Dexmedetomidine for Bilateral Superficial Cervical Plexus Block for Reconstructive Tracheal Surgery

The aim of this study is to evaluate the intra- and postoperative efficacy of levobupivacaine versus levobupivacaine - dexmedetomidine for superficial cervical plexus block for upper tracheal resection and reconstruction surgery.

Levobupivacaine Versus Levobupivacaine - Dexmedetomidine for Ultrasound Guided Bilateral Superficial Cervical Plexus Block for Upper Tracheal Resection and Reconstruction Surgery Under General Anesthesia

Tracheal resection and reconstruction (TRR) is the treatment of choice for most patients with tracheal stenosis or tracheal tumors .The post intubation tracheal stenosis is the common indication for (TRR).The immediate postoperative period can be anxiety provoking for some reasons such as requirement to maintain a flexed neck, oxygen mask, and surgical pain which inadequately treated. Bilateral superficial cervical plexus block (BSCPB) is a popular regional anesthesia technique for its feasibility and efficacy. The use of regional anesthesia in combination with general anesthesia may lighten the level of general anesthesia required , provide prolonged postoperative analgesia and reduce the requirements for opioid analgesics Dexmedetomidine is a highly selective ?2 agonist with high affinity for ?2 adrenergic receptors and less ?1 effects, which is responsible for the hypnotic and analgesic effects. Previous trials demonstrated that perineural dexmedetomidine in combination with bupivacaine enhanced sensory and motor block ,without neurotoxicity ,in both experimental and clinical studies. Levobupivacaine, is "S"-enantiomer of bupivacaine, has strongly emerged as a safer alternative for regional anesthesia than bupivacaine . Levobupivacaine has been found to be equally efficacious as bupivacaine, but with a superior pharmacokinetic profile. Clinically, levobupivacaine has been observed to be well tolerated in regional anesthesia techniques both after bolus administration and continuous post-operative infusion.
