One of the common serious complications in the postoperative phase is Residual the neuromuscular blockade that confused the anesthesia medical team also patients may become uncomfortable, un ability to clear secretion, un-explanation of decreasing SPO2, increase respiratory effort and lead to an increase in the risk of respiratory complication. Most clinicians used clinical assessment to evaluate neuromuscular recovery such as a head lift for 5 seconds, Sustain leg lift, Tongue protrusion, teeth clenching, swallowing, Tidal volume 5 mL/kg, Handgrips Sustained for 5 seconds, and other clinical assessments in patients undergoing general anesthesia. A few studies have been discussing the utilization of hand dynamometers in the assessment of post-residual neuromuscular block. Our aim is to examine the neuromuscular recovery using a hand dynamometer after receiving Atracurium versus Rocuronium.
