Abstract
PURPOSE Ultrasound-guided peripherally inserted central catheters (PICCs) are increasingly used in children, though their insertion may be limited by the small caliber of the deep veins of the arm. Previous studies have suggested to use age or weight as a guide to the feasibility of PICC insertion. We have planned an observational study with the purpose of identifying the actual feasibility of PICC insertion based on the ultrasound evaluation of the deep veins of the arm in groups of children of different weight range. METHODS We have studied 252 children weighing between 2.5 and 20 kg, divided in five different groups (group 1: 2.5-4 kg; group 2: 4.1-7 kg; group 3: 7.1-10 kg; group 4: 10.1-15 kg; group 5: 15.1-20 kg): the caliber of brachial vein, basilic vein, and cephalic vein at mid-upper arm + the caliber of the axillary vein at the axilla were measured by ultrasound scan. RESULTS Veins of caliber >3 mm (appropriate for insertion of a 3 Fr non-tunneled PICC) were found at mid-upper arm in no child of group 1 or 2, in 13% of group 3, in 28% of group 4, and in 54% of group 5. An axillary vein >3 mm (appropriate for insertion of a 3 Fr tunneled PICC) were found in 5.8% of group 1, 30.6% of group 2, 67% of group 3, 82% of group 4, and 94% of group 5. CONCLUSIONS The age and the weight of the child have a small role in predicting the caliber of the veins of the arm. Veins should be measured case by case through a proper and systematic ultrasound evaluation; however, the clinician can expect that insertion of a 3 Fr PICC may be feasible in one third of children weighing between 4 and 7 kg, and in most children weighing more than 7 kg, especially if adopting the tunneling technique.

Modified fluid gelatin 4% for perioperative volume replacement in pediatric patients (GPS): Results of a European prospective noninterventional multicenter study. Paediatr Anaesth 2022; 32:825-833. [PMID: 35426196 DOI: 10.1111/pan.14459] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Revised: 04/01/2022] [Accepted: 04/10/2022] [Indexed: 11/30/2022]
Abstract
INTRODUCTION Modified fluid gelatin 4% is approved for use in children, but there is still a surprising lack of clinical studies including large numbers of pediatric patients. Therefore, we performed a European prospective noninterventional multicenter study to evaluate the use of a modified fluid gelatin 4% in saline (sal-GEL) or an acetate-containing balanced electrolyte solution (bal-GEL) in children undergoing major pediatric surgery. AIMS The primary aim was to assess the indications and dosing of modified fluid gelatin, and the secondary aim was to assess the safety and efficacy, focusing, in particular, on routinely collected clinical parameters. METHODS Children aged up to 12 years with ASA risk scores of I-III receiving sal-GEL or bal-GEL were followed perioperatively. Demographic data, surgical procedures performed, anesthesia, hemodynamic and laboratory data, adverse events, and adverse drug reactions were documented using a standardized case report form. RESULTS 601 children that were investigated at 13 European pediatric centers from May 2015 to March 2020 (sal-GEL 20.1%, bal-GEL 79.9%; mean age 29.1 ± 38.6 (range 0-144) months; body weight 12.1 ± 10.5 (1.4-70) kg) were included in the analysis. The most frequent indications for GEL infusion were hemodynamic instability without bleeding (76.0%), crystalloids alone not being sufficient for hemodynamic stabilization (55.7%), replacement of preoperative deficit (26.0%), and significant bleeding (13.0%). Mean infused GEL volume was 13.0 ± 5.3 (2.4-37.5) ml kg-1 . The total dose was affected by age, with higher doses in younger patients. After gelatin infusion, mean arterial pressure increased (mean change 8.5 ± 7.3 [95% CI: 8 to 9.1] mmHg), and the hemoglobin concentrations decreased significantly (mean change -1.1 ± 1.8 [95% CI: -1.2 to -0.9] g·dL-1 ). Acid-base parameters were more stable with bal-GEL. No serious adverse drug reactions directly related to gelatin (i.e., anaphylactoid reaction, clotting disorders, and renal failure) were observed. CONCLUSION Moderate doses up to 20 ml kg-1 of modified fluid gelatin were infused most frequently to improve hemodynamic stability in children undergoing major pediatric surgery. The acid-base balance was more stable when gelatin in a balanced electrolyte solution was used instead of saline. No serious adverse drug reactions associated with gelatin were observed.

