SPINAL ANESTHESIA

This study compares two medications—dexmedetomidine and low-dose ketamine—given as a single dose before a planned C-section under spinal anesthesia. Both groups then receive a steady infusion of dexmedetomidine to keep them comfortable. Researchers will measure how well each drug…

This study tests whether a targeted nerve block (fascia iliaca compartment block) can control pain as well as spinal anesthesia during surgery to remove a blood clot from the leg artery. About 84 adults aged 40-65 scheduled for this surgery will receive either the nerve block or …

This study looked at whether a nerve block given before spinal anesthesia can reduce pain when positioning hip fracture patients for surgery. 132 older adults took part, with half receiving the block and half not. Researchers measured pain levels at rest, during positioning, and …

This study aimed to find the right dose of a spinal anesthesia drug (bupivacaine) for women with a BMI over 50 undergoing a planned C-section. Researchers tested different doses in 45 women to see which dose worked best without needing extra pain relief. The goal is to improve sa…

This study compared two ways to numb the leg for outpatient vein ablation surgery: a femoral nerve block (injecting lidocaine near the groin) and low-dose spinal anesthesia (injecting bupivacaine into the spine). Forty adults aged 18-80 with mild to moderate health status took pa…

This study compared two spinal anesthetics—prilocaine and bupivacaine—in 142 women having planned C-sections. Researchers measured how quickly each drug caused numbness and muscle relaxation, and how long those effects lasted. The goal was to see if prilocaine could be a good alt…

This study looked at 93 adults having bladder tumor surgery under spinal anesthesia. It compared two intravenous drugs—magnesium sulfate and dexmedetomidine—to see which better controlled pain after surgery. Magnesium sulfate led to lower pain scores, delayed the need for extra p…

This study compared two types of anesthesia for people having hip fracture surgery: a spinal block that numbs only one side and a nerve block in the lower back. Researchers wanted to see which method keeps blood pressure more stable and provides better pain control during surgery…

This study tested whether an intravenous fat emulsion called intralipid can reverse the effects of spinal anesthesia in people having day surgery. Two hundred adults aged 18 to 65 took part. Researchers measured how quickly motor function returned and when patients were ready to …

This study compared a new patient positioning method, called the Imran Technique, with the standard sitting position for spinal anesthesia and lumbar puncture. 200 adults took part to see if the new approach improved first-attempt success, procedure time, and comfort. The goal wa…

This study looked at 100 pregnant women having planned C-sections to see if the time it takes to deliver the baby affects the baby's cord blood pH and base excess—measures of newborn health. Researchers compared general and spinal anesthesia to see if the type of anesthesia chang…

This study looked at how the position of a patient's arms during spinal anesthesia affects pressure inside the eye. Sixty adults having hernia repair were randomly placed with arms at their sides or hands on their chest. Eye pressure was measured before and after anesthesia to se…

This study compared penile length in 200 adult men undergoing cystoscopy under spinal anesthesia versus general anesthesia. Researchers measured length and asked surgeons to rate satisfaction with access. The goal was to see if anesthesia choice affects penile size during the pro…

This study tested whether using ultrasound to guide spinal anesthesia is better than the traditional method of feeling for landmarks. 136 adults having elective surgery were randomly assigned to either ultrasound guidance or conventional palpation. Researchers measured how long t…

This completed study looked at 70 patients over 65 years old undergoing hip surgery. Researchers compared two forms of spinal anesthesia (hypobaric and hyperbaric bupivacaine) to see which one causes fewer blood pressure drops. The goal is to find a safer option for older adults,…

This study looked at 80 adults aged 45-85 having knee replacement under spinal anesthesia. Researchers checked their ECG before and after surgery to see if the anesthesia changed the heart's electrical axis. The goal was simply to observe and measure any changes, not to treat or …

This completed study looked at 3,597 patients to see if using real-time ultrasound to guide spinal anesthesia is faster and safer than the traditional landmark method. The main focus was on the time from entering the operating room to the first incision. Researchers hope ultrasou…

This completed study looked at 94 women who had a planned C-section under spinal anesthesia. Doctors compared two drugs used to prevent low blood pressure: a continuous drip of phenylephrine versus bolus injections of ephedrine. The main goal was to see which approach led to heal…

This study tested whether a passive leg raising test, done before spinal anesthesia, can predict low blood pressure in women having planned C-sections. Researchers measured heart function with ultrasound before and after raising the legs. They then tracked blood pressure drops an…
