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...

Metabolic States of the Body: Fasting and Starvation

Metabolic States of the Body: Fasting and Starvation

During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...

Kidney Transplant II: Surgical Procedure

Kidney Transplant II: Surgical Procedure

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...

Bioavailability Study Design: Healthy Subjects Versus Patients

Bioavailability Study Design: Healthy Subjects Versus Patients

Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...

Summary

This clinical audit reviewed preoperative fasting guidelines. Excessive fasting in surgical patients leads to adverse health effects like hunger and distress.

Area of Science:

Clinical Audit
Surgical Patient Care

Background:

Preoperative fasting is a standard practice for elective surgery.
Guidelines for fasting durations exist, such as those from the Royal College of Nursing (2005).

Purpose of the Study:

To audit adherence to preoperative fasting guidelines.
To assess patient outcomes related to preoperative fasting durations.

Main Methods:

Clinical audit methodology was employed.
Data collected on patient fasting periods and reported symptoms.

Main Results:

Adherence to guidelines was examined.
Patients experiencing prolonged preoperative starvation reported negative health impacts.
Reported issues included hunger, distress, and nausea.
