Endoscopic Studies II: Thoracocentesis

Endoscopic Studies II: Thoracocentesis

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Aneurysm IV: Nursing Management

Aneurysm IV: Nursing Management

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

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...

Hemodialysis II: Procedure and Complications

Hemodialysis II: Procedure and Complications

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Endoscopic Procedures I: Esophagogastroduodenoscopy

Endoscopic Procedures I: Esophagogastroduodenoscopy

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.
Nasointestinal Feeding
Nasointestinal feeding involves placing a tube through...

Summary

Restricting routine intravenous fluids (IVFs) for ambulatory gastrointestinal endoscopies to an as-needed basis increased vasopressor use but did not affect patient vital signs or procedure times. This change conserved fluids during a national shortage.

Background:

Routine intravenous fluid administration is common in ambulatory gastrointestinal (GI) endoscopies, lacking strong evidence.
A national intravenous fluid shortage necessitated a change in protocol from routine to discretionary fluid use.
This study evaluated the impact of this protocol change on patient outcomes.

Purpose of the Study:

To assess the outcomes of switching from routine to discretionary intravenous fluid administration in ambulatory GI endoscopies.
To determine if a discretionary fluid policy impacts patient safety and resource utilization.

Main Methods:

A cohort study comparing two periods: discretionary (October-November 2024) and routine (October-November 2023) intravenous fluid administration.
Data from 1827 ambulatory esophagogastroduodenoscopies and colonoscopies performed under monitored anesthesia care were analyzed.
Primary outcome was vasopressor use; secondary outcomes included vital sign changes, medication use, and procedure times.

Main Results:

The discretionary fluid group showed a higher percentage of patients receiving vasopressors (18.1% vs. 12.8%, p<0.01).
No significant differences were observed in perioperative hypotension, tachycardia, desaturation, or anesthesia/recovery times between the groups.
A total of 983 patients received discretionary fluids and 844 received routine fluids.

Conclusions:

Discretionary intravenous fluid administration for ambulatory GI endoscopies is associated with increased vasopressor use.
This approach did not lead to adverse changes in vital signs or extended procedure durations.
The findings support a more judicious use of intravenous fluids in this patient population.
