Intramuscular Ephedrine in the Prevention of Hypotension in Patients Undergoing Spinal Anesthesia
Subarachnoid anesthesia is an alternative and usually the first choice for many surgical procedures. It is a simple and safe procedure, however it can present complications such as hypotension and bradycardia.
