Intraoperative surgical losses for a minimal-herniorrhaphy are estimated at?

• A. 0-2 ml/kg/hr
• B. 2-4 ml/kg/hr
• C. 4-6 ml/kg/hr
• D. 6-8 ml/kg/hr

Answer: (A)

Intraoperative blood loss is often thought of in milliliters per kilogram per hour to compare across patients and operative times. A minimal-herniorrhaphy involves only small incisions and limited vessel injury, so the bleeding rate is very low. That makes 0-2 ml/kg/hr the best estimate because it reflects the minimal blood loss expected with such a superficial, short procedure. The higher ranges correspond to more extensive surgeries with greater tissue dissection and vascular disruption, which isn’t typical for a minimal herniorrhaphy. For a 70 kg patient, this range translates to up to about 140 mL per hour, but most cases stay well below that.
