概括

内镜液体废物占内镜废物的三分之一,可以通过固化处理,以便在垃圾填埋场处置. 与规范的医疗废物管理相比,这种方法可以降低成本和温室气体排放.

科学领域:

医疗废物管理医疗废物管理
环境科学环境科学
医疗保健的可持续性医疗保健的可持续性

背景情况:

内镜产生大量的医院废物,液体废物占总量的三分之一.
目前对内镜液体废物作为受管制的医疗废物 (RMW) 的管理需要高昂的成本和大量的温室气体 (GHG) 排放.
需要采用替代废物处理方法来减轻RMW的环境和财务负担.

研究的目的:

评估替代液体废物处理方法的碳足迹和财务影响,与内镜中的标准RMW管理相比.
评估固化和城市下水道处置 (USD) 的可行性,作为内镜液体废物RMW的替代方案.

主要方法:

在一个月内对内镜液体废物的预期称重.
使用Carebone工具计算成本 (€) 和温室气体排放量 (kgCO2e).
将RMW管理与两种替代方法进行比较:固化和城市下水道处置 (USD).

主要成果:

透视液体废物平均为每名患者1.56公斤,其中三分之一为液体.
与RMW相比,用于垃圾填埋的液体废物固化可以为治疗4000名患者的中心每年节省923欧元,并避免每年1440公斤CO2e.
城市下水道处置 (美元) 发现成本增加了105,898欧元,仅避免了96.5公斤CO2e,这表明它既不对环境也不对经济有益.

结论:

固化内镜液体废物为RMW提供了可行的替代方案,降低了成本和环境影响.
城市下水道处理 (USD) 不是处理内镜液体废物的经济或环境合理的选择.
在内镜装置中优化液体废物管理对于提高可持续性和减少与医疗保健相关的环境负担至关重要.

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Endoscopic Procedures III: Video Capsule Endoscopy

Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...

Endoscopic Procedures V: ERCP

Endoscopic Procedures V: ERCP

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.
