What volume should not exceed during a deltoid injection?

During a deltoid injection, the recommended volume should not exceed 1 mL. This limitation is primarily due to the anatomical structure of the deltoid muscle and its capacity to effectively accommodate the injected fluid. The deltoid muscle, while being a commonly used site for intramuscular injections, can only hold a small volume without risking muscle damage or discomfort to the patient. Injecting too much fluid into this site can lead to complications such as localized pain, irritation, and the potential for abscess formation.

Furthermore, the smaller volume ensures that the medication can be absorbed properly and minimizes the risk of complications associated with larger volumes, such as necrosis of muscle tissue. Proper technique and adherence to these limits are crucial for ensuring patient safety and achieving the desired therapeutic effect.
