Eye scan to predict headache after spinal anesthesia for C-section

This trial measures how well two monitoring tools (optic nerve ultrasound and brain oxygen levels) can predict headache after a planned cesarean. It may help find better ways to prevent post-dural puncture headache.

This trial tests if a combination of neostigmine and atropine works better than lidocaine for treating severe headaches that can happen after spinal anesthesia during a planned C-section. It aims to find a more effective way to relieve this type of headache.

This study looks at whether living at higher or lower altitudes changes the risk of a specific headache after a C-section done with spinal anesthesia. The goal is to understand who is more likely to get this headache so care can be better tailored.

This trial tests two different ways to inject spinal anesthesia—through the middle or the side of the back—to see which causes fewer headaches afterward. If you're having orthopedic or urology surgery with spinal anesthesia, you may be able to join.

This study looks at whether a simple blood test result (the ratio of two types of white blood cells) can help predict and understand a common headache after spinal anesthesia during C-section. If you qualify, your existing medical records will be reviewed—no extra visits or procedures needed.

This trial compares two types of needles used for spinal anesthesia to see if one type causes less pressure change around the optic nerve. If you are having lower leg or knee surgery with a tourniquet and are generally healthy, this study may be for you.
