Locoregional anesthesia (ALR) is a technique that is increasingly expanding because of its safety and safety compared with general anesthesia and axial blocks. Locoregional anesthesia has several advantages in the context of emergency surgery. They simplify pre- and postoperative management for both the patient and the healthcare team. This is a prospective study conducted over a period of one year in the emergency room of the military hospital Moulay Ismail Meknes. Patients admitted for surgical limb emergencies with severe cardiorespiratory and metabolic impairment and in whom general anesthesia or peripullary anesthesia are considered to be at high risk were included. ALR device has been a very good alternative. Our study included 30 patients including 18 men and 12 women, the mean age was 72.5 years (63-82) all our patients were classified ASA IV. 20 blocks were made at the lower limbs and 10 at the upper limbs. Ultrasound detection was performed in 16 cases and the rest by neurostimulation. The interventions were carried out without affecting the previous state of the patients with good analgesia and satisfaction of the patients. ALR represents anesthetic technique of putting by its good tolerance. This interest differs in emergencies from fragile patients. All this justifies the need for good training and mastery of these techniques by all anesthetists’ doctors.