Abstract
BACKGROUND Subcutaneously anchored securement devices (or subcutaneous engineered securement devices) have been introduced recently into the clinical practice, but the number of published studies is still scarce. The Italian Group of Long-Term Central Venous Access Devices (GAVeCeLT)-in collaboration with WoCoVA (World Congress on Vascular Access)-has developed a Consensus about the effectiveness, safety, and cost-effectiveness of such devices. METHODS After the definition of a panel of experts, a systematic collection and review of the literature on subcutaneously anchored securement devices was performed. The panel has been divided in two working groups, one focusing on adult patients and the other on children and neonates. RESULTS Although the quality of evidence is generally poor, since it is based mainly on non-controlled prospective studies, the panel has concluded that subcutaneously anchored securement devices are overall effective in reducing the risk of dislodgment and they appear to be safe in all categories of patients, being associated only with rare and negligible local adverse effects; cost-effectiveness is demonstrated-or highly likely-in specific populations of patients with long-term venous access and/or at high risk of dislodgment. CONCLUSION Subcutaneously anchored securement is a very promising strategy for avoiding dislodgment. Further studies are warranted, in particular for the purpose of defining (a) the best management of the anchoring device so to avoid local problems, (b) the patient populations in which it may be considered highly cost-effective and even mandatory, (c) the possible benefit in terms of reduction of other catheter-related complications such as venous thrombosis and/or infection, and-last but not least-(d) their impact on the workload and stress level of nurses taking care of the devices.

Total oesophago-gastric dissociation in neurologically impaired children: Laparoscopic vs robotic approach. Int J Med Robot 2019; 16:e2048. [PMID: 31797517 DOI: 10.1002/rcs.2048] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2019] [Revised: 09/24/2019] [Accepted: 10/07/2019] [Indexed: 12/30/2022]
Abstract
PURPOSE To evaluate and compare the feasibility and short-term results of laparoscopic and robotic total oesophago-gastric dissociation (TOGD) with a Roux-en-Y oesophago-jejunostomy. Minimal invasive surgery has multiple advantages in neurologically impaired patients. Robotic approach has overcome disadvantages linked to laparoscopy, in particular, referring to the surgeon fatigue. METHODS A retrospective study comparing five laparoscopic and five robotic TOGD was conducted between February and October 2016 in Giannina Gaslini Children's Hospital and Section of Pediatric Surgery of Siena. Neurologically impaired children scheduled for TOGD were included. Age, sex, weight, symptomatology, presence of epilepsy, and preoperative X-ray contrast were considered. Operative time, hospital stay, postoperative complications, redo surgery, nutrition rehabilitation, and X-ray contrast study after 5 days and after 1 month from the intervention were recorded. RESULTS In our series, there were no intraoperative complications, no conversions to open surgery, and no vagal lesions. In two of five robotic cases, a pyloroplasty was necessary. The median operative time was statistically longer in the robotic group. One dehiscence in the robotic group was recorded, and no dumping episodes occurred. No statistical differences in terms of complications were detected. CONCLUSION TOGD is feasible both with laparoscopic and robotic-assisted surgery with similar results. Robotic approach is considered feasible. At the same time, high laparoscopic skills allow to reach the same results as robotic approach with shorter operative time.

Abstract
BACKGROUND Ultrasound-guided (USG) cannulation of the brachiocephalic vein (BCV) is gaining worldwide consensus for central venous access in children. This study reports a 20-month experience with this approach in children. METHODS All patients who underwent percutaneous USG central venous catheter (CVC) positioning in the BCV between August 2013 and March 2015 have been included. Devices inserted during this period were open-ended, either single or double-lumen tunneled CVC. Our series was divided into three consecutive study periods in order to determine the relative incidence of repositioning and complications. RESULTS During the study period, a total of 95 patients underwent 109 CVC insertions in the BCV. The median length of CVC duration was 230 days for a total of 23,212 catheter days. No major intraoperative complications occurred. Overall rate of CVC-related postoperative complications requiring repositioning or precocious removal was 0.90 per 1,000 catheter days and involved 21 CVC (19%, 95% confidence interval 13-28). These included 18 dislodgments, two infections, and one malfunction. Double-lumen CVCs represented the only significant risk factor for complications (52% complications-three per 1,000 catheter days). CONCLUSION USG supraclavicular cannulation of the BCV represents a safe approach for central line placement in children. It proved to be versatile, as it can be used in premature infants as well as in adolescents. Provided it is adopted by operators experienced in USG cannulation, we strongly suggest to resort to this approach as a first-line choice in children undergoing tunnelled central line placement for long-lasting therapy.

