Hypoglycemia is now a frequent finding during both regional and general anesthesia, especially when clonidine or dexmedetomidine are used and dehydration is severe. One of the most common causes of difficult spinal anesthesia is severe dehydration, often due to diuretic abuse or inadequate fluid replacement during the nil-by-mouth period. In some cases, hypoglycemia persists even after IV dextrose administration. Here, dexamethasone injection acts as a rescuer, particularly during emergency or elective cesarean sections.
Importantly, hypoglycemia and dehydration are increasingly being observed even in non-diabetic patients. Symptoms such as drowsiness or dullness should prompt immediate blood glucose checks. Key takeaway: Anesthesiologists must remain vigilant and monitor blood glucose frequently, regardless of diabetic status, to prevent perioperative complications.
