Randomized Controlled Trial
Effects of a Preoperative Carbohydrate-Rich Drink Before Ambulatory Surgery: A Randomized Controlled, Double-Blinded Study.
BACKGROUND The guidelines recommend oral carbohydrates up to 2 hr before elective surgery. The objective of this study was to explore the safety and feasibility of preoperative carbohydrate drink in patients undergoing ambulatory surgery. MATERIAL AND METHODS Patients undergoing ambulatory surgery under general anesthesia were enrolled. ⋯ Blood electrolytes (sodium, potassium, calcium) and glucose concentration levels were similar in both groups at T₂. No gastric regurgitation or pulmonary aspiration was recorded. CONCLUSIONS Administration of 200 mL of oral carbohydrate beverage 2 hr before ambulatory surgery is safe, effective, and can be used for preoperative management of fasting patients.

Randomized Controlled Trial
Elevated Lateral Position Improves the Success of Paramedian Approach Subarachnoid Puncture in Spinal Anesthesia before Hip Fracture Surgery in Elderly Patients: A Randomized Controlled Study.
BACKGROUND The aim of this study was to determine whether an elevated lateral recumbent position, compared to regular lateral recumbent position, may reduce the number of needle passes and attempts required for success subarachnoid puncture in spinal aesthesia before surgery in elderly patients with hip fractures. MATERIAL AND METHODS This was a randomized controlled interventional study in Beijing Jishuitan Hospital. Patients older than 65 years of age with hip fracture orthopedics who were planned to receive subarachnoid block in the lateral recumbent position before surgery were enrolled. ⋯ The procedure process, including overall times needed for puncture, anesthesia, and surgery did not show differences between the 2 groups. Complications were few and similar between the 2 groups. CONCLUSIONS An elevated lateral recumbent position during the subarachnoid puncture in spinal anesthesia significantly reduced the needle pass numbers needed for success dural puncture, and reduced discomfort in elderly patients with hip fractures.
