Quality Improvement Project to Reduce Preoperative Fasting Times Before Elective Procedures

This single-center quality improvement project evaluates preoperative fasting times before elective procedures requiring anesthesiology care. The project aims to reduce prolonged fasting for clear fluids by implementing a local standard operating procedure (SOP) allowing patients to drink clear liquids until being called to the operating room ("drink until called"), supported by staff education and fasting instruction cards. Fasting times and selected perioperative outcomes will be assessed before and after implementation.

Impact of Different Fasting Strategies on Gastric Ultrasound and Anxiety Levels in Children

Children who undergo surgery are usually asked to stop eating and drinking for several hours before anesthesia to reduce the risk of stomach contents entering the lungs. However, long fasting times may cause discomfort, dehydration, low blood sugar, and increased anxiety in children. Recent guidelines suggest that clear liquids can safely be allowed closer to the time of surgery, and some enhanced recovery protocols even recommend giving carbohydrate-containing drinks before anesthesia. This study will compare three different preoperative fasting approaches in children undergoing elective inguinoscrotal surgery: traditional fasting, preoperative carbohydrate drinks, and the "Sip-Til-Send" approach, which allows clear fluids until the child is called to the operating room. The children's anxiety levels will be evaluated before surgery using a validated anxiety scale and assess stomach content and volume using gastric ultrasound. The secondary outcomes such as nausea, vomiting, pain, emergence delirium, and blood glucose levels will be evaluated. The results may help determine safer and more comfortable fasting strategies for children undergoing surgery.

Baseline Gastric Volume in Diabetic vs Non-Diabetic Patients

During the preoperative preparation process, the fasting period for anesthesia is planned according to guidelines. According to standard guidelines, a fasting period of at least 2 hours is recommended for clear liquids, at least 6 hours for light meals, and at least 8 hours for a full meal. However, it has been reported that these guidelines are valid for healthy patients. It is thought that the planned fasting periods may vary in diabetic patients due to delayed gastric emptying. This study aims to calculate gastric volume under ultrasonography guidance and compare it with fasting time.

Effect of Preoperative Oral Carbohydrate Drink on ObsQoR-10 Score After Elective Cesarean Under Neuraxial Anesthesia

The goal of this clinical trial is to determine whether a preoperative oral carbohydrate-rich clear drink can improve recovery in women undergoing elective cesarean section under neuraxial anesthesia. The main outcomes it aims to answer are: Primary Outcome: Does the carbohydrate drink improve ObsQoR-10 scores at 24 and 48 hours postoperatively? Secondary Outcomes: Does it reduce patients' hunger, thirst, and anxiety levels? Researchers will compare patients receiving a 400 ml oral carbohydrate-rich clear drink 2 hours before surgery (Group A) to those receiving 400 ml distilled water (Group B), to assess differences in recovery and comfort. Participants will: Be randomized into two equal groups (n=50 each) using a computer-generated randomization table Receive standardized anesthesia and postoperative analgesia

Intermittent Fasting Versus Carbohydrate Drinks Before Surgery

The purpose of this study is to investigate whether time-restricted feeding, a form of intermittent fasting, before surgery improves insulin resistance around the time of surgery, compared to carbohydrate drinks and standard fasting before surgery.
