ASSESSMENT OF THE EFFICIENCY OF ANALGETIC ACTION OF ULTRASOUND-GUIDED FICB AS A COMPONENT OF PERIOPERATIVE MULTIMODAL ANALGESIA IN ERAS- STRUCTURE IN OBESE PATIENTS UNDERGOING TOTAL HIP REPLACEMENT.

Objective: The aim: To compare the efficiency of analgetic action of Ultrasound-guided FICB and prolonged EA as the components of perioperative multimodal analgesia in ERAS-structure in obese patients undergoing THR.

Patients And Methods: Materials and methods: The retrospective study included 80 patients with obesity, who underwent elective anterolateral THR under conditions of low-flow inhalation anesthesia with sevoflurane in combination with PEA (n1=38) or with FICB (n2=42). Primary endpoints: VAS pain level during the first postoperative day.
