“…It is thought that the difference in correct position of catheter tip, even though assuming the same formula, might be from that the method for identifying the optimal zone is different. We used TEE to confirm the ideal location of the catheter tip, whereas the authors used the carina on chest X-ray in the previous study [28]. We thought our study had a benefit in terms of the method to identify the SVC-RA junction and the optimal point for catheter tip placement, which was defined in the present study, because of the type of surgery requiring intraoperative TEE.…”

This prospective observational study investigated the optimal insertion depth of the central venous catheter through the right internal jugular vein using transesophageal echocardiography. After tracheal intubation, the anesthesiologist inserted a probe for esophageal echocardiography into the patient's esophagus. The investigators placed the catheter tip 2 cm above the superior edge of the crista terminalis with echocardiography, which was defined as the optimal point. We measured the inserted length of the catheter. Pearson correlation tests were performed with the measured optimal depth and some patient parameters. We made a new formula for placing the catheter at the optimal position. A total of 89 subjects were enrolled in this trial. The correlation coefficient between the measured optimal depth and the patient's parameters was the highest for patient height (0.703, p < 0.001). We made a new formula of 'height (cm)/10 -1.5 cm'. The accuracy rate of this formula for the optimal zone was 71.9% (95% confidence interval; 62.4 -81.4%), which was the highest among the previous formulas or guidelines when we compared. In conclusion, the central venous catheter tip was evaluated with transesophageal echocardiography, and we could make a new formula of 'height (cm)/10 -1.5', which seemed to be better than other previous guidelines.

“…Recently, Şahinkaya et al conducted a study to reexamine Peres' formula [28]. The authors reported that when using the Peres' formula, the correct position of the catheter tip was reached in 84.7% (133/157) of cases using the right internal jugular vein as a route for central venous catheterization.…”

“…[ 20 ] Still, the Peres equation [ 7 ] has been shown to have a lower performance in female and obese Turkish individuals. [ 6 ] Struck et al [ 21 ] showed that the Peres and Czepizak formulas performed adequately for individuals 170–180 cm tall but less well in smaller or taller individuals. In addition, those formulas have a 48%-94.5% correct placement rate.…”

“…Nevertheless, regardless of the chosen approach, it is essential to ensure that the tip of the catheter does not exceed the junction of the superior vena cava and the right atrium, making accurate preoperative estimation crucial. [3][4][5][6] Accurate catheter length estimation is expected to avoid the psychological impact on patient and infection risks secondary to catheter adjustment, especially for infusion ports.…”

This study aimed to determine an equation to estimate the optimal insertion length for catheter placement via the posterior approach of the sternocleidomastoid muscle in cancer patients. This retrospective study included patients with cancer who underwent infusion port implantation surgery in the Oncology Department of the 900th Hospital of Joint Logistic Support Force of the Chinese People Liberation Army from April 2017 to September 2023. Patient height (H), weight (W), chest length (C), and length of the internal jugular vein catheter (L) were collected from medical records. The patients were randomized 7:3 to the training and validation sets. Linear regression analyses were used in the training set to determine formulas to predict catheter length. The formula predictive value was analyzed using the Bland-Altman method in the validation set. This study included 336 patients, with a mean age of 58.27 ± 11.70 years, randomized in the training (n = 235) and validation (n = 101) sets. Linear regression analysis revealed that the equations for catheter length relative to H, body mass index (BMI), and C are L = 0.144 × H - 8.258 (R² = 0.608, P < .001), L = −0.103 × B + 17.384 (R² = 0.055, P < .001), and L = 0.477 × C + 1.769 (R² = 0.342, P < .001), respectively. The multivariable linear regression analysis showed that the equation between the length of the catheter and H and C was L = 0.131 × H + 0.086 × C-8.515 (R² = 0.614, P < .001). The Bland-Altman analysis in the validation set showed that the predicted values of internal jugular vein catheter length and the actual values showed good agreement. The optimal L might be determined by simple formulas based on patients H and C.

“…In the current case, we suggest that emphysematous thrombophlebitis may be attributed to emergency surgery, absence of anticoagulant use, insertion without ultrasound assistance, and misplacement of the CVC tip from the right subcalvian vein into the IJV[ 4 , 12 ]. The term ‘misplacement’ refers to migration of the CVC tip to an improper position[ 13 ].It is recommended that the CVC tip be positioned at the junction of the SVC and right atrium[ 14 ], a location with high blood flow to reduce the risk of thrombosis but still lying outside the atrium, thereby preventing arrhythmia[ 15 ]. In the current case, the tip of the CVC was implanted via subclavian vein access towards the head rather than caudally toward the junction of the SVC and right atrium.…”

Time series analysis is a valuable tool in epidemiology that complements the classical epidemiological models in two different ways: Prediction and forecast. Prediction is related to explaining past and current data based on various internal and external influences that may or may not have a causative role. Forecasting is an exploration of the possible future values based on the predictive ability of the model and hypothesized future values of the external and/or internal influences. The time series analysis approach has the advantage of being easier to use (in the cases of more straightforward and linear models such as Auto-Regressive Integrated Moving Average). Still, it is limited in forecasting time, unlike the classical models such as Susceptible-Exposed-Infectious-Removed. Its applicability in forecasting comes from its better accuracy for short-term prediction. In its basic form, it does not assume much theoretical knowledge of the mechanisms of spreading and mutating pathogens or the reaction of people and regulatory structures (governments, companies, etc. ). Instead, it estimates from the data directly. Its predictive ability allows testing hypotheses for different factors that positively or negatively contribute to the pandemic spread; be it school closures, emerging variants, etc. It can be used in mortality or hospital risk estimation from new cases, seroprevalence studies, assessing properties of emerging variants, and estimating excess mortality and its relationship with a pandemic.
