = 2.5) and the number of unevaluated goals (b = -3.0) to be significant parameters.   Conclusion: The structured realization and recording of daily goals is of advantage in patients following pediatric cardiac surgery by reducing PCICU LOS. What is known: • Communication errors are the most frequent reasons for adverse events in intensive care unit patients. • Improved communication can be achieved by discussion and documentation of the patients' goals during daily rounds. What is new: • In the overall cohort age at surgery, severity of congenital heart defect and mean vasoactive inotropic score within the first 24 hours had significant impact on pediatric cardiac intensive care unit (PCICU) length of stay (LOS). • In the intervention group, the number of defined goals and the number of unevaluated goals were significant parameters for prolonged PCICU LOS.

Inferior vena cava thrombosis-rope ladder sign.

Congenital heart disease comprises one of the largest groups of congenital defects, affecting approximately 1% of births. Advances in pre- and postoperative critical care treatment as well as surgery and interventional procedures have improved survival rates, but treatment and long-term care of children with complex congenital heart disease remains challenging, and is associated with a number of complications.Here, we report on a 17-month-old infant with congenital univentricular heart disease who devloped post-operatively inferior vena cava (IVC) thrombosis. IVC thrombosis was confirmed by a bedside contrast media study (X-ray) demonstrating collateral paravertebral circulation along the paravertebral sinuses bilaterally into the azygos and hemiazygos vein ("rope ladder sign"), with no contrast media detected in the IVC. The infant was subsequently started on aspirin and clopidogrel.

[Pseudotumor cerebri in children and adolescents at the Saarland University Medical Center: a retrospective study]. / Pseudotumor cerebri bei Kindern und Jugendlichen am Universitätsklinikum des Saarlandes: Eine retrospektive Studie.

Pseudotumor cerebri (PTC) is defined as a rare disease with a pathological increase in intracranial pressure of unknown origin. The aim of this retrospective study was to establish a uniform diagnostic and therapeutic protocol for children and adolescents for the Saarland University Medical Center. Data from 28 patients with pseudotumor cerebri aged 0-17 years in the period 2008-2018 were retrospectively collected and statistically analyzed. The purpose of this study was to generate a better understanding of the clinical entity of pseudotumor cerebri in children and adolescents. Distinctive features, such as pubertal or adolescent age, female gender and obesity could be highlighted. The data collected in this study were used to develop an in-house standard for the diagnosis and treatment of children and adolescents with pseudotumor cerebri.

[Assessment of the importance of neuropediatric diagnostics in the initial clarification of autism]. / Beurteilung des Stellenwertes der neuropädiatrischen Diagnostik im Rahmen der initialen Autismusabklärung.

BACKGROUND: The diagnostics of autism spectrum disorder is complex due to missing biological markers and numerous comorbidities. The aim was to assess the role of neuropediatric diagnostics and to develop a standard operating procedure for a targeted assessment. METHOD: All patients presenting to the neuropediatric outpatient clinic at Saarland University Hospital between April 2014 and December 2017 with ICD code F84 pervasive developmental disorders were included. RESULTS: A total of 82 patients were included (male 78%, female 22%; mean age 5.9 ± 2.9 years, range 2-16 years). The most frequent examination was electroencephalography (EEG) (74/82; 90.2%) with pathological findings in 33.8% (25/74). Based on the history and/or EEG epilepsy was diagnosed in 19.5% (16/82). Magnetic resonance imaging (MRI) was performed in 49/82 (59.8%) patients, 22/49 (44.9%) showed at least 1 cerebral abnormality and definite pathologies could be detected in 63.6% (14/22). A metabolic diagnostic work-up was performed in 44/82 (53.7%) cases and in 5/44 (11.4%) it resulted in a diagnosis or suspicion of a metabolic disease. Genetic testing results were available in 29/82 (35.4%) children and 12/29 (41.4%) showed abnormal results. Delay in motor development was more frequently associated with comorbidities, EEG abnormalities, epilepsy and abnormalities in metabolic and genetic testing. CONCLUSION: Neuropediatric examination in cases of suspected autism should include a detailed history, a thorough neurological examination and an EEG. An MRI, comprehensive metabolic and genetic testing are only recommended if clinically indicated.

Something is up in the air: pneumothorax and pneumopericardium in a 29-week preterm infant.

This report highlights the early and unusual detection of a pneumopericardium by echocardiography prior to potential development of cardiocirculatory compromise. It is important to consider pneumopericardium into the differential diagnosis when difficulties arise in the visualization of the heart by conventional echocardiography. Pneumopericardium is associated with a high mortality rate and may be effectively treated by immediate insertion of a pericardial catheter.

Umbilical venous catheter- and peripherally inserted central catheter-associated complications in preterm infants with birth weight < 1250 g : Results from a survey in Austria and Germany.

