Central venous catheterization is a vital procedure for volume resuscitation, infusion of drugs, and for central venous pressure monitoring in the perioperative period and intensive care unit (ICU). It is associated with position-related complications like arrhythmia's, thrombosis, tamponade, etc. Several methods are used to calculate the catheter insertion depth so as to prevent these position-related complications.
To compare Peres' formula and radiological landmark formula for central venous catheter insertion depth through right internal jugular vein (IJV) by the anterior approach.
A total of 102 patients posted for elective cardiac surgery were selected and divided into two equal groups-Peres' group (group P) and radiological landmark group (group R). Central venous catheterization of right IJV was done under ultrasound (USG) guidance. In group P, central venous catheter insertion depth was calculated as height (cm)/10. In group R, central venous catheter insertion depth was calculated by adding the distances from the puncture point to the right sternoclavicular joint and on chest X-ray the distance from the right sternoclavicular joint to carina. After insertion, the catheter tip position was confirmed using transesophageal echocardiography (TEE) in both the groups.
About 49% of the catheters in group P and 74.5% in group R were positioned optimally as confirmed by TEE, which was statistically significant. No complications were observed in both the groups.
Radiological landmark formula is superior to Peres' formula for measuring optimal depth of insertion of right internal jugular venous catheter.

中心静脉置管是围手术期和重症监护病房（ICU）进行容量复苏、药物输注以及中心静脉压监测的重要操作。它与心律失常、血栓形成、心包填塞等与位置相关的并发症有关。为预防这些与位置相关的并发症，人们采用了多种方法来计算导管插入深度。
比较通过前路经右颈内静脉（IJV）进行中心静脉置管时佩雷斯公式和放射学标志公式在确定导管插入深度方面的差异。
选取102例行择期心脏手术的患者，将其平均分为两组——佩雷斯组（P组）和放射学标志组（R组）。在超声（USG）引导下进行右颈内静脉中心静脉置管。P组中，中心静脉导管插入深度按身高（厘米）/10计算。R组中，中心静脉导管插入深度通过将穿刺点至右胸锁关节的距离与胸部X线片上右胸锁关节至隆突的距离相加得出。置管后，两组均使用经食管超声心动图（TEE）确认导管尖端位置。
经TEE确认，P组约49%的导管位置最佳，R组为74.5%，差异具有统计学意义。两组均未观察到并发症。
在测量右颈内静脉导管最佳插入深度方面，放射学标志公式优于佩雷斯公式。
