Background Hand–eye coordination and ergonomics are important for the success of delicate ultrasound-guided medical procedures. These can be improved using smart glasses (head-mounted display) by decreasing the head movement on the ultrasound screen. The hypothesis was that the smart glasses could improve the success rate of ultrasound-guided pediatric radial arterial catheterization. Methods This prospective, single-blinded, randomized controlled, single-center study enrolled pediatric patients (n = 116, age less than 2 yr) requiring radial artery cannulation during general anesthesia. The participants were randomized into the ultrasound screen group (control) or the smart glasses group. After inducing general anesthesia, ultrasound-guided radial artery catheterization was performed. The primary outcome was the first-attempt success rate. The secondary outcomes included the first-attempt procedure time, the overall complication rate, and operators’ ergonomic satisfaction (5-point scale). Results In total, 116 children were included in the analysis. The smart glasses group had a higher first-attempt success rate than the control group (87.9% [51/58] vs. 72.4% [42/58]; P = 0.036; odds ratio, 2.78; 95% CI, 1.04 to 7.4; absolute risk reduction, –15.5%; 95% CI, −29.8 to −12.8%). The smart glasses group had a shorter first-attempt procedure time (median, 33 s; interquartile range, 23 to 47 s; range, 10 to 141 s) than the control group (median, 43 s; interquartile range, 31 to 67 s; range, 17 to 248 s; P = 0.007). The overall complication rate was lower in the smart glasses group than in the control group (5.2% [3/58] vs. 29.3% [17/58]; P = 0.001; odds ratio, 0.132; 95% CI, 0.036 to 0.48; absolute risk reduction, 24.1%; 95% CI, 11.1 to 37.2%). The proportion of positive ergonomic satisfaction (4 = good or 5 = best) was higher in the smart glasses group than in the control group (65.5% [38/58] vs. 20.7% [12/58]; P <0.001; odds ratio, 7.3; 95% CI, 3.16 to 16.8; absolute risk reduction, –44.8%; 95% CI, –60.9% to –28.8%). Conclusions Smart glasses-assisted ultrasound-guided radial artery catheterization improved the first-attempt success rate and ergonomic satisfaction while reducing the first-attempt procedure time and overall complication rates in small pediatric patients.

Artery Cannulation

Background Pediatric radial artery cannulation is challenging because of the small vessel size. Nitroglycerin is a potent vasodilator and facilitates radial artery cannulation by increasing the internal diameter and preventing the vasospasm in adult patients. The authors hypothesize that subcutaneous nitroglycerin injection will improve the success rate of pediatric radial artery cannulation. Methods This double-blind, randomized, controlled, single-center study enrolled pediatric patients (n = 113, age less than 2 yr) requiring radial artery cannulation during general anesthesia. The participants were randomized into the nitroglycerin group (n = 57) or control group (n = 56). After inducing general anesthesia, nitroglycerin solution (5 μg/kg in 0.5 ml), or normal saline (0.5 ml) was subcutaneously injected above the chosen radial artery over 10 s with ultrasound guidance. Three minutes later, the ultrasound-guided radial artery cannulation was performed. Radial artery diameter was measured before and after the subcutaneous injection and after cannulation. The primary outcome was the first-attempt successful cannulation rate. The secondary outcomes included the diameter of the radial artery and the overall complication rate including hematoma and vasospasm. Results A total of 113 children were included in the analysis. The nitroglycerin group had a higher first-attempt success rate than the control group (91.2% [52 of 57] vs. 66.1% [37 of 56]; P = 0.002; odds ratio, 5.3; 95% CI, 1.83 to 15.6; absolute risk reduction, –25.2%; 95% CI, –39.6 to –10.7%). Subcutaneous nitroglycerin injection increased the diameter of the radial artery greater than normal saline (25.0 ± 19.5% vs. 1.9 ± 13.1%; 95% CI of mean difference, 16.9 to 29.3%; P < 0.001). Overall complication rate was lower in the nitroglycerin group than in the control group (3.5% [2 of 57] vs. 31.2% [18 of 56]; P = 0.001; odds ratio, 0.077; 95% CI, 0.017 to 0.350; absolute risk reduction, 28.6%; 95% CI, 15.5 to 41.8%). Conclusions Subcutaneous nitroglycerin injection before radial artery cannulation improved the first-attempt success rate and reduced the overall complication rates in pediatric patients.

