Day case surgery involves admitting selected patients to the hospital for a planned procedure and discharging them home on the same day. It aims to be safe, efficient, and performed according to a set pathway. Over 200 procedures are now considered suitable for day case surgery. Patient selection criteria focuses on those at low risk of complications and able to eat/drink orally after surgery. Preoperative assessment educates patients on the process and identifies medical risks. Advantages include reduced costs and improved patient comfort and control. Discharges require stable vital signs, adequate pain control, and ability to care for oneself at home. Common pediatric day cases include circumcision, hernia repair, and cyst removal.
