Conditions

central venous catheterization

Interventions

The control group:canulation of central venous catheter with dilator

The test group:canulation of central venous catheter without dilator

Eligibility

Sex/Gender

All

Age

18 Years to No maximum

Inclusion criteria

Inclusion criteria: 1. Patients aged 18 years or older; 2. Patients who are scheduled to undergo right internal jugular vein catheterization based on surgical requirements or medical condition; 3. Patients for whom the anticipated duration of central venous catheter retention is expected to exceed three days, as determined by clinical assessment.

Exclusion criteria

Exclusion criteria: 1. Infection at the puncture site or cicatricial contracture may compromise the feasibility of central venous puncture. 2. Pre-puncture ultrasound examination revealed thrombosis or anatomical abnormalities in the internal jugular vein, which would impede smooth insertion of the central venous catheter. 3. Contraindications for central venous puncture exist, including but not limited to the conditions mentioned in points 1 and 2. 4. Patients with pre-existing infusion ports. 5. Patients unable to cooperate with central venous puncture under local anesthesia due to various reasons, such as psychiatric disorders. 6. Patients who decline participation, do not provide or refuse to provide informed consent. 7. Patients concurrently enrolled in other studies that could interfere with this study.
