Intravenous magnesium sulphate prevents intravenous salbutamol tachycardia in asthma.

its extent of spread. Being aware that multiple simultaneous CSF leaks are often present, two separate epidurals may lead to a more complete dural tamponade and better sealing in the upper cervical meninges. Injection at two separate sites may decrease the possibility of spinal compression from a large amount of blood and guarantee a more uniform distribution over the meninges. In conclusion, symptoms related to SIH are the result of a low CSF volume; a considerable spinal loss of CSF has serious complications including subdural hematoma. A two-level epidural blood patch may be an option to extend the distribution of blood when the exact CSF leak site is unknown, or following a failed lumbar patch. A greater volume of autologous blood may uniformly increase CSF pressure and replace the space of the lost CSF.
