Data were collected from the records of patients aged under 18 years who required CVC placement using LMT or US between June and November 2016 at the Hernando Moncaleano Perdomo University Hospital. We collected anthropometric data (age, gender, weight, height, body mass index) and the ASA class of each patient, together with data relating to the procedure (technique, approach, indication, operator, access route, type of catheter) and procedure-related complications. All parameters were uploaded to a data collection sheet designed using the freeware Google Forms application; the data was automatically coded and tabulated in Excel 2010 and processed for analysis in SPSS version 23. Patients with umbilical and peripherally inserted central catheters were excluded. Approval was obtained from the hospital's ethics committee and recorded in minutes no. 001-002 of January 26, 2017.Statistical analysisProportions were calculated for qualitative variables and measures of central tendency and dispersion for quantitative variables. The different placement techniques were compared by means of the chi-square test, the Student's t test and the Mann–Whitney U test. The frequency of occurrence of complications with each technique was analysed. Correlation coefficients were calculated for the association between quantitative variables with their confidence intervals (CI). CIs were monitored and statistical significance was set at p≤0.05.ResultsWe identified 227 patients with CVC; data was incomplete in 26 cases (11%), and these patients were excluded, leaving 201 patients with complete clinical records. In 143 cases (71%), the CVCs were placed using LMT and in 58 (29%) US was used.Patient characteristicsThe average age of patients was 4.1 years, 72% of patients were aged under 5 years (standard deviation: 48 months). Nearly all (91%) were ASA class III and IV. US was used more frequently in older patients and patients with ASA class IV; however, these differences were not statistically significant (<a class="elsevierStyleCrossRef" href="#tbl0005">Table 1</a>).<elsevierMultimedia ident="tbl0005"></elsevierMultimedia>Immediate complicationsImmediate complications occurred in 37 (18.4%) patients: 12% with US and 20.9% with LMT (OR: 0.51; 95% CI: 0.213–1.254; p=0.13), with a risk reduction percentage of 42.8% and an absolute risk reduction of 9 points when US was used vs LMT (<a class="elsevierStyleCrossRef" href="#tbl0010">Table 2</a>). The most frequent immediate complications were unsuccessful guide wire insertion and multiple punctures (<a class="elsevierStyleCrossRef" href="#tbl0015">Table 3</a>). Nearly all (90%) complications occurred in children under 5 years of age. Newborns presented more complications with US (<a class="elsevierStyleCrossRef" href="#tbl0020">Table 4</a>).<elsevierMultimedia ident="tbl0010"></elsevierMultimedia><elsevierMultimedia ident="tbl0015"></elsevierMultimedia><elsevierMultimedia ident="tbl0020"></elsevierMultimedia>No immediate complications occurred when the procedure was performed electively. Fewer complications occurred when the CVC was inserted in the operating room vs the ward (OR: 0.56; 95% CI: 0.23–1.37; p=0.22). In the emergency room, all CVCs were inserted using the LMT technique, and the highest percentage of immediate complications occurred in this setting (OR: 2.95; 95% CI: 1.13–7.68; p=0.03); this finding was both clinically and statistically significant (<a class="elsevierStyleCrossRef" href="#tbl0020">Table 4</a>).Patients in whom CVC was indicated due to the absence of peripheral venous access presented the highest percentage of immediate complications; of these, complications arose in all procedures performed with US (100%) and in 33% of those performed with LMT. No complications arose in cases where the CVC was placed for monitoring (<a class="elsevierStyleCrossRef" href="#tbl0020">Table 4</a>).Complications were more frequent when the CVC was placed by a paediatric surgeon (OR: 1.73; 95% 95% CI: 0.8–3.7; p=0.21); fewer paediatric surgeons used US (14.2%). Fewer complications arose when the procedure was performed by an anaesthesiologist (OR: 0.28; 95% CI: 0.06–1.24; p=0.12); a greater percentage of anaesthesiologists used US, and when they did, no complications arose. Access from the left side of the neck presented the highest percentage of immediate complications (<a class="elsevierStyleCrossRef" href="#tbl0020">Table 4</a>).Characteristics of the procedureThe procedure was usually performed urgently (94.5%) and in the paediatric ICU (61.7%). US was used more frequently in the operating room and ICU, being used in only 4.5% of the cases undergoing placement in the emergency room and on the ward. This difference was statistically significant (<a class="elsevierStyleCrossRef" href="#tbl0025">Table 5</a>).