Congenital Lung Malformations: Shifting from Open to Thoracoscopic Surgery. Pediatr Neonatol 2016; 57:463-466.

Abstract
BACKGROUND Over the years the need for surgical treatment, timing of intervention, and the type of surgical approach have been discussed, but the treatment of congenital lung malformations remains controversial. The aim of this study was to compare the thoracotomy approach with the thoracoscopic technique by evaluating different surgical outcomes (duration of surgery, postoperative hospital stay, and complications). METHODS All patients operated from January 2011 to March 2015 for suspected congenital cystic lung were included in the study. Patients treated for congenital lobar emphysema and tracheobronchial neoplasms were excluded from the study. RESULTS In the analyzed period, 31 asymptomatic patients were treated: 18 lung resections were performed with thoracotomy (Group A) and 13 with the thoracoscopic approach (Group B). No significant differences were observed between the age and weight at surgery, length of the procedures, complications, and the need for postoperative intensive care between the two groups. The postoperative hospital stay in Group A was twice that for Group 2 (p = 0.0009). CONCLUSION Comparing thoracoscopic surgery with the traditional open approach, we confirmed the superiority of minimally invasive treatment in terms of postoperative hospital stay. Common technical recommendations can help pediatric centers to develop the thoracoscopic approach for the treatment of congenital pulmonary malformations.

Abstract
Mucolipidosis type IV (MLIV) is a very rare disorder of late endosome/lysosome transport, characterized by neurodevelopmental abnormalities and progressive visual impairment owing to corneal clouding and retinal dystrophy. Greater than 70 % of MLIV patients are of Ashkenazi Jewish ancestry. Here we report a novel MCOLN1double mutant allele [c.395_397delCTG;c.468_474dupTTGGACC] which introduces a premature stop codon [p.Ala132del; p.Asn159LeufsX27] leading to almost complete abrogation of the region coding mucolipin-1, a member of the transient receptor potential (TRP) cation channel family. The genomic lesion was identified in homozygous state, in a non-Jewish Italian MLIV patient, who also presented abnormal serum gastrin levels. Conventional and advanced MRI sequences, including diffusion tensor imaging and tractography, were used for the assessment of white matter involvement in the patient.

Abstract
PURPOSES The aims of this study are to describe a cohort of head-injured pediatric patients, focusing on current practice for intracranial pressure (ICP) monitoring and treatment and to verify the relationship between clinical and radiological parameters and the six-month outcome in a multivariable statistical model. METHODS A retrospective review was done of a prospectively collected database considering patients younger than 19 years admitted to three neuro-intensive care units (ICU). Patients were divided into four age groups: 0-5 (infant), 6-12 (children), 13-16 (pre-adolescent) and 17-18 years (adolescent). The ICP and cerebral perfusion pressure (CPP) were analyzed calculating average data and values exceeding thresholds for more than 5 min. Outcome was assessed 6 months after trauma using the Glasgow Outcome Score. RESULTS There were 199 patients, 155 male, included. Sixty percent had extracranial injuries. Pupils were abnormal in 38 %. Emergency evacuation of intracranial hematomas was necessary in 81 cases. The ICP was monitored in 117 patients; in 87 cases ICP was higher than 20 mmHg, with no differences among age groups. All but six patients received therapy to prevent raised ICP; barbiturates, deep hyperventilation or surgical decompression were used in 31 cases. At 6 months, mortality was 21 % and favorable outcome was achieved by 72 %. Significant predictors of outcome in the multivariable model were the Glasgow Coma Scale (GCS) motor score, pupils and ICP. CONCLUSIONS Pediatric head injury is associated with a high incidence of intracranial hypertension. Early surgical treatment and intensive care may achieve favorable outcome in the majority of cases.

