Effect of Caudal Block Injection Rate on Optic Nerve Sheath Diameter in Pediatric Surgeries

Caudal Block, Optic Nerve Sheath Diameter

Our prospective observational study will include patients between the ages of 1-7 years, ASA 1-2, who will undergo elective surgery under general anesthesia, whose consent was obtained by their parents for the procedure to be performed. Optic nerve sheath diameter of the patients will be measured and recorded.

The study will be conducted with patients who will undergo elective surgery and caudal block will be applied between 05.07.2023-05.09.2023 in the Anesthesiology and Reanimation Clinic of Prof. Dr. Cemil Taşçıoğlu City Hospital after Ethics Committee approval and written and verbal consent of the patients. Our prospective observational study will include patients between the ages of 1-7 years, ASA 1-2, who will undergo elective surgery under general anesthesia, whose consent was obtained by their parents for the procedure to be performed. Gender, age, weight, height, body mass index (BMI), ASA (American Society of Anesthesiology) score and medical history of the patients will be recorded. Injection times of pediatric patients who underwent caudal block with 0.125% bupivacaine at a dose of 0.8 ml/kg using a 22 gauge caudal needle will be noted. Optic nerve sheath diameter of the patients will be measured and recorded. Intraoperative hemodynamic parameters, postoperative complications (nausea, vomiting, urinary retention) will also be noted.
