An Exploratory Study of Perioperative Venous Access in Obese Patients

An Exploratory Study of Perioperative Venous Access in Obese Patients

This study is intended to explore the application effect of long peripheral intravenous catheters(LPCs) and midline catheters(MCs) in the perioperative period of obese patients, aiming at providing the scientific basis for the optimal perioperative venous access for the obese patients.

This study is intended to explore the application effect of long peripheral intravenous catheters(LPCs) and midline catheters(MCs) in the perioperative period of obese patients; at the same time, the LPCs will be used as the control group and the MCs as the experimental group, to compare whether the application of LPCs in the perioperative period of obese patients is not inferior to that of the MCs; the comprehensive comparison of the effect of the clinical application and the evaluation of the health economics, aiming at providing the scientific basis for the optimal perioperative venous access for the obese patients.

Inclusion Criteria:

• Obese patients (BMI ≥ 30kg/m2) who are to undergo surgery.
• Expected length of hospitalisation within 2 weeks.
• Conscious and able to communicate normally.

Exclusion Criteria:

• It is expected that perioperative medications will need to be infused via a central venous catheter (e.g. total parenteral nutrition TPN);
• Patients with an indwelling central venous catheter on admission