AbstractBackgroundA low first-pass success rate of radial artery cannulation was obtained when using the conventional palpation technique(C-PT) or ultrasound-guided techniques, we therefore evaluate the effect of a modified long-axis in-plane ultrasound technique (M-LAINUT) in guiding radial artery cannulation in adults.MethodsWe conducted a prospective, randomized and controlled clinical trial of 288 patients undergoing radial artery cannulation. Patients were randomized 1:1 to M-LAINUT or C-PT group at fujian medical university union hospital between 2017 and 2018. Radial artery cannulation was performed by three anesthesiologists with different experience. The outcome was the first and total radial artery cannulation success rates, the number of attempts and the cannulation time.Results285 patients were statistically analyzed. The success rate of first attempt was 91.6% in the M-LAINUT group (n=143) and 57.7% in the C-PT group (n=142; P<0.001) (odds ratio, 7.9; 95% confidence interval, 4.0-15.7). The total success rate (≤5 min and ≤3 attempts) in the M-LAINUT group was 97.9%, compared to 84.5% in the palpation group (p <0.001) (odds ratio, 8.5; 95% confidence interval, 2.5-29.2). The total cannulation time was shorter and the number of attempts was fewer in the M-LAINUT group than that in the C-PT group (p <0. 05).ConclusionModified long-axis in-plane ultrasound-guided radial artery cannulation can increase the first and total radial artery cannulation success rates, reduce the number of attempts and shorten the total cannulation time in adults.

Aberrant Regeneration

Frey's syndrome was first described by Lucia Frey, a Polish neurologist in 1923. It is well accepted that it involves injury to the branches of the auriculotemporal nerve with subsequent aberrant regeneration. Due to this abnormal communication, the skin glands and vessels are always stimulated at the same time as eating and mastication, which results in symptoms such as flushing and sweating. The incidence of Frey's syndrome in the literature has been variously described from 6 to 96 per cent. We analyzed the chart of 18 patients who had parotidectomy from March 2002 to December 2009. All procedures were performed by a single surgeon at the same facility. A total of 16 superficial and three total parotidectomies were done; one patient had bilateral parotidectomy. Oxidized regenerated cellulose (Interceed) was used after 10 surgeries (study group) and no adjuvant was used after nine surgeries (control group). All of the surgeries were done using similar technique. All the patients were followed-up with for a period of about 6 months postoperatively. The absolute risk reduction associated with the placement of an Interceed was 11 per cent. The small number of cases (n = 19) and an empty cell limits statistical analysis (a Fisher's exact test revealed a P value of 0.44). Clearly the low number of procedures restricted the power to test these differences. The development of Frey's syndrome is a very disabling but under-reported complication. The placement of a temporary barrier like Interceed may help in the prevention of Frey's syndrome without increasing any complications.

Objective This prospective randomized controlled study aimed to compare the ultrasound-guided (USG) technique with the standard single-wall puncture technique for epicutaneo-caval catheter (ECC) placement in neonates. Study Design A total of 100 neonates were included in this study. All enrolled neonates were randomly divided into two groups (n = 50): the USG group and the control group. The control group underwent standard single-wall puncture for ECC placement procedures, and the USG group underwent USG ECC placement procedures. Results The first attempt success rates (62 vs. 38%; p = 0.016) and the total success rates (92 vs. 74%; p = 0.017) were higher in the USG group than in the control group. The procedure time was shorter in the USG group than in the control group: 351.43 (112.95) versus 739.78 seconds (369.13), p < 0.001. The incidence of adverse events was not significantly different between the two groups. Conclusion Compared with the standard single-wall puncture method, USG cannulation is superior for neonatal ECC placement, with a higher success rate, and decreases the total procedural time.

Early experience with ultrasound guided distal trans-radial access in the anatomical snuffbox in coronary angiography and intervention. Objective: We aimed to demonstrate the feasibility and safety of the ultrasound guided distal trans-radial coronary angiography and intervention. Methods: Patients assigned to one operator program underwent diagnostic or procedural intervention through distal trans-radial approach in the anatomical snuffbox between January 2018 and May 2018. All of patients had palpable artery in their distal radial artery. The operator did the coronary procedure via distal radial access at anatomical snuffbox. When the pulse was weak or the target artery was very small, the operator punctured under ultrasound guidance (V-scan with dual probe, GE heathcare, USA) Results: 56 patients were enrolled. Mean age of patients was 65.1 years old and 68% were male. About 70% of patients were presented with stable angina feature. In diagnostic procedure, 4F (3, 5.6%) or 5F (29, 54.7%) sheath was used and we did coronary intervention via 6F (21, 39.6%) Sheath. Ultrasound guided puncture was done for 33 patients (58.9%). Overall Success rate of distal trans-radial angiography and intervention was 94.6% (3 failed cases). Success rate of ultrasound guided procedure was 97% (only 1 failed case). Left distal radial puncture was done for 18 patients (33.9%). 16% of patients had chronic kidney disease, especially end stage renal disease (11%) to preserve radial artery which was potential candidate of arteriovenous fistulae for dialysis. There was no BARC type 2-5 bleeding in hospital stay and follow up at out-patient clinic. Conclusion: Ultra sound guided distal radial approach is feasible and safe as a good alternative technique for coronary angiography and interventions.

