Efficacy Of Scalp Block And Ultrasound Guided TAP Block With Clonidine As Adjuvant To Ropivacaine Versus Intravenous Fentanyl On Intraoperative Hemodynamics And Perioperative Analgesia In Abdominal Bone Flap Cranioplasties
Efficacy Of Scalp Block And Ultrasound Guided TAP Block With Clonidine As Adjuvant To Ropivacaine Versus Intravenous Fentanyl On Intraoperative Hemodynamics And Perioperative Analgesia In Abdominal Bone Flap Cranioplasties: A Prospective, Randomised, Double Blind Study

상세 설명
Scalp blocks with local anaesthetic agents along with general anaesthesia provides intraoperative and postoperative analgesia by blunting the hemodynamic responses to noxious stimuli. The transversus abdominis plane "TAP" block, a regional anaesthesia technique that provides analgesia following abdominal surgery. It involves a single large bolus injection of local anaesthetic into an anatomical space between the internal oblique and transversus abdominis muscles.
Ropivacaine is less cardio toxic, less arrhythmogenic, less toxic to central nervous system (CNS) than bupivacaine, and it also has intrinsic vasoconstrictor property. Clonidine is an alpha-2 receptor agonist, which has a known property of reducing requirement of analgesics in the perioperative period.
This study aimed to assess the efficacy of scalp block and TAP block with 1µg/kg clonidine as adjuvant to 0.2% ropivacaine versus intravenous fentanyl (0.1µg/kg/hr) on intraoperative hemodynamics and perioperative analgesia in abdominal bone flap cranioplasties.

실험적: Scalp & TAP Block (Group T)
Group T received 0.2% Ropivacaine + clonidine 1µg/kg mixture, for ipsilateral scalp block (10ml),TAP block under USG guidance (20ml) and intravenous saline 0.1ml/kg/hr (sham infusion) for continuous infusion.
|
Scalp block is provided by injecting local anaesthetic in the scalp at specific areas to block 6 nerves which are responsible for sensory innervation of the scalp - Supraorbital and supratrochlear nerves, Zygomaticotemporal nerve, Auriculotemporal nerve, Greater and lesser occipital nerves.
The transverse abdominis plane (TAP) block is a peripheral nerve block designed to anesthetize the nerves supplying the anterior abdominal wall (T6 to L1).
It is usually accomplished by a single bolus injection into the transversus abdominis plane through the lumbar triangle of Petit and can be accomplished either by blind landmark based technique or alternatively under ultrasound guidance (as in this study).

활성 비교기: Intravenous Fentanyl (Group C)
Group C received saline, for ipsilateral scalp block (10ml) and TAP block under USG guidance (20ml) and I.V fentanyl 1 µg/kg/hr as analgesic.
|
Fentanyl is a commonly used opioid drug administered for analgesia in the perioperative period.
It may be used as either intermittent bolus administration or continuous infusion or a combination of the two.
Usual infusion doses range from 1-2 microgram/kg/hr, which may be titrated based on intraoperative haemodynamics or postoperative patient reported pain scores.

Difference in Postoperative Rescue Analgesia requirement between groups
기간: Measured at 1, 6 and 24 hours postoperatively.
|
Postoperative rescue analgesia (Inj. paracetamol 1gm I.V) if patient reported pain measured by visual analogue score was ≥ 4. Visual analogue scale (VAS) is a self reported score for estimation of pain which ranges between 1 (no pain) to 10 (worst possible pain). VAS score interpretation: No pain - 1, Mild pain <4, Moderate pain 4-7, Severe pain >7, Worst possible pain =10. |
Measured at 1, 6 and 24 hours postoperatively.