Abstract
BACKGROUND Eighteen patients with severe and refractory Tourette Syndrome underwent bilateral thalamic deep brain stimulation. The surgical procedures and stimulation processes of the cohort were reported in 2008; the 2 year follow-up was reported in 2009. The aim of the research is the assessment of long-term outcome (5-6 years) on tics, obsessional behaviours, anxiety, mood, and on the overall general health of the patients and their general satisfaction. METHOD In this study, all 18 of the original patients will be discussed, pre- and post-DBS, according to our protocol using standardized objective schedules, as well as the clinical impressions of both clinicians and patients. As there were no substantial nor statistical differences on measures of cognitive functioning between pre-DBS and 2 year follow-up, we decided not to continue this aspect of the formal assessment, particularly as there were also no clinical indications. RESULTS At 5-6 year follow-up, there was a significant reduction in tic severity (p < 0.001), and significant improvements in obsessive compulsive behaviours (p = 0.003), anxiety (p < 0.001) and depressive (p < 0.001) symptoms. Patients, in general, required less medication for tics, co-morbid conditions and/or co-existent psychopathologies. The long-term outcome/satisfaction were not unanimous between patients and the medical team. CONCLUSIONS At long-term follow-up, DBS was very successful in terms of a significant improvement in tics and also a significant reduction in the potentially disabling symptoms of obsessionality, anxiety and depression. However, compared with our more positive overall results at 2 years, these later results demonstrate long-term difficulties as follows: non-compliance, long-term complications , and the differences in the opinions between the (a) medical, (b) the surgical teams and (c) the post-DBS patients as to their outcome/satisfaction with the procedures. Our experience highlights the need for controlled studies, for long-term follow up, and the need to improve the selection of patients for DBS.

Abstract
Traumatic brain injury (TBI) in children is frequent, sometimes lethal, and may have life-long consequences in survivors. Prevention at school and in sports, including both kids and families, is of paramount importance. Scarce data are available in terms of epidemiology, physiopathology, management and prognosis. This non-systematic review suggests that rational organization of rescue and transport to designated hospitals, linked with early diagnosis/removal of surgical masses and comprehensive monitoring and intensive care, offer the best chances for reducing mortality and morbidity in severe cases. After the acute phase rehabilitation and families play a fundamental role.

Abstract
OBJECTIVE To quantify the occurrence of high intracranial pressure (HICP) refractory to conventional medical therapy after traumatic brain injury (TBI) and to describe the use of more aggressive therapies (profound hyperventilation, barbiturates, decompressive craniectomy). DESIGN Prospective study of 407 consecutive TBI patients SETTING Three neurosurgical intensive care units (ICU). MEASUREMENTS AND RESULTS Intracranial pressure (ICP) was studied during the first week after TBI; 153 patients had at least 1 day of ICP>20 mmHg. Early surgery was necessary for 221 cases, and standard medical therapy [sedation, mannitol, cerebrospinal fluid (CSF) withdrawal, PaCO2 30-35 mmHg] was used in 135 patients. Reinforced treatment (PaCO2 25-29 mmHg, induced arterial hypertension, muscle relaxants) was used in 179 cases (44%), and second-tier therapies in 80 (20%). Surgical decompression and/or barbiturates were used in 28 of 407 cases (7%). Six-month outcome was recorded in 367 cases using the Glasgow outcome scale (GOS). The outcome was favorable (good recovery or moderate disability) in 195 cases (53%) and unfavorable (all the other categories) in 172 (47%). HICP was associated with worse outcome. Outcome for cases who had received second-tier therapies was significantly worse (43% favorable at 6 months, p=0.03). CONCLUSIONS HICP is frequent and is associated with worse outcome. ICP was controlled by early surgery and first-tier therapies in the majority of cases. Profound hyperventilation, surgical decompression and barbiturates were used in various combinations in a minority of cases. The indications for surgical decompression and/or barbiturates seem restricted to less than 10% of severe TBI.
