GENERAL ANESTHESIA

This trial tests whether adding dexmedetomidine or magnesium sulphate to lidocaine for a peribulbar block (anesthesia around the eye) helps keep heart rate and blood pressure steady during dacryocystorhinostomy (tear duct surgery) under general anesthesia. Sixty adults undergoing…

This study tests whether a nerve block (injecting numbing medicine near a nerve cluster in the face) can improve the surgical view and reduce pain for people having pituitary tumor surgery through the nose. 70 adults will be randomly assigned to receive either the nerve block plu…

This study is testing whether giving a caffeine tablet under the tongue at the end of surgery can help elderly patients (65 and older) wake up faster and feel less agitated after general anesthesia. Half of the 50 participants will get caffeine, the other half a placebo. The goal…

This study tests whether giving dexmedetomidine and esketamine during and after surgery can help patients recover better. 316 adults having general anesthesia will receive one or both drugs, and their recovery quality will be measured using a 15-item questionnaire. The goal is to…

This study watches 100 adults having lung surgery to see if one type of anesthesia leads to faster recovery. Patients get either a computer-controlled IV drip or inhaled gas, based on their doctor's usual practice. Researchers track how quickly patients wake up, breathe on their …

This study is a large registry that collects information from hospitals across the U.S. on pregnant women who receive general anesthesia during a cesarean delivery. Researchers aim to understand why general anesthesia is used, how it is managed, and what outcomes occur for both m…

This study observes 150 adults undergoing rapid sequence induction, a common emergency anesthesia technique. Researchers will use a special monitor (ANI) to measure pain levels during intubation, along with tracking complications like low oxygen or blood pressure. The goal is to …

This study compares two types of breathing tubes (i-gel and Protector) used during minor urology procedures under general anesthesia. About 100 adults will take part to see which device seals the airway better and works best in different head positions. The goal is to improve saf…

This study looks at whether doing periodic lung recruitment maneuvers (a technique to reopen collapsed lung areas) during spine surgery helps reduce lung collapse compared to the standard single-time approach. Sixty adults having elective spine surgery while lying face-down will …

This study looks at two different breathing settings (1:2 vs. 1:3 inspiratory-to-expiratory ratio) used during anesthesia in children aged 2-12 having dental procedures. Researchers will measure vital signs, breathing quality, and recovery to see which setting leads to smoother e…

This study compares two muscle relaxant drugs (rocuronium and cisatracurium) used during general anesthesia in people with chronic kidney disease. Researchers want to see which drug leads to fewer lung problems after surgery. About 490 adults with kidney disease will take part.

This study looks at whether a simple ultrasound test before surgery can predict if a patient will have dangerously low blood pressure after receiving anesthesia for brain surgery. Researchers will measure the size and flexibility of a major vein and artery using ultrasound in 36 …

This study tests whether electronic stethoscopes placed on the chest can accurately monitor breathing in 30 adults under general anesthesia. The goal is to help anesthesiologists quickly detect breathing problems like airway blockages or low airflow. If successful, this approach …

This study looks at whether bladder tumor surgery and general anesthesia can cause short-term memory or thinking problems. Researchers will test 42 adults before and after surgery using simple cognitive tests and blood markers of brain injury. The goal is to understand who might …