BACKGROUND AND OBJECTIVE: Umbilical venous catheters (UVC) and peripherally inserted central catheters (PICC) are commonly used in preterm infants but have been associated with a number of serious complications. We performed a survey in Austria and Germany to assess the use of UVCs and PICCs in preterm infants with a birth weight < 1250 g and associated rates of catheter-related adverse events. METHODS: Electronic survey of participating centers of the NeoVitaA trial. Main outcome parameter was the reported rates of UVC- and PICC-associated complications (infection, thrombosis, emboli, organ injury, arrhythmia, dislocation, miscellaneous). RESULTS: In total, 20 neonatal intensive care units (NICU) providing maximal intensive care in Austria and Germany (level I) were contacted, with a senior neonatologist response rate of 12/20 (60%). The reported rates for UVC with a dwell time of 1-10 days were bacterial infection: 4.2 ± 3.4% (range 0-10%); thrombosis: 7.3 ± 7.1% (0-20%); emboli: 0.9 ± 2.0% (0-5%); organ injury: 1.1 ± 1.9% (0-5%); cardiac arrhythmia: 2.2 ± 2.5% (0-5%); and dislocation: 5.4 ± 8.7% (0-30%); and for PICCs with a dwell time of 1-14 days bacterial infection: 15.0 ± 3.4% (range 2.5-30%); thrombosis; 4.3 ± 3.5% (0-10%); emboli: 0.8 ± 1.6% (0-5%); organ injury: 1.5 ± 2.3% (0-5%); cardiac arrhythmia: 1.5 ± 2.3% (0-5%), and dislocation: 8.5 ± 4.6% (0-30%). CONCLUSION: The catheter-related complication rates reported in this survey differed between UVCs and PICCs and were higher than those reported in the literature. To generate more reliable data on this clinically important issue, we plan to perform a large prospective multicenter randomized controlled trial investigating the non-inferiority of a prolonged UVC dwell time (up to 10 days) against the early change (up to 5 days) to a PICC.

Is There a Role for Cerebral Ultrasonography in Near-Term/Term Neonates Following Assisted Vaginal Delivery? A Prospective, Single-Center Study.

AIM: To evaluate the role of cerebral ultrasonography studies (CUSS) in detecting intracerebral and cranial pathologies (hemorrhages, ischemia, skull fractures) in near-term and term neonates following assisted vaginal delivery. PATIENTS AND METHODS: Prospective single-center study (11/2017-11/2018) at the University Children's Hospital of Saarland, Homburg, Germany including newborns with a gestational age ≥ 36 weeks born by assisted vaginal delivery. In all newborns, a standardized CUSS was performed within the first three days of life prior to discharge. RESULTS: 200 neonates (43.0 % female, 57.0 % male; gestational age 39.6 ±â€Š1.3 weeks) were included in this study (birth weight 3345.6 ±â€Š450.6 g, body length 51.7 ±â€Š2.5 cm, head circumference 35.0 ±â€Š1.5 cm). 67 (33.5 %) neonates had minor external injuries of the scalp. 5 children showed clinical neurologic abnormalities: 4 (2.0 %) seizures and 1 facial palsy (0.5 %). In 34 (17.0 %) patients, minor incidental intracranial abnormalities unrelated to mode of delivery were detected on CUSS. No intracerebral, cranial pathologies or skull fractures were seen on routine CUSS. CONCLUSION: Routine CUSS in newborns after assisted vaginal delivery did not yield clinically relevant results in our cohort. Clinical observation and selective CUSS in symptomatic newborns might be more efficient than routine CUSS.

[Pott's Puffy Tumor: a need for interdisciplinary diagnosis and treatment. German Version]. / Pott-Puffy-Tumor: die Notwendigkeit einer interdisziplinären Diagnostik und Behandlung.

Pott's puffy tumor (PPT) is an infection of the frontal sinus with subperiosteal and intracranial abscess formation and one of the rare entities in pediatrics. We present a series of four cases of PPT that occurred in two children (6 and 9 years) and in two young adults (17 and 19 years). All patients were treated by an interdisciplinary team of pediatric, neurosurgical, ENT, radiological, and neuroradiological specialists. Antibiotic treatment was combined with single endoscopic surgery in one case and combined endoscopic sinus surgery with an open transcranial approach to drain intracranial abscess formation in three cases. It is important to be aware that PPT occurs in children with the finding of intracranial abscess formation. Therefore, a close interdisciplinary cooperation for successful treatment is needed in this rare disease.

Hydrops fetalis with isolated massive ascites in a preterm neonate with rhesus disease.

Significant progress in prenatal care has decreased the incidence of rhesus incompatibility, which may result in hemolytic disease of the fetus and newborn (HDFN). This case report describes an unusual presentation of HDFN in a preterm infant delivered by caesarean section with isolated massive abdominal fluid collection as the leading clinical sign in addition to severe anemia. The immediate drainage of ascites provided transient clinical stabilization with improved pulmonary function in the delivery suite. After admission to the neonatal intensive care unit (NICU), HDFN treatment was initiated. This case report shows the importance of adequately trained staff including neonatologists, pediatricians and NICU nurses in the delivery suite to provide neonatal intensive care for HDFN.

