Pain Control With Ultrasound-guided Ilioinguinal Iliohypogastric Nerve Block Compared With Local Anesthesia Infiltration in Patients Undergoing Transfemoral Transcatheter Aortic Valve Implantation (TF-TAVI): a Prospective, Randomized Trial
Pain Control With Ultrasound-guided Ilioinguinal Iliohypogastric Nerve Block Compared With Local Anesthesia Infiltration in Patients Undergoing Transfemoral Transcatheter Aortic Valve Implantation (TF-TAVI): a Prospective, Randomized Trial
Ilioinguinal and iliohypogastric (ILIH) nerve blocks are frequently performed for analgesia in inguinal surgery.
The investigators hypothesized that preoperative ultrasound-guided ilioinguinal and iliohypogastric (ILIH) nerve blocks will produce better intraoperative analgesia and less analgesic requirement postoperatively in comparison to commonly used preoperative local infiltration anaesthesia for patients undergoing transfemoral transcatheter aortic valve implantation (TF-TAVI).
It is a prospective, randomized trial.
The patients will be randomized to one of the 2 groups:
Group 1 - NERVE BLOCK. Ultrasound-guided ILIH nerve block will be performed by attending anaesthesiologist.
Group 2 - LOCAL INFILTRATION. Local anaesthetic infiltration of the operative area will be performed by operator.
During surgery patients will receive low-dose propofol infusion in order to achieve conscious sedation level, when indicated.
An extra dose of local anaesthetic drug for infiltration of the surgical field or intravenous fentanyl or/and intravenous paracetamol will be given as rescue analgesics in patients reporting pain sensation.
The patients will be observed for 24 hours. The pain at rest will be assessed using numeric rating scale (NRS 0 -10; 0 = no pain: 10 = max pain imaginable).
On the first postoperative day intravenous analgesics will be given on demand (paracetamol 1 g iv (if NRS <5) and oxycodone 2,5 mg iv (if NRS > or = 5)).
