Suprazygomatic Nerve Block in Tonsillectomy Patients
Sponsor: Assiut University
Summary
The use of suprazygomatic maxillary nerve block to reduce postoperative pain and hospital stay is greater than the use of NSAID and opioids.
Official title: Comparative Study Between Dexmedetomidine Plus Bupivacaine Versus Bupivacaine in Suprazygomatic Maxillary Nerve Block for Management of Postoperative Pain in Tonsillectomy Patients.

Suprazygomatic maxillary nerve block using dexmedetomidne and Bupivacaine
After induction of general anaesthesia blockade of the contents of the pterygopalatine fossa is performed bilaterally before starting surgery as follows: After complete aseptic skin preparation and under ultrasound guidance images are obtained with a high-frequency linear array probe. The ultrasound transducer is placed in the infrazygomatic area, over the maxilla, angled \[45 \]degree cephalad. This probe position allows visualization of the pterygopalatine fossa,The needle is advanced using an out-of-plane approach, and the needle tip can usually be identified during movements. the injectate consisted of \[4\]mL of \[0.5% \]Bupivacaine combined with \[1\]mL of\[ 5\]µg dexmedetomidine. The injectate is delivered over \[15-20 \] seconds, while observing the spread of the local anesthetic under ultrasoundThe same procedure is then repeated on the contralateral side.