Soft tissue infection as a rare cause of neonatal sepsis.

Umbilical venous and peripherally inserted central venous catheters are often used in preterm infants, but complications include late-onset catheter-associated infections. Conversely, other sites of infection have to be taken into account in the case of clinical deterioration. In this Image in Science and Medicine paper, we report on a preterm infant with a rare cause of neonatal sepsis.

Distended abdomen due to a pseudocyst around a ventriculoperitoneal shunt.

Described herein is a case of distended abdomen in a 4-year-old boy with a ventriculoperitoneal (VP) shunt due to bilateral intraventricular hemorrhage following premature birth. Physical examination and laboratory tests revealed tenderness in the lower quadrants, with mild leukocytosis and normal C­reactive protein levels. X­ray demonstrated an intact VP shunt catheter but cranial displacement of the large intestine. Ultrasonography confirmed a large pseudocyst around the VP shunt, with extension from the symphysis to the sternum. The distal part of the VP shunt was surgically revised and 2.5 l of cerebrospinal fluid were evacuated. The boy made a full clinical recovery. Conventional X­rays, routinely used to confirm or exclude VP shunt continuity, may provide important clues regarding to the etiology of VP shunt dysfunction.

Patients with Pulmonary Metastases from Head and Neck Cancer Benefit from Pulmonary Metastasectomy, A Systematic Review.

Background and Objectives: The incidence of distant metastases in patients with head and neck cancer (HNC) is approximately 10%. Pulmonary metastases are the most frequent distant location, with an incidence of 70-85%. The standard treatment options are chemo-, immuno- and radiotherapy. Despite a benefit for long-term survival for patients with isolated pulmonary metastases, pulmonary metastasectomy (PM) is not the treatment of choice. Furthermore, many otorhinolaryngologists are not sufficiently familiar with the concept of PM. This work reviews the recent studies of pulmonary metastatic HNC and the results after pulmonary metastasectomy. Materials and Methods: PubMed, Medline, Embase, and the Cochrane library were checked for the case series' of patients undergoing metastasectomy with pulmonary metastases published since 1 January 2000. Results: We included the data of 15 studies of patients undergoing PM. The 5-year survival rates varied from 21% to 59%, with median survival from 10 to 77 months after PM. We could not identify one specific prognostic factor for long-term survival after surgery. However, at least most studies stated that PM should be planned if a complete (R0) resection is possible. Conclusions: PM showed reliable results and is supposedly the treatment of choice for patients with isolated pulmonary metastases. Patients not suitable for surgery may benefit from other non-surgical therapy. Every HNC patient with pulmonary metastases should be discussed in the multidisciplinary tumor board to optimize the therapy and the outcome.

Different Effects of Two Protocols for Pre-Procedural Analgosedation on Vital Signs in Neonates during and after Endotracheal Intubation.

BACKGROUND: Analgosedation is often used for endotracheal intubation in neonates, but no consensus exists on the optimal pre-procedural medication. AIMS: To compare the time to intubation and vital signs during and after intubation in 2 NICUs using different premedication protocols. METHODS: Prospective observational study in 2 tertiary NICUs, comparing fentanyl and optional vecuronium for elective neonatal endotracheal intubation (NICU-1) with atropine, morphine, midazolam and optional pancuronium (NICU-2). Primary endpoints were: time to intubate and number of intubation attempts; secondary endpoints were: deviations of heart rate, oxygen saturation and blood pressure from baseline until 20 min post intubation. RESULTS: 45 and 30 intubations were analyzed in NICU-1 and NICU-2. Time to intubation was longer in NICU-1 (7 min) than in NICU-2 (4 min; p=0.029), but the mean number of intubation attempts did not differ significantly. Bradycardias (34 vs. 1, p<0.001) and hypoxemias (136 vs. 48, p<0.001) were more frequent in NICU-1, and tachycardias (59 vs. 72, p<0.001) more frequent in NICU-2. Mean arterial blood pressure (MAP) increased in NICU-1 (+6.18 mmHg) and decreased in NICU-2 (-5.83 mmHg), whereas mean heart rates (HR) decreased in NICU-1 (-19.29 bpm) and increased in NICU-2 (+15.93 bpm). MAP and HR returned to baseline 6-10 min after intubation in NICU-1 and after 11-15 min and 16-20 min in NICU-2, respectively. CONCLUSIONS: The two protocols yielded significant differences in the time to intubation and in the extent and duration of physiologic changes during and post-intubation. Short acting drugs should be preferred and vital signs should be closely monitored at least 20 min post intubation. More studies are required to identify analgosedation protocols that minimize potentially harmful events during endotracheal intubation.
