OPTIC NERVE SHEATH DIAMETER

This study tested a treatment for severe headaches that can happen after a spinal tap or epidural. Doctors used a special injection made from the patient's own blood (plasma rich fibrin) to try to stop the headache. The study included 60 adults aged 18 to 65 who had this type of …

This study looked at how two different anesthesia drugs—desflurane and propofol—affect the thickness of the sheath around the optic nerve during laparoscopic gallbladder removal. 146 adults aged 18-60 with mild health issues took part. The goal was to see if one drug causes less …

This study looked at whether ultrasound can measure changes in the optic nerve sheath (the lining around the eye nerve) during liposuction surgery. The goal was to see if body position and fluids affect brain pressure. 55 adults having liposuction took part. The study was complet…

This study looked at whether keyhole (laparoscopic) surgery affects pressure inside the skull. Doctors used a simple ultrasound of the eye nerve to check for pressure changes in 55 adults. The goal was to see if this safe, non-invasive method can help monitor patients during surg…

This study looked at 63 women having laparoscopic hysterectomy surgery while tilted head-down. Researchers compared two anesthetics, sevoflurane and desflurane, to see how they affected pressure inside the head by measuring the nerve sheath at the back of the eye using ultrasound…

This study looked at whether ultrasound measurements of the optic nerve sheath (the lining around the eye nerve) can detect changes in brain pressure during open-heart surgery that uses a heart-lung machine. Researchers measured this in 40 adults undergoing elective heart surgery…

This study looked at 309 older adults with a type of heart failure called HFpEF to understand why some develop atrial fibrillation (AFib), an irregular heartbeat. Researchers measured fluid pressure in the body and brain using ultrasound and found that higher pressure in the vein…

This study looked at 105 adults having spine surgery to see if different ventilator pressure levels (5 vs 10 cmH2O) change the size of the optic nerve sheath, which can indicate pressure inside the brain. The goal was to understand how breathing machine settings might affect the …

This study looked at how different amounts of anesthesia gas affect the size of the optic nerve sheath (the covering of the eye nerve) during open gynecological surgery. Researchers measured the nerve sheath using ultrasound in 80 adults before, during, and after surgery. The goa…