Background: The etiology for recurrent patellar dislocations in children with patellofemoral instability (PFI) is not always apparent. Radiographic and other imaging measures help guide the clinician. However, the imaging parameters for pathologic pediatric PFI and the significance of these measures based on severity are not clearly defined. This study compares common imaging measures for PFI in a non-pathologic and known patellar dislocation pediatric population and determines the likelihood of symptoms based on the severity of each individual measure. Methods: An IRB-approved retrospective review of knee MRIs and radiographs at a single pediatric institution identified 108 limbs (102 patients) meeting inclusion criteria. Sixty-nine limbs had no known patellar pathology (control group) and 39 had surgery for recurrent patellar dislocations (surgical group). MRI measures included tibial tuberosity-trochlear groove distance (TT-TG), tibial tuberosity-posterior cruciate ligament distance (TT-PCL), and lateral trochlear inclination (LTI). Radiographic measures included the Caton-Deschamps Index (CDI) and Insall-Salvati Index (ISI). These measures are representative of PFI risk factors, specifically patellar tendon malalignment, trochlear dysplasia, and patella alta. Binomial logistic regression was used to relate the anatomical parameters to the probability of PFI. Results: The surgical and control groups were similar in terms of age, height and weight. The logistic regression analysis indicated that the TT-TG (p=0.001) and LTI (p<0.001) were correlated with PFI. The odds ratio (95% confidence interval) was 1.19 (1.07 -1.31) for TT-TG, giving the increased probability of a knee to experience PFI for each 1 mm increase. The odds ratio was 0.85 (0.77-0.93) for LTI, showing a decrease in the probability of instability with each 1° increase. Neither CDI nor ISI measures significantly correlated with probability of PFI (p=0.30 and p=0.18, respectively). The two parameters of TT-TG and LTI accounted for 42% (Nagelkerke R2) of the variance between the control and surgical groups. Conclusion/Significance: Comparing pediatric patients with recurrent patellar dislocations to controls, logistic regression analysis suggests the likelihood of PFI correlates with the severity of specific radiographic measures, specifically those representing the degree of patellar tendon alignment (TT-TG) and trochlear dysplasia (LTI). Knowing this correlation can help guide the treatment of PFI in pediatric patients by providing physicians and families with a continuum on which to base their decisions.

Radial Artery Catheterization

Abstract Background The main cause of unsuccessful peripheral radial artery catheterization using traditional palpation is imprecisely locating the arterial center. The authors evaluated factors causing disparities between the arterial centers determined by palpation versus ultrasound. The authors applied them to create and test a novel catheterization training program. Methods The arterial central axis was determined by ultrasound and palpation in 350 adults. Potential independent predictors of disparity included sex, body mass index, pulse pressure, transverse arterial diameter, subcutaneous arterial depth, chronic hypertension, and experience as an anesthesiologist (less than 3 vs. greater than or equal to 3 yr). Using the results, the authors developed a radial artery catheterization training program. It was tested by enrolling 20 first-year interns, randomized to a training or control group. The time to successful insertion was the primary outcome measure. The success rate and time required for catheterization by palpation were evaluated in 100 adult patients per group. Results Independent predictors of central axis disparity were pulse pressure, subcutaneous radial artery depth, years of experience, and chronic hypertension. Training improved the catheterization time (training group 56 ± 2 s vs. control group 109 ± 2 s; difference –53 ± 3 s; 95% CI, –70 to –36 s; P &lt; 0.0001) and total success rate (training group 83 of 100 attempts, 83%; 95% CI, 75 to 90 vs. control group 57 of 100, 57%; 95% CI, 47 to 66; odds ratio, 3.7; 95% CI, 2.7 to 5.1). Conclusions Misjudging the central axis position of the radial artery is common with a weak pulse and/or deep artery. The authors’ program, which focused on both these issues, shortened the time for palpation-guided catheterization and improved success.