<elsevierMultimedia ident="tbl0025"></elsevierMultimedia>The most frequent indication for CVC placement was administration of vasoactive drugs. US was most frequently used by anaesthesiologists (<a class="elsevierStyleCrossRef" href="#tbl0025">Table 5</a>).The most common sites for CVC access were the internal jugular (42%) and femoral jugular (40%) veins, mostly from the right side. Fewer complications arose when the femoral approach was used (OR: 0.7; 95% CI: 0.3–1.5), and most when the internal jugular vein was used (OR: 1.2; 95% CI: 0.5–2.4). US was more often used when inserting the CVC in the right internal jugular vein (52.3%) and left subclavian vein (50%) (<a class="elsevierStyleCrossRef" href="#tbl0025">Table 5</a>).The first-attempt success rate was 91.4% (53/58) for US and 77.6% (111/143) for LMT.DiscussionCVC insertion is associated with a complication rate of between 5% and 20%; 20% of these are immediate complications.<a class="elsevierStyleCrossRefs" href="#bib0145">9,10,13</a> Our data were similar, with an overall rate of immediate complications of 18.4%. Fewer complications arose when US was used (12% vs 20.9%). This difference was clinically, though not statistically, significant, and represents a percentage risk reduction of 42.8% and an absolute reduction of 9 points.The success rates observed in our study are 91.4% with US and 77.6% with LMT. These data are in line with those of another study in which the success rate with US was 91.5% vs 72.5% with LMT.<a class="elsevierStyleCrossRef" href="#bib0120">4</a> Another study reports a 22% increase in success rates in internal jugular vein CVC placement when the procedure is performed using US.<a class="elsevierStyleCrossRef" href="#bib0115">3</a> They are also consistent with a study evaluating US-guided CVC placement success rates in populations weighing under 20kg. In this case, the success rate in infants aged under 3 months was 81.3% and 100% in those aged over 3 months.<a class="elsevierStyleCrossRef" href="#bib0145">9</a>US for CVC placement is underutilised, despite its impact on patient safety.<a class="elsevierStyleCrossRefs" href="#bib0125">5,9,13,17</a> In our study, the overall use of US was low (28.9%), with anaesthesiologists (46.4%) making the most use of this technique. Other studies report rates of between 33% and 58% of US-guided CVC insertion.<a class="elsevierStyleCrossRefs" href="#bib0125">5,13</a>The diameter of the patient's vessels is strongly correlated with age and weight, and this influences the success or difficulty of the procedure.<a class="elsevierStyleCrossRef" href="#bib0120">4</a> Our study shows that complications occurred most frequently in low-weight patients (mean 9.6kg). This is consistent with the literature, where lower success rates, more punctures and greater risk of complications are reported in low-weight patients (<16.25kg), regardless of the technique used.<a class="elsevierStyleCrossRef" href="#bib0145">9</a>In our study, US was used more frequently in older, higher-weight patients vs LMT. The technical difficulty of using large ultrasound probes in very small patients may explain these findings. Similar findings were reported in a study in 168 patients in a paediatric emergency department: US-guided CVC placement was used in older, higher-weight patients (median 13.1 years and 40kg) vs LMT (median 7.5 years and 22kg). The authors concluded the US-guided CVC is safer in older patients.<a class="elsevierStyleCrossRef" href="#bib0125">5</a> Evidence in the literature supports the efficacy and safety of real-time US internal jugular CVC placement in low-weight infants.<a class="elsevierStyleCrossRefs" href="#bib0190">18,19</a>In our study, we observed that US-guided CVC placement was most often chosen by anaesthesiologists (46%), followed by paediatricians (30%). A similar rate of use among anaesthesiologists (39%) has also been reported in the literature.<a class="elsevierStyleCrossRef" href="#bib0145">9</a> Studies have shown that the success rate of CVC placement in the internal jugular vein increased when using US<a class="elsevierStyleCrossRef" href="#bib0115">3</a>; however, the first option among paediatric surgeons is the subclavian approach, and few use the US technique. The lowest complication rate is observed when the procedure is performed by a paediatric surgeon (2.8%) vs non-surgeon (10%).<a class="elsevierStyleCrossRef" href="#bib0165">13</a> A recent study showed that CVC placement by paediatric surgeons was more successful when performed with US compared to LMT.<a class="elsevierStyleCrossRef" href="#bib0120">4</a> In contrast to the literature, in our series paediatric surgeons made less use of US and presented more immediate complications. This may be due to the fact that such surgeons are involved in more technically difficult cases.Our data show that US is not used in the emergency room, and is used most in operating rooms and paediatric ICUs. Worldwide, US is used in paediatric emergency departments primarily for therapeutic and diagnostic purposes (61% of cases), followed by CVC placement.<a class="elsevierStyleCrossRef" href="#bib0135">7</a>Critically ill patients frequently present hypotension, which is treated by administering vasoactive drugs via a central line. In our study, the most frequent indication for CVC was infusion of vasoactive drugs (74.6%).