1例PICC中线导管应用在减重手术患者中的护理体会

Obese patients tend to accumulate fat on their blood vessel walls, which can also be surrounded and compressed by fat, leading to increased blood flow resistance, less smooth blood vessels, and reduced wall elasticity. Postoperative fasting in obese patients not only requires intravenous therapy such as fluid replacement and acid suppression for up to 3 days, but also early activity to promote rapid recovery. Therefore, venous access should not only meet the clinical needs for rapid fluid replacement, but also maintain patency during the activity process. Given the above characteristics, it is extremely important to choose an effective intravenous fluid replacement channel for obese patients. The American Society of Venous Infusion Nursing (INS) 2021 infusion treatment practice standard proposes the use of Sedinger or modified Sedinger technique for catheterization, which can improve puncture success rate and reduce complications. The use of midline catheters in weight loss surgery for obese patients can not only meet the needs of long-term intravenous infusion treatment, but also alleviate patient pain, protect blood vessels, and alleviate the pressure of frequent punctures by nurses. After inserting a midline catheter, there is no need for X-ray localization, reducing radiation damage and patient treatment costs.
