Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Intramuscular TXA
Tranexamic acid 1 gram administered via deep intramuscular injection into the lateral thigh or deltoid muscle prior to surgery. Anesthesia maintained with a balanced inhalational technique (isoflurane 1-1.5% in oxygen-enriched air) and baseline fluid therapy 10 ml per kg per hour of lactated Ringer's solution).
Drug: Tranexamic Acid (TXA) intarmuscular
Tranexamic acid 1 gram administered via deep intramuscular injection into the lateral thigh or deltoid muscle prior to surgery.
Active Comparator: Intravenous TXA
Tranexamic acid 1 gram administered intravenously over 10 minutes, following standard protocols, prior to surgery. Anesthesia maintained with a balanced inhalational technique (isoflurane 1-1.5% in oxygen-enriched air) and baseline fluid therapy 10 ml per kg per hour of lactated Ringer's solution).
Drug: Tranexamic Acid (TXA) intravenous
Tranexamic acid 1 gram administered intravenously over 10 minutes, following standard protocols, prior to surgery.