<a class="elsevierStyleCrossRef" href="#bib0125">5</a> More complications (46%) occurred in patients receiving a central line due to the absence of peripheral vein access. This is consistent with a recent study in 175 patients, which showed that 41% were catheterised using LMT vs 47% using US.<a class="elsevierStyleCrossRef" href="#bib0125">5</a> Another study that included 1134 procedures showed that the most frequent indication (36%) for US-guided CVC is the lack of peripheral venous access.<a class="elsevierStyleCrossRef" href="#bib0165">13</a>In our study, the most frequent CVC placement sites were the right internal jugular and right femoral veins; this is consistent with the literature. The femoral approach presented fewer complications. The internal jugular vein approach was associated with more complications, possibly due to the scant use of US (30%). When using US, the internal jugular vein approach is usually preferred over the subclavian access because it is easier to perform and has a lower risk of complications.<a class="elsevierStyleCrossRefs" href="#bib0115">3,5,12,14</a> According to the literature, the most frequent access sites are the internal jugular vein, the subclavian vein and the femoral vein.<a class="elsevierStyleCrossRef" href="#bib0145">9</a>The ASA clinical practice guidelines recommend using checklists or protocols for the placement and maintenance of CVCs.<a class="elsevierStyleCrossRef" href="#bib0175">15</a> Correct positioning of the tip of the CVC should be confirmed on X-ray or US imaging to prevent short-term complications caused by incorrect positioning of the catheter.<a class="elsevierStyleCrossRefs" href="#bib0105">1,4,20</a> The CVC insertion protocols used in our hospital do not include the use of US, but stress the importance of the practitioner recording the procedure in the patient's records and confirming the position of the CVC after placement. In this series, chest radiography confirmation was requested only in 45.7% of cases, and of these, only 33.7% of records contained the reading or interpretation of the operator. Most of the data obtained were taken from nursing notes and not from medical records, and data was missing in 11% of cases. This, in our opinion, is high, and shows the need for improvements in record-taking on the part of specialists.ConclusionsUS guidance reduced the frequency of immediate complications in CVC placement in children under 18 years of age, and improved the success rate in 13.8% of cases, thereby improving patient safety.Our data suggest that fewer immediate complications occur when central venous catheterisation in children is performed in operating rooms, electively, by an anaesthesiologist, and under US guidance. Conversely, complications increase in young, low-weight, low-height patients, critical patients, ASA IV patients with no peripheral venous access, and in urgent procedures using the internal jugular approach, performed by paediatric surgeons in the emergency room/hospital ward using LMT.It is important to record the procedure on the patient's medical records in accordance with institutional rules. This will enable clinicians to identify the factors associated with complications and thus implement preventive measures.Conflicts of interestThe authors declare that they have no known conflicts of interest associated with this publication, and they have received no financial support for this work that could have influenced its outcome."

This can lead to an increase in immediate complications, which can be reduced when using ultrasound. In our institution, the percentage of these complications and the use of ultrasound are unknown. ObjectiveTo describe the frequency of immediate complications of central venous catheterisation guided by the ultrasound in a general university hospital, compared to the anatomical landmarks technique in children less than 18 years of age. Materials and methodsObservational, retrospective, and analytical study, comparing the frequency of complications with two central venous catheterisation techniques: anatomical landmarks and ultrasound, according to the clinical records of procedures performed from June to November 2016. ResultsA total of 201 procedural records were analysed, of which 71% were with landmarks, and 29% with ultrasound. The overall incidence of immediate complications was 18.4%, with 12% using ultrasound and 21% using landmarks (OR: 0.5; 95 CI: 0.2–1.2). Children under 5 years of age presented with 90% of the complications, the most frequent being the impossibility of passing the guide (29.7%) and multiple punctures (24.3%). There was no arterial puncture with use of ultrasound. Ultrasound was used by 13.4% of paediatric surgeons, by 32.4% of paediatricians, and 46.4% of anaesthetists, with complications of 25%, 19%, and 7%, respectively. The main indication for catheterisation was the need for vasoactive agents (74%), with the procedure being more complicated in patients with no peripheral venous accesses (46%). The success rate with anatomical landmarks was 77.6%, compared to 91.4% with ultrasound.