Initial Success Rate

Background: Cannulation of the radial artery can be extremely challenging in infants. Scale ultrasound can provide accurate arterial location and guidance for operators. We hypothesized that scale ultrasound helps increase the initial success rate of radial artery cannulation in this population. Method: Seventy-six infants aged 0–3 months who needed arterial puncture after general anesthesia were randomly divided into two groups (1:1 ratio): the scale ultrasound group and the traditional ultrasound group. The primary endpoints were the success rate of the first attempt and the total success rate of arterial cannulation. The secondary endpoints were the time during arterial puncture and the incidence of vascular complications. Results: The success rate of the first attempt and the total success rate of arterial cannulation were 92.1% (35/38) versus 50% (19/38) and 100% (38/38) versus 86.8% (33/38) in the scale ultrasound and traditional ultrasound group ( p < 0.005), respectively. The median time to ultrasound location, needle entry into the radial artery, and successful cannulation in the scale ultrasound group were significantly shorter than those in the traditional ultrasound group: 10 (8.0, 17.2) s, 15 (11.7, 20) s, and 65 (53.8, 78.5) s vs 30 (26.5, 43.5) s, 35 (23, 51) s, and 224.5 (123.5, 356) s ( p < 0.001), respectively. The incidence of hematoma was higher in the traditional group ( p < 0.005). Conclusions: Scale ultrasound-guided radial arterial cannulation can significantly improved initial success rate and overall success rate, shorten puncture time in infant, compared with that achieved with the use of traditional ultrasound guidance.

Abstract Objective: To assess the effect of individual compared to clinic-level feedback on guideline-concordant care for 3 acute respiratory tract infections (ARTIs) among family medicine clinicians caring for pediatric patients. Design: Cluster randomized controlled trial with a 22-month baseline, 26-month intervention period, and 12-month postintervention period. Setting and participants: In total, 26 family medicine practices (39 clinics) caring for pediatric patients in Virginia, North Carolina, and South Carolina were selected based upon performance on guideline-concordance for 3 ARTIs, stratified by practice size. These were randomly allocated to a control group (17 clinics in 13 practices) or to an intervention group (22 clinics in 13 practices). Interventions: All clinicians received an education session and baseline then monthly clinic-level rates for guideline-concordant antibiotic prescribing for ARTIs: upper respiratory tract infection (URI), acute bacterial sinusitis (ABS), and acute otitis media (AOM). For the intervention group only, individual clinician performance was provided. Results: Both intervention and control groups demonstrated improvement from baseline, but the intervention group had significantly greater improvement compared with the control group: URI (odds ratio [OR], 1.62; 95% confidence interval [CI], 1.37–1.92; P < 0.01); ABS (OR, 1.45; 95% CI, 1.11–1.88; P < 0.01); and AOM (OR, 1.59; 95% CI, 1.24–2.03; P < 0.01). The intervention group also showed significantly greater reduction in broad-spectrum antibiotic prescribing percentage (BSAP%): odds ratio 0.80, 95% CI 0.74-0.87, P < 0.01. During the postintervention year, gains were maintained in the intervention group for each ARTI and for URI and AOM in the control group. Conclusions: Monthly individual peer feedback is superior to clinic-level only feedback in family medicine clinics for 3 pediatric ARTIs and for BSAP% reduction.

Abstract Background: Given the low first-pass success rate of the conventional short-axis (SAX) or long-axis (LAX) approach, ultrasound-guided radial artery cannulation in adults with radial artery diameters less than 2.2 mm may still be challenging. In this study, we compare the efficacy of modified long-axis in-plane(M-LAIP) versus short-axis out-of-plane (SAOP) or conventional palpation(C-P) approaches for ultrasound-guided radial artery cannulation.Methods: This was a prospective, randomized and controlled trial, conducted from 1 July 2018 to 24 November 2018. A total of 201 patients (age 18 to 85 years, the diameter of the radial artery less 2.2 mm) were included. All patients were randomized 1:1:1 to the M-LAIP, SAOP or conventional palpation (C-P) approach. The primary outcome was the cannulation success rate. Secondary outcomes included first location time and cannulation time, number of attempts. The Chi-square (χ2) test was used to compare categorical data between 3 groups.Results: The cannulation success rate was significantly higher in the M-LAIP group than in the SAOP or C-P groups (first success rate: 80.3% vs 53.8% or 33.8%; p < 0.001; total success rate: 93.9% vs 78.5% or 50.8%; p < 0.001). First location time (seconds) was significantly longer in the M-LAIP group (31(28-35[12-44])) than in the SAOP (15(14-17[10-21]); p < 0.001) and C-P groups (12(8-13.5 [6-37]). However, the cannulation time (seconds) in the M-LAIP group (29(24-45[16-313])) was significantly shorter than that in the SAOP (45(28.5-135.5[14-346]); p = 0.002) and the C-P groups (138(27-308[12-363]); p < 0.001). The number of attempts was lower in the M-LAIP group compared with SAOP or C-P group (1.29±0.63 vs 1.8±0.89 or 2.22±0.93, p < 0.001).Conclusions: The use of the M-LAIP approaches significantly improved the success rate of radial artery cannulation in adults with radial artery diameters less than 2.2 mm, compared with that achieved with the use of traditional short-axis out-of-plane approach.Trial registration: ClinicalTrials.gov; No: ChiCTR-IOR-17011474; URL: http: // www. chictr.org. cn/index.aspx.
